Abstract

The utility model discloses a rocker switch which comprises a casing, a dynamic contact piece, a static contact piece, a button, a lock piece, a spring and an indicator. The rocker switch is characterized in that the lock piece is shaped like a trapezium with a smaller upper part and a larger lower part; a cambered surface is formed at the top of the lock piece; a blind hole or a lug boss is formed at the bottom of the lock piece; lock hooks are formed on two sides in the middle of the lock piece; the lock piece is arranged in a locking cavity of the casing and hooked on one surface of the locking cavity; the upper part of an inclined plane clings to the wall of locking cavity, the lower part of the inclined plane leans to the door of the locking cavity, the button is arranged on the inclined plane, and the spring is arranged below the inclined plane; the lower end of the spring is sleeved on a lug boss in the middle of the dynamic contact piece; the dynamic contact piece is arranged on a terminal lug; and silver points are formed at two ends of the dynamic contact piece, which are in contact with or separated from silver points on the static contact piece.

Description

A kind of improvement type ship type switch

Technical field

The utility model relates to the appliance switch technical field, is a kind of improvement type ship type switch.

Background technology

Electronic technology is in develop rapidly, and increasing product has all been used electron controls technology, and these some electronic apparatus devices also need to finish its mission by interactive mode.Briefly at present also need to finish concrete operation by push-button switches different on the pressing device.The nothing lock push-button switch that these some push-button switch overwhelming majority are small voltage weak currents is characterized in that stroke is very little, and what have is even zero, and it is consistent opening with the position of closing, most typical switch such as soft-touch control.Along with the development of electron controls technology, this class switch is more and more.But at present electric equipment products also be unable to do without the class of heavy current self-locking always switch, self-locking class and do not have the obvious difference that lock class push-button switch has three aspects, and 1. function aspects, a heavy current normally, another one is weak current normally., 2. total stroke aspect, a stroke is very little or zero, the bigger 2.5-5 millimeter of another one.3. the change in location aspect does not have above the fold to change before and after the operation, and another one has visibility point to change.

On same product, exist two dissimilar switches, therefore always wish that at technological layer they accessing unified aspect the outward appearance or coordinating, therefore produce from resetting the locking press button switch.This class switch just obtained application before more than ten years, just used the self-locking type mains switch that resets certainly on colour TV.Along with high speed development of national economy, the raising constantly of living standards of the people, constantly the weeding out the old and bring forth the new of electric equipment products, so market demand more more novel and its coupling switches.But the self-locking class switch great majority of Shi Yonging are ship type switches in the market, and its kind and style seldom are difficult to satisfy the demand in market.

Summary of the invention

The purpose of this utility model is in order to provide style novel a kind of ship type switch from the self-locking type that resets various in style to market, and its characteristics stroke is little, comfortable feel, belt switch that load is big.Satisfy people to the pursuit of fashionable life with to pursuit safe in utilization.

Design of the present utility model is to design according to existing ship type switch and a kind of patented technology patent No. 200920072225.2 that resets self-lock switch certainly, and it is made of shell, movable contact piece, stationary contact spare, button, latch fitting, spring and indicating device; It is characterized in that described latch fitting is up-small and down-big like trapezoidal, the lock top is a cambered surface, and lock bottom has blind hole, and boss is perhaps arranged, and middle two sides have latch hook; Latch fitting places in the lock chamber of housing, and hook is in lock chamber one end face, and lock chamber wall is pasted on top, inclined-plane, and the bottom is by lock chamber door, on button is arranged, under spring is arranged; The spring lower end is placed in the middle of the movable contact piece on the boss, and movable contact piece places on the lug plate, and its two end has silver point, with the silver point contact of stationary contact spare or separate.Place in the lock bottom blind hole on the spring or boss on.

The design is simple in structure, dependable performance, and stroke is little, open state and off status position consistency, comfortable feel, bearing capacity are big, and this spline structure can provide bigger space for appearance design.

Description of drawings

Below in conjunction with accompanying drawing and example, the utility model is further specified.

Fig. 1 is a kind of improvement type ship type construction of switch schematic diagram.

Among the figure, left shell (1), right shell body (2), button (3), latch fitting (4), stationary contact spare (5), lug plate (6), movable contact piece (7), spring (8), indicating device (9), stationary contact spare (10), lock resonator end surface (1-1), lock chamber door (1-2), lock chamber (1-3), indicating window (3-1), blind hole (4-1), latch hook (4-2), lock top (4-3), silver point (5-1), silver point (7-1), boss (7-2).

Embodiment

A kind of type ship type switch that improves is to improve design according to the Patent technology characteristic of existing ship type switch and plane push-button switch, its housing is synthetic by left shell (1) and right shell body (2), has button (3), latch fitting (4), stationary contact spare (5), lug plate (6), movable contact piece (7), spring (8), indicating device (9) and stationary contact spare (10) to constitute in the housing.

Technical characterictic of the present utility model is that the latch fitting of switch is up-small and down-big like trapezoidal, and its lock top (4-3) is a cambered surface, and middle two sides have latch hook (4-2), and a lock blind hole or boss (7-2) are arranged at the lock bottom, place in the lock chamber (1-3) of panel.Its latch hook hook is in lock resonator end surface (1-1), its top, inclined-plane is affixed on lock chamber wall, the bottom is against lock chamber door (1-2), it is a button above top, place on spring or its boss in its blind hole and be with spring, the spring lower end is enclosed within on the boss (7-2) of movable contact piece, and movable contact piece is placed on the lug plate (6), the silver point (5-1) of silver point of movable contact piece (7-1) and stationary contact spare (5) or the silver point (5-1) of stationary contact spare (10) contact and separate, and finish the action of Push And Release.

Another kind is the switch of indicating device, and its stationary contact spare (10) is the lug plate (6) of indicating device, and the lead-in wire of indicating device (9) links to each other with stationary contact spare (10) with lug plate (6) respectively.Button is 5 light buttons or the button that indicating window (3-1) is housed.
