Abstract

PROBLEM TO BE SOLVED: To easily and securely fit a terminal to a terminal plate by extending a stopper under the fitting part in a horizontal direction and allowing the upper part of the stopper to be brought into contact with the lower part of the fitting part. SOLUTION: A terminal 1 is provided with an engaging part 1b protruding to the side on its upper part, and the part 1b is brought into contact with the upper end of a fitting part 2b for positioning. In addition, a stopper 1c of the terminal 1 is bent to the projecting direction of the fitting part 2d, crossing orthogonally the terminal body in lengthwise direction when the terminal is inserted. Then the stopper 1c is inserted between a pair of fitting parts 2d, and a part thereof appearing under the lower position of the part 2d is extending in a horizontal direction. The upper part of the stopper 1c is tilt and tapered from the upper side to lower side, and it is brought into contact with the lower end of the fitting part 2d. Such a tapered shape generates wedge effect, eliminating any loaseness after caulking and fitting a terminal securely.

In FIG. 1, reference numeral 1 is a flat terminal made of a conductive member. A lead wire connecting portion 1a is formed at the center of the upper end of the terminal 1. In addition, a locking portion 1b that projects laterally is formed on the upper portion, and a retaining portion 1c is formed at a separated position below the locking portion 1b. further,
Below the terminal 1, more specifically, the lead wires 4a, 4 shown in FIG.
A holding portion 1d for guiding and receiving b is formed. The enclosing portion 1d is formed by making cuts on both lower sides and bending both sides outward in a substantially arc shape as shown in FIG.

In FIG. 1, reference numeral 2 is a terminal plate made of an insulating resin and having a substantially rectangular shape as a whole. An engaging window 2a that engages with an engaging portion 6c of a terminal plate attaching portion 6b shown in FIG. 5 described later in detail is formed above the center of the terminal plate 2. In addition, the lower opening 2 is provided inside the terminal board 2.
A recess 2c is formed for inserting the terminal plate mounting portion 6b through b.

Further, a mounting portion 2d for mounting the terminal 1 is formed on the outer surface of the terminal plate 2. Each of the mounting portions 2d is composed of a pair of protrusions protruding outward,
The terminal 1 is inserted from above into the root portion thereof. On the upper part of the terminal 1, as described above, the locking portion 1b which is laterally projected.
The locking portion 1b contacts the upper end of the mounting portion 2d and is positioned. When the terminal is inserted, the retaining portion 1c of the terminal 1 is bent in the protruding direction of the attaching portion 2d substantially orthogonal to the long terminal body, and is inserted between the pair of attaching portions 2d to come out to the lower position. By the way, as shown in FIG.
The terminal 1 is prevented from slipping out by being pushed out in the lateral direction.

FIG. 3 shows the mounting state of the terminal 1, and FIG. 4 shows A in FIG.
In the enlarged view of the portion, the upper portion of the retaining portion 1c has a tapered shape that inclines downward from above, and abuts on the lower end of the mounting portion 2d. In this way, the taper shape provides a wedge effect, which eliminates backlash after crimping and enables reliable fixation.

Incidentally, as shown in detail in FIG. 4, both side portions 1c 'of the retaining portion 1c are bent and reinforced.

FIG. 5 shows a state in which the terminal plate 2 to which the terminal 1 is attached is attached to the reactor main body 3.

In FIG. 5, 4 is a coil formed by winding a thick wire (for example, 1.5 mm) on the body of the coil bobbin, and 5 is an EI type formed by laminating silicon steel plates incorporated in the coil bobbin. Core, 6 has the above-mentioned assembly attached,
A mounting plate made of a metal plate such as an iron plate and having a mounting hole 6a, and a terminal plate mounting portion 6b formed by bending a part of the mounting plate 6 upward at a substantially right angle. .

Ribs 6c are formed and reinforced on the terminal plate mounting portion 6b, and the terminal plate 2 having the terminals 1 is mounted on the ribs 6c. Prior to this, the lead wires 4a at the beginning and end of the coil 4 are wound. , 4b are formed in a predetermined shape in advance, and when the terminal plate 2 is attached to the terminal plate attachment portion 6b, the lead lines 4a, 4b are guided and held by the holding portion 1d of the terminal 1. Has become.

That is, since each of the lead wires 4a and 4b is formed of a thick wire, the lead wire is flexible and can be bent due to its material and can be formed into a predetermined shape. In this forming, the lead wires 4a and 4b are cut into a predetermined length, the surrounding insulating film is removed, and the lead wires are bent into a predetermined shape. The forming work may be performed manually or may be performed automatically through a robot.

A tongue-shaped engaging portion 6d formed by punching is formed on the upper portion of the terminal plate mounting portion 6b. The engaging portion 6d is bent slightly outward, and the terminal plate mounting portion 6b is formed in the recess 2c formed inside the terminal plate 2 and the lower opening 2b is formed.
Since the engaging portion 6d has elasticity due to the material when it is inserted through and is attached through, the pressed state is released when the tip reaches the position of the lower edge 2a 'of the engaging window 2a. Therefore, it is possible to prevent the terminal plate 2 from coming off by returning to the outer position and engaging the tip with the lower edge 2a 'of the engagement window 2a.

At this point in time, the holding portion 1d and each lead wire 4
a and 4b are contacted. This contact portion is soldered and connected as is well known. In this case, solder easily rides on the outer upper portion of the holding portion 1d due to its shape.

After that, the insulating cover 7 is attached to the terminal board 2. A pair of arms 7a are projectingly provided on both sides of the insulating cover 7, and an engaging portion 7b bent inward is formed at the tip of the arm 7a.
The insulating cover 7 is attached to the terminal board 2 by engaging with the step portion 2d 'at the base of the side portion of d.

A pair of mounting portions 2 arranged side by side, respectively.
The inner part of d has a protrusion 2e, and the protrusion 2e is formed on the window 7 formed at a corresponding position of the insulating cover 7.
c.

FIG. 6 is an external perspective view of a state in which the assembly is completed.

[0022]

As described above, according to the present invention, the terminal 1
The terminal 1 is easily and surely inserted by inserting the terminal plate 2 between the pair of mounting portions 2d of the terminal plate 2 until it is positioned, and simply expanding the retaining portion 1c protruding downward in the lateral direction. Can be attached to 2. Further, since the upper portion of the retaining portion 1c has a tapered shape,
A so-called wedge effect can prevent rattling.
