Description

terminal block holder

technical field

The utility model relates to a wire end fixing device, in particular to a terminal fixing device.

Background technique

In power transmission, great attention is paid to lightning protection. In areas where lightning often occurs, lightning arresters are installed on many poles. The lightning arresters are grounded through wires. Buried a wire in the ground, and then connected in the middle, usually with a wire nose connection, the wire nose is the wire head (7) bent into a closed hole, as shown in Figure 1, the two wires are fixedly connected through the wire nose, This method not only wastes a large number of wires, but also consumes time and energy when connecting, and the work efficiency is very low.

Utility model content

The purpose of the utility model is to overcome the shortcomings and deficiencies of the above-mentioned prior art, provide a terminal holder, and solve the defects of wasting wires, time-consuming and labor-intensive in the existing lightning arrester and grounding wire connection method.

The purpose of this utility model is achieved through the following technical proposals: terminal holder, two clips made of metal, two wire grooves parallel to each other are respectively arranged on the two clips, two wire slots on each clip The grooves are all arranged on the same end face, and the wire grooves run through the corresponding clips in the direction of their extension, and the wire grooves on the two clips correspond one by one. At the same time, the end face of one clip provided with the wire groove is facing the end face of the other clip provided with the wire groove. This device is used to fix the lead wire and the ground wire of the arrester. The lead wire and the ground wire are staggered and placed in the two grooves of a clip respectively, and then the other clip is covered on the clip with the wire, and then used After the clamping device is fixed, the lead wire and the ground wire can be clamped by two clips, which saves time and effort.

Further, the above-mentioned clamping device includes at least two screw rods, all the screw rods are perpendicular to the wire groove and penetrate through the two clips respectively, nuts are screwed on the ends of the screw rods, and the two screws go through the two clips, ensuring that the clips do not It will twist, and then tighten the nut on the end to ensure that the two clips can clamp the lead wire and the ground wire.

Furthermore, all the above-mentioned screws are located on the same plane, and the two wire grooves on the same clip are symmetrical to the plane where the screws are located. The screw rod is located in the center of the wire groove, which ensures that the lead wire and the ground wire have the same pressing effect, and there will be no wire tightness. A thread is loose.

Further, the above-mentioned clip is made of steel, which not only ensures the electrical conductivity but also ensures the strength, and will not be broken.

Further, the above-mentioned clip is provided with reinforcing ribs, and the extending direction of the reinforcing rib is consistent with the extending direction of the wire groove, which strengthens the strength of the clip in the stretched direction and avoids the phenomenon of being broken.

The beneficial effects of the utility model are: the device facilitates the connection of the lead wire of the lightning arrester and the grounding wire, is very convenient to use, saves time and effort, and speeds up the work efficiency.

Detailed ways

Below in conjunction with embodiment the utility model is described in further detail, but the structure of the utility model is not limited to the following examples:

【Example 1】

As shown in Figure 2, Figure 3, and Figure 4, the terminal holder includes two clips 1 made of metal, and the two clips 1 are respectively provided with two parallel wire slots 2, each clip The two wire grooves 2 on 1 are set on the same end face, the wire groove 2 runs through the corresponding clip 1 in the direction of its extension, the wire grooves 2 on the two clips 1 correspond one by one, and the two clips 1 is connected and fixed by the clamping device 3, when the two clips 1 are connected, the end face of one clip 1 provided with the wire groove 2 faces the end face of the other clip 1 provided with the wire groove 2. In this embodiment, the clamping device 3 includes at least two screw rods 4, and all the screw rods 4 are perpendicular to the wire groove 2 and respectively penetrate through two clips 1, and the ends of the screw rods 4 are screwed with nuts 5, and the two screw rods 4 penetrate through two The clip 1 ensures that the clip 1 will not twist, and then tightens the nut 5 on the end to ensure that the two clips 1 can clamp the lead wire and the ground wire. All the screws 4 are located on the same plane, and the two slots 2 on the same clip 1 are symmetrical to the plane where the screw 4 is located. The screw 4 is located in the center of the slot 2, which ensures the same pressing effect of the lead wire and the ground wire, and there will be no one One thread is tight and one thread is loose. This device is used to fix the lead wire and the ground wire of the arrester. The lead wire and the ground wire are staggered and placed in the two wire grooves 2 of one clip 1, and then the other clip 1 is covered on the clip with the wires 1, and then fix it with a clamping device, the two clips 1 can clamp the lead wire and the ground wire, which is very time-saving and labor-saving.

In this embodiment, the clip 1 is made of steel, which not only ensures the electrical conductivity but also ensures the strength and will not be broken.

[Example 2]

As shown in Figure 5, the structure of this embodiment is basically the same as that of Embodiment 1, the difference is that further, the above-mentioned clip 1 is provided with a reinforcing rib 6, and the extending direction of the reinforcing rib 6 is consistent with the extending direction of the trunking 2, and the strengthening The strength of the clip 1 in the stretched direction is ensured, and the phenomenon of being pulled off is avoided.
