[0030] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0031] Please also read Figures 1 to 5 The high-density push-pull self-locking connector with strong anti-interference provided by the embodiment of the present application is now described. The high-density push-pull self-locking connector with strong anti-interference 10 comprises: a first metal shell 11, a first plastic body 12 and a plurality of plug terminals 14.

[0032] The first metal shell 11 has a through hole that passes through its front and rear surfaces. The first plastic body 12 is installed in the through hole and forms a first plug interface 13 for the connector plug to be inserted with the first metal shell 11. A first support plate 121 is embedded in the first plastic body 12. A plurality of plug terminals 14 are embedded in the first plastic body 12, and the first support plate 121 separates two adjacent plug terminals 14. By embedding the first support plate 121 in the first plastic body 12, two adjacent plug terminals 14 are separated by the first support plate 121. On the one hand, the overall strength of the first plastic body 12 can be strengthened by the first support plate 121, and multiple plug terminals 14 can be embedded under the same size, thereby improving the setting density of the plug terminals 14. On the other hand, the first support plate 121 can separate two adjacent plug terminals 14, reduce the problem of signal interference between the plug terminals 14, and improve the overall anti-interference ability of the connector.

[0033] In some embodiments of the present application, the first support plate 121 is arranged in a "cross" shape, the plurality of plug terminals 14 have at least four, the four plug terminals 14 are arranged in a square with four points of spacing, and the first support plate 121 is located between the four plug terminals 14. The first support plate 121 is stamped and formed by a copper plate, an aluminum plate, a nickel plate or a carbon fiber plate, and the outer surface of the first support plate 121 is coated with an anti-interference coating layer 122. Specifically, the surface of the first support plate 121 is provided with grooves arranged at equal intervals, and after the anti-interference coating layer 122 is formed on the surface of the first support plate 121, the anti-interference coating layer 122 can be integrated into the grooves to improve the adhesion ability of the anti-interference coating layer 122.

[0034] Next, a first buckling groove 114 is provided in the through hole of the first metal shell 11, and a first buckling protrusion 123 is provided on the first plastic body 12 for buckling into the first buckling groove 114. During assembly, the first plastic body 12 is inserted into the through hole from the rear side of the first metal shell 11, and then the first plastic body 12 is pushed forward to buckle the first buckling protrusion 123 into the first buckling groove, thereby completing the assembly operation of the first plastic body 12.

[0035] Specifically, the plug-in terminal 14 includes a plug-in portion 141, an inlay portion 142 integrally formed at the end of the plug-in portion 141, and a connection portion 143 integrally formed at the end of the inlay portion 142. The plug-in portion 141 extends forward to the first plug port 13, the inlay portion 142 is embedded in the plastic of the first plastic body 12, and the connection portion 143 extends backward to protrude from the rear side of the first plastic body 12. A first welding notch 144 is provided at the end of the connection portion 143. After the outer sheath of the wire harness is stripped off, the copper wire is inserted into the first welding notch 144 to weld and fix each plug-in terminal 14 together.

[0036] In more detail, a first push-pull shell 15 is movably mounted on the outer side of the first metal shell 11, and a first clamping arm 111 is provided on the peripheral side of the first metal shell 11; when the first push-pull shell 15 moves backward relative to the first metal shell 11, it can push the front end of the first clamping arm 111 to move toward the center direction of the first plug-in port 13.

[0037] When in use, the connector plug is inserted into the first plug interface 13, and then the first push-pull shell 15 is pushed to move backward. During the backward movement of the first push-pull shell 15, the front side of the first notch 151 will abut against the first inclined surface 113. As the first notch 151 moves backward synchronously, the front end of the first clamping arm 111 can be moved toward the center direction of the first plug interface 13, so that the front end of the first clamping arm 111 abuts against the surface of the connector plug to clamp and fix the connector plug; when the connector plug needs to be unplugged, only the first push-pull shell 15 needs to be pulled forward to release the clamping force of the first clamping arm 111 on the connector plug, and the connector plug can be unplugged from the first plug interface 13.

[0038] Preferably, the front end of the outer side surface of the first clamp arm 111 is provided with a first protrusion 112, and the outer side surface of the first protrusion 112 is provided with a first inclined surface 113, and the first inclined surface 113 is arranged to be inclined outward from front to back; the first push-pull shell 15 is provided with a first notch 151, and the first protrusion 112 is located in the first notch 151; when the first push-pull shell 15 moves backward relative to the first metal shell 11, the front side of the first notch 151 can abut against the first inclined surface 113 and act on the front end of the first clamp arm 111 to move toward the center direction of the first plug-in port 13. There are at least three first clamp arms 111, and the three first clamp arms 111 are arranged in a circular shape with equal intervals along the outer side surface of the first metal shell 11. Correspondingly, the number of first notches 151 is equal to the number of first clamp arms 111, and one first notch 151 corresponds to one first protrusion 112 for insertion; when in use, multiple first clamp arms 111 can be pushed simultaneously by one first push-pull shell 15 to clamp the connector plug.

[0039] In other embodiments of the present application, a first support sleeve 16 is further included. The first support sleeve 16 is installed at the rear end of the first metal shell 11. The first support sleeve 16 has a first wire hole 161 that penetrates the front and rear surfaces thereof and is used for inserting the wire harness. When wiring, the wire harness is inserted from the first wire hole 161, and then the wire harness is welded one by one to each plug-in terminal 14, and then the first support sleeve 16 is installed at the rear end of the first metal shell 11. The first support sleeve 16 can support the wire harness to prevent the wire harness from being separated from the plug-in terminal 14, thereby improving the reliability of the connector.

[0040] The above are only preferred embodiments of the present invention, and only specifically describe the technical principles of the present invention. These descriptions are only for the purpose of explaining the principles of the present invention, and cannot be interpreted as limiting the scope of protection of the present invention in any way. Based on the explanation here, any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention, and other specific implementation methods of the present invention that can be associated with by technicians in this field without creative labor, should be included in the scope of protection of the present invention.
