Abstract: An electric connector housing that is, even though small in size, capable of fixing a connection terminal with large engagement force. An upper cover (22) is placed on a holder (21) where a connection terminal (11) is fixed, and the holder (21) and the upper cover (22) are connected by a locking mechanism. In this state, the holder (21) and the upper cover (22) firmly prevent the connection terminal (11) from moving in a front-rear direction and a top-bottom direction. The connector housing cooperates with a mating connector to cause connector terminals to be fitted together, and functions as a connector.

Abstract: A connecting terminal has a rectangular tube-like connecting portion including a bottom plate, and a first side plate. A movable contact strip is secured to the bottom plate at a base portion. The movable contact strip is bent into a shape of a mountain. An apex of the mountain constitutes a contact portion. Prior to the formation of the connecting portion, the movable contact strip is folded over the bottom plate. An elongated strip portion of the bottom plate is cut and bent inwardly to form a reinforcing strip. A rear end of the movable contact strip is connected to the bottom plate. A free front end of the reinforcing strip is urged against a lower surface of the contact portion. At a front end of the connecting portion, a guide strip is formed by folding back a front end portion of the bottom plate.

Abstract: A connecting terminal 11 has a rectangular tube-like connecting portion 12 formed at a front side for receiving a cooperating tang-like connecting terminal and a U-shaped core conductor clamping portion 13a and a U-shaped sheath clamping portion 13b at a rear side. In front of the core conductor clamping portion 13a near the connecting portion 12 there are formed plate-like locking strips 14 to extend in a longitudinal direction in an upright fashion. A top portion 13a? of the core conductor clamping portion 13a is coupled substantially linearly with top portions 14? of the locking strips 14 by means of coupling portions 15 to reinforce a root portion of the core conductor clamping portion 13a.

Abstract: In an electrical connector assembly, housings are locked with each other by locking a rear holder provided in a first connector with a cooperating second connector. In a rear holder main body 52 of a rear holder 51 there are formed a plurality of resilient clamping lances 53 which clamp connection terminals 67 inserted into respective terminal receiving holes 62 formed in a housing main body 61. At a middle upper portion of the rear holder 51 there is provided a resilient locking arm 54, and a locking claw 55 is formed on the locking arm. When the housing main body 61 is inserted into a housing main body 71 of a cooperating connector, connection terminals 67 and 72 are coupled with each other. The locking claw 55 provided on the locking arm 54 of the rear holder 51 is engaged with a locking portion 73 of the housing main body 71 of the cooperating second connector.

Abstract: Upon releasing a locking arm from a connecting terminal by inserting a jig through a front holder, the jig could not be erroneously inserted into a terminal inserting hole. Connecting terminals are inserted into a housing, and the connecting terminals are prevented from being pulled out of the housing backwardly by means of locking arms arranged above the respective connecting terminals. The front holder is engaged with the housing by a clamping mechanism in an axial direction and is movable laterally in a direction perpendicular to the axial direction. A pair of terminal inserting holes and an arm operating hole 18 provided for respective connecting terminals are shifted laterally. In a first position of the front holder, the terminal inserting hole is aligned with an axial line of a female-type connecting terminal, but the arm operating hole is shifted laterally from the locking arm.

Abstract: Even in the case of a bar-like small terminal connection, its strength is retained. In (a), a strip (21) made, for example, of a thin metal sheet having a thickness of 0.2 mm and a predetermined width is collapsed by rolling to a thickness of 0.16 mm as in (b). Subsequently, as in (c), the longitudinal opposite sides (22, 23) of the strip (21) are erected with respect to the base plate (24), then inwardly bent, as in (d), and folded onto the base (24), as in (e). Further, the folded opposite sides (22, 23) are erected together with the base plate (24) into a closely contacted state, whereupon as in (f), the folded body is mechanically compressed from all sides into a form having a 0.64-mm square cross section.

Abstract: In a connector terminal into which a cooperating male contact terminal can be smoothly inserted and a movable contact strip can be prevented from being buckled while a desired contact pressure can be attained, a connecting portion 11 is formed into a substantially box shape by folding a bottom plate 13, side plates 14, 15 (14 is not shown) continuously extending from respective sides of the bottom plate and a top plate 16 continuously extending from one of the side plates. A movable contact strip 17 is formed by folding back the top plate 16 around a gently curved portion 17a into a resilient spring having an inverted triangular shape including a contact portion 17b near an inwardly bent middle portion of the movable contact strip 17. A hole 17c is formed at an end portion of the movable contact strip 17 into which an engagement tip 16b formed by folding a part of the top plate 16 inwardly is inserted.

Abstract: A rear holder 4 is inserted into a housing 3 from a rear end surface 24 at a provisional locking position in which the rear holder 4 is inserted into the housing 3 halfway and an insertion of connecting terminals is allowed, as well as at a sufficiently inserted complete locking position at which the inserted connecting terminals are locked. Within the housing 3, there are formed two rows of terminal accommodating holes 28 each accommodating respective connecting terminals. The rear holder 4 is formed in a substantially plate-like shape and includes a main body 41 which is inserted into slits 29 of the housing 3 and locking arms 45 which are inserted into respective terminal accommodating holes 28. A width of a locking arm 45 is slightly smaller than that of a terminal accommodating hole 28. Windows 37 are formed in the outer wall 21 of the housing 3 such that the terminal accommodating holes 28 are communicated with external through the windows 37.

Abstract: A joint connector easy to construct and involving less fabricating cost. The joint connector comprises a housing 3 for accommodating a plurality of connecting terminals 2 in a rear-side portion thereof, a bus bar 6 formed out of an electrically conductive metal plate and accommodated in the housing 3 for jointing any individual ones of the connecting terminals 2, a bus bar holder 7 for holding the bus bar 6, and a front cover 9 mounted to the housing 3 in such a way as to cover the bus bar holder 7. The bus bar holder 7 has a plurality of holes to be used for cutting the bus bar 6 to form an arbitrary circuit. The bus bar holder 7 and the bus bar 6 is mounted in the housing 3 so as to be movable in relation to the housing 3 in a direction orthogonal to the direction of the connecting terminals 2 being housed. When the front cover 9 is set in the housing 3, it causes the bus bar holder 7 to be moved and the bus bar 6 to be jointed with connecting terminals 2.

Abstract: A connector including a reception housing which has four sector-shaped compartments defined by four radial partitions, and four sector-shaped end terminals are inserted into the four sector-shaped compartments from mutually orthogonal directions which are perpendicular to a direction in which an insertion housing is inserted into the reception housing. A number of male terminals are provided on each of the four sector-shaped end terminals, and a number of conductors of a plurality of flat cables are connected to the male terminals. On the insertion housing, a number of female terminals are provided each being connected to respective one of a number of electric wires. The male and female terminals are simultaneously coupled with each other by inserting the insertion housing into the reception housing.
