Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of use) The present invention relates to an improvement of a jack into which a plug is inserted for connection.

(Prior Art) In a conventional jack, a plug housing hole 2 is provided in a jack housing 1 made of an insulating material as shown in FIG.
A sleeve metal 3 is inserted into the inlet of the plug insertion hole 2, and a sleeve terminal 4 is connected and fixed to the sleeve metal 3 by caulking an inner end of a tubular portion 3a of the sleeve metal 3. The sleeve terminal 4 is provided with a plug contact portion 4a so as to face the plug insertion hole 2.

(Problems to be Solved by the Invention) In such a jack, caulking is required to connect the sleeve metal 3 and the sleeve terminal 4 to each other, so that there is a problem in that the assemblability is poor.

An object of the present invention is to provide a jack capable of fixing a sleeve metal to a jack housing without requiring crimping.

(Means for Solving the Problems) The structure of the present invention for achieving the above object will be described. In the present invention, the jack housing is provided with a plug insertion hole, and the plug insertion hole is arranged on the end side. A jack in which a sleeve metal, a flat-plate-shaped sleeve terminal inserted in the plug insertion hole, and a contact terminal arranged so as to face the spring connection portion in the plug insertion hole are incorporated. , A plug contact portion protruding from a substantially central portion, a second contact piece portion extending from one side surface, and a first connection piece portion formed by standing upright in a direction orthogonal to the second connection piece portion And a terminal portion extending from one end, the sleeve terminal is inserted from the upper surface of the jack housing, the sleeve terminal is press-fitted from the inlet of the plug insertion hole, and the sleeve metal is The peripheral surface and the bottom surface and the side surface of the plug insertion hole are crimped and clamped to the first connecting piece portion and the second connecting piece portion, respectively.

(Operation) By thus providing the connecting piece on the sleeve terminal and sandwiching the connecting piece with the sleeve metal and the jack housing, the sleeve terminal can be fixed to the jack housing without caulking. Further, the sleeve terminal can be fixed in the jack housing by press fitting.

(Embodiment) Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 10. As shown in the drawing, in the jack of this embodiment, the sleeve terminal 4 is inserted into the jack insertion hole 2 of the jack housing 1 at the inlet side in a direction orthogonal to the direction of the hole 2. This sleeve terminal 4
A plug contact portion 4a formed by punching out a plate member having a substantially square shape by a press and protruding in a hemispherical shape at a central position thereof, and a second connection piece portion 4c extending from a side surface end. And the first contact piece portion 4 formed by erecting the bottom end of the plug contact portion 4a at a position perpendicular to the second connection piece portion 4c to the hemispherical side of the plug contact portion 4a.
b and a terminal portion 4d formed by extending from the bottom end, the second connection piece portion 4c is formed in the vicinity of the plug contact portion 4a, and the first connection piece portion 4b is formed. The second connecting piece portion 4c and the terminal portion 4d are erected so as to form a substantially right angle, and the overall shape is a V shape when viewed from the side.

The plug contact portion 4a, the first connecting piece portion 4b, and the second
The connecting piece 4c and the connecting piece 4c are arranged so as to face the plug insertion hole 2. The sleeve metal 3 is press-fitted and fixed to the inlet of the plug insertion hole 2a on the plug insertion side. The sleeve metal 3 includes a tubular portion 3a and a flange 3b.
And a tapered ring projection 3c is provided on the outer circumference of the distal end side of the cylindrical portion 3a in order to ensure press-fitting and fixing. By press-fitting this sleeve metal 3,
The first connecting piece portion 4b and the second connecting piece portion 4c of the sleeve terminal 4 are sandwiched between the outer circumference of the tip of the tubular portion 3a of the sleeve metal 3 and the jack housing 1, and the sleeve terminal 4 is prevented from coming off from the jack housing 1. It is fixed. In the jack housing 1, the contact terminals 5 and 6 are assembled with the spring contact portions 5a and 6a facing the plug insertion hole 2, and between the small step portions 1a and 1b formed on the upper surfaces of both sides of the jack housing 1, A cover 8 shown by a chain double-dashed line in FIG. 2 is attached to prevent the contact terminals 5 and 6 from coming off.

Next, an example of a method for assembling the jack according to the above embodiment of the present invention will be described.

First, the sleeve terminal 4 and the contact terminals 5 and 6 are inserted into the predetermined holes of the jack housing 1 from above. At this time, the sleeve terminal 4 is positioned by inserting the terminal portion 4d downward and projecting it downward of the jack housing 1 and at the same time bringing the lower surface of the first connecting piece portion 4b into contact with the bottom surface of the jack housing 1. It

After that, the sleeve metal 3 is press-fitted into the hole portion 2a and fixed to the jack housing 1 by the ring protrusion 3c, and the first portion is formed between the outer surface of the sleeve metal 3 on the inner side of the cylindrical portion 3a and the bottom surface of the hole portion 2a. The connecting terminal portion 4b of the above is sandwiched in the line contact state, and the second connecting piece portion 4c is similarly sandwiched in the line contact state between the side surface of the hole portion 2a, so that the sleeve terminal 4 is attached to the jack housing 1. Fix it. Further, the contact terminals 5 and 6 communicate with the plug insertion hole 2 and are inserted into the terminal insertion groove having substantially the same shape as the contact terminal. Then, the lid 8 is attached at a predetermined position, and the assembly of the jack is completed.

In such a jack, when the plug 7 is inserted as shown in FIG. 1, the sleeve 7a of the plug 7 is brought into contact with the plug contact portion 4a, and the ring 7b is brought into contact with the spring contact portion 5a.
a is brought into contact, and the spring contact portion 6a is brought into contact with the chip 7c.

(Effect of the Invention) As described above, the jack according to the present invention has the second connecting piece extending from one side to the sleeve terminal having the substantially flat plate-like shape and having the plug contact portion protruding to the central position. Part, a first connection piece part formed by standing upright in a direction orthogonal to the second connection piece part, and a terminal part extending from one end, and a sleeve terminal is inserted and attached from the upper surface of the jack housing. , The outer peripheral surface of the sleeve metal and the bottom surface and the side surface of the plug insertion hole are crimped and clamped to the first connecting piece portion and the second connecting piece portion, respectively. And the side surface and bottom surface of the housing to prevent the plug from coming into contact with the plug contact portion, such as rotation and other movements, and caulking. This has an extremely excellent effect that the number of vertical processes can be reduced.
