Abstract: When a connector housing 20 and an equipment connector 10 are correctly joined, a regulating groove 24D of a retainer 24 of the housing 20 fits with a rib 16 of the equipment connector 10, thereby allowing the two housings 10 and 20 to be fitted together. The position of groove 24D may be varied to suit different positions of rib 16, thereby permitting a common connector housing to be made suitable for a specific equipment connector having an appropriate rib. The shape of the retainer 24 is simpler than the shape of the housing main body 21. Consequently, the cost of the mould for the retainer 24 is lower.

Abstract: The invention provides a moulded plastic connector in which the mould is not weakened, and in which terminal fittings are not exposed. Portions of a side of a retainer attachment hole 13, which are opposite an insertion hole 14 for a retainer 20, are open to form mould removing holes 15, the remaining portion being covered by a wall 16. This wall 16 reduces the degree to which terminal fittings 19 are exposed from the interior of a housing 10. When a connector C is to be moulded, anterior ends of a first mould 30 (which is removed from the housing 10 via the insertion hole 14) and a second mould 40 (which is removed via the mould removing holes 15) fit together within the retainer attachment hole 13 in a doubled-over manner in a direction which intersects with the direction of mould removal. Consequently, the strength of the moulds 30 and 40 is not decreased.

Abstract: A plurality of electric wires 25 are distributed in an aligned manner on a distribution face 13 of a housing 10, a longitudinal direction of distribution thereof being at approximately right angles to a direction of attachment of insulation displacement terminal fittings 30. A cover 40 is attached from above. Walls 43 are provided on the cover 40 at locations which partition the spaces between distribution paths of the adjacent electric wires 25 and which also pass either side of the terminal fittings 30. The walls 43 permit incorrect attachment to be detected by interference. Front and rear walls 45F,45R are of different height to ensure correct orientation of the cover 40.

Abstract: A terminal fitting (30) is provided for contact with a contact terminal (20) and for inverted insertion into a cavity (11). The terminal (30) has a cover (40) and a terminal main body (31). The cover (40) has a relatively high strength and is integrally secured to the terminal main body (31) in such a manner as to cover substantially entirely a connection portion (32). Cuts are made in opposite side walls of the cover (40) and the cut portions are bent to project outward to form elastically deformable metal locking portions (42). Openings (45) are provided in surfaces of the cover (40) adjacent to the side walls that have the metal locking portions (42). Contact portions (36) are provided on the connection portion (32) inside the cover (40) and can be brought into contact with a shorting terminal (20) that is exposed through the openings (45). The contact portions (36) and the metal locking portions (42) are displaced substantially by 90° from each other.

Abstract: The present invention relates to a connector wherein a retainer slides from a side direction of a connector housing in which it is to be installed. An object of the present invention is to provide a connector capable of preventing a connector connected in a condition in which the retainer is not installed, and transferred to subsequent processes. As a solution, a housing main body is provided with a slider capable of sliding, the slider is hooked in a regulating position in a condition in which the retainer is not installed on the housing main body, and interferes with detection pins provided on a male connector. Therefore the connection of both the connectors becomes impossible. To the contrary, when the retainer is installed on the housing main body, the slider is transferred from a regulating position to a permitting position by the slider contact part provided on the retainer which does not interfere with the detection pins, and the connection of both connectors is permitted.

Abstract: A connector is provided to independently perform connection detection and short releasing functions. The connector includes a connection detecting member 55 and a separate short releasing member 50. A connector is assembled by fitting a female connector housing 21 into a male connector housing 11, mounting the connection detecting member 55 and then mounting the short releasing member 50. The connected state of the connector housings 11, 21 is detected based on whether or not the connection detecting member 55 can be mounted on the female connector housing 21. If the short releasing member 50 is mounted after the two connector housings are properly connected, the shorted state of male tabs 13 is released in the male connector housing. Since the connection detecting member 55 and the short releasing member 50 are such separate members as to be independently mountable and detachable, both the connection detection and the short releasing can properly be performed.

Abstract: A female housing 20 is provided with a terminal accommodating portion 21 for accommodating female terminal fittings 24, a rubber ring 33 to be adhered to the inner circumferential surface of a receptacle of a male housing 10 to be connected with 20 is fitted on the outer circumferential surface of the terminal accommodating portion 21 and a spring holder 50 accommodating coil springs 60 provided with spring pressing members 59 at their front ends is mounted between the terminal accommodating portion 21 and an outer tubular portion 23. The rubber ring 33 is movable from a temporary mount position where a clearance is formed between the inner surface thereof and the outer surface of a locking portion 31 of the retainer 30 to a proper mount position where it is adhered to the terminal accommodating portion 21 over an entire circumference as the housings 10, 20 are connected with each other.

Abstract: A connector is provided to avoid problems in producing and handling a wiring harness when one conductive path which is branched from a main path of the wiring harness and returns thereto again after passing via branch paths is constructed. To achieve this objective, a cutter 25 is provided between two blade-type terminal fittings 20a, 20d of a joint connector 10, and a main wire Waa is connected with the two blade-type terminal fittings and cut therebetween by the cutter 25. By connecting a branching connector 40 with the joint connector 10, branch terminal fittings 41a, 41d are connected with the blade-type terminal fittings 20a, 20d. Since all main wires forming a wiring harness WH are allowed to have the same length and to be bundled together, there is no problem in producing and handling the wiring harness WH.

Abstract: A lever-type electrical connector has connector housings and a lever rotatably mounted on a first connector housing. The lever has a cam track with an entrance end. A cam pin on the second connector housing enters the entrance end of the cam track when the connector housings are brought together with the lever in a waiting position, and by the interaction of the cam pin and the cam track, when thereafter the lever is rotated to a locking position, the connector housings are drawn together into a fully fitted conformation. At least one of the lever and the cam pin has an edge surface inclined with respect to the fitting direction whereby, when the lever is incorrectly located so that the pin is not received in the entrance end of said cam track, the lever and the pin interact at the inclined edge surface to prevent the lever from over-riding the pin.

Abstract: A connector is provided with a retainer which can prevent a retainer insertion hole from being exposed to the outside and which has a strong force for retaining terminal fittings. The retainer includes a pair of insertion portions 41, 42 having different lengths extend in parallel from a base portion 43 of a retainer 40, and tapered surfaces 32, 33 for guiding the respective insertion portions 41, 42 in a direction oblique to the insertion direction of terminal fittings 20 are provided at the back of a pair of insertion holes 30, 31 formed in a housing 10 in conformity with the insertion portions 41, 42. When the retainer 40 is guided in the oblique direction, lock projections 45 provided on the retainer 40 directly lock the terminal fittings 20. Since the terminal fittings 20 are directly locked by the retainer 40 in this connector, they can be retained with a strong force.

When the retainer 40 is guided in the oblique direction, lock projections 45 provided on the retainer 40 directly lock the terminal fittings 20. Since the terminal fittings 20 are directly locked by the retainer 40 in this connector, they can be retained with a strong force.

Abstract: A cramping terminal is provided to have a strong groove portion and an electrical connection with an improved reliability. The cramping terminal 20 has a side cramping blade 29 provided in a groove portion 25. The side cramping blade 29 is formed by bending projections 40 that define the side cramping blade 29 in different directions. Accordingly, holes 42 formed by the projections 40 are left in one side wall 27 more toward one end of the groove portion 25 than the side cramping blade 29 and in the other side wall more toward the other end of the groove portion 25 than the side cramping blade 29. Therefore, the side walls 27 remain opposite to the hole 42, enhancing the strength of the groove portion 25.

Abstract: A connector is provided with a retainer 30 that is rotatable in a housing 10 about an insertion portion 33. When the retainer 30 is rotated to its lock position, lock projections 32 provided on the insertion portion 33 lock the terminal fittings 20. Since the retainer 30 can directly lock the terminal fittings 20 in this connector, the terminal fittings 20 can be retained with a strong force. Further, since a retainer insertion hole 31 is formed in the front surface of the housing 10, it is not exposed to the outside by being covered by a mating connector. In other words, the inventive connector has advantages of both side retainer type and front retainer type connectors of prior art and retains the terminal fittings 20 with a large force while being designed to be watertight.

Abstract: An electrical connector can be fitted with either an electric wire cover (40) or a component installation cover (30), the choice of cover corresponding to the presence or absence of an electrical component (39) in the corresponding connector housing. The electric wire cover (40) or the component installation cover (30) are installed detachably and, as a result, the relatively expensive connector housing (10) is provided with shared components which can be adapted to the intended use.

Abstract: A connector is provided with a retainer in which a retainer insertion hole is covered and terminal fittings are retained with a large force. The connector has an inner housing 12 fittable into an outer housing 11. A retainer insertion hole 23 is so provided as to extend in a direction normal to the extension of cavities 15. A retainer 40 inserted into this insertion 23 faces rear end surfaces 31B of main portions 31 of terminal fittings 30 to prevent the terminal fittings 30 from coming out. According to this embodiment, since the retainer 40 directly prevents the terminal fittings 30 from coming out, the terminal fittings 30 can be retained with a large force. Further, the retainer insertion hole 23 in the inner housing is covered by the outer housing 11 and therefore is not exposed.

Abstract: A male terminal fitting 20 is formed by bending, for example, copper alloy metal plate, and comprises, in a unified manner, a barrel member 30, a contact protrusion 40 for insertion into a female terminal fitting, and a tubular member 50 located between these. The terminal fitting comprises an overlapping plate 53 that overlaps with a roof wall 52 of the tubular member 50, a strengthening plate 54 extending in a unified manner from the anterior end of the overlapping plate 53 entering into the root portion of the contact protrusion 40. As a result, the strength of the contact protrusion 40 is increased and change of shape thereof due to an external force is prevented.

Abstract: A pair of resilient contacts 12 facing each other are made into a C shape. The base end of each contact 12 connects to a tubular member 11. In this manner, the contact 12 has a strengthening wall 13 formed along the direction of bending. Thus when a male terminal fitting C is inserted between the contacts 12, the strengthening walls 13 bend in a direction that is parallel to the wall face and consequently an increased clamping force can be provided notwithstanding that the thickness of the terminal material is not great. Miniaturization of the terminal is facilitated.

Abstract: A cover 11 for an electrical terminal is formed by bending a stainless steel stamping into an angular tubular shape. A right side plate 15 of the cover 11 is formed so as to protrude above a plate face of an upper face plate 12, a lance 20 being formed on this plate face by shearing. This protruding portion serves as a stabilizer 17 which is formed in a stepped shape so as to be retracted inwards with respect to the outer face of the right side plate 15. The anterior and posterior ends of the upper face plate 12 have a pair of inserting members 22 formed thereon. The stabilizer 17 has a pair of fitting grooves 23 formed by cutting away into the protruding portion thereof. When the stamping is bent to the angular tubular shape, the inserting members 22 fit into the corresponding groove 23 to improve the stability of the cover, and without protruding beyond the right side plate 15.
