Description

Technical Field

[0001] This utility model relates to the field of power cable joint technology, and in particular to a connection joint structure for power cables. Background Technology

[0002] Connecting two sections of power cable or making an electrical connection between a power cable and equipment requires a connector. In order to achieve the necessary mechanical strength and protection and prevent external environmental factors from affecting the internal conductors of the power cable, prefabricated connectors are usually used. These are connector assemblies that are pre-assembled on the power cable. When in use, the connector is pressed together with force, and the rubber pad on one side is embedded into the groove on the other side, thus completing the sealing installation of the connector.

[0003] For example, Chinese patent application number CN 202420319794.7 discloses a power cable connector that is easy to connect, including connector one and connector two, which are detachably connected. A ring-shaped insert is connected to the right side of connector one, and a ring-shaped rubber pad is provided on the outer surface of the ring-shaped insert. A limiting groove is formed between the ring-shaped insert and the connector plug. A ring-shaped sleeve is connected to the left side of connector two, and a ring-shaped groove is formed on the inner wall of the ring-shaped sleeve. By squeezing connector one and connector two, the ring-shaped rubber pad is embedded into the ring-shaped groove, thereby achieving good sealing. However, in actual use, power cables inevitably experience system failures. During maintenance, this power cable connector needs to be completely cut or replaced, and then the multi-layer structure needs to be peeled off and reinstalled, resulting in long maintenance time and high costs. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a connection joint structure for power cables to solve the technical problem that in the maintenance process of existing technology, the power cable joint needs to be cut or replaced as a whole, and then the multi-layer structure needs to be peeled off and reinstalled, which results in long maintenance time and high cost.

[0005] To achieve the above objectives, this utility model provides a connection joint structure for a power cable, including a detachably connected joint one and a joint two. A cable body is connected to the left side of joint one and the right side of joint two. Both joint one and joint two are placed within a connecting seat. Limiting arc plates are provided on both sides of the connecting seat, and a sealing groove is provided in the middle of the connecting seat. A limiting protrusion is provided at the connection point of joint one and joint two. The connection joint structure further includes:

[0006] A flip-up part is provided on the connecting seat, one end of the flip-up part is hinged to the connecting seat, and the other end of the flip-up part is bolted to the connecting seat. A limiting groove is provided on the inner surface of the middle part of the flip-up part, and the limiting groove cooperates with the limiting protrusion.

[0007] After the limiting protrusion disengages from the limiting groove, the first connector and the second connector can slide between the two limiting arc plates of the connecting seat.

[0008] Furthermore, the connector is provided with two cable bodies.

[0009] Furthermore, the flipping portion includes:

[0010] An arc-shaped cover plate is hinged to the connecting seat at its upper end. The arc-shaped cover plate is hinged to the connecting seat through a hinge interface, which is hidden inside the connecting seat.

[0011] A stepped protrusion is provided at the lower end of the arc-shaped cover plate;

[0012] Rubber arc plates are provided on both sides of the arc-shaped cover plate.

[0013] Furthermore, the stepped protrusion cooperates with the sealing groove, and the rubber arc plate cooperates with the limiting arc plate.

[0014] Furthermore, the connecting seat has a through hole in the middle, and a guide plate is provided in the through hole. The connecting seat is adjustablely mounted on the guide plate by fastening bolts.

[0015] Furthermore, the connecting seat is a detachable structure, including an upper seat and a lower seat. The upper seat is hinged to one end of the flipping part, and the lower seat is connected to the upper seat by bolts.

[0016] Furthermore, the first connector is provided with a plurality of plugs, and the second connector is provided with a plurality of slots, the slots cooperating with the plugs.

[0017] Furthermore, the first connector is provided with a guide post in a circumferential direction, and the second connector is provided with a guide hole in a circumferential direction, with the guide post cooperating with the guide hole.

[0018] The beneficial effects of this utility model are as follows: In use, it can enclose and protect the entire connector one and connector two and the corresponding cable body. During maintenance, the flipping part can be opened from the connector seat, so that the limiting protrusion is disengaged from the limiting groove, thereby allowing connector one and connector two to slide between the two limiting arc plates of the connector seat. The flipping of the flipping part can also make the connector seat partially open, which makes it easy to separate connector one and connector two within the connector seat and perform quick and convenient maintenance on each one without the need for overall cutting or replacement, thus reducing maintenance time and cost.

Figure 1-5 As shown, the connector includes a detachable connector 1 and a connector 2. Cable bodies 3 are connected to the left side of connector 1 and the right side of connector 2. Both connector 1 and connector 2 are placed within a connector seat 4. Limiting arc plates 5 are provided on both sides of the connector seat 4, and a sealing groove 6 is provided in the middle of the connector seat 4. A limiting protrusion 7 is provided at the connection point between connector 1 and connector 2. The connector structure also includes:

[0030] A flipping part is provided on the connecting seat 4. One end of the flipping part is hinged to the connecting seat 4, and the other end of the flipping part is bolted to the connecting seat 4. A limiting groove 8 is provided on the inner surface of the middle part of the flipping part, and the limiting groove 8 cooperates with the limiting protrusion 7.

[0031] After the limiting protrusion 7 disengages from the limiting groove 8, connector 1 and connector 2 can slide between the two limiting arc plates 5 of the connecting seat 4.

[0032] In this embodiment, during use, the flipping part is fixed to the connecting seat 4 by bolts. The limiting protrusion 7 at the connection between connector 1 and connector 2 is placed in the limiting groove 8 on the inner surface of the middle part of the flipping part to limit and fix the connector 1 and connector 2 as a whole and the corresponding cable body 3 in the connecting seat 4. The limiting arc plates 5 on both sides of the connecting seat 4 and the sealing groove 6 in the middle of the connecting seat 4 are used to seal and protect the connector 1 and connector 2 as a whole and the corresponding cable body 3.

[0033] During maintenance, the flipping part is opened by flipping the connector 4, so that the limiting protrusion 7 is disengaged from the limiting groove 8, thereby allowing connector 1 and connector 2 to slide between the two limiting arc plates 5 of the connector 4. The flipping part can also make the connector 4 partially open, which makes it easy to separate connector 1 and connector 2 within the connector 4 and perform quick and convenient maintenance on each one without the need for overall cutting or replacement.
