The first protrusion, the second protrusion, and the third protrusion are distributed alternately in the left-right direction. The seat body has a buckle between the first protrusion and the second protrusion, and between the second protrusion and the third protrusion. The front part of the first protrusion, the second protrusion, and the third protrusion has an opening groove. The first protrusion, the second protrusion, and the third protrusion all have mounting grooves above and below the opening groove. A conductive terminal assembly is installed in the mounting slot, with the pins of the conductive terminal assembly extending into the opening slot; The opening slot is used to place the printed circuit board. The front end of the printed circuit board is provided with a snap-fit ​​structure, which engages with the two buckles to at least restrict the forward and left-right movement of the printed circuit board.

Opening grooves are formed between the first upper protrusion and the first lower protrusion, between the second upper protrusion and the second lower protrusion, and between the third upper protrusion and the third lower protrusion. The front ends of the first upper protrusion and the second upper protrusion are connected, and the front ends of the second upper protrusion and the third upper protrusion are connected.

[0007] In some implementations of this utility model, in conjunction with the above implementations, the buckle has a main body extending in the front-back direction, and a snap-fit ​​part is provided at the top of the main body. The buckle is snapped into the snap-fit ​​structure through the snap-fit ​​part. The main bodies of the two buckles are connected by a pressing part, and the pressing part is located below the second protrusion so as to form a pressing space between the pressing part and the second protrusion.

[0008] In combination with the above implementation methods, in some implementation methods of this utility model, the rear side of the snap-fit ​​portion of each of the snap-fits has an abutment surface extending in the vertical direction, and the snap-fit ​​structure includes two snap-fit ​​grooves spaced apart in the horizontal direction. The snap-fit ​​portion abuts against the inner surface of the corresponding snap-fit ​​groove through the abutment surface to snap-fit ​​with the printed circuit board.

[0009] In some implementations of this utility model, in conjunction with the above implementations, the snap-fit ​​groove is projected along the vertical direction to form a first projection surface, the snap-fit ​​part is projected along the vertical direction to form a second projection surface, the first projection surface completely covers the second projection surface corresponding to the vertical direction, and gaps are formed between the first projection surface and the second projection surface in both the front-back direction and the left-right direction.

[0010] In some implementations of this utility model, in conjunction with the above-described implementations, the mounting groove includes a first mounting groove. The first upper protrusion, the first lower protrusion, the second upper protrusion, the second lower protrusion, the third upper protrusion, and the third lower protrusion are each provided with multiple first mounting grooves spaced apart in the left-right direction. The first mounting grooves of the first upper protrusion and the first lower protrusion correspond one-to-one in the vertical direction. The first mounting grooves of the second upper protrusion and the second lower protrusion also correspond one-to-one in the vertical direction. The first mounting grooves of the third upper protrusion and the third lower protrusion correspond one-to-one in the vertical direction. Each first mounting groove penetrates the base body in the front-back direction and forms a first terminal outlet hole at the rear end of the base body. The conductive terminal assembly includes multiple signal terminals, which are correspondingly installed within the first mounting groove.

[0011] In some implementations of this utility model, in conjunction with the above-described implementations, the mounting groove further includes a second mounting groove. The base body has a plurality of through holes extending in the front-rear direction on the left side of the first mounting groove of the first protrusion and on the right side of the first mounting groove of the third protrusion.

[0015] One of the above technical solutions has at least one of the following advantages or beneficial effects: The connector in this application uses two latches spaced apart in the left-right direction to engage the printed circuit board. On one hand, the latches themselves can at least restrict the forward movement of the printed circuit board; on the other hand, the two latches arranged in the left-right direction can restrict the displacement of the printed circuit board in the left-right direction. Furthermore, the first, second, and third protrusions all limit the movement of the printed circuit board in the vertical direction, and the connector itself can restrict the backward movement of the printed circuit board. This allows the connector as a whole to restrict the movement of the printed circuit board in three dimensions: vertical, front-back, and left-right, improving the stability of the connection between the printed circuit board and the connector.

[0016] The dual-clamp connector in this technical solution achieves a stable connection between the printed circuit board and the connector by setting two clamps, which improves the stability of the connection during use and avoids the printed circuit board from falling off or the electrical connection from being unstable or failing when the equipment is under vibration or shaking, thus preventing the occurrence of malfunctions.

[0019] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0020] In this utility model, when directions (up, down, left, right, front, and back) are described, it is only for the purpose of describing the technical solution of this utility model, and does not indicate or imply that the technical features referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0021] In this utility model, "several" means one or more, "multiple" means two or more, "greater than," "less than," "exceeding," etc. are understood to exclude the stated number; "above," "below," "within," etc. are understood to include the stated number. In the description of this utility model, if "first" or "second" is used, it is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of indicated technical features or the order of the indicated technical features.

[0022] In this utility model, unless otherwise explicitly defined, terms such as "set," "install," and "connect" should be interpreted broadly. For example, they can refer to a direct connection or an indirect connection through an intermediate medium; a fixed connection, a detachable connection, or an integrally formed connection; a mechanical connection, an electrical connection, or a connection capable of mutual communication; or the internal connection of two components or the interaction between two components. Those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model based on the specific content of the technical solution.

[0023] See Figure 1 , Figure 2 , Figure 3 and Figure 5 This utility model provides a dual-buckle connector, including a base 1 and a conductive terminal assembly. The base 1 has a first protrusion 11, a second protrusion 12, and a third protrusion 13 extending forward, which are spaced apart in a left-right direction. The base 1 has latches 2 positioned between the first protrusion 11 and the second protrusion 12, and between the second protrusion 12 and the third protrusion 13. In other words, the front side of the base 1 has two latches 2 spaced apart in a left-right direction, located between the first protrusion 11 and the second protrusion 12, and between the second protrusion 12 and the third protrusion 13, respectively.

[0024] The front of the first protrusion 11, the second protrusion 12, and the third protrusion 13 are all provided with opening slots 14, and the first protrusion 11, the second protrusion 12, and the third protrusion 13 are all provided with mounting slots above and below the opening slots 14, such as... Figure 3 As shown. The conductive terminal assembly is installed in the mounting slot, and the pins of the conductive terminal assembly extend into the opening slot 14.

[0025] The opening slot 14 is used to place the printed circuit board 3, and the pins of the conductive terminal assembly extending into the opening slot 14 are electrically connected to the printed circuit board 3. The front end of the printed circuit board 3 is provided with a snap-fit ​​structure, which snaps into two latches 2 at the front of the base 1 to at least restrict the forward and left-right movement of the printed circuit board 3, thereby improving the stability of the connection between the printed circuit board 3 and the connector.

[0026] Specifically, the printed circuit board 3 is engaged by two latches 2 spaced apart in the left-right direction. On the one hand, the latches 2 themselves can at least restrict the forward movement of the printed circuit board 3; on the other hand, the two latches 2 arranged in the left-right direction can restrict the displacement of the printed circuit board 3 in the left-right direction. In addition, the first protrusion 11, the second protrusion 12, and the third protrusion 13 all play a limiting role in the vertical direction of the printed circuit board 3, and the base 1 itself can restrict the backward movement of the printed circuit board 3. This allows the connector as a whole to restrict the movement of the printed circuit board 3 in three dimensions: vertical, front-back, and left-right, thereby improving the stability of the connection between the printed circuit board 3 and the connector.

[0027] The dual-clamp connector in this technical solution achieves a stable connection between the printed circuit board 3 and the connector by setting two clips 2, which improves the stability of the connection between the two during use and avoids the printed circuit board 3 from falling off easily or the electrical connection from being unstable or failing when the equipment is under vibration or shaking, thus avoiding the occurrence of malfunctions during use.

[0028] Further, see Figures 1 to 5 The first protrusion 11 has a first upper protrusion 111 and a first lower protrusion 112 spaced apart in the vertical direction; the second protrusion 12 has a second upper protrusion 121 and a second lower protrusion 122 spaced apart in the vertical direction; and the third protrusion 13 has a third upper protrusion 131 and a third lower protrusion 132 spaced apart in the vertical direction. Opening grooves 14 are formed between the first upper protrusion 111 and the first lower protrusion 112, between the second upper protrusion 121 and the second lower protrusion 122, and between the third upper protrusion 131 and the third lower protrusion 132.

[0029] The front ends of the first upper protrusion 111 and the second upper protrusion 121 are connected, and the front ends of the second upper protrusion 121 and the third upper protrusion 131 are connected to ensure the stability of the structural connection between the first upper protrusion 111, the second upper protrusion 121 and the third upper protrusion 131.

[0030] See Figure 2 , Figure 3 and Figure 5 In some embodiments, the buckle 2 has a main body 21 extending in the front-rear direction, and a snap-fit ​​portion 22 is provided at the top of the main body 21. The buckle 2 is snapped into the snap-fit ​​structure through the snap-fit ​​portion 22. The main body portions 21 of the two buckles 2 are connected by a pressing portion 23. The pressing portion 23 is located below the second protrusion 12 so as to form a pressing space between it and the second protrusion 12, which facilitates pressing the pressing portion 23.

[0031] Specifically, after pressing the pressing part 23, the latching part 22 of the latch 2 moves downward with the main body 21 and is below the height of the opening slot 14, so that the printed circuit board 3 can be placed into the opening slot 14. Then, the pressing part 23 can be released, and after the pressing part 23 resets, the latching part 22 can be latched with the latching structure.

[0032] It is understood that the snap-fit ​​part 22 and the snap-fit ​​structure can be snapped in the form of a hole structure and a snap-fit ​​block embedded in it, or in the form of two opposite 7-shaped snap-fit ​​blocks, or in the form of an opening slot 14 and a snap-fit ​​block abutting each other, etc. Those skilled in the art can make changes according to the common structures of snap-fit, and no restrictions are imposed here.

[0033] Further, see Figure 2 , Figure 3 and Figure 5 Each latch 2 has a contact surface 24 extending in the vertical direction on the rear side of its latching part 22. The latching structure includes two latching grooves spaced apart in the left-right direction. The latching part 22 abuts against the inner surface of the corresponding latching groove through the contact surface to latch with the printed circuit board 3, thereby preventing the printed circuit board 3 from coming out of the opening groove 14 in the front-back direction.

[0034] Furthermore, see Figure 2 The snap-fit ​​groove is projected along the vertical direction to form a first projection surface, and the snap-fit ​​part 22 is projected along the vertical direction to form a second projection surface. The first projection surface completely covers the second projection surface corresponding to the vertical direction, and there are gaps between the first projection surface and the second projection surface in the front-back direction and the left-right direction, so that the snap-fit ​​part 22 can be inserted into the snap-fit ​​groove, making the installation more convenient and quick.

[0035] See Figure 3 and Figure 5In some embodiments, the mounting groove includes a first mounting groove 15. The first upper protrusion 111, the first lower protrusion 112, the second upper protrusion 121, the second lower protrusion 122, the third upper protrusion 131, and the third lower protrusion 132 are each provided with a plurality of first mounting grooves 15 spaced apart in the left-right direction. The first mounting grooves 15 of the first upper protrusion 111 and the first lower protrusion 112 correspond one-to-one in the vertical direction. The first mounting grooves 15 of the second upper protrusion 121 and the second lower protrusion 122 correspond one-to-one in the vertical direction. The first mounting grooves 15 of the third upper protrusion 131 and the third lower protrusion 132 correspond one-to-one in the vertical direction.

[0036] Each first mounting slot 15 extends through the base body 1 in the front-to-back direction and forms a first terminal outlet hole 16 at the rear end of the base body 1. The conductive terminal assembly includes multiple signal terminals 41, which are correspondingly installed in the first mounting slot 15. After the signal terminal 41 is connected to the signal line, the signal line can extend out of the base body 1 through the first terminal outlet hole 16, realizing the function of the signal line extending out of the connector in a straight line.

[0037] Further, see also Figures 3 to 5 The mounting slot also includes a second mounting slot 17. The base 1 has several through holes 18 extending in the front-to-back direction on the left side of the first mounting slot 15 of the first protrusion 11 and the right side of the first mounting slot 15 of the third protrusion 13. The through holes 18 form second mounting slots 17 in the first upper protrusion 111, the first lower protrusion 112, the third upper protrusion 131, and the third lower protrusion 132, respectively. The conductive terminal assembly also includes multiple power terminals 42, which are correspondingly installed in the through holes 18. The first and second pins of the power terminals 42 are correspondingly installed in the second mounting slots 17 that communicate with the through holes 18 and extend to the opening slot 14 for electrical connection with the printed circuit board 3. After the power terminals 42 are connected to the power cord, the power cord can extend out of the base 1 through the through holes 18, realizing the function of the power cord extending out of the connector in a straight line.

[0038] Furthermore, see Figures 1 to 5 The top rear side of the base 1 is provided with a second terminal outlet hole 43 that corresponds to and passes through each of the first mounting slots 15 and through holes 18. The rear side of the base 1 is provided with a mounting cover 5 for covering the first terminal outlet hole 16 and through hole 18, so that the power line and signal line extend through the second terminal outlet hole 43, realizing the function of the connector exiting from the top.

[0039] In some embodiments, see Figure 2 , Figure 4 , Figure 5The top rear side of the base 1 is provided with multiple snap-fit ​​positions 61, and the bottom rear side of the base 1 is provided with snap-fit ​​strips 62 extending in the left and right direction. The top and bottom of the mounting cover 5 are provided with multiple connecting structures 63, which are snap-fitted into the snap-fit ​​positions 61 and snap-fit ​​strips 62 respectively, so as to snap the mounting cover 5 into the rear side of the base 1 and ensure that the mounting cover 5 is stably installed in the base 1.

[0040] It is understood that the connecting structure 63 corresponding to the snap-fit ​​position 61 can be configured according to the structure of the snap-fit ​​position 61. For example, when the snap-fit ​​position 61 is a protrusion, the connecting structure 63 can be configured as a hole structure that mates with the protrusion; when the snap-fit ​​position 61 is a groove, the connecting structure 63 can be configured as a protrusion or hook-shaped structure that mates with the groove. No restrictions are imposed here. Furthermore, see also... Figure 5 The connection structure 63 corresponding to the card slot 61 can be configured as a hook structure, or as an L-shaped groove structure, etc., without limitation.

[0041] In some embodiments, both the latch 2 and the base 1 are made of plastic material, which facilitates the snap-fit ​​between the connector and the printed circuit board 3, and also serves as insulation.

All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
