Abstract

The utility model relates to an electric appliance socket in an alternating current power supply, particularly a common pin socket suitable for converting among the mainland, Hongkong, and Taiwan. The utility model comprises a socket seat body and three jacks which are distributed in isosceles triangle and are arranged on the surface of the seat body. The shape of the earth wire jack at the top end of the isosceles triangle among the three jacks is formed by combining a rectangular, a large circle, a small circle and a small rectangular in sequence. The shapes of the two jacks at the bottom end of the isosceles triangle among the three jacks are formed by turning connection and combination of a large rectangle and two small rectangles. Because the utility model increases the contact area between a pin and a plug sleeve, the plugging force of a three flat system is ensured, and simultaneously the defect that the lower width of a panel has to be widened in order to prevent a monopole from inserting according to the IEC standard and national standard requirement is solved, so as to achieve the purpose of saving exterior material.

Description

Multi-purpose socket

Technical field

The utility model relates to a kind of electrical equipment (AC power) socket, the conversion of Hong Kong and Taiwan's three ground common pin sockets in being particularly suitable for.

Background technology

General appliance socket at present has standard type and multi-purpose type socket two classes, standard type only is fit to the single shape plug of standard, owing to make the various criterion plug of electrical appliance area of source also different, this uses for the electric equipment of travelling, household or office usefulness and brings a lot of inconvenience.And the popular wider multipurpose socket of existing market (being commonly called as the general-purpose jack), because take into account the plug of various criterion, cause easily misplug into or the defect (CNS and international IEC standard do not allow to take place) inserted of one pole, it is owing to take into account more on the pass, require to make socket panel enough big for being fit to safety standard, cause the excessive defective of raw-material waste and volume.Simultaneously in order to take into account the compatibility of single jack, and produce flat slotting system latch and shortcoming (and the flat exactly slotting system of China's national standard) such as the sleeve contact area is not enough, contact engaging and separating force is not enough, so in use insert shakiness, easily come off, and the live part contact area causes in the use heating inadequately and easily even leads to fire, has the hidden danger of insecurity.

The utility model content

The purpose of this utility model is exactly for compatible not enough (unicity) that overcomes special-purpose jack and the insecurity of general-purpose jack, particularly for the flat plug system in many with jack in working condition deficiency and improved Multi-purpose socket is provided.

The technical solution of the utility model is achieved in that Multi-purpose socket comprises the socket pedestal and is located at three jacks that the pedestal surface is the isosceles triangle distribution, and the ground wire jack shape that is in the isosceles triangle top in described three jacks is to be combined by rectangle+great circle+roundlet+little rectangle successively; Two jack shapes that are in the isosceles triangle bottom in described three jacks are to be connected with three little rectangle break-ins by large rectangle to combine.

The utility model compared with prior art, owing to increased the contact area of latch and sleeve, guaranteed the contact engaging and separating force of three flat systems, solved simultaneously IEC standard and national standard require in for preventing that one pole from inserting the defect that must widen the following width of panel, thereby reach the purpose of saving the external form material.

Embodiment

Shown in figure Fig. 1-1 and Fig. 1-2, the utility model comprises the socket pedestal and is located at three jacks that the pedestal surface is the isosceles triangle distribution that the ground wire jack A shape that is in the isosceles triangle top in described three jacks is to be combined by rectangle+great circle+roundlet+little rectangle successively; Two jack B shapes that are in the isosceles triangle bottom in described three jacks are to be connected with three little rectangle break-ins by large rectangle to combine.

How the external form of pipe insert seat does not change, and the core of socket is jack forever, and the utility model is to insert modular system with CNS jack system, British Standard jack system, Unite States Standard jack system and Europe two circles to combine.Ground wire jack A shape in Fig. 1 is to be combined by rectangle+great circle+roundlet+little rectangle successively, can realize that the latch of said system ground wire inserts; The shape of jack B is to be connected with three little rectangle break-ins by large rectangle to combine, be characterized in two little rectangle dislocation of satisfying flat slotting system plug are separated, increase the contact area of flat slotting system plug and socket, while is owing to the position putting again, avoided traditional flat slotting combination bore excessive, the defective that the product shape width easily causes one pole to insert inadequately.

Specific embodiments of the present utility model is as follows:

1, can compatible part carry out overlapping combination for different plugs, notes are as 1. series of combination hole among Fig. 2 A, applicable as shown in Fig. 2 B English mark system and Europe superscript two system of circles plug of uniting.(black entity part is represented the corresponding standard latch).

2, how tradition is separated with the flat system common hole in the hole.With the 2. series of combination hole of Fig. 3 A, applicable GB three flat systems and Australia, New Zealand three flat systems shown in Fig. 3 B.Owing to separation that two flat system receptacle are misplaced from three flat systems, increased the 2. contact area of series of apertures, simultaneously owing to the increase of contact area, also guaranteed the contact engaging and separating force of three flat systems.

3, since with among Fig. 4 A 3. relative three flat slotting system holes, series of combination hole upwards move,, day mark flat and GB two flat inserting for plug that 3. series of apertures the was suitable for U.S.'s mark circle shown in Fig. 4 B, can increase contact area and reliability greatly, simultaneously, because 3. system moves separation from three flat system holes, solved IEC standard and GB require in for preventing that one pole from inserting the defect that must widen the following width of panel, thereby reach the purpose of saving the external form material.

4, with the contrast of traditional multipurpose socket: Fig. 5 A1 is the working conditions of traditional multipurpose socket three flat system plug when inserting.Fig. 5 A2 is the working conditions of the flat system plug of the utility model multipurpose socket three when inserting.The black entity is a latch, and the increase of contact site contact area can obviously be found out in the contact site on contrast latch and limit, hole.Fig. 5 B1 is the working conditions of traditional multipurpose socket two flat system plug when inserting.Fig. 5 B2 is the working conditions of the flat system plug of the utility model multipurpose socket two when inserting.Can obviously find out the increase of contact site contact area equally.

The minimum size requirement b that the minimum size of external molded breadth degree requires the one pole of a and this Multi-purpose socket to insert external molded breadth degree among Fig. 6 B from the one pole insertion figure of the traditional multipurpose socket of Fig. 6 A contrasts as can be seen, a has a surplus greater than one times of width of b, significantly explanation the utility model multipurpose socket than traditional multipurpose socket can do in actual applications littler, more save raw material.
