Abstract

PROBLEM TO BE SOLVED: To facilitate the relay between a device inner part and an external cable, improve the safety, and reduce the cost by mounting a fixing base made of an insulating material on the extension tip connector of an extension cable with connector. SOLUTION: An extension tip connector 3 is mounted on the front surface side of a rectangular insulating substrate 1 by soldering or screwing, or a connector integrally molded with the base is formed. An extension tip connector 5 having the structure reverse to the connector 3 is prepared, and the pins of the same number are straightly connected to each other to form an extension cable 4. The connection is performed by soldering or pressure connection. To fix the base to the device surface, in case of simple type, fixing holes 2 are bored in four angles of the substrate 1, threaded holes are bored on the device surface subjected to mounting, and bolts are inserted from the surface side followed by screwing, or nuts are prepared on the reverse side of the base followed by screwing. Thus, the relay of the device inner part to an external cable is facilitated, the safety is improved, and the cost is reduced.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector relay system for relaying on the surface of a device when an internal device and an external device of the device are connected by communication such as RS232C.

[0002]

2. Description of the Related Art Recent manufacturing-related equipment is compact, compliant with waterproof standards, compatible with clean rooms, etc., because the control equipment is installed deep inside the equipment, and the equipment has a closed structure. It is very difficult to make changes with a PC or a dedicated tool. Semiconductor manufacturing equipment is particularly strict, and it is not allowed to open the equipment at the manufacturing site. In order to cope with such a situation, a relay structure for connecting the internal equipment of the apparatus and the external equipment without opening the apparatus has been required. However, there are the following problems in realizing these. Conventionally, for cable extension and relay, commercially available products include extension cables with plug connectors and socket connectors on both ends, and adapter connectors with two connectors attached back to back. I can't fix it. Therefore, equipment manufacturers make connector mounting holes and wiring holes on the surface of the equipment, fix the connector directly on the surface, and wire the extension source connector cable by soldering etc. to the fixed extension destination connector to realize a relay structure. Was. However, in this case, the wiring work on the surface of the device is troublesome each time. In general, the connector is larger than the wiring hole, so it is not possible to make the cable first and then pass the connector through the wiring hole. Since the connector fixing part is directly attached to the metal surface, noise on the metal surface will be transferred to the connector ground,
It adversely affects the communication signal. In addition, since it is difficult to get a sealed structure, a waterproof structure cannot be used. If multiple cable relays on the device surface are required, drill the required number of mounting holes,
Wiring work is required.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention According to the present invention, (a) the cable relay connector cannot be fixed to the surface of the device. (B) When the number of relay connectors increases, the installation work also increases. (C) Noise is recorded on the connector. (D) Connector wiring work on the device surface is troublesome. (E) If the connector is relayed, the waterproof structure cannot be achieved. It is to solve the above.

[0004]

[Means for Solving the Problems]

(B) Attach the connector to the front side of the rectangular insulating board by soldering or screwing. Or make a connector integrally molded with an insulating substrate. (B) Prepare an extension connector that has a structure opposite to that of the extension connector attached to this insulating board, and straight connect the same pin numbers to make an extension cable. The connection method is soldering or pressure welding. In this case, the opposite structure of the connector means, in the case of the plug connector, the opposite structure means a socket connector. In addition, at the time of (a), mount the connector on the back side of the insulating board, connect the front side connector on the board in the same way as above, and connect the extension cable of the straight connection with the connector at both ends there. You may use the connection method. In this case, the connector of the extension source and the connector of the extension destination are finally made to have opposite structures. (C) As a method of fixing to the device surface, in the case of the simple type, make holes in the four corners of the insulating substrate, make a threaded hole on the device surface to be attached, insert a bolt from the surface side,
Secure with screws. Alternatively, prepare a nut on the back side of the plate and fix it with a screw. (D) For the waterproof type, attach the extension connector to the insulating board, and attach the fixing screws for the fixing brackets to the top, bottom, left and right of the connector. Also, the extension cables are connected in the same manner as in (b) above. (E) In the case of the waterproof type, an extension connector,
Install the rubber packing around the four fixing screws. (F) Attach a waterproof cover to the front. (G) The cover has a space that does not contact the extension connector and has a frame that can be sealed with rubber-like packing. (G) The cover should be attached so that it can be opened and closed easily and there is no displacement of the seal, and the hinge is connected at the bottom and the upper part can be screwed and fixed by hand. (H) On the back surface of the substrate, a prism or a cylindrical frame is attached so as to surround the screw and the wiring. This is the size of the mounting holes drilled in the surface of the device. (I) Attach a rubber packing that surrounds the frame and fits between the insulating substrate and the device surface. . (G) Attach a cross-shaped hard plate-like fixing bracket with a push claw that is about the height of the frame on the back. (L) A threaded hole is opened in the four-direction longitudinal portion of the fixing bracket, and the fixing screws provided on the top, bottom, left, and right of the extension destination connector are turned from the front side, and the insulating board sandwiches the rubber-like packing. , Can be closely attached to the device surface. (O) The waterproof cable repeater attached can be completely waterproofed by closing the waterproof cover. (W) Further, in the case of this surface mounting structure, by loosening all four fixing screws from the beginning, inserting them obliquely into the mounting holes and tightening the fixing screws, the device surface can be easily attached from the front.

[0005]

EXAMPLES In carrying out the present invention, the following can be performed. (B) The relay connector of the cable can be easily fixed to the device surface. (B) Even if the number of relay connectors is increased, it can be fixed by an easy method for one. (C) Since it is mounted on an insulating material, it is difficult for noise to be placed on the connector. (D) Wiring work is not required on the device surface. (E) The connector repeater can be installed even where waterproofness is required. However, it is not waterproof when connected to equipment. (F) The connector repeater can be fixed from the front side.

[0006]

According to the present invention, a cable relay structure inside and outside the device, which has been very troublesome for a mechanical device maker, can be easily realized. By standardizing such a connector relay system, in terms of safety, the noise resistance of communication during cable relay is improved and the device is waterproof. In terms of cost reduction,
Benefits such as reduced equipment startup time and improved maintainability can be obtained.
