Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical connectors, and in particular to a crimped plug structure. Background Technology
[0002] Electrical connectors are interface devices that enable electrical signal connections between two devices. They typically have connection ports, widely using USB ports. This includes the USB Type-A interface, a traditional USB host port design and one of the easiest devices to identify, such as the ports on a computer for plugging in a mouse, keyboard, or USB flash drive. Each USB connection consists of the host device's port, the connecting cable, and the receiver device. The USB Type-A interface supports USB 2.0, USB 3.1 Gen 1, and USB 3.1 Gen 2 data transfer rates.
[0003] The metal contacts inside existing USB Type-A interfaces are usually soldered to the wires outside the casing via flexible connecting wires. However, this soldering method has the potential for defects such as false soldering, poor soldering, and short circuits caused by solder dross, which in turn affect the normal transmission of electrical signals inside the interface. This means that the USB Type-A interface has poor stability and voltage resistance. At the same time, using solder wires for connection also means that the length and size of the product plug cannot be further reduced.
[0004] Therefore, this utility model proposes a riveted plug structure. Utility Model Content
[0005] The utility model of this invention provides a crimped plug structure, which mainly solves the problem that the metal plate inside the existing USB Type-A interface is usually soldered to the wire outside the shell through a flexible connecting wire. However, this soldering method has the potential for defects such as false soldering, poor soldering, and short circuits caused by solder dross, which in turn affects the normal transmission of electrical signals inside the interface. That is, the stability and voltage resistance of the USB Type-A interface are poor. At the same time, the use of wire bonding also makes it impossible to further reduce the length and volume of the plug part of the product.
[0006] This utility model proposes a riveted plug structure, including:
[0007] The casing has a power cord connected to one end.
[0008] The main body is built into the housing; the main body has a flat structure, and one end face of the main body abuts against the end face of the housing; the end face of the main body away from the housing is a contact surface;
[0009] A terminal block is disposed at one end of the main body and facing the power line; the terminal block is electrically connected to the contact surface of the main body; the terminal block is configured with a stepped open structure with bends on both sides.
[0010] Preferably, the main body is in the shape of a number 7, and the end face perpendicular to the contact surface is provided with a through hole through which the wiring terminal passes; the wiring terminal passes through the through hole and is stacked on the contact surface of the main body;
[0011] One end of the terminal block is strip-shaped, and the other end is a stepped open structure with bends on both sides; the strip-shaped end of the terminal block is stacked on the contact surface of the main body, and the stepped open structure with bends on both sides is located on the outside of the main body.
[0012] Preferably, the strip-shaped end of the terminal block and the stepped open structure with bends on both sides are perpendicular to each other, and the strip-shaped end is centrally connected to the center of the stepped open structure with bends on both sides.
[0013] Preferably, the contact surface on the main body is provided with:
[0014] The groove has one end connected to the through hole and the other end is a blind hole; the length direction of the groove is the same as the length direction of the main body.
[0015] The strip-shaped end of the terminal block is positioned within the groove.
[0016] Preferably, the main body is provided with a number of through holes, and all the through holes are arranged in a row on the same horizontal plane;
[0017] The contact surface of the main body is provided with a number of grooves equal to the number of through holes, and one end of any groove is connected to any of the through holes;
[0018] The number of terminals is equal to the number of through holes, and each terminal passes through any of the through holes and is disposed in the corresponding groove.
[0019] Preferably, the contact surface of the main body is further provided with:
[0020] A retaining edge is protruding from the edge of the contact surface, and the length direction of the retaining edge is the same as the length direction of the groove; the free end of the retaining edge is inclined downward and connected to the edge of the contact surface.
[0021] Preferably, the shell is formed by wrapping a sheet-like structure with serrated edges, and the serrated edges are interlocked.
[0022] Preferably, the end face of the housing with the serrated edge is abutted against the end face of the main body.
[0023] As can be seen from the above, the following beneficial effects can be obtained by applying the technical solution provided by this utility model:
[0024] First, the riveted plug structure proposed in this utility model uses a stepped open structure with bends on both sides of the terminal block to connect the wire to the terminal block. This allows the wire to be firmly connected to the terminal block by riveting, which improves the stability of electrical signal transmission within the plug structure and enhances the overall anti-interference capability of the plug structure.
[0025] Secondly, the plug structure proposed in this utility model connects the power cord by riveting and deforming its ends, which can shorten the overall length of the plug structure and reduce the volume of the plug.
[0026] Third, the end structure of the wiring terminal on the riveted plug structure proposed in this utility model not only provides a fixed wire for the riveted connection power cord, but also limits the penetration ratio between the wiring terminal and the through hole, thereby effectively realizing the smooth assembly of the plug structure and improving the product yield.
[0027] Fourth, the shell of the riveted plug structure proposed in this utility model adopts a sheet structure, which can effectively reduce the product's volume. At the same time, the heat dissipation holes help dissipate heat from the terminals and connectors under electrical connection, reduce the product's operating temperature, and extend the product's service life.

[0049] More specifically, a retaining edge 23 is also provided on the contact surface of the main body 20; the retaining edge 23 protrudes from the edge of the contact surface, and the length direction of the retaining edge 23 is the same as the length direction of the groove 22; the free end of the retaining edge 23 is inclined downward to connect to the edge of the contact surface.
[0050] Preferably, in this embodiment, the retaining edge 23 is an integrally formed structure on the main body 20.
[0051] Preferably, in this embodiment, the height of the retaining edge 23 is the same as the height of the wiring terminal 30 located in the groove 22.
