Cable connection joint

Technical Field

The invention relates to the field of cable connection, in particular to a cable connection joint.

Background

When the end part of the low-voltage cable is connected, a complex wiring process is needed, each line can be ensured to be connected, and short circuit between the lines is prevented. The common mode of manual winding and the mode of using a wiring terminal exist, whether the winding quality is consistent or not is difficult to ensure by manual winding, and the situation that the winding is not firm enough and is loosened can exist; although the use of the connecting terminal has high efficiency, the contact surface between the connecting terminal and the cable is small, and the pressure on the cable is high, so that the cable is easy to break or separate.

Although some cable connectors suitable for low-voltage environments exist at present, the connection modes are complex, and even the connection between the cables can be realized by means of special tools, so that the connection of the cables is very inconvenient.

Disclosure of Invention

In view of the above disadvantages in the prior art, the present invention provides a cable connector, which can achieve quick connection between cables, and is stable and firm in connection.

The scheme provided by the invention is as follows:

the cable connection joint comprises a base and a buckle cover, wherein cable grooves are formed in the base and the buckle cover, the base and the buckle cover can be buckled, the positions of the cable grooves are matched with each other after buckling, each cable groove is provided with a reel, the reel is provided with a through hole, the through hole is communicated with the cable grooves, and the reel is connected with a control device. The control device drives the reel, the reel enables the cables at two ends to be wound and connected and placed in the cable groove, the operation efficiency is improved, and meanwhile the cables can have high stability.

Preferably, the two ends of the cable groove are access ends, the middle of the cable groove is a stranded part, the width of the stranded part is larger than that of the access ends, and the through hole of the stranding wheel is communicated with the stranded part. Because the width of the cable in the middle part is increased after the cable is wound, the two ends and the middle part of the cable groove can better adapt to the width of the cable, and the bending and folding conditions of the cable in the cable groove are reduced.

Preferably, the through hole in the middle of the reel is a flat hole or two communicated round holes, and the round holes are communicated through a connecting channel with the diameter smaller than that of the round holes. When the reel rotates, it is required to ensure that the cable core passing through the through hole can rotate along with the reel, so that the cable can be wound and connected better.

Preferably, the pulleys are gears, and adjacent pulleys are meshed with each other. The mutually meshed reel wheels are convenient to operate, and synchronous rotation of all the reel wheels can be realized only by operating one of the reel wheels.

Preferably, the control device is a hand wheel which is meshed with the reel. One part of the hand wheel can extend out of the joint, so that an operator can operate the hand wheel conveniently.

Preferably, the base buckle closure all is equipped with the gear groove, hank wheel or hand wheel can be at the gear inslot internal rotation of buckle closure or one of base, and the gear inslot of another person is equipped with spacing tooth, spacing tooth and hank wheel or hand wheel can joint each other. The limiting teeth are used for clamping the reel, and after the buckle cover is buckled on the base, the limiting teeth clamp the reel to prevent the reel from rotating, so that the cable is prevented from being overturned due to pulling force or self elasticity, the cable is connected more firmly and is not easy to be disengaged. The base and the cover may be hinged or connected using a flexible plastic sheet.

Preferably, the base and the two ends of the buckle cover are respectively provided with a fixed pressing sleeve, and the base and the fixed pressing sleeves at the two ends of the buckle cover can be buckled. The fixed pressing sleeve is used for pressing the main cable when the buckling cover is buckled, so that the cable is not easy to bear force and is pulled out, the external pulling force applied to the cable core in the cable groove can be reduced, and the connection is more stable.

Preferably, the inner side of the fixed pressing sleeve is provided with a fixed bulge. The fixing protrusion can firmly bite the outer skin of the cable to prevent the cable from being pulled out.

The invention has the following beneficial effects:

1. the reel can replace the action of manually twisting the copper core of the cable and simultaneously complete the connection of a plurality of cables, so that compared with manual operation, the connection efficiency is improved, and the uniformity of the connection quality of each cable is conveniently ensured;

2. the reel can realize linkage and simultaneous rotation, simultaneously realize the connection of cables, and can prevent the reel from overturning after the buckle cover is buckled, so that the connection is firmer;

3. the fixed cover that presses can fix the bus cable, reduces the influence of outside pulling force to joint internal connection department, improves the stability of connecting.
