Description

Simple and easy switch jump structure

The utility model belongs to the electric equipment products field, refer in particular to a kind of simple and easy switch jump structure, interlock one alloy piece is done reciprocating action up or down by pressing button may command one link driving element, make circuit loop form outage or conducting, when current overload, this alloy piece produces strain when overheated, and upwards strain and escape, form circuit loop and cut off the power supply, safeguard Electrical Safety.

General mains switch only has out and closes two kinds of actuating lengths; manually control by the people fully; but in the unstable area of power supply; the time have the situation of overload to take place; the people can't find this phenomenon and continue and use this moment, will cause overload overheated, caused electric wire to cock off even the public danger of fire; form the use potential collision hazard of switch, therefore the further improvement of switch is just arranged.

Switch after the improvement, inside is provided with one by the two or more metal alloys that metal material constituted, phenomenon by its overheated generation distortion, cut off the electricity supply and when current overload, automatically spring open, case is too numerous to enumerate before the patent of relevant this kind construction of switch, as No. the 5786742nd, United States Patent (USP), No. 5223813, No. 4937548, No. 4661667, No. 4931762, No. 5451729, No. 4704594 etc. too numerous to enumerate, aforementioned each preceding case etc., or can be at current overload and automatically spring open to cut off circuit loop when overheated, right but complex structure, be difficult for making, be its shortcoming, and the separating reaction of circuit loop contact is slow, can't immediate response, the electric current of overload still can flow into electrical equipment by contact in a flash, still has the situation that causes the electrical equipment damage.

In addition, construction of switch as routine is No. the 5933069th, United States Patent (USP), shown in Figure 1A, B, C, though it is relatively more following with aforementioned all cases, oneself signs an undertaking, and structure is simple, assembling is easy, can solve the advantage of the overheated electricity consumption danger of current overload, but it provides the machine mechanism of deciding of location to include: one is linked to the contiguous block c of the locating piece a of button, the compression spring b that elastic thrust is provided and connection compression spring b and body combination, and this detent mechanism assembling still has the space of simplification; Its shortcoming is: the locating piece a of (1) detent mechanism, compression spring b, contiguous block c are assembled in body and are difficult for; (2) locating piece a is compressed spring b elastic force ejection body wall, produce direct frictional force, when alloy piece e uses because of long-time that to cause metallic elastic tired, in the time of can't effectively being bent downwardly according to original design, upper contact h will closely be contacted with following contact i, the bad shortcoming of current circuit when causing power on circuitry, even produce the danger that spark causes circuit to cock off.

No. the 5828284th, United States Patent (USP), it and aforesaid conventional case one are same applicant's invention, and its interlock principle with one action of conventional case is identical, and modular construction only has the fine difference of locating piece a, moving part f and hook portion g, and its shortcoming is still identical with conventional case one.

Conventional case two is No. the 5262748th, United States Patent (USP), shown in Fig. 2 A, B, it had before been created for this case inventor, it compares with aforementioned all cases and conventional case one, tool has the advantage that modular construction is simple, assembling is easy, cost is low, yet the n shape flexure strip of escape location directly contacts with alloy piece in its structure, this n shape flexure strip conducts from the heat of alloy piece for a long time and is urged for a long time, to the elastic-restoring force of n shape flexure strip be reduced, can't guarantee escape and location that current overload is overheated, remain to be improved again.

Conventional case three is No. the 5760672nd, United States Patent (USP), shown in Fig. 3 A, B, C, it and aforementioned all cases are relatively, possess the advantage that modular construction is simple, assembling is easy, cost is low is arranged, yet the safety device that lacks the escape location in its structure, can't solve the overheated electricity consumption danger of current overload, so case is still desirable not to the utmost and remain further to be improved again before these all routines.

The purpose of this utility model is to propose a kind of simple and easy switch jump structure of being made up of alloy piece, link driving element and setting element, when current overload, this alloy piece produces strain when overheated, and upwards strain and escape, form circuit loop and cut off the power supply and cut off the power supply, guarantee Electrical Safety; In addition, it is simple in structure, assembling is easy, interlock is rapid, reaches cost of manufacture economy, and the current overload escape is swift in response, thereby has solved the existing in prior technology problem.

The technical scheme that the utility model adopted is: it is to establish a button in a switch box body group, connect a link driving element, an alloy piece, organize separately and establish a setting element, when current overload, owing to making down circuitry and this link driving element of interlock, this alloy piece strain make button reply former user mode, simultaneously alloy piece is positioned the circuit breaker position, it is characterized in that with this setting element:

This alloy piece, the one end is provided with first contact, and the other end is connected in first contact terminal;

This link driving element, the one end is provided with connecting rod, cooperates in the connecting hole that is placed through button below lug, and the other end of link driving element is formed with the clamping recess, this this alloy piece of clamping recess clamping;

This setting element, it is formed with a lug boss, and an end is fixed in the switch box body.

Advantage of the present utility model is:

When current overload, this alloy piece produces strain when overheated, and upwards strain and escape, forms circuit loop and opens circuit and cut off the power supply, and guarantees the guarantee of Electrical Safety.

In addition, simple in structure, assembling easily, interlock is rapid, reaches cost of manufacture economy, the willing purpose of current overload escape.
