Description

Switchgear

The present invention relates to a switch device in which an operating element is restored to its original position by the action of a return spring.

In the switch device in which the operating element returns to the original position by the action of the return spring, the operating element and the return spring are arranged in series, so that it is mostly the following situation, that is, when viewed from the moving direction of the operating element, the return spring It is set at the same position as the normal operation position when the operating element is operated against the urging force of the return spring (for example, refer to Patent Document 1). This is because by arranging the operating element and the return spring in series, the switch device can be miniaturized in the thickness direction. In addition, as long as the normal operating position is pressed during the operation of the switch device, the action point of the return spring and the operating position of the opposing operating member coincide with each other. Therefore, it is difficult for the operating member to tilt. [Prior Technical Literature] [Patent Literature]

[The problem to be solved by the invention]

However, even in the above-mentioned switch device, when a position shifted from the normal operating position (for example, the edge of the operating member, etc.) is pressed, there is a deviation between the action point of the return spring of the relative operating member and the operating position. For this reason, there is a risk of tilting the operating member.

In addition, when the operating element and the return spring are arranged in series, the height dimension of the device box of the switch device will inevitably become larger according to the space in which the return spring is arranged. Therefore, in the configuration in which the operating member and the return spring are arranged in series, there is a limit to the miniaturization of the switch device in the height direction.

Therefore, in order to further miniaturize the switch device in the height direction, it is considered that the operating element and the return spring are arranged in parallel. However, if the operating element and the return spring are arranged in parallel, the return spring is provided at a position shifted from the normal operating position. Therefore, during the operation of the switch device, the operating position and the relative operating element There is a deviation between the action points of the return spring, and this is the reason, and the operating member is likely to tilt.

As such, in any of the above-mentioned switch devices, there is a possibility that the operating member may tilt. If the operating member is tilted, a part of the operating member is likely to touch the inner wall of the device box. Therefore, if the operating member is moved up and down in this state, the operating member will rub against the inner surface of the device box. This is the cause, and the operating member or the device box may wear out. In addition, if abrasion powder (resin chips, etc.) is generated due to wear of the operating element or the device box, the abrasion powder may adhere to the contacts of the switch device and cause poor conduction of the contacts.

Therefore, the object of the present invention is to provide a switch device capable of suppressing the tilt of the operating member. [Means to Solve the Problem]

The switch device of the present invention includes a device box, a first fixed contact and a first movable contact, an operating element, and a return spring. Here, the first fixed contact and the first movable contact are contact points that are provided in the device box and can contact each other. The operating element is used to move the first movable contact. The return spring is a spring that is arranged in the device box and acts on the operating element to return the operating element to its original position. In addition, the operating member is provided with a flange portion protruding from the side surface of the operating member, and a holding portion for holding the flange portion is provided on the inner surface of the device box.

According to the above-mentioned switch device, the flange is always held by the holding part. Therefore, even when a force to tilt the operating element is applied to the operating element, the holding part can hold the flange to suppress the operating element. Inclined and separated from the inner surface of the device box.

In the above-mentioned switch device, when viewed from the moving direction of the operating element, the return spring may be provided at a position shifted from the operating position when the operating element is operated against the force of the return spring. In the case of such a positional relationship, it is easy to act on the operating member to tilt the operating member in a direction along the straight line passing through the position of the return spring and the operating position. Therefore, in such a configuration, a holding portion may be provided at a position where a straight line passing through the position of the return spring and the operation position intersects on the inner surface of the device case. Thereby, it is easy to prevent the operating member from being inclined and separating from the inner surface of the device box.

In the above-mentioned switch device, the flange portion may be a pair of left and right flange portions protruding from the side surface of the operating member; the holding portion may be a flange portion that holds a pair of left and right from both sides.

In the above-mentioned switch device, the flange portion may be provided at a position opposed to at least the first movable contact on the side surface of the operating member. With this configuration, the insulation distance between the return spring and the first movable contact can be increased according to the amount of the flange portion protruding from the side surface of the operating element.

The above-mentioned switch device may further include a second fixed contact and a second movable contact provided in the device box. Here, the second fixed contact and the second movable contact are contacts that can be in contact with each other, and are provided at positions offset from the first fixed contact and the first movable contact in the moving direction of the operating member. Furthermore, in such a configuration, the operating element may be used to move both the first movable contact and the second movable contact. In addition, the flange portion may be provided on the side surface of the operating member at least at a position facing the first movable contact and a position facing the second movable contact. With this structure, the insulating distance between the return spring and the first movable contact can be increased according to the amount of the flange portion protruding from the side of the operating element, and the return spring and the second movable contact can be increased The insulation distance becomes larger. According to this, it is easy to suppress that the first movable contact and the second movable contact are electrically short-circuited via the return spring. [Effects of the invention]

According to the present invention, the tilt of the operating member can be suppressed in the switch device.

[1] Implementation form Fig. 1 (A) and Fig. 1 (B) are respectively conceptually showing a front view and a plan view of the switch device of this embodiment. Fig. 2(A) is a cross-sectional view taken from the line IIA-IIA of Fig. 1(B), and Fig. 2(B) is a cross-sectional view taken from the line IIB-IIB of Fig. 1(B). Fig. 3(A) is a cross-sectional view taken from line III-III of Fig. 2(A), and Fig. 3(B) is an enlarged view of area IIIB of Fig. 3(A). As shown in these figures, the switch device includes a device box 1, terminal units 2A and 2B, and a switch mechanism 4.

The switch device of this embodiment is connected between the two wires W1 and W2 (refer to Figure 2(A)) to selectively switch the electrical short-circuit and disconnection between them. Furthermore, on the bottom surface 1a of the device box 1, wire insertion holes 11a and 11b into which the power supply wires W1 and W2 are inserted are respectively provided on the left and right.

The terminal units 2A and 2B are units that form a firm connection state of the wires W1 and W2 inserted into the wire insertion holes 11a and 11b, respectively, and are generally called push-in mechanisms. Furthermore, in this embodiment, the terminal units 2A and 2B are installed in the device box 1 in the installation spaces 10a and 10b formed at the innermost sides of the wire insertion holes 11a and 11b (see FIG. 2(A)).

The switch mechanism 4 is a mechanism for selectively switching the electrical short-circuit and disconnection between the terminal units 2A and 2B. In this embodiment, another space 10c separated from the installation spaces 10a and 10b is formed in the central part of the device box 1, and the switch mechanism 4 is constructed in this space 10c (refer to Figs. 2(A) and 2(B)) ). Specifically, the switch mechanism 4 is composed of an operating element 40, fixed contacts 41A and 41B, movable contacts 42A and 42B, and a return spring 44.

The operating element 40 is an operating element used to move the movable contacts 42A and 42B in the vertical direction, and is arranged so that a part of it protrudes upward from the top surface 1b of the device box 1 (refer to Figure 2(A) and Figure 2(B)) . Furthermore, on the inner surface 101a of the device case 1 facing the front surface 40a of the operating member 40, a guide groove 102 extending in the moving direction of the operating member 40 is formed (refer to FIG. 2(B)). In addition, on the front surface 40a of the operating member 40, a claw portion 400 slidably fitted in the guide groove 102 is formed. Furthermore, by the engagement of the claw portion 400 with the guide groove 102, the movable range of the operating member 40 in the up and down direction is defined by the guide groove 102.

The fixed contacts 41A and 41B are fixed to the contacts in the device box 1 (refer to Figure 2(A)). In this embodiment, the terminal unit 2A includes a terminal 21A connected to the wire W1 inserted in the wire insertion hole 11a, and the terminal 21A extends from the installation space 10a and protrudes into the space 10c. In addition, a fixed contact 41A is fixed to a portion of the terminal 21A protruding into the space 10c. In addition, the terminal unit 2B includes a terminal 21B connected to the wire W2 inserted into the wire insertion hole 11b, and the terminal 21B extends from the installation space 10b and protrudes into the space 10c. In addition, a fixed contact 41B is fixed to a portion of the terminal 21B protruding into the space 10c.

The movable contacts 42A and 42B are respectively fixed on the conductive member 401 that connects them to each other at positions facing the fixed contacts 41A and 41B (in FIG. 2(A), the upper position). In addition, the movable contacts 42A and 42B are in a state where the positional relationship between each other is maintained by the conductive member 401, in an open position separated upward from the fixed contacts 41A and 41B (refer to FIG. 2(A)), and the fixed contact The closed position (not shown) contacted by the points 41A and 41B moves according to the up and down movement of the operating member 40.

More specifically, a guide opening 402 is formed in the operating element 40 (refer to FIGS. 2(A) to 3(A)). Here, the guide opening 402 is a state in which the conductive member 401 penetrates the guide opening 402 in the horizontal direction, so that the conductive member 401 can move up and down relative to the operating member 40, and guide the up and down. Mover. Moreover, in the guide opening 402, a compression spring 403 is arranged between the top surface of the guide opening 402 and the conductive member 401, whereby the conductive member 401 always faces the fixed contacts 41A and 41B (in the drawing The middle is the bottom) is pressed. In addition, instead of the compression spring 403, the tension spring can be arranged between the bottom surface of the guide opening 402 and the conductive member 401, whereby the conductive member 401 always faces the fixed contacts 41A and 41B (in the figure, it is Below) is stretched. In this way, the operating member 40 is provided with a plunger mechanism that enables the relative up and down movement of the conductive member 401.

Furthermore, according to the above-mentioned bolt mechanism, the next operation can be performed. That is, the operating member 40 is pushed in to move downward, whereby the movable contacts 42A and 42B also move downward in accordance with the action of the operating member 40, and thereafter, the movable contacts 42A and 42B are connected to the fixed contacts respectively When the points 41A and 41B are in contact, even if the operating element 40 is pushed in further, the downward movement of the movable contacts 42A and 42B can be suppressed by the fixed contacts 41A and 41B. On the other hand, after the movable contacts 42A and 42B are in contact with the fixed contacts 41A and 41B, when the operating member 40 is pushed in further, the conductive member 401 moves relatively upward in the guide opening 402. Thereby, the compression spring 403 is compressed according to the amount of movement of the conductive member 401, and the elastic force of the compression spring 403 at this time is used as a force to press the movable contacts 42A and 42B toward the fixed contacts 41A and 41B, and the conductive member 401 is used to compress the compression spring 403. Applied to the movable contacts 42A and 42B. Accordingly, it is easy to form a good connection state between the fixed contacts 41A and 41B and the movable contacts 42A and 42B when they are closed.

According to the configuration of such a switch mechanism 4, the electrical short-circuit and disconnection between the terminal units 2A and 2B are selectively switched according to the up and down movement of the operating member 40. In this embodiment, the switch mechanism 4 is further configured such that the movable contacts 42A and 42B become normally open contacts.

Specifically, a return spring 44 is provided in the device case 1, and the return spring 44 acts on the operating element 40 (refer to FIGS. 2(B) to 3(B) ). Here, the return spring 44 acts on the operating member 40 to return the operating member 40 to its original position protruding upward from the top surface 1b (in this embodiment, the claw portion 400 reaches the guide groove 102 The upper end position) of the compression spring.

More specifically, a groove 404 extending vertically is formed on the back 40b of the operating element 40, and a return spring 44 is arranged in the groove 404, whereby the return spring 44 is arranged in parallel with the operating element 40 (see FIG. 2(B) ) ~ Figure 3 (B)). In this embodiment, in the back surface 40b of the operating member 40, when the operating member 40 is in the above-mentioned original position, a groove portion 404 is formed in an area below the top surface 1b of the device box 1. Furthermore, a protrusion 405 inserted into the upper end of the return spring 44 in order to cause the return spring 44 to act on the operating member 40 is formed on the upper end surface of the groove 404. Furthermore, in order to compress the return spring 44 between the protrusion 405 and the receiving portion 103 that receives the lower end of the return spring 44 when the operating member 40 is moved downward, in a state of protruding into the groove portion 404, It is formed on the inner surface 101b of the device box 1 opposite to the back surface 40b of the operating member 40.

According to such a structure, the movable contacts 42A and 42B are in a state in which the operating member 40 always acts toward the open position. In addition, since the operating element 40 and the return spring 44 are arranged in parallel, the switch device can be miniaturized in the height direction. On the other hand, when the switch device is viewed from the moving direction of the operating element 40 (refer to FIG. 3(A)), the return spring 44 is provided in the normal operation when the operating element 40 is operated against the force of the return spring 44 Position Pc (the normal position where force is applied to the operating member 40 from the outside when the operating member 40 is moved downwards. Also refer to Fig. 2(B)) offset position. Therefore, during the operation of the switch device, there is a deviation between the operating position at this time and the point of application of the return spring 44 of the opposing operating member 40. For this reason, the operating member 40 is likely to tilt.

In this embodiment, the return spring 44 is a compression spring. Since the return spring 44 is arranged on the side of the back surface 40b of the operating member 40, it is easy for the operating member 40 to tilt its upper part from the inner surface 101b of the device box 1 ( Tilt to the front). In other words, when viewed from the moving direction of the operating element 40, it is easy to act on the operating element 40 in the direction along the straight line passing through the position of the return spring 44 and the normal operating position Pc (in this embodiment, from the return spring The position of 44 faces the direction of the normal operation position Pc) to tilt the force of the operation member 40. Moreover, if the operating member 40 is tilted, a part of the operating member 40 will easily touch the inner surface 101b of the device box 1. Therefore, if the operating member 40 is moved up and down in this state, the operating member 40 will rub against the inner surface 101b of the device case 1. For this reason, the operating member 40 or the device case 1 may wear. In addition, if abrasion powder (resin chips, etc.) is generated due to abrasion of the operating element 40 or the device box 1, the abrasion powder adheres to the contact (fixed contact or movable contact) of the switch device, resulting in poor conduction of the contact. The fear.

Therefore, in this embodiment, as a tilt suppression structure for suppressing the tilt of the operating element 40, the following structure is constructed in the switch device (see FIG. 3(B)). That is, on the side where the position of the return spring 44 is the same with respect to the operating element 40 (ie, the back surface 40b side of the operating element 40), the operating element 40 is provided from the left side surface 40c and the right side surface of the operating element 40 A pair of left and right flange portions 45A and 45B projected by 40d is provided with a holding portion 104 for holding the pair of left and right flange portions 45A and 45B from both sides on the inner surface 101b of the device box 1. In other words, in the inner surface 101b of the device box 1, the holding portion 104 is provided at a position where a straight line passing through the return spring 44 and the normal operating position Pc when viewed from the moving direction of the operating member 40 intersect.

Specifically, the flange portions 45A and 45B are formed in such a way that their back surfaces and the back surface 40b of the operating member 40 are aligned on the same plane. In addition, the holding portion 104 is configured to not hinder the sliding of the flange portions 45A and 45B in the vertical direction when holding the flange portions 45A and 45B, and to allow the back surface 40b of the operating member 40 to contact or approach the device box 1.内面101b, and maintain this state. In this embodiment, the holding portion 104 has a pair of left and right guide grooves 104A and 104B, and flange portions 45A and 45B are respectively fitted into the guide grooves 104A and 104B, whereby the flange portions 45A and 45B are held by The part 104 is kept slidably.

According to this inclination suppression structure, the return spring 44 is provided at a position shifted from the normal operating position Pc. By this, even when the force to tilt the operating element 40 acts on the operating element 40, due to the left and right pair of protrusions The edge portions 45A and 45B are always held by the holding portion 104. Therefore, by this holding, it is suppressed that the operating member 40 is inclined and separated from the inner surface 101b of the device box 1. As a result, it is difficult to cause abrasion of the operating member 40, the device case 1, and the like, and therefore, the generation of abrasion powder is suppressed, and the conduction failure of the contact is unlikely to occur.

In addition, in such a configuration, in order to effectively suppress the tilt of the operating element 40, when the operating element 40 is tilted, the distance separated from the inner surface 101b of the device box 1 may be the largest upper part, and the holding part 104 Keep. For example, the holding portion 104 is provided at at least an upper portion of the inner surface 101b of the device box 1. In addition, FIG. 2(A) shows a case where the holding portion 104 is provided at a relatively upper position in the inner surface 101 b of the device box 1.

In this way, according to the switch device of this embodiment, the tilt of the operating member 40 can be suppressed.

Furthermore, it is preferable that in the switch device having the above-mentioned tilt suppression structure, a pair of left and right flange portions 45A and 45B are provided on at least the movable contacts 42A and 42B of the left side 40c and the right side 40d of the operating member 40 Opposite position. More preferably, in the operating member 40 and the movable contacts 42A and 42B, regardless of the position in their movable range, the flange portions 45A and 45B, and the flange portions 45A and 45B must be connected to the movable contact 42A. The way that and 42B face each other is provided on the left side surface 40c and the right side surface 40d in consideration of their position or length (refer to FIG. 2(A)).

According to this configuration, the insulation distance between the return spring 44 and the conductive member 401 (movable contacts 42A and 42B) can be made according to the amount of the left and right flanges 45A and 45B protruding from the left side 40c and the right side 40d. Become larger (refer to Figure 3(B)). Here, the insulation distance refers to the length of the shortest path Ri from the conductive member 401 to the return spring 44 bypassing the insulating member, that is, the operating element 40. In this embodiment, the shortest path Ri is through the operating element 40 The path from the return spring 44 to the conductive member 401 from the back surface 40b, the left side surface 40c, or the right side surface 40d.

[2] Modifications [2-1] The first modification Fig. 4 is a cross-sectional view of the switch device of the first modification, taken from the same line as the IIB-IIB line of Fig. 1(B). In the switch device of FIG. 4, the operating element 40 and the return spring 44 are arranged in series, whereby the return spring 44 is set to the same position as the normal operation position Pc. According to such a configuration, as long as the normal operation position Pc is pressed during the operation of the switch device, the action point of the return spring 44 of the opposing operating member 40 and the operating position coincide with each other. Therefore, it is difficult to tilt the operating member 40. On the other hand, even with such a switch device, as shown in FIG. 4, when a position shifted from the normal operation position Pc (operation position Pd. For example, the edge of the operation member 40, etc.) is pressed, it is relatively The operating point of the return spring 44 of the operating member 40 is deviated from the operating position. This is the reason, and the operating member 40 may tilt.

Therefore, even in the switch device of FIG. 4, it is preferable to provide the tilt suppressing structure described in the above embodiment, so that the tilt of the operating member 40 can be suppressed.

[2-2] Second modification The above-mentioned switch device can also be modified into a switch device constructed by overlapping two upper and lower stages of the same configuration. Fig. 5 shows an example of such a switch device as a second modification, and is a cross-sectional view taken along the same line as the IIA-IIA line in Fig. 1(B). In addition, FIG. 6 is a cross-sectional view of the switch device of the second modification, taken from the same line as the IIB-IIB line in FIG. 1(B). Figures 5 and 6 show the switchgear shown in Figs. 2(A) and 2(B) as the first stage, and the switchgear of the second stage is formed below it.

Specifically, the device box 1 shown in Figs. 2(A) and 2(B) is taken as the first section 131, from its bottom surface 131a (corresponding to the bottom surface of the device box 1 shown in Fig. 2(A) The area between the left and right wire insertion holes 11a and 11b in 1a) expands the portion 132 of the second stage downward. In addition, on the bottom surface 132a of the portion 132 of the second stage, there are provided wire insertion holes 14a and 14b (refer to Figure 5).

In addition, even in the portion 132 of the second stage, it is the same as the portion 131 of the first stage, corresponding to the left and right wire insertion holes 14a and 14b, respectively, and terminal units 2A and 2B that are push-in mechanisms are provided (see FIG. 5 ).

In addition, the switch mechanism 4 is configured such that the electrical short-circuit and disconnection between the terminal units 2A and 2B in the part 132 of the second stage (that is, the fixed contacts 41A and 41B in the part 132 of the second stage are connected to The contact and separation of the movable contacts 42A and 42B), the electrical short-circuit and disconnection between the terminal units 2A and 2B in the part 131 of the first stage, and the switching in conjunction with the up and down movement of one operating element 40 ( Refer to Figure 5).

Specifically, in the device case 1, the space 10c expands downward from the first-stage portion 131 to the second-stage portion 132 (refer to FIGS. 5 and 6). In addition, the operating member 40 and the return spring 44 also extend downward in the space 10c to the portion 132 of the second stage. Furthermore, in the operating member 40, each of the first-stage part 131 and the second-stage part 132 is provided with movable contacts 42A and 42B, and a bolt mechanism that enables the relative up and down movement of the conductive member 401 supporting them is provided .

In such a two-stage switchgear, in the space 10c of the device box 1, the fixed contacts 41A and 41B and the movable contacts 42A and 42B of the part 131 of the first stage are fixed to the part 132 of the second stage The contact points 41A and 41B and the movable contact points 42A and 42B are provided at positions offset from each other in the moving direction of the operating member 40. In addition, the operating element 40 is used to move both the movable contacts 42A and 42B of the part 131 of the first stage and the movable contacts 42A and 42B of the part 132 of the second stage.

In such a configuration, it is preferable that the pair of left and right flange portions 45A and 45B are provided on the left side surface 40c and the right side surface 40d of the operating member 40, and are connected to at least the first-stage portion 131. The positions where the points 42A and 42B oppose, and the positions where the movable contacts 42A and 42B of the part 132 of the second stage oppose. More preferably, the movable contacts 42A and 42B of the portion 131 of the first stage, and the movable contacts 42A and 42B of the portion 132 of the second stage of the operating member 40, regardless of the position within their movable range , The flange portions 45A and 45B, the flange portions 45A and 45B must be paired with either one of the movable contacts 42A and 42B of the section 131 of the first stage and the movable contacts 42A and 42B of the section 132 of the second stage In the way of orientation, they are provided on the left side surface 40c and the right side surface 40d in consideration of their positions, lengths, etc. (refer to FIG. 2(A)).

As an example, in the switch device of FIG. 5, the flange portions 45A and 45B extend continuously downward from the position opposed to the movable contacts 42A and 42B of the portion 131 of the first stage to the portion of the second stage. 132's movable contacts 42A and 42B oppose the position.

According to this configuration, the return spring 44 can be connected to the conductive member 401 (movable contact 42A and movable contact 42A and 42B) The insulation distance between the larger, 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. According to this, it is easy to prevent the conductive member 401 of the portion 131 of the first stage and the conductive member 401 of the portion 132 of the second stage from being electrically short-circuited via the return spring 44.

[2-3] Other modified examples In the terminal unit 2A, if it is capable of forming a firm connection state between the wire W1 and the terminal 21A, it is not limited to a push-in mechanism, and a screw mechanism that uses a screw to form a firm connection state between the wire W1 and the terminal 21A can also be used. . The same applies to the terminal unit 2B.

In the switch device of the above-mentioned embodiment (Figure 2(A)), the movable contacts 42A and 42B are not limited to the normal normally open contacts, and may be constructed as normally open contacts that are turned on earlier (more common normally open contacts). It can also be configured as a normally closed contact. In addition, in the switch device of the first modification (FIG. 5), at least one of the section 131 of the first stage and the section 132 of the second stage is not limited to the normal normally open contact, and may be configured to be early The normally open contact that is connected can also be constructed as a normally closed contact.

In the above-mentioned switch device, the return spring 44 may also be a tension spring, a leaf spring, or the like. When a tension spring is used as the return spring 44, the inclination direction of the operating member 40 is opposite to the case when a compression spring is used. In this case, the inclination suppression structure constituted by the pair of left and right flange portions 45A and 45B and the holding portion 104 may also be provided on the side opposite to the position of the return spring 44 with respect to the operating member 40 (that is, the operating Front 40a side of piece 40). In addition, the tilt suppression structure may be provided on both the same side and the opposite side of the position of the return spring 44 with respect to the operating member 40.

In the above-mentioned switch device, the tilt suppression structure is not limited to the one that uses the holding portion 104 to hold the pair of left and right flange portions 45A and 45B.
