Description

The technology disclosed herein belongs to the technical field related to relay removal tools.

Conventionally, tools have been known for removing a removable relay attached to a socket from the socket.

For example, Patent Document 1 discloses that a band-like material having spring properties is formed into a U-shape to form two opposing arm parts, and at the ends of both arm parts, protrusions that respectively protrude from two opposing side surfaces of the relay are disclosed. A relay extraction tool is disclosed in which a system inlet is fitted into a protrusion (protrusion), and the relay is pulled with the system inlet fitted into the convex part to remove the relay from the socket.

Further, Patent Document 2 discloses a pliers-type relay removal tool in which a buffer-cum-friction sheet is provided inside a holding part.

Incidentally, the socket is provided with a locking portion that locks the relay from the side in order to prevent the relay from coming off. If the locking part of the socket is locked from the side of the relay as described above, in the device described in Patent Document 1, the system inlet hole cannot be fitted into the relay, making it difficult to attach and detach the relay. Become. Further, in the device described in Patent Document 2, it is not possible to release the lock between the relay and the locking portion, which makes it difficult to attach and detach the relay.

The technology disclosed herein has been developed in view of this point, and its purpose is to easily remove a relay that is locked from the side to a locking part of a socket from the socket. Our goal is to provide a relay removal tool that can be used to remove relays.

In order to solve the above problems, the technology disclosed herein targets a relay removal tool that removes a relay attached to a socket from the socket by being locked from the side to the locking part of the socket. a pair of rods rotatably supported by a support shaft ; a pair of grips provided on the proximal end sides of the pair of rods and configured to move toward each other to open and close the rods; a pair of clamping arms that are provided on the distal end sides of the pair of rods and can be closed to approach each other and clamp the relay by closing the pair of gripping parts, and the distal end of each clamping arm is connected to the Each of the insertion expansion parts is inserted between the relay and the locking part to expand the gap between the relay and the locking part, and each of the insertion expansion parts is attached to the rod side. The relay has a wedge shape that is inclined outward, and the side surface of the relay has a protrusion that engages with the locking part of the socket, and each of the insertion extensions accommodates the protrusion of the relay. Each of the housings has a housing portion, and the housing portion is a groove portion that is recessed toward the rod side and has an open end.

According to this configuration, since the insertion extension part has a wedge shape, it can be easily inserted between the relay and the locking part. After inserting the insertion extension part, insert the clamping arm between the relay and the locking part to expand the gap between the relay and the locking part and tighten the connection between the relay and the locking part. The stopped state can be canceled. Then, by holding the relay with the holding arms and pulling it, the relay can be removed from the socket. Therefore, the relay can be easily removed from the socket.

Further, according to this configuration, since the insertion extension part has the accommodating part, even if the relay has a protrusion, the clamping arm can be inserted as deeply as possible between the relay and the locking part. . Thereby, the gap between the relay and the locking part can be widened as much as possible, and the removal of the relay from the socket can be made easier. In addition, by housing the protrusion in the accommodating part, it is possible to prevent the protrusion from getting caught in the locking part again when the relay is pulled out from the socket. This also makes it easier to remove the relay from the socket.

In the relay removal tool, each of the clamping arms may have a non-slip portion on its inner side.

According to this configuration, since the gripping arm is prevented from slipping when the relay is pulled out from the socket, it is possible to further facilitate the removal of the relay from the socket.

In the relay removal tool, the pair of clamping arms may be detachably attached to the pair of rods.

According to this configuration, the size of the clamping arm can be changed depending on the size of the socket, so it can be used for various relays.

In the relay removal tool, each of the clamping arms has a claw portion having the insertion extension portion at the tip, and the maximum thickness of the claw portion is greater than or equal to the thickness of the protrusion of the relay. It may be configured as follows.

As explained above, according to the technology disclosed herein, the gap between the relay and the locking section is expanded by inserting the clamping arm between the relay and the locking section using the insertion extension section. By doing so, the locked state between the relay and the locking portion can be released. Thereby, the relay that is laterally engaged with the engagement portion of the socket can be easily removed from the socket.

Hereinafter, exemplary embodiments will be described in detail based on the drawings.

FIG. 1 shows a relay removal tool 1 (hereinafter simply referred to as tool 1) according to the present embodiment. The tool 1 is a tool for pulling out a plug-in type relay 100 attached to a socket 110 provided in an automobile or the like from the socket 110.

In this embodiment, as shown in FIG. 4, the relay 100 has a box shape, and has protrusions 102 on each of two opposing sides. On the other hand, the socket 110 has a locking part 112 that is provided in a rectangular hole 111 and covers a part of the side surface of the relay 100. The relay 100 is in a state where the two protrusions 102 enter the holes 111 of the locking portion 112, thereby being locked to the locking portion 112. The tool 1 is thus used to remove the relay 100, which is laterally locked to the locking portion 112 of the socket 110, from the socket 110.

The tool 1 has a pair of rods 3 rotatably supported by a support shaft 2 (see FIG. 2). Each rod 3 has a boss part 31 which is disk-shaped and to which the support shaft 2 is attached, a connecting part 32 connected to a grip part 4 described later, and a connecting part 32 that is two-fold symmetrical about the support shaft 2. The mounting portions 33 are provided at the positions shown in FIG. As shown in FIG. 2, the connecting portion 32 extends from a portion of the circumferential direction of the boss portion 31 in the tangential direction of the boss portion 31. As shown in FIG. The attachment portion 33 extends from a position that is two-fold symmetrical to the connection portion 32 toward the opposite side from the connection portion 32 . In the following description, the connecting portion 32 side will be referred to as the proximal end side of the rod 3, and the mounting portion 33 side will be referred to as the distal end side of the rod.

A pair of grip portions 4 that are gripped by a user are provided on the proximal end sides of the pair of rods 3. Each grip part 4 is constructed integrally with each connection part 32, respectively. That is, each grip part 4 and each rod 3 are integrated. By opening and closing the grip portion 4, the pair of rods 3 are opened and closed (FIGS. 1 to 3 show a state closer to the closed side).

Each grip portion 4 has a substantially S-shape. Specifically, each gripping part 4 has a shape in which it curves and extends away from each other from the base end of the connecting part 32, curves slightly toward each other, and then curves away from each other again at the end. is doing. Each grip portion 4 is covered with a grip body 41 made of elastomer or the like.

A pair of clamping arms 5 capable of clamping the relay 100 are provided on the distal ends of the pair of rods 3. The gripping arm 5 is opened and closed via the rod 3 by opening and closing the gripping section 4 . Specifically, when the gripping portion 4 is closed, the gripping portions 4 are closed so as to approach each other, and when the gripping portion 4 is opened, the gripping portions 4 are opened so as to be separated from each other. The clamping arm 5 is adapted to clamp the relay 100 when closed.

Each clamping arm 5 includes an arm body 51, a claw portion 52 that is integrally constructed with the arm body 51 and actually grips the relay 100, and a connecting rod 53 that is integrally constructed with the arm body 51 and connected to the mounting portion 33. and respectively. As shown in FIG. 2, the claw portion 52 extends from the arm body 51 toward the distal end side, and the connecting rod 53 extends from the arm body 51 toward the opposite side from the claw portion 52.

Each clamping arm 5 is attached to the attachment portion 33 of each rod 3 by a connecting rod 53, respectively. Specifically, as shown in FIG. 2, each attachment portion 33 has an insertion hole 33a at its tip portion into which each connection rod 53 is inserted. Each attachment portion 33 has a screw hole 33b on its side, into which the potato screw 6 is fastened. In each clamping arm 5, after the connecting rod 53 is inserted into the insertion hole 33a of the mounting portion 33, the potato screw 6 is fastened to the screw hole 33b, and the connecting rod 53 is attached to the wall of the insertion hole 33a by the potato screw 6. It is attached to the attachment part 33 by being pressed. Conversely, when the potato screws 6 are loosened, each clamping arm 5 can be removed from the mounting portion 33.

The claw portion 52 of each clamping arm 5 has a flat plate shape, as shown in FIGS. 2 and 3. As shown in FIG. 7, the maximum thickness of the claw portion 52 is the same as or slightly larger than the amount of protrusion of the protrusion 102 of the relay 100. As shown in FIG. 2, when the side where the relay 100 is sandwiched is the inside, the inner surfaces of each claw part 52 are configured to be parallel to each other when the clamping arm 5 is slightly opened from the fully closed state. ing. Thereby, as shown in FIG. 7, the relay 100 can be appropriately held.

The tip of each claw portion 52 has a wedge shape that is inclined outward toward the rod 3 side. The angle of inclination of the outer surface of the tip with respect to the inner surface can be set depending on the height of the locking part 112 of the socket 110, and is set to, for example, 30 degrees to 45 degrees. The distal end of each claw portion 52 is inserted between the relay 100 and the locking portion 112 during the operation of removing the relay 100 from the socket 110, and is inserted into the gap between the relay 100 and the locking portion 112 to expand the gap between the relay 100 and the locking portion 112. This constitutes a built-in extension section 52a.

As shown in FIGS. 1 and 3, each insertion expansion portion 52a has a groove portion 52b recessed toward the rod 3 side. As will be described in detail later, this groove portion 52b constitutes an accommodating portion that accommodates the protrusion portion 102 of the relay 100. The groove width of the groove portion 52b is set to be 1.5 to 2.0 times the width of the protrusion 102 of the relay 100. Further, the depth of the groove portion 52b is large enough to accommodate the entire protrusion 102, and is either the same as the length of the insertion extension portion 52a or slightly shorter than the length of the insertion expansion portion 52a.

A non-slip portion 52c is formed on the inner side of each claw portion 52. The anti-slip portion 52c is formed by digging a plurality of grooves adjacent to each other so as to form a jagged shape. As shown in FIG. 2, the anti-slip portion 52c occupies approximately one third of the length of the claw portion 52. As shown in FIG. In this way, by forming the anti-slip portions 52c by digging the grooves, it is possible to prevent each claw portion 52 from expanding inward. Thereby, the entire inner portion of each claw portion 52 can be brought into contact with the side surface of the relay 100, and the relay 100 can be stably held.

Next, the process of removing the relay 100 attached to the socket 110 will be described with reference to FIGS. 4 to 6.

First, in the initial state, the relay 100 is inserted into the socket 110. At this time, the protruding portion 102 of the relay 100 is in a state of being inserted into the hole 111 provided in the locking portion 112 of the socket 110.

From the above-mentioned initial state, the inner surface of the claw portion 52 is brought into contact with the side surface of the relay 100, as shown in FIG. At this time, the inner surface of the claw portion 52 is parallel to the side surface of the relay 100.

Next, from the state shown in FIG. 4, the tool 1 is moved toward the socket 110 while aligning the claw portion 52 along the side surface of the relay 100. At this time, due to the wedge shape of the insertion extension part 52a, the insertion extension part 52a smoothly enters between the relay 100 and the locking part 112. Then, the claw portion 52 is inserted until the projection portion 102 is accommodated in the groove portion 52b. As a result, as shown in FIG. 5, the gap between the relay 100 and the locking part 112 is expanded by the claw part 52. As a result, the locked state between the protruding portion 102 and the locking portion 112 is released.

Then, from the state shown in FIG. 5, grasp the grip part 4 so as to slightly close it. Thereby, the relay 100 can be appropriately gripped by the claw portion 52. Then, pull the relay 100 to the side opposite to the socket 110. At this time, since the claw portion 52 is present between the relay 100 and the locking portion 112 while the projection portion 102 is accommodated in the groove portion 52b, the projection portion 102 is prevented from being caught in the locking portion 112. As a result, the relay 100 can be easily removed from the socket 110, as shown in FIG.

Therefore, in this embodiment, a pair of rods 3 are rotatably supported by the support shaft 2, and the rods 3 are provided at the proximal ends of the rods 3, and are moved close to each other to open and close the rods 3. It includes a pair of gripping parts 4 and a pair of clamping arms 5 which are provided on the distal end sides of the pair of rods 3 and can close to each other and grip the relay 100 by closing the pair of gripping parts 4. The distal end of the arm 5 has an insertion expansion part 52a that is inserted between the relay 100 and the locking part 112 to expand the gap between the relay 100 and the locking part 112. 52a has a wedge shape that is inclined outward toward the rod 3 side. Thereby, the insertion extension part 52a can be easily inserted between the relay 100 and the locking part 112. After inserting the insertion expansion part 52a, the claw part 52 is inserted between the relay 100 and the locking part 112 to expand the gap between the relay 100 and the locking part 112, and the relay 100 The locked state between the locking portion 112 and the locking portion 112 can be released. Then, the relay 100 can be removed from the socket 110 by gripping and pulling the relay 100 between the claw portions 52. Therefore, the relay 100 that is laterally locked to the locking portion 112 of the socket 110 can be easily removed from the socket 110.

Furthermore, in this embodiment, the side surface of the relay 100 has a protrusion 102 that engages with the locking part of the socket 110, and the insertion extension 52a has a groove 52b that accommodates the protrusion 102 of the relay 100. . As a result, since the insertion extension part 52a has the groove part 52b, even if the relay 100 has the protrusion part 102, the clamping arm 5 can be inserted as deeply as possible between the relay 100 and the locking part 112. I can do it. Thereby, the gap between the relay 100 and the locking part 112 can be widened as much as possible, and the removal of the relay 100 from the socket 110 can be made easier.

Furthermore, in this embodiment, the gripping arm 5 has a non-slip shape on its inner side. This prevents the gripping arm 5 from slipping when the relay 100 is pulled out from the socket 110. As a result, the relay 100 can be removed from the socket 110 even more easily.

Furthermore, in this embodiment, the clamping arm 5 is detachably attached to the pair of rods 3. Thereby, the size of the clamping arm 5 can be changed according to the size of the socket 110, so the tool 1 can be used for various relays 100.

The present invention is not limited to the embodiments described above, and substitutions may be made without departing from the scope of the claims.

For example, in the embodiment described above, the protrusion 102 was provided on the side surface of the relay 100, and the hole 111 that engaged with the protrusion 102 was provided in the locking part 112 of the socket 110. However, the present invention is not limited to this, and for example, a recess may be provided on the side surface of the relay 100, and a protrusion that engages with the recess may be provided on the locking portion 112 of the socket 110. Further, the locking portion 112 of the socket 110 may have a claw portion that is hooked on a part of the upper surface of the relay 100.

Further, in the embodiment described above, the anti-slip portion 52c was formed by digging a groove in the inner portion of each claw portion 52. However, the present invention is not limited to this, and by pasting a rubber material or the like on the inner side of each claw portion 52, the anti-slip portion 52c may be formed. At this time, in order to prevent each claw part 52 from partially expanding inward and reducing the contact area with the relay 100, the thinnest material is used as possible, or the entire inner part of each claw part 52 is It is preferable that it is pasted over the entire area.

Further, in the embodiment described above, the rod body 3 and the clamping arm 5 were constructed as separate bodies that can be attached and detached. However, the present invention is not limited to this, and the rod body 3 and the clamping arm 5 may be configured integrally.

The above-described embodiments are merely illustrative and should not be construed as limiting the scope of the present invention. The scope of the invention is defined by the claims, and all modifications and changes that come within the range of equivalents of the claims are intended to be within the scope of the invention.
