[0035] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] As described in the background section, existing connectors have complex structures and cumbersome assembly processes.

[0037] Therefore, this utility model provides a connector. For example... Figures 1 to 5 As shown, the connector provided by this utility model includes a housing 1, a first terminal block 2, a second terminal block 3, a first conductive wire harness 4, and a second conductive wire harness 5, wherein:

[0038] The first conductive wire harness 4 is crimped to the tail of the first terminal 2, and the first terminal 2 is inserted into the housing 1;

[0039] The second conductive wire harness 5 is crimped to the tail of the second terminal 3, and the second terminal 3 is inserted into the housing 1.

[0040] The assembly process of the connector of this utility model is as follows:

[0041] First, insert the first conductive wire bundle 4 and the second conductive wire bundle 5 into the tail of the first terminal 2 and the second terminal 3, respectively.

[0042] Next, the tail ends of the first terminal 2 and the second terminal 3 are flattened by a press, so that the first conductive wire harness 4 and the second conductive wire harness 5 are respectively crimped onto the first terminal 2 and the second terminal 3.

[0043] Then, insert the first terminal 2 and the second terminal 3 into the housing.

[0044] As can be seen, the connector provided by this utility model uses an integrated first terminal 2 and second terminal 3 as the connecting components between the conductive wire harness and the housing. Through the first terminal 2 and second terminal 3, the first conductive wire harness 4 and the second conductive wire harness 5 can be directly installed onto the housing 1, thereby eliminating the screwing step between the terminal and the wire harness, simplifying the connector structure, and improving assembly efficiency.

[0045] Optionally, the tail of the first terminal 2 is provided with a first crimping sleeve 21, and the first conductive wire harness 4 is inserted into the first crimping sleeve 21 and then crimped and fixed by a press.

[0046] Similarly, the tail of the second terminal 3 is provided with a second crimping sleeve 31, and the second conductive wire harness 5 is inserted into the second crimping sleeve 31 and then crimped and fixed by a press.

[0047] By setting a first crimping sleeve 21 and a second crimping sleeve 31 at the tail of the first terminal 2 and the tail of the second terminal 3 respectively, the first conductive wire harness 4 and the second conductive wire harness 5 are fully inserted into the tail of the first terminal 2 and the tail of the second terminal 3 before being crimped and fixed, thereby ensuring the crimping strength between the first conductive wire harness 4 and the second conductive wire harness 5 and the first terminal 2 and the second terminal 3, and preventing them from falling off.

[0048] Optionally, both the first terminal 2 and the second terminal 3 are formed by stamping metal sheets, such as copper or aluminum stampings. The sidewall thickness of the first crimp sleeve 21 and the second crimp sleeve 31 is 0.5 to 1 mm.

[0049] This configuration ensures that after the first crimp sleeve 21 and the second crimp sleeve 31 are flattened by the press, the crimping strength of the first conductive wire harness 4 and the second conductive wire harness 5 can be guaranteed.

[0050] Optionally, the surfaces of the first terminal 2 and the second terminal 3 are further coated with an anti-oxidation coating. This anti-oxidation coating protects the first terminal 2 and the second terminal 3 from oxidation and corrosion in humid environments, thereby extending the service life of the connector. The anti-oxidation coating can be, for example, a tin layer or a silver layer.

[0051] like Figures 2 to 3 As shown, optionally, both the first terminal 2 and the second terminal 3 include a thinner first insertion section 22 and a thicker second insertion section 23 arranged axially, wherein: the first insertion section 22 is provided with at least one locking ring 24 protruding from the first insertion section 22. The second insertion section 23 is provided with an anti-rotation notch 25.

[0052] After the first terminal 2 and the second terminal 3 are inserted into the housing 1 and fully engaged, the locking ring 24 on the first insertion section 22 locks into the groove inside the housing 1, thereby preventing the first terminal 2 and the second terminal 3 from retracting or loosening. The second insertion section 23 is interference-fitted into the housing 1, and its anti-rotation notch 25 prevents the first terminal 2 and the second terminal 3 from rotating, thereby further improving the stability of the connection between the first terminal 2, the second terminal 3 and the housing 1.

[0053] Optionally, the housing 1 is also provided with a first insertion hole 11 and a second insertion hole 12, wherein the first terminal 2 is inserted into the first insertion hole 11 and the second terminal 3 is inserted into the second insertion hole 12.

[0054] By providing a first insertion hole 11 and a second insertion hole 12 on the housing 1, the first terminal 2 and the second terminal 3 are connected and fixed to the housing 1.

[0055] like Figure 1 , Figures 4 to 5 As shown, optionally, the housing 1 includes a connecting portion 13 and a waterproof portion 14, and the connecting portion 13 is provided with a connecting screw hole 15. By configuring the housing 1 in this way, the connector of this utility model can be screwed and fixed to the target device, and the waterproof performance of the connector is improved.

[0056] Optionally, both the first conductive wire harness 4 and the second conductive wire harness 5 are multi-strand twisted copper wires, and their ends are stripped and crimped to the first terminal 2 and the second terminal 3, respectively. By configuring the first conductive wire harness 4 and the second conductive wire harness 5 in this way, it can be ensured that the first conductive wire harness 4 and the second conductive wire harness 5 form stable conductive contacts with the first terminal 2 and the second terminal 3, respectively.

[0057] The present invention has been described in sufficient detail above, and is therefore quite specific. Those skilled in the art should understand that the descriptions in the embodiments are merely exemplary, and all changes made without departing from the true spirit and scope of the present invention should fall within the protection scope of the present invention.
