Description

  The present invention relates to a fixture used for attaching and fixing a long body such as an electric wire or various parts to a substrate such as a chassis of an electric / electronic device.

  A large number of long parts such as various parts and electric wires are arranged inside electric devices and automobiles. In order to facilitate work during manufacturing, inspection and repair, and during normal operation of electrical equipment, long objects such as electric wires may be rubbed against other parts and damaged, or may be accidentally pulled out. In order to prevent this from happening, various fixing devices have been devised for arranging and bundling these long bodies and fastening them to an object to be attached such as a panel or a substrate.

  By the way, the clamp part and clamp part which hold | maintain a flat cable with respect to a chassis (board | substrate) like the fixing tool currently disclosed in Unexamined-Japanese-Patent No. 2004-239325 of a well-known type, for example. There are fixtures provided with fitting legs for being fixed to the chassis. This fixture comprises a clamp part on the base and a fitting leg on the bottom surface of the base, and the clamp part has an L-shaped clamp piece protruding from one end of the top surface of the base. A hook on the arrowhead is integrally formed at the tip of the clamp piece.

  A lock piece having a lock claw is erected on the other end of the upper surface of the base. A flat cable is placed on the base, and the clamp piece is elastically deformed downward to lock the hook of the clamp piece to the lock piece. The flat cable can be held between the clamp piece and the base by being engaged and locked with the claw.

JP 2004-239325 A

  The fixing tool as described above requires a separate device in order to remove noise applied to the flat cable because the flat cable is placed on the base.

  In addition, since the storage space configured between the clamp piece and the base is limited, if there are many long bodies such as flat cables, or if there is a need to store additional long bodies, they can be stored. There was something I couldn't do.

  In addition, since there is only one storage space, it has not been possible to separately store and hold separate wires and strip-like flat cables.

  The fixture according to the present invention was made to solve the above-described problem, and an object thereof is to provide a fixture that can remove noise applied to a long body and can hold many long bodies. .

The fixture according to the present invention includes a flat base for holding a long body such as an electric wire, and a plurality of units formed integrally with the base, which are fixing means for attaching the base to a substrate such as a chassis. A fixing device comprising a locking leg and a clamping part formed integrally with the base,
The base is formed with an elastic pressing piece obliquely below the base, and the locking leg is disposed at a predetermined interval in the longitudinal direction of the base so that the base, the substrate and the locking leg are between It is characterized in that a long body storage space is formed.

  Further, it is desirable that a lock piece is formed at the free end of the clamping portion, and a lock claw is formed near the tip of the lock piece so that the lock piece is fixed to the base.

  Further, it is desirable that the locking leg portions are disposed at both ends in the longitudinal direction of the base.

  According to the first aspect of the present invention, in the fixture according to the embodiment of the present invention, the base is formed with the elastic pressing piece toward the diagonally lower side of the base. A long body can be arranged and fixed by sandwiching the long body against a substrate such as a chassis with a substrate, a base, and an elastic pressing piece. Thereby, noise such as static electricity applied to the long body can be removed by flowing it through a conductive substrate such as a metal chassis.

  In addition to the normal long body storage space configured between the holding portion and the base, the second long body storage configured between the base and the substrate and the locking leg portions disposed at a predetermined interval is provided. Since a space is formed, when there are many long bodies to be stored or when it becomes necessary to store additional long bodies, a normal long body configured between the holding portion and the base A long body that cannot be stored in the storage space can be stored in the second long body storage space.

  Furthermore, since there is a second elongated body storage space, when a plurality or different types of elongated bodies are to be separately stored and held, a part of the elongated bodies is usually configured between the holding portion and the base. The other long body is stored in the second long body storage space configured by the base and the substrate and between the locking leg portions arranged at a predetermined interval. Can respond.

  According to the second aspect of the present invention, in the fixing device according to the embodiment of the present invention, a lock piece is formed at the free end of the clamping portion, and a lock claw is formed near the tip of the lock piece. Since the piece is formed in a shape that is fixed to the base, there is an advantage that the long body can be securely fixed in a normal long body storage space constituted by the holding portion and the base.

  According to a third aspect of the present invention, in the fixture according to the embodiment of the present invention, the locking leg is disposed at both ends in the longitudinal direction of the base, so that the base, the substrate, and the locking leg. The second elongate body storage space configured between the two can be maximized in the longitudinal direction of the base.

  In the fixing device according to the embodiment of the present invention, the elastic pressing piece is formed obliquely downward (toward the substrate side) from the base, so that when the elastic pressing piece is attached to the substrate, the elastic pressing piece contacts the substrate and moves upward. Therefore, the elastic pressing piece always comes into pressure contact with the substrate because a force to return to the original shape is exerted by the elastic restoring force which is a property of the synthetic resin or the like of the main body material. Even if the thickness of the cross section of the substrate changes, the flexure of the elastic pressing piece changes to support the fixture 1 and prevent rattling. Therefore, it can respond to the board | substrate of various thickness.

  Moreover, the part which the elongate body to hold | maintain, such as a base and a clamping part, of the fixing device concerning this invention embodiment cuts a corner, chamfers, and has a rounded shape. As described above, even when a long body such as an electric wire is sandwiched between the fixtures of the embodiment of the present invention, the insulation coating of the long body such as an electric wire is not damaged.

  Next, embodiments of the present invention (hereinafter referred to as “examples”) will be described in detail with reference to the drawings. The fixture 1 according to the embodiment of the present invention is preferably formed of a material having both rigidity and elasticity, such as a synthetic resin, and in order to have heat resistance and conductivity, the synthetic resin is made of glass fiber or metal filler. Carbon filler may be mixed, but the material is not limited to this.

  1 is a front view showing a fixture 1 according to an embodiment of the present invention, FIG. 2 is a left side view of FIG. 1, FIG. 2 is a right side view, FIG. 4 is a plan view, and FIG. (The back view is omitted because it appears in line symmetry with FIG. 1.) The fixture 1 according to the embodiment of the present invention is for holding a base 2 formed in a flat plate shape and a long body such as an electric wire. The clamping part 4, the base 2, and the leg part 9 and the locking leg part 11 which are means for fixing the clamping part 4 to a substrate or the like in various devices are integrally formed.

  The base 2 is formed in a flat plate shape, and a flat plate-like sandwiching portion 4 is continuously extended from one end of the base 2 via a flexible portion 3. The lock piece 5 is formed in a substantially V shape with the elastic bent portion 6 as the apex integrally with the clamping portion from the end of 4, the operation portion 8 is at the tip of the lock piece, and the hook shape is near the operation portion 8. The lock claw 7 is formed in a shape.

  In addition, an insertion port 14 having a substantially rectangular shape is formed at the tip of the other end of the base 2. Although it is easy to see in FIG. 2 and FIG. 4, one side of the substantially square of the insertion opening 14 hits the end of the base 2 and is in contact with the side of the end of the base 2. The two sides are formed continuously from the base 2 in a state where the thin plate-like locking legs 11, 11 face each other. A locking portion 15 is formed on the other side of the substantially square shape so as to face the side corresponding to the end of the base 2.

  The upper ends of the locking leg portions 11, 11 on the locking portion 15 side are formed so as to be integrally connected to the locking portion 15. In addition, the nail | claw 12 is each formed in the nail | claw shape in the outer side (back side of the surface which faces each other) lower end (board | substrate direction) of the latching leg parts 11 and 11. FIG.

  A thin plate-like leg portion 9 having a substantially L-shape is formed integrally with the base 2 on the bottom surface side of the base 2, and a convex portion 16 is formed on the end of the leg portion 9 on the side of the locking leg 11. Yes. In addition, a thin plate-like elastic pressing piece 10 which is long in the longitudinal direction of the base 2 is formed on the base 2 from the front and back of the base 2 (front and back as viewed in FIG. 1). It is formed diagonally (towards the bottom side).

  FIG. 6: is a front view which shows the use condition of the fixing tool concerning this invention Example. From the state of FIG. 1, when the clamping part 4 or the operation part 8 of the fixing tool 1 is pressed with a hand or a tool, the flexible part 3 formed thinner than the other parts of the fixing tool 1 is bent and bent. Then, the sandwiching portion 4 moves from the flexible portion 3 as a base point so as to draw a substantially arc in the direction of the base 2, and the flexible portion 3 serves as a hinge. Then, the elastic bending portion 6 of the lock piece 5 enters the insertion port 14, and the lock claw 7 is engaged with the engagement portion 15, resulting in the state shown in FIG.

  Hereinafter, a method for attaching a fixture according to an embodiment of the present invention to a plate-like attachment object 30 (hereinafter referred to as a substrate 30) such as a base will be described with reference to the drawings.

  As shown in FIG. 11, a substantially rectangular hole 31 and hole 32 are previously formed in the substrate 30 inside various devices. A recess 33 is formed on one side of the edge of the hole 32. FIG. 7 is a front view showing a state in which the fixture according to the embodiment of the present invention is attached to the substrate 30. Holding the area around the insertion port 14 of the fixture 1 by hand, the leg portion 9 is inserted into the hole 32 of the substrate 30, and the leg portion 9 is slid in the direction of arrow C.

  When the area around the insertion port 14 is pressed against the substrate 30 as it is, the locking leg 11 moves in the direction of arrow D, and the tips of the locking leg 11, that is, the claws 12, 12 enter the hole 31. Since the tips of the claws 12 and 12 are formed with a slope that gradually decreases inward toward the inside, the claws 12 and 12 can easily enter the hole 31 when pressed lightly. . When the hand is released, the locking leg 11 returns to its original shape due to the elastic restoring force of the main body material, and the hooked portion of the claw 12 of the locking leg 11 is caught by the edge of the hole 31 and locked. As described above, the fixture 1 is attached to the substrate 30. This is convenient because it can be attached simply by lightly pressing the substrate 30 with one hand. FIG. 9 shows this state from the left side.

  Also, from the base 2 of the fixture 1, thin plate-like elastic pressing pieces 10, 10 are integrally formed on the front and back sides, and the free ends of the elastic pressing pieces 10, 10 are on the surface side of the substrate 30. Press contact. The elastic pressing pieces 10 and 10 are pressed by the thickness of the substrate 30 to bend upward (in the direction of the sandwiching portion 4), and a force to return to the original shape is exerted by an elastic restoring force that is a property of the synthetic resin of the main body material. The substrate 30 is always pressed and plays a role of supporting the fixture 1. At this time, the amount of bending of the elastic pressing pieces 10 and 10 varies depending on the thickness of the substrate 30, so that even if the plate thickness of the substrate 30 to which the fixture 1 is attached is changed, the bending of the elastic pressing pieces 10 and 10. It can respond by changing the amount, and will not be rattled.

When a long body 34 such as an electric wire is arranged on the base 2 and the clamping unit 4 or the operation unit 8 is pressed with a finger or the like, the flexible unit 3 is bent and bent, and the clamping unit 4 is in the direction of the base 2. Move to draw an approximate arc. Subsequently, when the elastic bending portion 6 of the lock piece 5 is pushed into the insertion port 14, the lock piece 5 is pushed by the locking portion 15 at the end of the insertion port 14, and the properties of the synthetic resin or the like that is the material of the fixture 1. As a result, the operation portion 8 of the lock piece 5 formed in a substantially V shape bends in a direction approaching the clamping portion 4. When the lock piece 5 enters the insertion port 14, the elastic bending portion 6 is elastically restored and returns to its original shape, so that the lock claw 7 is locked to the locking portion 15 and becomes locked. When the locking claw 7 is locked to the locking portion 15, a clicking sound is generated and the operator's fingers touching the operation portion can feel a moderation, so that the worker can hear the end of work. It can be sensed with a sense of moderation.
With the above procedure, the fixture 1 is in a state in which the long body 34 is held between the sandwiching portion 4 and the base 2 as shown in FIG. (The substrate 30 and the long body 34 are cross-sectional views for easy viewing of the drawing.) Even when the long body 34 is unexpectedly strongly pulled, the locking claw 7 is locked to the locking portion 15. Therefore, the fixture 1 can hold the long body 34 stably. In addition, since the locked state is obtained by simply pressing the operation unit 8 with a finger, the operation is simple.

FIG. 10 is a left side view of FIG. The substrate 30 is a cross-sectional view for easy viewing of the drawing. As shown in this figure, the locking piece 5 enters between the locking leg portions 11, 11, that is, in the insertion port 14, and the locking portion 15 and the locking claw 7 are locked. The lock piece 5 cannot be removed. In this state, even if the latching legs 11 and 11 are pinched and pushed by hand or the like, the lock pieces 5 are inserted between the latching legs 11 and 11. There is no bending inward (in the direction of arrow A). Therefore, the locking legs 11, 11 do not bend inward, and the claw 12 cannot be removed while being locked to the edge of the hole 31 of the substrate 30.
As described above, the fixture 1 is securely fixed to the substrate 30. Unless the locking claw 7 and the locking portion 15 are unlocked, the locking piece 5 does not go out of the insertion port 14, that is, the locking piece 5 has entered the insertion port 14 and is locked. Since the legs 11 and 11 do not bend inwardly (in the direction of arrow A), the claw 12 remains locked to the edge of the hole 31 of the substrate 30 and some external force is applied to the fixture 1 from the outside. Even if the long body 34 is applied or pulled by a strong force, the fixture 1 does not come off from the substrate 30, and the long body 34 can be stably fastened to the substrate 30. .

  FIG. 12 is a perspective view showing a use state of the fixture according to the embodiment of the present invention. The long body 34 is shown in a short and omitted shape.

  A method of removing the electric wire from the fixture 1 according to the embodiment of the present invention and removing the fixture 1 from the substrate will be described in detail below. From the state where the fixture 1 is attached to the substrate 30, that is, the state shown in FIG. 8, FIG. 10, and FIG. 12, when the operation unit 8 of the fixture 1 is slightly pushed toward the clamping unit 4 side with a finger or a tool. The substantially V-shaped lock piece 5 bends slightly in the direction of the sandwiching portion 4, and the locking claw 7 is released from the locking portion 15 and the state shown in FIG. 9 is obtained. Here, the elongated body 34 can be removed from the fixture 1.

  Then, when the latching legs 11 and 11 are pinched from the outside in the direction of the arrow A shown in the drawing with a hand or a tool, the claws 12 and 12 at the tips of the latching legs 11 and 11 are formed in the holes 31 of the substrate 30. Deviate from the edge. The lifting leg portions 11 and 11 are lifted in the opposite direction of the arrow D shown in FIG. 7 to remove the locking leg portions 11 and 11 from the holes 31, and the leg portion 9 is slid in the opposite direction of the arrow C to When the part 9 is lifted in the direction opposite to the arrow B, the fixture 1 is easily detached from the substrate 30.

  A convex portion 16 is formed on the leg portion 9 of the fixture 1 according to the embodiment of the present invention. When attaching the fixture 1 to the substrate 30, the leg 9 is inserted in the direction in which the recess 33 is formed, that is, the hole 32, so that the orientation of the fixture 1 does not have to be mistaken when attaching. For example, when the mounting direction of the tool 1 affects the subsequent work efficiency, the mounting direction can be determined without looking at the procedure table.

  In addition, the fixture 1 according to the embodiment of the present invention may have a shape in which the convex portion 16 is not formed on the leg portion 9. In this case, the fixture 1 has a shape as shown in FIGS. In this case, the holes that are previously formed in the substrate 30 to which the fixture 1 is attached are holes having no recesses 33, that is, two substantially rectangular holes such as the holes 31 having the same shape and the leg portions 9. Since it is sufficient to form an opening at a location corresponding to the locking leg 11, the sheet metal processing cost is further reduced.

  Further, as shown in FIG. 15 (front view) and FIG. 16 which is a bottom view of the fixture 1 according to the embodiment of the present invention, the shape of the outer periphery of the leg portion 9 and the locking leg portions 11 and 11 is a round hole. If it is changed so as to be locked to the edge, it can be attached to the substrate in which a round hole is formed. Since round holes are easier to plate than square holes, the processing cost is even lower. In other words, the holes formed in the substrate are locked to the holes on the outer periphery of the fixing leg portion 9 and the locking leg portion 11 so as to be locked to the edge of the hole regardless of the shape. What is necessary is just to change and form the shape of a part.

  Further, the fixture 1 according to the embodiment of the present invention can be formed in a shape without the leg portion 9. In this case, since only one hole is formed in the substrate in advance, the sheet metal processing cost can be further reduced.

  In addition, the fixture 1 according to the embodiment of the present invention performs treatment such as plating on the surface, so that noise applied to the long body 34 such as an electric wire is passed through the fixture 1 to a conductive substrate such as a metal chassis. It is possible to remove by flowing.

  Further, in the fixture 1 according to the first to fifth embodiments of the present invention, as shown in FIG. 17 (front view) and the left side view thereof, FIG. It can also be fixed by being sandwiched between them. The long body 34 is in a state of being pressed against the substrate by the elastic pressing pieces 10, 10, whereby noise applied to the long body 34 can be removed by flowing it through a conductive substrate such as a metal chassis. It is. Further, in addition to a normal long body storage space configured between the holding portion 4 and the base 2, the locking leg portion 9 disposed at a predetermined interval in the longitudinal direction of the base 2, the substrate 30, and the base. Since the second elongated body storage space formed between the base plate 2 and the locking leg portion 11 is formed, the elongated body 34 can be sandwiched and fixed between the base 2 and the substrate 30. Many long bodies can be clamped and fixed compared to conventional products. Further, when it is desired to separately store or hold different types or a plurality of long bodies, a part of the long bodies is stored in a normal long body storage space formed between the holding portion 4 and the base 2, and others. This long body can be accommodated by storing it in a second long body storage space formed between the base 2 and the substrate 30 and the locking leg portions 9 and 11 disposed at a predetermined interval. . The locking leg portions 9 and 11 are disposed at both ends in the longitudinal direction of the base so that the second elongated body is configured between the base 2, the substrate 30, and the locking leg portions 9 and 11. The space can be maximized in the longitudinal direction of the base 2.

  In the above-described embodiment, the sandwiching portion is shown as a flat plate-like shape, but it is sufficient that the locking piece is attached to the free end portion of the sandwiching portion. Of course, it can be changed in any way according to the shape and amount of the scale.

  The fixing device 1 according to the embodiment of the present invention is used for attaching and fixing a long body such as an electric wire or various parts to an electric / electronic device or a substrate in an automobile, but can also be used for other purposes. is there.
