Abstract

PURPOSE:To facilitate the connecting operation and save the labor by inserting press-type contact pieces of each circuit element into a connecting base body for contact with a conductor of the connecting base body so as to connect circuit elements to each other. CONSTITUTION:To interconnect elements 3A-3D via a connecting base body 2, each press-type contact piece 31 is inserted into the connecting base body 2 through a covering 22. The base body 2 and a circuit element 3 are aligned with each other so that a conductor 21 fits into a groove 32 in the contact piece 31. In a particular example given here, the distance between the lower edges of inserting portions 33 is equal to the width of a protrusion 23, and thus the lower edges of the inserting portions 33 can be aligned with the side edges of the protrusion 23 to achieve proper positioning. After alignment has been made, the contact piece 31 is inserted into the base body 2 to fit the conductor 21 into the groove 32, allowing the conductor 21 to be in contact with both sides of the groove 32. As a result, the circuit element is connected to the conductor 21. The other circuit elements 36 are also connected to the conductor 21 in the same way. This results in the elements 3 being interconnected via the conductor 21 of the base body 2.

[Problem to be Solved by the Invention 1] However, in a circuit device in which a plurality of circuit elements are connected as described above, a large number of connectors are required because the circuit elements are connected to each other via connectors. However, there were problems in that manufacturing costs increased and it took time and effort to connect the connector to the cable.

This invention was made to solve the above problem, and provides a circuit device that can connect circuit elements without using connectors, thereby reducing manufacturing costs and saving labor. The purpose is to provide.

[Means for Solving the Problems 1] In order to achieve the above object, the present invention provides a wiring base formed by covering a plurality of conductive wires arranged in parallel with an insulating resin, and a wiring base of this wiring base. A plurality of circuit elements are electrically connected via conductive wires, and in order to electrically connect the plurality of circuit elements, the circuit elements are pierced through the wiring base and come into contact with different conductive wires respectively. It is equipped with a plurality of pressure contacts.

[Action 1] The pressure contact of the circuit element is pierced into the wiring base, and the pressure contact of the circuit element and the conducting wire of the wiring base are brought into contact. Similarly, for other circuit elements, press contactors are brought into contact with the conductive wires of the wiring base. As a result, the circuit elements are connected to each other via the conductive wires of the wiring base.

[Embodiment 1] Hereinafter, an embodiment of the present invention will be described with reference to the attached FIGS. 1 to 4.

As shown in FIGS. 3 and 4, this circuit device 1 includes:
It is composed of a connection base 2 and a plurality of circuit elements 3 (3A to 3D).

The connection base 2 has a flat plate shape and has a plurality of conductive wires 21. As shown in FIGS. 1 and 2, the conductive wires 21 are arranged on the same plane, parallel to each other, and arranged at regular intervals. In such a state, each conducting wire 21 is covered with a covering portion 22. This covering portion 22 is made of an insulating resin such as P, T F E (polytetra 70 roethylene), polyvinyl chloride, polyimide, etc., and there are conductive wires at locations corresponding to the respective conductive wires 21 on the upper and lower surfaces thereof. A protrusion 23 having an arcuate cross section and extending along the line 21 is formed.

Further, a protective layer 24 is attached to the lower surface of the covering portion 22 . This protective layer 24 protects the tip of the pressure contact 31 (described later) protruding from the lower surface of the covering portion 22, and at the same time prevents a short circuit between the tips. A member is used that has the following properties:

The above circuit element 3 is a multilayer printed wiring board, L
SI and other various circuit elements are used, and here four circuit elements 3A to 3D with different internal circuits are attached. A plurality of pressure contacts 31 extending downward are provided on the lower surface of each circuit element 3.

A groove 32 extending upward from the lower end surface is formed in the widthwise center of each pressure contact 31 . This groove 3
Reference numeral 2 is used to bring the conducting wire 21 into contact with the pressure contact 31 by fitting the conducting wire 21 therein, and its width is made to be approximately the same size as the diameter of the conducting wire 21. Moreover, in order to connect each pressure contact 31 to a predetermined conductor 21, the groove 32 of the negative pressure contact 31 is
The center-to-center distance between the groove 32 and the pressure contact 21 is equal to the center-to-center distance between the two conducting wires 21 connected to the two pressure contact 21, respectively. In addition, at the lower end of the pressure contact 31, located on both sides of the groove 32, stab parts 33, 33 are formed, which gradually become narrower toward the bottom and have sharp lower ends.

The distance W1 between the lower ends of the piercing portions 33 and 33 is
It is made equal to the width W2 of 3.

When the circuit elements 3A to 3D are connected via the connection base 2, each pressure contact 31 is connected to the connection base 2 by the covering portion 22.
Insert from the side. In this case, the groove 32 of each pressure contact 31
Connect the connection base 2 and the circuit element 3 so that the conductor 21 fits into the
It is necessary to perform alignment with the In the case of this embodiment, since the width of the lower edge of the piercing portions 33 and 33 is the same as the width of the protrusion 23, the lower edges of the piercing portions 33 are positioned on both side edges of the protrusion. Positioning can be performed by doing this. Of course, the connection base 2 and the circuit element 3
The connection base 2 and the circuit element 3 may be positioned using each side surface as a reference plane, and the connection base 2 and the circuit element 3 may be aligned thereby.

In any case, in the aligned state, press contact 31
When inserted into the connection base 2, the conductive wire 211 fits into the groove 32 and comes into contact with both side surfaces of the groove 32.

This connects the circuit element 3 to the conducting wire 21. Similarly, the circuit element 3 of the pond is also connected to the conducting wire 21. Then, the circuit elements 3 are connected via the conductive wires 21 of the connection base 2.

In addition, the pressure contact 34 similar to the above is provided on the upper surface of the circuit element 3A, and the connection base 2A of the pond is connected to the pressure contact 34. The circuit device 1 is connected to other circuits, devices, etc. via the connection base 2A.

In the circuit device 1 described above, the pressure contact 31 of each circuit element 3 is inserted into the connection base 2 so that the circuit element 3
The joints are connected, and no connecting connectors are used. Therefore, manufacturing costs can be reduced accordingly. Further, it is possible to save time and effort in connecting the connectors. Furthermore, in order to connect the circuit element 3 and the connection base 2, it is sufficient to simply insert the pressure contact 31 into the connection base 2, making the connection extremely easy. Therefore, the effort required to connect the circuit elements 3 to each other can be further reduced.

In addition, in the above embodiment, the connection base 2 is formed into a flat plate shape, but it is not limited to this. For example, the connection base may be formed into a rectangular parallelepiped shape with a rectangular cross section,
In this way, circuit elements can be attached to each side by arranging conductive wires along the four sides.

Further, although the plurality of conducting wires 21 are arranged at the same intervals, the intervals do not need to be constant. The point is that the distance between the conducting wires and the distance between the pressure contacts that contact each of the conducting wires may be made the same.

Further, the sheathing portion 22 located directly above each conducting wire 21 is given a different code or color, and the insulation displacement contact 3
1 with the same code or color as the conductor 21 to which it is connected, it is possible to connect the pressure contact 31 to a conductor 21 different from the conductor 21 to which it is to be connected when attaching the circuit element 3 to the connection base 2. It is possible to prevent such accidents from occurring.

[Effect of the Invention 1] As explained above, according to the circuit device of the present invention, the pressure contact of each circuit element is brought into contact with the conductor of the connection base by inserting the pressure contact of the circuit element into the connection base,
Since the circuit elements are thereby connected to each other, there is no need to use a connecting connector. Therefore, it is possible to reduce manufacturing costs and save labor. Moreover, since the circuit element and the connection base can be connected by simply inserting the pressure contact of the circuit element into the connection base, the connection work is easy, and therefore, further labor savings can be achieved. The effect of this can be obtained.
