Description

Technical Field

[0001] The utility model relates to the technical field of wire connection, in particular to a wire auxiliary connection component. Background Technique

[0002] As an important material for transmitting electric energy, wires play an indispensable role in modern society. A wire refers to a conductor for transmitting electric energy, usually composed of one or several soft conductors, with a soft protective layer wrapped outside. According to different structures and uses, wires can be divided into various types, mainly including bare wires, electromagnetic wires, and insulated wires.

[0003] In modern society, insulated wires are the most widely used. When electricians connect electricity, it is often necessary to connect two sections of insulated wires. First, the insulating skins at the ends of the two wires are peeled off, then the wire parts are twisted together with pliers, and then tightly wrapped with insulating tape. Moreover, when the wires are twisted, the conductive parts are repeatedly twisted and stressed, and the toughness becomes poor under the action of stress, and it is easy to break, and the stability is poor. The insulating tape is also easy to age and fall off over time, which is dangerous. Content of the Utility Model

[0004] The purpose of the utility model is to provide a wire auxiliary connection component, which presses and connects the wires through fastening bolts, avoiding the problem that the twisted part of two wires in the prior art is easy to fall off and loosen under the action of tensile force, improving the stability of the connection. At the same time, the twisted ends of the wires are accommodated in the installation grooves of the main body made of insulating material, playing a good insulating and protective role. To achieve the above technical features, the purpose of the utility model is realized as follows:

[0005] A wire auxiliary connection component includes a main body. An installation groove is provided at the end of the main body. A receiving block is fixedly installed in the installation groove. Groove structures for placing wires are respectively opened on the upper surface and the lower surface of the receiving block. The two groove structures are distributed in a staggered manner, and the two groove structures are connected through a spiral receiving groove provided at one end of the receiving block. A fastening bolt corresponding to the groove structure is provided on the main body, and the end of the fastening bolt is introduced into the installation groove to press and fix the wires placed in the groove structure;

[0006] Both the main body and the receiving block are made of insulating materials.

[0007] The groove structure includes a first clamping groove opened at the end of the receiving block far from the spiral receiving groove and a second clamping groove communicated with the first clamping groove. The second clamping groove is communicated with the spiral receiving groove, and the first clamping groove and the second clamping groove form a stepped structure in combination. A transition part with a smooth curved surface structure is formed at the connection position between the second clamping groove and the first clamping groove and at the cross-section of the connection position between the first clamping groove and the spiral receiving groove.

[0008] The installation groove is provided with a concave spherical part near the spiral receiving groove side for facilitating the bending and turning of the end of the wire.

[0009] The number of the installation grooves is two, and the two installation grooves are respectively located at both ends of the main body.

[0010] The utility model has the following beneficial effects:

[0011] 1. By using the fastening bolt to tightly connect the wires and applying the above-mentioned bending structure, the problem that the twisted part of two wires in the prior art is prone to falling off and loosening under the action of tensile force is avoided, the connection stability is improved. At the same time, the twisted end of the wire is accommodated in the installation groove of the main body made of insulating material, playing a good insulating protection role.

[0012] 2. By designing the groove structure and combining the first clamping groove and the second clamping groove to form a stepped structure, and cooperating with the setting of the spiral receiving groove, different spans are formed in the horizontal and vertical directions when the wire is connected to the receiving block, which is beneficial to further improving the stability of the wire connection after connection.

[0023] An auxiliary wire connection member includes a main body 1. An installation groove 1a is provided at the end of the main body 1. A receiving block 2 is fixedly installed in the installation groove 1a. Groove structures for placing wires are respectively formed on the upper surface and the lower surface of the receiving block 2. The two groove structures are arranged in a staggered manner, and the two groove structures are connected through a spiral receiving groove 2a provided at one end of the receiving block 2. A fastening bolt 3 corresponding to the groove structure is provided on the main body 1. The end of the fastening bolt 3 is introduced into the installation groove 1a to press and fix the wires placed in the groove structures. Both the main body 1 and the receiving block 2 are made of insulating materials. During use, first, the insulating outer skins outside the opposite ends of the two wires to be connected are stripped off, and the exposed wire cores are twisted together with pliers. Then, the two wires are inserted into the installation groove 1a from the twisted end, and pass through the groove structure on the upper surface of the receiving block 2, the spiral receiving groove 2a, and the groove structure on the lower surface of the receiving block 2 in sequence to form a bending structure, and the twisted end of the wire is accommodated in the installation groove 1a. Subsequently, the fastening bolts 3 corresponding to the two groove structures are tightened respectively, so that the ends of the fastening bolts 3 are pressed against the outer sides of the insulating layers of the two wires to achieve locking. Through the pressing connection of the wires by the fastening bolts 3 and the application of the above bending structure, the problem that the twisted part of the two wires in the prior art is prone to falling off and loosening under the action of tensile force is avoided, and the connection stability is improved. At the same time, the twisted end of the wire is accommodated in the installation groove 1a of the main body 1 made of insulating material, which provides good insulation protection.

[0024] Further, the groove body structure includes a first clamping groove 2b opened at an end of the receiving block 2 away from the spiral receiving groove 2a and a second clamping groove 2c communicating with the first clamping groove 2b. The second clamping groove 2c communicates with the spiral receiving groove 2a, and the first clamping groove 2b and the second clamping groove 2c are combined to form a stepped structure. A transition portion 2d with a smooth curved surface structure is formed at the connection position between the second clamping groove 2c and the first clamping groove 2b and at the cross-section of the connection position between the first clamping groove 2b and the spiral receiving groove 2a. Through the above structure, when the wire is connected to the receiving block, different spans are formed in both the horizontal and vertical directions, which is beneficial to further improving the stability of the wire connection after connection. And by designing the cross-section part into a smooth curved surface structure, when the wire is pressed, the smooth curved surface structure is not easy to damage the wire, and at the same time, the fitting effect between the wire and the connection positions of the second clamping groove and the first clamping groove is improved, thereby ensuring the stability of the wire connection after connection.
