Description

  TECHNICAL FIELD The present invention relates to a glass terminal plating rack and a glass terminal plating method using the same, and more specifically, a glass terminal plating rack and a glass terminal plating method for plating only lead wires of a glass terminal. About.

  Conventionally, a glass terminal has been provided as a product by performing gold plating on the whole including not only lead wires but also eyelet portions. However, in recent years, there has been a demand for a product form in which only the lead wires are plated without performing the plating process on the eyelet portion that does not require gold plating for the purpose of cost reduction.

As a conventional method for plating only the lead wire portion of the glass terminal, a method of plating the tip portion of the lead wire and plating by rack plating has been proposed (Patent Document 1). In addition, a method has also been proposed in which tips of lead wires are welded to each other and plated by barrel plating (Patent Documents 2 and 3).
According to these methods, the lead wire can be reliably plated, and a glass terminal subjected to high-quality plating can be provided.

However, when plating the lead wires according to the inventions of Patent Documents 1 to 3, the lead wires are bent so that the tip portions of the lead wires are concentrated at one point in order to weld the tip portions of the lead wires. It must be in a finished state. Furthermore, in order to maintain the state where the leading end portion of the lead wire is concentrated at one point, there is a problem that it is necessary to weld the leading end portion of the lead wire, which takes time before plating. Furthermore, after the plating process is performed, there is a problem that it takes time and effort to cut off the welded portion at the tip of the lead wire.
In addition, when the plating process is performed according to the inventions in Patent Documents 2 and 3, the lead wire is often deformed by bending the lead wire. For this reason, the operation | movement which returns the bent lead wire to an original state is needed, and the subject that plating processing became complicated occurred. Furthermore, since the inventions of Patent Documents 2 and 3 plate the glass terminal by barrel plating, not only the lead wire but also the eyelet is plated, and the cost required for the plating process increases. There is also.

  Therefore, the present invention is capable of reliably plating only the lead wire without complicated processing on the lead wire, and capable of performing plating processing with uniform quality without variation, and is a high-quality and inexpensive glass terminal.

FIG. 2 is an enlarged front view of the glass terminal portion arranged in FIG. FIG. 3 is an enlarged side view showing a state where the glass terminal is set. FIG. 4 is a front view of the plating rack showing a state where the lever is rotated. FIG. 5 is an enlarged view of the glass terminal showing a state where the lead wire is pressed. FIG. 6 is an enlarged side view of the glass terminal portion arranged in FIG.

A glass terminal plating rack 10 (hereinafter, simply referred to as a plating rack 10) in the present embodiment is made of a stainless steel material formed in the shape of an elongated round bar on a support plate 20, as shown in FIG. 1. Electrodes 22 and insulators 24 made of silicon, which are also formed in the shape of elongated round bars, are supported by support pieces 26 so as to be alternately stacked in the vertical direction. In the present embodiment, as shown in FIG. 2, two electrodes 22 and two insulators 24 are provided at each support position of the glass terminal 40.
The support pieces 26 that support the electrode 22 and the insulator 24 are arranged in the vertical and horizontal directions of the support plate 20 at a required interval. On the support surface that supports the insulator 24 located at the lowermost part of each support piece 26, an elastic member 28 formed by forming Viton rubber in the shape of an elongated round bar is passed in the horizontal direction in the same manner as the electrode 22 and the insulator 24. It is arranged.

  In the plating rack 10 in the present embodiment, the electrodes 22 and the insulator 24 are supported in a horizontal direction with respect to the plating rack 10 in a state where the electrodes 22 and the insulator 24 are supported by the support pieces 26, and are movable in the vertical direction of the support pieces 26. It is in a state of being stacked in a state. Thereby, if the lead wire 42 of the glass terminal 40 is inserted between the electrode 22 and the insulator 24, the glass terminal 40 which is the object to be plated can be supported by the plating rack 10. Both ends of each electrode 22 are electrically connected to a power source (not shown).

The support pieces 26 are attached to the support plate 20 so as to have substantially the same distance as the maximum outer width of the glass terminal 40. Further, the support pieces 26, 26,... In the horizontal direction are attached so that the height positions of the support surfaces are the same.
As shown in FIG. 3, the support piece 26 is formed so that the cross-sectional shape is substantially L-shaped. The support piece 26 is attached in a state where one end portion 26 a is in contact with the support plate 20. That is, the support plate 20 and the support piece 26 form a substantially U-shaped accommodation portion 30 whose bottom is closed and whose top is open.

Each of the elastic member 28, the electrode 22, and the insulating member 24 described above is accommodated in the accommodating portion 30. Since the accommodating width of the accommodating portion 30 is formed so as to be slightly wider than the diameter of the electrode 22 and the insulator 24, the elastic member 28, the insulator 24, and the electrode 22 are respectively connected from the upper opening of the accommodating portion 30. Just drop them and they will be stacked. In addition, when taking out the electrode 22 and the insulator 24 accommodated in the accommodating portion 30 , it is only necessary to insert a finger or the like through the gap between the support pieces 26 and 26 and push them upward.

  Moreover, between each support piece 26 and 26, the press part 32a which can be approached from the upper side is arrange | positioned. As shown in FIG. 3, the pressing portions 32 a are configured such that each pressing portion 32 a protrudes outward from the insertion hole 20 a portion provided in the support plate 20. Since these pressing parts 32a, 32a,... Move up and down in the vertical direction, it goes without saying that the insertion holes 20a, 20a,.

  The lever 34 is disposed above the intermediate plate 32. The lever 34 is attached to be rotatable in the direction of the arrow in FIG. When the lever 34 is rotated in the direction of the arrow, the tip end portion 34a of the lever 34 comes into contact with the upper end surface of the intermediate plate 32, and the intermediate plate 32 is pushed down as shown in FIG. When the intermediate plate 32 is pushed down, the pressing portion 32a enters between the support pieces 26 and 26, and presses each of the electrode 22 and the insulator 24 stacked in the accommodating portion 30 downward, and at the same time, each lead. The line 42 is clamped.

  In this embodiment, SUS material is used for the electrode 22, Teflon (registered trademark) material is used for the insulator 24, and Viton rubber is used for the elastic member 28, but each material used for the electrode 22, the insulator 24, and the elastic member 28 is used. If the material selection is made such that the elastic coefficient of the electrode 22, the insulating member 24, and the elastic member 28 become smaller in order, the electrode 22, the insulator 24, and the elastic member employed in the present embodiment. It is not limited to the combination of 28 materials.

Next, a method for plating the lead wire portion of the glass terminal will be described.
As shown in FIG. 2, the glass terminals 40 to be plated in the present embodiment are arranged at a required interval so that the lead wires 42 are symmetrical with respect to the end face of the eyelet 44 of the glass terminals 40. is there.
First, the glass terminals 40, 40,... Are disposed between the support pieces 26 of the support plate 20 in the plating rack 10. The electrode 22 and the insulator 24 are formed in an elongated round bar shape, and are simply stacked on the receiving portion 30 of the support piece 26. Accordingly, as shown in FIG. 3, if the lead wire 42 of the glass terminal 40 is inserted into the intermediate portion between the electrode 22 and the insulator 24, the outer diameter of the lead wire 42 is approximately the same as that between the electrode 22 and the insulator 24. A gap is generated. When the glass terminal 40 is further pressed toward the support plate 20, the lead wire 42 enters the gap and the lead wire 42 is sandwiched between the electrode 22 and the insulator 24.
Further, the lead wire 42 is simply inserted until the tip end portion of the lead wire 42 comes into contact with the support plate 20, and the amount of insertion of the lead wire 42 between the electrode 22 and the insulator 24 is uniform in all the glass terminals 40. Will be aligned.

  .. Of the plating rack 10 after the glass terminals 20 are disposed at the necessary positions, the lever 34 is rotated as shown in FIG. When the lever 34 is rotated, the tip 34a of the lever 34 abuts against the intermediate plate 32 as shown in FIG. 6, and pushes the intermediate plate 32 downward. At the same time, the pressing portions 32a, 32a,... Formed integrally with the intermediate plate 32 enter the housing portion 30 of the support piece 26 from above. When the lever 34 is rotated to a predetermined position, as shown in FIG. 5, the pressing portion 32 a presses the electrode 22, the lead wire 42, the insulator 24, and the elastic member 28 with a required pressing force. The lead wire 42 is sandwiched between an electrode 22 made of a material harder than the lead wire 42 such as stainless steel and an insulator 24 made of a material softer than the lead wire 42 such as Teflon (registered trademark). Thus, the elastic member 28 is pressed against the support surface of the support piece 26.

  The elastic member 28 is made of a material that is more flexible than the insulator 24. Therefore, when the pressing force by the pressing portion 32 is applied, the elastic member 28 is deformed as shown in FIG. 6 to relieve the pressing force that is applied to the lead wire 42. Thus, damage to the lead wires 42 can be prevented, and power can be supplied to the lead wires 42 while holding the lead wires 42 with an equal force, so that the electrolytic plating process on the lead wires 42 can be made uniform.

  The plating rack 10 is put into a plating solution supply tank (not shown) and the lead wire 42 is subjected to electrolytic plating treatment, and then the plating rack 10 is taken out from the plating solution supply tank. As shown in FIG. 1, the lever 34 is returned to the original position, and the pressure on the electrode 22, the lead wire 42, the insulator 24, and the elastic member 28 disposed in the accommodating portion 30 of the support piece 26 is released. If the pressing force by the pressing portion 32 is released, the glass terminal 40 can be easily pulled out from the plating rack 10. The drawn glass terminal 40 cuts a portion of the lead wire 42 that has been in contact with the electrode 22 and peels the plated metal adhering to components other than the lead wire 42 with a stripping solution or the like, thereby forming a product. As described above, the position where the lead wire 42 is in contact with the electrode 22 is the same position for all the glass terminals 40. Since it is only necessary to cut at the required position, it is possible to omit troublesome indexing work of the cutting position.

It goes without saying that the plating rack 10 and the glass terminal plating method according to the present invention are not limited to the above embodiments.
For example, in the above embodiment, the lead wires 42 of the glass terminals 40 arranged in the plating rack 10 are all the same number, but as shown in FIG. The glass terminal 40 having the above can be plated at the same time. However, in the glass terminals 40 that can be plated at the same time, the lead wires 42 are symmetrical with respect to the eyelet 44, and the arrangement intervals of the lead wires 42 are substantially the same in each glass terminal 40. It is limited to what is.
In addition, about the glass terminal 40 in which arrangement | positioning of the lead wire 42 is not left-right symmetric or the arrangement | positioning space | interval of the lead wire 42 differs, it can respond by changing the diameter size of the round bar of the electrode 22 and the insulator 24. It is.

  Moreover, in the said embodiment, although plating of the glass terminal 40 which has the five lead wires 42 was demonstrated, the electrode 22 arrange | positioned in the channel | path part 30 of the support piece 26, the diameter size of the insulator 24, and the number of stacking steps By adjusting this, it is possible to quickly cope with the number of lead wires 42 attached to the glass terminal 40. That is, since the changeover of the plating rack 10 in the case of plating different types of products is greatly simplified, an efficient plating process can be performed even in the case of a plating process of a large variety of small lots. At the same time, it is of course possible to arrange a plurality of types of glass terminals 40, each having a different arrangement state of the lead wires 42, in the same plating rack 10 and perform the plating process simultaneously.

  Further, as shown in FIG. 8, if the holding portion 50 for holding the glass terminal 40 is extended and attached in a direction away from the support plate 20, the lead wire 42 of the glass terminal 40 is connected to the gap between the electrode 22 and the insulator 24. Even in a state where the glass terminal 40 is just inserted into the portion, the glass terminal 40 is not dropped from the plating rack 10, which is preferable. Furthermore, if the holding | maintenance part 50 formed in the shape fitted to the external shape of the eyelet 44 of the glass terminal 40 is employ | adopted, the glass terminal 40 can be hold | maintained more suitably and the glass terminal 40 can be arrange | positioned. It becomes possible.

In addition, each of the electrode 22, the insulator 24, and the elastic member 28 is not necessarily formed in an elongated round bar shape. For example, the electrode 22 and the insulator 24 may be formed in the shape of an elongated rectangular bar or an elongated sheet, and the elastic member 28 is a sheet having a required thickness. It is also possible to adopt a form in which only the support surface is provided.
Further, the pressing portion 32a may not be provided separately between the support pieces 26 and 26, and may be a thin plate-shaped pressing portion that is formed in a shape that can enter the housing portion 30, and is directly or directly on the lever 34. Of course, it is also possible to adopt a form of connection via a link mechanism.

  Furthermore, as shown in FIG. 9, the electrode 22 formed in the shape which can contact each of the lead wire 42 attached to the glass terminal 40, and the insulator which can be fitted to the electrode 22 formed in this way It is also possible to adopt 24. At this time, if the insulator 24 is made of a material having an elastic coefficient comparable to that of the elastic member 28, the arrangement of the elastic member 28 can be omitted. By adopting the above configuration, it is possible to perform an electrolytic plating process on the lead wire 42 of the glass terminal 40 with the same quality as the present embodiment.

  Furthermore, as shown in FIG. 9, if the recess 22 a is formed at the position where the lead wire 42 of the electrode 22 is disposed, the positioning work on the lead wire 42 is simplified and the pressing by the pressing portion 32 is performed. In some cases, damage to the lead wire 42 can be prevented. In FIG. 9, the recess is formed only on the electrode 22, but it is of course possible to form a recess on the insulator 24 side, or to form a recess on both the electrode 22 and the insulator 24. .
