Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a structure of a winding frame with a pin terminal for an inductance element, particularly a winding frame used for an inductance element mounted on a substrate.

[Conventional technology]

As shown in FIG. 3 and FIG. 4, a winding frame conventionally used for an inductance element has a flange 2 at the left end and a flange 2'at the right end, which project outward from both left and right ends of a cylindrical winding core 1. An intermediate collar 3 protruding from the center of the winding core was molded with an insulating material. Terminal mounting portions 4, 4'are formed on the upper surfaces of the left and right collars 2, 2 ', respectively, and the winding 1
A plurality of pin terminals 5 for connecting lead wires 1 and 11 '
5'is implanted and grooves 6, 6'for guiding the lead wire of the winding are provided between the pin terminals. The lead wire is entangled with the pin terminals 5, 5'through the lead wire drawing grooves 6, 6'and then soldered, and then one leg of the E-shaped or U-shaped magnetic core 10, 10 'is attached to the winding core 1 from the left and right. It passes through the center hole 9 of each of the
Insulating tape is wound from above 0 and 10 'to form an inductance element.

[Problems to be solved by the invention]

However, the conventional reel of this type has a lead wire pulling groove 6,
If the number of 6's is less than the number of pin terminals 5, 5'and the lead wires of the windings 11, 11 'become thicker, they will stick out from the lead wire drawing grooves 6, 6'and come into contact with adjacent lead wires, resulting in poor insulation. There was a risk of causing. The present invention was devised to eliminate the above problems.

[Means for solving problems]

According to the present invention, the terminal mounting portions are provided on the upper surfaces of the left and right flanges of the winding frame made of an insulating material having the flanges protruding outward at the left and right ends and the central portion of the tubular winding core. In a pin terminal winding frame in which a plurality of pin terminals are planted in the left and right terminal mounting portions, and a groove for drawing out a lead wire of a winding is provided on the upper side of the left and right flanges, on the upper surface of the left and right flanges, The terminal mounting portion and the ridge portion are respectively provided, and the ridge portion is formed at the inner edge of the upper surface of the collar one step higher than the terminal mounting portion, and the groove is formed in the ridge portion and the pin terminal. A bobbin with a pin terminal is obtained in which the same number is formed.

[Action]

In the case of the present invention, since the groove is formed in the protruding portion which is one step higher than the pin terminal mounting portion, the lead wire does not jump out of the groove and the adjacent lead wires do not come into contact with each other.

〔Example〕

FIG. 1 is a perspective view showing an embodiment of a bobbin with pin terminals according to the present invention, and FIG. 2 is a rear view of the same embodiment.

1 and 2, this pin terminal winding frame comprises a winding core 1 and a plurality of pin terminals 5, 5 '. The core 1 is
It is made of insulating material and has a cylindrical shape. Collars 2 and 2'are formed at both left and right ends of the winding core 1, and an intermediate collar 3 is formed at the center thereof.
Are formed. The collars 2 and 2'at both left and right ends are provided with a central hole 9 having a size into which one leg of an E-shaped or U-shaped magnetic core 10 or 10 'shown by a chain line can be fitted. Further, on the upper surfaces of the collars 2 and 2'at both left and right ends, the terminal mounting portions 4 and
4'and ridges 41, 41 'are provided. Six pin terminals 5 and 5'are planted on the upper surfaces of the terminal mounting portions 4 and 4 ', respectively. The protrusions 41, 41 'are formed on the inner edges of the upper surfaces of the collars 2, 2'to be higher than the terminal mounting portions 4, 4'. On the protruding portions 41, 41 ', lead wire drawing grooves 6, 6'are provided corresponding to the pin terminals 5, 5'as many as the pin terminals 5, 5'. Therefore, the protrusions 41, 41 'have a substantially comb shape. The lead wire pull-out grooves 6 and 6 ′ are the windings 11 and 1 indicated by the one-dot chain line.
The lead wire 1'is guided to the pin terminals 5 and 5 '.
The lead wire pull-out grooves 6 and 6'are the protrusions 41 and 41 '.
Since the pin terminals are attached to the pin terminal attachment portions 4 and 4 ', the pin terminal attachment portions 4 and 4'protrude from the flange terminal attachment portion bottom surfaces 7 and 7', thereby providing a guide for preventing contact between adjacent lead wires. Standoffs 8 and 8'are formed at both ends of the protrusions 41 and 41 '.

The pin terminal winding frame having the above structure has the same number of lead wire drawing grooves 6, 6'and the same number of pin terminals 5, 5 ', and even if the lead wires of the windings 11, 11' are thick. ,
The lead wire pull-out grooves 6, 6'are the pin terminal mounting portions 4,
Since it is formed at a position higher than 4 ', the lead wire does not jump out from the lead wire drawing grooves 6, 6'.

[Effect of device]

According to the present invention, since the groove is formed in the ridge portion which is one step higher than the terminal mounting portion, the lead wire can be reliably held by this groove, and the contact between adjacent lead wires can be surely prevented.

Further, in the present invention, since the groove is formed in the protruding portion which is one step higher than the terminal mounting portion, even if the lead wire becomes thick, the lead wire does not jump out from the groove unlike the conventional case.
