Abstract
Description
Technical Field
[0001] This invention belongs to the technical field of connectors, specifically a connector with a reinforced guiding structure. Background Technology
[0002] With the continuous improvement of transmission speed, the transmission speed and differential module density of existing VPX connectors have gradually become unable to meet application requirements. The structure has evolved from gold finger structure to pin and socket contact form. However, the pin contacts of the differential module are exposed. When the plug and socket are mated, the pin contacts and socket contacts make contact first, and the shell makes contact later. The shell does not play a protective or guiding role during mating. It is easy to misalign during mating, which will make it impossible to complete the mating quickly and accurately. If the mating is misaligned, it will also damage the pin contacts.
[0003] Therefore, how to effectively solve the problem that the housing cannot protect the pins when the plug and socket are inserted, and that the plug and socket are prone to misalignment during insertion, is an urgent technical problem to be solved.
[0004] It should be noted that the above technical information is intended only to enhance the understanding of the overall background technology of the present invention, and should not be regarded as an admission or in any way implying that the above technical information constitutes prior art known to those skilled in the art. Summary of the Invention
[0005] To address the shortcomings of the aforementioned background technology, this invention proposes a connector that solves the problems of the housing failing to protect the pins when the plug and socket are inserted, and the plug and socket easily shifting during insertion.
[0006] The technical solution of this application is as follows: A connector includes a plug assembly and a socket assembly. The bottom surface of the plug assembly and the top surface of the socket assembly are mated together. The plug assembly includes a plug differential module and a plug housing that are mated together by a reinforcing guide structure. The socket assembly includes a detachably connected socket differential module and a socket housing. The height of the socket housing is greater than the height of the socket differential module. The precise guiding mating of the plug differential module and housing in this invention reduces the risk of misalignment and ensures mechanical stability during insertion and removal. The plug and socket assemblies adopt a partially enclosed head design, with the socket housing higher than the contact element, which protects the contact element. When the plug and socket are mated, the housing contacts first, providing guidance. Furthermore, this partially enclosed head design, compared to the socket housing completely enclosing the plug housing, reduces the connector's volume, enabling miniaturized connector design. The compact top-to-bottom mating method saves installation space, is suitable for high-density layouts, and better meets market demands.
[0007] Furthermore, the plug housing includes a plug housing body and a plug pressure plate that are detachably connected by a connector. The plug housing body is provided with the reinforcing guide structure. The plug differential module is plugged into the reinforcing guide structure and blocked by the plug pressure plate.
[0008] Furthermore, the reinforced guiding structure includes several grooves on the inner side of the plug housing, several protrusions on the insulator of the plug differential module, the protrusions being inserted into the grooves, a boss between the grooves and adjacent grooves, and a mating surface on the plug differential module that fits with the boss.
[0009] Furthermore, the first groove includes a narrow groove and a wide groove, and the width of the first mating surface is greater than the width of the narrow groove or greater than half the width of the wide groove.
[0010] Furthermore, the reinforced guiding structure includes several grooves 2 provided on the inner side of the plug housing, a convex surface provided between the groove 2 and the adjacent groove 2, a protrusion 1 provided on the convex surface, several grooves 3 provided on the insulator of the plug differential module, the protrusion 1 inserted into the groove 3, and a mating surface 2 provided on the plug differential module that fits against the convex surface.
[0011] Furthermore, an insulating block is connected to the bottom of the plug differential module, and a second protrusion is provided on the side of the insulating block. A fourth groove is provided on the inner wall of the plug pressure plate to stop the second protrusion.
[0012] Furthermore, the socket housing includes a support frame with snap-fit holes on its inner wall, a second protrusion on the side of the socket differential module that engages with the snap-fit holes, and a baffle to prevent the socket differential module from falling off the bottom surface of the snap-fit holes.
[0013] Furthermore, the side of the socket differential module is provided with an arc surface that is interference-fitted with the support frame to enhance the stability of the connection between the socket differential module and the socket housing, making it less prone to shaking.
[0014] Furthermore, the bottom of the plug pressure plate is provided with a clearance slot for locking onto the support frame. When the plug and socket are inserted, an incomplete seat head is formed, which enhances the stability between the plug assembly and the socket assembly and prevents the plug assembly from shifting along the width direction of the socket assembly.
[0015] Furthermore, the corner of the support frame is provided with an arc-shaped opening for inserting the plug pressure plate. The diameter of the arc-shaped opening is adapted to the thickness of the plug pressure plate, and the plug pressure plate is precisely pressed against the arc-shaped opening to prevent the plug assembly from shifting along the length and width directions of the socket assembly, making it more stable and secure.
[0016] The specific beneficial effects of this invention include: 1. The precise guiding connection between the plug differential module and the housing in this invention reduces the risk of misalignment and ensures mechanical stability during insertion and removal. 2. The plug assembly and socket assembly in this invention adopt a partial socket cover form, with the socket shell higher than the contact element, which can protect the contact element. When the plug and socket are inserted, the shell will make contact first, which plays a guiding role. Moreover, this partial socket cover form reduces the size of the connector compared to the socket shell completely covering the plug shell, which can realize the miniaturization of the connector design. The compact top and bottom docking method saves installation space, is suitable for high-density layout, and can better meet market demands. 3. The mating surface design of the plug and socket ensures a tight fit between the contact terminals, reducing signal loss and temperature rise; based on the mating and interlocking of the differential module and the housing, other optical, radio frequency and other signals can be integrated on the reinforced housing. The plug and socket interlocking enables the integrated transmission of multiple signals. The main application environments are electronics, radar, ships, aviation, aerospace and other fields.

[0026] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.
[0027] Example 1, a connector, as a preferred embodiment, such as Figure 1 As shown, the assembly includes a plug assembly 1 and a socket assembly 2, which are inserted vertically. The bottom surface of the plug assembly 1 and the top surface of the socket assembly 2 are inserted into each other. The plug assembly 1 includes a plug differential module 11 and a plug housing 12 that are inserted and engaged through a reinforcing guide structure. Under the action of the reinforcing guide structure, the plug differential module 11 can be accurately and quickly inserted and engaged with the plug housing 12, which facilitates operation and avoids damage to the pins of the plug differential module 11. The socket assembly 2 includes a detachably connected socket differential module 21 and a socket housing 22. The height of the socket housing 22 is greater than the height of the socket differential module 21. The pin contacts of the socket differential module 21 are exposed. To protect the pin contacts, the height of the socket housing 22 is increased to protect the contacts.
[0028] Based on the above implementation methods, such as Figure 2 As shown, the plug housing 12 includes a plug housing body 13 and a plug pressure plate 14 that are detachably connected by a connector 15.

The insulator of the plug differential module 11 mates with the mating surface 34 on the plug housing 13, fixing the plug differential module 11 in the plug housing 12. The grooves provided on the plug housing 12 serve three purposes: first, to reduce the interference surface and ensure easy assembly even with interference; second, to limit the movement of the plug differential module 11 within the plug housing 12; and third, to facilitate quick insertion and mating.

[0043] Specifically, several plug differential modules 11 are arranged side by side, and each plug differential module 11 has eight grooves 44 evenly spaced on it, such as... Figure 17 As shown in the figure, each plug differential module 11 corresponds to two protrusions 43, such as...

[0047] Based on the above embodiments, the bottom of the plug pressure plate 14 is provided with a clearance slot 61 for locking onto the support frame 51, so that the plug pressure plate 14 and the support frame 51 can be inserted and cooperated. When the plug and socket are inserted, an incomplete seat head is formed, which strengthens the stability between the plug assembly 1 and the socket assembly 2 and prevents the plug assembly 1 from shifting along the width direction of the socket assembly 2.
