Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention is a BN that connects a concentric cable to a pair of parallel terminals.
It is related to C receptacle test adapter and is used for connecting oscilloscope, measuring instrument, signal generator, etc.

[Conventional technology]

A conventional test adapter with a BNC receptacle has a pair of banana plugs fixed to its front end.

[Problems to be solved by the invention]

Therefore, its use was limited to connection to a banana socket, and the entire test cable had to be replaced according to the experimental process, which was uneconomical.

The present invention is applicable to such BNC receptacle test adapters other than banana sockets.

[Means for solving problems]

In the present invention, a BNC receptacle 2 for connecting a BNC connector (concentric connector for a concentric cable) is provided rearward in the center of the upper surface of a body 1 made of an insulator, and a tube 6 made of a pair of conductors is provided on both sides of the body 1. 6 is buried in the front-rear direction, the tubes 6 and 6 are electrically connected to the BNC receptacle 2, and the rear end opening 6a is a fitting hole for the banana plug 7 connected to one end of the test cable. In the adapter, the front ends of the cylinders 6 and 6 are opened, and female threads 6b and 6b are provided on the inner surface of the front end openings of the cylinders, while the banana plug 8, the spade plug 9 and the worm clip 10 have this screw.
Male screws 8a, 9a, 10a to be screwed with 6b are provided respectively, and through holes 11, 11 for fitting another banana plug 7 orthogonal to the above-mentioned tubes 6, 6 are provided on both sides of the front part of the main body 1. BNC receptacle test adapter.

[Action]

The female screws 6a, 6a can be freely combined and used by screwing any one of the banana plug 8, the spade plug 9, the worm clip 10, etc.

〔Example〕

A BNC receptacle 2 for connecting a BNC connector (concentric connector for concentric cables) is provided rearward at the center of the upper surface of a main body 1 made of an insulator. 3 is an outer cylinder made of the conductor,
As shown in FIG. 3, a central tube 5 of a conductor for connecting a core wire via an insulator 4 is provided in the center of the inside.

Cylinders 6, 6 made of a pair of conductors are embedded in the front and rear direction on both sides of the main body 1, and the cylinders 6, 6 are electrically connected to the BNC receptacle 2, respectively. Both ends before and after this cylinder 6, 6 are open,
The rear end opening 6a is a fitting hole for the banana plug 7 connected to one end of the test cable. Female elements 6b, 6b are provided on the inner surface of the front end openings of the cylinders 6, 6, while a banana plug 8, a spade plug 9, and a worm clip 10 have a male screw 8a screwed to the screw 6b, as shown in FIG. Provide 9a and 10a respectively.

Through holes 11, 11 orthogonal to the cylinders 6, 6 are provided on both sides of the front part of the main body 1, and the through holes 11, 11 are used as fitting holes for the banana plug 7.

Next, the usage of this device will be described.

Connect the BNC connector of the test cable to the BNC receptacle 2 of the main body 1 or fit the banana plugs 7 and 7 of the test cable into the rear end openings 6a and 6a, while the female screw 6b at the front end
The test cable can be freely connected to any device by selecting one of the insect clip 10, spade plug 9 and banana plug 8 into 6b and screwing it in.
The banana plugs 7, 7 can also be vertically connected to the through holes 11, 11.

[Effect of device]

As described above, according to the present invention, the test cable can be freely combined with any device according to the test use of research and experiment, which is convenient and very economical.

Further, in the present invention, the banana plugs 7 without screws can be connected by the rear end openings 6a of the cylinders 6,6, and the banana plugs 7 orthogonal to the cylinders 6,6 can be fitted on both front sides of the main body 1. Since the through holes 11 and 11 are provided, the banana plug 7 can be connected in the direction orthogonal to the main body 1.
