Description

BNC type connecting member for test of visual device}

The present invention relates to a BNC type connector for testing video equipment, and more particularly, a BNC type connector that connects between a supply and a receiver when transmitting a high frequency video signal to inspect a video equipment for failure in an automatic production equipment. It is about.

In the line of automatic production of video equipment such as DVD, VCR, set-top box, in order to test whether the video equipment is defective, the high-speed video signal is transmitted between the test equipment and the video equipment. These connectors require free up, down, left and right movements on the production line.

On the other hand, the high frequency video signal has a property of spreading in all directions, and when a video signal is made by contacting with a general pin, the transmission signal is unstable.

In order to stably supply the video signal, the main body of the supply unit and the receiver unit should be contacted between the supply unit and the receiver unit, and the terminals for transmitting the video signal inside the main unit should be contacted.

As a result, the video signal can be transmitted by preventing the spread of the video signal and preventing the interference of the external signal.

The BNC (Bayonet Neil-concelman connector) has been developed to stably transmit the high frequency video signal. As the BNC is a coaxial connector for transmitting a video signal, the video signal is separated and transmitted using a separate cable. The image quality is clear when there is little interference of the signal and the image is displayed on the screen.

7 is an exploded perspective view of a conventional BNC connector.

As shown, the BNC connector is fitted to the receiving connector 4 having two engaging projections 4b formed on the outer circumferential surface thereof, and the engaging projection 4b of the receiving connector 4 to be coupled by rotation of the rotating part 5a. Coupling guide groove (5c) is formed, to support the rotation of the rotating portion (5a), the coupling connector formed by being separated into a fixed portion (5b) formed with an introduction protrusion (5d) to be introduced into the receiving connector (4) 5) consists of.

In the above configuration, when the coupling connector 5 is fitted to the receiving connector 4, the coupling guide groove 5c of the coupling connector 5 is inserted into the coupling protrusion 4b of the accommodation connector 4, and then pushed. When rotating the rotating portion (5a) of the coupling connector (5) while the engaging guide groove (5c) moves along the coupling projection (4b), the incoming projection (5d) is fixed to the fixed portion (5b) receiving connector (4) The coupling connector 5 is completely coupled to the receiving connector 4 while being fitted to the coupling connector 5.

In order to separate the coupling connector 5 into the accommodation connector 4, the rotary part 5a of the coupling connector 5 may be rotated in the opposite direction to the above-described direction.

In order to facilitate the coupling and disconnection of the receiving connector and the coupling connector during the testing of the automatic production line of the imaging equipment at the BNC connector, the coupling protrusion 4b of the receiving connector 4 is processed and removed. use.

As described above, the BNC connector, in which the engaging projection 4b is removed, is used as a connector by connecting the supply block and the receiving block, which are not shown through the difficult process, but the receiving connector 4 and the coupling connector 5 are repeated. In the case of the coupling, the coupling portion is easily worn and the inlet protrusion 5d formed at the center portion of the coupling connector 5 is bent, so that mutual coupling is poor or the image signal is not transmitted normally.

In addition, the connector is used to move up and down and left and right bar, because the coupling connector (5) is coupled to the receiving connector (4), so that the connectors can be combined only when the block is in the correct position when moving, the block is always constant by the cylinder There was a problem that the connector is coupled exactly to move by the distance.

In addition, since the BNC is used as it is except for the engaging projection (4b) of the pre-made BNC products, it is cumbersome and difficult to replace because it must be fixed by bolting on the side after forcing the BNC into the block. .

The present invention has been made to solve the above-described problems, the outside of the first contact the inner terminal for transmitting the video signal by the contraction of the spring in contact with the state can be transmitted to the video signal stably and the connectors are not coupled It provides BNC type connector for video equipment test that can be easily replaced in case of failure of connector or block because video signal is transmitted by contact.

Insulation part 334 is inserted and fixed inside the auxiliary connector 330, and coupling terminals 335 are inserted through the insulating part 334 to be exposed to both sides.

One side of the coupling terminal 335 is fitted with one end of the buddy 351 of the floating contact pin 350 and the other side is connected to the BNC cable (not shown) of the video signal.

The insulator 340 has a cylindrical shape formed to penetrate the space 341 therein, and a locking protrusion 342 is formed at one end thereof, so that the insulator 340 is positioned in the space 321 formed inside the floating ground contact hole 320. The flag 342 is caught and no longer inserted into it.

The insulator 340 insulates the inner floating contact pin 350 and the outer floating ground contact hole 320 from each other.

The flow contact pin 350 is plunged by the plunger 353 by the spring 352 inserted into the buddy 351 (body), so that the plunger 353 flows.

The floating contact pin 350 penetrates through the space 341 of the insulator 340 so that one end of the buddy 351 is fitted into the coupling terminal 335 of the auxiliary connector 330.

Spring 360 is located in the receiving hole 313 of the housing 310, one side is coupled to the end of the auxiliary connector 330 screwed to the receiving hole 313, the other side is the floating ground contact hole 320 It is supported by the locking projection 322 of the flow ground contact hole 320 is to retreat forward.

As shown in FIG. 4, the one end of the floating contact pin 350 is configured to pass through the space 341 in the insulator 340 to be screwed into the housing 310. It is fitted to the coupling terminal 335.

The insulator 340 is coupled so that the locking protrusion 342 is caught by the floating ground contact hole 320 so as to be fitted into the receiving hole 313 of the housing 310 together with the floating ground contact hole 320.

At this time, the locking protrusion 322 of the floating ground contact hole 320 is caught by the locking protrusion 315 formed so that the radius of the receiving hole 313 is smaller, the floating ground contact hole 320 is not separated out.

In addition, a portion of the floating ground contact hole 320 and the plunger 353 of the floating contact pin 350 located in the space 321 of the floating ground contact hole 320 protrude out of the housing 310, where the floating contact The protruding length of the pin 350 is smaller than the protruding length of the floating ground contact hole 320 so that the end of the floating contact pin 350 is located inside the floating ground contact hole 320.

One side of the fixed contact terminal 410 is in contact with the plunger 353 of the floating contact pin 350, the other side is connected to the BNC cable (not shown) of the video signal.

6A and 6B are cross-sectional views in a state in which a connector is connected by the present invention.

In FIG. 2, when the connectors 300 and 400 approach the blocks 100 and 200 screwed to each other to test the imaging device, in FIG. 6A, first, the flow ground of the main body 420 of the receiver connector 400 and the supply connector 300 is shown. The contact hole 320 is contacted and grounded.

In FIG. 6B, when the blocks 100 and 200 are closer to each other, the spring 360 of the supply connector 300 contracts and the retracted state in which the floating ground contact hole 320 is in contact with the main body 420 of the receiver connector 400. As the plunger 353 of the floating contact pin 350 protrudes and contacts the fixed contact terminal 410 of the receiver connector 400, the image signal is transmitted while the outside is grounded.

After the test is finished, if the blocks 100 and 200 are separated from each other, the floating contact pin 350 of the supply connector 300 and the fixed contact terminal 410 of the receiver connector 400 fall, and then the supply connector 300 The floating ground contact hole 320 and the main body 420 of the receiver connector 400 fall.

At this time, while the contracted spring 360 is restored, the floating ground contact hole 320 returns to its original position.

In this way, the image signal is transmitted from the inside while the outside is grounded, so that the image signal can be stably transmitted.

On the other hand, if the connector is broken and cannot be used, the broken connector 300, 400 is rotated by hand to separate it from the blocks 100 and 200, and the new connector 300 and 400 is screwed into the coupling holes 140 and 230 of the block 100 and 200. Easy to replace by combining.

This is true even when the blocks 100 and 200 fail.

In addition, when the coupling holes 140 and 230 are formed in two blocks in the blocks 100 and 200 and one of the coupling holes formed in the upper and lower sides cannot be used, the opposite coupling hole may be used.

As discussed above, the present invention provides the following effects.

First, it is convenient because it does not go through the process of removing the coupling protrusion of the pre-fabricated BNC, and even if the contact part of the supply connector and the receiver part are repeatedly contacted, they are not worn because the connectors are not connected to each other. The video signal can be stably transmitted by allowing the inner terminals of the video signal to be contacted by contraction of the inner side.

Second, since the video signal is transmitted by the contact between the connectors, when the connector is moved and used, the video signal can be transmitted by the contact even when the connector is not in the correct position but in close proximity, and the floating ground contact is moved forward by the spring. Since the retracting flow distance is secured, it is possible to make contact with the fixed contact terminal of the receiver connector even if the block does not always move by a certain distance by the cylinder.

Third, since the connectors are coupled to each other by screwing the blocks, it is easy to replace them in the event of a failure in the connectors or blocks.
