Abstract

PROBLEM TO BE SOLVED: To improve the workability when a crimped terminal is fixed while easily ensuring the conduction between the crimped terminal and an attachment object.SOLUTION: Since a fixture tool comprises a terminal temporary fixing part 2B which engages with a round crimped terminal 50 thereby preventing the round crimped terminal 50 from coming off from an insertion part 2, it is possible to temporarily fix the round crimped terminal 50 to the insertion part 2. Thus, the fixing work of the round crimped terminal is finished by inserting the insertion part 2 into a mounting hole with the round crimped terminal temporarily fixed. The terminal temporary fixing part 2B contacts with an inner peripheral surface of the mounting hole when being attached to an attachment object. Thus, it is possible to fix the insertion part 2 to the mounting hole while conduction is ensured between the round crimped terminal and the attachment object through the terminal temporary fixing part 2B. Therefore, the workability is improved when the round crimped terminal is fixed while the conduction is easily ensured between the round crimped terminal and the attachment object.

  The attachment object 60 is an aluminum member on which an insulating film such as an oxide film is formed. And the attachment object 60 is provided with the attachment hole 61 penetrated from the front surface to the back surface, as shown in FIG.

  The attachment hole 61 is a hole formed with a cutting tool such as a drill after the insulating film is formed on the attachment object 60. For this reason, the inner peripheral surface of the attachment hole 61 is in a state where the base material (aluminum in the present embodiment) of the attachment object 60 is exposed.

The round crimp terminal 50 is an annular flat plate having an opening 51 for fixing. The round crimp terminal 50 may be connected to a lead wire or a ground (not shown) by a fixing method such as soldering or caulking. Electric wires such as wires are fixed.

1. Configuration / Shape of Mounting Tool As shown in FIG. 8 or FIG. 9, the mounting tool 1 includes an insertion portion 2, an outrigger portion 3, a terminal pressing portion 4, and the like. And the insertion part 2-the press part 4 grade | etc., Are integrally formed by giving a press work to one metal plate. In addition, the fixture 1 which concerns on this embodiment is metal which has elasticity (spring property), such as stainless steel.

<Insertion section>
As shown in FIG. 15, the insertion part 2 is a part that penetrates the opening 51 and reaches the attachment hole 61 in a state of being attached to the attachment object 60. As shown in FIG. 10, the insertion portion 2 includes a pair of plate surfaces 2 </ b> A that face each other and a connection portion 2 </ b> D that connects the pair of plate surfaces 2 </ b> A.

  The connecting portion 2D is a portion that is provided at the front end of the insertion portion 2 in the insertion direction and is bent in a U shape or a V shape. The pair of plate surfaces 2A and the connecting portion 2D are integrally formed by subjecting one metal plate material to plastic working such as press forming.

  For this reason, the insertion part 2 can be elastically deformed so that a pair of plate surface 2A formed in strip | belt board shape may adjoin or space apart. The pair of plate surfaces 2 </ b> A are elastically deformed so as to be close to each other when the fixture 1 is inserted into the mounting hole 61. For this reason, when the fixture 1 is inserted into the mounting hole 61, the pair of plate surfaces 2 </ b> A are brought into pressure contact with the inner peripheral surface of the mounting hole 61 by the elastic force generated in the insertion portion 2.

  Moreover, as shown in FIG. 9, the terminal temporary fix | stop part 2B is provided in the width direction both ends of each board surface 2A. As shown in FIG. 2, these four terminal temporary fixing portions 2B are protrusions protruding outward from the width direction end of the plate surface 2A, and from the end toward the retreating side in the insertion direction. This is a triangular protrusion whose protrusion dimension gradually increases. The width direction is a direction substantially parallel to the plate surface 2A and orthogonal to the insertion direction.

  For this reason, when the insertion portion 2 is inserted into the opening 51 of the round crimp terminal 50, the pair of plate surfaces 2A are pressed against the inner peripheral surface of the opening 51, and each terminal temporary fixing portion 2B and the round crimp are connected. The terminal 50 can be engaged. When any of the terminal temporary fixing portions 2B is engaged with the round crimp terminal 50, the round crimp terminal 50 is prevented from dropping from the insertion portion 2.

  When the fixture 1 is inserted into the mounting hole 61, as shown in FIG. 16, at least one of the terminal temporary fixing portions 2B protrudes from the insertion portion 2 toward the inner peripheral surface 61A of the mounting hole 61. Thus, the inner peripheral surface 61A is brought into contact.

  Further, as shown in FIG. 14, each of the pair of plate surfaces 2 </ b> A is provided with an engagement protrusion 2 </ b> C that engages with the attachment target body 60 in a state where the fixture 1 is attached to the attachment target body 60. . These engagement protrusions 2C are integrally formed with the insertion portion 2 by cutting and raising a part of the plate surface 2A.

  That is, each engagement protrusion 2C is a band spring-like protrusion, and is connected to the plate surface 2A on the advance side in the insertion direction. And each engagement protrusion 2C is separated from 2 A of plate surfaces, so that it goes to the insertion direction retreat side.

  For this reason, when the insertion portion 2 is inserted into the mounting hole 61, each engagement projection 2C is elastically deformed so as to be close to each plate surface 2A, and when the insertion is completed, each engagement projection 2C is restored. As shown in FIG. 15, the engagement protrusions 2 </ b> C engage with each other so that the tip side contacts the back surface of the attachment target body 60.

<Outrigger part>
As shown in FIG. 13, the outrigger portion 3 is provided on the retracting side of the insertion portion 2 in the insertion direction of the fixture 1. And the outrigger part 3 contacts the surface of the attachment target body 60 in the state in which the fixture 1 was attached to the attachment target body 60.

  That is, as shown in FIG. 15, a portion of each plate surface 2 </ b> A connected to the retracted side in the insertion direction is bent so as to extend outward of the attachment hole 61. The bent portion extends to the outer side of the round crimp terminal 50 and comes into contact with the surface of the attachment object 60 to constitute the outrigger portion 3.

  Further, the portion A on the distal end side in the extending direction of the outrigger portion 3 is curved so that the center of curvature exists on the attachment target body 60 side from the plate surface of the portion A at least in a state of being attached to the attachment target body 60. .

  That is, the outrigger portion 3 has a flat portion 3A, a tip bending portion 3B, and the like. The flat portion 3 </ b> A is a portion that extends outward from the curved portion B that forms the boundary between the insertion portion 2 and the outrigger portion 3 in parallel with the round crimp terminal 50. The tip bending portion 3B is a portion extending from the flat portion 3A to the tip, and is a portion extending toward the surface of the attachment target body 60 so as to protrude at an acute angle with respect to the surface.

  Further, a portion of the tip bending portion 3B that contacts the surface of the attachment target body 60 is provided with a square edge portion 3C. The edge portion 3 </ b> C directly uses the corner generated on the end surface of the plate material when the plate material constituting the fixture 1 is cut and formed. For this reason, the edge portion 3C has a shape similar to a corner generated on the end face of the plate material when the metal plate is cut by shearing, for example.

  When the fixture 1 is inserted into the attachment hole 61 and each engagement protrusion 2C is engaged with the attachment target body 60, the radius of curvature of the distal bending portion 3B is attached to the attachment target body 60 by the attachment tool 1. It will be in the state which elastically deformed so that it might become larger than before.

  For this reason, in a state where the engagement protrusions 2C are engaged with the attachment target body 60 and the attachment of the fixture 1 is completed, the elastic force accompanying the elastic deformation of the tip bending portion 3B acts on the edge portion 3C. The contact surface pressure between the part 3C and the attachment target body 60 becomes very large.

<Terminal pressing part>
The terminal pressing portion 4 is a portion that is in pressure contact with the round crimp terminal 50. In this embodiment, the terminal pressing portion 4 is press-contacted to the round crimp terminal 50 to ensure the conduction between the round crimp terminal 50 and the fixture 1.

  Further, as shown in FIG. 13, two terminal pressing portions 4 are provided on the opposite side of each edge portion 3 </ b> C across the curved portion B in a direction parallel to the extending direction of the outrigger portion 3. That is, each terminal pressing part 4 is provided on the opposite side of the connecting part 2D with respect to the insertion part 2, as shown in FIG.

  Each terminal pressing portion 4 extends from one plate surface side of the pair of plate surfaces 2A to the other plate surface side. Specifically, the terminal pressing portion 4A on the left side of the drawing with respect to the insertion portion 2 extends from the left side of the drawing to the right side of the drawing. On the other hand, the terminal pressing portion 4B on the right side of the drawing with respect to the insertion portion 2 extends from the right side of the drawing to the left side of the drawing.

  As shown in FIG. 16, each of the four terminal pressing portions 4 extends from the curved portion B in the direction opposite to the extending direction of the outrigger portion 3 at a position shifted in the width direction from the plate surface 2A so as to avoid the insertion portion 2. Are in contact with the round crimp terminal 50.

  That is, each terminal pressing portion 4 extends toward the opposite side to each edge portion 3C so as to branch from the flat portion 3A. As shown in FIG. 15, a curved portion 41 that extends and curves so as to project into the round crimp terminal 50 is provided on the distal end side in the extending direction of each terminal pressing portion 4. For this reason, the extending direction front end side of each terminal pressing portion 4, that is, the bending portion 41 is also curved so that the center of curvature exists on the attachment target body 60 side, similarly to the outrigger portion 3.

  When the fixture 1 is inserted into the attachment hole 61 and each engagement protrusion 2C is engaged with the attachment target body 60, the curvature radius of the distal end side in the extending direction of each terminal pressing portion 4 is determined by the fixture 1. It will be in the state elastically deformed so that it might become large compared with before being attached to the attachment object 60.

  For this reason, in the state where each engagement protrusion 2C engages with the attachment target body 60 and the attachment of the fixture 1 is completed, the elastic force accompanying the elastic deformation on the distal end side in the extending direction of each terminal pressing portion 4 is Since it acts on the tip corner of the portion 4, the contact surface pressure between each terminal pressing portion 4 and the round crimp terminal 50 becomes very large.

2. Installation work of fixture (how to use fixture)
First, as shown in FIG. 10, the insertion portion 2 is inserted into the opening 51 until the round crimp terminal 50 is positioned between the bending portion B and the terminal temporary fixing portion 2B. As a result, the round crimp terminal 50 can be engaged with the terminal temporary fixing portion 2 </ b> B, and the round crimp terminal 50 is temporarily fixed to the fixture 1.

  Next, as shown in FIG. 15, the insertion portion 2 of the fixture 1 to which the round crimp terminal 50 is temporarily fixed is inserted into the attachment hole 61 of the attachment target body 60, and each engagement protrusion 2 </ b> C is inserted into the attachment target body. 60 is engaged. Accordingly, the round crimp terminal 50 is sandwiched between the fixture 1 and the attachment target body 60, and the round crimp terminal 50 is fixed to the attachment target body 60.

In addition, since the terminal temporary fixing portion 2 </ b> B and the edge portion 3 </ b> C are in a state where they can be electrically connected to the attachment target body 60, the round crimp terminal 50 can be electrically connected to the attachment target body 60 via the attachment tool 1.
3. Features of the fixture according to the present embodiment In the present embodiment, since the terminal temporary fixing portion 2 </ b> B is provided, the round crimp terminal 50 can be temporarily fixed to the insertion portion 2. For this reason, the fixing operation of the round crimp terminal 50 is completed by inserting the insertion portion 2 into the mounting hole 61 in the temporarily fixed state.

  Moreover, since the terminal temporary fix | stop part 2B contacts the inner peripheral surface 61A of the attachment hole 61 in the state attached to the attachment target body 60, it is connected with the attachment target body 60 via the terminal temporary fix part 2B. The insertion portion 2 can be fixed to the mounting hole 61 while ensuring.

As described above, according to the present embodiment, it is possible to improve workability when fixing the round crimp terminal 50 while easily ensuring the conduction between the round crimp terminal 50 and the attachment target body 60. .
By the way, in this embodiment, the insertion part 2 is bent in U shape or V shape so that the distance between 2 A of a pair of board surfaces may become so large that it goes to the insertion direction backward side. For this reason, if the insertion part 2 is inserted deeply into the opening 51 until the round crimp terminal 50 comes into contact with the terminal pressing part 4, the terminal temporary fixing part 2B and the round crimp terminal 50 do not engage with each other. The pair of plate surfaces 2A may be in pressure contact with the inner peripheral surface of the opening 51.

  In the above case, the friction generated at the contact portion between the pair of plate surfaces 2A and the inner peripheral surface of the opening 51 even if the terminal temporary fixing portion 2B and the round crimp terminal 50 are not engaged. The force prevents the round crimp terminal 50 from falling off the insertion portion 2.

  However, if the operator accidentally touches the round crimp terminal 50 before inserting the insertion portion 2 into the mounting hole 61, the round crimp terminal 50 is inserted by the impact force at that time only with the above frictional force. The possibility of falling off from the part 2 is very high.

  On the other hand, in this embodiment, since the terminal temporary fixing portion 2B is provided, even if the impact force acts on the round crimping terminal 50, the terminal temporary fixing portion 2B is provided with the round crimping terminal 50. Always engage with. For this reason, it is possible to reliably prevent the round crimp terminal 50 from falling off the insertion portion 2, so that the mounting operation can be performed in a state where the round crimp terminal 50 is temporarily fixed to the fixture 1.

  Moreover, in this embodiment, when attaching a fixture to the attachment target body 60, since the square edge part 3C and the surface of the attachment target body 60 inevitably rub, when attaching a fixture, the edge part 3C and The film in contact with the part is removed.

  Therefore, in addition to the terminal temporary fixing portion 2B, the continuity can be ensured also in the edge portion 3C, so that the continuity is reliably ensured between the round crimp terminal 50 and the mounting object 60 via the fixture 1. However, the round crimp terminal 50 can be easily fixed to the attachment object 60.

  Further, in the present embodiment, the engagement protrusion 2C can be easily displaced by the elastic deformation of the insertion portion 2, so that the workability when inserting the attachment tool 1, that is, the insertion portion 2 into the attachment hole 61, is improved. Can be improved.

  Moreover, in this embodiment, since the outrigger part 3 is curving so that a curvature center may exist in the attachment target body 60 side from the plate surface, it presses the edge part 3C strongly against the surface of the attachment target body 60. Therefore, the film can be removed reliably.

Other configurations are the same as those of the fixture 1 according to the first embodiment.

  Hereinafter, in order to facilitate understanding of the description, the terminal pressing portion 4 that extends from one plate surface side to the other plate surface side of the pair of plate surfaces 2A and contacts the round crimp terminal 50 is referred to as the first terminal pressing portion. Called 4A. The terminal pressing portion 4 that extends from the other plate surface side to the one plate surface side and contacts the round crimp terminal 50 is referred to as a second terminal pressing portion 4B. Further, when the first terminal pressing portion 4A and the second terminal pressing portion 4B are collectively referred to as a terminal pressing portion 4.

For this reason, in the fixture 1 which concerns on this embodiment, if the four terminal press parts 4 are projected on the virtual plane orthogonal to an insertion direction, 4 A of 1st terminal press parts will be clockwise centering on the insertion part 2. The second terminal pressing portion 4B, the first terminal pressing portion 4A, and the second terminal pressing portion 4B are arranged in this order.

  Moreover, the terminal temporary fix | stop part 2B provided in the width direction both ends of 2 A of board surfaces protrudes in the direction inclined to the other board surface 2A side from the said board surface 2A, as shown in FIG. That is, the terminal temporary fixing portion 2B provided on the plate surface 2A on the left side of the paper surface is inclined toward the plate surface 2A side on the right side of the paper surface. On the other hand, the terminal temporary fixing portion 2B provided on the plate surface 2A on the right side of the paper surface is inclined toward the plate surface 2A side on the left side of the paper surface.

2. Features of the fixture according to the present embodiment In this embodiment, the fixture 1 can be easily removed. That is, when removing the fixture 1, as shown in FIG. 22A, the insertion portion 2 may be elastically deformed so that the pair of plate surfaces 2A are brought close to each other.

At this time, if the four terminal pressing portions 4 are not provided with the second bending portion 41B on the front end side in the extending direction of the second terminal pressing portion 4B, as in the first embodiment, the following possibilities are obtained. is there.
That is, there is a high possibility that either one of the first terminal pressing portion 4A and the second terminal pressing portion 4B will bite into the other. And if any one tip bites into the other, the pair of plate surfaces 2A cannot be displaced sufficiently close to each other, so that it is difficult to remove the fixture 1.

  On the other hand, in this embodiment, as shown in FIG. 22B, when the pair of plate surfaces 2A come close to each other, the tip of the first terminal pressing portion 4A and the tip of the second terminal pressing portion 4B approach each other. Since the curved surface of the second bending portion 41B slides relative to the curved surface of the first bending portion 41A, the second terminal pressing portion 4B rides on the first terminal pressing portion 4A.

  For this reason, the tip of either one of the first terminal pressing portion 4A and the second terminal pressing portion 4B does not bite into the other, and the pair of plate surfaces 2A can be displaced sufficiently close to each other. Can be easily removed.

Moreover, since the terminal temporary fix | stop part 2B protrudes in the direction inclined to the board surface 2A side, the rigidity and intensity | strength of the insertion part 2 (especially board surface 2A) can be improved.
And when terminal temporary fix | stop part 2B protrudes in the direction inclined to the plate surface 2A side, compared with the case where terminal temporary fix | stop part 2B protrudes in parallel with plate surface 2A, the amount of biting into attachment object 60 Can be easily removed.
