Description

[Detailed explanation of the idea] [Industrial application field]

This invention relates to a socket for reconstitution of lug type electrolytic capacitors.

[Prior Art] Conventionally, when this type of electrolytic capacitor is reconstituted, power lead wires are manually connected to both electrode terminals of the electrolytic capacitor, and voltage is applied to perform electrolytic oxidation treatment. It is chemically formed. Thereafter, the reconstituted electrolytic capacitors were stored one by one in a predetermined position in a storage container or the like. However, such manual reconstitution work is problematic in that it requires many steps, is extremely troublesome, has low work efficiency, and is also dangerous. This invention was made to solve the above problems, and it can be installed on robots etc. to automatically and mechanically perform the re-formation of electrolytic capacitors and the subsequent storage work. An object of the present invention is to provide a socket for reconstitution of electrolytic capacitors that can save labor and greatly contribute to improving work efficiency.

[Means to solve the problem]

The socket for reconstitution of electrolytic capacitors according to this invention has a sliding plate inserted into the socket hole of the socket base, a fixed contact and a movable contact of both poles on the sliding plate, with the phase shifted for each pole, and the sliding plate The movable plate is configured to be able to protrude and retract from the socket hole by reciprocating, and when protruding, the movable contact elastically opens from the fixed contact, and when retracting, the movable contact closes toward the fixed contact. .

[Effect]

In this invention, the movable contact protrudes from the socket hole together with the fixed contact by reciprocation of the sliding plate, and in this state, the sliding plate is moved in the direction in which the terminal of the electrolytic capacitor is introduced between the fixed contact and the movable contact. By moving the terminal, the terminal is inserted between the fixed contact and the movable contact. When the socket base is further moved toward the electrolytic capacitor in this state, the sliding plate, together with the fixed and movable contacts, will eventually be retracted into the socket hole, which will close the movable contact toward the fixed contacts and close these contacts. The terminals of the electrolytic capacitor are chucked between the contacts. In this state, by energizing the movable contact and the fixed contact, voltage is applied to the electrolytic capacitor, electrolytic oxidation treatment is performed, and the electrolytic capacitor is reformed. Therefore, if a robot is equipped with the socket of this invention, it will be possible to automatically carry out the reconversion treatment of electrolytic capacitors as described above, and to place the electrolytic capacitors in the specified location while still chucking them after reconversion treatment. It can be recovered.

【Example】

An embodiment of this invention will be described below based on the drawings. Fig. 1 is a partially sectional front view of a socket according to an embodiment of this invention, Fig. 2 is a side view of the same, Fig. 3 is a plan view of the same, Fig. 4 is a bottom view of the same, and Fig.
6 is a side view of the leaf spring, FIG. 6 is a side view of the fixed contact, and FIG. 7 is a side view of the movable contact. In the figure, 1 is a socket base, 2 is a socket hole, and a pair of left and right leaf springs 3 are provided in the socket hole 2 as shown in the second figure. The leaf spring 3 has a bent recess 3a on the tip side as shown in the fifth figure. As shown in the second figure, the leaf spring 3 is fastened together with the terminal plate 4 to the socket base 1 by one bolt B and one nut N. This terminal board 4 is connected to a power source (not shown). Further, a sliding plate 5 is fitted into the socket hole 2 so as to be slidable up and down. Fixed contacts 6 at both poles along the sliding direction are provided on both sides of the sliding plate 5. As shown in FIG. 6, each fixed contact 6 has a fixed curved contact portion 6a that is curved outward to match the terminal structure of an electrolytic capacitor 10, which will be described later, at each tip. A movable contact 7 is provided on each fixed contact 6 in a connected state. A movable curved contact portion 7 is provided at the tip of the movable contact 7 and is curved in the same direction as the fixed curved contact portion 6a.
A is provided. When the movable curved contact portion 7a protrudes from the socket hole 2, its own elastic force causes the movable curved contact portion 7a to close to the fixed curved contact portion 6a.
It opens from above and, when retracted into the socket hole 2, slides into contact with a leaf spring 3 and is elastically deformed toward the fixed curved contact portion 6a by the biasing force of the leaf spring 3 and closed. Furthermore, the movable curved contact portion 7a engages with the bent recess 3a of the leaf spring 3 at the retracted position into the socket hole 2, thereby restricting the backward movement of the sliding plate 5. A stopper stepped portion is provided on the upper end side of the sliding plate 5 to abut against the upper end wall of the socket hole 2 at the position where the fixed contact 6 and the movable contact 7 protrude from the socket hole 2 to restrict their forward movement in the protruding direction. 5a is provided. Further, a presser element 5b is provided at the center of the tip of the sliding plate 5, which partitions the two poles of the fixed contact 6 and the movable contact 7, and is pressed against a terminal protruding surface of an electrolytic capacitor 10, which will be described later. The sliding plate 5 is biased by a spring 9 in a direction in which the terminal is removed and retracted, and is automatically and mechanically pressurized and moved against the biasing force. That is, when the sliding plate 5 is pressed down against the spring 9 while the socket base 1 is held in a fixed position, the movable curved contact portion 7a protrudes from the socket hole 2 together with the fixed curved contact portion 6a. Performs the first step pressing operation to open. Thereafter, when the socket base 1 is pressed down, the movable curved contact portion 7a retracts into the socket hole 2 together with the fixed curved contact portion 6a and is displaced to the terminal chucking position.
Performs a step press operation. Note that the spring 9 may be omitted. The fixed contact 6 and the terminal plate 4 of the leaf spring 3 are connected by a lead wire 8. The socket constructed as described above is installed in a robot or the like and is mainly used for reconversion treatment of the lug type electrolytic capacitor 10. Generally, the electrolytic capacitor 10 contains an electrolytic solution (not shown) and has both electrode terminals 11. Next, the operation of the above embodiment will be explained. When the sliding plate 5 is moved under pressure against the spring 9 due to the operation of the robot (the first step is pressed down), the fixed contact 6 and the movable contact 7 move forward together with the sliding plate 5, and their fixed curvature is The contact portion 6a and the movable curved contact portion 7a protrude from the socket hole 2, and the movable curved contact portion 7a opens from the fixed curved contact portion 6a. In this state, the entire socket is moved downward toward the electrolytic capacitor 10, and as the fixed curved contact portion 6a and the movable curved contact portion 7a move toward the two pole terminals 11, electrolysis occurs between them. Both terminals 11 of the capacitor 10 are pressed. In this state, the pusher 5b of the sliding plate 5 is pressed against the electrolytic capacitor 1.
It collides with the protruding surface of the terminal 0 and stops. In this state, the socket base 1 further moves downward (second
As a result, the fixed contact 6 and the movable contact 7 are retracted into the socket hole 2 together with the sliding plate 5, and when the movable curved contact portion 7 is retracted, the movable curved contact portion 7
When a is pressed toward the fixed curved contact portion 6a by the leaf spring 3, the two pole terminals 11 are chucked by the movable curved contact portion 7a and the fixed curved contact portion 6a. Then, by energizing the fixed contact 6 and the movable contact 7 via the terminal plate 4 and the lead wire 8, a voltage is applied to both electrode terminals 11 of the electrolytic capacitor 10, and electrolytic oxidation treatment of the electrolytic capacitor 10 is performed. Electrolytic capacitor 10
is reconstituted. Electrolytic capacitor 10 after reconstitution
is transported by a robot to a predetermined location such as a storage box or the like in this state because its two pole terminals 11 are chucked by the fixed curved contact portion 6a and the movable curved contact portion 7a as described above.
The chuck is released by the forward movement of the sliding plate 5, and the material is recovered.

[Effect of the idea]

As described above, according to this invention, by the forward movement of the sliding plate having fixed contacts and movable contacts,
The movable contact opens from the fixed contact, presses and introduces the two pole terminals of the electrolytic capacitor between those contacts, and the two pole terminals can be chucked by the two contacts, and in this state, the two pole terminals of the electrolytic capacitor are connected from the two contacts to the two pole terminals of the electrolytic capacitor. The electrolytic capacitor can be reconstituted by applying a voltage, and the electrolytic capacitor after the treatment can be transported to a predetermined location while still chucked, and recovered after being unchucked at that location. Therefore, it becomes possible to automatically and mechanically perform the reconstitution treatment of electrolytic capacitors, which greatly contributes to improving the work efficiency.
