Description

  The present invention relates to a wiring body connection structure. Specifically, the present invention relates to a wiring body connection structure for electrically connecting connection electrodes provided in two or more various wiring bodies.

  For example, a ZIF (Zero Insertion Force) connector is often employed to electrically connect a flexible wiring board and a rigid wiring board. The ZIF connector includes an insulating housing, a spring contact juxtaposed to the housing, and a presser plate that presses an end of the flexible wiring board against the spring contact for electrical connection. Yes. In the ZIF connector, the connection electrode is elastically applied to the contact electrode by inserting a connection electrode of the flexible wiring board to the contact electrode forming portion in the housing and then applying a pressing force through the presser plate. To be electrically connected. Since the ZIF connector can connect the flexible wiring board in a detachable manner, it can easily cope with a component failure and can easily recycle the wiring board and the electronic component.

Japanese Patent Publication No. 7-24230

  In the conventional ZIF connector, it is necessary to provide a large number of contact electrodes inside a resin molded housing. Further, it is necessary to provide a mechanical mechanism that can lock the connection electrode of the flexible wiring board while pressing the connection electrode against the contact electrode and can release the lock. For this reason, the structure of the connector becomes very complicated. In addition, when the arrangement interval of the connection electrodes is reduced, high dimensional accuracy is required for the arrangement of the contact electrodes and the like, and the manufacturing cost of the connector increases.

  The ZIF connector is fixedly provided on the rigid wiring board and detachably connects the flexible wiring board. Therefore, in order to mount the ZIF connector on the wiring board, it is necessary to connect a large number of contact electrodes provided on the housing and the connection electrodes of the wiring board with solder or the like. It takes time and effort.

  Further, the conventional structure is configured to connect by inserting the connection electrode into the gap provided with the contact electrode. For this reason, when connecting, the connection electrode by the side of a flexible wiring board contacted a contact electrode, a housing, etc., and there existed a problem that it was easy to be damaged.

  In the present invention, various wiring bodies including a flexible wiring board can be detachably connected with an extremely simple structure without requiring a special housing or the like, and the connection electrode is damaged even when repeatedly attached and detached. It is an object of the present invention to provide a wiring body connection structure that does not occur.

  The present invention is provided in two or more wiring bodies stacked so that corresponding connection electrodes are conductive, and at least two or more of the wiring bodies, and these wiring bodies are guided from a direction orthogonal to the stacking surface to be predetermined. Positioning means for positioning and laminating at the laminating position, and a clip capable of elastically pinching and fixing the connection electrode forming region of the laminated wiring body.

  The type of the wiring body is not particularly limited, and can be applied to various wiring bodies as long as they have connection electrodes that can be brought into contact by stacking. For example, it can be applied to a normal rigid wiring board or a flexible flexible wiring board. Further, the present invention can be applied to a wiring board on which various electronic components such as a mother board are mounted. Furthermore, the present invention can also be applied to connection of a flat cable or the like formed with parallel coated conductors.

  The present invention can also be applied when connecting the same type of wiring bodies. For example, not only can a rigid wiring board and a flexible wiring board be connected, but it can also be applied to the connection between flexible wiring boards and between rigid wiring boards.

  Furthermore, by providing the positioning means on both sides of the wiring body having the connection electrodes on both sides, it is possible to laminate three wiring bodies and make the connection electrodes conductive with each other.

  In the present invention, at least two or more of the wiring bodies are provided, and positioning means for guiding and positioning these wiring bodies from a direction orthogonal to the lamination surface at a predetermined lamination position is provided.

  By providing the positioning means, the corresponding connection electrode can be reliably positioned and conducted. And it is comprised so that the laminated wiring body can be guided and positioned from the direction orthogonal to a lamination surface. For this reason, when attaching and detaching the wiring body, the electrodes are not rubbed and damaged, and the present invention can be applied to a connection structure that is repeatedly attached and detached.

  The form of the elastic clip is not particularly limited. For example, a clip having a substantially U-shaped cross section can be employed, and the ends of the wiring bodies can be bundled and elastically held in the U-shaped space.

  Moreover, the material which comprises an elastic clip is not limited, either, The thing formed with the metal and resin can be employ | adopted. By adjusting the material constituting the clip and the dimensions of the clip, the clamping pressure can be set according to the number of connection electrodes, the form of the wiring body, and the like, and electrical conduction between these wiring bodies can be reliably performed.

  The method for attaching the clip to the wiring body is not limited. For example, two wiring bodies can be laminated in advance and a clip can be attached. Furthermore, it is possible to insert and connect the wiring body that has been positioned and laminated to a clip whose opening has been expanded with a dedicated tool or the like.

  Further, it is possible to connect one wiring body and the clip in advance by fastening them together by bonding or the like and inserting another wiring body into the opening of the clip. Also in this case, it is possible to prevent the connection electrode from being damaged by configuring the positioning means so that the connection electrode does not contact the other electrode up to a predetermined stacking position.

  On the other hand, in order to release the connection of the wiring body, the wiring body is pulled out against the elastic clamping force of the clip, or the wiring body is removed by releasing the elastic clamping force of the clip.

  In this invention, since the connection electrode on a wiring body can be directly connected, the housing and contact electrode like the conventional ZIF connector are unnecessary. Further, since the laminated wiring bodies are connected so as to be elastically bundled, it is not necessary to provide a connector provided with a separate connection electrode on the wiring body. Therefore, not only can the manufacturing cost of the connector part be reduced, but the work of connecting the connector to the wiring body can be omitted. Furthermore, since the connection structure can be configured using the edge of each wiring body, space saving can also be achieved.

  The invention described in claim 2 is a first positioning member, wherein the positioning means is mounted on the first wiring body and has a first positioning portion disposed on a side portion of the connection electrode formation region; A second positioning member that is attached to the second wiring body and has a second positioning portion that fits with the first positioning portion is provided.

  Each wiring body can be positioned with high accuracy by providing a positioning member for each wiring body to be laminated and fitting the positioning members to each other.

  The position where the positioning portion is provided is not particularly limited as long as it is a side portion of the connection electrode formation region. For example, one positioning part can be provided so as to face each other with the connection electrode forming region interposed therebetween, and the other positioning part can be sandwiched and positioned between the one positioning part. Alternatively, one positioning portion may be provided so as to surround the connection electrode formation region, and the other positioning portion may be configured to be fitted and positioned in the positioning portion.

  Further, in the wiring body in which circuits are formed on both sides, the first positioning portion is formed on the front and back of the wiring body, and the wiring body provided with the second positioning portion is disposed on both sides of the positioning portion. It is also possible to connect three wiring bodies by laminating from the above.

  According to a third aspect of the present invention, the first positioning member and the second positioning member are formed in a plate shape that is stacked and mounted on the wiring body, and side edges of the positioning members Further, a positioning portion that fits each other can be provided.

  By forming the positioning member into a plate shape that is stacked on the wiring body and mounted, the positioning member can be mounted on the surface of each wiring body with high accuracy by adhesion or the like. Moreover, since the lamination | stacking position of a wiring body can be positioned by making the side edge part of each positioning member fit, the thickness of a connection structure can be set small.

  The material which comprises the said positioning member is not specifically limited, A metal plate-shaped material and a resin plate-shaped material are employable. If a resin plate-like member is employed, the positioning portion can be formed so as to overlap the circuit formed on the wiring board.

  In the invention described in claim 4, the positioning portion is provided with a positioning taper portion disposed so as to face the substantially C-shape. By performing positioning using the taper, the wiring bodies to be stacked can be positioned with high accuracy.

  For example, a pair of positioning portions opposed to each other in the shape of a letter C are provided on the inner edge of the first positioning member disposed so as to sandwich the connection electrode formation region of one wiring body, while being stacked and mounted on the other wiring body. In addition, by providing a C-shaped positioning portion corresponding to the first positioning portion on both sides of the second positioning member and fitting these positioning portions to each other, the stacked wiring bodies can be positioned with high accuracy. Can do.

  According to a fifth aspect of the present invention, the positioning means is provided with a pressing means for elastically pressing the first positioning member or the second positioning member toward each other's fitting position.

  By providing the pressing means, the first positioning portion and the second positioning portion can be fitted with high accuracy even when there is a slight gap between the positioning portions. Further, since the laminated wiring boards can be positioned and held with high accuracy, an effect of preventing the laminated wiring boards from being displaced when the clip is attached can be expected.

  According to a sixth aspect of the present invention, a backup portion is provided on the back surface of the connection electrode formation region.

  In flexible wiring boards, etc., since the thickness of the substrate is very thin, there is a possibility that the substrate and the connection electrode may be deformed or displaced when a clip is attached or detached or when a large clamping force is applied. . The backup unit reinforces the connection electrode formation area of the wiring board, prevents the connection electrode and the wiring board from being damaged when attaching and detaching, and absorbs variations in the dimensions of the connection electrode and the base material to clip. Pressure force is applied evenly to the connection electrode forming region to ensure electrical continuity between the connection electrodes.

  In addition, the provision of the backup unit improves handling when a very small wiring body is attached or detached.

  By forming the backup portion with a rigid material, it is possible to prevent the wiring body from being deformed at the time of attachment / detachment to / from the clip, to ensure electrical continuity and to improve attachment / detachment. In particular, by forming the backup portion with a rigid plate, the connection electrode formation region can be held flat and the positioning accuracy by the positioning means can be increased. On the other hand, by backing up with an elastic member, variations in the dimensions of the base material and the connection electrode can be absorbed, and electrical conduction can be ensured.

  The configuration of the backup unit is not particularly limited. The backup portion can be formed integrally with the positioning member, or can be provided separately from the positioning member.

  The backup portion can be provided, for example, by adhering a strip-shaped member to the back surface of the connection electrode formation region.

  According to the seventh aspect of the present invention, a plurality of conductive portions that are conductive in the thickness direction are formed between the connection electrode formation regions that are stacked and conductive, and are anisotropically compressible and recoverable in the thickness direction. A conductive conductive sheet is provided.

  By providing the anisotropic conductive sheet between the connection electrodes, the variation can be absorbed by elastic compression deformation of the anisotropic conductive sheet even if the height dimension of the connection electrode varies. For this reason, even when the shape accuracy of the connection electrode and the wiring body is low, electrical conduction can be ensured. Further, the connection electrode is not directly pressed and contacted, and there is no possibility that the electrode is damaged. The anisotropic conductive sheet that can be employed is not limited as long as it is electrically conductive by being sandwiched between the connection electrodes of the wiring body.

  The invention described in claim 8 is provided with a retaining means for preventing the clip from falling off.

  For example, the member constituting the positioning means may be provided with a fitting hole, while the clip may be provided with a retaining projection that fits into the fitting hole. By providing the retaining means, it is possible to prevent the clip from dropping from the wiring body even when an inadvertent force is applied to the wiring board or the like.

  In the present invention, the clip and the laminated wiring body can be assembled as separate bodies, or at least one wiring body is fixed to the clip and connected to another wiring body. It can also be configured. The method of fixing is not particularly limited. For example, it can be fixed using an adhesive, or the end of the flexible wiring body can be welded and held on a part of a resin clip. By securing the clip and at least one wiring body, handling properties when connecting to another wiring body are improved.
