端子部24が形成されている。BACKGROUND ART FIG. 5 is a perspective view showing a configuration of an electric device such as an electromagnetic switch. Medium-sized container 20 with the functional parts of electrical equipment inside
Are housed and protected in the space formed by the case 21 and the lid 22. The case 21 is formed with a terminal portion 24 to which a plurality of terminals 23 for supplying operating power to the functional component and outputting signals are attached.
従来のケース21の端子部24は、第６図に示すような構造

て外部配線の接続が正しく行なわれるように工夫されて
いるが、この従来例では、ケース21の外部から端子23に
正しくリード線27が固着されているか確認することがで
きない。The terminal portion 24 of the conventional case 21 has a structure as shown in FIG. That is, openings 25 and 26 are formed in the terminal portion 24, and the lead wire connection portion 23a and the fitting portion 23b of the terminal 23 are fitted into the openings 25 and 26, respectively. Therefore, when fixing the end portion 27a of the lead wire 27 to the lead wire connecting portion 23a of the terminal 23, with the terminal 23 fitted in the case 21, insert the tip of the soldering iron inside the case 21. You have to do that work. Therefore, not only the workability is very poor, but also the work failure is likely to occur. In addition, since there are multiple terminals 23, it has been devised so that the external wiring can be connected correctly by coloring it, but in this conventional example, the lead wire 27 is correctly fixed to the terminal 23 from the outside of the case 21. I can't confirm whether.
この考案の目的は、従来例の問題点の解消を図り、リー
ド線の接続が容易で、しかもリード線の被覆色をケース
の外部から確認することができる電気機器ケースの端子
部構造を提供することである。An object of the present invention is to solve the problems of the conventional example, to provide a terminal portion structure of an electric device case in which lead wires can be easily connected and the coating color of the lead wires can be confirmed from the outside of the case. That is.
この考案の電気機器ケースの端子部構造は、逆Ｕ字形で

が前記挿入溝に位置するようにしたものである。The terminal part structure of the electric equipment case of the present invention is an inverted U-shaped terminal having one end piece as a lead wire connecting part and a terminal screw hole in the middle part, and an end part on the outer surface of the lead wire connecting part. A lead wire connected to the terminal; and a case having a pair of openings for fitting both end pieces of the terminal and an insertion groove into which the lead wire fits is formed at an edge of the opening, the both end pieces being the opening. The end portion of the lead wire is positioned in the insertion groove in a state of being fitted in the portion.
この考案によれば、つぎの作用がある。According to this invention, there are the following effects.

入する危険性もない。Pull the lead wire out from the inside of the case through the insertion groove of the opening, connect the end of the lead wire to the lead wire connection part of the terminal, and then insert the lead wire and the lead wire connection part of the terminal into the opening part. Since the lead wire is easily connected, the coating color of the lead wire can be confirmed from the outside through the insertion groove without deteriorating the appearance of the lead wire. Moreover, the terminals are formed in an inverted U shape,
Since the both end pieces are fitted into the pair of openings and the terminal screw is tightened through the terminal screw hole, the terminal can be easily attached. Also, since the lead wire fits in the insertion groove and both ends of the terminal fit in the opening, the inside cannot be seen through the insertion groove and the opening, and there is no risk of foreign matter entering. .

を第４図に示す。Embodiment An embodiment of the present invention will be described with reference to FIGS. 1 and 2 are perspective views showing the structure of one embodiment, FIG. 3 is a view of a terminal 2 to which a lead wire 3 is fixed, as seen from the side, and FIG. It is a top view showing the state where terminal 2 was fitted in terminal part 1a. As shown in FIG. 1, the terminal portion 1a of the case 1 has one end piece and a lead wire connecting portion.
A pair of openings 1b, 1c into which both end pieces (2a, 2b) of the inverted U-shaped terminal 2 to be 2a are fitted are formed. Two insertion grooves 1d and 1e are formed on opposite sides of the opening 1b. The lead wire 3 is pulled out from the inside of the case 1 by inserting it through the insertion groove 1d of the opening 1b, and as shown in FIG. 3, the insertion hole 2c formed in the lead wire connecting portion 2a near the bent portion of the terminal 2. The end portion 3a is inserted from the outer surface and soldered to the back side of the lead wire connecting portion 2a. While pulling the lead wire 3 into the case 1, as shown in FIG. 2, the lead wire connecting portion of the terminal 2
When the 2a and the fitting portion 2b are fitted into the openings 1b and 1c, respectively, the lead wire 3 is inserted into the insertion groove 1d, and the fixing portion 3b to which the end portion 3a is soldered is inserted into the insertion groove 1e. This is shown in FIG.

張力などが加わりにくくなることや固着位置が固定され
るので半田付け作業がやりやすい利点もある。In this embodiment, as shown in FIG. 1, the end portion 3a of the lead wire 3 can be soldered outside the case 1. Further, as shown in FIG. 4, since the coating of the lead wire 3 can be seen from the insertion groove 1d, the coating color can be confirmed.
It is easy to inspect the connection state of the lead wire 3 by the color. Moreover, the lead wire 3 is not exposed to the outside so that the appearance is good. In addition, the terminal 2 is formed in an inverted U shape,
Since both end pieces (2a, 2b) are fitted in the pair of openings 1b, 1c and the terminal screw (not shown) is tightened through the terminal screw hole 4, the terminal 2 can be easily attached. Since the lead wire 3 is fitted in the insertion groove 1d and the lead wire connecting portion 2a of the terminal 2 is fitted in the opening 1b, the inside cannot be seen through the insertion groove 1d and the opening 1b. There is no risk of foreign matter entering. In addition, since the end portion 3a of the lead wire 3 is inserted into the insertion hole 2c of the terminal 2, it is difficult to apply a pulling force directly to the fixing portion 3b and the fixing position is fixed, so that the soldering work is performed easily. There is also an easy advantage.

る。According to this invention, the lead wire is pulled out from the inside of the case through the insertion groove of the opening, the end portion of the lead wire is connected to the lead wire connecting portion of the terminal, and then the lead wire and the lead wire connecting portion of the terminal are connected. Since I tried to fit it in the opening,
The lead wire can be easily connected and the coating color of the lead wire can be confirmed from the outside through the insertion groove without deteriorating the appearance of the lead wire. Moreover, since the terminal is formed in an inverted U shape and both end pieces thereof are fitted into the pair of openings and the terminal screw is tightened through the terminal screw hole, the terminal can be easily attached. Also, since the lead wire fits in the insertion groove and both ends of the terminal fit in the opening, the inside cannot be seen through the insertion groove and the opening, and there is no risk of foreign matter entering. There is an effect.
