Abstract

PURPOSE:To enable current to be conducted through a lead wire and achieve releasing after conduction easily and readily by providing a plurality of members for clamping a conductor-exposed part of the lead wire and a guide part for guiding the lead wire while penetrating through clamped part. CONSTITUTION:A positional relationship of each conductor-exposed part 94 of a plurality of insulation coated lead wires 92 is allowed to correspond to the positional relationship of each pair of clamping members (a fixed clamping plate 18 and a movable clamping body 30) which are provided in one row. A slide plate 16 is brought closer to a base part side of the lead wire 92, thus enabling each pair of clamping members to be separated. When the clamping members are joined while a common part of the lead wire 92 is placed within a guide part 22 collectively, the lead wire 92 is held by each pair of clamping members. By moving the slide plate 16 in a direction away from the base part side of the lead wire 92 by a required distance in that state, each exposed part 94 is positioned between each member by strong pressure and held with pressure. Then, an electrode part 32 of each clamping body 30 is electrically connected with each exposed part 94 and current is conducted to each lead wire 92. By separating each clamping member by strong pressure, each lead wire 92 is released.

Description

[Detailed Description of the Invention] [Industrial Application Field] What is the present invention? ! The present invention relates to a device for energizing several insulated lead wires.

[Problems to be solved by conventional techniques and inventions 1 Conventionally,
For example, for an item such as a brushless motor that has multiple node wires, if it is necessary to energize each of the multiple lead wires for product inspection etc., clamp each lead wire one by one with alligator clips, etc. The power was being supplied by the

However, with this type of energizing means, it takes a lot of time and effort to clamp each lead wire to energize and to release each lead wire after energizing. This has become a problem that needs to be improved in situations where release must be carried out quickly and in large quantities.

The present invention has been made in view of the above-mentioned problems existing in the prior art, and its purpose is to energize each of a plurality of insulated lead wires and to energize them after the energization is completed. Extremely easy and quick way to remove lead wires 1
The second is to provide a power-carrying device that can be used.

[Means for Solving the Problems 1] In order to achieve the above object, the current-carrying device of the present invention includes a pair of electrical conductors, at least one of which constitutes iii, for pinching the exposed conductor portion of the insulated lead wire. Squeezing member and part 1
It has a moving part in which one of the pinching members of the pair is held, and a holding part in which the other pinching member is held, and the plurality of pairs of the pinching members are electrically connected to each other. They are provided in a line in an insulated state, the moving part is supported so as to be able to reciprocate with respect to the base body, and the holding member is supported by the moving part so that each pair of pinching members can be freely separated from each other. , a plurality of clamps are formed vertically through the clamping portion formed by each pair of clamping members. The wire is provided with a guide portion for guiding the covered lead wire.

[Function] The positional relationship between the exposed conductor parts provided on one end side of the plurality of insulated lead wires to be energized is made to correspond to the positional relationship between the multiple pairs of clamping members provided in one row. Then, the base side Δ of the absolute Nl-coated lead wire is brought closer to the moving part, and the multiple pairs of clamping members are separated from each other. When the common parts of the multiple insulated wave-layered wires are placed together in the guide part and the multiple pairs of clamping members are put together, the multiple insulated lead wires in the guide part will be separated into multiple pairs. It will be in a state where it is pinched by the pinching member.

In this state, when the moving part is moved relative to the base and away from the base side of the insulated lead wires, the guide part passes through the clamping part by the multiple pairs of clamping members and guides the plurality of insulated lead wires. Therefore, the insulated lead wire slides within the guide portion while being pressed between the multiple pairs of pressing members. As described above, if the positional relationship between the exposed conductor parts corresponds to the positional relationship between the multiple pairs of clamping members, the moving part can be moved the required distance away from the base side of the insulated node wire. As a result, each conductor exposed portion provided on one end side of the plurality of insulated lead wires is located between the multiple pairs of clamping members and is respectively clamped.

Then, since at least one of the multiple pairs of clamping members constitutes an electrode, the t-hole and the conductor exposed portion of each insulated wave layer L-coat wire are electrically connected, and the multiple pairs of clamping members are electrically connected. It becomes possible to supply electricity to each insulated lead wire through the electrode in the pressure member.

When the multiple pairs of clamping members are separated, each insulated lead wire is released. By removing each insulated lead wire and returning the movable part to its original position, it is possible to prepare for the next energization.

A conductor exposed portion 94 from which the insulation coating has been removed is provided at one end of each of the three insulated lead wires 92 to be energized. As shown by the broken line in FIG. 7, when the three insulation-covered lead cottons 92 are grouped together in parallel, the positional relationship between the exposed conductor parts 94 is that the electrode parts 32 provided in one row are It corresponds to the positional relationship of. Further, the motor 90 and the board 10 are fixed in the state shown in FIGS. 5 and 7.

As shown by the two-dot chain line in FIGS. 2 and 3, the opening/closing plate 26 is opened to separate the pair of electrode parts 32 and the fixed clamping plate 18, and the sliding plate 26 is opened as shown in FIG. 5. 16 on the motor 90 side, that is, the insulated lead! Bring it closest to the base of I92. The position of the slide plate 16 when it is brought closest to the motor 90 is determined by the slider 14 being stopped by the stopper 72.

In this state, as shown in FIG. 5, the common parts of the three insulated lead wires 92 are placed together in the guide part 22, the opening/closing plate 26 is closed, and the electrode parts 32 forming a pair are connected to each other. When combined with the fixed clamping plate 18, as shown in FIGS. 5 and 6, the three insulating liquid 1 leads IIg 2 are connected to each f4 pole part 32 and the fixed clamping plate by the elastic force of the compression coil spring 50.

In order to arrange the insulated lead wires 92 within the motor 90, for example, the guide portion 22 may be
This can be easily done by making sure that it protrudes sufficiently to the opposite side, and applying tension between the protruding part and the motor 90.

When the slide plate 16 is slid with respect to the substrate 10 with the insulated lead wire 92 being pinched and moved away from the motor 90, that is, the base side of the insulated lead wire 92, the guide portion 22 is for guiding these three insulated lead wires 92 through the clamping part formed by the multiple pairs of electrode parts 32 and the fixed clamping plate 18, so that there is a gap between the multiple pairs of electrode parts 32 and the fixed clamping plate 18.

It goes without saying that the present invention is not limited in any way by the embodiments described above.

For example, the direction of the reciprocating movement of the moving part and the direction of the rows of increasing pairs of pressing members do not need to be linear. Further, in the above embodiment, elastic force is applied independently to each electrode section by a compression coil spring (elastic means) in order to ensure that electricity is supplied to each exposed conductor section, but this does not necessarily have to be done independently.

Also, if the insulation coating lead wire has a relatively thick coating,
Since the thickness of the exposed conductor part is much thinner than that of the insulating coating, if the clamping surfaces of the pair of clamping members are both flat and hard surfaces, the exposed conductor part can be securely clamped by the clamping members. It may also become difficult to apply electricity due to pressure. In order to ensure that the exposed conductor is energized even when the insulated lead wire has a relatively thick coating, one of the pair of clamping members should be covered with an elastic material such as rubber or sponge. A means of ensuring the clamping of the thin conductor exposed part by making it of a substance so that when the clamping members are brought together, the thick insulating covering part is buried in the rubber-like substance;
By providing a large number of small protrusions, unevenness, protrusions, etc. on the clamping surface of the clamping member, or by dividing one electrode part into several parts and holding each part independently and elastically, the pinching of the exposed conductor part is made easier. Measures can be taken to ensure the pressure. In that case, a conductive rubber-like or sponge-like substance may be used, or an elastic means may be applied to one or both of the pair of pinching members to urge them in the direction in which they pinch. Of course, it is also possible to ensure the current conduction in the negative layer.

[Effects of the Invention] In the energizing device of the present invention, the positional relationship between the exposed conductor portions provided on one end side of the plurality of insulated lead wires to be energized is controlled by multiple pairs of clamping pressures provided in one row. If the members are made to correspond to the order 1 relationship, the moving part will be brought closer to the base side of the insulated lead wire, and the multiple pairs of clamping members will be in an open state.
By placing the common parts of the plurality of insulated lead wires together in the guide part, aligning the multiple pairs of clamping members, and moving the moving part by the required distance in the direction away from the base side of the insulated lead wires. It is possible to extremely easily and quickly energize each of the plurality of insulating coated cotton sheets through the electrical holes of the multiple pairs of clamping members. In addition, since the insulated lead wire can be easily released, the current can be quickly applied repeatedly one after another. Therefore, it is most suitable for energization for product inspection on an assembly line, and the energization work can be easily automated.
