The connector removal tool 1 according to the present invention mainly includes a member composed of a main body member 12 and a side wall member 14, a connector attachment member 40, and a pressing screw 20. The connector removal tool 1 has a length of about 95 mm, a width of about 50 to 60 mm, and a height of about 65 to 85 mm so as to correspond to the maximum number of cores of the connector 60.
Hereinafter, each component will be described. The components described below are made of metal, and steel and stainless steel (SUS) are often used in consideration of strength, workability, etc., but if the roles described below are satisfied, It is not limited to these.
[0013]
First, the connector mounting member 40 will be described. The connector mounting member is substantially U-shaped as shown in FIGS. 2 and 3, and is attached to the connector 60 fixed to the board 80, and is provided with a fitting groove 46 in which the connector 60 is mounted. ing. On the upper surface side of the connector mounting member 40, a female screw portion 42 to be screwed with a pressing screw 20 described later is provided so as to penetrate into the fitting groove 46.
A plurality of screws 44 are screwed onto one of the side walls so as to protrude into the fitting groove 46, and the number of screws 44 is appropriately designed according to the size of the connector 60. It is better to provide at least one protrusion 48 on the side of the insertion groove 46 on the other side wall. The contact body 66 and the connector 68 of the connector 60 can be surely eaten from the flat surface.
In consideration of stability when the connector 60 is mounted, a protrusion (not shown) may be provided on the side of the insertion groove 46 on the side of the side wall where the screw 44 is screwed. In the case where the protrusion is provided, it is desirable that the connector mounting member 40 be divided and temporarily fixed in consideration of the mountability of the connector 60 and fixed after the connector 60 is mounted.
When the protrusions 48 and the protrusions are provided, the connector mounting member is preferably a split structure rather than an integral structure.
The size of the connector mounting member 40 is approximately 50 mm in length and approximately the same as the length of the connector 60, that is, it is appropriately designed according to the number of cores of the connector 60.
[0014]
Next, the member 10 will be described. As shown in FIG. 2, the member 10 includes a substantially L-shaped main body member 12 and two substantially L-shaped side wall members 14. The main body member 12 and the two side wall members 14 form an insertion space 32 in which the connector mounting member 40 is mounted. In consideration of workability, the main body member 12 has a split structure in the present embodiment, and is formed into a substantially L shape by combining two plate-like pieces. On the upper surface side of the main body member 12, a through hole in which a later-described pressing screw 20 is mounted at a position corresponding to the female screw portion of the connector mounting member 40 and the two side wall members 14 are fixed with bolts 16. A mounting hole 18 is provided. The mounting hole 18 may be provided on the side surface instead of the upper surface. The shape of the mounting hole 18 is an ellipse (long hole) so that the number of cores of the connector 60 can be accommodated. The reason why the shape of the connector mounting member 40 is substantially U- shaped is to prevent the connector 60 from coming into contact with any part other than the surface B72 of the connector 60 when the connector 60 is removed from the board 80. Note that, when the pressing screw 20 is tightened, the connector removal tool 1 itself may rotate if it is tightened.

By providing the handle, the connector removal tool 1 itself can be suppressed by hand when the pressing screw 20 is tightened.
[0015]
Next, the pressing screw 20 will be described.
The pressing screw 20 is fixed to the upper surface of the main body member 12 of the member 10 and is not moved so much in the vertical direction by a C-shaped retaining ring. The pressing screw 20 is for pressing the surface B72 of the connector 60 with the pressing surface 22 of the screw 20 when the pressing screw 20 is screwed to the connector mounting member 40. Therefore, the length of the male screw portion 24 of the pressing screw 20 is appropriately designed so that the pressing surface 22 of the screw 20 protrudes into the fitting groove 46 when the screw 20 is screwed to the connector mounting member 40.
Further, in order to make it easy to tighten the pressing screw 20, in this embodiment, a support column 28 that can be rotated about 180 degrees with respect to the fulcrum 26 is attached to the screw 20. By attaching such a column 28, the pressing screw 20 can be easily tightened.
[0016]
Finally, how to remove the connector 60 will be described.
First, the connector mounting member 40 is covered so that the connector 60 enters the fitting groove 46 of the connector mounting member 40. In the covered state, the screw 44 of the connector mounting member 40 is tightened to such an extent that the pressing surface A50 of the screw 44 bites into the surface A70 of the connector 60.
Second, the member 10 is placed in the insertion space 32 of the member 10 so that the connector mounting member 40 with the connector 60 attached is inserted.
Thirdly, when the pressing screw 20 is screwed onto the connector mounting member 40 and the pressing screw 20 is tightened in a state where the member 10 is covered, the connector mounting member 40 has an arrow “I” as shown in FIG. The pressing screw 20 protrudes into the fitting groove 46 of the connector mounting member 40 and presses the surface B72 of the connector 60 with the pressing surface 22 at a certain stage. When the connector 60 is pressed in this way, the side wall member 14 or the insertion piece of the member 10 is in contact with the board 80 or the surface B72 of the connector 60. Therefore, although the connector 60 is pressed, the arrow "A" direction As a result, the contact 64 is removed from the substrate 80 in the end.
[0017]
An insertion piece not shown will be described.
Although the connector 60 is mounted on the substrate 80 as described above, a plurality of connectors 60 are generally mounted without a gap. In such a case, when removing the connectors 60 on both sides, there is a gap between the substrate 80 and the side wall member 14 on one side, and the balance of the tool 1 is poor. The insertion piece is mounted under the convex portion 30 of the side wall member 14.
