JPH08213256A - Wire-bundle terminal - Google Patents

Abstract

PURPOSE: To provide a wire-bundle terminal which can be connected and fixed at one touch without causing a wire to slack after binding or disconnection during bundling operation in a transformer with the wire-bundle terminal. CONSTITUTION: A cutting wire 5a is formed at the loose terminal portion of a wire-bundle terminal 5 extended from a transformer and a wire is inserted into the cutting wire 5a for clamping retention.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire barb terminal which is improved in workability when the wire bar is fixed to a barbed terminal extending from a component such as a transformer mounted on a printed circuit board.

[0002]

2. Description of the Related Art A mounted component such as a transformer arranged on a printed circuit board has a through-hole insertion terminal projecting from the bottom surface or side surface of the transformer body and a terminal for reflow connection on a wiring pattern. In addition to these terminals, terminals called winding winding terminals are provided. FIG.
(a) and (b) are the structural explanatory drawing and the partially enlarged view of the conventional transformer provided with the twisting terminal, this transformer is the transformer main body 1 which consists of the bobbin 2 and the terminal supporting portion 3, and the terminal supporting portion. Through-hole insertion terminal 4 protruding from the lower surface of 3
And a barbed terminal 5 horizontally projected from the side wall of the terminal support portion 3.

When the winding 6 is fixed to the cord terminal 5, as shown in the figure, the winding 6 is twisted on the thin rod-shaped cord terminal 3 at least three times and then immersed in a solder bath to be fixed. ing. However, when the winding is fixed by this method, not only the looseness after the tangling occurs when the thick wire is used, but also the breakage occurs easily during the tangling work when the thin wire is used. In addition, when the number of twisting terminals is large, the number of twisting steps is increased and the workability is deteriorated.

SUMMARY OF THE INVENTION The present invention has been made in view of the above, and in a transformer provided with a tangling terminal, one-touch operation without causing slackening of the wire after tangling or disconnection during tangling work. The purpose is to provide a barbed terminal that can be connected and fixed in place.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention is to form a cut line at a free end of a barbed terminal extending from a component for mounting a printed circuit board such as a transformer, and insert a wire into the cut line to squeeze the wire. It is characterized in that it can be held.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in detail below with reference to the embodiments shown in the accompanying drawings. FIG. 1 is an explanatory view showing the outer appearance of an embodiment of a transformer to which the present invention is applied, and FIGS. 2 (a) (b) and (c)
FIG. 3 is a perspective view showing a configuration of a main part of the embodiment of FIG. 1, a plan view and a perspective view showing a mounting state, and this transformer is composed of a transformer main body 1 including a bobbin 2 and a terminal supporting portion 3, and a terminal supporting portion 3. Through-hole insertion terminal 4 protruding from the bottom surface
And a barbed terminal 5 horizontally projected from the side wall of the terminal support portion 3.

The barb terminal 5, which is horizontally led out from the side portion of the terminal support portion 3, has a notch line 5a extending in the longitudinal direction at the center of the tip end thereof. Can be opened and closed elastically. Using this elasticity, the wire rod 6 is press-fitted into the scored wire 5a for temporary fixing (FIG. 2 (c)), and in this state, the barb terminal 5 and the wire rod 6 are immersed in the solder bath to complete the fixing. .

FIG. 3 is a diagram showing an example in which the cord terminal of the present invention is applied to another type of transformer. The barbed terminal of the present invention can be applied not only to the through-hole insertion type transformer as shown but also to a surface mounting transformer.

[0009]

As described above, according to the present invention, a notch line is formed at the free end of a barb terminal extending from a printed circuit board mounting component such as a transformer, and a winding is inserted into the notch line to hold a pinching force. Since the wire rod is configured to be capable of being twisted, it is possible to connect and fix (temporarily fix) the wire rod to the cord terminal with one touch without slackening of the wire rod after the twisting or disconnection during the peeling work.
