Abstract

PURPOSE:To eliminate soldering or welding work and reduce the number of processes by continuing the terminal bobbin of a coil holding member to a connecting member by the insertion of a connector terminal to electrically connect both. CONSTITUTION:A U-shaped terminal bobbin 9 is integrally molded on a terminal bobbin solid part 20b and continued to a coil 6 in the coil continuing part 9a situated on one end thereof. A connector member 30 is integrally formed with a resin cap so as to expose both the ends of a L-shaped terminal male 10. The terminal bobbin solid part 20b has a fitting hole 20ba. The connector member 30 has an insert part 30a capable of being inserted into the fitting hole 20ba. Further, an engaging part 30b engaging with the wall surface of the terminal bobbin solid part 20b is extended on the connector member 30.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle pressure switching solenoid.

[0002]

2. Description of the Related Art Conventionally, as a conduction between a coupler terminal and a solenoid, a technique as shown in Japanese Utility Model Publication No. 2-45565 and FIG. 2 is known.

As shown in FIG. 2, the base 1 is an orifice 2
Has a built-in, and serves as a conduit for oil. Ball 3
Serves as a valve by opening and closing the orifice 2 of the base 1. The movable plunger 4 is pressed in the direction of the ball 3 by a spring 5.

Since the movable plunger 4 is a part of a magnetic circuit, the coil 6 is energized to overcome the repulsive force of the spring 5 in the direction of the facing stator core 7. Sliding, the ball 3
Moves to open the orifice 2 of the base 1. When the power supply is stopped, the repulsive force of the spring 5 causes the movable plunger 4 to return to its original position and the ball 3 to close the orifice 2 of the base 1.

The coil 6 is interposed in the bobbin 8 so as to establish electrical continuity with the coil 6 at a joint 109a which is one end of the L-shaped terminal bobbin 109.

Further, the other end 109b of the terminal bobbin 109 is joined to the terminal mail 110 which is integrally formed with the connector member.

Here, one end 10 of the terminal bobbin
9b and the terminal mail 110 are electrically connected by soldering or welding.

[0008]

A problem to be solved by the invention is that when conducting the soldering or welding as described above, the step of connecting the terminal mail and the terminal bobbin after assembling remains, resulting in the number of assembling steps. Not only does it take a lot of time, but it also requires advanced assembly technology.

[0009]

In order to solve the above-mentioned problems, a stator core around which a coil is wound, a movable plunger arranged facing the electromagnetically to and from the stator core, and a movable plunger interlocked with the movable plunger are interlocked. In a hydraulic solenoid having a valve member that opens and closes and is equipped with an electrically conductive connector member, the connector member is integrally formed with a connector resin so as to expose both ends of the terminal mail, and one end of the terminal mail is The coil holding member is inserted into one end of a U-shaped terminal bobbin so as to be electrically connected.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

In this embodiment, the present invention is applied to a hydraulic solenoid, and FIG. 1 is a sectional view of the hydraulic solenoid.

The basic function of the valve is the same as that described in the prior art and will not be repeated here.

The coil holding member 20 is composed of a bobbin 20a and a terminal bobbin fixing portion 20b, and a coil 6 is interposed in the bobbin 20a.

A U-shaped terminal bobbin 9 is integrally formed with the terminal bobbin fixing portion 20b, and is electrically connected to the coil 6 at a coil conducting portion 9a which is one end thereof.

Further, the terminal mail joint portion 9b, which is the other end of the U-shaped terminal bobbin 9, has a fitting hole for insertion in connection with the terminal mail 10 of the connector member 30 described later, and therefore has a cross section. The figure is U-shaped.

The connector member 30 is integrally formed with a resin cap such that the L-shaped terminal mail 10 is exposed at both ends.

A fitting hole 20ba is provided in the terminal bobbin fixing portion 20b. Further, the connector member 30 is provided with an insertion portion 30a that can be inserted into the fitting hole 20ba. Further, the connector member 30 is provided with an engaging portion 30b which engages with the wall surface (left side surface in FIG. 1) of the terminal bobbin fixing portion 20b.

Next, a method of assembling the connector member 30 to the coil holding member 20 in the hydraulic solenoid of this construction will be described.

The connector member 30 is assembled from the upper side of the terminal bobbin fixing portion 20b of the coil holding member 20. At this time, one end 10a of the terminal mail 10 is attached.
Is inserted into the terminal mail joining portion 9b, which is one end of the terminal bobbin 9, to electrically connect the terminal mail 10 and the terminal bobbin 9.

At the same time, the insertion portion 30a of the connector member 30
Is inserted into the fitting hole 20ba of the terminal bobbin fixing portion 20b, and the engaging portion 30b is inserted into the terminal bobbin fixing portion 2b.
0b, the connector member 30 and the terminal bobbin fixing portion 20b are fixedly mounted.

[0021]

According to the present invention, in order to electrically connect the connector member to the terminal bobbin of the coil holding member, the connector terminal is inserted to establish electrical continuity. Therefore, the soldering or welding work can be eliminated, and the man-hours can be reduced. In addition, costs can be reduced accordingly.

Further, the electric connection can be surely made by a simple assembling work, and the advanced soldering or welding technique is not required, so that the quality is stabilized.
