[0001] The utility model belongs to the technical field of cable fixing, in particular to a wiring nose. Background Art

[0002] The terminal lug, also known as the wire lug, copper lug, copper terminal, terminal lug copper joint, etc., is often used for cable end connection and continuation, which can make the cable and electrical connection more firm and safer. It is a commonly used material for construction, power equipment, and electrical connection. When the general wire is connected to the terminal, the corresponding wiring connection terminal must be used in accordance with the national wiring specifications. If it is a multi-strand copper wire with a diameter of more than 4mm, a wiring lug must be installed and then connected to the terminal.

[0003] At present, the cable connection end of the traditional wire nose, also known as the copper wire nose, is a hollow tube structure. After the copper wire is inserted, it needs to be crimped with hydraulic pliers to ensure that the copper wire is in close contact with the inner wall of the hollow tube. The problems with the traditional copper wire nose are: first, it cannot be reused, and the hydraulic pliers cause irreversible deformation to the hollow tube. When replacing or lengthening the cable, the copper wire nose is scrapped and cannot be used again; second, when there are a large number of copper wires, it is not easy to insert them into the copper tube. Other auxiliary equipment is needed to bundle and organize the copper wires before they can be inserted. The process is cumbersome and inefficient.

[0004] Based on the above analysis, the present application designs a wiring nose for connecting cables which has a simple structure and is easy to use. Utility Model Content

It should be emphasized that the following description is merely exemplary and is not intended to limit the scope of the present invention and its application.

[0022] like Figure 1 The copper wiring nose provided in the present embodiment comprises a wiring terminal 2 and a fixed terminal 1, the wiring terminal 2 comprises a hollow tube 21 and a fastening sleeve 22, the hollow tube 21 and the fastening sleeve 22 are made of copper alloy material, and of course, they can also be made of metal materials such as iron and aluminum; a plurality of through slots 23 starting from the end and extending along its axial direction, i.e., longitudinal direction, are provided on the tube wall of the hollow tube 21, and the plurality of through slots 23 divide the tube wall of the hollow tube 21 into multiple petals, so that or form an expandable multi-grip structure at one end of the hollow tube 21 close to the end; in the present embodiment, preferably but not limited to, three through slots 23 are provided, and the three through slots 23 are equidistantly arranged on the tube wall of the hollow tube 21 and divide the end of the hollow tube 21 close to the end into a three-grip structure; the three-grip structure is in an expanded state under normal conditions, or enters an expanded state under the action of external force; in the present embodiment, the end of the hollow tube 21 is provided with It is a three-claw structure, which is convenient for inserting multiple copper wires compared to the traditional closed tubular structure. There is no need to use additional auxiliary equipment to bundle and organize the multiple copper wires, which effectively improves the cable plug-in efficiency and simplifies the plug-in process; the fastening sleeve 22 is sleeved on the hollow tube 21, and the fastening sleeve 22 can tighten the multi-claw structure at the end of the hollow tube 21 to ensure that the copper wire is in close contact with the inner wall of the hollow tube 21; in this embodiment, the fastening sleeve 22 can be a closed sleeve structure, or it can be formed by docking a plurality of clamping hoop plates. When it is a closed sleeve structure, after the copper wire is plugged into the hollow tube 21, the operator can pinch the multi-claw structure of the hollow sleeve with one hand to sleeve the sleeve; when it is formed by docking the clamping hoop plates, after the copper wire is plugged into the hollow tube 21, each clamping hoop plate is connected to a locking state through buckle ears, wherein the locking degree can be selected according to the thickness of the copper wire bundle to ensure that the copper wire is in close contact with the inner wall of the hollow tube 21.

[0023] In this embodiment, the width of the through slot 23 is preferably 8-15 mm, which can be determined according to the diameter of the hollow tube 21 and the actual expansion state, and is not specifically limited in this embodiment.

[0024] In order to facilitate the adjustment of the locking degree and the locking operation, the fastening sleeve 22 of this embodiment is preferably composed of a hoop plate, specifically including a first hoop plate and a second hoop plate, such as Figure 1-2 As shown, the first hoop plate and the second hoop plate are both semicircular structures, and buckle ears are respectively provided thereon, and the buckle ears between the two hoop plates are connected by multiple groups of bolts; after the first hoop plate and the second hoop plate are butt-jointed, a sleeve structure with a diameter less than or equal to the outer diameter of the hollow tube 21 can be formed.

[0025] In this embodiment, whether the fastening sleeve 22 is a sealed sleeve structure or a clamp combination structure, there is a problem of low sleeve efficiency when the actual sleeve is tightened. In this regard, in this embodiment, an external thread 24 is provided on the outer wall of the hollow tube 21, and an internal thread is provided on the inner wall of the fastening sleeve 22, and the inner cavity of the fastening sleeve 22 is a conical structure with a larger upper part and a smaller lower part (it can be understood that the larger upper part and the smaller lower part are limitations made for the specific description of the inner cavity structure of the fastening sleeve 22, that is, the upper end and the lower end are relative terms, and there is no substantial limitation on the structure of the fastening sleeve 22, nor on the use of the fastening sleeve 22. It is specifically determined according to the actual situation which end of the fastening sleeve 22 is defined as the upper end). Figure 3-4 As shown, the fastening sleeve 22 is connected to the hollow tube 21 by a screw connection and spinning method and fastens it; specifically, when the fastening sleeve 22 is a closed sleeve structure, the multi-grip structure end of the hollow tube 21 is manually pinched, and then the end with a larger inner cavity size of the fastening sleeve 22 is first docked with the multi-grip structure end of the hollow tube 21, and then the sleeve is rotated, and the sleeve is screwed into the hollow tube 21 by a screw connection method, and as the inner cavity size of the sleeve decreases, the compression operation is performed until the required tightness is met; when the fastening sleeve 22 is a clamp combination structure, each clamp can be firstly The sleeve is combined on the hollow tube 21 to form a sleeve, and then the sleeve is rotated to move left or right on the hollow sleeve 21, and then the multi-grip end of the hollow sleeve is tightened by the smaller end in the inner cavity of the fastening sleeve 22 until the required tightness is met; it can be seen that the present embodiment sets the fastening sleeve 22 as a conical structure and cooperates with the screw connection method to achieve rapid fastening of the multi-grip structure on the hollow tube 21. Compared with the hard sleeve connection and multiple sets of bolt locking methods, this method of the present embodiment can not only further improve the fastening efficiency of the fastening sleeve 22 for the multi-grip structure, but also saves labor.

[0026] In this embodiment, the fastening sleeve 22 replaces the traditional hydraulic pliers crimping method. The use of the fastening sleeve 22 will not cause irreversible damage to the hollow tube 21. When changing the line or lengthening the cable, the end of the hollow tube 21 can be restored to the expanded state by removing the fastening sleeve 22 or adjusting the position of the fastening sleeve 22 on the hollow tube 21, thereby realizing the reusable use of the copper wire nose.

[0027] From the above analysis, it can be seen that the copper nose wire of this embodiment has a simple structure and is easy to operate, which can effectively improve the plug-in efficiency of the copper wire. At the same time, it can be reused, which reduces the use cost of the copper wire nose and has certain practical and market value.
