[0034] The following will further describe in detail the specific implementation manners of the present utility model in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0035] Refer to Figures 1 to 9 As Figures 1 to 9A detachable wire harness connector as shown, including a connector body 10. A male socket 11 is provided at the front end of the connector body 10. A pin socket 12 for installing pins (not shown in the figure) is provided at the rear end of the connector body 10. A dovetail groove / T-slot 13 is provided on the upper surface of the connector body 10 and runs in the front-rear direction of the connector body 10. It further includes a fixing base 20.

Elastic arms 23 that extend obliquely towards the fixing base 20 are provided on both sides of the extending end of the connecting column 22 in the front and rear directions of the connector body 10. The distance between the extending ends of the two elastic arms 23 gradually increases in the extending direction. The extending ends of the elastic arms 23 approach each other by using their own elasticity when subjected to a squeezing force (so as to enter the fixing holes of the car door panel or the body frame). An anti-disengagement surface 231 is provided on the side of the extending end of the elastic arm 23 away from the other elastic arm 23. Anti-disengagement teeth 232 are provided on the anti-disengagement surface 231. A support bowl 24 is provided at the connection between the fixing base 20 and the connecting column 22, and the mouth of the support bowl 24 faces the extending end of the connecting column 22.

[0036] In the above structure, the fixing base 20 is separately connected to the fixing holes of the car door panel or the body frame, so that it can be first fixed to the car door panel or the body frame, and then the connector body 10 realizes detachable docking through the cooperation of the dovetail groove / T-slot 13 and the dovetail block / T-block 21 of the fixing base 20, providing stable and reliable fixation for the connector body 10. Affected by the wire harness in the front-rear direction, the connector body 10 is prone to pitching and swinging (refer to Figure 3 as shown). Therefore, the elastic arms 23 are arranged on both sides of the connecting column 22 in the front and rear directions of the connector body 10, and the distance between the anti-disengagement teeth 232 and the connecting column 22 is increased as much as possible. In this way, the pitching and swinging in the front-rear direction can be effectively restricted in cooperation with the anti-disengagement teeth 232, and the support bowl 24 is used to provide elastic support in the axial direction of the connecting column 22, making the fixation of the connector body 10 more stable.

[0037] In this embodiment, the anti-disengagement surface 231 is inclined, and the distance between the two anti-disengagement surfaces 231 gradually decreases on the side close to the fixing base 20.

[0038] In the above structure, the anti-disengagement surface 231 is adapted to the fixing hole.

On one of the connection blocks 14 at one end of the opening direction of the sliding groove 141, a blocking portion 142 is provided. The two connection blocks 14 and the sliding grooves 141 together form a dovetail groove / T-shaped groove 13.

[0042] In the above structure, it is ensured that the dovetail groove / T-shaped groove 13 and the dovetail block / T-shaped block 21 can be well adapted, and the blocking portion 142 can provide positioning and blocking when the dovetail block / T-shaped block 21 slides into the limit position.

[0043] In this embodiment, a first anti-disengagement block 15 is provided between the two connection blocks 14; on the surface of the dovetail block / T-shaped block 21 facing the connector body 10, a second anti-disengagement block 211 adapted to be engaged with the first anti-disengagement block 15 to achieve anti-disengagement is provided.

[0044] In the above structure, the first anti-disengagement block 15 and the second anti-disengagement block 211 are adapted to prevent the dovetail block / T-shaped block 21 from disengaging in the reverse direction after it slides into the dovetail groove / T-shaped groove 13.

[0045] In this embodiment, on the surface of the dovetail block / T-shaped block 21 facing the connector body 10, an unlocking groove 212 is further provided and opened in the front-back direction of the connector body 10, and the second anti-disengagement block 211 is located on the opening path of the unlocking groove 212.

[0046] In the above structure, when it is necessary to separate the connector body 10 from the fixed seat 20, a crowbar or a flat-blade screwdriver can be inserted into the unlocking groove 212 for support, and through the elastic deformation of the connector body 10 and the fixed seat 20 itself, the first anti-disengagement block 15 and the second anti-disengagement block 211 are separated from each other.

[0047] In this embodiment, the first anti-disengagement block 15 is located on the side of the connection block 14 away from the blocking portion 142. On the side of the first anti-disengagement block 15 away from the blocking portion 142, a first guiding portion 151 is provided; on the side of the second anti-disengagement block 211 facing the blocking portion 142, a second guiding portion 2111 is provided; when the dovetail block / T-shaped block 21 is slidably installed in the dovetail groove / T-shaped groove 13, the first guiding portion 151 and the second guiding portion 2111 guide and yield to each other so that the second anti-disengagement block 211 can cross the first anti-disengagement block 15 to achieve fixed anti-disengagement.

[0048] In this embodiment, the connector body 10 is integrally formed by injection molding; the fixed seat 20, the connecting column 22, the elastic arm 23 and the support bowl 24 are all integrally injection molded.

[0049] In the above structure, it has the advantages of convenient production, high dimensional accuracy and high overall strength.

[0051] In the above structure, the reinforcing rib plate 221 is used to assist in strengthening one side of the connecting column 22 in the width direction, resulting in a reduction in strength on the other side. When it is necessary to remove the fixed seat 20 from the fixing hole, by twisting in the rolling direction (refer to Figure 9 shown), the connecting column 22 can be broken at the weakened part.

[0052] In this embodiment, the connecting column 22 is provided with a material-saving groove 222 on both sides in the width direction of the connector body 10.

[0053] In the above structure, the material-saving groove 222 can save injection molding materials and provide a breaking point for the rolling removal of the fixed seat 20.

Therefore, the elastic arms 23 are arranged on both sides of the connecting column 22 in the front and rear directions of the connector body 10, and the distance between the anti-detachment teeth 232 and the connecting column 22 is increased as much as possible. In this way, the pitching and swinging in the front and rear directions can be effectively restricted in cooperation with the anti-detachment teeth 232, and the support bowl 24 is used to provide elastic support in the axial direction of the connecting column 22, making the fixation of the connector body 10 more stable.
