Description

Internal electrical connection structure of socket and socket with this structure

technical field

The invention relates to a socket, in particular to an internal electrical connection structure of the socket and a socket with the electrical connection structure.

Background technique

The socket includes the shell and the electrical components and conductive strips arranged on the shell. The electrical components include sockets (sockets have two structural forms, modular and non-modular), terminals, indicator lights and switches, among which the socket is a necessary component, and the rest of the electrical components are Components are selectively set as required. The poles of electrical components (that is, L pole, N pole and E pole, and there is no E pole for ungrounded sockets) are connected together by conductive strips or wires to attract power. The switches, wiring terminals and indicator lights in the existing electrical components are connected with the conductive strips by riveting or welding, while the socket is not only welded and riveted, but also uses the plug in the socket ( Refers to the socket used to connect with the plug) connected to the conductive strip in an integral structure.

A socket is disclosed in the patent document with the Chinese patent number 022616977, the name "a switch with a socket", and the date of authorization announcement is November 5, 2003. The plug socket in the patent is riveted. connected to the conductor strip.

Welding and riveting have the advantages of reliable connection, but the existing welding and riveting methods require additional people or tooling tools to relatively fix the conductive strips and electrical components before performing welding and riveting operations, or the electrical components must be fixed first. Then hold the conductive sheet with one hand and perform the welding and riveting operation with the other hand in the socket shell, otherwise the position translation phenomenon will occur, so it is inconvenient to perform the welding and riveting operation.

In order to overcome the above-mentioned shortcomings of the welding and riveting operation, a connection structure in which the plug socket in the socket group is connected to the conductive strip in an integral structure has been designed. For example, in the patent document with the Chinese patent number 2010102873922, the authorized announcement date being September 26, 2012, and the title "a socket with one-piece conjoined socket", it is disclosed that a plug socket is integrated with a conductive strip. sockets connected together in a structural manner. There are following disadvantages in the connection mode of this kind of integrated structure: because the switches, terminal blocks and indicator lights in the socket all adopt the common parts on the market, that is, the parts that have been formed in advance and attract the power supply are the terminal pins, Therefore, this type of electrical component cannot be connected to the conductive strip in an integrated structure; when the socket is a five-hole socket, the distance between the two adjacent N pole sockets and the two adjacent L pole socket sockets The distance between them is very close, so it is very inconvenient to make a socket in the socket socket.

Contents of the invention

The present invention provides an internal electrical connection structure and socket that can be conveniently used to connect all electrical components in the socket with conductive strips, is convenient to connect, easy to manufacture, and reliable in connection, and solves the problem of the existing internal socket. The electrical connection structure cannot combine the advantages of good versatility, convenient connection, easy manufacture and reliable connection.

The above technical problems are solved by the following technical solutions: an internal electrical connection structure of a socket, the socket includes a flat conductive strip and an electrical component connected to the conductive strip, and is characterized in that it includes a Pins, and connecting sockets and welding through holes arranged on the conductive strips, the connecting sockets are integrated with the conductive strips, the connecting sockets and the conductive strips are distributed along the thickness direction of the conductive strips, The connecting socket includes a pair of elastic clips, and a "V"-shaped jaw inserted along the thickness direction of the conductive strip is formed between the pair of elastic clips, and the welding through hole is the same as the "V"-shaped jaw. Alignment, the pins are simultaneously passed through the welding through hole and the "V" shaped jaws and clamped by the pair of elastic clips. When in use, according to the number and position requirements of jacks, switches, indicator lights and wiring terminals in the socket, use conductive strips with corresponding numbers and positional relationships to connect sockets and welding through holes, and pass through the electrical components. The pins are inserted into the connecting socket and the welding through hole at the same time to realize the connection between the electrical component and the conductive sheet, and the welding through hole plays an auxiliary role in fixing the pin; if the pin is only inserted and cannot meet the connection strength requirements, it can be convenient Solder through holes are supplemented by solder. If there is only a two-pole socket group on the socket, the conductive strips in the socket only have the L pole conductive strip and the N pole conductive strip; if there is a three-pole socket in the socket, then the E pole conductive strip is also provided. After adopting this structure, it is not only convenient to make the connecting socket, but also can conveniently realize reliable and universal connection with all electrical components (if the connecting socket is arranged on the socket, the socket socket and the connecting socket need to be made on one substrate , It is very inconvenient to form), and the changes to other electrical components are small (except for terminals and sockets that need to add pins, some components themselves have pins).

Preferably, the pair of elastic clips are distributed along the width direction of the conductive strip, one end of the elastic clip is connected to the long surface of the conductive strip in an integral structure, and the welding through hole is A long hole extending along the length direction of the conductive strip, the pins are flat, and the width direction of the pins is consistent with the length direction of the welding through hole. It is convenient to make the connecting socket, and the structure is compact. It can increase the distance between the connecting socket and the adjacent conductive strip to improve the electrical insulation; it can make the contact area between the pin and the connecting socket large to reduce the contact resistance and The reliability during clamping is improved, and the influence of opening welding through holes on the structural strength of the conductive strip can be reduced.

Preferably, the width direction of the elastic clip is consistent with the length direction of the conductive strip. When the elastic clip is molded and connected to the sleeve, no distortion will occur on the long and wide surfaces, and the molding is more convenient.

Preferably, the elastic clip includes an introduction section, a clamping section and a second connecting section arranged sequentially from the free end, and the introduction section, the clamping section and the second connecting section are distributed along the thickness direction of the conductive strip, An introduction opening is formed between the introduction sections of a pair of elastic clips, and one end of the introduction opening away from the clamping section is wide and the other end is narrow. The conductive strips are connected together. The structure is simple, and it is convenient to insert the pins.

Preferably, a deformation opening is formed between the second connecting sections of the pair of elastic clips, and the deformation opening is wide at one end away from the clamping section and narrow at the other end. The clamping section can be elastically abutted with the pins reliably, and the socket sleeve is not easy to fail.

Preferably, the clamping section is an arc structure. When the pins are inserted into the connecting sleeve, the clamping section and the pins are in line contact, which saves labor when pulling out and inserting the pins.

As another preference, the clamping section is a linear structure. The clamping area between the socket and the pin can be increased.

As another preference, the elastic clip includes a clamping section, a first connecting section and a second connecting section arranged sequentially from the free end, the second connecting section is connected with the conductive strip, and the first connecting section The two connecting sections extend along the thickness direction of the conductive strip, the first connecting section is located between the two second connecting sections of a pair of elastic clips, and the clamping section is located between the conductive strip and the first connecting section A clamping opening is formed between the clamping sections of the pair of elastic clips, and the clamping opening is wide at one end away from the conductive strip and narrow at the other end. The elastic clamping effect is good, and the convenience when inserting the pin is better. This design is not easy to cause fatigue aging of the second connecting section when used, so when the clamping section is fatigued and the clamping force drops, it can be compensated by changing the inclination angle of the second connecting section, thereby extending the connecting sleeve effect on service life.

Preferably, a welding point is provided between the pin and the conductive sheet and connected together through the welding point, and the welding point is located in the welding through hole. The welding strength can be improved, and the solder joints can more reliably connect the pins and the conductive strips together without falling off.

A socket with an internal electrical connection structure of the socket, comprising a socket shell, the socket shell is provided with a flat conductive strip, an internal electrical connection structure of the socket and several electrical components, and the electrical components pass through the internal electrical connection structure of the socket Connected with the conductive strips, the internal electrical connection structure of the socket includes pins arranged on the electrical components, and connecting sockets and welding through holes arranged on the conductive strips, the connecting sockets are the same as the The conductive strip has an integrated structure, the connecting socket and the conductive strip are distributed along the thickness direction of the conductive strip, the connecting socket includes a pair of elastic clips, and a pair of elastic clips is formed between the pair of elastic clips along the thickness of the conductive strip. The "V"-shaped jaw inserted in the direction, the welding through hole is aligned with the "V"-shaped jaw, and the pins are simultaneously set in the welding through-hole and the "V"-shaped jaw and are inserted by the one Hold on to the spring clip.

The invention has the following advantages: design connecting sockets and welding through holes on the conductive strips to match the pins for electrical connection, enable electrical components to achieve matching with the least modification, good versatility, reliable connection, and convenient manufacture.
