Abstract

The utility model relates to a power plug, which is mainly characterized by comprising a contact switch. A pressing post of the contact switch is fixed on a casing cover through a return spring, an upper contact binding post is arranged at the end of the pressing post, and a lower contact binding post under the upper contact binding post is arranged on a casing seat and connected with a pin. The power plug has the advantages of having a control function, thereby improving operation performance of equipment.

Description

Attaching plug

Technical field

The utility model relates to electric component, is a kind of attaching plug.

Background technology

As everyone knows, electric equipment all disposes attaching plug, and common attaching plug consists predominantly of cap, pin and fixes the shell block of this pin.Be inserted in the corresponding supply socket with this plug (two-phase, three-phase or four phases), promptly realize electric equipment is powered.Like this attaching plug of structure only has the function of supplying power of connection and does not have other.

Summary of the invention

The purpose of this utility model provides a kind of attaching plug that also has controlled function, for the action need of electric equipment under some special purposes or the environmental condition.

Realize the utility model of above-mentioned purpose, the same shell block that consists predominantly of cap, pin and fix this pin with conventional attaching plug, characteristics of the present utility model are, also include a touch switch, said touch switch comprises and is arranged on one on the cap by post, a return spring, a upper contact binding post be located at a next contact binding post on the shell block, the corresponding setting of upper and lower contact binding post; Saidly be installed on the cap by return spring by post, upper contact binding post is connected this by column end; Said the next contact binding post is connected with a pin.Said attaching plug like this, during use a control signal wire by the specific (special) requirements setting on the electric equipment is connected on the upper contact binding post of this plug, when pressing when the upper contact binding post of its end being contacted with the next contact binding post by post, can realize a certain controlled function of electric equipment is raising quality of the present utility model, as enable to observe attaching plug work normally whether, and be connected to fuse holder according to the order of sequence for the security performance the utility model that ensures electric equipment may be implemented in live wire pin binding post, pipe and resistance and indicator light are to the zero line binding post.

The utility model is fixed on the binding post of the pin on the housing seat can be by two, three or four, i.e. the utility model design can be used for two-phase, three-phase, four equates multiple attaching plugs.Major advantage of the present utility model is: make this power pin line binding post fuse holder, pipe and resistance and indicator light be arranged according to the order of sequence to the zero line binding post owing to set up a manual touch switch, the utility model also has advantages such as safe, directly perceived.

Embodiment

Preferred embodiment of the utility model is a kind of three phase mains plug as shown in Figure 1.See by figure, present embodiment comprises a cap, three pins 8 and fixedly in housing seat 7. present embodiments of pin 8, being installed on the cap 1 by return spring 3 of touch switch by post 2, be connected with a upper contact binding post 4 in this end by post 2, be provided with a next contact binding post 5 on the housing seat 7 under upper contact binding post 4, this next contact binding post 5 is connected with a pin 8.Present embodiment also is connected to fuse holder pipe 9 and resistance, indicator light 6 to zero line N binding post 8 according to the order of sequence at live wire L pin binding post 8.

Figure 2 shows that the another kind of element connected mode of three-phase power socket embodiment.By figure, identical with above-mentioned case connected mode, respectively have a label at the top of three pins and be respectively 10,11,12 binding post, and be connected with ground wire N and fire, zero line L, N respectively, on live wire L binding post 11, be connected with a next contact binding post 5.And between fire, zero line L,

N binding post

11 and 12, also be connected with an indicator light 6 (see figure 3)s by a resistance 14.

Figure 4 shows that another element connected mode of three-phase power socket embodiment.See by figure, respectively have a label at the top of three pins and be respectively 10,11,12 binding post, zero line N binding post 12 is connected with ground wire E with zero line N respectively with ground wire E binding post 10, the next contact binding post 5 is connected with live wire L binding post 11 by a fuse holder 15, live wire L is connected on the next contact binding post 5, and between fire, zero line L,

N binding post

11 and 12, be connected with a fuse holder according to the order of sequence, pipe 16 and one resistance 15 indicator lights 6.

The description of comprehensive the foregoing description as can be seen, in the utility model, is connected with resistance 14, indicator light 6 between fire, zero line L, N two pin terminals according to the order of sequence.Be connected to fuse holder and fuse 15 and 16 at live wire

L binding post

11 and 5 of the next contact binding posts.In addition, the pin 8 that is fixed on the housing seat 7 has two, three or four.
