Description

[Detailed description of the invention]

[0001]

The present invention relates to a U-shaped connector having a large number of U-slit terminals arranged in high density inside a terminal block made of an insulating material.
It relates to improvement of a slit terminal plate.

2. Description of the Related Art A U-slit type terminal plate in which a large number of U-slit terminals are juxtaposed at high density inside a terminal block made of an insulating material is known. In No. 5, no shield piece for eliminating interference between adjacent circuits is provided on the terminal block. In addition, conventional U
The slit terminal plate has a structure in which a ground wire is connected to a normal U slit terminal adjacent to each constituent circuit and grounded. In addition, in a relatively large terminal plate device other than the U slit terminal plate in which the U slit terminals are juxtaposed at a high density, a shield piece for eliminating interference between adjacent circuits has been provided so far. Each shield piece is electrically independent of each other, and therefore, it is necessary to connect a ground wire to each shield piece and ground it.

[0003]

As described above, the conventional high-density U-slit terminal plate does not include a shield piece for eliminating interference between adjacent circuits. As a result, problems such as generation of noise may occur. Further, in the conventional U-slit terminal board, the ground wire is connected to the adjacent normal U-slit terminal, so that there is a problem that the number of effective circuits in the terminal board is reduced. In view of the above, the present invention provides a vertical and horizontal shield piece for defining a large number of U-slit terminals for each block inside the terminal block, thereby eliminating interference between adjacent circuits. It is another object of the present invention to provide a U-slit terminal plate in which shield pieces are electrically connected so that a ground wire can be connected collectively.

[0004]

In order to achieve the above object, the present invention will be described in detail. According to the present invention, a large number of U-slit terminals are provided inside a terminal block made of insulating material. In the U-slit type terminal board arranged side by side, a long shield piece is attached substantially at the center of the terminal block in the longitudinal direction so as to define a U-slit terminal in the left-right direction. A U-slit terminal plate comprising a shield piece characterized by being provided with a short shield piece surrounding the U-slit terminal so as to be orthogonal to
In the invention according to claim 2, all of the long shield piece and the short shield piece are electrically connected, and a notch for press-fitting the ground wire is formed at an appropriate position of the long shield piece. 2 is a U-slit terminal plate.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the specific structure of the U-slit terminal plate of the present invention will be described in detail based on the illustrated embodiment. FIG. 1 is an exploded perspective view of the terminal block, the U-slit terminal and the shield piece of the present invention, and FIG. 2 is a perspective view of the U-slit terminal plate of FIG. FIG. Although the number of U-slit terminals is reduced in the illustrated U-slit terminal plate for convenience of description, actually, a larger number of U-slit terminals are arranged in parallel on the terminal block.

In FIG. 1, reference numeral 1 denotes a terminal block made of an insulating material.
The terminal block 1 is provided with a large number of concave grooves 2 for inserting covered wires. Reference numeral 3 denotes a U-slit terminal provided side by side inside the terminal block 1, and the connection conducting portions 4 and 4 at the tip of the U-slit terminal 3 are located in the concave groove 2 of the terminal block 1. I have. Therefore, when the covering wire constituting the circuit is inserted into the concave groove 2 of the terminal block 1 and press-fitted into the connection conducting portions 4 and 4 provided in the U-slit terminal 3, the covering is peeled off by the opposing connection pieces. Thus, a conduction state can be obtained.

Reference numeral 5 denotes a long shield piece provided substantially at the center of the terminal block 1 in the longitudinal direction. The long shield piece 5 is provided inside the terminal block 1 so that the U-slit terminal 3 is provided. The two connection conducting parts 4 and 4 are defined in the left-right direction. Notches 6 and 6 for connecting an earth wire are formed near both ends of the long shield piece 5, and an earth wire is formed in the notches 6 and 6 on the upper surface side of the terminal block 1. Grooves 7, 7 for insertion are formed.

Reference numeral 8 denotes a short shield piece disposed inside the terminal block 1 so as to be orthogonal to the long shield piece 5. A notch 9 is formed to be electrically connected. In the illustrated embodiment, grooves 10 are formed on the lower surface of the long shield piece 5 for inserting the cutouts 9 of the short shield piece 8. The short shield pieces 8 may be provided at every second U-slit terminal 3 as shown in the figure, or may be provided at every other U-slit terminal (not shown).

According to the U-slit terminal plate of the present invention, the U-slit terminals 3, 3... Disposed in the terminal block 1 are defined by the long shield pieces 5 and the short shield pieces 8, 8,. In this state, electrical interference between adjacent circuits can be prevented. Near the ends of the long shield piece 5, cuts 6 and 6 for press-fitting the ground wire are provided.
Is formed, so that it is not necessary to use an adjacent normal U-slit terminal for ground line connection as in the related art.

[0010]

According to the present invention, therefore, it is possible to provide a U-slit terminal plate in which a large number of U-slit terminals, in which interference between adjacent circuits is eliminated, are arranged in high density, and each shield piece is provided. Are electrically connected, so that the ground lines can be connected together, and the conventional disadvantage that the number of effective circuit components is reduced in relation to the ground lines can be eliminated.
