Description

A multi-contact wire-to-board connector Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a multi-contact wire-to-board connector. Background Technology

[0002] A wire-to-board connector is a device used to connect circuit boards to wires. It typically consists of two parts: a socket (board connector) with metal pins that insert into a hole in the circuit board, and a plug (wire connector) that holds the wire. When the plug is inserted into the socket, the metal conductive piece contacts the metal slot inside the socket, thus establishing a circuit connection. A multi-contact wire-to-board connector is a type of wire-to-board connector with multiple contacts, which not only ensures the stability and reliability of signal transmission but also increases the number of wires that can be connected.

[0003] In existing wire-to-board connectors, after repeated insertion and removal, the conductive pad on the plug and the metal slot in the socket are prone to loosening or falling off, resulting in poor contact and affecting the reliability and service life of the wire-to-board connector. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that in the prior art, the conductive piece on the plug and the metal slot in the socket are prone to loosening and poor contact after repeated insertion and removal. Therefore, a multi-contact wire-to-board connector is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A multi-contact wire-to-board connector includes a mating plug and a socket, and a pair of first conductive pieces disposed in the socket. One end of each first conductive piece is fixedly provided with a contact spring. The extended surfaces of the free ends of the contact springs intersect, and a connecting groove is formed between the contact springs. A second conductive piece is disposed in the plug, extending into the connecting groove. The top and bottom outer walls of the second conductive piece abut against the contact springs.

[0007] To ensure a reliable connection between the pins and the first conductive sheet, preferably, a guide groove is provided in the socket, and an L-shaped connecting plate is provided in the guide groove. A pin is fixedly provided at one end of the connecting plate extending out of the guide groove, and a U-shaped fixing spring is fixedly provided at the other end of each pair of first conductive sheets. A clamping groove is formed between the fixing springs, and the other end of the connecting plate extends into the clamping groove. The top and bottom outer walls of the connecting plate abut against the fixing springs.

[0008] To further improve the fixing effect between the first conductive sheet and the connecting plate, grooves are provided on the top and bottom end faces of the other end of the connecting plate, and protrusions are fixedly provided on the outer wall of the fixing spring sheet, with the protrusions engaging with the grooves.

[0009] To facilitate the positioning and fixing of the first conductive sheet, a fixing groove is further provided inside the socket, and the first conductive sheet is placed in the fixing groove, with the inner wall of the fixing groove matching the structure of the first conductive sheet.

[0010] Preferably, the socket has a slot, one end of the plug is fixedly provided with a socket, the socket is slidably disposed in the slot, and anti-misalignment blocks are fixedly provided on both sides of the inner wall of the slot. The outer walls at both ends of the socket are provided with sliding grooves corresponding to the anti-misalignment blocks, and slots are provided on both sides of the slot. Elastic plates are fixedly provided on both sides of the plug, and one end of the elastic plate is engaged with the slot.

[0011] Preferably, the other end of the plug has a wiring groove, a conductive plate is fixedly installed in the wiring groove by screws, one end of the second conductive piece extending into the wiring groove is fixedly connected to the conductive plate, and a pressure plate is raised and lowered in the wiring groove.

[0012] Compared with the prior art, this utility model provides a multi-contact wire-to-board connector, which has the following advantages:

[0013] 1. This multi-contact wire-to-board connector, by setting a pair of first conductive pieces with contact springs in the socket, utilizes the connection groove formed between the contact springs with a small opening and a large interior. After the second conductive piece is inserted into the connection groove, the elasticity of the contact springs can ensure a reliable connection between the second conductive piece and the first conductive piece. Furthermore, due to the elasticity of the connection groove, the second conductive piece can still maintain a tight fit with the connection groove after multiple insertions and removals, reducing the possibility of loosening or falling off, and ensuring reliability and stability during use.

[0014] 2. This multi-contact wire-to-board connector has a fixing groove in the socket that matches the shape and structure of the first conductive piece. After the connecting plate is inserted into the fixing groove and the protrusion engages with the groove, the first conductive piece can be fixed in the fixing groove. It is easy to install and remove, and improves maintenance efficiency.

[0015] All parts of this device not described herein are the same as or can be implemented using existing technology. This utility model provides a pair of first conductive pieces with contact springs inside the socket. By utilizing the connecting groove formed between the contact springs, which has a small opening and a large interior, after the second conductive piece is inserted into the connecting groove, the elasticity of the contact springs ensures a reliable connection between the second and first conductive pieces. Furthermore, due to the elasticity of the connecting groove, the second conductive piece can still maintain a tight fit with the connecting groove after multiple insertions and removals, reducing the possibility of loosening or falling off and ensuring reliability and stability during use.

[0023] Example:

[0024] Referring to Figures 1-4, a multi-contact wire-to-board connector includes a mating plug 2 and a socket 1. A second conductive piece 5 is disposed within the plug 2. The second conductive piece 5 extends into a connecting groove, at which point the top and bottom outer walls of the second conductive piece 5 abut against a contact spring 402. The connector also includes a pair of first conductive pieces 4 disposed within the socket 1. Here, multiple sets of the pair of first conductive pieces 4 are equidistantly arranged, preferably fifteen sets. Each first conductive piece 4 consists of a contact spring 402 and a fixing spring 401, which are fixedly connected by a limiting piece 403. Specifically, in one of the first conductive pieces 4… A contact spring 402 is fixedly provided at one end. The extended surfaces of the free ends of a pair of contact springs 402 intersect, and a connecting groove is formed between the contact springs 402. That is to say, the connecting groove is small at the opening and gradually increases in size inside. In order to facilitate the insertion of the second conductive piece 5 into the connecting groove, an outwardly protruding guide plate is fixedly provided at the free end of the contact spring 402. At this time, when the second conductive piece 5 is inserted into the connecting groove, one end of the second conductive piece 5 abuts against the guide plate, which can push the contact spring 402 outward. After being inserted into place, the elastic action of the contact spring 402 can ensure a reliable connection between the second conductive piece 5 and the first conductive piece 4.

[0025] In use, a pair of first conductive pieces 4 with contact springs 402 are provided in the socket 1. Utilizing the connecting groove formed between the contact springs 402 (small opening, large interior), after the second conductive piece 5 is inserted into the connecting groove, the elasticity of the contact springs 402 ensures a reliable connection between the second conductive piece 5 and the first conductive piece 4. Furthermore, due to the elasticity of the connecting groove, the second conductive piece 5 maintains a tight fit with the connecting groove even after multiple insertions and removals, reducing the possibility of loosening or falling off and ensuring reliability and stability during use. By providing a fixing groove 102 in the socket 1 that matches the shape and structure of the first conductive piece 4, the first conductive piece 4 can be fixed in the fixing groove 102 after the connecting plate 3 is inserted into the fixing groove 102 and the protrusion 404 engages with the groove 302. This facilitates easy installation and removal and improves maintenance efficiency.

[0026] Referring to Figures 1-3, a guide groove 106 is formed inside the socket 1. One end of the guide groove 106 is connected to the fixing groove 102. An L-shaped connecting plate 3 is provided inside the guide groove 106. A pin 301 is fixedly provided at one end of the connecting plate 3 extending out of the guide groove 106. The pin 301 is electrically connected to the circuit board. Furthermore, snap-fit ​​plates 105 are fixedly provided at both ends of the socket 1. When the socket 1 is installed on the circuit board, the snap-fit ​​plates 105 engage with the connecting grooves on the circuit board, thereby fixing the socket 1 to the circuit board and improving the usability. Additionally, the other ends of each pair of first conductive sheets 4 are fixedly provided with L-shaped connecting plates 102. The U-shaped fixing spring 401 has a clamping groove formed between a pair of fixing springs 401. The other end of the connecting plate 3 extends into the clamping groove, and the top and bottom outer walls of the connecting plate 3 abut against the fixing springs 401. In use, the fixing springs 401 are fixedly installed on the first conductive sheet 4, and the clamping groove is formed between a pair of fixing springs 401. When the connecting plate 3 is inserted into the clamping groove, the elastic action of the fixing springs 401 can clamp the connecting plate 3, which not only ensures a reliable connection between the connecting plate 3 and the first conductive sheet 4, but also facilitates assembly and disassembly, improving the performance. In addition, grooves 302 are provided on the top and bottom end faces of the other end of the connecting plate 3, and protrusions 404 are fixedly installed on the outer wall of the fixing springs 401. The protrusions 404 are engaged with the grooves 302. That is to say, when the connecting plate 3 is inserted into place, the protrusions 404 and the grooves 302 are engaged, which can further ensure the fixing effect and reduce the occurrence of loosening.

[0027] Referring to Figure 3, a fixing groove 102 is provided in the socket 1. The first conductive sheet 4 is placed in the fixing groove 102, and the inner wall of the fixing groove 102 matches the structure of the first conductive sheet 4. That is, the fixing groove 102 is a contour groove. A limiting piece 403 is fixedly provided on the first conductive sheet 4. The connection between the inner wall of the fixing groove 102 and the slot 101 is in a contracted state. When the connecting plate 3 is inserted into the clamping groove, the first conductive sheet 4 can be fixed in the fixing groove 102 under the action of the limiting piece 403. The fixing effect is reliable, and it is easy to install and remove, making it convenient for replacement and maintenance.

[0028] Referring to Figures 2 and 3, a slot 101 is provided in the socket 1. A plug socket 201 is fixedly provided at one end of the plug 2. The plug socket 201 is slidably placed in the slot 101, and anti-misalignment blocks 103 are fixedly provided on both inner walls of the slot 101. Sliding grooves 204 corresponding to the anti-misalignment blocks 103 are provided on the outer walls of both ends of the plug socket 201. Here, two anti-misalignment blocks 103 are fixedly provided on one side and one on the other side. Two sliding grooves 204 are provided on one end of the plug socket 201 and one on the other end to connect with the anti-misalignment blocks 103. This can prevent the plug 2 from being installed in the wrong direction when connected to the socket 1. This design affects normal use. Slots 104 are provided on both sides of the slot 101, and elastic plates 203 are fixedly installed on both sides of the plug 2. One end of the elastic plate 203 is engaged with the slot 104. During use, by fixing the elastic plates 203 on both sides of the plug 2, after the plug 2 and socket 1 are inserted into place, the end of the elastic plate 203 away from the plug 2 engages with the slot 104, ensuring a reliable connection between the plug 2 and socket 1 and reducing loosening. During disassembly, the elastic plate 203 can be pressed away from the slot 104, at which point the elastic plate 203 disengages from the slot 104, and the plug 2 can then be unplugged.

[0029] Referring to Figures 1-3, a wiring groove 202 is provided at the other end of the plug 2. A conductive plate is fixedly installed in the wiring groove 202 by screws. One end of the second conductive piece 5 extends into the wiring groove 202 and is fixedly connected to the conductive plate. A pressure plate is raised and lowered in the wiring groove 202. A fixing screw is threaded into the plug 2. One end of the fixing screw is rotatably connected to the pressure plate. A knob is fixedly installed at the other end of the fixing screw. In use, by inserting one end of the wire into the wiring groove 202, the knob rotates the fixing screw, driving the pressure plate to clamp the wire, thus fixing the wire between the conductive plate and the pressure plate. Moreover, the wire is electrically connected to the conductive plate, making wire installation and removal convenient, fixing reliable, and improving the performance.
