Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a connection terminal provided with an element such as a backflow prevention diode or a flywheel diode, which is connected to a control circuit, for example.

Conventionally, the structure shown in FIG. 1 has been used when connecting a backflow prevention diode or the like to a control relay or the like.

In the figure, 1 is a diode, 2 is a tube placed over the diode 1, 3 is a crimp terminal, 4 is a connecting wire, 5 is a terminal block for fixing the diode 1, and 6 is a control relay.

6a is one contact of the control relay 6.

In this way, in order to insert the diode 1 into the contact 6a of the control relay 6, in the conventional system, a terminal block 5 is provided, and the diode 1 covered with the tube 2 is connected with the crimp terminal 3. and a control relay 6 are connected by an electric wire 4.

However, such a conventional configuration has disadvantages in that it requires a large insertion space, requires a large number of parts, and has many connection points.

This invention was made to eliminate the above-mentioned drawbacks, and by giving the crimp terminal the function of a terminal block, it was possible to insert and attach a diode and connect electric wires at the same time.

An embodiment of this invention will be described below with reference to the drawings.

In FIGS. 3 to 5, reference numeral 7 denotes the connection terminal of this invention, which is comprised of an insulating tube 9 with its upper half open and metal tubes 8a and 8b fitted into the front and rear ends of the insulating tube 9.

The metal cylinder 8a is provided with a screw tightening tongue.

10 is a protrusion for positioning the diode 1. The diode 1 is inserted from the half-open part of the insulating cylinder 9 using the protrusion 10 as a guide, and one of its leads is crimped with the metal cylindrical part 8a, and the other is crimped with the metal cylindrical part 8b, and the connecting wire 4
connected to.

If the same sequence as that shown in FIG. 2 showing the circuit configuration of FIG. 1 is constructed using the terminals of the present invention, the result will be as shown in FIG. 6.

Comparing this with the conventional one shown in Figure 1, the one of the present invention does not have a terminal block, but the connecting terminal functions as a crimp terminal for connection and a terminal block, holds the diode, and is integrated with the connecting wire. connected.

Therefore, the present invention has the advantage that a large space is not required for inserting the diode, the number of required parts is small, and the number of connection points is small.

In the above embodiment, one of the metal tubes is a metal tube 8a having a screw tightening tongue, but both ends may be made of a metal tube 8b as shown in FIG.

Alternatively, both ends may be made into metal tubes 8a for the purpose of holding and connecting the diode 1.

Further, 1 is not limited to a diode, but may be any other element, and the control relay 6 may be of another type.

FIG. 8 shows an example in which a code piece 11 is wrapped around a diode 1 to indicate polarity.

As is clear from the above explanation, this invention eliminates the need for a terminal block to connect elements, has fewer connection points, and can be inserted near the connected circuit or equipment, resulting in low cost and high connection quality. You can get the equipment.

When inserting an element into a circuit for the purpose of surge prevention or the like, the element can be inserted directly and close to the required circuit, so the element's functions can be more fully demonstrated than in conventional devices.
