Elastic connector

Abstract

The elastic connector comprises a first connecting module and a second connecting module, a first mounting block and a second mounting block are respectively inserted from the front end and the rear end of a bus copper bar in the mounting process, and the front end of the first mounting block and the front end of the second mounting block are overlapped in a half-insertion and non-tightening state. The distance between the upper elastic piece and the lower elastic piece is larger than the gap between the copper bars to achieve convenient insertion, and when the front ends of the first installation block and the second installation block are overlapped, the overlapping thickness is increased, so that the upper elastic piece and the lower elastic piece are compressed to form an independent tightening communication effect on each copper bar, and enough clamping pressure is guaranteed. The connector upper pressing plate and the connector lower pressing plate are fixed on the upper side and the lower side of the first fixing plate respectively, and a limiting column penetrating between the elastic piece set and the first mounting block is connected between the connector upper pressing plate and the connector lower pressing plate, so that looseness caused by expansion of the whole structure in the insertion process can be avoided.

Description

Technical Field

[0001] The utility model relates to the field of electrical equipment, and specifically relates to an elastic connector. Background Art

[0002] The end distribution busbar is a new power supply and distribution method formed by using copper or aluminum as conductors, supported by insulating parts, and then installed in a metal trough. It is widely used in the end distribution of data centers nowadays. The outgoing equipment for end distribution is a plug-in box. For the convenience of equipment connection, the busbar copper bars are usually designed in a fixed-spacing mode. Each busbar segment needs to be connected using a busbar connector. Traditional connectors are usually of a sandwich structure, that is, the connecting copper bars and insulating plates are arranged at intervals, and the busbars are tightly connected by means of a through-long bolt locking method.

[0003] For example, the patent with the publication number CN115693558A discloses a data center busbar connector, which relates to the field of data center power distribution equipment, and includes an upper housing and a lower housing. The lower housing is regularly provided with several groups of socket strips; the lower housing is provided with a lower insulating layer; the socket strip includes an inverted T-shaped conductor embedded in the lower insulating layer and a socket assembly assembled on the inverted T-shaped conductor; the socket assembly is composed of a socket piece and a spring piece; the socket piece is used for socketing the busbar conductor and applying a clamping pressure to the conductor; the spring piece is used to provide an elastic pressure to the socket piece to enhance the clamping pressure of the socket piece and increase the conductor thickness of the socket assembly.

[0004] Another example is the patent with the publication number CN114709776A, which discloses a plug-in integral connector for busbar troughs, including a connector base. The connector base is provided with several rectangular grooves penetrating both ends of the connector base. The bottom of the rectangular groove is also provided with a T-shaped groove penetrating both ends of the connector base. A T-shaped block matching the T-shaped groove is arranged in the T-shaped groove, and a busbar connecting piece is arranged on the T-shaped block. The busbar connecting piece includes a pair of spring pieces. The spring pieces are respectively arranged on the left and right sides of the T-shaped block and are symmetrical about the central plane of the T-shaped block. The tail of the spring piece is connected to the T-shaped block. The head of the spring piece is arc-shaped and bends inward. The two spring pieces form an "x" shape. Reinforcing pieces are arranged on the outer sides of the two spring pieces. The bottom of the reinforcing piece is connected to the bottom of the spring piece. The reinforcing piece covers the outer side of the spring piece and the head of the reinforcing piece abuts against the bending part of the spring piece.

[0005] To sum up, there are still many drawbacks in the current connectors: if the spacing of the sandwich is equal to or slightly larger than the copper bar spacing, it will cause difficulties in inserting the connector. If it is larger than the copper bar spacing, although the problem of difficult insertion is solved, the equally spaced copper bars will be deformed during the process of tightening with bolts, that is, it affects the tightening effect and may also affect the plugging of the equipment.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0033] An elastic connector includes a first connection module 1 and a second connection module 2. The first connection module 1 is inserted into the second connection module 2. The first connection module 1 includes a connector upper pressing plate 11, a shrapnel group 12, a first fixing plate 13, a connector lower pressing plate 14, and a first mounting block 15.

Several groups of the first mounting blocks 15 are arranged at intervals and are respectively connected to the first fixing plate 13. Several groups of the shrapnel groups 12 are provided and are respectively located at positions between two adjacent first mounting blocks 15. The second connection module 2 includes a second fixing plate 21 and a second mounting block 22. Several second mounting blocks 22 are provided and are connected to the second fixing plate 21 at positions corresponding to the first mounting blocks 15.

The upper spring sheet 121 and the lower spring sheet 122 are arranged opposite to each other, and the elastic deformation clearance of the upper spring sheet 121 and the distance for the lower spring sheet 122 to move up and down are reserved between them. The upper spring sheet 121 and the lower spring sheet 122 are provided with three layers from the outside to the inside, and the edges of the left and right ends are bent toward the center of the two. The front and rear ends of the first mounting block 15 and the second mounting block 22 correspond to each other in a stepped shape from front to back. After the front and rear ends of the first mounting block 15 and the second mounting block 22 are gradually fitted and pushed forward, the distance between the upper spring sheet 121 and the lower spring sheet 122 can be compressed. A limiting column 3 is provided between the upper pressure plate 11 of the connector and the lower pressure plate 14 of the connector, which is penetrated between the spring sheet group 12 and the first mounting block 15, and the upper pressure plate 11 of the connector and the lower pressure plate 14 of the connector are connected to the limiting column 3 to resist the first mounting block 15 on the upper and lower sides.

During the installation process, the first mounting block 15 and the second mounting block 22 are respectively inserted from the front and rear ends of the busbar copper bar. In the semi-inserted and untightened state, the front ends of the first mounting block 15 and the second mounting block 22 overlap, and the distance between the upper spring sheet 121 and the lower spring sheet 122 is greater than the gap between the copper bars to facilitate insertion.
