Description

The present invention relates to a switch device in which an operator returns to its original position by the action of a return spring.

In a switch device in which an operator returns to its original position by the action of a return spring, the operator and the return spring are arranged in series, so that when viewed from the direction of movement of the operator, the return spring It is often provided at the same position as the normal operation position when operating the operator against the biasing force of the return spring (for example, see Patent Document 1). This is because by arranging the operator and the return spring in series, the switch device can be made smaller in the thickness direction. In addition, as long as the normal operating position is pressed when operating the switch device, the point of action of the return spring on the operating element and the operating position will coincide with each other, making it difficult for the operating element to tilt. It is from.

JP2007-227308A

However, even with the above-mentioned switch device, if a position that deviates from the normal operating position (for example, the edge of the operating element) is pressed, there will be a gap between the point of action of the return spring on the operating element and the operating position. This may cause the operator to tilt.

Further, when the operator and the return spring are arranged in series, the height of the device case of the switch device inevitably increases by the space in which the return spring is arranged. Therefore, with a configuration in which the operator and the return spring are arranged in series, there is a limit to miniaturization of the switch device in the height direction.

Therefore, in order to further reduce the size of the switch device in the height direction, it is conceivable to arrange the operator and the return spring in parallel. However, if the operator and the return spring are arranged in parallel, the return spring will be provided at a position that is shifted from the normal operating position, so when operating the switch device, the operator will be forced to A misalignment occurs between the spring and the point of action, which tends to cause the operator to tilt.

In this manner, in any of the above-mentioned switch devices, there is a possibility that the operator may be tilted. When the operator is tilted, a portion of the operator tends to hit the inner wall of the device case. Therefore, if the operator is moved up and down in this state, the operator may rub against the inner surface of the device case, which may cause the operator or the device case to be scratched. Further, if wear particles (resin scum, etc.) are generated due to scraping of the operator or the device case, the wear particles may adhere to the contacts of the switch device and cause poor conduction of the contacts.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a switch device that can suppress the tilting of an operator.

A switch device according to the present invention includes a device case, a first fixed contact and a first movable contact, an operator, and a return spring. Here, the first fixed contact and the first movable contact are contacts that are provided within the device case and can come into contact with each other. The operator is for moving the first movable contact. The return spring is a spring that is provided inside the device case and acts on the operator to return the operator to its original position. The operator is provided with a flange that protrudes from the side surface of the operator, and a holding part that holds the flange is provided on the inner surface of the device case.

According to the above switch device, the flange is always held by the holding part, so even when a force is acting on the operator to tilt it, the holding part holds the flange. It becomes possible to prevent the operator from tilting and separating from the inner surface of the device case.

In the above switch device, the return spring may be provided at a position shifted from the operation position when the operator is operated against the biasing force of the return spring when viewed from the moving direction of the operator. good. In such a positional relationship, a force that tends to tilt the operator in a direction along a straight line passing through the position of the return spring and the operation position is likely to act on the operator. Therefore, in such a configuration, a holding portion may be provided on the inner surface of the device case at a position intersecting a straight line passing through the position of the return spring and the operating position. This makes it easier to prevent the operator from tilting and separating from the inner surface of the device case.

In the above switch device, the flanges may be a pair of left and right flanges protruding from the side surfaces of the operator, and the holding portion may hold the pair of left and right flanges from both sides.

In the above switch device, the flange portion may be provided at a position facing at least the first movable contact on a side surface of the operator. According to this configuration, the insulation distance between the return spring and the first movable contact can be increased by the amount that the flange protrudes from the side surface of the operator.

The switch device may further include a second fixed contact and a second movable contact provided within the device case. Here, the second fixed contact and the second movable contact are contacts that can come into contact with each other, and are provided at positions shifted from the first fixed contact and the first movable contact in the moving direction of the operator. In such a configuration, the operator may be used to move both the first movable contact and the second movable contact. Further, the flange portion may be provided at least at a position facing the first movable contact and a position facing the second movable contact on the side surface of the operator. According to this configuration, the insulation distance between the return spring and the first movable contact can be increased by the amount that the flange protrudes from the side surface of the operator, and the distance between the return spring and the second movable contact can be increased. The insulation distance between can be increased. Therefore, it becomes easier to prevent the first movable contact and the second movable contact from being electrically short-circuited via the return spring.

According to the present invention, it is possible to suppress tilting of an operator in a switch device.

[1] Embodiment FIGS. 1A and 1B are a front view and a plan view, respectively, conceptually showing a switch device according to this embodiment. 2(A) is a cross-sectional view taken along line IIA-IIA in FIG. 1(B), and FIG. 2(B) is a cross-sectional view taken along line IIB-IIB in FIG. 1(B). 3(A) is a cross-sectional view taken along the line III--III in FIG. 2(A), and FIG. 3(B) is an enlarged view of the IIIB region in FIG. 3(A). As shown in these figures, the switch device includes a device case 1, terminal units 2A and 2B, and a switching mechanism 4.

The switch device according to this embodiment is connected between two electric wires W1 and W2 (see FIG. 2(A)), and is a device for selectively switching between electrical short circuit and disconnection between them. . Wire insertion holes 11a and 11b are provided on the left and right sides of the bottom surface 1a of the device case 1, into which the electric wires W1 and W2 are inserted, respectively.

The terminal units 2A and 2B are units that form a strong connection with the electric wires W1 and W2 inserted into the electric wire insertion holes 11a and 11b, respectively, and are generally called a push-in mechanism. In the present embodiment, the terminal units 2A and 2B are installed in installation spaces 10a and 10b, respectively, formed inside the device case 1 on the back side of the wire insertion holes 11a and 11b (see FIG. 2(A)). ).

The switching mechanism 4 is a mechanism for selectively switching between electrical short circuit and disconnection between the terminal units 2A and 2B. In this embodiment, another space 10c isolated from the installation spaces 10a and 10b is formed in the center of the device case 1, and the switching mechanism 4 is constructed in the space 10c (see FIG. 2). (See A) and (B)). Specifically, the switching mechanism 4 includes an operator 40, fixed contacts 41A and 41B, movable contacts 42A and 42B, and a return spring 44.

The operator 40 is an operator for moving the movable contacts 42A and 42B in the vertical direction, and is arranged so that a portion thereof protrudes upward from the top surface 1b of the device case 1 (see FIGS. 2(A) and 2). (See (B)). A guide groove 102 (see FIG. 2B) extending in the moving direction of the operator 40 is formed on the inner surface 101a of the device case 1 facing the front surface 40a of the operator 40. Furthermore, a claw portion 400 that is slidably fitted into the guide groove 102 is formed on the front surface 40a of the operator 40. By engaging the claw portion 400 with the guide groove 102, the vertical movable range of the operator 40 is defined by the guide groove 102.

Fixed contacts 41A and 41B are contacts fixed within the device case 1 (see FIG. 2(A)). In this embodiment, the terminal unit 2A includes a terminal 21A connected to the electric wire W1 inserted into the electric wire insertion hole 11a, and the terminal 21A extends from the installation space 10a and projects into the space 10c. A fixed contact 41A is fixed to a portion of the terminal 21A that protrudes into the space 10c. Further, the terminal unit 2B includes a terminal 21B connected to the electric wire W2 inserted into the electric wire insertion hole 11b, and the terminal 21B extends from the installation space 10b and projects into the space 10c. A fixed contact 41B is fixed to a portion of the terminal 21B that protrudes into the space 10c.

The movable contacts 42A and 42B are each fixed to a conductive member 401 that makes them conductive to each other at a position facing the fixed contacts 41A and 41B (an upper position in FIG. 2A). The movable contacts 42A and 42B are in an open position where they are spaced upward from the fixed contacts 41A and 41B (see FIG. 2(A)), with their positional relationship maintained by the conductive member 401, and the fixed contacts 41A and 42B are in the open position (see FIG. 2A). It moves between a closed position (not shown) in contact with 41B and a closed position (not shown) in accordance with the vertical movement of the operator 40.

More specifically, a guide opening 402 is formed in the operator 40 (see FIGS. 2(A) to 3(A)). Here, the guide opening 402 allows vertical movement of the conductive member 401 relative to the operator 40 and guides the vertical movement with the conductive member 401 passing through the guide opening 402 in the lateral direction. A compression spring 403 is disposed within the guide opening 402 between the top surface of the guide opening 402 and the conductive member 401, so that the conductive member 401 is always directed towards the fixed contacts 41A and 41B ( In the drawing, it is pressed downward). Note that instead of the compression spring 403, a tension spring is arranged between the bottom surface of the guide opening 402 and the conductive member 401, so that the conductive member 401 is always directed toward the fixed contacts 41A and 41B (lower in the drawing). May be pulled towards. In this way, the operator 40 is provided with a plunger mechanism that allows the conductive member 401 to move up and down relative to each other.

According to the plunger mechanism, the following operations are possible. That is, by pushing in the operator 40 and moving it downward, the movable contacts 42A and 42B also move downward in accordance with the operation of the operator 40, and then the movable contacts 42A and 42B become the fixed contacts 41A and 41B, respectively. In the case of contact, the downward movement of the movable contacts 42A and 42B is inhibited by the fixed contacts 41A and 41B even if the operator 40 is pushed further. On the other hand, when the operator 40 is further pushed in after the movable contacts 42A and 42B contact the fixed contacts 41A and 41B, the conductive member 401 moves relatively upward within the guide opening 402. As a result, the compression spring 403 is compressed by the amount of movement of the conductive member 401, and the elastic force of the compression spring 403 at that time acts as a force to press the movable contacts 42A and 42B toward the fixed contacts 41A and 41B of the conductive member. 401 to the movable contacts 42A and 42B. Therefore, a good connection state is likely to be formed between the fixed contacts 41A and 41B and the movable contacts 42A and 42B when these contacts are closed.

According to the configuration of the switching mechanism 4, electrical short-circuiting and disconnection between the terminal units 2A and 2B are selectively switched according to the vertical movement of the operator 40. In this embodiment, the switching mechanism 4 is further configured such that the movable contacts 42A and 42B are normally open contacts.

Specifically, a return spring 44 is provided inside the device case 1, and the return spring 44 acts on the operator 40 (see FIGS. 2(B) to 3(B)). Here, the return spring 44 acts on the operator 40 to return the operator 40 to its original position protruding upward from the top surface 1b (in this embodiment, the claw portion 400 is placed at the upper end of the guide groove 102). This is a compression spring that returns the robot to the position it reached.

More specifically, a groove 404 extending vertically is formed on the back surface 40b of the operator 40, and the return spring 44 is arranged in the groove 404, so that the return spring 44 is arranged in parallel with the operator 40. are arranged (see FIGS. 2(B) to 3(B)). In this embodiment, a groove 404 is formed in a region of the back surface 40b of the operator 40 that is lower than the top surface 1b of the device case 1 when the operator 40 is in the original position. . A projection 405 inserted into the upper end of the return spring 44 is formed on the upper end surface of the groove 404 in order to cause the return spring 44 to act on the operator 40 . In addition, a return spring 44 is provided on the inner surface 101b of the device case 1 facing the back surface 40b of the operator 40 in order to compress the return spring 44 between it and the protrusion 405 when the operator 40 moves downward. A receiving portion 103 for receiving the lower end portion is formed to protrude into the groove portion 404 .

According to such a configuration, the movable contacts 42A and 42B are always urged toward the open position via the operator 40. Further, since the operator 40 and the return spring 44 are arranged in parallel, it is possible to reduce the size of the switch device in the height direction. On the other hand, when the switch device is viewed from the direction of movement of the operator 40 (see FIG. 3(A)), the return spring 44 is energized when the operator 40 is operated against the biasing force of the return spring 44. is provided at a position shifted from the normal operating position Pc (the normal position where force is applied from the outside to the operator 40 when moving the operator 40 downward; see also FIG. 2(B)). It turns out. For this reason, when the switch device is operated, there is a misalignment between the operating position at that time and the point of action of the return spring 44 on the operator 40, which tends to cause the operator 40 to tilt.

In this embodiment, the return spring 44 is a compression spring, and since the return spring 44 is disposed on the rear surface 40b side of the operator 40, the upper part of the operator 40 is separated from the inner surface 101b of the device case 1. This makes it more likely that the vehicle will tilt toward the front (tilting forward). In other words, when viewed from the moving direction of the operator 40, the operator 40 has a direction along a straight line passing through the position of the return spring 44 and the normal operation position Pc (in this embodiment, the return spring 44 A force that tends to tilt the operator 40 in a direction (direction from the position toward the normal operating position Pc) is more likely to act. When the operator 40 tilts, a portion of the operator 40 tends to hit the inner surface 101b of the device case 1. Therefore, if the operator 40 is moved up and down in this state, the operator 40 will rub against the inner surface 101b of the device case 1, which may cause the operator 40 or the device case 1 to be scratched. In addition, if wear particles (resin scum, etc.) are generated due to the operation element 40 or device case 1 being scraped, the wear particles will adhere to the contacts (fixed contacts and movable contacts) of the switch device, causing poor conduction of the contacts. There is a risk.

Therefore, in this embodiment, the following structure is constructed in the switch device as a tilt suppression structure for suppressing the tilt of the operator 40 (see FIG. 3(B)). That is, on the same side of the operator 40 as the return spring 44 (i.e., on the rear surface 40b side of the operator 40), the operator 40 has a hole protruding from the left side 40c and right side 40d of the operator 40. A pair of left and right flanges 45A and 45B are provided, and a holding portion 104 that holds the pair of left and right flanges 45A and 45B from both sides is provided on the inner surface 101b of the device case 1. In other words, the holding portion 104 is located on the inner surface 101b of the device case 1 at a position that intersects a straight line passing through the position of the return spring 44 and the normal operating position Pc when viewed from the moving direction of the operator 40. It is provided.

Specifically, the collar portions 45A and 45B are formed so that their back surfaces are flush with the back surface 40b of the operator 40. When holding the flange parts 45A and 45B, the holding part 104 does not prevent the flange parts 45A and 45B from sliding in the vertical direction, and also allows the back surface 40b of the operator 40 to come into contact with the inner surface 101b of the device case 1. Or, it is configured to be able to bring them close together and maintain that state. In this embodiment, the holding part 104 has a pair of left and right guide grooves 104A and 104B, and the flanges 45A and 45B are fitted into the guide grooves 104A and 104B, respectively, so that the flanges 45A and 45B are connected to the holding part. 104 so as to be slidable.

According to such a tilt prevention structure, the return spring 44 is provided at a position deviated from the normal operating position Pc, so that even when a force that tends to tilt the operator 40 is acting on the operator 40, Also, since the pair of left and right flanges 45A and 45B are always held by the holding part 104, the holding part prevents the operator 40 from tilting and separating from the inner surface 101b of the device case 1. This makes it difficult for the operator 40, the device case 1, etc. to be scratched, thereby suppressing the generation of abrasion powder and making it difficult for poor conduction of the contacts to occur.

In addition, in such a configuration, in order to efficiently suppress the tilt of the operator 40, the upper part, which is the largest distance away from the inner surface 101b of the device case 1 when the operator 40 is tilted, is held by the holding part 104. May be retained. For example, the holding portion 104 is provided at least at an upper position on the inner surface 101b of the device case 1. Note that FIG. 2A shows a case where the holding portion 104 is provided at a relatively upper position on the inner surface 101b of the device case 1.

In this way, according to the switch device of this embodiment, it is possible to suppress the tilt of the operator 40.

Furthermore, in the switch device equipped with the above-mentioned tilt prevention structure, the pair of left and right flanges 45A and 45B are located at positions facing at least the movable contacts 42A and 42B of the left side surface 40c and right side surface 40d of the operator 40. It is preferable that it is provided. More preferably, the flanges are arranged so that the flanges 45A and 45B always face the movable contacts 42A and 42B, no matter where the operator 40 and the movable contacts 42A and 42B are located within their movable ranges. The portions 45A and 45B are provided on the left side surface 40c and the right side surface 40d in consideration of their positions, lengths, etc. (see FIG. 2(A)).

According to such a configuration, the insulation between the return spring 44 and the conductive member 401 (movable contacts 42A and 42B) is reduced by the amount that the pair of left and right flanges 45A and 45B protrude from the left side surface 40c and the right side surface 40d. The distance can be increased (see FIG. 3(B)). Here, the insulation distance is the length of the shortest path Ri from the conductive member 401 to the return spring 44, bypassing the operator 40, which is an insulating member, and in this embodiment, the shortest path Ri is This is a path from the return spring 44 to the conductive member 401 via the back surface 40b and the left side surface 40c or right side surface 40d of the child 40.

[2] Modified Examples [2-1] First Modified Example FIG. 4 is a cross-sectional view of a switch device according to a first modified example, taken along the same line as the IIB-IIB line in FIG. 1(B). In the switch device of FIG. 4, the operator 40 and the return spring 44 are arranged in series, so that the return spring 44 is provided at the same position as the normal operating position Pc. According to such a configuration, as long as the normal operating position Pc is pressed during operation of the switch device, the point of action of the return spring 44 on the operator 40 and the operating position coincide with each other. The operator 40 is less likely to be tilted. On the other hand, even with such a switch device, if a position shifted from the normal operating position Pc (operating position Pd, for example, the edge of the operator 40) is pressed, as shown in FIG. A deviation may occur between the point of action of the return spring 44 on the operator 40 and the operating position, which may cause the operator 40 to tilt.

Therefore, it is preferable that the switch device shown in FIG. 4 also be provided with the tilt suppressing structure described in the above embodiment, thereby making it possible to suppress the tilt of the operator 40.

[2-2] Second Modification The above-described switch device may be modified into a switch device configured by stacking two devices with the same configuration, one above the other. FIG. 5 shows an example of such a switch device as a first modification, and is a cross-sectional view taken along the same line as the IIA-IIA line in FIG. 1(B). Further, FIG. 6 is a cross-sectional view of the switch device according to the first modification, taken along the same line as the IIB-IIB line in FIG. 1(B). 5 and 6, the switch device shown in FIGS. 2A and 2B is shown as a first stage, and a second stage switch device is shown below.

Specifically, the device case 1 shown in FIGS. 2(A) and 2(B) is used as the first stage part 131, and the bottom surface 131a (the bottom surface 1a of the device case 1 shown in FIG. 2(A) A second stage portion 132 extends downward from the area between the left and right wire insertion holes 11a and 11b of the corresponding portion. The bottom surface 132a of the second stage portion 132 is provided with wire insertion holes 14a and 14b on the left and right, into which wires W3 and W4, which are different from the wires W1 and W2 inserted into the wire insertion holes 11a and 11b, are inserted. (See Figure 5).

Similarly to the first stage part 131, in the second stage part 132, terminal units 2A and 2B, which are push-in mechanisms, are provided corresponding to the left and right wire insertion holes 14a and 14b, respectively. (See Figure 5).

Furthermore, the switching mechanism 4 is configured to electrically short-circuit and disconnect between the terminal units 2A and 2B in the second-stage portion 132 (i.e., between the fixed contacts 41A and 41B and the movable contacts 42A and 42B in the second-stage portion 132). (contact and separation) and electrical short circuit and disconnection between the terminal units 2A and 2B in the first stage portion 131 are configured to be switched in conjunction with the vertical movement of one operator 40. (See Figure 5).

Specifically, within the device case 1, the space 10c extends downward from the first stage portion 131 to the second stage portion 132 (see FIGS. 5 and 6). Further, the operator 40 and the return spring 44 also extend downward within the space 10c to the second stage portion 132. The operator 40 is provided with movable contacts 42A and 42B in the first stage part 131 and the second stage part 132, respectively, and allows relative vertical movement of the conductive member 401 that supports them. A plunger mechanism is provided.

In such a two-stage switch device, the fixed contacts 41A and 41B and the movable contacts 42A and 42B of the first stage part 131 and the fixed contacts of the second stage part 132 are fixed in the space 10c of the device case 1. The contacts 41A and 41B and the movable contacts 42A and 42B are provided at positions shifted from each other in the moving direction of the operator 40. Further, the operator 40 is used to move both the movable contacts 42A and 42B of the first stage portion 131 and the movable contacts 42A and 42B of the second stage portion 132.

In such a configuration, the pair of left and right brim portions 45A and 45B face at least the movable contacts 42A and 42B of the first stage portion 131 of the left side surface 40c and right side surface 40d of the operator 40. It is preferable that the movable contacts 42A and 42B of the second stage portion 132 be provided at positions facing the movable contacts 42A and 42B. More preferably, the operating element 40, the movable contacts 42A and 42B of the first stage part 131, and the movable contacts 42A and 42B of the second stage part 132 are located at any position within their movable ranges. Also, the flanges 45A and 45B are arranged so that the flanges 45A and 45B always face both the movable contacts 42A and 42B of the first stage part 131 and the movable contacts 42A and 42B of the second stage part 132. They are provided on the left side surface 40c and the right side surface 40d, taking into consideration the positions and lengths of (see FIG. 2(A)).

As an example, in the switch device shown in FIG. 5, the flanges 45A and 45B extend from a position facing the movable contacts 42A and 42B of the first stage part 131 to a position facing the movable contacts 42A and 42B of the second stage part 132. It extends continuously downward.

According to such a configuration, the return spring 44 and the conductive member 401 (movable contact 42A and the movable contact 42A and 42B), and the insulation distance between the return spring 44 and the conductive member 401 (movable contacts 42A and 42B) of the second stage portion 132 can be increased. . Therefore, electrical short circuit between the conductive member 401 of the first stage portion 131 and the conductive member 401 of the second stage portion 132 via the return spring 44 can be easily prevented.

[2-2] Other Modifications The terminal unit 2A is not limited to the push-in mechanism, as long as it can form a strong connection between the electric wire W1 and the terminal 21A, and the electric wire W1 and the terminal 21A can be connected with screws. A screw fastening mechanism or the like may be used to form a strong connection. The same applies to the terminal unit 2B.

In the switch device of the above embodiment (FIG. 2A), the movable contacts 42A and 42B are not limited to normal normally open contacts, but are early made normally open contacts (contacts that close earlier than normal normally open contacts). ), or may be configured to be a normally closed contact. Further, in the switch device of the first modification example (FIG. 5), at least one of the first stage portion 131 and the second stage portion 132 is not limited to a normal normally open contact, but may be an early made normally open contact. It may be configured to be an open contact or may be configured to be a normally closed contact.

In the switch device described above, the return spring 44 may be a tension spring, a plate spring, or the like. When a tension spring is used as the return spring 44, the direction of inclination of the operator 40 is opposite to when a compression spring is used. In this case, the tilt prevention structure constituted by the left and right pair of flanges 45A and 45B and the holding part 104 is located on the opposite side of the operator 40 from the position of the return spring 44 (i.e., on the front side 40a of the operator 40). may be provided. Further, the tilt restraining structure may be provided on both the same side and the opposite side of the return spring 44 with respect to the operator 40.

In the switch device described above, the tilt prevention structure is not limited to the one in which the left and right pair of flanges 45A and 45B are held by the holding part 104, but the operator 40 is provided with one flanged part, and the one flanged part is held in the holding part. It may be changed as appropriate to the one held in . Further, the flange portion and the holding portion constituting the tilt prevention structure may be appropriately changed to a configuration other than the above-mentioned configuration (shape, etc.) as long as the tilting of the operator 40 can be suppressed.

The above-described embodiments and modifications should be considered to be illustrative in all respects and not restrictive.
