In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific implementation disclosed below.

[0021] The embodiment of the present application solves the problem of plastic buckle breakage in the connector in the prior art by providing a push lock connector. It should be noted that in the present application, the direction of the first shell relative to the second shell is up, above, upper side, upper end, top, top or top, and the opposite direction is down, below, lower side, lower end, bottom, bottom end or bottom.

[0022] like Figures 1 to 5 As shown, an embodiment of the present application is a push-lock connector, comprising: a first shell 10, a second shell 30, a plastic body 20, a pair of hooks 60, a plurality of terminals 50 and a coaxial cable 40, wherein a receiving cavity 203 is provided in the plastic body 20, the coaxial cable 40 and the plurality of terminals 50 are connected and inserted in the receiving cavity 203, and a pair of hooks 60 are inserted into the inside of the two end arms of the plastic body 20; the first shell 10 and the second shell 30 are mutually buckled at the upper and lower sides of the plastic body 20.

[0023] Reference Figure 5The first shell 10 includes a plane portion 101 and a cantilever portion 100 arranged on the left and right sides of the plane portion 101. The cantilever portion 100 includes a shielding portion 105 and an elastic arm 104 extending from the middle of the shielding portion 105. An elastic snap key 102 is provided at one end of the elastic arm 104. In detail, the elastic snap key 102 is formed by repeatedly bending the end of the elastic arm 104 outward by 90 degrees. In this embodiment, the elastic snap key 102 is folded twice, and can also be folded three times as long as it does not affect the performance; a snap-fitting portion 103 that snaps with the plastic body 20 is provided on the elastic snap key 102. The snap-fitting portion 103 is formed by the top of the outermost pressing surface 1020 of the elastic snap key 102 extending toward the plastic body 20. The snap-fitting portion 103 includes an extension section 1030 and a bending section 1031 bent into the plastic body 20, and the extension section 1030 and the bending section 1031 are L-shaped structures.

[0024] The elastic snap key 102 is set on the first shell 10, and the L-shaped snap part 103 can be directly snapped on the plastic body 20. The installation and disassembly process is simple to operate, and the problem of plastic snap breakage caused by setting the snap on the plastic body 20 can be avoided.

[0025] Reference Figure 2 , Figure 3 and Figure 4 The plastic body 20 includes a main body 201 and a connecting portion 202 arranged on both sides of the main body 201. A downwardly recessed receiving groove 2020 is provided on the upper surface of one end of the connecting portion 202. The bent section 1031 of the buckling portion 103 is buckled in the receiving groove 2020. A supporting portion 2021 and a force-bearing portion 2022 are provided on the side of the connecting portion 202. After the first shell 10 is installed, the shielding portion 105 on the first shell 10 covers the outer side surface of the supporting portion 2021, and the elastic arm 104 covers the outer side surface of the force-bearing portion 2022. When an external force is applied to the outer pressing surface 1020 of the elastic snap key 102, the force is transferred to the elastic arm 104, and the elastic arm 104 applies a force to the force-bearing portion 2022 through the abutting protrusion 2024. As a result, the force-bearing portion 2022 moves inward, and the bent section 1031 on the buckling portion 103 is unlocked from the receiving groove 2020.

[0026] The joint part 202 is provided with a longitudinally extending mounting groove 2023 along the length direction of the force-bearing part 2022. A pair of hook members 60 are respectively installed in the mounting groove 2023. The hook member 60 includes an applied arm 601 and a fixed arm 602. The applied arm 601 is provided with an elastic pressure-bearing part 6010 protruding toward the force-bearing part 2022. A hook part 603 connected to the docking connector is provided at the front end of the applied arm 601. When the force-bearing part 2022 moves inward, it will engage with the elastic pressure-bearing part 6010. 6010 contacts first, and the elastic pressure-bearing portion 6010 drives the entire action-bearing arm 601 to move inward, so that the hook portion 603 at the front end is unlocked from the docking connector; the fixed arm 602 is provided with a stop portion 6020 protruding into the plastic body 20, and the stop portion 6020 is used to be clamped and fixed with the plastic body 20. The fixed arm 602 is also provided with a plurality of contact protrusions (not shown in the figure) that are clamped with the plastic body 20. Such contact protrusions can be set according to needs and are not described here.

[0027] Further references Figure 2-Figure 4 , and also includes a fixing plate 70, which is fixed to one side of the coaxial cable 40 close to the terminal 50, and the fixing plate 70 is located inside the accommodating cavity 203. A plurality of opening slots 2010 are arranged side by side on the plastic body 20, and a portion of the fixing plate 70 is exposed from the opening slots 2010.

[0028] A plurality of first window structures 1010 are arranged side by side on the planar portion 101 of the first shell 10. The first window structures 1010 correspond to the positions of the opening slots 2010. A first stop portion 1011 extending obliquely downward is provided in each first window structure 1010. The first stop portion 1011 abuts against the fixing plate 70 through the opening slots 2010. A pair of locking portions 1012 are also provided on both sides of the side-by-side first window structures 1010. Correspondingly, a plurality of second window structures 301 are arranged side by side on the second shell 30, and each second window structure 301 is provided with a second stop portion 3010 extending obliquely upward, and the second stop portion 3010 abuts against the fixing plate 70, and is clamped on the upper and lower sides by the first stop portion 1011 and the second stop portion 3010 to further fix the position of the internal terminal 50 and the coaxial cable 40; locking holes 302 engaged with the locking portions 1012 are provided on both sides of the side-by-side second window structures 301, and the connection between the first shell 10 and the second shell 30 is achieved by the engagement of the two.

[0029] like Figure 5 As shown, in order to further strengthen the connection strength between the first shell 10 and the plastic body 20, a plurality of plug-in posts 106 bent toward the plastic body 20 may be provided on the first shell 10. The plug-in posts 106 are inserted into the plastic body 20 to strengthen the connection between the two and achieve accurate positioning during installation.
