Description

Technical Field

[0001] The utility model belongs to the technical field of connectors, and particularly relates to a fish-eye terminal board-end coaxial connector. Background Art

[0002] With the continuous development of new energy vehicles, especially the application of 5G wireless technology to automobiles, the electrification, intelligence, networking, and sharing of automobiles are becoming increasingly popular. Coupled with the continuous innovation of ADAS (Advanced Driver Assistance System) technology, the traditional distributed architecture is difficult to meet the development needs. The domain controller (DCU) integrated architecture based on domains has emerged. After high integration, the use of traditional connectors takes up a large amount of space, and the press-fit fish-eye terminal comes into being. The fish-eye terminal is inserted into the board separately, and the mating ports of the connector are integrally injection-molded on the back cover of the domain controller, greatly reducing the size of the controller.

[0003] Among common connectors, the floating connector is a multi-PIN connector that can only transmit signals within 100 megabits, with a low transmission rate. At the same time, it requires mating connection of male and female connectors, and two board-end connectors and a wire harness are needed, resulting in high usage costs, large space occupation, and cumbersome assembly. After the PCB board is assembled, the connecting wire harness needs to be assembled separately; while for common fish-eye terminal coaxial connectors, both ends need to be welded, and during the reflow soldering process, the connectors are not easy to position and fix. Content of the Utility Model

[0004] The purpose of the utility model is to provide a fish-eye terminal board-end coaxial connector to solve the problems of large space occupation, cumbersome assembly, and difficult fixation of common connectors.

[0005] The utility model realizes the above purpose through the following technical solutions: It includes a fish-eye terminal, an insulator is arranged on the side of the fish-eye terminal, an outer conductor is arranged outside the insulator, and four connection feet are fixedly arranged at one end of the outer conductor.

[0006] Further, the fish-eye terminal includes an insertion head, a fish-eye area, a press-in stress area, and a mating area. The press-in stress area and the mating area are inserted into the insulator and are connected through.

[0007] Further, a limiting circular plate is fixedly arranged at one end of the insulator, an interference boss is fixedly arranged outside the insulator, and both sides of the interference boss are designed as inclined surfaces.

[0008] Further, an insertion round hole is arranged inside the outer conductor, the size of the insertion round hole is the same as that of the insulator, a large-size groove is arranged at one end of the insertion round hole, the size of the groove is the same as that of the limiting circular plate, and the interference boss is clamped into the inner side of the insertion round hole.

[0009] Further, one end of the groove is provided with an outwardly inclined slope.

[0010] Further, the outer conductor is made of brass, with a nickel plating base and then a gold plating on the surface, and the insulator is made of LCP material.

[0011] Beneficial effects: The design of the present utility model is reasonable and has the following beneficial effects:

[0012] 1. In the solution of the present utility model, the fish-eye terminal coaxial board-end connector is a shielded coaxial connector, which is a high-frequency connector. It can transmit high-frequency signals, support a maximum bandwidth of up to 20 GHz, and the theoretical transmission rate can reach 56 Gbps, with a large transmission rate.

[0013] 2. In the solution of the present utility model, one end of the fish-eye terminal coaxial board-end connector uses welding, and the other end uses a non-welded fish-eye terminal. The height of the connector can be minimized to 5 to 10 millimeters, which can greatly save the space between two PCB boards.

[0014] 3. In the solution of the present utility model, after the fish-eye terminal coaxial board-end connector is welded to the PCB board, the fish-eye end can be directly pressed into another PCB board, making the connection and assembly convenient. Description of the Drawings

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0022] Combined with Figures 1 to 4A kind of coaxial connector at the end of a fish-eye terminal board shown, including a fish-eye terminal 1, with an insulator 2 provided on the side of the fish-eye terminal 1, an outer conductor 3 provided outside the insulator 2, and four connection pins 4 fixedly provided at one end of the outer conductor 3.

[0023] Among them, the fish-eye terminal 1 includes a guiding area 11, a fish-eye area 12, a pressing force receiving area 13 and an assembling area 14. The insulator 2 uses over-molding to wrap part of the pressing force receiving area 13 and the assembling area 14.

[0024] One end of the insulator 2 is fixedly provided with a limiting boss 21, and an interference boss 22 is fixedly provided outside the insulator 2. Both sides of the interference boss 22 are designed with inclined surfaces. The limiting boss 21 limits the position of the insulator 2 inside the outer conductor 3, and the inclined surfaces facilitate the interference boss 22 to be snapped into the insertion round hole 31.

[0025] An insertion round hole 31 is provided inside the outer conductor 3. The size of the insertion round hole 31 is the same as that of the insulator 2. One end of the insertion round hole 31 is provided with a large-sized groove 32. The size of the groove 32 is the same as that of the limiting boss 21. The size of the interference boss 22 is larger than the inner hole 31 of the outer conductor. When the insulator is inserted into the outer conductor, the interference boss 22 is in interference with the inner hole 31 of the outer conductor, thereby generating a holding force;

[0026] One end of the groove 32 is provided with an outward-inclined inclined surface to facilitate the insertion and installation of the insulator 2.

[0027] The outer conductor 3 is made of brass, with nickel plating on the surface as a base and then gold plating. The insulator 2 is made of LCP material. The outer conductor 3 is used to install the insulator 2, which is the shell of the connector and has a shielding effect. The insulator 2 is the insulating layer between the outer conductor 3 and the fish-eye terminal 1 and has an insulating effect.

[0028] Working principle: When the utility model is in use, the insulator 2 uses over-molding to wrap the force area 13 and the assembling area 14 of the terminal 1, and then inserts the insulator 2 into the round hole 31 of the outer conductor. The interference boss 22 is snapped into the round hole 31 of the outer conductor for fixation;

[0029] Product use: First, weld the connection pin end of the product to the PCB board, and then press-fit the insertion head 11 and the fish-eye area 12 of the fish-eye terminal 1 into another PCB board for electrical connection.
