Description

Technical Field

[0001] This utility model relates to an automotive board wire end connector assembly and wire end connector, belonging to the field of automotive connector technology. Background Technology

[0002] Existing automotive board-side and wire-side connectors are widely used in vehicle electrical systems to ensure stable signal and power transmission, but they have some problems in practical applications.

[0003] First, most automotive wire-end connectors can only be inserted into board-end connectors in a single direction. This directional limitation increases the difficulty of use and affects assembly efficiency in scenarios requiring quick connection or blind mating. Second, wire-end connectors typically have a latching structure on top, which, while facilitating operation and disassembly, significantly increases the connector's height, making it difficult to meet the needs of compact vehicle interior designs. Furthermore, existing connector structures often lack symmetry, especially in multi-row terminal designs, where wire-end and board-end mating only supports a single direction, which imposes additional requirements on routing and positioning during wiring. Therefore, existing automotive connectors have issues with space utilization and assembly flexibility, and urgently need improvement. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an automotive board wire end connector assembly and wire end connector to solve the problems of inconvenience in quick connection or blind insertion operation, inefficient space utilization, and overly simplistic connection methods of existing automotive connectors.

[0005] To solve the above-mentioned technical problems, this utility model is implemented using the following technical solution:

[0006] In a first aspect, an automotive board-to-wire connector assembly includes: a board-to-wire connector, a wire-to-wire connector, and a wire harness;

[0007] The wire connector includes a body and multiple terminals housed within the body. A locking structure is installed in the middle of the body, and latches are provided on two side walls of the body, with the latches arranged symmetrically.

[0008] The two side walls of the body of the plate-end connector are provided with recessed structures that cooperate with the latch.

[0009] The wire harness is connected to the terminal through the assembly end of the terminal, and the wire harness is parallelly snapped into the body of the wire connector by the locking structure; both the wire harness and the terminal are arranged in two rows, and the two rows are symmetrically arranged in the vertical direction.

[0010] Furthermore, the terminal has a terminal extension at one end opposite to the assembly end, and the locking structure includes the terminal extension and the terminal snap-fit ​​part; the middle part of the terminal extension is provided with an inclined slope, and the two ends of the inclined slope, the end closest to the lowest horizontal direction, are provided with baffles.

[0011] Furthermore, the angle formed by the inclined slope and the horizontal direction is an acute angle, and the end that is farther from the wire harness assembly end is the lowest end in the horizontal direction.

[0012] Furthermore, the baffle and the terminal extension form a frame structure.

[0013] Furthermore, the terminal latching portion and the terminal extension portion are aligned with the inclined slope to position the wire harness, and the wire is limited by a baffle.

[0014] Furthermore, the terminal latching portion is provided with a slope that conforms to the inclined slope.

[0015] Furthermore, the middle part of the body of the wire connector is provided with a hollow structure, and the locking structure is installed in the middle part of the wire connector through the hollow structure.

[0016] Furthermore, a locking block is installed on the surface of the latch that is far from the body, one end of the latch is connected to the body, and the other end is provided with a pressing block.

[0017] Furthermore, the recessed structure of the board end connector is a groove provided on the inner side wall of the body, the latch block engages with the groove, and the latch pressing block extends out of the body.

[0018] Secondly, a wire-end connector includes a wire-end body and terminals housed within the wire-end body for assembling wire harnesses; a locking structure for locking the wire harness is installed in the middle of the wire-end body, and latches are symmetrically arranged on two side walls of the wire-end body, the latches being capable of cooperating with corresponding recessed structures of a plate-end connector; a terminal extension is provided at the end of the terminal opposite to the assembly end; the locking structure includes the terminal extension and a terminal snap-fit ​​portion, the middle of the terminal extension is provided with an inclined slope, and a baffle is provided at both ends of the inclined slope, the end closest to the lowest horizontal direction; the terminal snap-fit ​​portion abuts against the inclined slope of the terminal extension to position the wire harness, and the baffle limits the wire harness.

[0019] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:

[0020] This application provides an automotive board-end connector assembly. By symmetrically arranging latches on the two side walls of the board-end connector and providing recessed structures on the two side walls of the board-end body that mate with the latches, it solves the problem that traditional connectors only support unidirectional insertion. This enables the board-end connector to be inserted in both directions, significantly improving assembly convenience and efficiency. Simultaneously, the latches are located on the side walls of the board-end body rather than the top, reducing the overall height of the board-end connector and better adapting to the compact space requirements of vehicle interiors. The symmetrical design of the board-end connector allows for more flexible insertion of multiple rows of terminals, reducing restrictions on wiring harness routing and location, further improving assembly flexibility and practicality. This structure offers significant advantages in assembly convenience, space utilization, and symmetry, better meeting the design requirements of modern automotive electrical systems.

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use. Example 1:

[0031] like Figure 1 and Figure 3 As shown, this embodiment provides an automotive board wire end connector assembly, including: board end connector 1, wire end connector 2 and wire harness 3;

[0032] The wire connector 2 includes a wire body 20 and a plurality of terminals 210 housed within the wire body 20. A locking structure 21 is installed in the middle of the wire body 20, and latches 22 are provided on the two side walls of the wire body 20. The latches 22 are arranged symmetrically.

[0033] The two side walls of the plate end body 10 of the plate end connector 1 are provided with recessed structures that cooperate with the latch 22.

[0034] The wire harness 3 is connected to the terminal 210 through the assembly end of the terminal 210, and the wire harness 3 is parallelly snapped into the wire end body 20 of the wire end connector 2 through the locking structure 21; both the wire harness 3 and the terminal 210 are arranged in two rows, and the two rows are symmetrically arranged in the vertical direction, thereby realizing the function of reversible insertion of the connector.

[0035] The connector structure achieves stable engagement between the wire harness 3 and the wire end connector 2 by setting a locking structure 21 in the middle of the wire end connector 2, thereby enhancing the reliability of the connector; the terminal 210 has a terminal extension 211 at one end opposite to the assembly end, and the locking structure 21 includes the terminal extension 211 and the terminal engagement part 212; one end of the terminal extension 211 is engaged with the wire harness 3, and the middle of the terminal extension 211 is provided with an inclined slope 213, and baffles 214 are provided at both ends of the inclined slope 213, with the end closest to the lowest horizontal direction.

[0036] like Figure 4 , Figure 5 and Figure 6As shown, the locking structure 21 includes a terminal extension 211 and a terminal snap-fit ​​212. The terminal extension 211 has an inclined slope 213 at the middle of the end that snaps into the wire harness 3. The design of the high and low slopes at both ends gives the structure the dual functions of self-locking and limiting.

[0037] The angle formed by the inclined slope 213 with the horizontal direction is acute, and the end that is farther from the terminal block of the wire harness 3 is the lowest point in the horizontal direction. The inclined slope 213 forms an acute angle with the horizontal direction, and the lowest point is set at the end that is farther from the terminal block. This design ensures that the wire harness 3 can slide naturally to the snap-fit ​​position during the assembly process, reducing assembly resistance and improving efficiency.

[0038] The baffle 214 and the terminal extension 211 form a frame structure; the lowest point of the inclined slope 213 restricts the further movement of the wire harness 3 through the baffle 214, further enhancing the limiting effect of the wire harness 3 and effectively preventing loosening or displacement; the terminal snap-fit ​​part 212 fits against the inclined slope 213 of the terminal extension 211 to position the wire harness 3, and the baffle 214 limits the wire harness 3; the inclined slope 213 of the terminal extension 211 is a slope that gradually slopes along the direction of the wire harness 3 being assembled and pushed in, and the terminal snap-fit ​​part 212 is set as a strip, and the surface of the terminal snap-fit ​​part 212 is provided with an equal slope that can fit against the inclined slope 213. Since there are multiple wire harnesses 3, multiple slopes are correspondingly provided on the surface of the terminal snap-fit ​​part 212.

[0039] like Figure 6 As shown, the terminal latching part 212 is provided with a slope 215 that fits into the inclined slope 213.

[0040] The middle part of the wire end body 20 of the wire end connector 2 is set with a hollow structure, and the locking structure 21 is installed in the middle part of the wire end connector 2 through the hollow structure.

[0041] A locking block 221 is installed on the surface of the latch 22 that is far from the wire end body 20. One end of the latch 22 is connected to the wire end body 20, and the other end is provided with a pressing block 222.

[0042] like Figure 2 As shown, the recessed structure of the board end connector 1 is a groove 11 provided on the inner side wall of the board end body 10. The latch 221 of the latch 22 engages with the groove 11, and the pressing block 222 of the latch 22 extends out of the board end body 10. Example 2:

[0043] Based on Embodiment 1, a wire end connector is provided, including a wire end body 20 and a terminal 210 housed within the wire end body 20 for assembling a wire harness 3; a locking structure 21 for locking the wire harness 3 is installed in the middle of the wire end body 20, and latches 22 are symmetrically arranged on the two side walls of the wire end body 20, and the latches 22 can cooperate with the corresponding recessed structure of the board end connector 1; a terminal extension 211 is provided at the end of the terminal 210 opposite to the assembly end; the locking structure 21 includes the terminal extension 211 and the terminal snap-fit ​​part 212, and an inclined slope 213 is provided in the middle of the terminal extension 211, and a baffle 214 is provided at both ends of the inclined slope 213 near the lowest horizontal direction; the terminal snap-fit ​​part 212 fits against the inclined slope 213 of the terminal extension 211 to position the wire harness 3, and the baffle (214) limits the wire harness (3).

[0044] When the wire connector 2 is inserted into the plate connector 1, the latch 22 itself is elastic, so there is a certain resistance after insertion until it is locked into the groove 11 inside the plate connector 1. The locking block 221 is limited in the groove 11, and the pressing block 222 extends out of the plate body 10 for pressing operation. Due to the setting of the pressing block 222, the latch 22 provides a limit for the locking of the wire connector 2 and the plate connector 1, thereby preventing over-limiting. When it is necessary to cancel the engagement of the plate connector 1 and the wire connector 2, the latches 22 at both ends of the wire connector 2 need to be squeezed, that is, the pressing block 222 needs to be squeezed, so that the latches 22 deform under the action of the elastic structure, thereby canceling the limitation of the locking block 221 and the groove 11, and thus the wire connector 2 can be pulled out from the plate connector 1.

[0045] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art will understand the specific meaning of the above terms in this application based on the specific circumstances.

[0046] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
