Abstract

The utility model relates to a clamp type socket-and-plug, which is composed of a plug and a socket. The plug comprises a plug box and a plug pin; the position which is adjacent to the wall of the plug box of the plug pin is provided with one or a plurality of depressed grooves; the jack of a socket cover is, the edge which is connected with a base of the socket cover is provided with at least one pair of concave-convex teeth which are mutually engaged. The utility model has high safety and reliability, and is especially suitable for the electrical appliances which moves frequently.

Description

Clamp type socket and plug

The utility model relates to a kind of socket plug.

Present normal domestic socket plug, no matter socket is single head socket or bull socket, the pin profile of plug is cylinder or cuboid, its result of use all has a common disadvantage, be exactly plug and socket loose contact, easily come off, even cause the damage electric equipment.

It is good that the purpose of this utility model is to design a kind of contact performance, the socket plug of difficult drop-off.Only need plug insertion socket is moved or twisting a little when the user needs the time spent, plug just firmly is stuck on the socket, spurs plug arbitrarily and also can not come off, and is safe in utilization.When need not to use, plug is oppositely moved gently or twists, the plug taking-up of just pitching.

The purpose of this utility model is achieved in that it is made of plug and socket, and plug includes plug box and pin, and pin is having one or more Baltimore grooves near near the plug box wall.Socket includes the spring leaf of installing in socket box and the box, and socket box is made up of socket cover and socket base.Jack shape on the socket cover is that upper and lower two ohm shape symmetries connect and compose.Simultaneously, be provided with the shaggy tooth that is meshed more than at least one pair of at the edge that socket cover links to each other with socket base.

Below in conjunction with drawings and Examples, structure of the present utility model is further described in detail.

Fig. 1 is the utility model cutaway view.

Fig. 2 is the utility model socket outline drawing.

Fig. 3 is the utility model plug outline drawing.

Fig. 4 is the outline drawing of design shaggy tooth on the utility model socket box shell.

Fig. 5 is the socket cut-away view.

Fig. 6 is plug interior structure figure.

Fig. 7 is single plugs and sockets user mode figure.

Fig. 8 is double plug socket user mode figure.

Referring to accompanying drawing, socket of the present utility model mainly is made of socket cover (1), socket base (2) and spring leaf electrode (3), and spring leaf (3) is fixed on the socket base (2) by screw (11).Socket box and plug box select for use plastics or other insulating material to make.

The main effect of socket base (2) is stationary spring and fixed installation socket, profile is cylindrical, oval or square, and adapt with socket cover, spring leaf (3) in the socket is an electrode slice, be used to connect power line and with the plug energized, select elasticity preferred metal sheet for use, better contact with pin so that make it.Plug is made up of plug box (4) and pin (5) two parts, and pin (5) is having one or more Baltimore grooves near near the plug box wall.Just can be blocked energized by socket cover when it inserts in the spring leaf in socket, the other end of pin connects power lead, the length of pin and size all with socket cover on jack adapt.

Fig. 5 and Fig. 6 are the socket plug cut-away view.(3) are the socket spring sheets among the figure, and fixedly usefulness one screw (11) of spring leaf is fixing, and (8) are the power line hand-holes, and (9) are the Nut column of fixed socket lid, and this Nut column is fixed as an integral body with socket base and socket cover.Use socket for the ease of fixed installation, design two above screw holes (10) on the base.(13) are aperture on the pin among the figure, are mainly used in the attachment plug power lead, and (14) are locking-type plug box screw hole.For energized effectively, a Screw (12) is housed on the socket spring sheet is used for fixing lead.

Fig. 7 and Fig. 8 are a user mode figure of single head and bull socket plug, and the jack on the socket cover (6) is shaped as upper and lower two ohm shape symmetries and connects and composes

Shape perhaps is

Shape.When being used for the single head plugs and sockets, the jack on the socket can be decided according to required, and the jack on socket cover (6) is shaped as During shape, the plug operation is twisting, for The time, the plug operation is to slide.For preventing that socket cover from rotating with plug, on socket base and edge that socket cover links to each other, be provided with the shaggy tooth (7) that is meshed more than at least one pair of, as shown in Figure 4.Socket cover can not rotate during the plug twisting.The jack of two kinds of shapes has same result of use.

The utility model should at first install and fix spring leaf in use, and power line is fixed in by the aperture on the socket on the Screw of mounted spring leaf, again the jack of socket cover and the spring leaf of socket base is aligned installation.Fastening socket cover screw can use.As need socket is fixed on other object, should the socket base that be provided with two above Screw holes is fixing earlier.And the installation method of plug is that the aperture on the pin in lead and the plug is connected firmly, and the plug box is closed, and fastening plug box screw can use.Time pin adds twisting or plug is moved gently along socket aperture with plug insertion socket as the user, and plug just firmly is stuck on the socket, and oppositely twisting or mobile plug can take out plug.These two kinds of socket working methods are illustrated in Fig. 7 and Fig. 8.Fig. 7 is plug twisting work, clockwise direction or counter-clockwise direction stressed all can, plug is subjected to m simultaneously ₁m ₂Plug just twists to clockwise direction during two power.Fig. 8 is plug slip work, and plug is along the socket aperture work that horizontally slips, and plug is subjected to external force m among the figure ₁Or m ₂The time, plug is just left or right the slip.After plug twisting or the slip work, plug is stuck in the socket.

The utility model using method is simple, safety, function admirable, and it has not only overcome the disadvantage of common socket plug, but also can be general with the common socket plug, and the electric equipment that is particularly suitable for normal shift position uses.

Claims
