Description

Push-button switch of locking type

The present invention relates to a locking type push button switch, and more particularly, to an improved configuration of a push button switch widely used in automotive electronic systems.

The push button switch is a repetitive push operation, and the ON-OFF configuration is repeatedly used, and thus it is widely used in emergency lamps, switch for air conditioner operation, and various industrial devices of the instrument panel of automobiles.

Conventionally, various types of push button switches are conceived, and most configurations include moving blocks which are guided in the housing and slide-operated, and contact pieces fixed to the moving blocks are contacted or separated from the terminal plate attached to the housing. Thereby conducting electrical conduction.

In addition, the locking means is performed as a lock groove such as a heart shape in which a locking pin and a locking pin are inserted and locked between the housing and the moving block.

In this operation, since the locking pin is very small in size and must be operated while pressing against the locking groove, a pressing means for pressing against the locking groove is required. In the conventional configuration, the pressing pin is provided by mounting a leaf spring on the locking pin. .

The above-described configuration is disclosed in US Patent No. 4,383,153 of Fig. 1 whose patent rights have expired, and Korean Patent Publication No. 2002-0088028 of Fig. 2, which is patented using most of this US patent.

In the configuration of FIG. 1, the support member 109 is machined as a metal plate as a means for pressing the acting pin 108 moving along the cam groove (not shown) formed in the moving block 101 to the cam groove side of the moving block 101. Tongue 109C acts to press it.

2 also discloses a configuration in which the plate spring 200 having the same shape as that of FIG. 1 presses the locking pin 201 against the moving groove 202.

The conventional construction described above requires assembling a pin member, which is an extremely small member, in a housing, and assembling a tongue or plate spring, which is also an extremely small member, on top of it, which is very difficult and requires considerable attention of the operator.

This is also a major factor in the difficulty of automated assembly lines, and economics is also a major factor in manufacturing costs.

In addition, since a plurality of members, such as pins and springs, are assembled, failures caused by repetitive operation also occur frequently, thereby deteriorating reliability.

The locking type push button switch of the present invention was devised in consideration of the problems of the conventional source configuration, and provided by changing the locking means and the terminal configuration, which is very easy to assemble and improves the reliability of operation, but also provides an economical push button switch. It aims to provide.

Incidentally, another object is to enable manufacturing of an automated assembly line by eliminating components that require the attention of assembly while minimizing the number of parts and manufacturing them at low cost.

Hereinafter, with reference to the accompanying drawings will be described a preferred configuration and operation of the present invention for achieving the above object.

The locking type push button switch 1 to which the technology of the present invention is applied is a case 4 having a terminal 2 and a terminal 3 and a moving block 5 slidably coupled to the case 4. It is composed.

In the connecting position of the case 4 and the moving block 5 (the bottom surface of the case and the bottom of the moving block in the drawing), the locking and unlocking states can be selected to select ON / OFF of the switch. It further comprises a locking means (6).

The case 4 has a box-type case body 11 having a moving hole 10 so that the upper and rear ends thereof and the moving block 5 can be inserted therein, and both sides of the case body 11. The wall 12 is configured by inserting the terminal 3 having the terminal pin 13 protruded inwardly together with the case body 11.

The upper surface of the front wall 15 of the case body 11 is provided with a terminal intermittent opening 17 having an intermittent hole 16 at the center thereof so that the pin holes 18 may be coupled to both sides of the case body 11 so as to be coupled to the terminal pins 13. It is formed to be able to be coupled to the fixing pin 19 is formed to protrude in front of the terminal (2) built in the circuit means.

The moving block 5 includes a block body 22 formed by protruding the guides 20 and 21 near the corners of the moving hole 10 formed in the case 4 to allow easy sliding without play. .

Retracts the block body 22 at all times by interposing a spring 25 between the spring groove 23 formed at the front center of the block body 22 and the front wall inner surface 24 of the case body 11. To be in.

In the intermediate position of the block body 22 is provided with a switch 26 to enable switching through contact and separation with the terminal pin 13, the switch 26 has a horizontal plane 27 and a vertical plane 28 The switch body 29 is bent so as to have a plate-like member roughly in a ∩ shape.

The switch body 29 constitutes the switch body 29 in the switch settling groove 30 formed on the upper surface of the block body 22 and the switch control opening 31 formed on both sides of the block body 22, respectively. Both ends of the horizontal plane 27 and the vertical plane 28 are positioned to maintain a stable state.

The front and rear of the moving block 5 by protruding the switch pin 32 so as to have elasticity before and after the intermediate position (same position as the terminal pin) of the vertical surface 28 constituting the switch body 29. By the terminal pin 13 and the contact and configured to be separated.

The locking means 6 is in an ON state when the moving block 5 is pressed once on the bottom surface 40 of the moving block 5 and the bottom surface 41 of the case 4, and when it is pressed again, the locking means 6 is turned off. It is equipped to be able to switch to (OFF) state

A feature of the locking means 6 to which the technique of the present invention is applied is to form a locking pin 42 having a certain elasticity on the bottom surface 40 of the moving block 5, and the bottom surface 41 of the case 4. The locking groove 43 is formed to be concave in, so that the locking pin 42 moves along the locking groove 43 to enable locking and unlocking.

The locking pin 42 forms a pin body 45 to an intermediate position so as to protrude downwardly integrally with the moving block 5 from the front side of the bottom of the moving block 5 to the rear side, and behind the pin body 45. The extension portion 46 is formed to be biased in one direction while reducing the width.

An end of the extension portion 46 protrudes more than a pin body 45 to protrude a pin head 48 having a locking jaw 47, and the front and rear sides of the pin head 48 are inclined portions 49. Form to form.

The locking groove 43 forms a stop surface 50 in the width direction so as to stop the locking pin 42 retracted by the spring 25 at the rear side of the bottom surface 40 of the case 4, The front of the stop surface 50 forms the operating surface 51 at intervals such that the terminal pin 13 and the switch pin 32 can contact.

An inclined surface 52 is formed between the stop surface 50 and the operating surface 51 to easily guide the pin head 48 of the locking pin 42, and the operating surface 51 is guided locking. The pin 42 is formed to be concaved in the direction of the stop surface 50 so as to have the same shape as the pin head 48 so that the pin 42 can be interrupted.

Naturally, the inclined portion 52 formed on the inclined surface 52 and the pin head 48 has the same inclined angle so that the operation can be easily performed.

In front of the operating surface 51 is further spaced apart space 55 for separating the pin head 48 from the operating surface 51 and the separation space 56 extending from the spaced surface 55 further. Form.

The starting point SP of the separation surface 55 is located inward of the front end surface EP of the pin head 48, and the separation space 56 has the pin head 48 sufficiently operating surface 51. It is desirable to have a length (L) enough to escape.

Of course, the opposite side of the locking groove 43 in which the stop surface 50 and the operating surface 51, the inclined surface 52, the separation surface 55, and the separation space 56 are formed is the pin head 48. It would be natural to have a straight line in order to avoid returning to (50).

The present invention as described above,

Push the moving block 5 coupled with the switch 26 to the moving hole 10 formed in the case 4, and by coupling the terminal 2 to the terminal 3 inserted into the case 4 The button switch 1 is completed.

Looking at the initial state assembled as described above, the moving block 5 to be inserted into the moving hole 10 of the case 4 is free from play by the guides (20, 21) formed in the corner portion of the block body 22 Maintaining a stable state, the locking pin 42 is coupled to the locking groove 43 formed integrally with the bottom surface 41 of the case 4 and the bottom of the moving block 5.

That is, the pin head 48 constituting the locking pin 42 is positioned on the stop face 50 constituting the locking groove 43 so that the switch is turned off. In this state, the moving block 5 The force to retreat the moving block 5 is always generated by the spring 25 interposed between the spring groove 23 formed on the front side of the case and the front wall inner surface 24 of the case 4.

When the pin head 48 is located on the stop surface 50 as described above, since the moving block 5 is in the retracted state, the switch pin 32 provided in the switch 26 mounted on the moving block 5 is It protrudes inwardly of the terminal 3 inserted into the case 30 and is not in contact with the exposed terminal pin 13.

In this state, when the moving block 5 is pushed forward in the direction of the case 4, the spring 25 interposed between the moving block 5 and the case 4 is contracted and the pin head constituting the locking pin 42. 48 is in contact with the inclined surface 52 while leaving the stop surface (50).

At this time, since the inclined surface 52 has the same inclination as the inclined portion 49 formed in the pin head 48, initial connection is easily performed, and continuous operation is possible.

When the continuous force is applied to the moving block 5 in the above state, the pin head 48 extends to the front of the pin body 45 constituting the locking pin 42 and has an elasticity to some extent. Since the fin head 48 is deformed along the inclined surface 52 while the inclined surface 52 is moved, the fin head 48 is formed.

As described above, the pin head 48 is deformed in the outward direction of the inclined surface 52 until it escapes the inclined surface 52, and the elasticity enters the operating surface 51 formed at the point where the inclined surface 52 ends. The deformation will return to its initial state.

By returning the deformed pin head 48 enters the operating surface 51 provided in the same shape as the pen head 48, and at the same time the spring 25 is released by the instantaneous loss of resistance in the pin head 48 The pin head 48 is held in intimate contact with the working surface 51 by the retracting force.

As described above, as the pin head 48 moves from the stop surface 50 to the operating surface 51, the switch 26 mounted on the moving block 5 also moves together, and the switch provided in the switch 26. The pin 32 is in an ON state by contacting the terminal pin 13 exposed inward from the terminal 3 provided in the case 4.

And, if you want to switch from the ON (OFF) to the OFF (OFF) state to push the moving block 5 in the case (4) direction once more.

Looking at this in detail, when the moving block 5 is pushed in the case 4 direction, the spring 25 is contracted while the front end surface EP of the pin head 48 is formed on the front surface of the operation surface 51. Since it is located outside the starting point SP of the 55, the pin head 48 is naturally away from the separation surface 55.

The pin heads 48 spaced apart from the spaced surface 55 have a length L enough to accommodate the pin head 48 on the side of the spaced surface 55. Will enter.

Of course, when the pin head 48 moves to the spaced space 56 by the spaced surface 55, deformation may occur due to elasticity, and the space is completely entered into the spaced space 56.

As described above, the degree to which the pin head 48 can enter the otoscope space 56 can be estimated by pushing the moving block 5 toward the case 4 as much as possible without any measurement or indication. This is a problem that can be solved.

When the moving block 5 is pushed to release the moving block 5 that was pressed when the pin head 48 is located in the space 56, the moving block 5 is pushed by the force of the spring 25. It moves in the direction of the stop surface 50 which is an initial position.

As described above, when the return to the initial state of the pin head 48 is completed, the extension portion 46 of the deformed pin body 45 returns to its original state, and the pin head 48 naturally moves to the stop surface 50. Will be done.

As described above, when the pin head 48 moves to the stop surface 50, the switch 26 mounted on the moving block 5 also moves together, and the pin head 48 is in contact with the terminal pin 13 of the terminal 13. The switch pin 32 is also spaced apart from the terminal pin 13 to be turned off (OFF).

FIG. 9 is an exploded perspective view showing another example of a locking type push button switch to which the technique of the present invention is applied, and an LED provided integrally with the terminal 2 in the direction of the case 4 from the outside of the moving block 5; The prism 60 may be further coupled to easily understand the operation state of the push button switch 1 through the light emitted through the light.

By repeating the operation of pushing the moving block 5 as described above, the push button switch 1 is turned on (OFF), the locking pin 42 is formed integrally with the moving block (5). It is designed to increase the assembly and productivity while eliminating unnecessary parts, as well as to facilitate the operability.

The present invention as described above improves the locking means and the terminal configuration, which is very easy to assemble and improves the operation reliability while providing an economical push button switch, as well as minimizing the number of parts, and can be manufactured at low cost. It is devised to have various effects such as the possibility of constructing an automated assembly line by removing components that require attention.
