Description

a terminal block

technical field

The utility model relates to the technical field of electric power construction.

Background technique

Please refer to FIG. 1 and FIG. 2 , FIG. 1 is a schematic structural diagram of a connection terminal in the prior art; FIG. 2 is a right view of FIG. 1 .

As shown in Figure 1 and Figure 2, terminal block 01 is an accessory product used to realize electrical connection, and is applied to facilitate the connection of wires. In electric power construction, the use of terminal 01 is very common, and the construction site is almost everywhere. For example, when using cables, it is often necessary to make cable joints. It is necessary to remove the insulation layer at one end of the cable, and then insert it into the inner hole 02 of terminal 01. In the prior art, there has always been such a problem in the production of cable joints: in the process of removing the insulating layer, the length of the removed insulating layer is difficult to be exactly consistent with the length of the inner hole 02 of the terminal 01. If too much insulating layer is removed, the If the wire is exposed, it will be easily broken and damaged during later use; if the insulation layer is not removed enough, the contact distance between the wire and the terminal 01 will be insufficient. The production process often requires repeated pruning to overcome the above problems to a certain extent, so the production time is relatively long.

Therefore, how to improve the production efficiency of cable joints while avoiding the above technical problems is a technical problem urgently needed to be solved by those skilled in the art.

Utility model content

The technical problem to be solved by the utility model is to provide a connection terminal, which can save the production time of the cable joint and improve the production efficiency of the cable joint.

In order to solve the above technical problems, the technical solution adopted by the utility model is a connection terminal, which includes a cable joint end and an inner hole arranged in the cable joint end, the inner hole is used to connect with the cable, and the inner hole The hole is formed by a first hole near the inside and a second hole near the outside, the first hole communicates with the second hole, the diameter of the second hole is larger than the diameter of the first hole, and the first hole is connected to the second hole. One hole is used to accommodate the metal wire inside the cable, and the second hole is used to accommodate the part of the cable having an insulating layer.

Preferably, the first hole has a diameter of 11.5 mm and a length of 46 mm; the second hole has a diameter of 14 mm and a length of 14 mm.

The beneficial effects of the utility model are:

When the terminal provided by the utility model is used to make cable joints, the insulation part of the cable is allowed to be inserted, leaving a margin for the length error of the insulation layer removal, that is, after the production is completed, the part of the cable with the insulation layer is well packaged in the terminal , the metal wire part of the cable is not exposed, and in the later use process, it can avoid the direct extrusion of the metal wire at the end of the aperture to cause damage to the wire finger end, thereby avoiding overheating and burning due to wire damage. At the same time, because there is a margin for the length error of the insulation layer removal during the production process, it is not necessary to repeatedly trim the exposed length of the metal wire, which saves production time and improves the production efficiency of the cable joint.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.

Please refer to Fig. 3 and Fig. 4, the connecting terminal provided by the utility model includes a cable joint end 1 and an inner hole 2 arranged in the cable joint end 1, the inner hole 2 is used for connecting with a cable, and the inner hole 2 is formed by a The first hole 21 and the second hole 22 near the outside are formed, the first hole 21 and the second hole 22 are connected, the diameter of the second hole 22 is larger than the diameter of the first hole 21, and the first hole 21 is used to accommodate the cable inside The metal wire, the second hole 22 is used to accommodate the part of the cable with insulation.

When the terminal provided by the utility model is used to make cable joints, the insulation part of the cable is allowed to be inserted, leaving a margin for the length error of the insulation layer removal, that is, after the production is completed, the part of the cable with the insulation layer is well packaged in the terminal , the metal wire part of the cable is not exposed, and in the later use process, it can avoid the direct extrusion of the metal wire at the end of the aperture to cause damage to the wire finger end, thereby avoiding overheating and burning due to wire damage. At the same time, because there is a margin for the length error of the insulation layer removal during the production process, it is not necessary to repeatedly trim the exposed length of the metal wire, which saves production time and improves the production efficiency of the cable joint.

In the utility model, the diameter and length of the second hole are not limited, as long as it can accommodate the part of the cable with an insulating layer, specifically, taking the terminal of DTL-70 as an example, the diameter of the first hole is 11.5mm , the length is 46mm; the diameter of the second hole is 14mm, and the length is 14mm.

In this paper, specific examples are used to illustrate the principle and implementation of the present utility model, and the descriptions of the above embodiments are only used to help understand the method and core idea of the present utility model. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the utility model, some improvements and modifications can also be made to the utility model, and these improvements and modifications also fall into the protection of the claims of the utility model. within range.
