According to a ninth configuration of the present invention, in any one of the first to seventh configurations,
A connection holding device, characterized in that a plurality of conductor contacts having contact portions that elastically protrude on both front and back surfaces of the same position of the plate-like insulator are arranged at different positions and constitute a component. is there.

Since the present invention has the above-described means configuration, it has the following effects.
In the first configuration, when the locking portion of the holding member is locked to the locking receiving portion of the plate-like member, the holding member is separated from the surface of the plate-like member from a position having a predetermined dimension from the locking portion. To tilt. Since the holding member is made of an elastic linear member, when the inclined end is pressed against the surface of the plate-like member, the engaging leg portion of the holding member penetrates the through hole of the plate-like member. At this time, since the portion of the inclination start point of the holding member presses the plate member, the pressing force is applied to the plate member in the same direction as the pressing direction to the holding member. Is added.

In this state, the circuit board having a through hole at the same position as the through hole of the plate-like member is overlapped on the back side of the plate-like member, and the engagement leg portion of the holding member is also passed through the through-hole of the circuit board, When the holding portion is engaged with the edge of the through-hole and the presser hand applied to the press-holding member is released, the press-holding member is an elastic member, so that an elastic force is generated to escape from the through-hole.
However, since the holding portion is related to the edge of the through hole of the circuit board, it cannot be pulled out, and the elastic force acts as a force for pressing the circuit board against the plate-like member. This pressing can be performed by stacking two circuit boards, or two circuit boards are arranged horizontally and one of the holding parts is engaged with the through hole of one circuit board and the other is held. By engaging the portion with the through hole of the other circuit board, the two circuit boards can be pressed and fixed to the plate-like member in a state where they are horizontally adjacent to each other.

  Therefore, when two circuit boards are stacked, each electrode (pad) row is opposed to each other, and a plate-like connector in which contacts electrically connecting pads facing each other are arranged in a plane is sandwiched. Thus, the electrical connection between the two circuit boards can be made, and also when the two circuit boards are arranged horizontally next to each other, the electrode rows of the respective circuit boards are parallel to the adjacent sides of the circuit boards. If the respective electrodes correspond to each other, two circuits arranged horizontally and horizontally can be obtained by sandwiching a plate connector with contacts arranged in parallel with each other to electrically connect the individual electrodes of both substrates together with the circuit board. There is an effect that electrical connection between the substrates can be performed.

  Also, when trying to connect for operation handling, align the circuit board and the connector with a well-known technique such as an alignment pin, align the through hole of the plate member and the through hole of the circuit board, and hold the holding member It is only necessary to push each of the engagement leg portions into the through-holes. To remove them, simply operate the two bent portions of the through-holes with the fingers so that the holding portion is detached from the edge of the through-hole of the circuit board. There is an effect that the handling operation is very simple as compared with the holding structure with screws and nuts such that the holding member is pulled out of the through hole by the elasticity of the holding member and the connection is released.

In the second configuration, the shape from the locking portion of the presser holding member to the inclined bending point is not a simple U shape as in the first configuration, but is a U shape from a predetermined position after becoming a U shape. In the same plane, it is bent so as to be close to both sides in parallel to the central portion, and then the linear members on both sides are bent symmetrically so as to be parallel in the same plane at a position of a predetermined dimension therefrom. Therefore, even if the locking portion is not at the center of the U-shape but at both ends, the inclined bending point is on the inner side from both ends, so that the locking receiving portion of the plate-like member is located on both side edges of the plate-like member. However, as long as the locking portion of the holding member is locked to the locking receiving portion, the inclined bending point is located at the center of the plate member, and the pressing force applied to the holding member is applied to the plate member. Will be communicated.
Thus, there exists an effect that the latching receiving part of a plate-shaped member can be provided in the both-sides edge part which is easy to form.

  In the third configuration, since a plurality of holding members are provided on one plate-like member, the circuit board and the connector that is sandwiched between the circuit board and the plate-like member are firmly plate-like. There is an effect that it can be pressed against the member and held.

  In the fourth configuration, when a plurality of pressing holding members are provided, the pressing holding members are arranged so that their locking portions are back to back, so that the pressing force between the plate-like member and the circuit board or the like is It has the effect of adding a good balance.

  In the fifth configuration, since the latch receiving portion provided on the plate-like member has a hook shape, it can be formed by press punching or the like, and the manufacturing process is simplified.

  In the sixth configuration, since the holding portions are bent inward so as to face each other, the holding portion is detached from the edge of the through hole of the circuit board simply by opening the bent portion to the through hole with a finger. There is an effect that the release operation becomes easier.

  In the seventh configuration, since the cylindrical guide tube having the inclined surface that invites the insertion opening portion is provided in the through hole of the plate-shaped member, the insertion of the engagement leg portion of the holding member becomes smooth. effective.

  In the eighth configuration, on the back side (circuit board side) of the plate-like member, a connector in which a plurality of conductor contacts having contact portions at two places on the surface of the plate-like insulator on the circuit board side are arranged in parallel. Therefore, the electrical connection between the two circuit boards arranged horizontally can be held.

  In the ninth configuration, since a connector in which a plurality of conductor contacts having contact portions protruding elastically on both the front and back surfaces at the same position of the plate-like insulator are arranged and arranged is one element of the configuration, the electrode (pad) The effect is that the connection between the circuit boards can be maintained by aligning the two circuit boards whose arrangement matches the connector and holding the connector between the plate-like member and the holding member. There is.

  The inclined shape from the bending point of the presser holding member is a curved shape that warps upward so that the force that the presser holding member presses against the plate-like member is as uniform as possible over the entire presser holding member. It is the best embodiment.

  In the present invention, the position of the electrode (pad) on the circuit board needs to coincide with the position of the contact portion of the connector. As a means for the alignment, a guide cylinder is provided in the through hole of the plate-like member, and this guide The best embodiment is to allow alignment by fitting the through hole of the connector and the through hole of the circuit board into the cylinder.

Embodiments of the connection holding device of the present invention will be described below with reference to the drawings.
FIG. 1 is a three-side view of a first embodiment of the present invention. (A) is a side view, (b) is a top view, and (c) is a front view.
The constituent members are a holding member 1 and a plate-like member 2. The presser holding member 1 is made of an elastic linear member, and when viewed in (b), has a shape in which the lower side extends above the U-shape, and the central side of the U-shape becomes the locking portion 4. ing. As shown in (a), it is bent and inclined upward from a position extending from the locking portion 4 by a predetermined distance.
The front end is bent at a substantially right angle to form an engaging leg portion 5 and further, at a predetermined dimension, as shown in FIGS. (B) and (c), the holding portion is bent at a right angle so that the front ends face each other. 7 and 7 are formed.

The plate-like member 2 is made of a metal or other rigid body, and a hook-like locking receiving portion 3 for locking the locking portion 4 of the holding member 1 and the engaging leg portion 5 are inserted. Two through-holes 6 are provided.
Since the holding member 1 is made of an elastic material, when the engaging leg 5 is pushed toward the through-hole 6, a reaction force is generated which always goes down but returns.
When lowered, the tips of the holding portions 7 and 7 protrude outward from the through hole 6 as shown in FIG. 5B, so that they cannot be inserted into the through hole 6 as they are. By opening the holding member 1, it can be inserted into the through hole 6.

When the opening force is removed after the holding portions 7 and 7 come out on the lower surface side of the plate-like member 2, the holding portions 7 and 7 return to their original positions due to elasticity, so that they are not caught by the edges of the through holes 6 and 6. .
However, since the force of pulling out from the through holes 6, 6 acts due to the elasticity of the bending inclined portion of the holding member 1, the holding parts 7, 7 exert a force that strongly presses the lower surface periphery of the through holes 6, 6. Has occurred. Accordingly, a plate-like product having through holes similar to the through-holes 6 and 6 is applied to the lower surface of the plate-like member 2 so that the upper and lower through-holes coincide with each other, and the holding portions 7 and 7 are attached to the plate-like product. When the pressing force against the pressing and holding member 1 and the force to open the engaging leg 5 are removed, the holding portions 7 and 7 press the plate-like product against the lower surface of the plate-like member 2. Become. This is the same even if there are two or three plate-like products.
It is also possible to hold and hold two plate-like products in a side-by-side state on the same plane with the boundary between the two through-holes 6, 6.

  These holding structures can be connected between circuit boards by holding a plate-like connector for electrical connection between two boards between two circuit boards, and are arranged on the same plane. By connecting and holding a plate-like connector for electrical connection between circuit boards between the circuit board and the plate-like member, electrical connection between the circuit boards can be performed.

Further, in the operation of holding the holding member, the holding portion 4 of the holding member 1 is locked to the receiving portion 3 of the plate-like member 2 and the engaging leg portion 5 is held by the holding portions 7 and 7 through the through holes 6 and 6. It is only necessary to open it so that it can be inserted, and to release the hand when the holding portions 7 and 7 protrude to the lower surface of the through hole of the lowermost plate-like product. In this case, the mutual alignment between the plate-like products may be provided with a guide tube in the through-hole of the plate-like member 2 or a well-known guide pin.
When releasing the connection holding, it is only necessary to open the holding portions 7 and 7 that are hooked on the edge of the through hole of the plate-like product so as to be able to get out of the through hole, and it can be performed by a very simple operation.
In addition, you may make it the latching | locking part 4 of the holding | suppressing holding member 1 latch to the latching receiving part 3 of the plate-shaped member 2 so that rotation is possible.
