DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector operating tool used for pulling out a cable connector from a pin header provided in a transmission device such as a computer main body.

[0002]

2. Description of the Related Art In a conventional connector operating tool, as shown in FIG. 10, a sheet metal pistol-shaped tool main body 50 in which a grip portion 50A that can be gripped by one hand is formed by bending is provided.
A work arm 51 having an attachment portion 51A detachably attached to the connector 2 of the cable 1 from the cable connection side is integrally formed, and the work arm 51 is connected to the connector 2 jacketed by the attachment portion 51A of the work arm 51. In combination, a pair of upper and lower locking members 52 for applying an operating force in the cable longitudinal direction to the connector 2 and an operation mechanism B for switching the both locking members 52 between the locked state and the unlocked state are provided. (For example, see Japanese Utility Model Publication No. Sho 56-42953).

The operating mechanism B includes a sliding member 53 that is reciprocally movable in the front-rear direction along a sliding guide plate portion 51a formed by bending the upper and lower sides of the working arm portion 51, and a sliding member 53. The trigger 5 includes a compression spring 54 for urging forward movement and a trigger 55 for moving the sliding member 53 rearward against the elastic urging force of the compression spring 54.
By the pulling operation of 5, a pair of upper and lower locking members 52 attached to the distal end of the sliding member 53 are switched from the unlocked state to the locked state.

The upper end of the trigger 55 is pivotally attached to the tool body 50 so as to be able to swing back and forth around a horizontal axis in the left-right direction, and a hand holding the grip portion 50A of the tool body 50 is provided. The trigger 55 is configured to be able to be pulled by a finger, and an upper and lower middle portion of the trigger 55 is pivotally connected to a rear end of the sliding member 53 via a connecting pin 56 so that the elasticity of the compression spring 54 can be restored. It is configured such that both locking members 52 are biased and held in the unlocked state by force.

Each of the locking members 52 is made of a band-shaped leaf spring material, and has a tip portion bent inwardly at a substantially right angle into a hook shape. It is mounted in a bent posture in which the front end is opened outward so that the facing distance increases as the distance between the ends increases.

[0006]

In this conventional connector operating tool, even when a large number of cables 1 are connected to the transmission device in a dense state, the mounting portion of the working arm portion 51 connected to the tool main body 50 is provided. The connector 51 to be operated can be jacketed from the cable connection side through a narrow space around the connector 2 of each cable 1, and the mounting portion 51 A of the working arm 51 is jacketed at a predetermined position of the connector 2. At this point, the trigger 55 is pulled to operate the locking body 52 in the unlocked state to switch to the locked state, so that the connector 2 of the other closely arranged cables 1 is not obstructed. There is an advantage that only the connector 2 to be operated can be reliably pulled out.

However, the connector 2 of each cable 1
Is dense and difficult to see, or when the illumination of the location of the transmission device is dark, the mounting portion 51A of the working arm portion 51 is easily caught many times before being put on the connector 2 to be operated. When the mounting portion 51A of the portion 51 is covered with the connector 2, a shadow is easily formed by the mounting portion 51A itself, and as a result, the engagement position between the pair of upper and lower locking members 52 and the locked portion 2a of the connector 2 Since it is difficult to confirm the relationship, the working arm 51 for the connector 2 to be operated is
It is easy to take time in the outer layer process of the mounting portion 51A.

In addition, in conjunction with the pulling operation of the trigger 55, the pair of upper and lower locking members 52 are elastically deformed from the upper and lower directions to the sides approaching each other while moving backward, and are switched to the locking state. It is necessary to check the positional relationship between the pair of upper and lower locking members 52 and the locked portion 2a of the connector 2 while looking in from the side. Since the projection 52 always projects forward from the tip of the sliding member 53, the sliding member 53 is easily deformed and damaged by a collision with the connector 2 or another object.

SUMMARY OF THE INVENTION The present invention has been made in view of the above situation, and its main problem is that even if the connectors of each cable are dense or the illumination of the transmission device is dark, It is an object of the present invention to provide a connector operating tool capable of efficiently and easily and reliably performing a detaching operation including pulling out, inserting, or both.
