An electric component unit to be improved by the present invention is characterized in that a part to be fitted is fitted into a fitting groove for terminal mounting formed in a terminal fitting mounting part of an insulating resin case. And a terminal fitting for lead wire connection fixed to the terminal fitting mounting portion. The lead wire connecting terminal fitting is formed by machining a metal plate, and is formed integrally with the fitted portion and connected to a lead wire extending from an electric component housed in the case and connected thereto. It has a wire connection part and a terminal part electrically connected to an electric component outside the case. For example, in an electric component unit such as a high-voltage variable resistor, the insulating resin case has an opening on one surface and a terminal fitting mounting portion around the opening. The terminal fitting groove formed in the terminal fitting mounting portion is perpendicular to the opening direction of the case, the direction toward the opening of the case, and the direction from the opening to the outside of the case. And open to each.

According to the present invention, the lead wire connecting portion of the lead wire connecting terminal has a lead wire insertion opening having a width dimension larger than the diameter of the core wire of the lead wire and a width dimension greater than the diameter of the core wire of the lead wire. A lead wire press-fitting groove which is small and is formed continuously with the lead wire insertion opening and into which the core wire of the lead wire is press-fitted is formed. Then, the lead wire is connected to the lead wire connection portion in a state where the lead wire is simply pressed into the lead wire press-fitting groove.

With such a structure, the lead wire can be fixed and the electrical connection to the terminal fitting can be made simply by inserting the core wire of the lead wire into the lead wire insertion opening and moving the lead wire into the lead wire press-fitting groove. Since the connection and the connection can be completed at the same time, the automation is easy and the connection work is simplified. In particular, when a plurality of projections that bite into the core of the lead wire are provided on a pair of opposing walls of the lead wire press-fitting groove, the fixation and connection of the lead wire are further ensured. Further, when the lead wire insertion opening is formed so as to open outward, it becomes easy to insert the lead wire into the lead wire insertion opening.

In the lead wire connecting terminal fitting, the lead wire connecting portion and the terminal portion extend in a direction substantially orthogonal to each other from the fitted portion, and the lead wire connecting portion, the fitted portion and the terminal portion are planar. Can be formed in a line. In this case,
The terminal fitting mounting part has a protruding part that protrudes from the case,
The terminal mounting fitting grooves are formed so as to open in the direction in which the protruding portion protrudes and in the direction orthogonal to the direction and away from each other. Then, the lead wire connecting terminal fitting is arranged so that the lead wire connecting portion of the lead wire connecting terminal fitting extends from the opening that opens in the direction in which the protrusion of the terminal fitting fitting groove projects. In this manner, when a plurality of lead wire connecting terminal fittings are arranged side by side, each lead wire connecting terminal fitting can be placed in an upright state, and an advantage that the installation space can be reduced can be obtained.

The length of the lead wire press-fitting groove can be sufficiently ensured.
In particular, if the core of the lead wire is lowered to the end of the lead wire press-fitting groove, the fixing and connection of the lead wire can be further ensured.

Further, when the terminal portion of the lead wire connecting terminal fitting is formed by rolling a part of a metal plate into a cylindrical shape, the mechanical strength of the terminal portion is increased. In this case, the fitted portion may be formed in a cylindrical shape.

In the case where a thin metal plate is processed to form a lead connection terminal fitting, further processing is required to increase mechanical strength. However, if the metal lead (for example, a stainless steel plate) having a thickness of 0.7 mm or more is used to form the terminal fitting for connecting lead wires, it is not necessary to perform a special process for increasing the mechanical strength.

[0014] Further, the terminal fitting is inserted into the lead wire connecting terminal fitting from the opening on the other end side of the fitting groove for terminal attachment toward the opening on one end side for a predetermined length. It is preferable that a contact piece that comes into contact with a stopper surface provided on the metal fitting mounting portion be provided integrally. With this configuration, it is possible to prevent the fitting portion of the lead wire connecting terminal fitting from being excessively pushed into the terminal mounting fitting groove, and to facilitate automatic insertion of the lead wire connecting terminal fitting. Such a contact piece may be provided integrally with the lead wire connection terminal fitting so as to be adjacent to the base of the terminal portion of the lead wire connection terminal fitting and extend in a direction orthogonal to the direction in which the terminal portion extends. it can.

In the case of the case having the above-mentioned opening, it is preferable to provide the terminal fitting engaged portion outside the opening at one end of the terminal mounting fitting groove located on the opening side of the case.

In the fitting portion of the terminal fitting for lead wire connection, the fitting portion is inserted from the opening at the other end of the fitting groove for terminal attachment toward the opening at one end. In the completed state, an engaging projection that engages with the terminal fitting engaged portion can be provided integrally. The engagement projection allows the fitted portion to be inserted from the opening on the other end side of the fitting groove for terminal attachment toward the opening on one end side. The connection terminal fitting may have such a shape that the engagement with the terminal fitting engagement part cannot be released when a pulling force in a direction from the opening on one end side toward the opening on the other end side is applied to the connection terminal fitting. preferable. The terminal portion extends toward the outside of the case in a state where the fitted portion of the lead wire connecting terminal fitting is fitted in the fitting groove for terminal attachment. With such a configuration, the lead wire connection terminal fitting can be easily attached to the case simply by inserting the fitted portion of the lead wire connection terminal fitting into the terminal attachment fitting groove provided on the case side from the outside of the case. Can be mounted on

In particular, in the case of using the above-described one-sided opening case, the terminal fitting groove is formed in such a manner that the direction in which the opening of the case is opened, the direction orthogonal to the direction, and the direction toward the opening of the case are different. The opening is made in the direction from the opening to the outside of the case. And lead wire connection terminal fittings,
The lead wire connecting portion and the terminal portion are formed so as to extend from the fitted portion in directions substantially orthogonal to each other, and the lead wire connecting portion, the fitted portion and the terminal portion are arranged in a plane. With this configuration, in a state where the fitting portion of the lead wire connection terminal fitting is completely fitted into the fitting groove for terminal attachment, the terminal portion extends outwardly away from the opening of the case. In addition, the lead wire connecting portion extends from the opening that opens in the direction in which the opening of the case of the terminal fitting fitting groove opens. In other words, in a state where the fitting portion of the lead wire connecting terminal fitting is set up (the fitting portion of the lead wire connecting terminal fitting and the lead wire connecting portion extend in a direction orthogonal to the opening surface of the opening of the case). The terminal fitting for connecting the lead wire can be fixed to the case. Therefore, the mounting space for the lead wire connecting terminal fittings is reduced, the unit can be made compact, and more lead wire connecting terminal fittings can be mounted than before. In addition, such an effect
A protrusion protruding from the case is provided in the terminal fitting mounting portion, and the terminal mounting fitting groove is formed so as to open in a direction in which the protrusion protrudes and in a direction perpendicular to the direction and away from each other. The same can be obtained by fitting the fitted portion of the lead wire connecting terminal fitting into the fitting groove for fitting.
