Abstract

The utility model relates to the improvement of the connecting means of the existing electrical accessories. The utility model is a plug-in connecting means, comprising a V-shaped spring lamination, a clamping wire spring with the clamping wire part of a sharp edge angle, and a wire connecting terminal. When connecting, only one conducting wire whose front end is peeled is inserted in the connecting means. The utility model has the advantages of convenient operation, saving time, easy fabrication and high safety.

Description

Plug-in connecting means for electrical accessories

The utility model belongs to a kind of electric accessories, particularly a kind of plug in type connection device easy for installation.

At present aspect the wiring of electric accessories, generally adopt screw line ball formula binding post, especially with the most use in the great indoor electric appliance annex of quantity (as switch, insurance, connector assembly etc.), following two kinds of modes are generally arranged: the one, wire termination is curved annular or burn-on ring plate usefulness screw in compression on the binding post of electrical equipment, promptly annular line ball formula; The 2nd, lead inserted in the binding post line hole with screw in compression connect the line ball formula of promptly inserting.This traditional termination loading and unloading are inconvenient, when taking a lot of work; And the processing of screw screw is complicated when making, cost is higher; It is unreliable to connect at secure context, if screw twist pine, then easily cause loose contact, if overtorquing, easy damaged lead has then been used of a specified duration easily to come off even is disconnected and produce the loss of power accident.

Task of the present utility model is to want the reform traditional mode of connection, and a kind of easy to loading and unloading, easy to manufacture, safe and reliable termination is provided.

The utility model is achieved in that at the electrical equipment body and installs on the position of termination, load onto cliping line spring and fixing with the stator (or plate) of binding post, perhaps in concealed installation electrical equipment, seal fixing with cover plate, lead connects employing and inserts the mode of connection, being about to lead inserts between binding post and the line ball parts, the main points of this device are that the line ball parts are cliping line spring, utilize the pressure of spring leaf that lead is tightly pushed down, make it good to keep in touch, even and block lead and make it when not dialling Spring Card, firmly can not deviate near the lug plate of living binding post.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is that the utility model is used in the structure enlarged diagram in the concealed installation electric accessories.

Fig. 3 is that the utility model is used in the installation embodiment schematic diagram on two pole sockets.

Fig. 4 is that the utility model is used in the installation embodiment schematic diagram on the pulling switch.

Below in conjunction with accompanying drawing the utility model is further described: 1 is the lug plate of binding post among Fig. 1, the 2nd, and the stator of binding post (or plate), binding post are the parts of direct wiring, also the part of electrical function element; The 3rd, cliping line spring, it is with the shell fragment that has certain flexible band to make, and two parts are arranged; Compacted conductor partly is " V " shape shell fragment, the thread jamming part branch is the shell fragment that has sharp corners, two shell fragments compress lead and make it to keep in touch after insertion well and can not withdraw from, as extracting lead, as long as insert between cliping line spring and the lead contact-making surface with screwdriver, the card line shell fragment of cliping line spring is separated with lead, can extract lead; The 4th, electrical equipment body, the 5th, the single condctor of end peeling.

Fig. 2 is the push-button switch embodiment part schematic diagram that this device is used in concealed installation, and in the electrical equipment of concealed installation, termination all is encapsulated in the electric accessories, connect or do not allow to open when taking out stitches cover plate, so adopt structure shown in Figure 2,1a is the electrical equipment cover plate among the figure, it is used to withstand and fixed card wire spring 2a; The installation direction of cliping line spring is with shown in Figure 1 opposite, its card line shell fragment and lead direction of insertion forward, it with Fig. 1 in card line shell fragment shape slightly different, but act on, thereby also can be used in the bright dress electric accessories; 3a is a binding post, the sheet (or plate) that it does not have the fixed card wire spring to use; 4a is the electrical equipment body, and 5a is a lead, and 6a presses the pressing spring device of card line shell fragment with hole or installation, as long as one push spring or insert a thing and back down card line shell fragment inward from press the shell fragment hole, can extract lead easily.

1b is the sleeve of band binding post among Fig. 3, and 2b is a cliping line spring, and 3b is a lead.1c is a binding post among Fig. 4, and 2c is a cliping line spring, and 3c is a lead.

Maximum characteristics of the present utility model are to have changed the mode of connection, adopt plug in type connection, make it very convenient, as long as insert from the line hole; Slightly long such as lead, then can be from the upper end lead be pulled out and cut off redundance, like this, a large amount of electrical equipment of installing in new building construction Part just can be saved the plenty of time, shortens the completion time of project, obtains good effect. This device uses reliable, can guarantee lead and binding post good contact, is difficult for deviating from when pulling at lead under normal conditions. In addition, because it imbeds in the electrical equipment body no exposed part, thereby use safety; Simultaneously, its cliping line spring can be produced in a large number with known Sheet Metal Forming Technology, so characteristics easy to manufacture are arranged again.

Claims

1, a kind of termination of electric accessories, form by binding post (1), line ball parts, electrical equipment body (4), feature of the present utility model is: said termination adopts and inserts the mode of connection, its line ball parts are cliping line spring (3), and it divides formation by " V " shape line ball part and the thread jamming part that has sharp corners; Binding post has the wiring part of contact wire, perhaps also has the standing part of fixed card wire spring.

2, according to the termination of claim 1, it is characterized in that: " V " shape line ball part and thread jamming part divide all with there being certain flexible band to make shell fragment, stator (2) with binding post during installation is fixed on the electrical equipment body, or is encapsulated in the body of concealed installation electrical equipment.

3,, it is characterized in that on the close position of shell fragment (2a) of electrical equipment body, a pressing spring hole being arranged or a pressing spring device (6a) being installed according to the termination of claim 2.
