Description

Technical Field

[0001] This application relates to the field of connector technology, and in particular to a board-end connector. Background Technology

[0002] With the continuous development of electronic devices and communication systems, connectors, as crucial components for electrical signal transmission, are widely used in computers, communication equipment, industrial control, automotive electronics, and other fields. Especially in modular circuit board structures, board-end connectors are used to ensure reliable connections between wires and the circuit board, making them a key component in the structural design of electronic devices. Most existing board-end connectors are single-unit structures, fixed in place after installation on the circuit board, making it difficult to expand laterally or modularly according to functional requirements. This results in poor product adaptability, inflexible wiring, and even the need to redesign the circuit board. Furthermore, to save space and improve stability, the client is often placed directly on top of the board-end connector. The board-end connector is designed with a limiting structure for assembly with the client's outer shell. However, during actual insertion and removal, excessive insertion force or an unreasonable support structure can still lead to problems such as loosening of the board-end connector, solder joint cracking, and structural deformation, affecting product stability and lifespan.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0037] The following reference Figures 1 to 8 The board-end connector in the embodiments of this application is described.

[0038] In practical applications, to save space, the client is often placed directly on top of the board-end connector 1, and the top of the board-end connector 1 mates with the client's outer shell groove 21. When the wire-end connector 4 is inserted, the board-end connector 1 can be supported and fixed by the outer shell 2 through the assembly of the retaining plate 14 and the outer shell groove 21, rather than relying solely on the PCB board 3, thus protecting the solder joints between the board-end connector 1 and the PCB board 3. When the insertion force of the wire-end connector 4 is relatively large, the force borne by the retaining plate 14 will also increase. When the force exceeds the bearing capacity of the retaining plate 14, there is a risk of breakage.

[0039] according to Figures 1 to 3 , Figure 5 , Figure 6 As shown, a board-end connector 1 according to an embodiment of this application includes a connector body 11. The connector body 11 has a first side 51 and a second side 52 disposed opposite to each other. The first side 51 is provided with a first connecting structure 12, and the second side 52 is provided with a second connecting structure 13. The first connecting structure 12 and the second connecting structure 13 cooperate to realize detachable splicing connection between multiple board-end connectors, which allows users to adjust the number and arrangement of board-end connectors according to actual needs. The first connecting structure 12 of one board-end connector 1 can be detachably spliced ​​with the second connecting structure 13 of another board-end connector 1, thereby realizing modular assembly. The connector body 11 also has a third side 53 facing the client housing 2. The third side 53 is provided with at least one stop plate 14, which is used to cooperate with the groove 21 of the housing to play the role of installation positioning and structural limitation. The periphery of the baffle plate 14 and the third side 53 are connected by a rounded corner structure, which can improve the structural strength of the baffle plate 14 and prevent the baffle plate 14 from breaking when the line connector 4 is inserted. This effectively alleviates local stress concentration, provides additional support for the board connector 1 when inserting or removing the line connector 4, reduces the stress on the solder joints of the PCB board 3, and improves the overall durability and structural stability.

[0040] In some embodiments, two stop plates 14 are provided, and the two stop plates 14 are symmetrically arranged on both sides of the third side 53.

[0041] according to Figures 1 to 4 , Figure 7 and Figure 8 As shown, in one embodiment of this application, the first connecting structure 12 includes a first slide rail 121 and a first slide groove 122 disposed on the first side surface 51. The first slide rail 121 is a protruding structure, and the first slide groove 122 is a recessed structure. The first slide rail 121 and the first slide groove 122 are arranged parallel and spaced apart. The second connecting structure 13 includes a second slide rail 131 and a second slide groove 132 disposed on the second side surface 52. The second slide rail 131 and the second slide groove 132 have the same structure as the first slide rail 121 and the first slide groove 122, respectively. The second slide rail 131 and the first slide groove 122, and the second slide groove 132 and the first slide rail 121 are matched with each other in terms of structural shape and size, and can be spliced ​​together. In actual assembly operations, the operator can slide the first slide rail 121 of one board-end connector 1 into the second slide groove 132 of the adjacent board-end connector 1. Simultaneously, the second slide rail 131 of the adjacent connector also slides into the first slide groove 122 of the former, forming a double slide rail and double slide groove interlocking connection structure, thereby achieving a stable and reliable assembly connection. Assembly can be completed through sliding contact, ensuring both the structural integrity and dimensional consistency after assembly, and facilitating flexible combination of the board-end connectors 1 according to usage requirements, significantly improving the versatility and ease of use of the board-end connectors 1.

[0042] according to Figures 1 to 3 As shown, in one embodiment of this application, guide protrusions 124 are provided on the outer sides of the first slide rail 121 and the second slide rail 131, and guide grooves 125 that cooperate with the guide protrusions 124 are provided on the inner sides of the first slide groove 122 and the second slide groove 132, respectively. The guide protrusions 124 are convex structures extending along the length of the slide rail and are provided on both sides of the slide rail. The guide grooves 125 are provided on the inner side of the slide groove and are matched with the guide protrusions 124 in size and shape to form a stable sliding fit relationship, thereby structurally limiting the vertical wobbling of the slide rail during the sliding insertion process. During the splicing process of two board end connectors 1, when the slide rail of one board end connector 1 is inserted into the slide groove of another board end connector 1, the guide protrusions 124 on the outer side of the slide rail can naturally align and embed into the guide grooves 125 on the inner wall of the slide groove, thereby realizing automatic registration during the sliding process, so that the slide rail maintains a stable linear motion trajectory in the slide groove, and ensuring the overall alignment accuracy and structural stability of multiple board end connectors 1 after splicing.

[0043] according to Figures 1 to 3As shown, in one embodiment of this application, a first engaging portion 123 is provided between the first slide rail 121 and the first slide groove 122, and a second engaging portion 133 is provided between the second slide rail 131 and the second slide groove 132. The first engaging portion 123 and the second engaging portion 133 achieve a locking connection in opposite directions. During the splicing process of multiple board-end connectors 1, when the slide rails and slide grooves of one board-end connector 1 and another board-end connector 1 are inserted into each other, the first engaging portion 123 of the board-end connector 1 and the second engaging portion 133 of the other board-end connector 1 automatically engage, achieving a stable latching lock, ensuring that the board-end connector 1 will not loosen during use, and significantly improving the connection stability.

[0044] according to Figures 1 to 3 As shown, in one embodiment of this application, the first latching portion 123 is provided with a first inclined surface 126, and the second latching portion 133 is provided with a second inclined surface 134, with the orientation of the first inclined surface 126 opposite to that of the second inclined surface 134. Specifically, the first inclined surface 126 is located at the front end of the first latching portion 123 and has an inclined structure at a certain angle, with the first inclined surface 126 inclined towards the rear of the board connector 1 insertion direction; while the second inclined surface 134 is located at the front end of the second latching portion 133, with the inclination direction of the second inclined surface 134 facing forward of the board connector 1 insertion direction, opposite to the direction of the first inclined surface 126, forming a pair of opposing inclined surface guide structures. The two inclined surfaces are aligned with each other during the splicing process of the board connector 1, playing an initial guiding role. In actual assembly, when one board-end connector 1 is inserted into the groove of an adjacent connector along its slide rail direction, the first inclined surface 126 on the first locking part 123 contacts the second inclined surface 134 on the second locking part 133, forming a guiding engagement. The two inclined surfaces of the two board-end connectors 1 engage and slide guided. After sliding to the predetermined installation position, the first locking part 123 and the second locking part 133 lock and fix together, thereby achieving a stable locking effect, significantly reducing the resistance of assembling the board-end connectors 1, and automatically transitioning before locking and fixing.

[0045] according to Figures 1 to 3 As shown in one embodiment of this application, both the first slide rail 121 and the second slide rail 131 are provided with slide rail grooves 127 on their tops. The slide rail grooves 127 extend along the length of the slide rail and are located in the central area of ​​the top of the slide rail. The slide rail grooves 127 effectively optimize the overall material distribution of the slide rail while ensuring its structural strength, resulting in a more uniform thickness distribution. Simultaneously, during the assembly process of inserting the slide rail into the slide groove, the presence of the slide rail grooves 127 can appropriately reduce the contact area between the slide rail and the slide groove, reducing the frictional resistance of the mating parts, effectively improving sliding smoothness, reducing jamming, and avoiding the risk of structural damage or difficulty in insertion due to excessive assembly resistance.

[0046] according to Figure 2 , Figures 6 to 8 As shown, in one embodiment of this application, the connector body 11 adopts a hollow structure, forming a cavity for mounting the wire connector 4 along the length of the connector body 11. The cavity matches the outer contour of the wire connector 4, enabling smooth insertion and stable fixation of the wire connector 4. Several guide portions 15 are provided on the inner wall of the connector body 11. The guide portions 15 are longitudinally convex ribs extending along the insertion direction of the cavity. The guide portions 15 are adapted to the outer guide groove 42 of the wire connector 4, playing an active guiding role during insertion, allowing the wire connector 4 to slide along a preset path, ensuring the smoothness and consistency of the insertion process. A latching portion 16 is also provided inside the cavity. After the wire connector 4 is inserted into the cavity to a predetermined depth, the latching portion 16 automatically engages with the elastic latching portion 41 provided on the wire connector 4, forming a mechanical latch. Through the coordinated cooperation of the guide portions 15 and the latching portion 16, the guidance and accuracy of the insertion of the wire connector 4 are ensured, as well as the stable locking effect after insertion.

[0047] according to Figures 5 to 8 As shown, in one embodiment of this application, the board-end connector 1 further includes a plurality of first pins 61 and a plurality of second pins 62. The connector body 11 is provided with first sockets 181 and second sockets 182 corresponding to the number of pins. The first sockets 181 and second sockets 182 are arranged horizontally and spaced apart. The first pins 61 are connected to the first sockets 181, and the second pins 62 are connected to the second sockets 182.

[0048] according to Figures 1 to 8 As shown, in one embodiment of this application, the connector body 11 is provided with a fourth side 54 opposite to the third side 53. The fourth side 54 faces the PCB board 3, and at least one positioning part 17 is provided on the fourth side 54. The positioning part 17 is positioned facing the PCB board 3. The positioning part 17 is used to provide auxiliary positioning for the board end connector 1 to be assembled in the PCB board 3, to ensure the alignment accuracy of the assembly, not only to prevent the pins from having poor contact or being damaged due to misalignment, but also to act as a structural buffer element to share the lateral force during the insertion and removal process, thereby improving the stability and reliability of the assembly.

[0049] according to Figure 4As shown in one embodiment of this application, a recess 183 is provided at both the first socket 181 and the second socket 182. A protrusion 63 that mates with the recess 183 is provided on the outer side of the first pin 61 and the second pin 62. The size of the protrusion 63 is slightly smaller than the opening size of the recess 183, so that the protrusion 63 can be engaged in the recess 183 when the pin is inserted into place, forming a mechanical fit. This enhances the connection between the pin and the socket, thereby improving the overall mechanical reliability and long-term stability of the board connector 1.
