[0030] like Figures 1 to 4 As shown, this utility model provides a connector. The connector includes a body 1 and a plurality of metal terminals 2. Specifically, the plurality of metal terminals 2 are spaced apart circumferentially through the body 1, and one end of each metal terminal 2 is exposed outside the body 1. The outer wall of each metal terminal 2 has a plurality of protrusions 22 circumferentially protruding to form a knitted structure, which engages with the body 1. Compared to the prior art, the knitted structure on the outer wall of the metal terminals 2 of this connector, when inserted into and engaged with the body 1, prevents the metal terminals 2 from rotating during welding, fixing the direction of the welding cup 21 opening, preventing deviation of the welding cup 21 opening direction, ensuring welding effect, and improving the stability of the connector.

[0031] Furthermore, in this embodiment, the cross-sectional shape of the protrusion 22 is trapezoidal. Of course, in some other embodiments, the cross-sectional shape of the protrusion 22 can be other shapes such as triangles or rectangles.

[0032] Optionally, the main body 1 is provided with a plurality of mounting holes 11, and the plurality of mounting holes 11 are provided one-to-one with a plurality of metal terminals 2, and the metal terminals 2 are engaged with the wall of the mounting holes 11. Specifically, the wall of the mounting holes 11 is provided with a plurality of grooves, and the plurality of grooves are provided one-to-one with a plurality of protrusions 22, and the protrusions 22 can be inserted into the grooves to improve the engagement effect and prevent the metal terminals 2 from loosening and rotating.

[0033] Furthermore, the shape of the groove is the same as that of the protrusion 22, and the outer surface of the protrusion 22 fits into the inner surface of the groove, which can improve the interlocking effect and prevent the metal terminal 2 from loosening and rotating.

[0034] Optionally, the connector also includes a mounting component 3. One end of the main body 1 is provided with a first connecting portion 12. The mounting component 3 is threadedly connected to the first connecting portion 12, and the mounting component 3 is used to connect to an external mechanism. Specifically, the first connecting portion 12 is provided with an external thread, and the mounting component 3 can be threadedly connected to the first connecting portion 12 to lock the structure of the product main body 1 onto the customer's housing or mechanism. Further, the mounting component 3 is a nut. The nut can make the structure of the product main body 1 fit more tightly and stably with the customer's housing or mechanism structure, which can offset the influence of external forces such as vibration, tension, and pressure during operation, prevent the structure from loosening due to force, and maintain the stability and vibration resistance of the main body 1 structure.

[0035] Optionally, the other end of the main body 1 is provided with a second connecting part 13, which can be threadedly connected to an external device. Specifically, the second connecting part 13 is provided with an external thread for connecting to an external device, thereby improving the stability of the connection.

[0036] Optionally, the connector also includes a seal 4, which is disposed between the first connecting portion 12 and the second connecting portion 13. Specifically, when the connector is in operation, the seal 4 is located between the two mating devices, serving to prevent water and dust, isolate external objects, and protect the connector body 1 structure from corrosion and contamination caused by external factors. It also acts as a buffer, damping, and reducing wear on the body 1 structure. Further, the seal 4 is a sealing ring, and the body 1 passes through the seal 4. Even further, the seal 4 is made of rubber, and its deformation under compression improves the sealing effect.

[0037] Optionally, the outer wall of the main body 1 is provided with a boss 14, which is located between the first connecting part 12 and the second connecting part 13. The sealing member 4 is disposed on the boss 14, which can improve the stability of the sealing member 4.

[0038] Furthermore, the boss 14, the first connecting part 12, and the second connecting part 13 are integrally formed, which can improve the stability of the main body 1.

[0039] Optionally, the connector also includes several partitions 5, with a partition 5 provided between two adjacent metal terminals 2, which can prevent interference between different metal terminals 2 and facilitate the welding work.

[0040] Furthermore, several partitions 5 are integrally formed with the main body 1 to improve the stability of the connector.

[0041] Furthermore, in this embodiment, the connector is provided with three metal terminals 2, which are evenly spaced and inserted into the body 1 around the center of the body 1, with a partition 5 provided between every two metal terminals 2. Of course, in some other embodiments, the number of metal terminals 2 is determined according to the actual situation, which will not be elaborated here.

[0042] Furthermore, the three partitions 5 are integrally formed, with their sides connected to each other and the connection point coinciding with the center of the main body 1, so that the included angle between two adjacent partitions 5 is 120°.

[0043] Optionally, in this embodiment, the metal terminal 2 is made of copper, which can effectively conduct current. Of course, in other embodiments, the metal terminal 2 may also use other guiding materials, which will not be elaborated here.

[0044] Furthermore, the main body 1 is made of plastic, which serves as insulation and can prevent electric shock; at the same time, the interlocking structure of the metal terminal 2 and the plastic main body 1 can effectively prevent the metal terminal 2 from loosening and rotating inside the plastic main body 1 after assembly, which would cause the welding cup 21 of the metal terminal 2 to misalign.

[0045] Furthermore, the above description is merely a preferred embodiment of the present invention and the technical principles employed. Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the protection scope of the present invention. Therefore, although the present invention has been described in detail through the above embodiments, the present invention is not limited to the above embodiments, and may include many other equivalent embodiments without departing from the concept of the present invention, the scope of which is determined by the scope of the appended claims.
