Description

Technical Field

[0001] This utility model relates to the field of cold shrink terminals, and in particular to an indoor cold shrink terminal for cables. Background Technology

[0002] Indoor cable cold shrink terminations are insulating and sealing components used for indoor connection or termination of power cables. Also known as cold shrink termination heads, their main function is to protect the cable ends, enhance insulation performance, prevent mechanical damage, and ensure the safe and stable operation of the power system.

[0003] In the existing technology, when applying cold shrink terminals to cables, cold shrink terminals of different lengths need to be customized according to the different lengths of cables, which results in poor versatility of the cold shrink terminals and affects work efficiency to a certain extent. In addition, the long cold shrink terminals are also inconvenient to carry, which causes some trouble for the work. Therefore, there is a need for an indoor cold shrink terminal for cables. Utility Model Content

[0004] The purpose of this utility model is to provide an indoor cold shrink terminal for cables. In this solution, the cold shrink terminal is designed to be interlocked, so that it can be used for cables of different lengths, which increases the versatility of the cold shrink terminal. Moreover, the reduced length of a single cold shrink terminal makes it easier to carry.

[0005] To achieve the above objectives, an indoor cable shrinking terminal is provided, comprising a shrinking terminal, a first connector, and a second connector. Two limiting rings are fixedly connected to the shrinking terminal, each with two positioning grooves. A connecting block is fixedly connected to the outer surface of the first connector, and a threaded rod is fixedly connected to the side surface of the connecting block. A nut is threaded onto the outer surface of the threaded rod. A mating block is fixedly connected to the outer surface of the second connector, and a positioning hole is provided on the mating block. A first sealing strip is fixedly connected to the side surface of the first connector, and a second sealing strip is fixedly connected to the side surface of the second connector. Two positioning blocks are fixedly connected to both the first and second connectors.

[0006] According to the aforementioned indoor cold shrink cable terminal, the positioning block is adapted to the positioning groove.

[0007] According to the aforementioned indoor cold shrink cable terminal, the threaded rod is adapted to the positioning hole.

[0008] According to the aforementioned indoor cold-shrink cable terminal, both the first sealing strip and the second sealing strip are made of rubber.

[0009] According to the aforementioned indoor cold shrink cable terminal, both the positioning block and the positioning groove are T-shaped.

[0010] According to the aforementioned indoor cold shrink cable terminal, the number of connecting blocks is two and they are symmetrically distributed.

[0011] According to the aforementioned indoor cold shrink terminal for cables, the number of threaded rods is two and they are symmetrically distributed.

[0012] According to the aforementioned indoor cable shrink terminal, the number of the mating blocks is two and they are symmetrically distributed.

[0013] The above-mentioned solution has the following beneficial effects:

[0014] 1. By setting up structures such as the first connector, the second connector, the positioning groove and the positioning block, the cold shrink terminal in this solution is designed to be dockable, so that it can be docked for use with cables of different lengths, which increases the versatility of the cold shrink terminal, and the reduced length of a single cold shrink terminal also makes it easier to carry.

[0015] 2. The design of the first and second sealing strips ensures a tight seal between the two cold shrink terminals, preventing moisture from the external environment from seeping into the interior of the cold shrink terminals through the joint, thus ensuring the protective effect of the cold shrink terminals.

[0016] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0025] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0026] Reference Figure 1-5 This utility model discloses an indoor cold-shrink cable terminal, comprising a cold-shrink terminal 1, a first connector 2, and a second connector 3. Two limiting rings 4 are fixedly connected to the cold-shrink terminal 1, each with two positioning grooves 5. A connecting block 6 is fixedly connected to the outer surface of the first connector 2, and a threaded rod 7 is fixedly connected to the side surface of the connecting block 6. A nut 8 is threadedly connected to the outer surface of the threaded rod 7. A mating block 9 is fixedly connected to the outer surface of the second connector 3, and a positioning hole 10 is provided on the mating block 9. A first sealing strip 11 is fixedly connected to the side surface of the first connector 2, and a second sealing strip 12 is fixedly connected to the side surface of the second connector 3. Two positioning blocks 13 are fixedly connected to both the first connector 2 and the second connector 3, and the positioning blocks 13 are adapted to the positioning grooves 5. The threaded rod 7 and the positioning hole 10 are connected to the positioning grooves 5. The first sealing strip 11 and the second sealing strip 12 are both made of rubber. The positioning block 13 and the positioning groove 5 are both T-shaped. There are two connecting blocks 6, which are symmetrically distributed. There are two threaded rods 7, which are symmetrically distributed. There are two docking blocks 9, which are symmetrically distributed. It should be noted that after the two cold shrink terminals 1 are docked, the side surfaces of the first connecting piece 2 and the second connecting piece 3 will contact the limiting rings 4 on the two cold shrink terminals 1 respectively. Under the action of the two limiting rings 4, the first connecting piece 2, the second connecting piece 3 and other structures can be prevented from moving up and down. In addition, the positioning groove 5 and the positioning block 13 are T-shaped, so they can prevent the two cold shrink terminals 1 from separating. Moreover, because rubber has excellent sealing performance, weather resistance and durability, the first sealing strip 11 and the second sealing strip 12 are made of rubber.

[0027] Working principle: By rotating the nut 8, the fixing between the first connector 2 and the second connector 3 can be released after unscrewing the nut 8 from the threaded rod 7. At this time, pulling the first connector 2 or the second connector 3 can separate the first connector 2 and the second connector 3, and at the same time, the first connector 2 and the second connector 3 can be removed from the cold shrink terminal 1, thus releasing the fixing between the two cold shrink terminals 1. When it is necessary to connect the two cold shrink terminals 1, first insert the positioning block 13 on the first connector 2 into the positioning groove 5 of the upper limit ring 4 of the two cold shrink terminals 1 respectively, so as to achieve the initial connection between the two cold shrink terminals 1. Then, insert the positioning block 13 on the second connector 3 into the positioning groove 5 of the upper limit ring 4 of the other side of the two cold shrink terminals 1. Furthermore, during the connection process of the second connector 3, the docking block 9 is inserted into the threaded rod 7 through the positioning hole 10 reserved on the docking block 9. Then, the nut 8 is screwed onto the threaded rod 7, thereby achieving the fixation between the first connector 2 and the second connector 3. At this time, the connection and fixation between the two cold shrink terminals 1 can also be achieved. After the two cold shrink terminals 1 are docked, the first sealing strip 11 and the second sealing strip 12 will fit against the connection of the two cold shrink terminals 1, thereby ensuring the sealing effect of the connection of the two cold shrink terminals 1 and preventing moisture from the external environment from seeping into the interior of the cold shrink terminals 1 through the connection between the two cold shrink terminals 1. When a longer cold shrink terminal 1 is needed, the above operation can be repeated to dock multiple cold shrink terminals 1.

[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
