Description

Technical Field

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

[0002] A board-end connector is a connector whose one end is fixed to a circuit board. Most automotive products have board-end connectors inside, which are used in conjunction with wire-end connectors to transmit power or signals. A board-end connector generally consists of a connector body and insertion terminals. The insertion terminals are composed of multiple pins arranged in a matrix. During the insertion and removal of the connector, the force applied is not consistent with the length direction of the pins, which can easily cause the pins to become misaligned, affecting the transmission of power or signals.

[0003] Therefore, related technologies typically include an end plate at the opening of the connector body, with a portion of the pins extending beyond the end plate. This ensures data transmission functionality while preventing pin misalignment. However, once the end plate is assembled with the connector body, disassembly is difficult and repair is challenging. Forced disassembly can damage the connector structure at the end of the board. Utility Model Content

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0028] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly.

[0030] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0031] Please refer to Figures 1 to 5 This embodiment provides a board-end connector, including a connector body 1, insertion terminals, and an end cap 3. The connector body 1 has a receiving space 11, a first opening, and a second opening. Both the first and second openings communicate with the receiving space 11. The first opening faces a first direction, and the second opening faces a second direction. The first and second directions are perpendicular to each other. The insertion terminal includes multiple pins 2, which extend along the first direction and are arranged in parallel and spaced apart. The multiple pins 2 are arranged in a matrix and are fixedly installed within the receiving space 11. The pins 2 can pass through the end cap 3 along the first direction and extend out of the receiving space 11. The end cap 3 is used to open or close the first and second openings and is detachably connected to the inner wall of the connector body 1. This configuration, by providing the end cap 3 to open or close the first and second openings and being detachably connected to the inner wall of the connector body 1, protects the insertion terminals while facilitating the assembly and disassembly of the end cap 3 and the connector body 1, avoiding damage to the board-end connector structure caused by violent disassembly and reducing the product damage rate.

[0032] Preferably, the board-end connector is made of plastic.

[0033] Specifically, one end of the pin 2 has a barbed structure with a certain elasticity, so that the pin 2 can be pressed into the pin fixing hole of the connector body and has an interference fit with the pin fixing hole, making it difficult to pull out. The other end of the pin 2 is a PIN, which can extend out of the receiving space 11.

[0034] Alternatively, please refer to Figure 2 and Figure 3 The end cap 3 includes a first cover plate 31 and a second cover plate 32 connected at an angle. The first cover plate 31 can open or close a first opening, and the second cover plate 32 can open or close a second opening. The end cap 3 also includes two connecting plates 33 disposed at the corner of the first cover plate 31 and the second cover plate 32. The two connecting plates 33 are arranged parallel and spaced apart along a third direction. The two connecting plates 33 are detachably connected one-to-one with the two first inner walls 12 of the receiving space 11 that are arranged opposite each other along a third direction. The first direction, the second direction, and the third direction are perpendicular to each other. With this arrangement, the connecting plates 33 are detachably connected to the inner walls of the receiving space 11, which makes the end cap 3 easy to install and remove, facilitating the maintenance of the board-end connector. At the same time, through the design of the connecting plates 33, the structural strength of the end cap 3 at the corner is enhanced, further strengthening the protection of the insertion terminal by the end cap 3 and improving the reliability of the board-end connector.

[0035] Furthermore, the board-end connector also includes two snap-fit ​​pieces 4, each with a slot 121 on one of the two first inner walls 12. The two snap-fit ​​pieces 4 can be snapped into the two slots 121 in a one-to-one correspondence. This allows for the assembly and disassembly of the connector body 1 and end cap 3 without the need for other fasteners, improving the efficiency of the board-end connector assembly and disassembly. Simultaneously, the engagement of the snap-fit ​​pieces 4 with the slots 121 provides a stable connection, ensuring that the end cap 3 will not loosen during use.

[0036] Specifically, please refer to Figure 2 , Figure 3 and Figure 5Both snap-fit ​​pieces 4 have a connecting portion 41 and a protrusion 42. One end of the connecting portion 41 is fixedly connected to the end of the corresponding connecting plate 33 away from the first cover plate 31, and the other end of the connecting portion 41 is fixedly connected to the protrusion 42. The slot 121 extends along the second direction, and the distance from the slot 121 to the first opening is equal to the distance from the protrusion 42 to the first cover plate 31. An external force can drive the connecting portion 41 to move away from the connecting plate 33, so that the two protrusions 42 can be snapped into the slot 121 one by one; or, an external force can drive the connecting portion 41 to move closer to the connecting plate 33, so that the two protrusions 42 can disengage from the corresponding slot 121. It can be understood that the connection between the snap-fit ​​piece 4 and the connecting plate 33 can undergo a certain elastic deformation so that it can deform when an external force is applied and return to its original shape after the external force is released, so that the protrusion 42 can be snapped into or disengaged from the slot 121. With simple external force operation, snap-fit ​​and disassembly can be quickly achieved without the use of tools, which greatly improves the assembly efficiency of the board end connector. The design of the connecting part 41 and the protrusion 42 makes the snap-fit ​​part 4 simple in structure. The reliability of the connection is ensured by the cooperation between the protrusion 42 and the slot 121.

[0037] Optionally, each of the two first inner walls 12 is provided with a first guide groove 122. The first guide groove 122 extends along a first direction, and its outer end communicates with a first opening to form a first opening. The snap-fit ​​member 4 is slidably disposed in the corresponding first guide groove 122, and the snap-fit ​​member 4 can slide out from the first opening of the corresponding first guide groove 122. With this configuration, the first guide groove 122 allows the snap-fit ​​member 4 to be accurately aligned with the snap-fit ​​slot 121, ensuring the precise movement of the snap-fit ​​member 4 during installation and disassembly, and preventing the snap-fit ​​member 4 from shifting or jamming during operation. At the same time, after the snap-fit ​​member 4 is inserted into the first guide groove 122, the connecting part 41 deforms towards the connecting plate 33 under the squeezing force of the groove wall of the first guide groove 122, facilitating the entry of the protrusion 42 into the snap-fit ​​slot 121.

[0038] Alternatively, please refer to Figures 2 to 4The accommodating space 11 also includes a second inner wall 13 disposed opposite to the second opening. The two ends of the second inner wall 13 intersect with the two first inner walls 12 at an angle. A second guide groove 14 is provided at each corner of the second inner wall 13 and the two first inner walls 12. The second guide groove 14 extends along a first direction, and its outer end has a second opening communicating with the first opening. A slider 34 is provided at the end of each of the two connecting plates 33 away from the second cover plate 32. The slider 34 is slidably disposed in the corresponding second guide groove 14 and can slide out from the second opening of the corresponding second guide groove 14. This arrangement allows the second guide groove 14 to further guide the sliding of the connecting plate 33 along the first direction, ensuring precise alignment of the end cover 3 during installation and disassembly, thus improving assembly efficiency. Simultaneously, the second guide groove 14's location at the corner of the second inner wall 13 and the two first inner walls 12 prevents the end plate from loosening along the second or third direction during use of the board-end connector, ensuring the reliability of the board-end connector.

[0039] Optionally, a limiting block 35 is provided at the end of the first cover plate 31 away from the second cover plate 32, and a limiting groove 131 is provided on the second inner wall 13 of the accommodating space 11. The limiting groove 131 extends along a first direction, and its outer end has a third opening that communicates with the first opening. The limiting block 35 is slidably disposed in the limiting groove 131, and the limiting block 35 can slide out from the third opening of the limiting groove 131. With this configuration, the end cover 3 can be disassembled or assembled by sliding the limiting block 35 out of or into the limiting groove 131. The mating structure of the limiting groove 131 and the limiting block 35 is simple, improving the efficiency of disassembly and assembly of the board-end connector and facilitating operation by the user.

[0040] Alternatively, please refer to Figures 2 to 4 The limiting groove 131 is T-shaped. With this configuration, the opening of the limiting groove 131 narrows along the direction from the outside to the inside of the receiving space 11, thus limiting the movement of the limiting block 35 along the first direction and preventing it from sliding out towards the second opening. In other embodiments, the limiting groove 131 can also be in the shape of an inverted triangle or an inverted trapezoid.

[0041] Optionally, please refer to point 1. Figure 3 and Figure 4 The first cover plate 31 is provided with multiple limiting holes 311, through which multiple pins 2 can pass one by one. This arrangement ensures the precise assembly of the pins 2 and prevents the pins 2 from becoming misaligned during assembly or use, which could damage the board connector.

[0042] Optionally, the diameter of the limiting hole 311 gradually decreases along the direction in which the pin 2 passes through the limiting hole 311. This design provides guidance for the pin 2 to pass through the limiting hole 311, reducing the difficulty of alignment during installation. The wider entrance of the pin 2 facilitates insertion, while the narrower protrusion facilitates fixing the pin 2, effectively preventing the pin 2 from becoming skewed or deformed due to vibration or external force during use.

[0043] Please refer to Figures 1 to 5 The assembly principle of the board-end connector provided in this embodiment is as follows:

[0044] When installation is required, align the snap-fit ​​4 with the first opening, the slider 34 with the second opening, and the limiting block 35 with the third opening. Push the end cover 3 in the first direction so that the snap-fit ​​4 slides along the first guide groove 122, the slider 34 slides along the second guide groove 14, and the limiting block 35 slides along the limiting groove 131 until the protrusion 42 snaps into the slot 121, thereby locking the relative position of the connector body 1 and the end cover 3.

[0045] When disassembly is required, an external force is applied in the third direction to move the connecting part 41 toward the connecting plate 33 so that the protrusion 42 disengages from the slot 121. The end cover 3 is pulled away from the connector body 1 in the first direction until the snap-fit ​​4 slides out from the first opening, the slider 34 slides out from the second opening, and the limiting block 35 slides out from the third opening, thus completing the disassembly.

[0046] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
