[0029] 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 the 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.

[0030] In this utility model, when directions (up, down, left, right, front, and back) are described, it is only for the convenience 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.

[0031] 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.

[0032] In this utility model, unless otherwise explicitly defined, the terms "setting," "installing," and "connecting" should be interpreted broadly. For example, they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to a fixed connection, a detachable connection, or an integrally formed connection; they can refer to a mechanical connection, an electrical connection, or a connection capable of mutual communication; they can refer to 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 in conjunction with the specific content of the technical solution.

[0033] See Figure 1 , Figure 3 and Figure 4 This utility model provides a snap-fit ​​connector, including a base 1 and a conductive terminal assembly. The base 1 has a first protrusion 11 and a second protrusion 12 extending forward, the first protrusion 11 and the second protrusion 12 being spaced apart in a left-right direction. A snap-fit ​​3 is provided at the front of the base 1, located between the first protrusion 11 and the second protrusion 12.

[0034] The front of both the first protrusion 11 and the second protrusion 12 is provided with an opening groove 13, and both the first protrusion 11 and the second protrusion 12 are provided with mounting grooves above and below the opening groove 13, such as... Figure 4 and Figure 5 As shown. The conductive terminal assembly is installed in the mounting slot, with the pins of the conductive terminal assembly extending into the opening slot 13.

[0035] The slot 13 is used to place the printed circuit board 2, and the pins of the conductive terminal assembly extending into the slot 13 are electrically connected to the printed circuit board 2. The front end of the printed circuit board 2 has a snap-fit ​​structure that engages with the latch 3 at the front of the base 1 to at least restrict the forward movement of the printed circuit board 2, thereby improving the stability of the connection between the printed circuit board 2 and the connector. Furthermore, the first protrusion 11 and the second protrusion 12 limit the movement of the printed circuit board 2 in the vertical direction, and the base 1 itself can restrict the backward movement of the printed circuit board 2, thus restricting its movement in both the vertical and horizontal directions, as well as the front and rear directions.

[0036] The snap-fit ​​connector in this technical solution can achieve a stable connection between the printed circuit board 2 and the connector by setting the snap-fit ​​3, which improves the stability of the connection between the two during use and avoids the printed circuit board 2 from falling off easily when the equipment is under vibration or shaking, or the electrical connection is unstable or the connection is faulty, thus reducing the occurrence of failures during use.

[0037] Further, see Figure 4 and Figure 5The 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. Opening grooves 13 are formed between the first upper protrusion 111 and the first lower protrusion 112, and between the second upper protrusion 121 and the second lower protrusion 122. Each of the first lower protrusion 112 and the second lower protrusion 122 has a limiting block 4 on the side away from the latch 3. Limiting grooves 21 are provided on both the left and right sides of the printed circuit board 2. The printed circuit board 2 is engaged with the limiting blocks 4 through the two limiting grooves 21 to restrict the left and right movement of the printed circuit board 2. The three-point connection between the printed circuit board 2 and the connector, formed by the latch 3 and the two limiting blocks 4, further enhances the stability of the connection between the printed circuit board 2 and the connector.

[0038] Furthermore, see Figure 1 , Figure 4 and Figure 5 The latch 3 has a main body 31 extending in the front-rear direction. A latching part 32 is provided at the top of the main body 31, and the latch 3 engages with the latching structure through the latching part 32. A pressing protrusion 311 is provided at the bottom of the main body 31. The pressing protrusion 311 is located on the left and right sides of the main body 31 and is lower than the first lower protrusion 112 and the second lower protrusion 122 on the corresponding sides. After pressing the pressing protrusion 311, the latching part 32 of the latch 3 moves downwards with the front end of the main body 31 and is lower than the height of the opening slot 13, allowing the printed circuit board 2 to be placed into the opening slot 13. Then, the pressing protrusion 311 can be released, and after the pressing protrusion 311 resets, the latching part 32 engages with the latching structure.

[0039] It is understood that the snap-fit ​​part 32 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 13 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.

[0040] See Figure 2 and Figure 5 In some embodiments, the rear side of the snap-fit ​​portion 32 has an abutment surface 321 extending in the vertical direction. The snap-fit ​​structure includes a snap-fit ​​groove. The snap-fit ​​portion 32 abuts against the inner surface of the snap-fit ​​groove through the abutment surface to snap with the printed circuit board 2, thereby preventing the printed circuit board 2 from coming out of the opening groove 13 in the front-back direction.

[0041] Further, see Figure 2The snap-fit ​​groove is projected in the vertical direction to form a first projection surface, and the snap-fit ​​part 32 is projected in the vertical direction to form a second projection surface. The first projection surface completely covers the second projection surface, 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 32 can be inserted into the snap-fit ​​groove, making the installation more convenient and quick.

[0042] In some embodiments, see Figure 4 and Figure 5 The mounting slot includes a first mounting slot 5. A first upper protrusion 111, a first lower protrusion 112, a second upper protrusion 121, and a second lower protrusion 122 each have multiple first mounting slots 5 spaced apart in the left-right direction. The first mounting slots 5 of the first upper protrusion 111 and the first lower protrusion 112 correspond one-to-one in the vertical direction, and the first mounting slots 5 of the second upper protrusion 121 and the second lower protrusion 122 also correspond one-to-one in the vertical direction. Each first mounting slot 5 penetrates the base body 1 in the front-back direction and forms a first terminal outlet hole 61 at the rear end of the base body 1. The conductive terminal assembly includes multiple signal terminals 71, which are correspondingly installed within the first mounting slots 5. After the signal terminals 71 are connected to the signal lines, the signal lines can extend out of the base body 1 through the first terminal outlet holes 61, realizing the function of the signal lines extending out of the connector in a straight line.

[0043] Further, see Figure 4 and Figure 5 The mounting slot also includes a second mounting slot. The base 1 has several through holes 62 extending in the front-to-back direction on both the left and right sides of the first mounting slot 5. The through holes 62 form second mounting slots in the first upper protrusion 111, the first lower protrusion 112, the second upper protrusion 121, and the second lower protrusion 122, respectively. The conductive terminal assembly also includes multiple power terminals 72, which are correspondingly installed in the through holes 62. The first and second pins of the power terminals 72 are correspondingly installed in the second mounting slots that communicate with the through holes 62 and extend to the opening slot 13 for electrical connection with the printed circuit board 2. After the power terminals 72 are connected to the power cord, the power cord can extend out of the base 1 through the through holes 62, realizing the function of the power cord extending out of the connector in a straight line.

[0044] Furthermore, see Figures 1 to 3 The top rear side of the base 1 is provided with a second terminal outlet hole 63 that corresponds to and passes through each of the first mounting slots 5 and through holes 62. The rear side of the base 1 is provided with a mounting cover 9 for covering the first terminal outlet hole 61 and through hole 62, so that the power line and signal line extend through the second terminal outlet hole 63, realizing the function of the connector exiting from the top.

[0045] Furthermore, the rear side of the base 1 is provided with multiple first snap-fit ​​positions 81, and the left and right sides of the base 1 are provided with second snap-fit ​​positions 82. The mounting cover 9 is provided with multiple connecting structures 91, which are snapped into the first snap-fit ​​positions 81 respectively. The left and right sides of the mounting cover 9 are respectively provided with forward-extending circumferential portions 92, which are snapped into the second snap-fit ​​positions 82 through slots 921, so as to snap the mounting cover 9 into the rear side and the left and right sides of the base 1, ensuring that the mounting cover 9 is stably installed on the base 1. It can be understood that the connecting structures 91 can be set according to the structure of the first snap-fit ​​positions 81. For example, when the first snap-fit ​​position 81 is a protrusion, the connecting structure 91 can be set as a hole structure that mates with the protrusion; when the first snap-fit ​​position 81 is a groove, the connecting structure 91 can be set as a protrusion structure that mates with the groove. There is no limitation here.

[0046] In some embodiments, both the latch 3 and the base 1 are made of plastic material, which facilitates the snap-fit ​​between the connector and the printed circuit board 2, and also serves as insulation.
