Abstract
The utility model discloses a thread-free wiring terminal. The thread-free wiring terminal comprises two coterminous arms, and wherein, one arm is provided with an aperture, and the other arm whose one side is through the aperture is positioned in the aperture. The thread-free wiring terminal adopts stainless steel material and is processed by a special technology to make the thread-free wiring terminal to be with durable elasticity and anti-corrosiveness. When installing a conductor, user depresses the one arm of the thread-free wiring terminal with a screwdriver and inserts the conductor into the aperture of the arm, and then user looses the screwdriver, the conductor can be automatically clamped on the thread-free wiring terminal, and thereby, user can finish conveniently and rapidly the installation of the conductor. Besides, the clamp force acted on the conductor by the thread-free wiring terminal is provided with the own elastic structure of the thread-free wiring terminal and can not be changed with different people or different installation occasions, so the case that the clamp force is too large for the conductor to be fractured, and alternatively, the clamp force is too small for the conductor to be loosed can not occur.
Description
Technical field
The utility model relates to a kind of no screw terminal, relates to a kind of no screw terminal that is used on switch or the socket specifically.
Background technology
At present, people are in being installed in lead the use device procedures, such as switch and socket, generally the mode that compresses lead by bolt and stator is installed, this structure is all cumbersome in installation and removal lead process, particularly in the place of the frequent dismounting of needs, seems particularly outstanding.In addition, in installation process, because of often lead being applied excessive thrust, the as easy as rolling off a log phenomenon that wire fracture occurs.And be used for the no thread terminal of switch, socket, all can not be used for fastening multicore cable.
Summary of the invention
The purpose of this utility model provides a kind of quick, attachment security easy to loading and unloading does not have screw terminal reliably.
The utility model is achieved through the following technical solutions.
A kind of no screw terminal is characterized in that: described no screw terminal comprises two continuous arms, and wherein an arm has a hole, and an end of another arm passes this hole and is positioned at the hole.
The hole of opening on the described arm is a square opening
Described two arms link to each other by the 3rd limit, and connecting place is provided with fillet.
All have the hole on the 3rd limit between described another arm and two arms.
The Kong Chengyi end of opening on the 3rd limit between described another arm and two arms narrows fan-shaped or the triangle or the heart shape of another disconnected expansion.
The narrow end in the hole of opening on the 3rd limit between described another arm and two arms is near the link on the 3rd limit between described another arm and two arms.
The utility model compared with prior art has the following advantages.
No screw terminal described in the utility model comprises two continuous arms, and wherein an arm has a hole, and an end of another arm passes this hole and is positioned at the hole.This no screw terminal adopts stainless steel material and makes it have lasting elastic force and rustless property through special PROCESS FOR TREATMENT.When lead is installed, to not have an arm of screw terminal with screwdriver and depress, insert in the aperture of lead from this arm, unclamps screwdriver then, no screw terminal will be automatically with the lead banding on terminal, thereby can finish conductor mounting quickly and easily.In addition, no screw terminal provides the clamping force of the lead elastic construction by no screw terminal itself, can or different occasion is not installed and not change, therefore, thrust can not occur and cross that senior general's lead pressure break or thrust are too small to cause loosening situation along with different people.
The hole of opening on the 3rd limit between described another arm and two arms is tending towards evenly the distortion of terminal, reduces stress and concentrates, and makes the elasticity of binding post better, more reliable performance.
Description of drawings
Fig. 1 is installed in assembly structure schematic diagram on the no screw terminal for lead in the utility model;
Fig. 2 does not have the longitudinal sectional view of screw terminal for the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
As Fig. 1 and shown in Figure 2, no screw terminal comprises two arms 11,12, two arms 11,12 link to each other by one the 3rd limit 13, be equipped with fillet at two arms 11,12 and the 3rd limit 13 connecting places, wherein have a square opening a on the arm 11, one end of another arm 12 passes this hole a and is positioned at hole a, and whole no screw terminal is seen from the side and is triangular shape.When lead is installed, at first an arm 11 that will not have a screw terminal with screwdriver is depressed, one end of one water conservancy diversion copper sheet 2 is inserted in the hole a on the arm 11 and with copper sheet 2 to be close on the arm 11, then with in the lead 3 patchhole a, make lead 3 and water conservancy diversion copper sheet 2 close proximity, become less severe behind the screwdriver, no screw terminal relies on the elastic force of self that lead 3 is clamped in the hole a between water conservancy diversion copper sheet 2 and the no screw terminal.For increasing the pulling force between lead and the water conservancy diversion copper sheet 2, make a folding shape on the position water conservancy diversion copper sheet 2 and contacting of lead 3 and tighten up the position.No screw terminal adopts stainless steel material and makes it have lasting elastic force and rustless property through special PROCESS FOR TREATMENT, for reducing the difficulty of PROCESS FOR TREATMENT, on the 3rd limit 13 between an other arm 12 and two arms, have scallop hole b, like this, can make described another arm and the distortion of the 3rd limit between two arms of no screw terminal more even, elasticity is better, more reliable performance.
No screw terminal two arms 11,12 can also link to each other by the limit of other shape, such as adopting arc, undaform or L shaped except can linking to each other by a straight flange in the utility model.In a word, no matter adopt the limit of what shape to link to each other all in the protection range of this patent.
