Abstract

The utility model relates to a switch, which is based on the current end cap (1), the base body (2), the wiring terminal (5) and the push-button (9), wherein the base body (2) is provided with two bottle-shaped wiring socket (6) and is in the electric connection with the wiring terminal (5); the push-button (9) is provided with a U-bar connected double-plug (8) and a locking location spring (3). The mode of double-point synchronous plug-in switch on/off current better solves the problem of poor switch connection, prone fire striking and arc generating, and has the advantages of simple structure, long service life, convenient use, safe and reliable performance, etc. Thereby the switch is widely used in the circuit of large power and large current in need of the switch.

Description

Switch

The utility model relates to a kind of switch, relates in particular to a kind of switch that uses than high-power electric appliance.

At present, known switch structure is mainly by single point contacts formula switch (as switch on wall), multiple spot contact switch (as switch on the A.C. contactor) and single-point plug-in type switch (as knife switch).Because switch adopts contact contacting type electric current of make-and-break construction of switch form, has problems such as loose contact, arcing harm, shorten switch useful life, limit switch is by more high-power electric current.

The purpose of this utility model provides a kind of switch, and it not only contacts, arcing is little, and the reliability height, and the life-span is long, and is easy to install.

The purpose of this utility model is achieved in that a kind of switch, and end cap (1), pedestal (2), binding post (5), button (9) are arranged, and end cap (1) covers on pedestal (2).Trapezoid boss (7) is set in pedestal (2), fixes two bottleneck connector sockets (6) on the boss (7), connector socket (6) is electrically connected with binding post (5) respectively.Pedestal (2) is gone up by button fixed axis (10) and is connected bowl-type button (9), and button (9) center is provided with a strip hole (12).Two opening annulus at locking positioning spring (3) two ends, an end hook are on strip hole (12), and the other end is hooked in the hole on the stator (4) that is fixed on the pedestal (2).One boss (11) also is set in button (9), and boss (11) is gone up fixedly channel steel shape disjunctor double plug (8).Press button (9) one ends, disjunctor double plug (8) two point will be inserted in the bottleneck connector socket (6) synchronously, switch is in closure state, and locking positioning spring this moment (3) slides into button and is pressed into the end locking press button.Otherwise, to press the button other end and put in place, the switch locking is in off-state.

The design principle of switch is: adopt the two point electric current of make-and-break mode of pegging graft synchronously can guarantee that switch has the long-pending and minimum contact resistance of enough conductive contact surfaces, and minimum switch over travel.Improved breaker acting speed.Shortened the arc time.Overcome the loose contact phenomenon, thereby be implemented in the target that realizes increasing substantially power under the less volume of switch.

Owing to adopt such scheme, switch module adopts the synchronous plug-in type electric current of make-and-break of two point form, has that contact is good, arcing is little, reliability is high, easy to install, advantage of simple structure, greatly improves the useful life and the suitable power of switch.

Below in conjunction with drawings and Examples the utility model is described further.

Fig. 1 is that the utility model is analysed and observe organigram.

Fig. 2 is the A-A cutaway view of Fig. 1.

Among the figure: 1, end cap 2, pedestal 3, locking positioning spring 4, stator 5, binding post 6, connector socket 7, boss 8, plug 9, button 10, button fixed axis 11, boss 12, strip hole

Fig. 1, embodiment illustrated in fig. 2 in, a kind of switch has end cap (1), pedestal (2), binding post (5), button (9), end cap (1) covers on pedestal (2).Trapezoid boss (7) is set in insulating base frame (2), and boss (7) is gone up screw thread and is fixed two bottleneck copper connector sockets (6), and connector socket (6) is electrically connected with binding post (5) respectively.Pedestal (2) is gone up by button fixed axis (10) and is connect bowl-type button (9), and button (9) center is provided with a strip hole (12).Two opening annulus at locking positioning spring (3) two ends, an end hook are on strip hole (12), in the hole on the stator (4) of an end hook on being fixed on pedestal (2).An end also is provided with a boss (11) in button (9), and boss (11) is gone up fixing copper channel steel shape disjunctor double plug (8), and the plug cross section is preferably wedge shape.

Claims (2)

1, a kind of switch, end cap (1), pedestal (2), binding post (5), button (9) are arranged, end cap (1) covers on pedestal (2), it is characterized in that: trapezoid boss (7) is set in pedestal (2), fix two bottleneck connector sockets (6) on the boss (7), connector socket (6) is electrically connected with binding post (5) respectively; Pedestal (2) is gone up by button fixed axis (10) and is connected bowl-type button (9), the button center is provided with a strip hole (12), two opening annulus at locking positioning spring (3) two ends, an end hook are on strip hole (12), and the other end is hooked in the hole on the stator (4) that is fixed on the pedestal (2); An end also is provided with a boss in button (9), and (11), boss (11) is gone up fixedly channel steel shape disjunctor double plug (8).

2, switch according to claim 1, its feature: its plug cross section of channel steel shape disjunctor double plug (8) is a wedge shape.
