Detailed Implementation
[0022] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.
[0023] This application provides an RF board-end connector to solve the problems of poor shielding and unstable signal transmission in existing RF connectors. It should be noted that in this application, the direction of the latch relative to the back cover is front, front end, or forward, and the opposite direction is back, rear end, or rearward; the direction of the locking member relative to the outer conductor is up, above, upper side, upper end, top, top tip, or top, and the opposite direction is down, below, lower side, lower end, bottom, bottom tip, or bottom.
[0024] like Figures 1 to 7 The image shows an embodiment of this application: an RF board connector, comprising: an assembly housing 10, an outer conductor 20, a shielding sheet 30, and a contact 40. The assembly housing 10 includes a trapezoidal connecting portion 100. Those skilled in the art can design different shapes according to actual needs, and no limitation is made here. Multiple independent insertion cavities 101 are arranged side-by-side along the length of the connecting portion 100. Each insertion cavity 101 has at least one latch 102 above its front end face for engaging with a mating connector (not shown in the figure). As a preferred embodiment, refer to... Figure 2 Each assembly housing has protruding ridges 104 at different positions on the left and right sides of the front end of the insertion cavity 101, which are used to prevent mis-insertion when connected to the mating connector.
[0025] Reference Figure 4An outer conductor 20 is provided inside the insertion cavity 101. The outer conductor 20 is integrally formed of zinc alloy material and includes a long strip-shaped connecting bridge 200. Multiple insertion parts 201 are arranged side by side along the length of the connecting bridge. Each insertion part has multiple insertion holes 2012. The number of insertion holes 2012 can be set according to actual needs. In this embodiment, each insertion part 201 has four insertion holes 2012. A downwardly recessed slot 2010 is provided in the middle of the upper surface of each insertion part 201. On both sides of the slot 2010, i.e., on both sides of the insertion part 201, long strip-shaped clearance grooves extending from top to bottom are symmetrically provided. Figures 5-6 Each insertion cavity 101 has a strip-shaped slot 103 above its rear end face. A locking member 50 is also installed in each slot 103. In this embodiment, the locking member 50 includes a middle arm 501 and end arms 502 symmetrically arranged on both sides of the middle arm 501. The tops of the middle arm 501 and the end wall 502 are connected to each other. After the locking member 50 is detachably inserted into the slot 103, the middle arm 501 extends downward into the slot hole 2010 and the end arm 502 extends into the clearance groove 2011 to achieve a fixed connection between the assembly housing 10 and the outer conductor 20.
[0026] Reference Figures 6-7 The shielding plate 30 is installed on the rear end face of the connecting part 100. In order to achieve a better shielding effect, the shape of the shielding plate 30 is roughly the same as that of the connecting part. In this embodiment, it is also trapezoidal. Multiple windows 300 corresponding to the insertion cavity are opened on its surface. Each window 300 is provided with a fixed bending part 301 above it. The fixed bending part 301 is inserted into the slot 103 of the assembly housing. At the same time, since the surface of the fixed bending part 301 is provided with a protrusion 3010, the middle arm 501 of the locking member 50 can squeeze the protrusion 3010 to make the shielding plate 30 stably installed on the assembly housing 10, so that the outer conductor 20 and the shielding plate 30 are combined into one by the locking member 50. Then, the grounding part 202 of the lower end of the outer conductor 20 is grounded, which increases the electromagnetic shielding structure design and prevents the controller host components from radiating to the external environment.
[0027] To more stably position the shielding sheet 30 between the outer conductor 20 and the assembly housing 10, combined with Figure 3 and Figure 5Each window of the shielding sheet 30 has at least one side of a rearwardly extending first support portion 302. The surface of the first support portion 302 is provided with a first contact 3020, which abuts against the connecting bridge 200 of the outer conductor 20. The lower end of each window 300 is provided with a plurality of side-by-side bent second support portions 303. The surface of each second support portion 303 is provided with a second contact 3030, which abuts against the insertion portion 201. The locking member 50 and the first support portions 302 and second support portions 303 work together on the outer conductor 20 and the assembly housing 10 to achieve a tight connection between the assembly housing 10 and the outer conductor 20.
[0028] As a preferred embodiment, further reference is made to... Figure 3 The locking element is M-shaped, and the length of the end arm 502 is greater than the length of the middle arm 501.
[0029] Reference Figures 3-4 Inside the socket 2012, there are contacts 40 for connecting with mating connectors. In this embodiment, each mating part has four contacts 40, each contact 40 consisting of a core 401 and a terminal 402. The contacts are arranged in a 2*2 matrix. Below the contacts 40, there is a U-shaped partition 60. Below the mating part 201, there is a fixing groove 203. The partition 60 is inserted upside down between the four contacts 40 and engaged in the fixing groove 203 to stably fix the contacts 40 in the outer conductor 20. Several rear covers 70 are provided behind the contacts 40. Two rear covers 70 are provided on the rear end face of each mating part 201 to seal the contacts 40 in the outer conductor 20. The rear covers 70 can further enhance the shielding performance of the connector and reduce signal interference.
[0030] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0031] The embodiments described above merely illustrate the implementation of this utility model, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
