Detailed Description
A connector comprises a terminal wiring harness 1, a rubber shell 2 and a needle seat 3, wherein the terminal wiring harness 1 and the needle seat 3 are respectively inserted at two ends of the rubber shell 2, a middle needle 4 is inserted into the needle seat 3, the inner end of the middle needle 4 is inserted into a needle jack of a terminal at the inner end of the terminal wiring harness 1, one end of the rubber shell 2 inserted into the terminal wiring harness 1 is connected with a locking strip 5 for fixing the terminal wiring harness 1 in an inserting mode, the locking strip 5 comprises a locking part 5-1 for extruding the terminal of the terminal wiring harness 1 into the rubber shell terminal jack 2-1 of the rubber shell 2, at least two locking strip hooks 2-2 are integrally molded outside the rubber shell 2, and locking strip hanging grooves 5-2 matched with the locking strip hooks 2-2 are integrally molded on the locking strip 5.
The utility model discloses in the assembly, insert terminal pencil 1 in gluing shell terminal jack 2-1 of gluing shell 2 earlier, lock tooth piece 1-1 hook of terminal pencil 1 realizes once locking in 2-7 in gluing the locked groove of shell 2. Then, the locking part 5-1 of the locking strip 5 is inserted into the rubber shell terminal insertion hole 2-1, and the inner end of the locking part 5-1 is pressed against the terminal secondary locking plate 1-2 of the terminal wire harness 1 to realize secondary locking.
The locking part 5-1 fills the gap between the inside of the rubber shell 2 and the terminal wiring harness 1, so that the terminal of the terminal wiring harness 1 has a reduced moving range in the rubber shell 2, and the terminal and the middle needle 4 in the needle seat 3 are more stably conducted.
The utility model discloses a terminal pencil 1 can set up to 4, or 6, or its quantity that needs, like figure 7, the quantity of terminal pencil 1 is 6.
Two locking bar protection walls 2-9 are integrally molded on the upper portion of the rubber casing 2, the two locking bar protection walls 2-9 are arranged in parallel, two locking bar hooks 2-2 are arranged, and the two locking bar hooks 2-2 are arranged on the upper portion of the rubber casing 2 or on two sides of the rubber casing 2 respectively.
