Description

Technical Field

[0001] This application relates to the field of connectors, and more particularly to a shorting connector. Background Technology

[0002] Connectors, as a basic and critical electronic component, have the core function of providing a reliable and separable electrical connection interface. They are mainly used to realize the transmission of current and signals between electrical devices, between circuit boards, or between wires and devices / circuit boards.

[0003] In online board-to-board connections, the board-end connector can serve two purposes: it is a female connector with two usage modes—normal connection and two-stage shorting. In normal connection mode, the two metal terminals of the board-end connector correspond one-to-one with the two pins of the male connector and are electrically connected. In two-stage shorting mode, the two conductive parts of the board-end connector are electrically connected, and these two conductive parts then correspond one-to-one with the two pins of the male connector, thus achieving two-stage shorting of the male connector.

[0004] Reference Figure 1 and Figure 2 In related technologies, board-end connectors include a housing 7 and two metal terminals 8 installed in the housing 7. Each metal terminal 8 includes a connecting portion 81 and a crimping portion 82. The connecting portion 81 is used to contact the pins of the male connector, and the crimping portion 82 is used to crimp the wire. The traditional two-stage shorting method involves first crimping both ends of a wire onto the crimping portions 82 of the two metal terminals 8, thus shorting the two metal terminals 8. Then, the board-end connector is inserted into the male connector, causing the pins of the male connector to contact the connecting portion 81 to achieve electrical connection, thereby achieving a two-stage shorting of the male connector. The original two-stage shorting method is complex and inconvenient to operate. Utility Model Content

[0005] To improve the ease of operation of two-stage shorting, this application provides a connector for shorting.

[0006] This application provides a shorting connector, which adopts the following technical solution: A shorting connector includes a housing and a conductive element disposed within the housing. The conductive element has two contact pieces, both of which are electrically connected to the conductive element. The two contact pieces are respectively used to electrically connect to two pins in a male connector. The housing has mounting holes for mounting the conductive element and the contact pieces.

[0007] By adopting the above technical solution, an integrated shorting connector is provided. By integrating two contact pieces onto a conductive element and placing them inside a housing, if shorting is required between the two male terminals, the conductive element with the two contact pieces can be installed into the housing. This avoids the complex process of using two additional wires for crimping in the traditional method, thereby simplifying the installation process, improving operational efficiency, and reducing the risk of failure that may be caused by external wire connections.

[0008] Optionally, the contact piece is formed by bending a conductive element, and the contact piece includes an inclined contact portion. The distance between the contact portion and the conductive element increases along the direction in which the male pin is inserted into the housing. The contact portion is used to abut against the pin in the male pin.

[0009] By adopting the above technical solution and utilizing the inclined design of the contact portion, elastic deformation can be generated when the male pin is inserted, providing continuous and reliable contact pressure to ensure the stability of the electrical connection. At the same time, the inclined structure helps guide the pin to be inserted smoothly, reducing insertion resistance and improving the convenience of user operation and the durability of the connector.

[0010] Optionally, the conductive element has a punched hole, and the conductive element includes an inclined elastic part connected to the hole wall of the punched hole. The inclined direction of the elastic part is the same as the inclined direction of the contact part, and the elastic part is used to abut against the contact piece.

[0011] By adopting the above technical solution, when the male pin contacts the contact piece, the contact piece deforms. At this time, the contact piece contacts the elastic part. Through the contact between the elastic part and the contact piece, the overall elastic support of the contact piece is enhanced, which can ensure the contact reliability after multiple insertions and removals. If the elastic part fails after multiple insertions and removals, the elastic part can play a role, providing continuous and reliable contact pressure, and improving the connector's vibration and shock resistance, further enhancing reliability.

[0012] Optionally, the contact piece may further include an abutting portion extending toward the elastic portion and connected to the contact portion, the abutting portion being used to abut against the elastic portion.

[0013] By adopting the above technical solution, a contact part is provided that abuts against the elastic part. Compared to not having a contact part, this reduces the tilt angle of the elastic part, preventing excessive tilt angle from interfering with the male connector pins. It also reduces the thickness of the contact part, saving materials. Furthermore, it not only improves the rigidity and stability of the contact piece but also ensures that the contact piece does not deform excessively or fail during pin insertion, thereby extending the connector's lifespan and maintaining a stable electrical connection.

[0014] Optionally, the abutting part is formed by bending the contact part, and the connection between the abutting part and the contact part is arc-shaped and used to abut against the pin of the male connector.

[0015] By adopting the above technical solution, the contact part is bent and shaped through the contact part, and the connection is arc-shaped. The arc-shaped structure can reduce stress concentration when the pin is inserted, reduce wear and fatigue risk, and increase the contact area between the contact piece and the male pin. At the same time, the arc surface helps the pin to be smoothly inserted, avoiding scratches or jamming, improving the smoothness and safety of insertion and removal, and making the operation simpler and more reliable.

[0016] Optionally, the mounting hole has a locking block on its wall, and the conductive component has a through hole for inserting the locking block.

[0017] By adopting the above technical solution, a locking block is set on the wall of the mounting hole and a locking hole is opened on the conductive component. Through the cooperation of the locking block and the locking hole, the conductive component is quickly positioned and fixed in the housing, preventing the conductive component from loosening or shifting during use, ensuring accurate alignment of the contact piece and the pin, simplifying the assembly process, and improving the structural stability of the product.

[0018] Optionally, the card block has an inclined sliding surface, and the distance between the sliding surface and the connecting surface of the card block and the hole wall of the mounting hole increases along the direction in which the conductive element is inserted into the mounting hole. The sliding surface is used to slide against the conductive element.

[0019] By adopting the above technical solution, the sliding surface plays a guiding role when the conductive component is inserted into the mounting hole, so that the locking block can smoothly contact the conductive component and lock into the locking hole, reducing resistance and wear during installation, reducing assembly difficulty, improving production efficiency, and avoiding component damage caused by forced installation.

[0020] Optionally, a limiting block is provided on the wall of the mounting hole, and the limiting block is used to abut against the conductive component.

[0021] By adopting the above technical solution, the depth and position of the conductive component in the mounting hole are precisely controlled through the contact between the limiting block and the conductive component, preventing over-insertion or misalignment, ensuring the correct mating of the contact piece and the male pin, improving the consistency and reliability of the connection, and simplifying the quality control process.

[0022] Optionally, an inclined guide surface is formed between the opening surface of the mounting hole and the hole wall of the mounting hole, and the guide surface is used to guide the conductive component to be inserted into the mounting hole.

[0023] By adopting the above technical solution, the guide surface can provide initial guidance for the insertion of conductive components, making it easier to align the conductive components with the mounting holes, reducing adjustment time during installation, and lowering the difficulty of operation. It is particularly suitable for automated production or batch assembly, thus improving overall efficiency.

[0024] Optionally, an inclined guide surface is formed between the opening surface of the mounting hole and the hole wall of the mounting hole, and the guide surface is used to guide the contact piece into the mounting hole.

[0025] By adopting the above technical solution, the guide surface can provide initial guidance for the insertion of the contact piece, making it easier to align the contact piece with the mounting hole, reducing the adjustment time during installation, and lowering the difficulty of operation. It is particularly suitable for automated production or batch assembly, improving overall efficiency, and ensuring that the contact piece is not damaged or bent during the insertion process, thus maintaining the integrity of the contact piece.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. It simplifies the installation process, improves operational efficiency, and reduces the risk of malfunctions caused by external wire connections; 2. The contact between the elastic part and the contact piece enhances the overall elastic support of the contact piece, ensuring contact reliability after multiple insertions and removals.

[0033] The following combination Figures 3-5 This application will be described in further detail.

[0034] This application discloses a connector for shorting. (Refer to...) Figure 3 The shorting connector includes a housing 1 and a conductive element 2, which is installed inside the housing 1. Two contact pieces 3 are fixedly connected to the conductive element 2, each electrically connected to the conductive element 2 and used for electrical connection to the two pins of the male connector. The housing 1 has mounting holes 11 for mounting the conductive element 2 and the contact pieces 3. This structural design achieves integrated mounting of the conductive element 2 and the contact pieces 3, improving the ease of operation for two-stage shorting.

[0035] Reference Figure 3 and Figure 4 The housing 1 is made of plastic. The conductive component 2 can be made of metal materials such as copper or aluminum, which have good conductivity and can ensure stable current transmission. The shape of the conductive component 2 can be designed according to actual needs, such as being plate-shaped or strip-shaped.

[0036] Reference Figure 4 The contact piece 3 is formed by bending the conductive element 2, which can reduce the number of parts, improve production efficiency, and at the same time ensure the stability of the electrical connection between the contact piece 3 and the conductive element 2.

[0037] Reference Figure 3 and Figure 4 The contact piece 3 includes an inclined contact portion 31. The distance between the contact portion 31 and the conductive element 2 increases along the direction in which the male connector's pins are inserted into the housing 1. The contact portion 31 is used to abut against the pins in the male connector. The inclined design of the contact portion 31 allows for elastic deformation when the male connector pins are inserted, providing continuous and reliable contact pressure and ensuring the stability of the electrical connection. For example, the contact portion 31 can be an arc shape at a certain angle, which is beneficial for pin insertion while ensuring contact pressure. The contact portion 31 can also adopt other similar inclined structures, such as a zigzag shape.

[0038] Reference Figure 4 The conductive element 2 has a punched hole 21. The conductive element 2 includes an inclined elastic portion 22 connected to the wall of the punched hole 21. The inclination direction of the elastic portion 22 is the same as that of the contact portion 31. There are two elastic portions 22 and two punched holes 21, each corresponding to one contact piece 3. The elastic portion 22 has a spring-like structure and good elasticity. In actual processing, the elastic portion 22 is directly punched into the conductive element 2, so that the elastic portion 22 and the punched hole 21 share a sidewall.

[0039] When the male connector's pins abut against the contact portion 31, the elastic portion 22 abuts against the contact piece 3. The inclined arrangement of the elastic portion 22 causes the contact piece 3 to deform and abut against the elastic portion 22 after the male connector's pins abut against the contact piece 3, thereby enhancing the overall elastic support of the contact piece 3.

[0040] Reference Figure 4 The contact piece 3 also includes an abutting portion 32 extending toward the elastic portion 22 and connected to the contact portion 31. The abutting portion 32 is used to abut against the elastic portion 22. The abutting portion 32 can reduce the tilt angle of the elastic portion 22, prevent the tilt angle of the elastic portion 22 from being too large and interfering with the male pin, and can also reduce the thickness of the contact portion 31, saving raw materials.

[0041] Reference Figure 4 The contact portion 32 is bent into shape by the contact portion 31, so that the connection between the contact portion 32 and the contact portion 31 is arc-shaped and used to abut against the pin of the male connector. The arc-shaped structure can reduce stress concentration when the pin is inserted, reduce wear and fatigue risk, and increase the contact area between the contact piece 3 and the pin of the male connector.

[0042] Reference Figure 3 A locking block 4 is integrally formed on the wall of the mounting hole 11. A locking hole 23 is provided through the conductive component 2 for inserting the locking block 4. The locking hole 23 is located between the two stamping holes 21. The cooperation between the locking block 4 and the locking hole 23 enables the conductive component 2 to be quickly positioned and fixed in the housing 1, preventing the conductive component 2 from loosening or shifting during use. The locking block 4 can be square, round, or other shapes, and the shape of the locking hole 23 matches the shape of the locking block 4.

[0043] Reference Figure 3 The locking block 4 has an inclined sliding surface 41. The distance between the sliding surface 41 and the connecting surface of the locking block 4 and the wall of the mounting hole 11 increases along the direction in which the conductive element 2 is inserted into the mounting hole 11. The sliding surface 41 is used to slide against the conductive element 2. The inclined design of the sliding surface 41 allows the conductive element 2 to contact the locking block 4 more smoothly and engage with the locking hole 23 when it is inserted into the mounting hole 11, reducing resistance and wear during installation. The sliding surface 41 can be a smooth plane or a curved surface with a certain curvature.

[0044] Reference Figure 4 and Figure 5 A limiting block 5 is integrally formed on the wall of the mounting hole 11. The limiting block 5 is used to abut against the conductive component 2. When the conductive component 2 is inserted into the mounting hole 11, the surface of the conductive component 2 away from the opening surface of the mounting hole 11 abuts against the limiting block 5. The limiting block 5 can precisely control the depth and position of the conductive component 2 in the mounting hole 11, preventing the conductive component 2 from being over-inserted or misaligned. The limiting block 5 can be block-shaped, strip-shaped, etc., and its position and size are designed according to the installation requirements of the conductive component 2.

[0045] Reference Figure 3 An inclined guide surface 12 is formed between the opening surface of the mounting hole 11 and the hole wall of the mounting hole 11. The guide surface 12 is used to guide the conductive component 2 as it is inserted into the mounting hole 11. During the insertion of the conductive component 2 into the mounting hole 11, the distance between the guide surface 12 and the conductive component 2 decreases along the direction of insertion. The guide surface 12 provides initial guidance for the insertion of the conductive component 2, making it easier to align the conductive component 2 with the mounting hole 11 and reducing adjustment time during installation. The guide surface 12 can be an angled surface or an arc surface.

[0046] Reference Figure 3 An inclined guide surface 13 is formed between the opening surface of the mounting hole 11 and the hole wall of the mounting hole 11. The guide surface 13 is used to guide the contact piece 3 into the mounting hole 11. During the insertion of the contact piece 3 into the mounting hole 11, the distance between the guide surface 13 and the contact piece 3 decreases along the direction of insertion. The guide surface 13 provides initial guidance for the insertion of the contact piece 3, making it easier to align the contact piece 3 with the mounting hole 11, reducing adjustment time during installation, and ensuring that the contact piece 3 is not damaged or bent during insertion. The shape of the guide surface 13 is similar to that of the guide surface 12 and can be designed according to the shape and size of the contact piece 3.

[0047] Reference Figure 3 The housing 1 also has an integrally formed buckle 6, and the housing 1 and the male connector are connected by the buckle 6 and the buckle groove on the male connector.

[0048] The assembly principle of a shorting connector according to an embodiment of this application is as follows: first, the conductive element 2 with the contact piece 3 is inserted into the mounting hole 11 (the conductive element 2 and the insertion end of the housing 1 are interference-fitted) until the conductive element 2 abuts against the limiting block 5, and at the same time, the locking block 4 is inserted into the locking hole 23.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
