TECHNICAL FIELD

[0001] The present application relates to the field of disconnectors, in particular to an outgoing line structure of a disconnector. BACKGROUND

[0002] Disconnectors are widely used in various power systems and equipment, especially when electrical isolation, maintenance and repair are required, which can provide necessary safety protection.

[0003] The disconnector is mainly composed of a moving contact, a static contact, an insulating seat, an operating mechanism and the like. When connecting the outgoing line cable, the outgoing line cable is usually fixed on the static contact by screws to realize effective connection of the outgoing line cable and the disconnector.

[0004] In the prior art, the outgoing line structure of the disconnector is usually to connect an outgoing line cable to a static contact alone, which consumes more time when people operate and increases the cost of outgoing line cables, thereby reducing the applicability of the outgoing line structure. CONTENT OF THE UTILITY MODEL

[0005] In order to reduce the time consumed when operating and the cost of outgoing line cables, the present application provides an outgoing line structure of a disconnector.

[0006] The outgoing line structure of the disconnector provided by the present application adopts the following technical scheme:

[0007] The outgoing line structure of the disconnector comprises a switch main body, a static contact connected with the switch main body, and a connecting piece connected with the static contact, the static contact comprises a first contact and a second contact, the first contact is installed at the upper end of the switch main body, the second contact is arranged at the lower side of the first contact and connected with the switch main body, one side of the first contact or the second contact is connected with the connecting piece, and the connecting piece is used to connect the outgoing line cable.

[0008] By adopting the above technical scheme, firstly, by arranging the connecting piece, when connecting the outgoing line cable with the disconnector, only one outgoing line cable needs to be connected with one connecting piece, which can be connected with the first contact and the second contact at the same time, thereby not only reducing the time consumed when connecting the outgoing line cable, but also reducing the use cost of the outgoing line cable; secondly, the connecting piece and the static contact can be quickly connected together, and it is convenient for people to operate, thereby improving the applicability of the structure.

[0009] Optionally, the connector includes a first connecting piece and a second connecting piece.

[0010] By adopting the above technical solution, the connector can be quickly installed on the outside of the stationary contact, which is convenient for people to operate. After installation, the first connecting piece and the second connecting piece are attached together and used to connect with the outgoing cable, thereby improving the practicality of the structure.

[0011] Optionally, a positioning block is fixedly connected to the upper side of the second connecting piece, and the first connecting piece has a positioning hole for the positioning block to be inserted.

[0012] By adopting the above technical solution, the stability of the connection between the first connecting piece and the second connecting piece can be guaranteed, and misalignment can be prevented when the first connecting piece and the second connecting piece are connected, thereby improving the service life of the structure.

[0013] Optionally, one end of the first connecting piece and the second connecting piece is provided with a first connecting hole for installing the outgoing cable.

[0016] By adopting the above technical solution, the connector can be quickly installed on the outside of the stationary contact, which is convenient for people to operate. This reduces the time spent connecting the outgoing cable to the disconnecting switch and improves the practicality of the structure.

[0017] Optionally, the connecting plate is provided with a bending portion, and the bending portion has a second connecting hole for installing the outgoing cable.

[0018] By adopting the above technical solutions, not only can the stability of the connection between the connector and the outgoing cable be guaranteed, but the service life and practicality of the connector can also be improved.

[0019] Optionally, a second fastener is provided at one end of the connecting plate away from the insertion rod, and a second through hole is provided at one end of the connecting plate for the second fastener to be screwed in, and the second through hole communicates with the insertion hole.

[0033] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0034] This application discloses an outgoing wire structure for an isolating switch.

[0035] Example 1:

[0036] Reference Figure 1 The disconnecting switch's outgoing cable structure includes a switch body 1 and multiple stationary contacts 2 mounted on the side of the switch body 1. Each stationary contact 2 includes multiple first contacts 21 mounted on the upper end of the switch body 1 and multiple second contacts 22 mounted on the lower end of the switch body 1. A connector 3 for connecting to the outgoing cable is installed between every two adjacent first contacts 21 and second contacts 22. The connector 3 allows a single outgoing cable to simultaneously connect to both first contacts 21 and second contacts 22. Two mounting plates 4 are mounted on the lower side of the switch body 1. The mounting plates 4 ensure the stability of the connection between the switch body 1 and objects or walls. In use, the switch body 1 is fixed to the wall or object by screws passing through the mounting plates 4; then, the connector 3 is installed on the outside of the first contacts 21 and second contacts 22; finally, the outgoing cable is fixed to one end of the connector 3, thus completing the connection between the outgoing cable and the switch body 1.

[0037] refer to Figure 1 , Figure 2The connector 3 consists of a first connecting piece 31 and a second connecting piece 32. Each end of the first connecting piece 31 and the second connecting piece 32 has a first through hole 34. A first fastener 33 passes through the inner wall of the first through hole 34, and the outer wall of the first fastener 33 is threadedly connected to the inner wall of the first contact 21 or the second contact 22. This fastener is used to fix the first connecting piece 31 to the outside of the first contact 21 or the second contact 22, and to fix the second connecting piece 32 to the outside of the first contact 21 or the second contact 22, thereby making one end of the first connecting piece 31 and one end of the second connecting piece 32 fit together. In this application, the first fastener 33 is a screw; in other embodiments, the first fastener 33 can also be a bolt, etc. In use, the first connecting piece 31 and the second connecting piece 32 are fixed to the outside of the first contact 21 or the second contact 22 by the first fastener 33, and then the outgoing cable is fixedly connected to the end where the first connecting piece 31 and the second connecting piece 32 meet.

[0038] refer to Figure 1 , Figure 2 and Figure 3 A positioning block 321 is fixedly connected to the upper side of the second connecting piece 32. The first connecting piece 31 has a positioning hole 311 for the positioning block 321 to be inserted. The positioning hole 311 and the positioning block 321 are used for quick connection between the first connecting piece 31 and the second connecting piece 32. One end of the first connecting piece 31 and the second connecting piece 32 has a communicating first connecting hole 35, which is used for the end of the outgoing cable to pass through, so that people can use screws or bolts to fix the cable to the joint end of the first connecting piece 31 and the second connecting piece 32.

[0039] The implementation principle of the disconnecting switch's outgoing wire structure in Embodiment 1 of this application is as follows: In use, firstly, one end of the second connecting piece 32 is attached to one side of the first contact 21 or the second contact 22; then, the first fastener 33 is passed through the first through hole 34 and screwed into the first contact 21 or the second contact 22, fixing the first connecting piece 31 to the outside of the first contact 21 or the second contact 22; next, one end of the first connecting piece 31 is attached to one side of the second connecting piece 32, so that the positioning hole 311 fits onto the positioning block 321. The outer side is then arranged so that one end of the first connecting piece 31 fits against one side of the first contact 21 or the second contact 22; next, the first fastener 33 is passed through the first through hole 34 of the first connecting piece 31 and screwed into the first contact 21 or the second contact 22 to fix the second connecting piece 32 to the outer side of the first contact 21 or the second contact 22; finally, a bolt or screw is passed through one end of the outgoing cable and through the first connecting hole 35 to fix the outgoing cable to the end where the first connecting piece 31 and the second connecting piece 32 are connected.

[0040] The difference between Example 2 and Example 1 is as follows:

[0041] refer to Figure 4 , Figure 5 and Figure 6 The connector 3 includes a connecting plate 36 and a plug 37 fixedly connected to one side of the connecting plate 36. Both the first contact 21 and the second contact 22 have insertion holes 23 for the plug 37 to be inserted. The plug 37 can be quickly inserted into the insertion holes 23 to quickly align the connecting plate 36 with the first contact 21 and the second contact 22, reducing misalignment during connection. The end of the connecting plate 36 opposite to the plug 37 has a second through hole 362. A second fastener 38 is connected to the inner wall of the second through hole 362, and one end of the second fastener 38 is threaded to the inner wall of the insertion hole 23, thereby fixing one end of the connecting plate 36 to one side of the first contact 21 or the second contact 22. In this application, the second fastener 38 is a screw; in other embodiments, the second fastener 38 can also be a bolt, etc. The connecting plate 36 is provided with a bending part 361, which is formed by bending and folding the middle part of the connecting plate 36, and a second connecting hole 3611 for installing the outgoing cable is provided at one end of the bending part 361.

[0042] In use, firstly, the connecting plate 36 is moved to insert the plug 37 into the socket 23 of the first contact 21 or the second contact 22 until the other end of the connecting plate 36 is in contact with the first contact 21 or the second contact 22; then, with the help of a tool, the second fastener 38 is passed through the second through hole 362 and screwed into the inner wall of the socket 23, thereby fixing the connecting plate 36 between the first contact 21 and the second contact 22; finally, one end of the outgoing cable is attached to one side of the bend 361 and wrapped around the outside of the bolt, and then the bolt is passed through the second connecting hole 3611 and fixed to the outside of the bend 361, or the outgoing cable is passed through the second connecting hole 3611 and wrapped around the outside of the bend 361, and then fixed in the second connecting hole 3611 with a bolt, thereby fixing the outgoing cable to the bend 361, thus completing the connection between the outgoing cable and the disconnecting switch.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
