Description

Technical Field

[0001] This utility model relates to the field of connectors, and more particularly to a connector assembly with a sliding frame. Background Technology

[0002] Connectors are a common component in electrical engineering. Their function is to connect circuits on different devices or different modules in a circuit, so that current or signals can flow or be transmitted, and the circuit can perform its intended function.

[0003] In the application of connectors in the cabinet, fixed connection devices and sliding connection devices are generally equipped. The sliding connection device connects or separates from the fixed connection device through the telescopic movement of the slide rail. During the sliding connection process, the sliding connection device needs to be configured with isolation position, test position and working position. The isolation position is used to separate the fixed connection device and the sliding connection device, the test position is used for the pre-positioning connection of the fixed connection device and the sliding connection device, and the working position is used for the electrical connection between the terminals. Therefore, corresponding structures need to be designed to realize the corresponding connection functions. Utility Model Content

[0004] The purpose of this invention is to provide a connector assembly with a sliding frame.

[0005] To achieve the objective of this utility model, a connector assembly with a sliding frame is provided, including a fixed connection device and a sliding connection device. The fixed connection device includes a fixed frame and a fixed connector. The fixed connector includes a fixed housing and a fixed terminal. The fixed terminal is installed inside the fixed housing. The fixed housing is installed inside a fixed mounting hole in the fixed frame. The outer wall of the fixed housing is provided with a limit block and a limit step. The limit step is located on the inner side of the limit block based on the fixed frame. The sliding connection device includes a sliding frame and a sliding connector. The sliding connector includes a sliding housing and a sliding terminal. The sliding terminal is installed inside the sliding housing. The sliding frame includes a sliding baffle and a sliding bracket. The sliding bracket is fixedly installed on the sliding baffle. The sliding baffle and the sliding bracket are provided with a connection mounting hole through them along the insertion direction. The sliding bracket is provided with at least two guide arms along the insertion direction. The guide arms are perpendicular to the sliding baffle, and the free ends of the guide arms are... The sliding connector is arranged sequentially from the outside inwards, including a connecting guide surface, a separating stop surface, a connecting stop surface, and a separating guide surface. The connecting guide surface and the separating guide surface are inclined in opposite directions, and the separating stop surface and the connecting stop surface are opposite to each other. A receiving groove is formed between the two guide arms. The sliding housing is movably disposed in the receiving groove along the insertion direction. The outer wall of the sliding housing is provided with a positioning protrusion. When the sliding connector is connected to the fixed connector along the insertion direction, the connecting guide surface slides and engages with the limiting block and moves into the limiting step. The connecting stop surface is adjacent to the positioning protrusion and drives the sliding housing to move forward along the insertion direction, and the fixed connector is connected to the sliding connector. When the sliding connector is separated from the fixed connector along the insertion direction, the separating guide surface slides and engages with the limiting block and disengages from the limiting step. The separating stop surface is adjacent to the positioning protrusion and drives the sliding housing to move backward along the insertion direction, and the fixed connector is separated from the sliding connector.

[0006] A further proposed solution is that the sliding bracket has two support arms along the insertion direction, with the two support arms located at both ends of the length direction. The support arms are provided with sliding grooves along the insertion direction, and the sidewalls of the sliding housing are provided with sliders at both ends of the length direction, with the sliders slidingly engaging with the sliding grooves.

[0007] A further solution is to provide a limiting groove along the insertion direction of the support arm, with a stop wall at the end of the limiting groove facing the fixed connection device, and an opening at the end of the limiting groove away from the fixed connection device. A limiting block is provided on the slider, and the limiting block is slidably fitted with clearance within the limiting groove.

[0008] A further proposed solution is to have a positioning post on the slider along the insertion direction, a guide hole on the positioning post along the insertion direction, and a guide post on the fixing frame along the insertion direction, with the guide post and guide hole having a clearance fit.

[0009] A further proposed solution is to have a sliding bracket with four guide arms, arranged in pairs on both sides of the width direction, with the four guide arms and two support arms forming a receiving groove.

[0010] A further proposed solution is that when the sliding connecting device is connected to the fixed connecting device in the insertion direction, the end of the sliding housing in the insertion direction is located at the connection mounting hole.

[0011] A further improvement is that the fixed frame has a through groove along the insertion direction at the edge of the fixed mounting hole, the limiting block and the limiting step are located at the through groove, and the free end of the guide arm can pass through the through groove.

[0012] The beneficial effects of this utility model are as follows: When the sliding connection device is connected to the fixed connection device along the insertion direction, at the test position, the connecting guide surface passes through the through groove and slides with the limiting block, then moves into the limiting step. The slider slides with the groove, and the limiting block slides with the limiting groove. The guide post and guide hole also cooperate with each other, thus ensuring the accurate positioning of the sliding connection device. The connecting stop surface and the positioning protrusion are adjacent to each other and drive the sliding shell to move forward along the insertion direction, thereby completing the connection between the fixed connector and the sliding connector at the working position. When separating, at the test position, the separating guide surface slides with the limiting block and disengages from the limiting step. The separating stop surface and the positioning protrusion are adjacent to each other and drive the sliding shell to move backward along the insertion direction, finally achieving the separation of the fixed connector and the sliding connector at the isolation position, thereby improving the connection stability of the connector and the accuracy of the insertion process.

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0026] Reference Figures 1 to 6 The connector assembly includes a fixed connecting device 1 and a sliding connecting device 2. The fixed connecting device 1 includes a fixed frame 11 and a fixed connector 12. The fixed connector 12 includes a fixed housing 120 and a fixed terminal 13. The fixed terminal 13 is installed inside the fixed housing 120. The fixed housing 120 is installed inside the fixed mounting hole 112 of the fixed frame 11. The outer wall of the fixed housing 120 is provided with four limiting blocks 121 and four limiting steps 122. The limiting steps 122 are located on the inner side of the limiting blocks 121 based on the fixed frame 11. The fixed frame 11 is used for fixed arrangement. The fixed frame 11 has four through slots 111 extending along the insertion direction Z at the edge of the fixed mounting hole 112. One limiting block 121 and one limiting step 122 are located at one through slot 111. The fixed frame 11 is provided with two guide posts 123 along the insertion direction Z. The outer ends of the guide posts 123 face the sliding connecting device 2. The two guide posts 123 are located on both sides of the length direction, while the two limiting blocks 121 are located on both sides of the width direction as a group.

[0027] The sliding connection device 2 includes a sliding frame 21 and a sliding connector 22. The sliding connector 22 includes a sliding housing 23 and a sliding terminal 24. The sliding terminal 24 is installed inside the sliding housing 23. The sliding frame 21 includes a sliding baffle 211 and a sliding bracket 212. The sliding bracket 212 is fixedly installed on the sliding baffle 211. The sliding baffle 211 and the sliding bracket 212 are provided with a connection mounting hole 210 through the insertion direction Z.

[0028] The sliding bracket 212 is provided with four guide arms 213 along the insertion direction Z. The guide arms 213 are perpendicular to the sliding baffle 211. The free ends of the guide arms 213 are arranged sequentially from the outside to the inside as a connecting guide surface 214, a separating stop surface 215, a connecting stop surface 216, and a separating guide surface 217. The connecting guide surface 214 and the separating guide surface 217 are arranged at an angle and are inclined in opposite directions. The separating stop surface 215 and the connecting stop surface 216 face each other in opposite directions, and a groove is formed between the separating stop surface 215 and the connecting stop surface 216. Two guide arms 213 are arranged as a group on both sides of the width direction. The sliding bracket 212 is provided with two support arms 218 along the insertion direction Z. The two support arms 218 are located at both ends of the length direction. The support arms 218 are provided with slide grooves 220 along the insertion direction Z. The side wall of the sliding housing 23 is provided with sliders 237 at both ends of the length direction. The sliders 237 slide with the slide grooves 220. The sliders 237 are also provided with ribs 232 on both sides of the width direction. Correspondingly, the slide grooves 220 are also provided with grooves on both sides of the width direction. The ribs 232 are in clearance fit with the grooves.

[0029] The support arm 218 is provided with a limiting groove 219 along the insertion direction Z. The limiting groove 219 has a stop wall at one end facing the fixed connection device 1, and an opening at the end away from the fixed connection device 1. A limiting block 121 is provided on the slider 237. The limiting block 121 is slidably fitted within the limiting groove 219 with a clearance fit. The limiting block 121 can abut against the stop wall of the limiting groove 219, and can also pass through the opening and disengage from the limiting groove 219. The slider 237 is provided with a positioning post 234 along the insertion direction Z. The positioning post 234 has a guide hole 235 along the insertion direction Z, and the guide post 234 is used to have a clearance fit with the guide hole 235.

[0030] Four guide arms 213 and two support arms 218 form a receiving groove. The sliding housing 23 is movable in the receiving groove along the insertion direction Z. The outer wall of the sliding housing 23 is provided with positioning protrusions 231 on both sides in the width direction. The positioning protrusions 231 extend in the length direction. The positioning protrusions 231 can be pre-assembled in the groove between the separating stop surface 215 and the connecting stop surface 216.

[0031] Reference Figure 6When the connector assembly is connected in the working position, that is, when the sliding connection device 2 is connected to the fixed connection device 1 along the insertion direction Z, the free end of the guide arm 213 can pass through the through groove 111. After the connecting guide surface 214 slides and engages with the limiting block 121, it moves into the limiting step 122. The fixed connector 12 is connected to the sliding connector 22, and the fixed terminal 13 is electrically connected to the sliding terminal 24. When the sliding frame 21 is located at the foremost side of the insertion direction Z, the sliding housing 23 is located at the end of the insertion direction Z at the connection mounting hole 210 and is clearance-fitted with the connection mounting hole 210.

[0032] Reference Figure 7 When the connector assembly is disassembled, that is, when the sliding connecting device 2 separates from the fixed connecting device 1 along the insertion direction Z, the sliding connector 22 does not move, while the sliding frame 21 moves backward along the insertion direction Z. After the separation guide surface 217 slides into contact with the limiting block 121, it disengages from the limiting step 122. At the same time, the separation stop surface 215 abuts against the positioning protrusion 231. Subsequently, the separation stop surface 215 drives the sliding housing 23 to move backward along the insertion direction Z, and so on. Figure 8 and 9 As shown, the fixed connector 12 is separated from the sliding connector 22, and the guide post 123 is separated from the guide hole 235.

[0033] Reference Figure 10 When the connector assembly is connected, the sliding frame 21 moves forward along the insertion direction Z, the connecting stop surface 216 abuts against the positioning protrusion 231 and drives the sliding housing 23 to move forward along the insertion direction Z, as shown in the reference. Figure 11 As the sliding connecting device 2 moves, the guide post 123 connects with the guide hole 235, and the connecting guide surface 214 abuts against the limiting block 121. At this time, the fixed terminal 13 and the sliding terminal 24 are electrically connected and in the working position. Further movement, such as... Figure 12 As shown, the connecting guide surface 214 slides into the limiting block 121, causing the guide arm 213 to deform outwards, and the connecting guide surface 214 separates from the positioning protrusion 231. Finally, the free end of the guide arm 213 can pass through the through groove 111 and move into the limiting step 122, and then return to the position as shown. Figure 6 Status: Connector connection complete.

[0034] As can be seen above, when the sliding connector connects to the fixed connector along the insertion direction, at the test position, the connecting guide surface slides through the through groove and engages with the limiting block, then moves into the limiting step. The sliding block and the sliding groove engage, as do the limiting block and the limiting groove. The guide post and the guide hole also engage, ensuring the precise positioning of the sliding connector. The connecting stop surface and the positioning protrusion are adjacent to each other and drive the sliding housing to move forward along the insertion direction, thus completing the connection between the fixed connector and the sliding connector at the working position. During separation, at the test position, the separating guide surface and the limiting block engage, then the sliding surface disengages from the limiting step. The separating stop surface and the positioning protrusion are adjacent to each other and drive the sliding housing to move backward along the insertion direction, finally achieving the separation of the fixed connector and the sliding connector at the isolation position. This improves the connection stability and the accuracy of the insertion process.
