Description

Technical Field

[0001] The utility model relates to the technical field of connectors, and more particularly to a plug and a high-voltage connector with a simple structure. Background Art

[0002] With the widespread adoption of new energy electric vehicles and high-voltage power equipment, the demand for high-voltage connector reliability is increasing. As a critical component in power transmission, the stability and durability of high-voltage connector connections are directly related to the safe operation of the entire system. To enhance connection reliability, the terminals on traditional high-voltage connector plugs often feature complex clamping structures. These clamping structures, typically composed of multiple components, are designed to ensure a secure connection by increasing contact area and tightening force.

[0003] However, this multi-component structure has some drawbacks. First, the complex structure increases the difficulty and cost of manufacturing, requiring high-precision processing equipment and strict assembly processes. Second, the connections between the multiple components become potential failure points, susceptible to environmental factors (such as vibration and temperature changes) and long-term wear and tear, causing the connections to loosen or become damaged, thereby affecting the normal operation of the equipment.

[0004] The above shortcomings need to be improved. Summary of the Invention

[0005] In order to solve or alleviate the problems of the existing socket having many components, a relatively complex structure, being inconvenient to manufacture, and having many potential safety hazards, the utility model provides a plug and a high-voltage connector with a simple structure.

[0006] The technical solution of this utility model is as follows:

[0011] Furthermore, the front sections of the first elastic member and the second elastic member are respectively provided with bends close to each other, and the front ends of the first elastic member and the second elastic member are provided with rounded corners.

[0012] Furthermore, an inserting interface is provided on the shell, and the distance between the front ends of the first elastic member and the second elastic member is greater than the width of the inserting interface.

[0013] Furthermore, a pad for placing a circuit board is provided on one side of the exterior of the shell.

[0014] Furthermore, positioning posts are provided between the pads, and positioning holes engaged with the positioning posts are provided on the circuit board.

[0015] Furthermore, the housing is provided with a plurality of mutually independent accommodating grooves, and the accommodating grooves correspond one-to-one to the connecting terminals.

[0027] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0029] like Figures 1 to 3 As shown, a plug with a simple structure described in one embodiment of the utility model includes a shell 1, and a plurality of connecting terminals 2 are arranged in the shell 1. The connecting terminals 2 include a main body 201, and a clamping portion 202 connected to the socket terminal 401 is provided at one end of the main body 201, and a connecting portion 203 connected to the circuit board 3 is provided at the other end of the main body 201. The connecting terminals 2 are bent into one piece.

[0030] During production, high-strength, highly conductive metal materials, such as copper, copper alloys, aluminum, or aluminum alloys, are selected as the raw materials for the connecting terminals 2. These materials not only meet electrical performance requirements but also have good processing properties. Using stamping or bending equipment, the raw materials are directly processed into the final shape of the connecting terminals 2. That is, the main body 201, clamping portion 202, and connecting portion 203 of the connecting terminal 2 are formed by integral bending, eliminating the need for additional welding or assembly steps. This simplifies the production process, improves production efficiency, and reduces potential failure points caused by multi-component connections. The formed connecting terminals 2 require surface treatment, such as tinning, gold plating, or spraying an insulating layer, to improve their corrosion resistance, conductivity, and insulation properties. The treated connecting terminals 2 are installed in the plug housing 1, ensuring that each connecting terminal 2 is firmly fixed in the predetermined position, and the connecting portion 203 is welded to the circuit board 3.

[0031] In this embodiment, the connecting terminal 2 is formed by bending, reducing the number of components and simplifying the plug structure. This facilitates automated production, improves production efficiency, shortens production cycles, and reduces production complexity and costs. Because the connecting terminal 2 is integrally formed, it eliminates the gaps and looseness that occur in traditional multi-component connections, improving the stability and reliability of the connection while also reducing the risk of failure due to damage to the connection.

[0032] like Figure 2 and Figure 3 As shown, in a preferred embodiment, the connecting portion 203 is a plug pin, and the circuit board 3 is provided with a plug hole 301 that is plugged into and matched with the plug pin.

[0033] In this embodiment, the mating of the plug pins and sockets 301 facilitates the connection between the connector terminal 2 and the circuit board 3, simplifies the assembly process, improves assembly efficiency, and facilitates automated production. A tight electrical connection is achieved between the plug pins and sockets 301, ensuring stable signal or current transmission, reducing the risk of poor contact or short circuits, and improving the reliability of the electrical connection. Once inserted into sockets 301, the plug pins create a mechanical locking effect, which stabilizes the position of the connector terminal 2 on the circuit board 3. This helps resist external environmental factors such as vibration and shock, ensuring the long-term stable operation of the connector in harsh operating environments.

[0034] In practical applications, the connecting portion 203 may be a soldering pin, and the circuit board 3 only has solder pads corresponding to the soldering pins.

[0035] In this embodiment, providing pads corresponding to the solder pins on the circuit board 3 can simplify the wiring design without having to consider the position occupied by the plug hole 301, and helps save space on the circuit board 3 and improve the compactness and aesthetics of the layout.

[0036] like Figure 2and Figure 5 As shown, in a preferred embodiment, a card slot 204 is provided on the main body 201 , and a buckle 101 engaged with the card slot 204 is provided on the inner wall of the shell 1 .

[0037] In this embodiment, the slot 204 cooperates with the buckle 101 to ensure a secure connection between the main body 201 and the housing 1. No additional connectors are required, resulting in a compact structure that helps reduce the overall volume and weight of the product and makes the product look neater and more aesthetically pleasing. The design of the slot 204 and the buckle 101 simplifies the assembly process of the main body 201 and the housing 1. No complex tools or specialized skills are required. Simply align the main body 201 with the housing 1 and gently press. The buckle 101 automatically snaps into the slot 204 to complete the assembly. After the main body 201 and the housing 1 are assembled, the buckle 101 snaps into the slot 204, forming a stable mechanical lock that can withstand external shocks, vibrations, etc., ensuring a stable connection between the main body 201 and the housing 1, and helping to improve the durability of the product and extend its service life.

[0038] like Figure 2 As shown, in a preferred embodiment, the clamping portion 202 includes a first clamping jaw 205 and a second clamping jaw 206 arranged opposite to each other, the first clamping jaw 205 is provided with multiple first elastic members 207, and the second clamping jaw 206 is provided with second elastic members 208 corresponding to the first elastic members 207 one by one.

[0039] The first elastic member 207 and the second elastic member 208 are respectively provided with bends 209 close to each other at their front ends. The first elastic member 207 and the second elastic member 208 are provided with rounded corners 210 at their front ends.

[0040] The housing 1 is provided with an inserting port 102 , and the distance between the front ends of the first elastic member 207 and the second elastic member 208 is greater than the width of the inserting port 102 .

[0041] The first clamping jaw 205 and the second clamping jaw 206 are respectively equipped with multiple first elastic members 207 and second elastic members 208, so that the clamping portion 202 can exhibit good adaptive deformation ability when clamping the socket terminal 401. When dealing with the socket terminal 401 with errors in size and shape, or due to slight deviations during the installation process, the elastic members can automatically adjust to ensure stable contact between the clamping portion 202 and the socket terminal 401, thereby improving the reliability of the electrical connection and reducing safety issues such as energy loss and heat generation caused by poor contact.

[0042] The arrangement of multiple first elastic members 207 and second elastic members 208 provides multiple redundant connection guarantees. Even if the performance of one or a few elastic members degrades due to prolonged use or environmental influences, the remaining elastic members can still maintain a stable connection, enhancing the stability and reliability of the connection and preventing the risk of overall connection failure due to a single point of failure.

[0043] The bend 209 and rounded corners 210 at the front ends of the first and second elastic members 207 and 208 facilitate the connection of the clamping portion 202 with the receptacle terminal 401 during the clamping process. The narrow spacing at the bend 209 facilitates secure clamping of the receptacle terminal 401, while the wider spacing at the front reduces interference during docking and improves docking efficiency. Furthermore, the insertion port 102 provided on the housing 1 not only provides insulation protection for the connecting terminal 2, enhancing safety during use, but also guides the insertion direction of the receptacle terminal 401, ensuring accurate and reliable docking.

[0044] like Figure 2 As shown, in a preferred embodiment, a plurality of pads 103 for placing the circuit board 3 are provided on one side of the exterior of the housing 1 .

[0045] Positioning posts 104 are provided between the pads 103 , and positioning holes 302 engaged with the positioning posts 104 are provided on the circuit board 3 .

[0046] In this embodiment, the housing 1 supports the circuit board 3 via the backing plate 103. This reduces the contact area, leaving room for heat dissipation and facilitating heat dissipation. Furthermore, it allows for the components and pins on the circuit board 3 to be positioned away from the housing 1. The positioning posts 104 cooperate with the positioning holes 302 on the circuit board 3. When the circuit board 3 is placed on the backing plate 103, the positioning posts 104 snap into the positioning holes 302, positioning the circuit board 3 from multiple directions. This simplifies the installation process of the circuit board 3, improves assembly efficiency, and facilitates the connection between the circuit board 3 and the connection terminals 2. Furthermore, the cooperation between the positioning posts 104 and the positioning holes 302 provides additional fixing force, enhancing the stability of the circuit board 3 within the housing 1, preventing it from loosening due to vibration or impact during operation, improving the vibration resistance of the components and connectors on the circuit board 3, and ensuring that they maintain good operating performance even in harsh environments.

[0047] like Figure 3 As shown, in a preferred embodiment, the housing 1 is provided with a plurality of mutually independent accommodating grooves 105 , and the accommodating grooves 105 correspond to the connecting terminals 2 one by one.

[0048] In this embodiment, the mutually independent receiving grooves 105 provide an isolated environment for the connecting terminals 2, helping to reduce electromagnetic interference or physical collisions between different terminals, thereby improving signal transmission quality and product reliability. Furthermore, the receiving grooves 105 provide a certain degree of protection for the connecting terminals 2, reducing the intrusion of external impurities such as dust and moisture, thereby extending the product's service life.

[0049] like Figures 4 to 7 As shown, a high-voltage connector in one embodiment of the present invention includes a plug and a socket 4, and the plug is the above-mentioned plug with a simple structure.

[0050] In this embodiment, the simple plug structure described above simplifies the overall high-voltage connector structure, reducing manufacturing and assembly complexity and improving production efficiency. Furthermore, the simplified structure reduces the number of components and connection points, thereby reducing potential sources of failure. Furthermore, the plug's stable and reliable connection structure allows the high-voltage connector to withstand high voltages and currents during operation, ensuring a stable and reliable connection and stable transmission of electrical signals.

[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
