The present invention relates to a DIN connector, and more particularly to an improved DIN connector that provides a good turn for extraneous interference and is easy to assemble.

The same conventional DIN connector as shown in FIG. 4 is actually formed of a metal hull (b) and a body (a). The main body is provided with two ground terminals (c), a notch (d) is provided below the terminal (c), and projections formed on each of the inner sides of the line (b) into the terminal (c) can be bound. The projections formed on each of the inner side of the hull (b) can be bound on the a) so that the projections formed on each of the inner sides of the hull (b) on the body (a) can be bound so that the hull (b) moves back and forth on the body (a). Prevent it. The hull (b) has a recess (f) for accommodating the terminal (c) but has an inverted U-shape at a position corresponding to the terminal (c). After the hull (b) is mounted on the body, the two terminals (c) are leaded in the recess (f) to ensure the hull (b) and their mechanical and electrical connections, so that the hull (b) functions as a ground. Because of this, the connector can be shielded from interference of foreign signals.

However, the conventional DIN connector described above has several disadvantages.

First, metal hulls provide shielding only for the three sides x, y and z, while the back side provided with recess f is still affected by external electromagnetic waves.

Secondly, the task of assembling the two parts (a) and (b) together is relatively complicated because it requires a soldering step.

It is therefore an object of the present invention to provide an improved DIN connector that overcomes the above disadvantages.

According to the present invention, the first end point is eliminated by providing additional shielding on the back side of the hull, which is open in a different way than conventional DIN connectors and which is not provided with a shield.

According to another feature of the present invention, the second end point is eliminated by providing a specially designed terminal and hull which secures the connection (mechanical and electrical) between the body and the hull without the need for soldering.

According to the present invention, each terminal has a notch at the free end to make the elastic compression degree of the free end constant so that the terminal can be easily inserted into the hole corresponding to the hull. The structure of the terminal is that once it is entered into the hole, the terminal can no longer be pulled out, and the terminal is firmly connected on the edge of the hole to ensure electrical and mechanical connection between the hull and the main body. This eliminates the need for soldering.

According to another feature of the present invention, the electrical connection between the body and the hull is reliably ensured by two tongues on the hull side which elastically contact the terminals.

The present invention will be described in more detail with reference to the drawings.

Referring to FIG. 1, the DIN connector of the present invention also includes a main body a1 and a metal hull b1. Like the conventional DIN connector, the body a1 also has two notches d (only one shown) and two ground terminals c1 for the projection e of the hull b1. However, unlike the conventional DIN connector, the hull b1 is not open at the rear side. That is, the hull b1 provides shielding on the rear side W1 in addition to the small axes X1, Y1 and Z1, and eliminates interference from the rear side.

The back side W1 is provided with two holes 1 into which the tip 21 of each terminal is inserted.

The tip 21 is arrow-shaped and carries a shank 22 as shown in FIG.

The shank 22 extends at a constant distance along the axial direction of the terminal c1.

Referring to FIG. 2, the top width of the shank 22 is slightly larger than the size of the hole 1.

However, once the terminal c1 enters the hole 1, the shank 22 is slightly compressed toward the space 23 and fixed. In this way, the shank 22 is firmly connected to the edge of the hole 1 by the restoring force.

In order to ensure electrical connection between the body a1 and the hull b1, the hull is punched out of the hull and two tongues 3 elastically connected to the terminal c1 when the terminal c1 enters the hole 1; It is provided.

3 shows another embodiment of the present invention.

As in the first embodiment of FIG. 1, the DIN connector also has a body a2 and a hull b2 having an inner side X2, Y2, Z2 and W2. The hull b2 also has two tongues 3 to ensure electrical connection with the two terminals c of the body a2 (only one is shown).

Terminal c here is the same as the conventional DIN connector in FIG.

The hull b2 is not equipped with a terminal hole. However, soldering of the terminal c is unnecessary because the elastic connection of the tongue 3 is ensured. The hull b2 also has an additional two tongues e1 which can each be tethered in the two recesses 4 (only one shown) to provide a mechanical connection between the body a2 and the hull b2. It is guaranteed.

Part names (a1) to (z1) of the present invention shown in FIGS. 1 and 2 of the present invention and part names (a2) to (Z2) in a modification of the present invention as shown in FIG. Since only the Arabic numerals 1 and 2 are added differently to the alphabets for convenience of mutual equality or explanation, the claims are intended to claim the rights with the emphasis on the first and second degrees.

Claims (3)

In a DIN connector consisting of a substantially cuboid body having two elongated ground terminals, and a metal hull that is constrained to the body and electrically connected to the ground terminal when bound to the body, shielding the body and three sides, The hull (b1) has a back side (w1) which is an additional side which shields the fourth side of the main body (a1) corresponding to the ground terminal (c1). 2. The hull (b1) is also provided with two tongues (3) which are elastically applied to the ground terminal (c1) when the body (a1) and the hull (b1) are constrained. DIN connector. According to claim 1, wherein the back side (w1) is provided with two holes (1), each of the ground terminal (c1) has an arrow-shaped tip 21 at a predetermined distance along the axial direction, It has a shank 22 having a width smaller than the diameter of each of the holes (1), the leading edge 21 is extended so as to penetrate the hole (1), respectively, the shank 22 is the main body (a1) And a force elastically applied to the edge of the hole (1) when the hull (b1) is constrained.
