Abstract: A metal plate contact has two slits running from an upper end towards a bottom wall. First and second trench for receiving trunk and branching cables, respectively, and a recess for mounting a contact that crosses these trenches are created in a middle portion in a lateral direction of a housing. Left and right movable ends are connected to the middle portion on the two sides in a longitudinal direction via a connection band. The movable ends can be folded towards the top of the middle portion. First and second upper side trenches for covering the top of the first trench and covering the top of the second trench, respectively, are created in these movable ends. A wire lid for positioning a cable end is formed in one end or in the two ends of the second trench or of the second upper side trench.

Abstract: A wire line connector includes a main contact body is provided with an electrical connection trench into which an insulated wire is compressed at the rear end, a protrusion that engages with a housing and prevents disconnection in the middle portion, and a contact portion at the front end. The portion of the contact portion on the rear end side forms parallel walls and the portion on the front end side forms protruding parallel walls in such a manner that the outer surfaces of the protruding walls and the inner surfaces of the parallel walls make contact with each other when the two connector portions are connected. The housing is provided with a step to be engaged with the protrusion for preventing disconnection of the main contact body, and an engaging hole and an engaging protrusion which prevent disconnection when the housing is connected with another housing.

Abstract: A method for manufacturing an integrally formed insulator assembly, comprises forming a unit segment of a set overall length including a plurality of insulator sleeves of plastic material disposed parallel to each other at proper intervals and belting web portions between the sleeves. The segment is then fed in a sleeve clamper wherein an electrical connector element is inserted in a respective one of the sleeves and proper external force is applied on the sleeve to clamp up the connector element in proper electrical conduction state. Another segment is similarly formed up and is integrally united with the previous segment at the longitudinal end thereof. Any desired length of the integrally united product is obtained by repeating such extension. Firm unification of the segments is assured by providing proper complementary fitting engagement structure in such mutually united portions.

Abstract: A continual crimper for pressing an electric wire to an electric terminal, which is belted intermittently one by one, to make the wire fixed to the terminal respectively. The crimper is so constructed that the intermittently belted terminals may be transferred to its position of the next pressing step at a predetermined distance in relation with the returning action of a movable die which presses the terminal.
