Abstract

PURPOSE:To facilitate the insertion and fixation to a printed circuit board by providing such as constitution as covering the leg part of a U-shaped conduc tor with a U-shaped insulating material, and protruding only the leg part top end and clinch part of the conductor from the insulator. CONSTITUTION:When a connecting terminal is inserted and fixed to a printed circuit board 3, and leg parts 1a of a conductor 1 formed into U-shape are inserted to a printed circuit board 3, and soldered 5 to a conductor layer 4 on the lower surface of the printed circuit board 3. In this case, as the leg center part of the conductor 1 is covered with an insulator 2 having a U-shaped notch, the positional relation in the leg top end of the conductor 1 is precisely regulated, and the conductor can be easily inserted to the printed circuit board 3 by use of an automatic inserting machine.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to connection terminals used in television receivers, video tape recorders and other electrical equipment.

Prior Art In general, connection terminals attached to printed wiring boards are often formed in the form of strips, as shown in FIG. When inserting and fixing on a wiring board, a special jig or an automatic insertion machine is required, and when the number of connection terminals 7 used is small, there is a problem that the insertion cost per one becomes very high. Ta.

The present invention eliminates the above-mentioned conventional drawbacks and provides an excellent connection terminal that has a simple structure and is extremely easy to attach to a printed wiring board.

A further means of solving the problem is to cover the central part of the U-shaped conductive wire with an insulating material having a U-shaped notch and use it as the gripping area of the automatic insertion machine's stopper at both ends of the conductive layer. is exposed from the insulating material, and a space is provided in the U-shaped cut above the insulating material and the folded portion.

According to this configuration, the center part of the leg of the conductor is covered with an insulator, so the positional relationship at the tip of the leg of the conductor is accurately regulated, and printing can be easily performed using automatic insertion → etc. Can be inserted into the wiring board.

Further, since a space is formed between the folded portion of the conductor and the cut portion of the insulator, when this space is used as a test point for measurement, a clip or the like can be easily and accurately attached thereto.

Embodiment Hereinafter, a connection terminal of the present invention will be explained with reference to drawings of one embodiment. Figures 1 and 1 are a side view and a bottom view, respectively, of an embodiment of the connection terminal of the present invention, in which 1 is a conductor wire formed in a U shape, and 2 is a conductor wire with a U-shaped cut. 1 leg 1! This is an insulator that is integrally formed to cover the central part of L.

In the above embodiment, when inserting and fixing the connecting terminal into the printed wiring board, as shown in FIG.
, 11L' are inserted into the printed wiring board 3 and soldered 5 to the conductor layer 4 on the lower surface of the printed wiring board 3. In this case, according to the above embodiment, since the center part of the leg of the conductor 1 is covered with the insulator 2, the positional relationship at the tip of the leg of the conductor 1 is accurately regulated, and an automatic insertion machine etc. It can be easily inserted into the printed wiring board 3 by using the printed wiring board 3.

In addition, according to the above embodiment, since a space is formed between the folded part 1b of the conductor 1 and the notch part 21L of the insulator 2, when this is used as a test point for measurement, a clip or the like can be easily attached here. Can be installed accurately. In addition, when there is a limit on the height of components to be mounted on a printed wiring board, this connection terminal is extremely advantageous in that it minimizes the height while maintaining the holding strength between the conductor and the insulator and satisfies the above embodiments.

In the above embodiment, the conductor 2 is simply formed into a U shape and the insulator 2 covers the central part of the leg. However, as shown in FIGS. 3 and 4, the leg 1 of the conductor 1 is N, 1a
'It is also possible to form four terminals by extending the ends and fixing the extensions to the tape 6.6 to connect a plurality of connection terminals to each other. This configuration has the advantage that the connection terminal can be automatically inserted into the printed wiring board in the same way using an automatic insertion machine for taped resistors, etc., which is extremely advantageous in practice.

Effects of the Invention As is clear from the above description, the present invention uses a U-shaped conducting wire, the legs of which are covered with a U-shaped insulator, and only the tips and folded portions of the legs of the conducting wire protrude from one insulator. It can be easily inserted and fixed onto a printed wiring board without using a special jig or a special automatic insertion machine, and is extremely advantageous in practice. When used as a test point, it has the advantage of being low in height and can be used in a wide range of applications.
