Description

Technical Field

[0001] The utility model relates to the technical field of electric connectors, in particular to an LVDS line end connector housing, an LVDS line end connector and components thereof. Background Art

[0002] The LVDS line-end connectors on the market today use separate hooks installed on the left and right sides of the plastic body, and a push button is set on the plastic body to realize the left and right movement of the hook to achieve assembly and separation with the board-end connector. However, this split hook will cause the connectors at both ends to lose their locking locks due to reverse installation during installation. In addition, when the hook is installed reversely, its bend is prone to cracking, and the hook head is prone to deflection, which eventually leads to elastic failure and functional failure. In addition, the hook set on the plastic body often has the problem of the push button breaking. There is a gap at the connection of the shell surface at the board end, which requires Mylar to be attached for absorption. This process will increase costs, and the Mylar is easy to fall off during the process, which is prone to absorption problems.

DETAILED DESCRIPTION

[0027] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings. 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.

[0028] The embodiment of the present application solves a series of problems in the prior art, such as reverse installation of connector hooks, complicated installation process, and broken rubber core, by providing an LVDS line-end connector housing, a line-end connector, and components thereof. It should be noted that in the present application, the direction of the board-end connector relative to the line-end connector is front, front end, and front, and the opposite direction is back, rear end, and rear; the direction of the mating housing on the line-end connector relative to the housing is up, above, upper side, upper end, top, top end, or top, and the opposite direction is down, below, lower side, lower end, bottom, bottom end, or bottom.

[0029] like Figures 1 to 8 As shown, this is an embodiment of the present application:

[0030] First, in order to prevent the problem of the split hook being installed upside down, the present embodiment provides an LVDS line end connector housing 20 (hereinafter referred to as the housing), Figure 1 , Figure 2 The present invention is a structural schematic diagram of the shell 20 observed from both front and back perspectives, wherein the shell 20 includes a planar portion 22 and a pair of cantilever portions 21 arranged in the width direction of the planar portion 22, each cantilever portion 21 includes a bottom wall 216 connected to the planar portion 22, a first side wall 212 bent upward along a long side of the bottom wall 216, and a second side wall 213 bent upward along a short side of the bottom wall 216, and an elastic pressing key 210 is provided at the end of the first side wall 212, the elastic pressing key 210 includes an outer pressing surface 2102, and a connecting portion 2103 is bent toward the inner side of the cantilever portion 21 along the bottom end of the outer pressing surface 2102 to form a connecting portion 2103, and a hook portion 211 parallel to the first side wall 212 is bent upward and extended along the connecting portion 2103.

[0031] The elastic pressing key 210, the hook portion 211 and the housing are set as an integral structure, such as Figure 2 F in the figure is the force direction. When the elastic pressing key 210 is pressed and subjected to force, it drives the hook part to extend and retract back and forth through the connecting part 2103. The length of the hook part 211 is greater than the length of the first side wall 212 to facilitate the connection between the hook part 211 and the docking connector.

[0032] An optional implementation is to set an escape space 214 between the bottom wall 216 and the connecting portion 2103. The escape space 214 enables the connecting portion 2103 to have suitable movement space when the elastic pressing key 210 is pressed inward, thereby driving the hook portion 211 to move left and right, thereby making it easier to connect or separate the hook portion 211 from the docking connector.

[0033] The first side wall 212 includes an integrally connected protective arm 2121 and an elastic arm 2120. The elastic pressing key 210 is formed by the end of the elastic arm 2120 being bent outwardly in a serpentine shape, and a force-applying arm 2101 is bent toward the elastic arm 2120 at the side end of the outer pressing surface 2102. In order to apply external force to the hook portion 211 more quickly and better, a force-applying arm 2101 is integrally bent on the elastic pressing key 210, and the external force is transmitted to the elastic arm 2120 through the force-applying arm 2101.

[0037] After the elastic pressing key 210 is stressed by pressing, the elastic stress-bearing arm 101 in the first rubber core 10 is pushed by the abutting protrusion 1010, and the elastic stress-bearing arm 101 further drives the hook part 211 to move left and right. At this time, the elastic stress-bearing arm 101 and the connecting part 2103 play a synergistic role and jointly drive the hook part 211 to move, which is easy to operate.

[0038] like Figure 3 As shown, a fixing plate 60 is also provided on the coaxial cable 40. The fixing plate 60 is fixed to one side of the coaxial cable 40 close to the terminal 50.

[0040] In one implementation mode that can be selected in this embodiment, at least one positioning groove 103 is further provided on the first rubber core 10, and at least one upwardly bent plug post 215 is provided on the cantilever portion 21 of the housing 20, and the plug post 215 is embedded and connected with the positioning groove 103, so as to fix the housing 20 on the first rubber core 10. The matching connection between the plug post 215 and the positioning groove 103 can more accurately control the installation position of the housing 20 without damaging the first rubber core 10.

[0041] like Figure 5 As shown, it is a schematic diagram of the housing 20 to be installed on the first rubber core 10, and the D direction is the installation direction. The elastic pressing key 210 and the hook part 211 are set to form an L-shaped structure and perfectly cooperate with the elastic force-bearing arm 101 of the first rubber core 10, which can not only protect the first rubber core 10 from deformation and breakage, but also realize simplified installation.
