BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-core L-shaped coaxial connector, and more particularly to a multi-core L-shaped coaxial connector mounted on a printed circuit board or the like.

[0002]

2. Description of the Related Art A multi-core coaxial connector generally employs a structure in which, for example, a plurality of contacts, in which an outer conductor is fixed concentrically via an insulating material or the like, outside a center conductor, are arranged in parallel.

Conventionally, a multi-core coaxial connector of this type has
When a type coaxial connector is formed, contacts having straight shapes such as a center conductor and an outer conductor are bent at right angles to form L-shaped contacts, and the other ends of these L-shaped contacts are used as connecting portions. For example, a method has been adopted in which a hole or the like formed in a printed board is attached and connected to a corresponding conductive pattern on the printed board. In this case, the arrangement (location) of the terminals of the plurality of contacts of these connection parts with respect to the pattern of the printed board is generally performed using a locator.

[0004]

However, the conventional multi-core L-shaped coaxial connector has a structure in which a plurality of contacts are bent to form an L-shape as described above. Variations in the bending angle of the inner conductor and the outer conductor were inevitable, and thus the arrangement of the terminals on the printed circuit board and the like was poor, and there was a problem in the mountability to the circuit board.

Therefore, a technical problem of the present invention is to provide a multi-core L-type coaxial connector which does not have the above-mentioned problems and has a good arrangement of terminals at a connection portion with respect to a printed circuit board.

A multi-core arrangement arranged along a second axis intersecting the core, wherein exposed ends of the first and second center conductors and the first and second outer conductors are connected to each other; An L-shaped coaxial connector is obtained. According to the present invention, in the multi-core L-shaped coaxial connector, the exposed second center conductor and the second outer conductor receive the exposed first center conductor and the first outer conductor. Are formed, and a multi-core L-shaped coaxial connector is obtained. According to the present invention, in the multi-core L-shaped coaxial connector, an insulating material is provided between the first center conductor and the first outer conductor, and a tip of the exposed first center conductor is A multi-core L-shaped coaxial connector is obtained, wherein the multi-core L-shaped coaxial connector is in contact with the insulating material, and a tip of the first outer conductor is in contact with the first housing.

[0007]

According to the present invention, a multi-core L-shaped coaxial connector is formed by a second member connected to a substrate and a first member connected to the second member without performing conventional bending. Can be. That is, after connecting the connection portion of the second member to the printed circuit board, the first center conductor of the first member and the first center conductor of the first member are connected to the exposed ends of the second center conductor and the second outer conductor of the second member. A multi-core L-shaped coaxial connector can be formed by connecting the exposed ends of the second external conductor. Therefore, in the second member, the arrangement of the terminals in the contacts can be made orderly and uniform, and the arrangement of the terminals with respect to the printed circuit board is stable and the mounting is good.
