DETAILED DESCRIPTION

[0029] Please refer to Figures 1-5 In the embodiment of the application, a connector mounting assembly for a circuit board includes a base plate connector 1 and an object connector 2, the base plate connector 1 is provided with a clamping piece 4 connected elastically, two clamping grooves 11 are symmetrically embedded on both sides of the base plate connector 1, and two groups of clamping grooves 11 are elastically embedded with clamping strips 1101 on opposite sides, the clamping piece 4 is in transmission connection with the clamping strips 1101 through a traction piece 3, when the clamping piece 4 moves towards the base plate connector 1, the clamping piece 4 pulls the clamping strips 1101 to move towards the clamping grooves 11 through the traction piece 3, the clamping strips 1101 are in active adaptation with the side slots 22 symmetrically arranged on the side of the object connector 2, and the clamping piece 4 is in active adaptation with the end slots 23 embedded at the end of the object connector 2.

[0030] In the embodiment, preferably, the substrate connector 1 and the object connector 2 can be assembled by clamping. The upper end of the object connector 2 is symmetrically and integrally formed with wing edges 21 on both sides. The wing edges 21 are correspondingly arranged and movably fitted with the clamping grooves 11. The edge grooves 22 are embedded at the edges of the wing edges 21. The positions of the edge grooves 22 correspond to the clamping strips 1101. When the substrate connector 1 and the object connector 2 are not assembled, the clamping strips 1101 are in a state of extending out of the side edges of the clamping grooves 11. In use, first, the side of the object connector 2, on which the end groove 23 is arranged, is tilted downward and correspondingly pressed against the clamping piece 4, so that the clamping piece 4 is pressed into the substrate connector 1. In this way, the clamping piece 4 can pull the clamping strips 1101 into the clamping grooves 11 through the traction piece 3. At this time, the object connector 2 is entirely embedded into the opening of the substrate connector 1. At this time, the clamping piece 4 is still in the pressed state, so the clamping strips 1101 are still located in the side edges of the clamping grooves 11. The object connector 2 is radially slid relative to the substrate connector 1, so that the clamping piece 4 slides out from below the object connector 2. The clamping piece 4 can be popped out of the substrate connector 1. At this time, the clamping piece 4 no longer pulls the clamping strips 1101. In this way, the clamping strips 1101 can also be popped out of the side edges of the clamping grooves 11 and fitted in the edge grooves 22. Then, the object connector 2 is retracted. The end groove 23 at the end of the object connector 2 can be clamped and fitted with the clamping piece 4. In this way, the assembly is simple, and can be limited in multiple directions. After assembly, the substrate connector 1 and the object connector 2 are automatically and stably limited. Even in shaking, they cannot be detached, and will not affect the stability of data transmission in use.

[0031] Further, preferably, as Figures 1-2As shown in FIG. 7, the substrate connector 1 is in a concave shape structure, the object connector 2 is movably matched on the opening of the substrate connector 1, the other end of the opening of the substrate connector 1 is provided with an end cover 12, the gasket 1201 is slidably embedded on the end cover 12, the blind hole 1202 is embedded on the side of the gasket 1201, the connecting rod 1203 is slidably matched in the blind hole 1202, the end of the connecting rod 1203 away from the gasket 1201 is fixedly connected with the end cover 12, and the end of the connecting rod 1203 extending into the blind hole 1202 is elastically connected with the blind hole 1202. The elastic connection can be spring connection, and the spring acts on the gasket 1201 to make it away from the end cover 12. The edge of the gasket 1201 is chamfered, so that the end of the object connector 2 can pass through without jamming, and the gasket 1201 can be extruded. In use, when the object connector 2 is installed, one side of the object connector 2 extrudes the card piece 4 first, and after the card strip 1101 is received, the other side of the object connector 2 is pressed into the opening of the substrate connector 1. According to the different positions of the object connector 2, the end of the object connector 2 may or may not extrude the gasket 1201, but when the object connector 2 slides forward so that the object connector 2 no longer extrudes the card piece 4, the end of the object connector 2 will extrude the gasket 1201, and the card strip 1101 and the edge groove 22 can also slide radially relative to each other while being clamped. When the object connector 2 is no longer pushed, the object connector 2 can be pushed to the card piece 4 by the reaction force between the gasket 1201 and the end cover 12, and the clamping cooperation between the card piece 4 and the end groove 23 is formed. The gasket 1201 and the card piece 4 can cooperate to limit the radial shaking of the object connector 2 relative to the substrate connector 1, and the cooperation between the card strip 1101 and the edge groove 22 can limit the object connector 2 from moving away from the substrate connector 1 in the vertical direction. This multi-directional limiting cooperation can improve the connection stability.

[0032] In the above embodiment, the object connector 2 is connected to the substrate connector 1 through the card piece 4 and the card strip 1101, and the object connector 2 is connected to the substrate connector 1 through the card piece 4 and the card strip 1101. Figures 1-6As shown, the cross section of the clamping piece 4 is in the shape of “┓”, the clamping piece 4 comprises a clamping part 41 and a sliding part 42 which are integrally arranged, the clamping part 41 is correspondingly matched with the end groove 23, the sliding part 42 is slidingly matched with the opening bottom of the baseboard connector 1, the bottom of the sliding part 42 is elastically connected with the baseboard connector 1, and the side edge of the sliding part 42 is embedded with a guide groove 43, and the guide groove 43 is provided with a guide assembly which is matched with the end of the traction piece 3. The bottom of the baseboard connector 1 is provided with a slot hole, which facilitates the sliding matching of the clamping piece 4, the opening size of the slot hole is matched with the size of the clamping part 41, and the elastic connection is preferably achieved by spring connection, and the spring here tends to make the clamping piece 4 move away from the bottom of the baseboard connector 1. When the clamping piece 4 slides into the baseboard connector 1, the guide assembly in the guide groove 43 can make the traction piece 3 move on it, thereby forming traction on the clamping strip 1101, and when the clamping piece 4 is reset, the traction piece 3 can move on the guide assembly and release the traction on the clamping strip 1101.

[0033] As shown in the drawings, Figures 8-9 The guide assembly comprises a slope surface 4301 arranged in the guide groove 43, the slope surface 4301 is an arc surface structure, and the guide rails 4302 are symmetrically embedded on the inner walls of the guide grooves 43 on both sides of the slope surface 4301, the sliding block 4303 is slidingly connected between the two groups of guide rails 4302, and the female head 31 of the end of the traction piece 3 is fixedly connected and arranged to be assembled and connected with the sliding block 4303. Preferably, the center of the guide rail 4302 coincides with the center of the slope surface 4301, when the clamping piece 4 is not pressed into the baseboard connector 1, the end of the traction piece 3 is located below the slope surface 4301, when the clamping piece 4 is pressed downward, the end of the traction piece 3 is connected to the sliding block 4303 through the female head 31 and slides on the guide rail 4302, when it slides upward, the traction effect can be generated by the traction piece 3, and the same is true when the clamping piece 4 moves away from the baseboard connector 1. The matching between the female head 31 and the sliding block 4303 is screw thread matching connection, the two ends of the sliding block 4303 are slidingly matched with the guide rails 4302 and can be relatively rotated, which facilitates sliding traction.

[0034] In order to improve the effect of guiding, as shown in the drawings, Figure 6 The guide groove 43 is provided with a clamping cover 44 at the opening, the clamping cover 44 is provided with a through hole, the through hole is used to pass through the traction piece 3, and the edge of the through hole is chamfered, which facilitates the limitation of the direction of the traction piece 3 and improves the traction effect.

[0035] Specifically, as shown in the drawings, Figures 1-4As shown, the two sides of the substrate connector 1 are symmetrically embedded with wire slots 13, the traction member 3 passes through the wire slots 13, and the end away from the clamping piece 4 is connected with the clamping strip 1101 through the female head 31. Preferably, the clamping strip 1101 is connected in the side wall of the clamping groove 11 through a spring, and the end of the clamping strip 1101 embedded in the clamping groove 11 is fixedly connected with a joint 1102 that is screwed with the female head 31. The spring on the clamping strip 1101 tends to move away from the clamping groove 11, and the traction member 3 can pull the clamping strip 1101 to slide into the side wall of the clamping groove 11 through the cooperation of the female head 31 and the joint 1102. The arrangement of the wire slot 13 also facilitates the concealment of the traction member 3, which can improve the service life of the traction member 3 and reduce interference. The material of the traction member 3 can be selected from metal wires, polymer material wires, or wire materials commonly used in the prior art.

[0036] In actual use, the gasket 1201 and the clamping piece 4 can be stuck together with the object connector 2. Since the gasket 1201 is elastic, if the data line is curled and has a pushing force on the object connector 2 after the data line is connected to the object connector 2, there is a certain unstable factor in the connection between the object connector 2 and the substrate connector 1. Therefore, as shown, Figures 10-11 As shown, the edge groove 22 is embedded with a limiting groove 2201, the limiting groove 2201 is a "┓" shaped hole, one end of the limiting groove 2201 is through the edge groove 22, and the other end is through the side wall of the wing edge 21, a roller 2202 is rotatably connected in the opening through the side wall of the wing edge 21, the roller 2202 is rotatably connected with the limiting groove 2201 through a core shaft 2203, and a clamping plate 2204 is fixedly connected outside the core shaft 2203, and the clamping plate 2204 rotates between the limiting groove 2201 and the edge groove 22. Preferably, the side of the roller 2202 is flush with the opening of the limiting groove 2201, or the roller 2202 is embedded in the limiting groove 2201. Correspondingly, the clamping groove 11 needs to be provided with an opening corresponding to the limiting groove 2201 to facilitate the rotation of the roller 2202 during use. The roller 2202, the core shaft 2203, and the clamping plate 2204 rotate synchronously, and the core shaft 2203 and the limiting groove 2201 have a damping bearing rotation effect. If the structure is too small to choose a damping bearing, an interference fit can be chosen to achieve the same effect. The distance between the clamping plate 2204 and the end of the edge groove 22 away from the clamping piece 4 and the length of the clamping strip 1101 are matched, so that the substrate connector 1 and the object connector 2 can be locked, thereby maintaining the locking in all directions.

[0037] A connector for a circuit substrate comprises the connector mounting assembly described above, wherein the data lines are connected to the object connector 2, and the substrate connector 1 is arranged on the circuit substrate. The additional structure of the substrate connector 1 and the object connector 2 is designed as prior art, facilitating data transmission and connection matching, which will not be described here.

[0038] Through the above arrangement, the connection of the circuit substrate connector is still simple, but higher connection stability can be obtained, and compared with the conventional connection mode, the effectiveness of the circuit substrate in use can be better guaranteed, and the problem of interrupted connection caused by vibration, collision or other misoperation can be avoided.
