Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a tool for detaching and attaching a connector such as a set of connectors, and more particularly to a detachable tool that can be driven in both directions by the same operation.

[0002]

[Prior art]

 The connector used for connecting the cable has a structure in which the plug and the socket are firmly press-fitted so that they will not easily come off. Therefore, the attachment / detachment must be performed using a tool capable of exerting a great force by utilizing the principle of leverage and the like. In this case, if the dedicated tools are used separately for the removal operation and the wearing operation, the operability when performing both operations alternately and continuously is poor, so both operations can be performed by the same tool. Is desirable.

As a tool capable of performing both of the above operations, there is a utility model No. 63-106092 shown in FIG. 6 (application No. 61-199819) and a model No. 63-106093 shown in FIG. 7 (actual application). A detachable tool of Japanese Patent Application No. 61-199820) has been proposed. The detachment tool shown in FIG. 6 has a tool head 1 on which a pair of holders 4 and 5 for holding one of a plug 2 and a socket 3 are detachably held, and the tool head 1 has a hinge. By operating a pair of coupled levers 6, both holders 4 and 5 are separated and approached, and the connector 7 is connected and separated between them.

That is, the tool head 1 is provided with a stationary holder 4 in a fixed state and a movable holder 5 which is movable in a direction in which the stationary holder 4 faces the stationary holder 4. A rod 8 parallel to the stationary holder 4 is continuously provided so as to project from the tool head 1, and a pair of levers 6 are provided so as to be arranged on both sides of the projecting portion of the rod 8. 1, two ends of a pair of link mechanisms 10 and 11 formed by connecting a pair of links 9 are pin-connected to each other between the levers 6. These link mechanisms 10 and 11 are bent in mutually opposite directions so that the direction of the connecting portion between the links 9 is directed in both directions of the length direction of the rod 8, and the holes 12 formed in the connecting portion are The pin 13 is adapted to be inserted, while the rod 8 is provided with holes 14 at two positions spaced in the length direction.

Then, the hole 12 of one of the link mechanisms 10 and 11 and the hole 14 of the rod 8 are aligned with each other in accordance with the removal operation and the wearing operation, and the pin 13 is inserted so as to penetrate these holes 12 and 14. By inserting one of the link mechanisms 10 and 11 and the rod 8 via the pin 13, the driving force of the lever 6 can be transmitted to the rod 8. In FIG. 6, when the left side link mechanism 10 is connected to the rod 8, the wearing operation is performed, and when the right side link mechanism 11 is connected to the rod 8, the releasing operation is performed.

Further, in the detachable tool shown in FIG. 7, only one set of the link mechanism 15 is provided between the levers 6, and the tool head 16 has a common holder 17 in a fixed state and a common holder 17 by operating the lever 6. A holder 18 for wearing operation that is made to approach and a holder 19 for removing operation that is separated from the shared holder 17 are provided, and the holders are selectively used depending on the operation for wearing and the operation for removing.

[0007]

[Problems to be solved by the device]

 However, in the former detachable tool, when switching between the detaching operation and the attaching operation, it is necessary to pull out the pin 13 from one of the link mechanisms and insert it into the other link mechanism. , The work of inserting and removing the pin 13 is complicated, and the removed pin 13 may be lost. In addition, since the latter detaching tool does not require pin insertion / removal work, it has good operability, but it requires two sets of holders for attaching and detaching operations, which makes the tool head 16 larger. There's a problem.

The present invention eliminates the problems found in the above-mentioned tools, and is a novel detachable attachment tool capable of both detachment and attachment operations that achieves both improved operability and downsizing at the same time. The purpose is to provide.

[0009]

[Means for Solving the Problems]

 The detachable tool according to claim 1, wherein the tool head has a stationary holder in a fixed state that holds one of a pair of connectors in a detachable manner, and a movable holder that is movable along a direction facing the stationary holder. And a rod parallel to the facing direction is continuously provided in the movable holder in a state of protruding from the tool head, and a pair of levers is arranged so as to be arranged on both sides of the protruding portion of the rod. At least two sets of link mechanisms, which are installed in a hinged state on the tool head and have links connected between these levers, are pin-coupled to each other at intervals in the length direction of the rod. Insert a locking pin consisting of a large-diameter part and a small-diameter part in series at the connection part between the links so that it can move in the longitudinal direction of the pin, and insert the locking pin into the rod. In the length direction of the rod These guide holes are provided by linking a long hole that movably engages the small diameter part of the locking pin in the length direction of the rod and a large diameter part of the locking pin in the locked state. It is characterized in that it is composed of a fixing hole for making the driving force of the mechanism act on the rod.

Further, in the detaching tool according to the second aspect of the present invention, the link mechanism is one set, and the guide hole includes the elongated hole and the fixing holes provided at both ends of the elongated hole.

[0011]

[Action]

 The attachment / detachment tool according to claim 1 allows the driving force of the link mechanism to act on the rod by fitting the large diameter portion of the locking pin in any of the link mechanisms into the fixing hole of the rod. By inserting the small diameter portion of the stop pin into the elongated hole of the rod, the connection between the link mechanism and the rod can be released. Then, by selectively using both the link mechanisms, it is possible to perform the wearing operation and the removing operation. In this case, it is possible to connect and disconnect the link mechanism and the rod by simply sliding them without removing the locking pins, so that both locking pins can be attached and detached while attached to the link mechanism. It can be carried out. Further, since the head part has a structure in which the connector is attached / detached by a single holder, the structure is simple and compact.

According to the second aspect of the present invention, since the attachment / detachment tool has the fixing holes at both ends of the elongated hole which is the guide hole of the rod, the direction of the link mechanism is changed to connect the rod with the rod through one of the fixing holes. By tying, both attachment and detachment operations can be performed with a single link mechanism.

It is in a state of protruding from the rear end of 31. Reference numeral 59 indicates a sleeve into which the rod 34 is slidably inserted. The concave portion 43 of the tool head 31 is set to a size capable of separating the movable holder 33 from the stationary holder 32 to a position where the separated adapter 39 can be interposed between the holders 33 and 34. .

On the other hand, one end of the lever 35 is attached to the base end of the tool head 31 so as to be arranged on both sides of the projecting portion of the rod 34, so that they can rotate in the same plane. The link mechanisms 36 and 37 formed by connecting a pair of links 61 are arranged in the middle in the lengthwise direction, and two sets are arranged on each side of the rod 34, for a total of four sets.

The link mechanisms 36 and 37 are arranged at the same positions on the left and right sides of the rod 34, and are provided at intervals in the length direction of the rod 34. The levers 35 are pin-coupled so as to connect them to each other, and the levers 35 are urged in the opening direction by springs 63 provided on the pins 62 at the joints. Further, as shown in FIG. 1, the link mechanisms 36, 37 on the left and right sides of the rod 34 are bent in a dogleg shape in mutually opposite directions, and a hole 64 is formed in a bent portion at an intermediate point thereof. The locking pin 38 penetrates through the holes 64 of both link mechanisms 36 and 37 and connects the two sets of both link mechanisms 36 and 37 arranged at the same position on the left and right of the rod 34, respectively. It is inserted so that it can move in the length direction of the pin. In this embodiment, the link mechanism 36 that is convex toward the tool head 31 is called an inward link mechanism, and the link mechanism 37 that is convex toward the direction opposite to the tool head 31 is called an outward link mechanism. .

As shown in FIG. 3, the locking pin 38 has a small-diameter portion 72 slidably inserted into a cylindrical large-diameter portion 71 and a slotted groove formed in the large-diameter portion 71. The stopper pin 74 of the small-diameter portion 72 is engaged with 73 to prevent mutual disengagement, and flange portions 75 are formed at both ends. As shown in FIG. It is arranged on both sides of the mechanisms 36 and 37.

Then, the holders 32 and 33 are kept in a separated state, and the holders 32 and 33 hold the plug 23 and the socket 24 of the connector 21 in the separated state via the adapter 39 in a fixed state. Next, when both levers 35 are gripped and rotated in the direction indicated by the arrow (a) in FIG. 1, the rod 34 is pressed by the inward link mechanism 36 that is moved toward the tool head 31 side, and the rod ( As shown in (b), the movable holder 33 fixed to the tip of the rod 31 is driven toward the stationary head 32 by being driven in the direction of entering the tool head 31, and is pressed by both holders 32, 33. On the other hand, the plug 23 and the socket 24 are press-fitted to each other.

“Detachment” From the state shown in FIG. 1, the large diameter portion 71 of the engaging pin 38 on the tool head 31 side connecting the inward link mechanism 36 to the rod 34 is pulled to extend the engaging pin 38. By pulling out the large diameter portion 71 from the small diameter portion 72, the small diameter portion 72 of the locking pin 38 is engaged with the elongated hole 77 of the guide hole 76, so that the inward link mechanism 36 and the rod 34 are connected. The outward link mechanism 37 is connected to the rod 34 by releasing the connection and positioning and pushing the locking pin 38 on the rear end side of the rod 34 into the fixing hole 78 of the guide hole 76. Then, the holders 32 and 33 are kept close to each other, and the connected connector 21 is interposed between the notches 40 of the adapter 39. Next, when both levers 35 are gripped and rotated in the arrow (a) direction, the rod 34 is pushed by the outward link mechanism 37 that is moved toward the rear end direction of the rod 34, and the rod 34 is opposite to the arrow (b). Direction, that is, the direction in which the movable holder 33 integral with the rod 34 is separated from the stationary holder 32 by being driven in the direction in which the plug head 23 comes out of the tool head 31, the plug 23 of the connector 21 and the socket 24 are separated.

That is, the detaching tool makes a strong force to act on the rod 34 by the link mechanisms 36 and 37 to facilitate the detaching work of the connector 21 which is firmly connected, and at the same time, to set the two link mechanisms. By selectively using 36 and 37, the release operation and the wearing operation can be switched. Furthermore, since the two sets of link mechanisms 36 and 37 are in the opposite directions, driving in both the removal operation and the wearing operation can be performed. It can be performed by the same operation of gripping the lever 35.

In both of these operations, the connector attachment / detachment work is performed by one set of holders 32 and 33 without providing two sets of holders as in the conventional example of FIG. The structure of is also simple and small.

Further, in the above-described embodiment, two sets of the link mechanisms 36 and 37 are provided for the detaching operation and the wearing operation.

One hole 82 is provided, and fixing holes 78 are arranged at both ends of the elongated hole 77, and one of the fixing holes 78 can be selected by changing the direction of the bent portion of the link mechanism according to the detaching operation and the attaching operation. It may be configured to be locked automatically. With such a structure, both the attaching operation and the releasing operation can be performed by the single link mechanism, and the structure is further simplified.

Further, in the above-described embodiment, the stationary holder is fixed to the tip of the tool head and the movable holder is provided on the base end side. However, the holder may be arranged in the opposite manner. When the rod is driven in the direction of the tip of the tool head, it is released and when it is driven in the direction of pulling out, it is attached. Further, the detaching tool of the present invention can be applied to similar male and female connectors other than the connector, and the holder for holding these connectors can be connected at least along the facing direction of the holder. Anything that can restrain the movement of the container can be used. The design of the structure of the locking portion can be changed.
