Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a jig used to remove a casing that covers the outside of an electronic device or the like.

[0002]

[Prior art]

 BACKGROUND ART Conventionally, electronic devices such as portable personal computers have been covered with a resin housing. When repairing or repairing such equipment, it is necessary to remove the housing. Conventionally, when removing the housing, there is no jig for performing this, for example, a minus driver has been used.

In order to remove the housing using this driver, for example, a driver is used as follows. As shown in FIG. 9, the flat portion of the driver tip 91 is moved along the gap 81 where the butted portion of the housing 8 is abutted, and the tip is pushed into the gap 81. Then, the driver 9 is twisted to separate the butted portion of the housing 8. By performing such an operation, the fitting portion fixing the housing is released, and the housing is removed from the main body.

[0004]

[Problems to be solved by the invention]

 However, when removing the housing 8 using the driver 9, a large force is required when inserting the tip of the driver into the gap or when twisting, and the removal requires skill. In addition, during the removal work, the tip of the driver came off from the gap, causing troubles such as injury to the worker and damage to the housing. In addition, since the driver is made of metal harder than the housing, the housing is particularly likely to be damaged. Forcibly opening with a driver, the fitting portion of the housing is damaged or, as shown in FIG. 10, there is a problem that the rear portion 82 of the driver remains in the portion where the driver is inserted.

An object of the present invention is to provide a jig which can be easily removed without damaging a housing.

[0012]

[Embodiment of the invention]

 Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is an overall perspective view of the housing removal jig 1 of the present invention. The housing removal jig 1 has a plate-shaped main body 2 and an insertion portion 3 formed at a corner of the distal end of the main body 2.

The main body 2 is a plate made of resin, and has a rear end portion formed with a hole 21 for passing a string or the like. The main body 2 is formed in a rectangular shape as a whole, and has a size enough to fit in a hand. More specifically, when it is held in the hand, it can be easily held by the gripping force of the hand, and has a size such that the force for operating the insertion portion 3 can be easily transmitted from the hand.

[0014] Specifically, when the thickness is in the range of about 8 to 25 mm, the width is in the range of about 15 to 60 mm, and the length is in the range of about 70 to 130 mm, the size of the main body 2 is easy to grasp. Further, it is preferably within the above range from the convenience of carrying. The range of the size is changed according to the size and type of the device from which the housing is removed, and is not particularly limited to this range. The body 2 is chamfered at each corner to improve the feel when gripped by hand. In the present embodiment, the main body 2 itself constitutes a handle.

Next, the configuration of the insertion section 3 will be described. As shown in FIG. 1, the insertion section 3 is provided at a corner of the distal end of the main body 2. The insertion portion 3 is formed in a shape in which two side surfaces 32 and 33 connected to the peripheral side surface of the main body 2 intersect at an acute angle, in other words, a wedge shape. FIG. 2 is a partial enlarged side view of the jig 1 for removing the housing, showing the configuration of the insertion portion 3. As shown in FIG. 2, the side surface 32 is located on the same plane as the peripheral side surface 22 of the main body 2, and an inclined surface 321 is formed on the distal end side of the insertion portion 3. Due to the formation of the inclined surface 321, the tip of the insertion portion 3 becomes sharper, and it becomes easy to insert the insertion portion 3 into the gap at the butt portion of the housing. The side surface 33 is continuously connected to the peripheral side surface 23 on the distal end side of the main body 2. The side surface 33 is a concave surface, and the distance between the side surface 32 and the side surface 33 increases toward the proximal end of the insertion portion 3.

The insertion portion 3 having the above-described configuration has the concave side surface 33 and the inclined surface 321 formed at the end of the side surface 32 on the opposite side. The overall shape is a shape warped to one side surface 33 side.

The operation of the housing removal jig 1 having such a configuration will be described. FIG. 3 is a partial cross-sectional view of the notebook portable personal computer showing how to remove the case 4 of the present invention when removing the housing 4 of the notebook portable personal computer. First, an attachment structure between the housing 4 and the personal computer body 5 will be described. As shown in FIG. 3 (a), the housing 4 and the personal computer body 5 are fixed by a fitting structure provided mutually. This fitting structure has a plurality of fitting holes 51 arranged at predetermined intervals in the vicinity of the peripheral end side on the personal computer main body 5 side. FIG. 4 is a perspective view showing a configuration of the fitting hole 51 provided on the personal computer main body 5 side. As shown in FIG. 4, the fitting hole 51 is provided between a pair of convex portions 52, 53 erected on the substrate plane of the personal computer main body 5 and between the pair of convex portions 52, 53. And a projection 54, and a fitting hole 51 is formed between the projections 52 and 53.

On the other hand, on the inner side of the housing 4, a claw 41 is formed at a position corresponding to the fitting hole 51 in the vicinity of the peripheral end side. When the housing 4 is attached to the personal computer main body 5, the claws 41 are fitted into the fitting holes 51. Here, the tip of the insertion section 3 is pressed into the gap 6 between the butting portion of the housing 4 and the personal computer body 5. The tip of the insertion section 3 is sharply formed, so that when the insertion section 3 is pushed in, the insertion section 3 is easily cut between the end of the housing 4 and the personal computer body 5. In addition, since the main body 2 has such a size that it can be easily gripped, the force for pushing the insertion portion 3 can be easily applied.

As shown in FIG. 3B, while pushing the distal end of the insertion portion 3 in the distal direction (the direction of the arrow a in the figure), the main body 2 is Rotate in the opposite direction (direction of arrow b in the figure). As a result, the distal end of the insertion portion 3 exerts an action of pushing up the housing 4 while pulling the end of the housing 4 forward (in the direction of the arrow d in the figure). This function is more effectively exerted by rotating the main body 2 and further pushing the insertion portion 3 in the distal direction (the direction of arrow c in the figure). That is, by pushing in the tip direction (the direction of arrow c in the figure), the wedge shape of the insertion portion 3 further pushes the end of the housing 4 forward (in the direction of arrow d in the figure). Push the housing 4 upward (in the direction of arrow e in the figure). As described above, the claw 41 of the housing 4 is easily disengaged from the fitting hole 51 by the action of pushing the end of the housing 4 forward (in the direction of the arrow d in the figure), and the housing 4 is easily removed from the personal computer body 5. 4 can be easily removed.

The casing removal jig 1 of the present embodiment is made of resin and is therefore soft and less likely to damage the casing 4. In addition, since the surface is smooth and slippery, the insertion portion 3 easily slips into the gap 6 at the butt portion between the housing 4 and the personal computer main body 5, and the above-described action is more easily exerted.

The above operations are sequentially performed for each fitting portion (the position where the fitting hole 51 and the claw 41 are provided). At this time, the insertion portion 3 can be more easily removed by moving (sliding) to the next adjacent fitting portion while being inserted between the personal computer main body 5 and the housing 4.

When such an operation is performed by a driver as in the related art, the action of pushing the end of the housing 4 forward (in the direction of the arrow d in the figure) is not obtained, and the operation is performed upward (in the direction of the arrow e in the figure). Since only the pushing force acts, the claw 41 is hard to come off from the fitting hole 51, and it is not easy to remove the housing 4. In addition, it also causes damage to the fitting structure such as the claw 41 and the beam 54.

FIG. 5 is an overall perspective view showing another configuration of the handle portion 24. The operation of the jig 1 for removing the casing has been described with reference to FIG. 3. However, when the jig 1 is rotated around the insertion section 3, the main body 2 comes into contact with a plane or the like on which the casing 4 is installed. When a proper rotation cannot be obtained, the angle between the insertion portion 3 and the handle portion 24 is set to be large, as shown in the figure, so that a sufficient angle can be obtained.

The above embodiment has a configuration in which the side surface 33 of the insertion portion 3 is curved. However, as shown in FIG. 6, the side surface 33 is a flat surface 34 or is shown in FIG. Thus, it may be a collection of bent planes 35a, 35b, 35c. Alternatively, as shown in FIG. 8, the side surface 32 may be a convex curved surface, and the entire insertion portion 3 may be curved. Such an insertion portion 3 has a configuration in which the width gradually increases from the distal end to the proximal end, and a line l (or a wedge) that bisects the angle of the distal end of the wedge shape on a plane where the wedge shape appears. Any configuration may be used as long as the line (a line located equidistant from the two side surfaces 32 and 33 intersecting at an acute angle forming the shape) is curved (or bent).

[Effect of the invention]

 According to the first aspect of the present invention, by pushing the tip of the insertion portion into the butted portion of the housing, the insertion can be easily performed by the action of the wedge shape. And, since the one side surface of the two side surfaces constituting the wedge shape is concave as a whole, it becomes easy to rotate along the concave surface with the insertion portion pushed in, and the housing is moved from the inside to the outside. The force to remove the body is likely to occur. At the same time, when the insertion portion is further pushed in, the action of pushing up the casing and the action of pushing out the casing from the inside to the outside are simultaneously exhibited by the action based on the wedge shape that becomes wider toward the base end, and The fitting part can be easily removed.

According to the second aspect of the present invention, since the insertion portion has a curved (or bent) shape as a whole, the shape of the insertion portion in a state where the insertion portion is inserted into the butt portion of the housing. And the force to remove the housing from the inside to the outside is more likely to occur.

According to the third aspect of the present invention, the insertion portion is made of a synthetic resin, so that the insertion portion has appropriate strength and appropriate softness. The housing is not easily damaged.

According to the invention of claim 4, by providing the handle portion to be accommodated in the hand, it is easy to grasp with the hand, and the force applied to the insertion portion can be efficiently transmitted from the hand to the insertion portion. Can be.

According to the present invention, by forming the handle portion by bending it toward the concave side surface, the operation of rotating the main body and removing the housing becomes easier.
