Description

Exempt from to press auto-lock ammeter plugboard

Technical Field

The utility model relates to a termination, especially a exempt from to press auto-lock ammeter plugboard.

Background

The current common mounting method for the wiring of the electric meter is that the wire stripped of the insulating skin is directly inserted into a wire hole or is dipped in tin and then is screwed down by screws.

The disadvantages of this approach are: 1. the connecting screw is not firm when pressing the multi-strand wire, or the pressing is eccentric, so that the ammeter is easy to separate or connect in a virtual way, the contact resistance is increased, the temperature is increased, and the ammeter is easy to burn out; 2. the method is slightly rigorous in that the lead is pressed tightly by a screw after being soaked in tin and air-dried, the method is long in time consumption, inconvenient and low in efficiency, the air-dried lead is in an irregular round shape, and the screw is easy to slip and not pressed tightly when being pressed tightly, and the connection effect is not ideal.

As the prior art tends to integrate components such as an electric meter, an air switch and the like into the metering box, the metering box is convenient to overhaul and update. The connection mode in the prior art has the defects, so that the equipment in the metering box is large in contact resistance and high in temperature, is easy to burn out, and has obvious defects.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings in combination with the following embodiments. It should be noted that the embodiments and features of the embodiments of the present invention may be combined with each other without conflict.

It is to be understood that such description is merely exemplary and is not intended to limit the scope of the present invention.

Referring to fig. 1, 3 and 4, an embodiment of a voltage-free self-locking electric meter plugboard is shown, which comprises a board body 1 and a fixing portion for fixing the board body 1, wherein an installation portion 2 is arranged on the board body 1, a plurality of wiring terminals 3 are arranged on the outward part of the installation portion 2, an insertion port 4 which is electrically connected with the wiring terminals 3 and is used for being inserted into an electric meter is arranged on the inward part of the installation portion 2, and each wiring terminal 3 comprises a conical shaft 5 which can axially move inside the wiring terminal 3 and an elastic element which is abutted against the tail portion of the conical shaft 5. Because the installation part 2 is arranged on the plate body, and the insertion port 4 which is rapidly inserted into the ammeter is arranged on the installation part 2, the ammeter can be rapidly taken down or installed when being maintained or replaced, and the voltage-free wiring terminal 3 is installed in the installation part 2, so that the rapidness is further improved. In this embodiment, the connection terminal 3 includes a socket 13 having an inner cavity, and a wire hole socket 14, the wire hole socket 14 is installed at an opening of the socket 13, the taper shaft 5 is installed in the socket 13 and can move axially inside the connection terminal 3, and the wire hole socket 14 is used for passing in and out of a wire and limiting the taper shaft 5 from coming out of the connection terminal. The spring 15 is against the end of the cone shaft 5 and the bottom inside the terminal. When wiring, only the wire with the good insulation skin is required to be directly aligned to the tip of the conical shaft 5, the wire is rotated left and right and is inserted inwards, the wire completely enters the wiring terminal until the wire is stripped, and the wire is pressed in the gap between the inner wall of the wiring terminal and the outer surface of the tail of the conical shaft under the action of the spring 15, so that the pressure-free self-locking connection is realized. The connection mode is convenient to install and high in efficiency, and the special structure of pressure-free self-locking can lock the wire and simultaneously does not damage the wire, so that the connection effect is guaranteed; the multi-strand wire can evenly surround and distribute around the inside of the wiring terminal under the effect of the cone shaft, the current transmission is smoother, the contact resistance is lower, the temperature rise is low, the safety of the electric equipment can be greatly improved, the special characteristics of tight following and automatic clearance compensation can be realized, the electric equipment can be reliably used in a long-term high-frequency vibration environment, and the long-term stable and reliable operation of the electric equipment is ensured.

In order to further improve the maintenance and replacement speed and reduce the processing cost, the wiring terminal 3 and the insertion port 4 are processed into a whole. Because the wiring terminal and the inserting port 4 are integrated, the safety of electric connection is further improved.

Preferably, the mounting portion 2 is provided with a mounting hole 6 for mounting the terminal 3, and since the wire is inserted from a portion of the mounting portion facing outward, a pushing force is generated, and in order to prevent the terminal from being removed from the mounting portion, a locking hole 7 communicating with the mounting hole 6 is formed at the top of the mounting portion 2, a locking screw 8 is threadedly coupled to the locking hole 7, and when the terminal 3 is locked to the mounting portion 2, the distal end of the locking screw 8 abuts against the outer surface of the terminal 3. Adopt locking screw 8 fixed binding post 3, can prevent that binding post from droing, stable in structure is reliable, guarantees that current transmission is smooth and easy.

Preferably, the connecting terminals 3 are regularly arranged at the outward part of the mounting part 2, so that the processing is convenient and the appearance is attractive.

The fixing portion in this embodiment is a connection hole 9 for mounting the plugboard in the case of the metering box. The fixing portion may be other means commonly used in the art.

In this embodiment, the elastic element is a spring 15.

Fig. 2 shows an intelligent electric energy meter metering box provided with the above plugboard, which comprises a box body 10 and an electric meter 11, wherein the box body 1 is installed in the box body 10 through a fixing part, the electric meter 11 is plugged on the box body 1 through a connecting port 4, and then is screwed down by a screw 16, so that a virtual position is prevented from being connected between the electric meter and the plugboard, and the smoothness of current is ensured. A pressure-free self-locking air switch 12 is installed in the box body 10, and a wiring port of the air switch 12 can be provided with a wiring terminal consistent with the plug board, so that pressure-free self-locking connection is realized. The pressure-free self-locking technology is implanted into the plugboard and the air switch, the existing method of directly pressing the wire by using a screw is thoroughly abandoned, and the novel wiring mode has the characteristics of convenience and rapidness in installation, reliability in connection, low contact resistance, low temperature rise, no damage to the wire and the like. The whole connection effect is good, and the current transmission is guaranteed.
