Description

A two-way welding socket for high-voltage switch lead wire

technical field

The utility model relates to the technical field of sockets for cable connection, in particular to a two-way welding socket for high-voltage switch lead wires.

Background technique

At present, there are many types of pole-mounted switches that adopt a structural scheme in which the mechanism room and the gas box room are separated, while the current transformer and voltage transformer are installed in the gas room, and the secondary leads need to pass through the connection between the mechanism room and the gas box room. The plug socket leads to the institutional room. The so-called docking plug and socket refers to a plug and a socket, the socket is fixed on the device, and then the connection of the circuit is completed by plugging the plug. The style of the plug and the socket is shown in Figure 1.

Since the mechanism room is sealed, this connection point is also difficult to plug in and out, so the plug-in connection of the two parts of the plug and socket can be avoided, and a straight-through connection can be used, which can avoid poor contact between the two parts, wrong welding wires, and assembly Occupying a large space and other problems also saves parts and reduces costs. The voltage of the lead-out line of the high-voltage switch is relatively high, and it is difficult for ordinary sockets to meet the needs of use.

Utility model content

The purpose of the utility model is to provide a two-way welding socket for the lead wire of a high-voltage switch, which is used to solve the problems of poor contact and inconvenient use of the existing plug.

The technical solution adopted by the utility model to solve the technical problem is: a two-way welding socket for the lead wire of a high-voltage switch, which is characterized in that it includes a flange, and the flange extends to both ends to form a protruding ring. An insulator is inlaid inside the flange, and a plurality of conductive core feet are embedded in the insulator, and the conductive core feet extend to both ends to the outer end of the insulator.

The conductive core is a copper piece with an insertion hole, and wedge-shaped notches are provided at both ends of the conductive core to form a solder cup shape.

The outer end of the conductive core pin is flush with the protruding ring of the flange.

The two ends of the flange are respectively provided with sealing ring installation grooves.

The flange has bolt connection holes.

The beneficial effects of the utility model are: the technical solution of the patent is to use a two-way welded socket to replace the plug-in connection between the two parts of the original plug and socket. The utility model has the advantage that the conductive core pin is a straight-through structure, which reduces the contact resistance at the junction of the plug and socket, avoids the interruption of signal transmission due to poor contact, and also reduces the use of the plug. The original connection method requires The plug and the socket are two parts, but now only one part is needed for the socket, which saves materials and reduces product costs.

Detailed ways

As shown in Figure 2 to Figure 4,

A two-way welding socket for a high-voltage switch lead wire, which includes a metal flange 1 with bolt connection holes, the flange 1 extends to both ends to form a protruding ring 11, and the flange is provided with a connecting The hole 12 is respectively provided with a sealing ring installation groove 13 at both ends of the flange. The flange parts can be installed on the panel of equipment such as transformers through screws.

An insulator 2 is inlaid inside the flange, and a positioning ring 21 and a seal 22 are provided at the matching place. A number of conductive core feet 3 are embedded in the insulator, and the conductive core feet extend to both ends to the outer end of the insulator. The lugs of the flange are flush. The conductive core 3 is a copper piece with an insertion hole, and wedge-shaped notches 31 are provided at both ends of the conductive core to form a solder cup shape.

When using a two-way soldering socket, you only need to insert one end of the pre-welded wire into the solder cup of the corresponding contact according to the core pin number on the green insulator, and then solder with solder wire. There are cores on both sides of the insulator Pin size, to avoid welding errors, after welding at both ends, it can replace the original plug and socket.

Except for the technical features described in the instructions, all are known technologies by those skilled in the art.
