Description

The present invention relates to an extension cable module type switch socket connection structure, and more particularly to an improved connection structure between a switch socket and a connection member.

  In general, many housing or office sockets are provided at wall or corner positions and are not large in number. However, the power cables of electronic products are limited, and various types of electrical equipment products are only within a certain range. Can be used, causing various inconvenient situations, for example, causing difficulty when the user plans the indoor space, and causing problems such as poor indoor flow lines. In addition, with the development of science and technology and the growth of the economy, the types of electrical equipment products in daily life are increasing. For example, desktop PCs, LCD TVs, dryers, mobile phones, etc. are constantly increasing, and existing sockets are increasing. Many power extension cables have been designed to solve the problem because the amount of power is insufficient for use.

The basic structure of a conventional extension cable is generally composed of a plurality of switch sockets and connection members, and the connection between them is completed by a rivet method or a welding method. However, the rivet method is not firmly assembled and has the problem of causing poor conductivity due to looseness, and the welding method causes poor conductivity due to empty welding caused by insufficient amount of solder, or insufficient welding, There is a problem that leads to power interruption. Therefore, it is necessary to complete the assembly by a connection method that is more robust and reliable than the conventional method.

  In light of the above-mentioned drawbacks, the present inventors have actively engaged in improvement, and have finally developed the present invention through continuous trial manufacture and efforts to solve the above problems.

  An object of the present invention is to provide an extension cable type switch socket connection structure that uses and assembles rivets and welding methods simultaneously. The conventional extension cable switch is assembled by simply using rivets or simply using welding. However, since both of them have the disadvantages, the present invention aims to improve the defects of the conventional method. Has been submitted.

The present invention includes a switch socket and a connection member. The switch socket includes a shell, and a first contact clamp, a second contact clamp, and an electrical contact member provided on the shell, and each of the first contact clamp and the electrical contact member includes at least one riveting point. Is provided. The connection member includes a first conductive extension piece and a second conductive extension piece, both of which are provided with a plurality of riveting points, and are fastened to the riveting points on the first contact clamp and the electric contact member, respectively, and welded. Can be fixed.

  In the present invention, a base is installed on the bottom of the shell of the switch socket, and the first contact clamp and the second contact clamp can be provided on the base.

  In the present invention, the first contact clamp, the second contact clamp, and the electric contact member can be directly provided on the bottom of the shell.

  The feature of the present invention is that the rivet hole installed on the long side of the conductive circle and the riveting points on the plurality of switch sockets are fastened to each other and welded to fix the stability of the joint between the conductive elongated piece and the switch socket. The conductivity can be greatly increased. The disadvantage of simply using conventional rivets and not firmly connecting to the switch socket, or simply using welding and connecting to the switch socket can cause empty welding is avoided by the implementation method of the present invention. The present invention can greatly improve the yield and product quality during mass production.

  The features of the present invention can be clearly understood with reference to the drawings of the present invention and the detailed description of the embodiments.

  Referring to FIGS. 1, 2, and 3, the extension cable module type switch socket connection structure of the present invention includes a connection member 1 and a switch socket 2. Among them, the switch socket 2 includes a switch button 21 and a power supply module 22. A small spring 221, a large spring 222 and a contact piece 223 are further provided on the power supply module 22, and the power supply module 22 is switched by the switch button 21. The base 23 is provided below the power supply module 22, is connected to the power supply module 22, and has a long hole 231 at the center thereof (see FIG. 1). The first contact clamp 24 has a riveting point 241, is installed on one side of the base 23, is in contact with the small spring 221 of the power supply module 22, and the riveting point 241 is below the base 23. Protrusively. The second contact clamp 25 is provided on the other side of the base 23 and is in contact electrical connection with the contact piece 223 of the power supply module 22. The electric contact member 26 having the riveting point 261 is provided in the elongated hole 231 at the center of the base 23, and one end thereof engages with the elongated hole 231. Under the power supply module 22, the other end has a riveting point 261 and protrudes out of the long hole 231 of the base 23. The shell 27 is a hollow columnar body, is provided on the base 23, is tightly joined thereto, forms an accommodation space 271, accommodates the member therein, and the shell 27 Two openings 272 are provided, and the first contact clamp 24 and the second contact clamp 25 can be extended from the two openings 272 to the outside of the shell 27. Among them, the base 23 can form an independent member and can be assembled to the bottom of the shell 27. In the present invention, the bottom surface of the shell 27 can be directly sealed without installing the base, but the first contact clamp 24, the second contact clamp 25, and the electric contact member 26 are attached to the bottom of the shell 27. The structure is left in advance (not shown), thereby combining the first contact clamp 24, the second contact clamp 25 and the electrical connection 26 directly to the bottom of the shell 27.

  The connecting member 1 includes a first conductive extending piece 11, and a plurality of rivet holes 111 are provided on the connecting member 1. The connecting member 1 can be fastened to a rivet point 241 on the first contact clamp 24 and fixed by welding (the present invention).
