Description
Technical Field
[0001] This utility model relates to the field of connector connection, and more specifically, to a protrusion and concave surface mating positioning structure and connector. Background Technology
[0002] Connectors are core components in modern electronic devices, electrical systems, and communication networks, enabling separable connections between components / devices. Their main function is to achieve efficient transmission of power, signals, or data through mechanical and electrical / signal coupling, while also supporting rapid installation, disassembly, and maintenance. As a "bridge connecting the world," connectors are widely used in consumer electronics, automotive, industrial, aerospace, and medical fields, and are key components ensuring the reliable operation of systems.
[0003] Existing connectors typically use a protrusion and concave surface mating structure for fitting during the mating process. However, when existing protrusions and concave surfaces are mated, the rigid protrusions and concave surfaces are in line contact or small-surface contact. During mating, they are easily affected by tilting forces and shift, leading to poor contact or local overpressure. Furthermore, the geometric abrupt change at the root of the protrusion and the edge of the concave surface causes stress concentration, which easily causes wear and reduces the service life of the protrusions and concave surfaces. Utility Model Content
[0004] One objective of this invention is to provide a new technical solution for a protrusion and concave surface mating positioning structure and connector.
[0005] According to a first aspect of this utility model, a protrusion-concave surface mating and positioning structure and connector are provided, including: a board-end connector and a wire-end connector. The board-end connector and the wire-end connector are provided with a protrusion-concave surface mating and positioning mechanism. The protrusion-concave surface mating and positioning mechanism includes a board-end mounting seat, which is mounted on the board-end connector. A board-end protrusion is fixedly arranged on the upper end of the board-end mounting seat. A wire-end mounting seat is mounted on the wire-end connector. A concave surface corresponding to the board-end protrusion is provided on the wire-end mounting seat. The board-end protrusion is provided with multiple inclined surfaces, and the inclined surfaces of the board-end protrusion are transitioned by arc surfaces. The board-end protrusion can be engaged inside the concave surface.
[0006] Preferably, the concave body is bonded to the bottom end of the line end assembly via an adhesive portion.
[0007] Preferably, a positioning plate is fixedly connected to the bottom end of the wire connector, the positioning plate is inserted into the positioning cavity, and the positioning cavity is opened inside the board connector.
[0008] Preferably, the outer walls of the board end mounting base and the wire end mounting base are fixedly connected with fastening blocks, which are engaged in the arc-shaped grooves opened inside the board end connector and the wire end connector.
[0009] A connector includes: a protrusion and concave surface mating structure, a board-end connector, a wire-end connector, a board-end terminal, a wire-end terminal, a board-end mounting base, and a wire-end mounting base. The board-end terminal is disposed inside the board-end connector, and the wire-end terminal is disposed inside the wire-end connector. A modular mechanism is disposed outside the board-end connector and the wire-end connector. The modular mechanism includes a fixing plate, which is fixedly connected to the outer wall of the wire-end connector. A connecting plate is fixedly connected to the bottom end of the fixing plate. A fastening bolt is installed inside the connecting plate, and the fastening bolt is installed inside the board-end connector.
[0010] Preferably, the board end mounting base and the wire end mounting base have fastening grooves inside, and mounting bolts are installed inside the fastening grooves. The mounting bolts are installed inside the board end connector and the wire end connector. The board end mounting base and the outer wall of the board end protrusion are fixedly connected to positioning rods, and the positioning rods are inserted into the positioning grooves opened inside the board end connector and the wire end connector.
[0011] 1. This utility model connects the board-end connector and the wire-end connector through the cooperation of the board-end mounting base, the board-end protrusion, the wire-end mounting base, the concave body, and the adhesive part. The board-end protrusion is inserted into the concave body. The surface of the board-end protrusion is set with multiple inclined surfaces. During insertion, the stepped board-end protrusion guides the connection step by step, reducing positioning deviation. The stepped board-end protrusion also reduces the stress generated at the root of the board-end protrusion, alleviating stress concentration at the root of the board-end protrusion. This results in higher precision during insertion of the protrusion and concave body and improves service life. The concave body itself is made of nitrile rubber elastomer and is fixed to the wire-end connector shell by vulcanization bonding through the adhesive part. Under vibration conditions, the elastic concave body can compensate for gaps through deformation, avoiding rigid collisions, reducing wear on the board-end protrusion and concave body, and improving service life. The stepped board-end protrusion of this protrusion and concave body fitting structure improves the accuracy of connection insertion, avoids wear on the board-end protrusion and concave body, and improves service life, thus enhancing the practicality and functionality of the device.
[0012] 2. This utility model, through the cooperation of fastening grooves, mounting bolts, positioning rods, fixing plates, connecting plates, and fastening bolts, allows the fastening bolts to be simultaneously installed into the connecting plate and the board-end connector after the board-end connector and the wire-end connector are connected. The fastening bolts limit the position of the connecting plate, thereby limiting the position of the wire-end connector, ensuring a tight connection between the board-end connector and the wire-end connector, improving the connection tightness. The board-end mounting base and the wire-end mounting base are modular, facilitating the overall replacement of the wire-end mounting base and concave body on their surfaces. This facilitates disassembly, replacement, maintenance, and adaptation, improving the adaptability and convenience of the device. The connector adopts a modular modular structure, making it easy to disassemble and assemble the various parts, facilitating replacement, maintenance, and adaptation, thus improving the practicality and convenience of the device.

The board end connector 111, wire end connector 112, board end terminal 113 and wire end terminal 114 used in this application are products that can be directly purchased on the market, and their principles and connection methods are existing technologies well known to those skilled in the art.
[0026] Includes: board-end connector 111 and wire-end connector 112. The board-end connector 111 and the wire-end connector 112 are provided with a protrusion and concave surface mating and positioning mechanism 2. The protrusion and concave surface mating and positioning mechanism 2 includes a board-end mounting base 211. The board-end mounting base 211 is mounted on the board-end connector 111. The upper end of the board-end mounting base 211 is fixedly arranged with board-end protrusions 212. The wire-end connector 112 is equipped with a wire-end mounting base 213. The wire-end mounting base 213 is provided with a concave surface 214 corresponding to the board-end protrusions 212. The board-end protrusions 212 are provided with multiple inclined surfaces. The inclined surfaces of the board-end protrusions 212 are transitioned by arc surfaces. The board-end protrusions 212 can be locked inside the concave surface 214.
[0027] When using this protrusion and concave surface mating structure, the board end connector 111 and the wire end connector 112 are connected, so that the board end protrusion 212 is inserted into the concave surface body 214. The surface of the board end protrusion 212 is set with multiple inclined surfaces. During insertion, the stepped board end protrusion 212 gradually guides the insertion, reducing positioning deviation. In addition, the stepped board end protrusion 212 can reduce the stress generated at the root of the board end protrusion 212. The stress concentration at the root of the board end protrusion 212 is relieved, which makes the insertion accuracy of the protrusion and concave surface mating structure higher and improves the service life.

[0032] Fastening blocks 218 are fixedly connected to the outer walls of the board end mounting base 211 and the wire end mounting base 213. The fastening blocks 218 are engaged in the arc-shaped grooves opened inside the board end connector 111 and the wire end connector 112.
[0033] When the board end mounting base 211 is inserted into the board end connector 111 and the wire end mounting base 213 is inserted into the wire end connector 112, the fastening block 218 can be used for positioning, which facilitates installation and improves the connection tightness.
[0034] A connector includes: a protrusion and concave mating structure, a board-end connector 111, a wire-end connector 112, a board-end terminal 113, and a wire-end terminal 114. The board-end terminal 113 is disposed inside the board-end connector 111, and the wire-end terminal 114 is disposed inside the wire-end connector 112. A modular mechanism 3 is disposed outside the board-end connector 111 and the wire-end connector 112. The modular mechanism 3 includes a fixing plate 314, which is fixedly connected to the outer wall of the wire-end connector 112.

[0035] When using this connector, after the board-end connector 111 and the wire-end connector 112 are connected, the fastening bolt 316 can be installed into the connecting plate 315 and the board-end connector 111 simultaneously. The fastening bolt 316 is used to limit the position of the connecting plate 315, thereby limiting the position of the wire-end connector 112, so that the board-end connector 111 and the wire-end connector 112 are connected and tightened, improving the connection tightness.
[0036] The board end mounting base 211 and the wire end mounting base 213 have fastening grooves 311 inside, and mounting bolts 312 are installed inside the fastening grooves 311. The mounting bolts 312 are installed inside the board end connector 111 and the wire end connector 112. The outer wall of the board end mounting base 211 and the board end protrusion 212 is fixedly connected to the positioning rod 313, which is inserted into the positioning groove inside the board end connector 111 and the wire end connector 112.

[0038] Working principle:
[0039] When using this protrusion and concave surface mating structure, the board end connector 111 and the wire end connector 112 are connected, so that the board end protrusion 212 is inserted into the concave surface 214. The surface of the board end protrusion 212 is set with multiple inclined surfaces. During insertion, the stepped board end protrusion 212 gradually guides the insertion, reducing positioning deviation. In addition, the stepped board end protrusion 212 can reduce the stress generated at the root of the board end protrusion 212. The stress concentration at the root of the board end protrusion 212 is relieved, making the insertion accuracy of the protrusion and concave surface mating structure higher and improving service life. The concave surface 214 itself is a nitrile rubber elastomer, which is fixed to the housing of the wire end connector 112 by vulcanization bonding through the adhesive part 215. Under vibration conditions, the elastic concave surface 214 can avoid rigid collision by deforming to compensate for the gap, thereby reducing the wear of the board end protrusion 212 and the concave surface 214 and improving service life.
[0040] When using this connector, after the board-end connector 111 and the wire-end connector 112 are connected, the fastening bolt 316 can be simultaneously installed into the connecting plate 315 and the board-end connector 111. The fastening bolt 316 is used to limit the position of the connecting plate 315, thereby limiting the position of the wire-end connector 112, so that the board-end connector 111 and the wire-end connector 112 are connected and tightened, improving the connection tightness. The board-end mounting base 211 and the wire-end mounting base 213 are assembled structures, which facilitates the overall replacement of the wire-end mounting base 213 and the concave body 214 on their surfaces, making it convenient to disassemble, replace, and repair, adapt to use, and improve the adaptability and convenience of the device.
