Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved relay shack in which the number of poles of the jack portion is three.

A three-prong relay jack has two terminals on one side of the shack part of the inner cavity of the three-prong connector, which contact the inner pole (first pole) and second pole of the plug inserted there. Arrange the connection terminals and connect the fttll G on the other shirt.
Arrange two connecting terminals that contact the inner pole and second pole of the plug inserted therein, and set these connecting terminals in a state in which the corresponding connecting terminal and the connecting terminal are in contact with each other. A pair of plugs is held in the inner cavity of the potty, but at that time, the plugs must be firmly pressed against the inner and second poles of the plug inserted into the shirt/7s, and at the same time, they must not interfere with each other. It is required to assemble the product in such a way that it will not cause damage.

For this reason, the three-pole relay jack has a problem in that the assembly means for assembling the connection terminal into the inner cavity of its body is complicated, making assembly as a relay jack troublesome.

The present invention has been made to solve this problem, and while making it easy to assemble the connecting terminal into the body cavity, the silk-attached connecting terminal
The plug G inserted into the shank part must be firmly pressed against the plug G to maintain connection continuity, and the operation at that time can be performed without interfering with each other. target

Therefore, the present invention has been made based on the knowledge obtained as a result of various studies to achieve the above-mentioned object.

In other words, the connection terminal built into the body of the relay jack has
Two connection terminals are punched out of a springy metal plate and formed into a horizontally oriented substantially identical G-shape each having a pair of contact pieces facing each other so as to form a forked shape on the front end side and the rear end side, and Part 2
Two connecting terminals having substantially the same shape can be used by making the legs of the fork-shaped contact piece of one connection terminal long (and shortening the legs of the fork-shaped contact piece of the other connection terminal). If you combine connection terminals of approximately the same shape as shown in the axial direction of the body of the relay shack so that they cross each other and install them inside the body, the front and rear of each plug G to be inserted into the rear jack section G will be connected. It has been found that the pair of contact pieces forming the fork shape come into strong contact with each other and conduction is established, and the structure of the connection terminal is significantly simplified and functions reliably. Moreover, it is difficult to assemble two connecting terminals formed in the same shape in this way into the body in a crossed state when viewed from the axial direction of the body.
The two connection terminals, which have approximately the same shape, are assembled and held in a splittable holding cylinder made of synthetic resin, and the holding cylinder is fitted into a metal outer cylinder that forms the body. For example, this is due to the fact that it has been found that it can be easily incorporated into the body.

Therefore, in the present invention, two connection terminals are formed by punching out a resilient metal plate and are formed into substantially the same shape, each having a pair of fork-shaped contact pieces on both front and rear ends. A holding method in which the legs of a fork-shaped contact piece of a connecting terminal are long and the legs of a fork-shaped contact piece of the other connecting terminal are formed short, and these two connecting terminals are formed into a cylindrical shape that can be separated from a synthetic resin material. Inside the cylinder,
The assembly is maintained in a state in which the holding cylinders are assembled so that they are crossed from the axial direction, and the holding cylinder is fitted into a metal outer cylinder that becomes the body, and the front and rear ends of the outer cylinder are The present invention proposes a means for constructing a three-pole relay jack by fitting socket fittings.

Next, embodiments of the present invention will be described in detail with reference to the drawings.

The fork-shaped contact piece (21a) (2) (a) and the fork-shaped contact piece (22a)
One of the engaging grooves (24a) provided on the outer edge of the connecting portion (23a) that connects the connecting terminal (22a) with the connecting portion (24a) of the other connecting terminal (2b)
A notch groove (2ηG) wider than the front and rear width of the holding cylinder (23b) is formed to hold the two connecting terminals (2a) and (2b).
When the terminals 1 and 1 are assembled in a crossed state when viewed from the axial direction, the notched groove (27) is configured to straddle the connecting portion (23b) of the other connecting terminal (2b).

These two connecting terminals (2a) and (2b) forming a roughly H shape
The holding cylinder (1), which is assembled and held in a crossed state, is inserted into the inner cavity of the metal outer cylinder (3) that becomes the body of the relay jack B, as shown in Fig. 1. The cylindrical body G to be fitted is molded from a synthetic resin material, and at that time, it is molded into a shape divided into two halves, as shown at A and G in FIG. And they are divided and held fd
The inside of (la) has the connection terminals (2a) and (2b).
) long and short guide grooves (12a) into which the left and right side edges of (
12b), as shown in Fig. 2, tftJ
The guide grooves (12a) are formed with a phase difference of 90 degrees with both ends of the image portion (12a) being closed.
- At the longitudinal center of (12b), there is a connection terminal (2
Engagement grooves (24a) and (24a) formed on each side edge of a) and (2b)
The protrusions 0'') and (marks) that fit into (2jb) are formed respectively.In addition, the long guide grooves (12a) and (12a) are formed by butting the two divided retainers @ (1a) together. Each split holding cylinder (1a) is formed into two halves on the split abutment surface when assembled into the holding cylinder (1).

Therefore, in order to assemble the connection terminals (2a) and (2b) into the holding tube (1), first, insert the contact pieces (21b) and ( 21b)
, Connect the connecting terminal (2b) on the side where the legs of (22b) and (22b) are shortened so that its engagement groove (24b) is connected to the protrusion (11).
), and next, hold the connecting terminal (2a) on the side with the longer leg of the contact piece in a horizontal state, and insert the connecting terminal (2b) into the notch groove (with two forces). Straddle the vertical connection part (23b) and connect the retaining groove (
24a) engages with the projection circle, and the long guide groove (
12a), and then the other divided holding cylinder (1a
) and assemble the integral holding cylinder (1).

The holding cylinder (1) holding the two connection terminals (2a) and (2b) is then attached to the metal outer cylinder (5) that will become the body, as shown in Fig. 1. By fitting the inside G of 3) and fitting socket fittings (4) and (4) made of metal to both the front and rear ends of the outside @(3), the two-pole relay jack B can be connected. Can be assembled.

The three-prong relay jack B assembled in this way has two roughly H-shaped connection terminals (2a) and (2b) inserted inside.
When viewed from the axial direction, as shown in E and G in Fig. 1, G is in a crossed state, and as shown by the chain lines at A and G in Fig. 1, the front and rear When the plugs b are inserted into the respective jacks, the fork-shaped contact piece (2) of the connection terminal (2b) on the side with the shorter leg of the contact piece
