Abstract

The utility model relates to a power source plug which comprises a cover, a base, a plug and a terminal. The utility model is characterized in that the plug is an aequilate strip-shaped piece, the terminal positioned on the plug is a cube aequilate with the plug, and the base is provided with a jack matching with the shape and size of the cross-section of the terminal inside. The utility model solves the problems of existing power plugs, such as poor connecting and inserting stability and reliability, high manufacturing cost, etc.

Description

Attaching plug

The utility model is a kind of attaching plug.

Existing attaching plug can see that wherein Fig. 1 is that front view, Fig. 4 are the A-A cutaway views among Fig. 1 from Fig. 1 and Fig. 4.It include cover 1, pedestal 2, latch 3, binding post 4, attachment screw 5, tension disc 6, trip bolt 7, wherein latch also can be seen from Fig. 5 with the structure of binding post, and (c) figure is that both front view, (d) figure when connecting one are the B-B cutaway views among (c) figure among Fig. 5.See that from figure latch is a T font thin slice wide at the top and narrow at the bottom, binding post is the annulus cylindricality, and both fuse with riveted, and the periphery diameter of binding post is less than the upper width of latch.The shortcoming of this attaching plug is: 1) the installing and locating face of latch in the pedestal jack is two sidewalls on its top, this two side is thin and the jack height is limited because of wall, so this location can not overcome the rolling power of latch in the plug process effectively, therefore latch is loosening easily, thereby has influence on the stability and the reliability of the work of patching; 2) binding post, technology comparatively complicated trouble and riveted had relatively high expectations with the riveted construction of latch, so manufacturing cost also improves.

The purpose of this utility model is to overcome the shortcoming that exists in the above-mentioned prior art, a kind of simple in structure, low cost of manufacture is provided and patches working stability, safe and reliable attaching plug.

The utility model attaching plug includes lid, pedestal, latch, binding post, its feature is: latch is wide strip piece, the binding post that is positioned at its top is the cube wide with latch, has and the shape of cross section of binding post, the jack that size is complementary in the pedestal simultaneously.Binding post can be a square, also can be cuboid, and it and latch are disjunctor shape.

To and contrast accompanying drawing by embodiment below, the utility model attaching plug will be further described below.Have in the accompanying drawing:

Fig. 1 is the front view of the utility model attaching plug;

Fig. 2 is the A-A cutaway view among Fig. 1;

Fig. 3 be binding post in the utility model attaching plug with the structure chart of latch, wherein (a) is that their front view, (b) are the C-C cutaway views in (a);

Fig. 4 is that the existing power supply plug removes to cover later vertical view, because of the front view of existing power supply plug is identical with Fig. 1 in the utility model, so Fig. 4 also can be the A-A cutaway view among Fig. 1;

Fig. 5 is that binding post in the existing power supply plug is with the structure chart of latch.

See from Fig. 1 and Fig. 2, the utility model attaching plug include cover 1, pedestal 2, both link into an integrated entity with screw 5.Latch 3 and binding post 4 can see from Fig. 3 that also the former is wide strip piece, and promptly upper and lower width is identical, and the latter is one and has cuboid or the square that holds out against screw 7, and binding post and latch is wide, both disjunctors.Have three jacks in the pedestal 2, and the cross section of each jack is complementary with the cross section of binding post all.Pedestal also has a tension disc 6 on the electric wire port of export, be used to push down power line, and it is stabilized on the attaching plug.

The utility model attaching plug is when using installation, in the jack in first latch, the binding post insertion pedestal with disjunctor, again three heart yearns of mains terminals are penetrated respectively in the circular hole on the binding post and fastening to hold out against screw 7, pass in the endoporus on other end pedestal right side from Fig. 2 of power line, and it is it is firm with tension disc 6, then lid 1 is closed with pedestal, again with screw 5 fastening getting final product.

The utility model has the advantages that: 1) binding post with it square or rectangular three sides Wall P, Q, M and pedestal Socket walls are fitted and are located, and latch and binding post disjunctor, because of This attaching plug in use its latch is difficult for rocking, and patches working stability, reliable thereby make; 2) binding post makes with the conjoined structure of latch that the plug processing capacity reduces, cost.

Claims
