Description

Technical Field

[0001] This utility model relates to the field of connectors, and more particularly to a mating connector for electrical control cabinets. Background Technology

[0002] In electrical control cabinets in the fields of power control or communication, drawers are usually provided. In order to achieve power conduction or communication, one or more connectors are fixed on the outer surface of the front panel of the drawer for mating with the corresponding plug terminals in the cabinet, thereby realizing the quick connection or disconnection of the circuit board inside the drawer and the circuit of the cabinet.

[0003] However, in some specific application scenarios, it is necessary to install mating connectors on the side wall of the drawer. Since the space between the side wall of the drawer and the side wall of the cabinet is narrow, the connectors must be narrow enough to facilitate installation in a confined space, and a relatively reasonable degree of mating redundancy must be provided for the two connectors. Utility Model Content

[0004] The purpose of this invention is to provide a docking connector for electrical control cabinets.

[0005] To achieve the purpose of this utility model, this utility model provides a docking connector for an electrical control cabinet, including a fixed panel, a fixed connector, a drawer panel, and a sliding connector. The fixed panel has a fixed mounting groove extending through it in the lateral direction. The fixed connector includes a fixed housing, a fixed terminal, and two fixed springs. The fixed housing has a first terminal hole in the insertion direction, and the fixed terminal is disposed in the first terminal hole in the insertion direction. The fixed housing is installed at the fixed mounting groove. The first terminal hole is located on the inner side of the fixed panel in the lateral direction. The outer wall of the fixed housing has a locking block at each end in the insertion direction. The two fixed springs are installed on the outer wall of the fixed housing and are located at each end in the insertion direction. The locking block and the fixed spring on the same side are located on the inner and outer sides of the fixed panel in the lateral direction, respectively. The fixed panel is adjacent to the locking block and the fixed spring. The drawer panel is located on the inner side of the fixed panel in the lateral direction and can move in the insertion direction. The drawer panel has a sliding mounting groove extending through it in the lateral direction. The sliding connector is installed at the sliding mounting groove and moves in the insertion direction with the drawer panel. The sliding connector has a sliding terminal and is connected to the fixed connector. The sliding terminal is connected to the fixed terminal.

[0006] A further solution is to provide a fixed end and an elastic protrusion for the fixing spring, with the elastic protrusion protruding towards the locking block, the fixed end being fixedly connected to the outer wall of the fixing housing, and the fixing panel being adjacent to the locking block and the elastic protrusion.

[0007] A further proposed solution is to have the fixed end arranged in an L-shape, with an L-shaped slot on the outer wall of the fixed housing, and the fixed end installed in the L-shaped slot.

[0008] A further improvement is that the fixed spring has a free end, the elastic protrusion is located between the fixed end and the free end, and the outer wall of the fixed housing has a slot through which the free end passes.

[0009] A further proposed solution is to have a mating groove on the outer wall of the fixed housing between the locking block and the fixing spring, with the fixing panel located within the mating groove.

[0010] A further proposed solution is to provide connecting springs on both sides of the outer wall of the fixed housing in the insertion direction, and to provide connecting slots on both sides of the sliding connector in the insertion direction, with the connecting springs engaging with the connecting slots.

[0011] A further improvement is that the card block has a mating bevel on the side facing the sliding connector, which mates with the edge bevel of the fixed mounting groove.

[0012] The beneficial effects of this utility model are as follows: By using a fixed connector and a sliding connector located in the lateral direction, the two connectors can be connected along the insertion direction at the side wall of the electrical control cabinet. Furthermore, the fixed panel is clamped on both sides by a locking block and a fixing spring. Since the fixing spring has a certain amount of elastic movement, the fixed connector also has a certain amount of elastic movement space in the lateral direction. Because the drawer panel is generally moved via a slide rail assembly, it has a certain offset in the lateral direction during movement. Therefore, when the two connectors are connected, the elastically movable fixed connector can better connect with the sliding connector, utilizing the mating redundancy to improve connection stability. Moreover, by fixing the fixed end, the free end passes through the limiting of the slot, allowing the elastic protrusion to tightly contact the fixed panel. The assembly of the fixing spring is improved by the L-shaped locking slot. Furthermore, the assembly of the mating groove with the fixed panel, and the mating bevel with the edge bevel of the fixed mounting groove, further improves the assembly convenience and stability of the fixed connector.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments. Detailed Implementation

[0021] Reference Figures 1 to 7 The docking connector includes a fixed panel 1, a fixed connector 2, a drawer panel 31, and a sliding connector 32. The fixed panel 1 is the side wall of the electrical control cabinet, and a fixed mounting groove 11 is provided through the fixed panel 1 in the lateral direction X.

[0022] The fixed connector 2 includes a fixed housing 21, multiple fixed terminals 212, and two fixed springs 22. The fixed housing 21 has multiple first terminal holes 211 along the insertion direction Z. Each fixed terminal 212 is disposed in a first terminal hole 211 along the insertion direction Z. The fixed housing 21 is installed through the fixed mounting groove 11. The first terminal holes 211 are located on the inner side of the fixed panel 1 in the lateral direction X. The outer wall of the fixed housing 21 has locking blocks 213 at both ends of the insertion direction Z. The two fixed springs 22 are installed on the outer wall of the fixed housing 21 and are located at both ends of the insertion direction Z. The cross-section of one locking block 213 is arranged in a trapezoidal shape. The other locking block 213 has a mating slope 2131 on the side facing the sliding connector 32. When the fixed housing 21 is installed on the fixed panel 1, the locking block 213 on one side is first engaged with the edge of the fixed mounting groove 11, and then the mating slope 2131 is engaged with the edge slope of the fixed mounting groove 11.

[0023] The fixing spring piece 22 is provided with a fixing end 221, an elastic protrusion 222, and a free end 223. The elastic protrusion 222 protrudes towards the locking block 213. The fixing end 221 is fixedly connected to the outer wall of the fixing housing 21. The fixing end 221 is arranged in an L-shaped plate shape. The outer walls of the fixing housing 21 at both ends of the insertion direction Z are respectively provided with protrusions. The protrusions are provided with L-shaped slots. The fixing end 221 of each fixing spring piece 22 is installed in the L-shaped slot. The outer walls of the fixing housing 21 at both ends of the insertion direction Z are also provided with slots 217. The slots 217 are formed by a straight plate and a triangular prism on the outer wall. The tip of the triangular prism faces the straight plate. The elastic protrusion 222 is located between the fixing end 221 and the free end 223. The free end 223 passes through the slot 217.

[0024] The outer wall of the fixed housing 21 has a mating groove 214 between the locking block 213 and the fixing spring piece 22. The edge of the fixing mounting groove 11 of the fixed panel 1 is located within the mating groove 214. The locking block 213 and the fixing spring piece 22 on the same side are located on the inner and outer sides of the fixed panel 1 according to the lateral direction X, respectively. The fixed panel 1 is adjacent to the locking block 213 and the elastic protrusion 222. The lateral direction X is perpendicular to the insertion direction Z. When the fixed connector 2 is connected to the sliding connector 32, the fixed connector 2 can move along the lateral direction X, thereby providing redundancy for the connection and mating process.

[0025] The drawer panel 31 is located inside the fixed panel 1 in the lateral direction X and can move in the insertion direction Z. The drawer panel 31 is the side wall part of the drawer of the electrical control cabinet. The drawer panel 31 is provided with a sliding mounting groove 311 through in the lateral direction X. The sliding connector 32 is installed in the sliding mounting groove 311. The sliding connector 32 moves in the insertion direction Z with the drawer panel 31. The sliding connector 32 is provided with a plurality of second terminal holes. The second terminal holes are provided with sliding terminals 312. As the sliding connector 32 moves in the insertion direction Z, the sliding connector 32 is connected to the fixed connector 2, and the sliding terminal 312 is connected to the fixed terminal 212.

[0026] The outer wall of the fixed housing 21 is provided with connecting springs 23 on both sides of the insertion direction Z, and the sliding connector 32 is provided with connecting slots 321 on both sides of the insertion direction Z. The connecting springs 23 engage with the connecting slots 321, thereby maintaining the connection relationship between the sliding connector 32 and the fixed connector 2.

[0027] As can be seen from the above, the fixed connector and the sliding connector located on the side allow the two connectors to be connected along the insertion direction at the side wall of the electrical control cabinet. Furthermore, the fixed panel is clamped on both sides by the locking block and the fixing spring. Since the fixing spring has a certain amount of elastic movement, the fixed connector also has a certain amount of elastic movement space in the side direction. Since the movement of the drawer panel is generally achieved by slide rail assembly, it has a certain amount of offset in the side direction when it moves. Therefore, when the two connectors are connected, the elastically movable fixed connector can better connect with the sliding connector, and the connection stability is improved by utilizing the matching redundancy.
