[0034] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0035] This embodiment provides a connector with an anti-mislocking function. Figures 1 to 6As shown, the connector with anti-mistake locking function of this embodiment includes a first housing component 1 and a second housing component 2. The first housing component 1 has a first housing 11. The first end 11a of the first housing 11 is provided with an electrical connector 12 and a wire clamping component for clamping the electrical connector 12. The first housing 11 has a chamber inside, and the wire clamping component is detachably provided on the first housing 11. The second housing component 2 has a second housing 21, and the second housing 21 is assembled and matched with the second end 11b of the first housing 11. In addition, the first housing component 1 also has a pull button 3, a tightening member 4 and an anti-mistake disassembly component 5. Among them:

[0036] The pull-fastener 3 is disposed on the first housing 11 by pivoting, and the pull-fastener 3 is configured to be fastened to or not with the second housing 21 by rotating back and forth relative to the first housing 11;

[0037] The tightening member 4 is detachably tightened on the first end 11a of the first housing 11 to fix the wire clamping assembly;

[0038] The anti-mistaken disassembly component 5 is detachably arranged on the first shell 11, and has a restricted structure that is restricted and fixed between the tightening member 4 and the second end 11b of the first shell 11, and the anti-mistaken disassembly component 5 also has a restricting structure that limits the rotational stroke of the pull button 3 to avoid the pull button 3 from releasing the fastening relationship with the second shell 21.

[0039] In the connector with anti-mistaken locking function of this embodiment, a plate fastener capable of pivoting relative to the first shell is arranged on the first shell, and the fastening to the second shell is completed by the back-and-forth rotation of the pull fastener, and a screwing member for fixing the wire clamping assembly and an anti-mistaken disassembly component for limiting the fixing of the screwing member to the first shell are also provided. The limiting structure of the anti-mistaken disassembly component limits the rotation stroke of the pull fastener to avoid the release of the fastening relationship between the pull fastener and the second shell, and the anti-mistaken disassembly component and the screwing member can be detachably arranged on the first shell. In this way, when it is necessary to release the assembly relationship between the first shell assembly and the second shell assembly, the screwing member can only be removed from the first shell in strict accordance with the first step, and then the anti-mistaken disassembly component can be removed, and then the pull fastener can be applied with a pulling force to release the fastening relationship between the pull fastener and the second shell, thereby realizing the release of the assembly relationship between the first shell assembly and the second shell assembly. Once the tightening member and the anti-mistaken disassembly component are operated in the wrong order, the anti-mistaken disassembly component cannot be removed, and the restriction on the rotational travel of the latch member by the anti-mistaken disassembly component cannot be released, thereby avoiding the incorrect unlocking of the assembly relationship between the first shell component and the second shell component.

[0041] In order to enhance the fastening relationship between the pull-pull member and the second shell, and to ensure the stability of the assembly relationship between the first shell assembly and the second shell assembly, the connector with anti-misinterpretation locking function of this embodiment also includes a fixing member 6 configured to fix the pull-pull member 3 to the first shell 11, and the fixing member 6 is detachably fastened to the first shell 11. For example, in this embodiment, the fixing member 6 here is a screw, and a screw hole 330 is formed on the pull-pull member 3. The screw is fastened to the first shell after passing through the screw hole, thereby firmly fixing the pull-pull member. Of course, an elastic member 7 can be sleeved on the outside of the screw as needed, so that the elastic member is compressed in the screw hole of the pull-pull member.

[0042] Specifically in this embodiment, see Figure 5 As shown, the above-mentioned pull buckle member 3 includes a pull buckle body 31, a pivot part 32 and a movable part 33.

As a pivotal rotation mode of the pivot part 32 on the first housing 11, the pivot part 32 here is formed with a pin hole 320, and a pin corresponding to the pin hole 320 is arranged on the first housing 11 to realize the rotation of the pivot part.

[0043] As a structure for fastening the pull member to the second housing, in this embodiment, the pull member 3 has a fastener 34 that cooperates with the second housing 21 to complete the fastening, and the fastener 34 is arranged near the pivot portion 32. The second housing 21 is provided with a snap-fitting portion 211 that snap-fits with the fastener 34.

[0044] Specifically in this embodiment, see Figure 6 As shown, the anti-mistaken disassembly component 5 includes an anti-mistaken disassembly component body 51 and a fixing portion 52 formed on the anti-mistaken disassembly component body 51, and a slot 30 is provided on the buckle component body 31 of the buckle member 3 for the fixing portion 52 of the anti-mistaken disassembly component 5 to be inserted into; wherein the fixing portion 52 has an extension portion 521 which is configured to be located outside the slot 30 after the fixing portion is inserted into the slot 30, and the fixing portion 52 is the limiting structure.

[0045] As a method for arranging the anti-disassembly component on the first end of the first housing, see Figure 6As shown, the anti-disassembly part body 51 of this embodiment is formed with a fixing hole 510 with a crack for fixing the first end 11a of the first shell 11, and the structure located on the anti-disassembly part body 51 and close to the fixing hole 510 is the restricted structure.

[0046] As a method for fixing the wire clamping assembly by means of a mating tightening piece, in the connector of this embodiment, the first end 11a of the first shell 11 is formed with an extension end 111 with an external thread, and the extension end 111 has a cavity (not shown in the figure) connected to the inner chamber of the first shell, and the wire clamping assembly is located in the cavity; wherein the tightening piece 4 is tightened to the extension end 111 of the first shell 11 by mating with the external thread.
