Detailed Description
In order that the invention may be more particularly understood, an embodiment thereof will be described with reference to the accompanying drawings.
(one embodiment)
According to the present embodiment, the push switch 1 is a push switch mounted in a vehicle door handle device, not shown. When the user operates the door lock device, the locking or unlocking of the door can be performed by pressing the button 50 of the push button switch 1 exposed from the vehicle door handle device.
The push switch 1 includes: the switch element 10, the two terminal members 20A, 20B, the two lead wires 30, the switch case 40, the push button 50, and the cover member 60.
The switching element 10 includes a cylindrical operation portion 11, a rectangular parallelepiped body portion 12, and four connection terminals 13. The operation portion 11 protrudes upward from inside the main body portion 12, is configured to be movable in the up-down direction of fig. 7, and is pressed upward in fig. 7 by an unillustrated elastic member inside the main body portion 12. The connection terminal 13 extends downward from the body portion 12.
The switch element 10 is disposed in a space formed by a switch case 40 and a push button 50 described later.
The terminal members 20A, 20B are formed by processing a conductive metal plate, and have a flat surface portion 21, and a first hanging portion 22 and a second hanging portion 23 hanging from both ends of the flat surface portion 21.
In the planar portion 21, a first connection portion 24 for electrically connecting the connection terminals 13 of the switching element 10 in a non-soldering manner is formed. The first connection portion 24 is formed with a tongue piece that is formed in a cantilever shape and is cut in three circumferential directions. The tongue is bent to be slightly downwardly inclined.
Further, in the flat portion 21, a notch portion 26 into which guide walls 47c and 47d provided in the switch case 40 described later are fitted is formed.
The first hanging-down portion 22 is formed with a second connection portion 25 for non-soldering electrical connection of the lead 30. In the second connection portion 25, a longitudinal slit having a width slightly narrower than the diameter of the core wire of the lead wire 30 formed by insulatively covering the core wire is formed.
The second hanging-down portion 23 is shorter than the first hanging-down portion 22, and is formed in a slightly curved shape so as to be fixable to a groove portion 46b of the switch case 40 described later.
The switch case 40 is integrally molded from a hard resin into a square tube shape having a bottom, has a bottom surface and a side surface, and has an opening portion on the upper surface.
In the upper portions of the two opposite side surfaces of the switch case 40, locking claws 41 that lock locking portions 61 of a cover member 60 described later are provided.
A circular insertion hole 42a for inserting the distal ends of the two lead wires 30 into the switch case is formed in one side surface of the switch case 40 where the locking claw 41 is not provided. The diameter of the insertion hole 42a is slightly larger than the diameter of the lead 30.
Further, in one side surface of the switch case 40, a resin filling chamber 42 is provided to surround the insertion hole 42 a. The resin filling chamber 42 is in the form of a square tube protruding from one side surface of the switch case 40 to the outside, and is filled with resin for waterproofing.
Inside the switch case 40, three standing walls 43a, 43b, and 43c parallel to the insertion direction of the lead wire 30 (the left-right direction of the paper plane of fig. 8) and one standing wall 43d orthogonal to the insertion direction of the lead wire 30 are provided.
A part of the upper surface of the standing walls 43a, 43B, 43c (hatched portion in fig. 8) serves as a second support portion 45 that supports the flat surface portion 21 of the terminal members 20A, 20B.
The standing walls 43a, 43B, and 43c are provided with groove portions 46a into which the first hanging-down portions 22 of the terminal members 20A and 20B are inserted and fitted, and groove portions 46B into which the second hanging-down portions 23 of the terminal members 20A and 20B are fixed. The groove 46a is provided in the middle of the first support section 44 in the left-right direction of the sheet of fig. 8.
These grooves 46a, 46B are formed linearly, and have a width (width in the left-right direction of the drawing sheet of fig. 8) corresponding to the thickness of the first hanging-down portion 22 and the second hanging-down portion 23 of the terminal members 20A, 20B.
In the upper surfaces of the upright walls 43a, 43b, 43c, guide walls 47a, 47b, 47c, 47d for guiding the main body portion 12 of the switching element 10 from the side are provided. Also, the central portion of the standing wall 43a is formed to be partially high, and the guide walls 47a, 47b are provided in the high portion.
The push button 50 is made of a soft resin having elasticity such as rubber, and includes an upper operation wall 51 and a side peripheral wall 52 depending from a peripheral edge of the upper operation wall 51.
The button 50 is mounted on the upper portion of the switch case 40 to close the opening portion of the switch case 40. Specifically, the side peripheral wall 52 is fitted into a stepped portion provided in the upper outer periphery of the switch case 40, and the cover member 60 is fitted into the outer periphery of the side peripheral wall 52. Further, the locking portion 61 of the cover member 60 is locked by the locking claw 41 of the switch housing 40, thereby fixing the push button 50 and the cover member 60 in the switch housing 40.
In addition, in the case of mounting the push switch 1 to a door handle, not shown, it is mounted inside the door handle in such a manner that the upper operation wall 51 of the push button 50 is exposed to the outside.
Next, a method of assembling the push switch 1 of the present embodiment will be described.
First, the two lead wires 30 are inserted into the switch case 40 through the insertion holes 42 a. Subsequently, the tip end portion of the lead 30 is pressed from above and into the first support portion 44 (see fig. 10). Thereby, the lead 30 is fixed in the switch case 40 and is not easily detached.
Subsequently, the first hanging-down portions 22 and the second hanging-down portions 23 of the terminal members 20A, 20B are respectively fitted into the groove portions 46a and 46B of the switch case 40 (refer to fig. 11).
When the first hanging-down portions 22 of the terminal members 20A, 20B are fitted into the groove portions 46a, the tip end portions of the leads 30 are fitted into the second connecting portions 25 formed by the longitudinal slits formed in the first hanging-down portions 22. At this time, since the slit width of the second connection portion 25 is slightly narrower than the diameter of the core wire of the lead wire 30, both side portions of the slit of the second connection portion 25 bite into the insulating coating material, so that the core wire of the lead wire 30 is electrically connected to the terminal members 20A, 20B.
When the second hanging-down portions 23 of the terminal members 20A, 20B are fitted into the groove portions 46B, the second hanging-down portions 23 having a slightly curved shape are deformed in accordance with the linear groove portions 46B. Therefore, the terminal members 20A, 20B are fixed to the switch case 40 by the elastic force generated by the deformation of the second hanging-down portion 23, and do not float and fall off from the switch case 40. Thus, the groove 46B of the switch case 40 functions as a fixing portion for fixing the terminal members 20A, 20B.
Further, when the first hanging-down portion 22 and the second hanging-down portion 23 of the terminal members 20A, 20B are fitted into the groove portions 46a and 46B, respectively, the flat surface portion 21 is placed on the second support portion 45 of the switch case 40 while the guide walls 47c, 47d are partially fitted into the cutout portions 26. In this way, the terminal members 20A, 20B are fixed in the switch case 40 in a stable state without generating positional deviation in the horizontal direction and floating up in the vertical direction.
Subsequently, the switching element 10 is assembled. Specifically, the four connection terminals 13 of the switching element 10 are inserted into a total of four first connection portions 24 formed in the planar portions 21 of the terminal members 20A, 20B (refer to fig. 12).
When the connection terminal 13 is inserted into the first connection portion 24, the tongue piece of the first connection portion 24 is deformed downward, and the connection terminal 13 is pressed and fixed to the tongue piece by the elastic force generated by the deformation, so that the connection terminal 13 is electrically connected to the terminal parts 20A, 20B.
Further, when the connection terminal 13 is inserted into the first connection portion 24, the rectangular parallelepiped body portion 12 of the switch element 10 is surrounded in a close contact state by the guide walls 47a, 47b, 47c, 47d of the switch case 40. In this way, the side surfaces of the switching element 10 in the four directions are restricted, so that the wobbling of the switching element 10 can be prevented, and the reliability of the electrical connection between the connection terminal 13 and the terminal members 20A, 20B can be improved.
Subsequently, after the push button 50 is attached so as to close the opening of the switch case 40, the cover member 60 is attached, and finally, the resin filling chamber 42 of the switch case 40 is filled with resin (not shown).
In the push switch 1 of the present embodiment configured in this manner, when the upper operation wall 51 of the push button 50 is pressed downward from above in fig. 7, the upper operation wall 51 is elastically deformed to push the operation portion 11 of the switching element 10 downward, and the switch is turned on, so that a signal is transmitted to the outside through the lead wire 30.
When the pressing operation of the upper operation wall 51 is released, the soft button 50 returns to the initial state by the restoring force, and the operation portion 11 of the switch element 10 also returns upward to close the switch.
According to the push switch 1 of the present embodiment described above, the connection terminal 13 of the switching element 10 and the lead wire 30 can be electrically connected without soldering by the first connection portion 24 and the second connection portion 25 formed in the terminal members 20A and 20B.
Further, since the switch case 40 has the first support part 44 that restricts the front end portion of the lead wire 30 inserted into the inside, the lead wire 30 is prevented from twisting when the terminal members 20A, 20B are inserted, so that the electrical connection of the second connection part 25 and the lead wire 30 can be performed simply and with high reliability.
Further, since the flat surface portions 21 of the terminal members 20A, 20B are supported by the second support portion 45 of the switch case 40, and the lead wires 30 whose tip portions are regulated by the first support portions 44 are fitted into the second connection portions 25 of the terminal members 20A, 20B, the terminal members 20A, 20B are prevented from being warped or twisted when the connection terminals 13 of the switching element 10 are inserted into the first connection portions 24. Therefore, the electrical connection between the first connection portion 24 of the terminal members 20A, 20B and the connection terminal 13 of the switching element 10 can be performed easily and with high reliability.
Therefore, according to the present embodiment, the manufacturing can be simplified without welding, and a highly reliable push switch can be realized with a small number of parts.
In the push switch 1 of the present embodiment, since the groove 46a into which the first hanging-down part 22 of the terminal members 20A, 20B is fitted is provided in the switch case 40, the positions of the terminal members 20A, 20B can be easily determined, so that the electrical connection between the second connection part 25 and the lead wire 30 can be extremely easily performed.
In the push switch 1 of the present embodiment, since the groove 46B into which the second hanging-down part 23 of the fixed terminal members 20A, 20B is fitted is provided in the switch case 40, the terminal members 20A, 20B can be firmly fixed to the switch case 40, and a push switch with higher reliability can be realized.
In the push switch 1 of the present embodiment, the resin filling chamber 42 provided so as to surround the insertion hole 42a into which the lead 30 is inserted is filled with the resin, so that water can be effectively prevented from entering the inside of the switch case 40 in which the switch element 10 is disposed, and a push switch having excellent water resistance can be realized.
Although one embodiment of the present invention has been described above, the present invention is not limited to this embodiment, and can be appropriately modified without departing from the scope of the present invention.
Specifically, for example, as for the first connection portions 24 provided in the terminal members 20A, 20B, any shape of tongue piece may be employed as long as it can be electrically connected to the connection terminals 13 in a non-soldered manner.
In addition, as for the second connection portion 25 provided in the terminal members 20A, 20B, any shape of slit or cutout may be employed as long as it can be electrically connected to the lead 30 in a non-welding manner.
Further, the first support portion 44 of the switch case 40 is preferably configured to press and fix the tip of the lead 30 from above, for simplicity and reliability, but may be configured to support only the tip of the lead 30 from below or to insert only the tip of the lead 30.
Further, regarding the structure for fixing the terminal members 20A, 20B to the switch case 40, the elastic force generated by the deformation of the second hanging-down portion 23 is preferable because of simplicity, but a form of providing a locking claw for locking the terminal member to the switch case 40 or pressing only a part of the terminal member may be adopted. In order to more reliably fix the terminal members 20A and 20B, the first hanging-down portion 22 is preferably slightly bent in the same manner as the second hanging-down portion 23 so as to be fixable to the groove portion 46a of the switch case 40.
