Description

Technical Field

[0001] This utility model relates to the field of drawer cabinet insert technology, and in particular to a reinforced drawer one-time static insert. Background Technology

[0002] Currently, the primary connectors in domestically produced drawer cabinets consist of moving and stationary connectors. Power is supplied by inserting conductive plates on the moving connectors into the conductive busbars in the stationary connectors. However, due to factors such as manufacturing processes and material costs, the conductive busbars in existing domestic drawer cabinets are generally solid copper busbars. Since solid copper busbars are usually directly mounted on the main body of the connector, when the cable is connected, the tensile stress generated by the cable's own weight or circumferential pulling under external force can easily cause the solid copper busbars to deform, resulting in poor contact. Utility Model Content

[0003] The purpose of this utility model is to provide a reinforced drawer one-time static insert to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides a reinforced drawer single-piece static insert, including an insert body installed on the drawer and a copper busbar installed on the insert body, and a sheet metal bracket installed on the drawer. The insert body is located inside the sheet metal bracket, the copper busbar passes through the sheet metal bracket, and the sheet metal bracket is provided with a plurality of limiting members. Each limiting member is provided with a sleeve that cooperates with the copper busbar. The limiting members are made of insulating material.

[0009] Furthermore, the sheet metal bracket is provided with an inclined plate, and the sheet metal bracket is provided with a hole for the copper busbar to pass through, and there is a gap between the inner wall of the hole and the copper busbar.

[0010] Furthermore, a bending plate is provided between two adjacent limiting members, a protective cover is embedded in the bending plate, the top plate of the protective cover overlaps the top of the bending plate, and the copper busbar is located inside the protective cover.

[0011] Furthermore, the protective cover is made of a transparent material.

[0012] Furthermore, the top of the protective cover is provided with several heat dissipation grooves, which are located directly above the copper busbar.

[0013] Furthermore, the protective cover has a plug hole on the side opposite to the sheet metal bracket to facilitate the connection of cables and the copper busbar.

Detailed Implementation

[0022] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0023] In one embodiment, such as Figure 1-2 As shown, a reinforced drawer primary static connector includes a connector body 3 mounted on the drawer and a copper busbar 6 mounted on the connector body 3, as well as a sheet metal bracket 4 mounted on the drawer. The connector body 3 is located inside the sheet metal bracket 4, and the copper busbar 6 passes through the sheet metal bracket 4. The sheet metal bracket 4 is provided with three limiting members 5, and each limiting member 5 is provided with a sleeve 16 that cooperates with the copper busbar 6. The limiting members 5 are made of insulating material to prevent the sleeve 16 from affecting the circuit. The sleeve 16 and the copper busbar 6 can cooperate in a clearance fit, which can greatly improve the circumferential tensile strength of the copper busbar 6. When the copper busbar 6 is subjected to circumferential tensile strength, the limiting effect of the sleeve 16 ensures the connection between the copper busbar 6 and the connector body 3, thereby effectively preventing the copper busbar 6 from deforming. Therefore, when the cable is connected, the sleeve 16 can prevent the copper busbar 6 from deforming under the weight of the cable or under the action of external force, thus preventing poor contact.

[0024] In this embodiment, a rib plate 2 is fixedly connected to the sheet metal bracket 4, and the insert body 3 is located below the rib plate 2. When the sheet metal bracket 4 moves down, the rib plate 2 overlaps with the insert body 3, which helps to prevent the sheet metal bracket 4 from deforming, thereby preventing the sleeve 16 from moving, and ultimately preventing the copper busbar 6 from deforming. The limiting member 5 also includes a base plate 14 fixedly connected to the sheet metal bracket 4, and a sleeve 16 is provided on the base plate 14. The connection between the base plate 14 and the sheet metal bracket 4, and between the sheet metal bracket 4 and the drawer, can all be achieved by screw and nut connection. Several reinforcing ribs 15 are provided between the outer walls of the base plate 14 and the sleeve 16 to prevent the sleeve 16 from bending, thereby improving the support strength of the sleeve 16. The copper busbar 6 and the sleeve 16 are provided with Aligned fixing holes are provided, through which the plug pin 17 passes to fix the copper busbar 6 and the sleeve 16. The plug pin 17 is interference-fitted with the fixing hole, thus ensuring the connection strength between the sleeve 16 and the copper busbar 6. At the same time, the sleeve 16 can withstand the axial force on the copper busbar 6, which helps to prevent the copper busbar 6 from coming off the plug body 3. The plug pin 17 is made of insulating material. In addition, in order to improve the support strength and facilitate processing, the sheet metal bracket 4 is made of stainless steel. Therefore, the sheet metal bracket 4 is provided with an inclined plate 1 to improve the support strength of the sheet metal bracket 4. The sheet metal bracket 4 is provided with a hole for the copper busbar 6 to pass through. There is a gap between the inner wall of the hole and the copper busbar 6 to prevent the stainless steel sheet metal bracket 4 from directly contacting the copper busbar 6 and preventing leakage. In the case of electrical issues, the surface of the sheet metal bracket 4 can be plastic-sealed to facilitate insulation. A bending plate 12 is provided between two adjacent limiting members 5, with a protective cover 9 embedded in the bending plate 12. The top plate of the protective cover 9 overlaps the top of the bending plate 12, and the copper busbar 6 is located inside the protective cover 9, which helps reduce direct collisions between the copper busbar 6 and the copper busbar 6. The protective cover 9 is made of transparent material for easy observation and cable connection. Several heat dissipation slots 10 are provided on the top of the protective cover 9, located directly above the copper busbar 6, which facilitates heat dissipation. A plug-in hole 8 is provided on the side of the protective cover 9 away from the sheet metal bracket 4 to facilitate cable and copper busbar 6 connection. Several identification characters 7 are arrayed on the top of the protective cover 9. Above the copper busbar 6, the identification character 7 can be either a number or an English letter, making it easy to identify different cables. The interior of the cover 9 has several partitions 11, which are detachably connected to the bending plate 12. The bending plate 12 has a dovetail groove 13, and the partitions 11 have positioning ribs that fit with the dovetail groove 13. Therefore, when the cover 9 needs to be installed, simply insert the positioning ribs into the dovetail groove 13 from top to bottom. When the top plate of the cover 9 overlaps the top of the bending plate 12, the installation is complete. When it needs to be removed, simply lift the cover 9 from bottom to top. The operation is simple. The dovetail groove 13 helps to prevent the cover 9 from moving away from the sheet metal bracket 4, thus ensuring the stability of the cover 9 connection.The bending plate 12 is an L-shaped plate, and the connection between the bending plate 12 and the base plate 14 can be achieved by using screws and nuts.

[0025] Working principle: When the copper busbar 6 is subjected to circumferential tension, the sleeve 16 limits the connection between the copper busbar 6 and the plug body 3, thereby effectively preventing the copper busbar 6 from deforming. Therefore, when the cable is connected, the sleeve 16 can prevent the copper busbar 6 from deforming under the weight of the cable or under the action of external force, thus preventing poor contact.
