Description

Technical Field

[0001] The utility model relates to the technical field of fireproof cables, in particular to a fireproof cable with a quick connector and a positioning piece. Background Art

[0002] The requirements for the safety performance of cables are getting higher and higher, and the use of fire-resistant cables is also increasing. At present, the most widely used fire-resistant cables are mainly UL series flame-retardant cables and flame-retardant low-smoke halogen-free cables. Connectors are required for connection during the connection process.

[0003] After searching, the utility model with announcement number CN217656179U discloses a fireproof cable with a quick connector. By setting a limit block and a limit groove for use, the limit block is inserted into the limit groove to limit the two connectors. The connectors can only move along the track of the limit block and the limit groove, which solves the problem that the existing fireproof cables are mostly connected by screws and nuts, and are generally installed by tools or hand tightening, which makes the installation too cumbersome during the operation.

[0004] The connector also has the following disadvantages during use: the line connection is achieved by plugging the connector into the connector during use, but because the connector and the connector are hollow, they are easily clogged with dust when not used for a long time, which affects the plugging when used again. Utility Model Content

A fire-proof cable and a positioning member with a quick connector are proposed.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A fireproof cable with a quick connector comprises a wire body, wherein the wire body is composed of an insulating shell, a heat insulation layer, a fireproof layer and a wire core which are sequentially arranged from outside to inside;

[0010] The blocking mechanism is arranged at one end of the first joint and is used for blocking the one end of the first joint.

[0011] In a possible design, a plurality of clamping columns are fixedly provided at one end of the first connector, and a clamping slot for use with the clamping columns is opened at one end of the second connector. After the clamping slot is inserted and rotated, the first connector and the second connector can be limited.

[0012] In a possible design, the blocking mechanism includes a conductive plate slidably disposed in the first joint, a conductive column is fixedly disposed on the inner side of the conductive plate, and a socket corresponding to the conductive column is formed at one end of the first connecting tube.

[0013] In a possible design, an arc-shaped groove is provided in the first joint, a rubber pad is provided in the arc-shaped groove, an inner end of the rubber pad is fixedly connected to the first connecting tube, and the other end of the rubber pad is fixedly connected to the conductive plate to provide resetting power for the conductive plate.

[0014] In a possible design, the insulating shell is made of aluminum oxide.

[0015] In a possible design, the thermal insulation layer is made of rock wool.

[0016] In a possible design, the fireproof layer is made of glass fiber.

[0017] A positioning piece includes the above-mentioned second joint, the outer wall of the second joint is provided with a threaded groove, a nut ring is threadedly sleeved on the threaded groove, a connecting ring is sleeved on the outer wall of the threaded groove, the connecting ring is rotatably arranged at one end of the nut ring, a limiting column is slidably provided in the clamping groove for positioning the clamping column, and a plurality of the limiting columns are fixedly arranged at one end of the connecting ring.

[0018] In the present application, when in use, the first connector is inserted into the second connector, and the conductive plate can be driven to move during the insertion process, and the rubber pad is compressed until the conductive column is inserted into the socket, at which time the card column is inserted into the corresponding card slot, and then the first connector or the second connector is rotated to move the convex part of the card column into the card slot, and at this time the first connector will not be separated from the second connector;

[0019] Then rotate the nut ring to move the nut ring on the threaded groove. During the movement, the limiting column can be pushed to move through the connecting ring, so that the limiting column moves to one side of the clamping column, and the clamping column is fixed in the clamping groove so that it will not move, thereby improving the connection stability.

[0020] Beneficial effects:

[0021] In the utility model, the fireproof cable with a quick connector can automatically seal one end of the first connector after disconnection through the coordinated use of a conductive plate and a rubber pad, so that impurities such as soil will not enter, which is convenient for subsequent use;
