Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to, for example, a connector used for connecting an electric device or an electronic device to be measured to a measuring instrument or a checker, and a laminated board used for the connector.

[0002]

2. Description of the Related Art As a checker connector between devices of this type, for example, Japanese Patent Application Laid-Open No.
A connector having a configuration disclosed in Japanese Patent Application Laid-Open No. 68917/1989 is known as a conventional example.

In this conventional connector, a plurality of needle-like pins (contact probes) are used as contact terminals with an electric device or an electronic device to be measured. In most cases, a flexible cable is used for a connection portion at a portion to be measured or checked on the electric device or electronic device to be measured. In the above-mentioned conventional example, the flexible cable used is not described in detail, but the configuration of a generally used flexible cable is, for example, a large number (for example, 20 or more) of 0.2 mm wide conductive wires. Are printed at 0.5 mm pitch.

[0004] The contact probe used as a contact terminal for individually contacting the ends of the respective conductors of the flexible cable having such a configuration includes a cylindrical body having a predetermined length, and a cylindrical body having a predetermined length. It is formed of a coil spring disposed inside the body and a pin of a predetermined length which is urged in a direction protruding by the coil spring, and the pin is slidable on both ends of the cylindrical body ( It is formed in a protruding state.

[0005] This contact probe has a cylindrical body having a diameter of about 0.5 mm, a pin having a diameter of about 0.3 mm, and a tip having an extremely small diameter of about 0.1 mm. The contact probes having such a very small diameter are arranged in a staggered manner so as not to be in contact with each other and to have a predetermined interval, and are attached to the connector so as to match the pitch of the conductive wires of the flexible cable. And, by using a spring, a plurality (for example, 2
When the (0 or more) pins are in contact with the flexible cable, the individual pins come into elastic contact with each other, so that even one of the plurality of pins does not cause a contact failure.

In recent years, the number of components used has been reduced with the advancement of miniaturization and high performance of electronic components, and the size of substrates on which they are mounted and the wiring space have been rationalized. As the electronic device is further reduced in size and weight, as a flexible cable used for that purpose, for example, as shown in FIG. 10, the entire width of the flexible cable 50 is suppressed to 13.8 mm, and the width of the flexible cable 50 is reduced to 13.8 mm. A configuration in which 45 conductors 51 each having a width of 0.1 mm are wired at a pitch of 0.3 mm, and at the end of the flexible cable 50, the ends of each conductor 51 are widened and the contact terminal portions 52 are alternately formed. Has appeared.

[0007]

In view of such a situation, the use of a contact probe as in the conventional example requires a flexible wiring having such a small pitch in terms of both configuration and size. There is a problem that the cable cannot be used or is extremely difficult.

[0008] Even if the outer diameter of the cylindrical body and the outer diameter of the pin of the conventional contact probe can be further reduced to about 0.3 mm and about 0.15 mm,
Arranging as many as 45 probes so that the probes do not contact each other in accordance with the conductor pitch of the flexible cable is difficult in terms of work itself, and the probe itself allows the cylinder and the pin to slide. From that
Although the pins of each probe are slightly rattled with respect to the cylinder, it is unavoidable that the electrical contact resistance between the cylinder and the pin in each probe varies among many probes. In actual use, there arises a problem that an accurate check cannot be performed due to a variation in contact resistance or the like due to contact resistance and displacement.

Further, in the production of a probe for a contact having a very small diameter, automation is not possible, and each probe is made one by one by a craftsman who has a special talent called a so-called "takumi" who is more than skilled. Therefore, the cost of the probe increases, and the cost of a connector using a large number of probes inevitably increases.In addition, as the contact probe becomes finer, the contact end face of the flexible cable with the conductor becomes worn. Also, there is a problem that it becomes difficult to use for a long time.

Therefore, in this type of connector, the use of the contact probe cannot follow the progress of the flexible cable, and there is a problem that must be solved by developing a new contact means.

[0011]

According to the present invention, as a specific means for solving the problems of the prior art, a base member and a front end portion are attached to the base member so as to be openable and closable. A movable member provided with a member, and a laminated substrate attached to the inside of the base member and provided with a contact terminal group at least at a tip end side, and the contact terminal group of the laminated substrate and the pressing member measure or check. It is intended to provide a connector characterized in that a terminal portion on the device side is sandwiched.

The base member is provided with a concave portion at a central portion along the length direction for mounting the laminated substrate and guiding or positioning insertion of the terminal portion on the device to be measured or checked; The pressing member has an elastic member attached to the holding surface; the distal end of the base member is formed to be longer than the distal end of the movable member; An additional requirement is to provide a groove for collecting connected external lead wires; and to form a window of a predetermined size in the movable member.

According to the present invention, there is provided a laminated board used by being attached to a connector, wherein the laminated board has a contact terminal group for contacting a terminal of a device to be measured or checked on a tip end side thereof. It is another object of the present invention to provide a laminated board characterized by comprising a terminal terminal group electrically connected to each contact terminal group and connected to a measuring or checking device side.

Further, the laminated board is formed by laminating a plurality of insulating plate members formed by printing one or more of the contact terminal group, the terminal terminal group or the conductive wire by printing means. It is included as a requirement.

The connector according to the present invention uses a laminated board having a group of contact terminals. The group of contact terminals on the laminated board can be arbitrarily formed at a small pitch.
As a result, it is possible to cope with a flexible cable in which wiring at a small pitch is performed in an appropriate state.

The laminated board according to the present invention can be easily formed even if the contact terminal group and the terminal terminal group have high dimensional accuracy and a small pitch. As a result, the conductor can be easily routed.

By setting mm, electric loss (attenuation) is suppressed.

The insulating plate members 4a to 4a
4d is adhered in a laminated state using an appropriate adhesive and integrated to form one plate substrate. In this case, the layers are laminated in a state where the positions of the corresponding small holes in each of the insulating plate members are completely matched, and each of the small holes is formed from the fourth-layer insulating plate member 4d to the first-layer insulating plate member 4a. This is a through hole state in the substrate, which penetrates through the substrate.

In particular, in the illustrated embodiment, the laminated substrate 4 is formed by laminating four insulating plate members 4a to 4d, so that the conductors 23 and 28 can be easily routed, and one of the contact plates One contact terminal of the terminal groups 17 and 18 is, for example, 1.0 mm long and 0.3 mm wide,

As described above, the four insulating plate members 4a to 4a
The plate substrate on which 4d is laminated is immersed in an appropriate electrolytic solution and first plated with copper. In this plating step, the contact terminal groups 17 and 18 and the terminal terminal groups 19a and 19a formed on the surface of the first insulating plate material 4a are formed.
9b is plated, and a plating attachment portion 33 formed on the fourth-layer insulating plate material 4d on the bottom surface side;
Plates 34 and 35 are also plated, and at the same time so-called through-hole plating is applied to each of the small holes, so that the contact terminal groups 17 and 18 and the terminal terminal groups 19a and 19b in the first insulating plate member 4a and the fourth layer Are electrically connected to the plated portions 33, 34, 35 of the insulating plate material 4d by through-hole plating, and the conductive wires 23, 28 facing the small holes in the second and third layers. The parts are also electrically connected to the corresponding parts by through-hole plating.

That is, the conductive wire 23 formed on the second-layer insulating plate member 4b electrically connects the contact terminal group 18 and the terminal terminal group 19b in the second row in a corresponding state, respectively. The conducting wires 28 formed on the eye insulating plate 4c electrically connect the first row of contact terminal groups 17 and the terminal terminal groups 19a in a corresponding state.

The plate substrate after the copper plating step is further subjected to nickel plating and gold plating. In particular, each contact terminal group 1 in the proximity state is formed by the plating layer formed in these plating steps.
The surfaces of 7 and 18 are each formed into a smooth (rounded) trapezoidal shape with a slight protrusion, and the laminated substrate 4 is completed.

The laminated substrate 4 having such a configuration is used by being attached to the base member 2. As shown in FIG. In this state, the distal end of the movable member 3 is always closed by the bias of the spring, and the elastic member 13 of the pressing member 11 is in contact with the laminated substrate 4.

In this state, as shown in FIG. 8, when the rear end of the movable member 3 is pushed down, the front end is lifted up with the shaft portion 14 as a fulcrum, and the laminated substrate 4 and the elastic member 13 There is a predetermined gap between them. In this gap,
The connection terminal portion of the device to be measured or checked, for example, the end of the flexible cable 50 is inserted so as to abut against the positioning member 7, and the movable member 3 is returned to its original position as shown in FIG. The end portion of the flexible cable 50 is elastically sandwiched between the flexible substrate 50 and the elastic member 13, and the contact terminals 52 of the flexible cable 50 and the contact terminal groups 17 and 18 of the laminated substrate 4 are maintained in pressure contact with each other. You.

It is assumed that there is some variation in the height of the upper surfaces of the contact terminal groups 17 and 18 or that the concave portions 5 of the base member 2 are not horizontal,
The pressing member 11 attached to the movable member 3 is
Even in a distorted state where it cannot be uniformly pressed in a horizontal plane, the elastic member 13 elastically presses and clamps the flexible cable 50 to absorb the variation and the distorted state and press the whole substantially uniformly. Not only does contact failure due to displacement or the like not occur, but also the contact terminal group 17,
Since there is no loss in electrical resistance and the contact resistance is extremely small in the laminated substrate 4 provided with 18, accurate measurement or check can be performed.

The width of the concave portion 5 of the base member 2 and the width of the laminated board 4 fitted and attached to the concave portion 5 are formed corresponding to the width of the flexible cable attached to the device to be measured or checked. For example, the width of the flexible cable is 13.8 mm
In this case, the widths of the concave portion 5 and the laminated substrate 4 are also formed to have widths substantially corresponding thereto, whereby the contact terminal portion 52 of the flexible cable 50 and the contact terminal group 17 of the laminated substrate 4
The positional relationship with the position 18 can be set accurately. In addition,
In the case of the concave portion 5, it is preferable that the concave portion 5 is formed to be slightly wider (at most about 0.1 mm) than the width of the flexible cable.

The distal end of the base member 2 is formed slightly longer (about 2 to 5 mm) than the distal end of the movable member 3. By forming in this manner, the end of the flexible cable to be inserted is guided, and the work of inserting the flexible cable into the concave portion 5 becomes easy.

FIGS. 10 and 11 show a second embodiment. In this embodiment, the base member 2
And the shape of the movable member 3 are slightly changed, and the basic configuration and operation state are the same as those of the first embodiment. Therefore, the same portions are denoted by the same reference numerals, and detailed description thereof will be omitted.

The connector 1 according to the second embodiment
In the figure, the length of the movable member 3 is slightly shortened and the shape of the rear end of the base member 2 is changed. That is, on the rear end side of the base member 2, the upper surface side is formed as a tapered surface 2a, and a groove 2b having a predetermined width and a predetermined depth is formed on a peripheral surface near the rear end, that is, on the side surface and the upper surface. The external lead wires 40 connected to the measuring instruments connected to the terminal terminal groups 19a and 19b of the laminated substrate 4 are bundled by a band 41 or the like so as not to be separated.

The movable member 3 has a rear end portion with a shorter length, a window 3a is formed on the upper surface, and the rear end portion is bent downward, so that the effect of a rib, ie, strength is not reduced. Bent portion 3b is formed. Since the rear end portion is short and the window portion 3a is formed as described above, the terminal terminal groups 19a and 19b of the laminated substrate 4 can be almost visually recognized from the upper surface side, so that the connector 1 is in an appropriate state. For example, it can be checked using a tester or the like.

As described above, in the second embodiment,
By forming the tapered surface 2a and the groove 2b on the rear end side of the base member 2 and shortening the length of the movable member 3 and forming the window 3a, the overall weight is reduced without impairing the function. You can do it.

In any case, the connector 1 according to the present invention uses a laminated board having a contact terminal group and does not use a contact probe. Therefore, the wiring pitch of the flexible cable for measurement or check is zero. The contact terminals can be formed with an accurate pitch correspondingly even when the distance becomes 0.3 mm or less, whereby the measurement or checking function is significantly improved.

[0047]

As described above, the connector according to the present invention comprises a base member, a movable member having a distal end portion attached to the base member so as to be openable and closable, and having a pressure contact member at the distal end portion. A laminated substrate provided inside the base member and provided with a contact terminal group at least on the distal end side, and the terminal section on the side of the device to be measured or checked is sandwiched between the contact terminal group of the laminated substrate and the pressing member. With this configuration, the contact terminals on the laminated board can be arbitrarily formed at a small pitch, which is suitable for a flexible cable with a small pitch wiring unlike the conventional contact probe. This provides an excellent effect that accurate measurement and checking can be performed because contact failure does not occur.

Further, the laminated board according to the present invention is a laminated board used by being attached to a connector, and the laminated board is provided at its tip end with a contact which comes into contact with a terminal of an apparatus to be measured or checked. In addition to providing the terminal group, the contact terminal group and the terminal terminal group are electrically connected to each of the contact terminal groups and are configured to have the terminal terminal group connected to the measuring or checking device side. Even if the pitch is small, it can be easily formed, and even if the width dimension of the laminated substrate itself is narrowed, since it is a laminated type, there is an excellent effect that the lead wires can be easily routed.
