Abstract

The invention discloses a secure socket. Key points are that: two or three side edges of a plug bush are clamped on inner-layer plates of corresponding insulating plates respectively; the lower parts of the insulating plates are connected into a whole; the upper parts of the insulating plates are provided with double-layer plates at certain intervals; and the bottom edges of the inner-layer plates are connected with outer-layer plates, and the other three edges of the inner-layer plates are free edges. The structure of the conventional socket is partially improved without increase the cost of the product and changes in the use habits of a user, and the reliability of contact between a plug pin and the plug bush can be greatly improved.

Description

A kind of safety socket

Technical field

The present invention relates to a kind of single-phase socket.

Background technology

Single-phase socket involved in the present invention includes three receptacle electrical connectors of two receptacle electrical connectors and band earth jack.Though socket in the market is varied, their basic structure is roughly the same: promptly socket includes the last lower house of flexible connection, has one group of jack on the upper shell at least, and every group of jack can be two and also can be three; Above-mentioned jack can be a cylindrical void, also can be the irregularly-shaped hole that cylindrical void and circular hole are formed.In the socket cavity that last lower house is formed, be provided with the organize connecting element corresponding with every group of jack of upper shell.The above-mentioned connecting element of respectively organizing is again to be made up of the unit block that links to each other with binding post respectively; Each unit block is again by the S shape alcu alloy film sleeve composition of existing side by side with the vertical insulation board of upper shell end face and with insulation board and the base links to each other; Promptly two parallel insulation boards are arranged with cylindrical void corresponding cells assembly; Both relative faces are respectively established a S shape alcu alloy film of existing side by side with it, and both bases link to each other and constitute the sleeve that the cross section is shape of reverse omega, and the sidewall of its underpart contacts with insulation board; Two end limits on top are free state, and the opening of sleeve is corresponding with the jack of upper shell; With the corresponding unit block of irregularly-shaped hole; Except that two parallel insulation boards are arranged; Also be provided with another vertical with it insulation board in their sides; (towards the one side of other two insulation boards) is provided with the S shape alcu alloy film of existing side by side with it in this insulation board front, and its limit, upper end also is free state, and the shape of reverse omega alcu alloy film base between the parallel insulation board with two in this alcu alloy film base is connected as a single entity and becomes sleeve.During use, the metal of latch is inserted pawl and is inserted in the opening of above-mentioned sleeve, relies on the slotting pawl conducting electric current of self elastic force clamping of sleeve.Its weak point is: although sleeve generally all is to adopt resilient copper alloy, its elasticity is limited, in use; Because of very easily be out of shape by the effect sleeve of external force, opening size becomes greatly gradually, makes the bound fraction defective tightness of latch and socket; Produce loosening; Its consequence is to cause then that gently the electrical appliance sudden power influences operate as normal (cause that like sudden power computer data loses, its loss also can't be estimated), and is heavy then cause latch and the heating of sleeve contact position or produce electric arc; Burn socket, cause fire.

Summary of the invention

The object of the present invention is to provide safety socket a kind of simple in structure, safe and reliable.

The structure of socket of the present invention is identical with above-mentioned prior art socket major part, and just two or three above the sleeve hold the limit fixed-site in the unit block, and promptly they are stuck on the inner plating of corresponding with it insulation board.Above-mentioned insulation board bottom is connected as a single entity, and top is the doubling plate that certain intervals is arranged, and promptly the cross section of insulation board is the upper shed fork-shaped, and the gap of this inside and outside two-ply is the activity surplus that the inner plating strain leaves when inserting in the opening that pawl is inserted in sleeve for latch.In addition inner plating except that the base with lamina rara externa links to each other, its excess-three limit is that top margin is the free margins that does not link to each other with any object with dual-side, and the dual-side of lamina rara externa can link to each other with other objects.

During use, the latch metal is inserted pawl and is inserted in the opening of sleeve, and elastic force and two power actings in conjunction of primary insulation plate elastic deformation force that slotting pawl receives the sleeve alcu alloy film clamp it in conducting electric current.

The present invention compared with prior art has following advantage:

1, because sleeve and primary insulation plate are that no gap is slidingly matched, the sleeve opening size is able to guarantee that the contact engaging and separating force of each latch is even during product export.The present invention can guarantee that latch contacts with the tight of sleeve under the condition in certain useful life, and contact pressure is reliable more, lasting, has improved the safe application performance of socket greatly.

2, simple in structure, though only the part-structure that has socket now is improved, it can improve the quality of socket significantly, and does not change people's use habit.

Description of drawings:

Fig. 1 is that the user mode section of unit block of the present invention amplifies simplified schematic diagram.

Fig. 2 is that the master of unit block of the present invention looks section amplification simplified schematic diagram.

Fig. 3 be unit block of the present invention overlook the amplification simplified schematic diagram.

Among the figure: 1 represents sleeve, and 2 represent inner plating, and 3 represent insulation board, and 4 represent latch, and 5 represent the socket upper shell.

Embodiment: in the simplified schematic diagram of Fig. 1, Fig. 2 and safety socket unit block shown in Figure 3; This unit block is made up of the S shape alcu alloy film sleeve of existing side by side with the vertical insulation board of upper shell end face and with insulation board and the base links to each other; Should two parallel insulation boards be arranged with cylindrical void corresponding cells assembly; Both relative faces are respectively established a S shape alcu alloy film of existing side by side with it; Both bases link to each other and constitute the sleeve that the cross section is shape of reverse omega, and the sidewall of sleeve bottom contacts with insulation board, and two end limits above the sleeve are stuck on the inner plating of both sides insulation board.Above-mentioned insulation board bottom is connected as a single entity, and top is the doubling plate that certain intervals is arranged.Inner plating except that the base with lamina rara externa links to each other, its excess-three limit is free margins.The lamina rara externa dual-side is connected to form insulating cylinder with other two parallel insulation boards respectively.Above-mentioned two or three constitute one group of connecting element with the corresponding unit block that links to each other with binding post respectively again of one group of jack of upper shell respectively, and they are located in the socket cavity, and this socket has the last lower house of being processed by insulating material, and both flexibly connect.
