[0038] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0039] See Figures 1-8 As shown, a multi-interface control connector for an automotive body includes an insulating base 2 and terminals 3 mounted in the insulating base 2.

[0040] The insulating base 2 is integrally injection molded from plastic. The front end of the insulating base 2 is provided with an interface 20, and the insulating base 2 has multiple through interfaces 20 along its rear end for assembling terminal holes 201 of the terminal 3. The inner wall of the terminal hole 201 is recessed with a limiting groove 202, and a step 203 is provided in the limiting groove 202. Both sides of the terminal 3 are provided with spurs 31, and the terminal 3 has outwardly protruding cards 32 stamped along its surface. During assembly, the front end of the terminal 3 passes through the terminal hole 201 and is exposed in the interface 20. The spurs 31 on both sides of the terminal 3 are engaged and positioned with the inner wall of the terminal hole 201, forming a primary positioning. At the same time, the end of the card 32 is pressed into the limiting groove 202 and abuts against the step 203 to prevent the terminal 3 from retracting, forming a secondary positioning. This ensures that the terminal 3 is stably assembled in the insulating base 2. Furthermore, the abutment between the end of the card 32 and the step 203 effectively prevents the terminal from being pushed back after the plug is inserted into the interface 20, thus solving the pin retraction problem and effectively meeting the product holding force requirements.

[0041] In this embodiment, there are multiple spiking spikes 31 on both sides of the terminal 3, which are distributed in a stepped manner.

[0042] In the embodiment, the front end face of the step 203 is a vertical face which abuts against the end of the card 32, and the rear side of the step 203 is provided with an inclined guide face 205 which can play a good guiding role, that is, in the process of assembling the terminal 3 into the terminal hole 201, the card 32 of the terminal 3 first contacts the inclined guide face 205 of the step 203, and then the card 32 of the terminal 3 is gradually compressed with the continuous insertion of the terminal 3, and after the card 32 of the terminal 3 passes the step 203, the card 32 is reset under the elastic force of itself, so that the end of the card 32 is pressed into the limiting groove 202 and abuts against the front end face of the step 203, thereby completing the assembly of the terminal 3 and the insulating seat 2.

[0043] In addition, in order to prevent the terminal 3 from being excessively inserted into the terminal hole 201, the following design is made: the terminal 3 is further provided with outward protruding blocking parts 34 on both sides, and when the terminal 3 is inserted into position, the blocking parts 34 abut against the outside of the rear end opening of the terminal hole 201, at this time, the card 32 of the terminal 3 just passes the step 203, and the end of the card 32 is pressed into the limiting groove 202 and abuts against the front end face of the step 203, thereby completing the assembly of the terminal 3 and the insulating seat 2.

[0044] The design of the card 32 at least includes the following three modes:

[0045] The first mode: the front end of the card 32 is integrally connected with the terminal 3, and the end of the card 32 is inclined and protrudes from top to bottom; and correspondingly, the lower inner wall of the terminal hole 201 is provided with the limiting groove 202 and the step 203.

[0046] The second mode: the front end of the card 32 is integrally connected with the terminal 3, and the end of the card 32 is inclined and protrudes from bottom to top; and correspondingly, the upper inner wall of the terminal hole 201 is provided with the limiting groove 202 and the step 203.
