Description

Simple plug-in copper connecting pipe

Technical Field

The utility model relates to a power equipment technical field specifically indicates a simple and easy type plug-in copper is taken over.

Background

Copper connectors are a common device in the power industry and are mainly used for connecting conductors during cable butt joint. The traditional copper connecting pipe is shown in figure 1, and has the advantages of simple structure, good connecting effect and low manufacturing cost. In the actual operation and use process, one end of the cable is inserted into the copper connecting pipe, and the pressing pliers are used for pressing and connecting the cable by using a proper special tool, so that the operation is very simple. However, in order to facilitate the insertion of the cable, the inner diameter of the copper connecting pipe is required to be larger than the diameter of the cable conductor by 1-2mm, and the specification of the cable is various, and each kind of cable must have the copper connecting pipe with the corresponding specification because if the inner diameter of the copper connecting pipe is too large, the copper connecting pipe cannot be pressed by a special tool pressing clamp. In addition, if two cables of different specifications need to be butted, the conventional copper adapter cannot be used and must be customized, thereby increasing the cost.

Detailed Description

It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are used merely for convenience of description and for simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore, should not be construed as limiting the present invention. Furthermore, the terms "first", "second", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first," "second," etc. may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art through specific situations.

The utility model provides a simple and easy type plug-in copper is taken over, as shown in fig. 2, take over main part 1 including copper, be equipped with spliced eye 2 in the copper is taken over main part 1, be equipped with closing device in spliced eye 2.

Among the above-mentioned technical scheme, compress tightly the cable one end of inserting copper takeover main part 1 through the closing device who sets up in spliced eye 2, easy operation.

Furthermore, a plurality of annular grooves 3 are formed in the inner wall of the plug hole 2, and the pressing device is arranged in the annular grooves 3. By providing the annular groove 3, space is provided for the compression means to be mounted.

Specifically, as shown in fig. 3, the pressing device is a spring 4, and the spring 4 is disposed along the annular groove. The spring 4 is a compression spring, and two ends of the spring 4 are fixedly connected to form an annular structure.

In the above technical scheme, the compressibility of the spring 4 is utilized, so that the copper connecting pipe main body 1 can be suitable for cables with different diameters and different specifications, and the requirement that the diameter of the cable is smaller than the inner diameter of the plug hole 2 and larger than the inner diameter of the spring 4 with an annular structure is met. The cable butt joint device has the advantages of simple structure, reasonable technology, no convenient operation, suitability for the splicing of cables of different specifications, capability of completing the butt joint of the cables of different specifications, wide application range and very flexible application.

Further, the outer diameter of the spring 4 is the same as the width of the annular groove, and the outer diameter of the spring 4 is larger than the depth of the annular groove.

Specifically, the spring 4 is made of a copper alloy material. The spring 4 made of copper alloy has lower resistance and strong current transmission capability.

Specifically, the spring 4 has a hardness HV of not less than 140, and the pitch of the spring 4 is 1 to 5 mm.

Thereby the effect that compresses tightly of spring 4 has been improved, the fastness of ensureing the cable butt joint to improve the device's life, made it can compress tightly the cable of butt joint for a long time.
