【Detailed ways】

1 to 2, the utility model cable connector 100 is a wire harness connector, which includes an insulating body 1, a number of conductive terminals 2 accommodated in the insulating body 1, and wires electrically connected to the conductive terminals 2. Cable 3.

Please refer to Figures 2 to 4, the insulating body 1 is generally a T-shaped structure, which is integrally formed of insulating materials, and includes a base 11 and a mating connector (not shown) extending forward from the base 11. Docking part 12 for docking.

The docking part 12 is roughly a rectangular plate with a certain thickness, including a top wall 121, a bottom wall 122, a pair of side walls 123, and a number of terminal channels 124 running through the front and back of the insulating body 1 along the docking direction. The terminal channels 124 are arranged in a horizontal direction. One row, the number depends on the needs of use. The top wall 121 only covers the front end of the docking portion 12 , so a section of the terminal channel 124 located at the docking portion 12 is exposed and communicated with the outside. The sidewalls 123 on the left and right sides are respectively provided with a rib 1231 extending along the docking direction for guiding the cable connector 100 to dock with the docking connector.

A plurality of clamping pieces 112 corresponding to the terminal channels 124 are provided on the upper surface of the base 11 , and these clamping pieces 112 respectively extend from the base 11 to the docking portion 12 and correspond to exposed portions of the terminal channels 124 . Each clamping piece 112 does not extend along a straight line, and its end 1120 extends into the interior of the terminal channel 124 and is substantially flush with the outer wall of the docking portion 12 .

The terminal channel 124 is jointly formed by a number of inner walls (not shown), which includes a first opening 1241 facing forward and a second opening 1242 behind the first opening 1241. The second opening 1242 extends backward and connects the docking portion 12 and the base. 11, the first opening 1241 is in the shape of a trumpet with a large front and a small rear.

The terminal channel 124 is provided with a blocking portion 1243 extending in the front-rear direction. The blocking portion 1243 protrudes backward from the inner surface of the front wall 125 of the docking portion 12 , and is located in the second opening 1242 of the terminal channel 124 and is in the shape of a cantilever. .

The conductive terminals 2 are accommodated in the terminal channel 124 of the insulating body 1 in one-to-one correspondence. Each conductive terminal 2 includes a contact end 21 received in the docking portion 12 to connect with a terminal of the mating connector, and is located above the contact end 21 and horizontally. The plate body portion 22 and the clamping portion 23 located at the end are provided, and the clamping portion 23 clamps the cable 3 and is electrically connected thereto. The plate body part 22 is flat, and it is connected with the clamping part 23 in the length direction, and is connected with the contact end 21 in the second half of the plate body part 22 in the vertical direction, and the plate body part 22 and the contact end The upper edges of 21 are spaced apart to form gaps. The upper surface of the board body 22 is turned outward to form a stab 221 extending obliquely upward. When the conductive terminal 2 is assembled into the insulating body 1 (as shown in FIG. 4 ), the stab 221 abuts against the front end of the corresponding holding piece 112 to prevent the conductive terminal 2 from moving in the front-back direction. The front end of the plate body portion 22 is located above the blocking portion 1243, that is, the blocking portion 1243 extends into the space between the contact end 21 and the plate body portion 22. When the conductive terminal 2 has an axial rotation tendency, the plate body portion 22 It can be blocked by the blocking portion 1243 and cannot continue to rotate, so as to limit the rotation of the conductive terminal 2 in the terminal channel 124 .
