Description

[0002] The FAKRA board-end connector is a widely used connector component in current automobiles. Its terminals are set within the main body through an insulator.

However, this design has its drawbacks. The retention force between the terminal and the insulator is affected by temperature, and the retention force between the terminal and the insulator decreases in high-temperature environments.

DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of this application.

[0045] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the term "and / or" herein is merely a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent three situations: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " herein, unless otherwise specified, generally indicates that the previous and subsequent associated objects are in an "or" relationship. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more features.

[0046] The embodiment of the present application provides a board-end connector, which includes a main body 1, an insulator 2 and a terminal 3. In order to more clearly explain the technical solution, the following definitions are given. Figure 1 The first direction X, the second direction Z and the third direction Y shown in FIG are perpendicular to each other.

[0047] The main body 1 has a front end side 11 and a rear end side 12 along a first direction X, and an upper end side and a lower end side 15 along a third direction Y. A placement cavity 13 is provided in the main body 1 and passes through the rear end side 12, and the cavity wall of the placement cavity 13 has an extrusion surface 14. The insulator 2 is provided in the placement cavity 13, and the insulator 2 includes a main body portion 21 and a limiting portion 22 connected to the main body portion 21. The main body portion 21 is provided with a receiving cavity 211, and the receiving cavity 211 passes through the end side of the main body portion 21 away from the front end side 11. The terminal 3 is provided in the receiving cavity 211. The extrusion surface 14 squeezes the limiting portion 22 so that the limiting portion 22 bends toward the placement cavity 13 to limit the movement of the terminal 3 relative to the insulator 2 in the direction away from the front end side 11.

[0048] The board-end connector of the embodiment of the present application, by providing a limiting portion 22 on the insulator 2, can cooperate with the barb structure 32 on the terminal 3 to achieve double limiting between the terminal 3 and the insulator 2, thereby effectively increasing the holding force between the terminal 3 and the insulator 2, reducing the risk of the terminal 3 being pulled out, and improving product stability.

[0049] Next, combine Figures 1 to 14 The technical solution of this application is further elaborated.

[0050] The main body 1 is preferably an integrally formed structure made of zinc alloy. The main body 1 has an extension portion 18 and a main body 19 along the first direction X. The extension portion 18 is cylindrical, and its end side away from the main body 19 is the front end side 11 of the main body 1, and the end side of the main body 19 away from the extension portion 18 is the rear end side 12 of the main body 1. The embodiment of the present application will take a four-port board-end connector as an example to illustrate the solution. That is, two groups of extension portions 18 distributed along the second direction Z are provided on one side of the main body 19, and each group includes two extension portions 18 distributed along the third direction Y, such as Figure 6 and Figure 7 As shown. Of course, in a specific implementation, the number of extensions 18 in each group is not limited to two, and can also be one, three or more, so as to meet the design requirements of different port numbers of the board-end connector. The board-end connector also includes a shield 5, which is sleeved on the periphery of the extension 18 and fixedly engaged with the main body 19, as shown. Figures 1 to 5 Since the specific structure of the shield 5 and the arrangement between the shield 5 and the main body 1 can be realized by using existing technologies and are not the focus of protection of this application, they will not be described in detail in this embodiment.

[0051] like Figure 6 and Figure 8 As shown schematically in FIG, the main body 1 is provided with two first placement cavities 131 distributed along the third direction Y and two second placement cavities 132 distributed along the third direction Y. Figures 7 to 10 As shown. The first placement cavity 131 includes a first groove cavity portion 1311 and a first tube cavity portion 1312 that are connected. The first groove cavity portion 1311 is close to and passes through the rear end side 12, and forms two first cavity wall surfaces 1315 spaced apart along the third direction Y in the main body 1, as shown. Figure 6 The first groove cavity portion 1311 extends along the second direction Z and passes through the lower end side 15, as shown. Figure 8 As shown. The first tubular cavity portion 1312 passes through the front end side 11 along the first direction X, that is, passes through the extension portion 18 near the upper end side of the main body 1. The second placement cavity 132 includes a second groove cavity portion 1321 and a second tubular cavity portion 1322 that are connected. The second groove cavity portion 1321 is located on the side of the first groove cavity portion 1311 facing the front end side 11 and is connected to the first groove cavity portion 1311, and forms two second cavity wall surfaces 1323 that are relatively spaced along the third direction Y in the main body 1, as shown. Figure 6 The second groove cavity portion 1321 extends along the second direction Z and passes through the lower end side 15, as shown. Figure 8As shown. The second lumen 1322 is located on the side of the first lumen 1312 facing the lower end 15 and extends along the first direction X through the front end 11, that is, through the extension 18 near the lower end 15 of the main body 1. Of course, in embodiments with other port numbers, the number of first and second cavities 131, 132 will be adjusted accordingly. The lower end 15 of the main body 1 is provided with a positioning post 17, which can be used to cooperate with the positioning hole on the circuit board 6 for positioning.

[0052] The board-end connector includes a first insulator 23 and a long terminal 33. The long terminal 33 is disposed in the accommodating cavity 211 of the first insulator 23. The main body 21 of the first insulator 23 includes a first long insulating portion 231 and a second long insulating portion 232. The first long insulating portion 231 and the second long insulating portion 232 are connected. The first long insulating portion 231 is disposed in the first slot cavity 1311, and the second long insulating portion 232 is inserted into the first tubular cavity 1312. Figure 5 The accommodating cavity 211 penetrates the end of the first long insulating portion 231 away from the upper end side along the second direction Z and penetrates the end of the first long insulating portion 231 away from the front end side 11 along the first direction X in the first long insulating portion 231, and forms two inner wall surfaces 213 distributed along the third direction Y in the first long insulating portion 231, as shown. Figure 11 The accommodating cavity 211 is arranged in the second long insulating portion 232 along the first direction X and passes through the end of the second long insulating portion 232 away from the rear end side 12, as shown in FIG. Figure 5 、 Figure 12 and Figure 13 As shown. The long terminal 33 is L-shaped, having a transverse portion extending along the first direction X and a vertical portion extending along the second direction Z. The transverse portion is arranged in the second long insulating portion 232 and is clamped and limited with the inner wall of the second long insulating portion 232 by the barb structure 32, as shown. Figure 5 and Figure 13 As shown. The vertical portion is arranged in the first long insulating portion 231. A pin 31 is provided at one end of the vertical portion away from the upper end side, and the pin 31 extends out of the first long insulating portion 231 for connecting to the circuit board 6, as shown. Figure 14 As shown. The first insulator 23 is interference-fitted with the inner wall of the first placement cavity 131. Preferably, interference fit structures are provided on both the first long insulating portion 231 and the second long insulating portion 232, such as Figure 3 and Figure 11 As shown in FIG, an interference projection 2121 is provided on the outer wall surface 212 of the first long insulating portion 231 opposite to the first cavity wall surface 1315, and an interference ridge 2321 is provided on the outer wall of the second long insulating portion 232. The first insulator 23 is assembled into the first receiving cavity 131 by press-fitting. Of course, in other embodiments, the interference structure may be provided only on the first long insulating portion 231 or the second long insulating portion 232.

[0053] In a preferred embodiment, the limiting portion 22 is preferably arranged on the side of the vertical portion of the terminal 3 in the third direction Y. Figure 11 In the preferred embodiment shown in , the limiting portion 22 is arranged on one side of the vertical portion of the terminal 3 in the third direction Y. Specifically, a notch is provided on the side wall of the first long insulating portion 231 in the third direction Y, and the notch passes through the end of the first long insulating portion 231 away from the front end side 11. The limiting portion 22 is arranged in the notch, one end of the limiting portion 22 is connected to the first long insulating portion 231, and the other end of the limiting portion 22 extends in the first direction X in a direction away from the front end side 11. Preferably, the first cavity wall surface 1315 of the first placement cavity 131 opposite to the limiting portion 22 is used as the extrusion surface 14, as shown in FIG. Figure 6 and Figure 10 The limiting portion 22 has a pressure surface 221 opposite to the extrusion surface 14, as shown in FIG. Figure 11 As shown. When the limiting portion 22 is not under force, the pressure surface 221 is convex outward relative to the outer wall surface 212 of the first long insulating portion 231 opposite to the extrusion surface 14. As a result, when the first insulator 23 is assembled into the first placement cavity 131, the extrusion surface 14 squeezes the pressure surface 221 of the limiting portion 22, driving the limiting portion 22 to bend toward the first placement cavity 131. The limiting portion 22 is provided with a convex structure 222 on the side away from the extrusion surface 14. When the limiting portion 22 bends toward the first placement cavity 131, the convex structure 222 forms a stop limit on the side of the long terminal 33 away from the front end side 11, as shown. Figure 13 As shown, the long terminal 33 is restricted from moving relative to the first insulator 23 in a direction away from the front end 11. Of course, the above is only a preferred embodiment, and the extrusion surface 14 may not be the first cavity wall 1315. For example, in other embodiments, an extrusion protrusion protruding toward the limiting portion 22 may be provided on the first cavity wall 1315, and the side surface of the extrusion protrusion facing the limiting portion 22 may serve as the extrusion surface 14.

[0054] The convex structure 222 has a surface 223 facing away from the extrusion surface 14. Figure 11In a preferred embodiment, when the limiting portion 22 is not subjected to force, the surface 223 is close to the extrusion surface 14 relative to the inner wall surface 213 of the first long insulating portion 231 opposite to the extrusion surface 14, or the surface 223 is flush with the inner wall surface 213 of the first long insulating portion 231 opposite to the extrusion surface 14. That is, when the limiting portion 22 is not subjected to force, the convex structure 222 does not protrude from the inner wall surface 213 of the first long insulating portion 231 opposite to the extrusion surface 14. In this way, when the long terminal 33 is assembled, the limiting portion 22 will not interfere with the long terminal 33, which will save effort and will not cause wear on the convex structure 222, thereby helping to ensure the effectiveness of the limiting portion 22. In another preferred embodiment, when the limiting portion 22 is not under stress, the surface 223 is away from the extrusion surface 14 relative to the inner wall surface 213 of the first long insulating portion 231 opposite to the extrusion surface 14, that is, when the limiting portion 22 is not under stress, the convex structure 222 protrudes from the inner wall surface 213 of the first long insulating portion 231 opposite to the extrusion surface 14. However, it should be noted that the protrusion here refers to the convex structure 222 slightly protruding from the inner wall surface 213. This is because the present application adopts the method of achieving the clamping connection by bending the limiting portion 22 by squeezing the extrusion surface 14. Therefore, when the limiting portion 22 is not under stress, the convex structure 222 does not need to protrude too far from the inner wall surface 213 to meet the needs. For example, taking the terminal 3 with a thickness of 4.5 mm as an example, it is generally necessary to ensure that the convex structure 222 can clamp at least 1.5 mm of the thickness of the terminal 3 to ensure sufficient holding force. Through the technical solution of the present application, when the limiting portion 22 is not under stress, the protruding structure 222 protrudes only 0.5 mm from the inner wall surface 213, and the remaining 1 mm is achieved by the extrusion surface 14 squeezing the limiting portion 22 to bend. In this way, when assembling the long terminal 33, the interference of the limiting portion 22 on the long terminal 33 can be reduced, so that no large force is generated between the limiting portion 22 and the terminal 3, making installation more labor-saving and protecting the limiting portion 22, preventing the limiting portion 22 from severe wear or failure due to breakage due to excessive stress.

[0055] Of course, the above is only a preferred solution. In specific implementations, the position of the limiting portion 22 is not limited to one side of the vertical portion of the terminal 3 in the third direction Y. In other embodiments, the limiting portion 22 may be provided on both sides of the vertical portion of the terminal 3 in the third direction Y, or on the side of the vertical portion of the terminal 3 facing away from the lower end side 15 in the second direction Z. Moreover, the latching protrusion 222 is not limited to being engaged with the side of the long terminal 33 facing away from the front end side 11. In other embodiments, a latching groove or a latching hole may be provided on the long terminal 33, and the latching protrusion 222 may be engaged with the latching groove or the latching hole on the long terminal 33.

[0056] The board-end connector also includes a second insulator 24 and a short terminal 34. The short terminal 34 is disposed within the accommodating cavity 211 of the second insulator 24. The main body 21 of the second insulator 24 includes a first short insulating portion 241 and a second short insulating portion 242, which are connected. The first short insulating portion 241 is disposed within the second slot cavity 1321, and the second short insulating portion 242 is inserted into the second tubular cavity 1322. The specific structure of the second insulator 24, the specific structure of the short terminal 34, the arrangement of the short terminal 34 within the second insulator 24, and the arrangement of the second insulator 24 within the second placement cavity 132 can be referred to the above description of the long terminal 33 and the first insulator 23, and will not be repeated here.

[0057] In a preferred embodiment, an interference fit convex structure 1313 is preferably provided on the inner side wall of the first tubular cavity portion 1312. The interference fit convex structure 1313 and the second long insulating portion 232 are interference fit to limit the movement of the first insulator 23 relative to the main body 1 in a direction away from the front end side 11, thereby improving the holding force between the first insulator 23 and the main body 1. Figures 7 to 10 In the preferred embodiment shown, the interference fit structure 1313 has an abutment wall 1314 on the side facing away from the inner sidewall, and the distance between the abutment wall 1314 and the inner sidewall decreases along the first direction X toward the rear end 12. This design facilitates the smooth passage of the second long insulating portion 232 through the interference fit structure 1313 when inserted into the first tubular cavity 1312. The sidewall surface of the interference fit structure 1313 facing the front end 11 forms a stop surface, which can stop the second long insulating portion 232, further improving the holding force between the first long insulating portion 231 and the inner sidewall of the first tubular cavity 1312, reducing the risk of the long terminal 33 being pulled out due to separation between the first insulator 23 and the main body 1, and further improving product stability.

[0058] In a further embodiment, the board-end connector further includes a shielding plate 4, which is disposed between the first long insulating portion 231 and the first short insulating portion 241. Figure 6 and Figure 8 As shown in FIG, a slot 16 is provided in the main body 1 and passes through the lower end side 15. The slot 16 is located between the first slot cavity 1311 and the second slot cavity 1321. The slot 16 is connected to the first slot cavity 1311 and the second slot cavity 1321 respectively. The shielding plate 4 is inserted into the slot 16. The end of the shielding plate 4 facing away from the upper end side is provided with a pin 41, which can be plugged into the circuit board 6. Figure 3 and Figure 14 In a preferred embodiment, the dimension of the slot 16 in the first direction X increases gradually along the second direction Z in a direction away from the upper end side, that is, the slot width of the slot 16 increases gradually from the slot bottom to the slot opening, as shown in FIG. Figure 8As shown, such a design can make it easier to insert and install the shielding plate 4.

[0059] In a preferred embodiment, a stop protrusion structure 2411 is provided on the side of the first short insulating portion 241 facing the shielding plate 4. The stop protrusion structure 2411 extends toward the direction close to the shielding plate 4. Figure 5 As shown, the stop protrusion structure 2411 can cooperate with the shielding plate 4 to limit the second insulator 24 outside the short terminal 34, reducing the risk of the short terminal 34 being pulled out due to separation between the second insulator 24 and the main body 1, and further improving product stability.

[0060] The above description is only a partial implementation of the embodiments of the present application and does not constitute any form of limitation to the application. The protection scope of the embodiments of the present application is not limited thereto. Any simple modifications, equivalent changes and modifications that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the embodiments of the present application should be covered within the protection scope of the embodiments of the present application.
