Description

Wire and pipeline connectors

【Technical field】

The utility model relates to an electric wire pipeline connector, in particular to a socket fastening type wire pipeline connector.

【Background technique】

In the electrical installation and construction process in the construction field, wires and electronic components are generally installed in junction boxes. Under normal circumstances, the electronic components in the wires and junction boxes should not be exposed, otherwise they will be easily oxidized or damaged by external forces. In the prior art, multiple sections of pipelines such as steel pipes are usually used to cover the wires for shielding and protection, but this brings about the problem of how to solve the connection between the pipelines and the pipelines, and between the pipelines and the junction box.

For this reason, people in the industry have proposed a scheme of using connectors to realize the connection between pipelines and pipelines, and between pipelines and junction boxes. For example, the quick buckle type wire and pipeline connector disclosed in Chinese Patent No. 01255948.2 is positioned with ordinary set screws. Rotate the screw through the opening of the connecting piece until the head of the screw falls off, then it is determined that the wire pipeline and the connecting piece are fastened.

The above scheme can realize the connection between pipelines and pipelines, pipelines and junction boxes, but there are also the following serious shortcomings:

First of all, because this solution uses screws to fasten the wire pipeline and the connector, the force only acts on a certain point on the smooth cylindrical surface of the wire pipeline, with few contact surfaces and uneven force. Once the construction environment occurs Changes or damage from the outside often lead to loosening of the contact, easy slipping, and even lead to unsmooth electrical wiring.

Secondly, when the fastened wire pipeline needs to be disassembled for adjustment or maintenance, the screw head on the casing has fallen off when it was fastened for the first time, and the screw is for one-time use, so it cannot be simply It can be removed with a screwdriver, so its maintenance is quite troublesome.

【Content of utility model】

The purpose of this utility model is to overcome the above-mentioned shortcomings, add new technology, and provide a new process, which makes the combination of the wire pipeline and its connector more secure and safe, makes the conductivity of the pipeline better, and is also convenient for installation and maintenance.

The purpose of this utility model is achieved through the following technical solutions: the wire and pipeline connector includes a sleeve, the tail of at least one end of the sleeve is provided with a sleeve, and the tail of the sleeve corresponding to the sleeve is processed into an outer diameter The clamping band, which is smaller than the outer diameter of the casing tube, has at least one slot on it.

Compared with the prior art, the utility model has the advantages of changing the original point-contact fastening method of the casing to surface-bonded contact fastening because the collet uniformly acts on the surface of the cylinder in contact with it. The method makes it more firm and safe, so that the pipeline is better protected to ensure excellent conductivity. At the same time, it also avoids the disadvantage of inconvenient maintenance caused by unscrewing the head of the screw in the original technology.

Figure 2 is a longitudinal sectional view of the casing, the sleeve and the wire pipeline when they are fastened;

Fig. 3 is a three-dimensional view of the installation structure of another embodiment of the utility model;

【Detailed ways】

Please refer to Fig. 1, the electric wire pipeline connector of the present utility model comprises sleeve pipe 1, and the tail portion of this sleeve pipe 1 two ends is all provided with sleeve clip 3, and the tail portion of sleeve pipe 1 corresponding to sleeve clip 3 is processed to be smaller than The clamping band 12 on the outer diameter of the sleeve tube has at least one slot 14 on it. The sleeve clamp 3 is ring-shaped and not closed, and its two ends protrude outwards with a wing 32. The two wings are provided with corresponding internal thread openings 34 for the clamping screw 36 to pass through. Locating groove 16.

The sleeve clip of the present invention can also include a pair of clips, both ends of the clips protrude a wing, so that the clip is in the shape of "Ω", and each wing of the two clips is provided with a corresponding internal thread opening. Holes for screws to pass through.

Please refer to Figure 1 and Figure 2 together. When installing, first put the sleeve clamp 3 on the clamping belt 12 of the sleeve 1, then insert the wire pipeline 5 into the sleeve 1, and tighten the sleeve clamp 3 together. Clamping screw 36 on it makes it fasten and gets final product.

Please refer to Fig. 3, which discloses another embodiment of the utility model. The difference between this embodiment and the previous embodiment is that an internal thread through hole 18' is added on the casing 1', and the auxiliary screw 10' can be screwed into the through hole 18' and abutted against the outer wall of the wire pipeline (not shown), so that the connection between the wire pipeline (not shown) and the bushing 1' is more stable.

In addition to being realized in the above-mentioned manner, the electric wire pipeline connector of the present utility model can also be realized in the following ways corresponding to the connection between the wire pipeline and the junction box:

The bushing 1 has an externally threaded joint at the end, and has a claw-shaped lock nut with an internal thread and a hexagonal lock nut with an internal thread. The external thread matches.

When installing, the claw-shaped lock nut is buckled inside the junction box, and the claw-shaped lock nut and the hexagonal lock nut are clamped to the wall of the junction box with tools.

To sum up, the wire and pipeline connector of the utility model acts force evenly on the surface of the cylinder in contact with the sleeve clamp, changing the original method of simply using screw point contact fastening of the sleeve to screw and sleeve clamp The way of point-surface combined contact fastening makes it more firm and safe, so that the pipeline is better protected to ensure excellent electrical conductivity. The disadvantage of inconvenient maintenance. It is simple and convenient, practical and reliable.
