Description

TECHNICAL FIELD

[0001] The present application relates to the field of coupler connectors, in particular to a coupler connector with good sealing performance. BACKGROUND

[0002] As the core physical interface component of electronic / optical communication systems, the performance parameters (such as insertion loss, return loss, impedance matching degree, etc.) of the coupler connector will directly determine the integrity, fidelity and anti-interference ability of the signal in the transmission process. The mechanical stability, contact reliability and environmental adaptability of the element will also affect the long-term operation performance of the entire communication system, such as maintaining stable signal transmission characteristics in high temperature, vibration or humid environment.

[0003] However, the existing coupler connector has the following problems during use:

[0004] Before connection, cleaning is required, at this time, air jet is used for cleaning, which is often not comprehensive before and during connection, and the cleaning effect is poor;

[0005] After connection, the inside of the connector is often connected, and when one side of the connector is not sealed tightly after sealing, the line slot cannot be sealed in time, which will affect the entire connector, and the line connector which is easily damaged by water and dust will be affected;

[0006] During connection, the connection is often sealed with a sealing gasket, but some connections are damaged or the contact surface is uneven after long-term use, and the sealing gasket is often difficult to seal completely, and timely sealing during connection causes poor sealing effect. SUMMARY

[0007] The purpose of the present application is to provide a coupler connector with good sealing performance, which provides a coupler connector with good sealing effect, comprehensive cleaning before connection and good line protection effect.

[0008] The present application is a coupler connector with good sealing performance, comprising a first connector and a second connector, the first connector and the second connector are provided with an air-filled sealing assembly on the side surface, the first connector and the second connector are provided with a line sealing assembly on the other side surface, and the first connector and the second connector are clamped and connected;

[0009] The air-filled sealing assembly comprises an air bag and a sealing gasket, the air bag is arranged on the outer contact surface of the first connector and the second connector, and the sealing gasket is arranged on one side of the air bag and located on the inner contact surface of the air bag and the first connector and the second connector;

[0010] The airbag and the sealing gasket are provided in twos, respectively located near the internal wiring, and one of each of the first connector and the second connector is provided.

[0011] During operation, as the two connectors move closer to each other during the connection process, the locking blocks of the first and second connectors press against the sliding blocks on one side of each other. Then, they move forward, and the sliding blocks press against the moving rod. The moving rod, in conjunction with the air cylinder, outputs gas. The other part of the gas enters the air bladder through the air supply pipe. When the connection is completed, the air bladder expands and compresses the sealing gasket. When the contact surface at the connection point is uneven, the sealing gasket is made to fit more tightly against the side wall of the connection point, preventing the sealing gasket from failing to fit the connection point and improving the tightness of the seal. Moreover, it can seal as the connection process progresses, slowly inflating during the connection process, making it more adaptable to the connection environment.

[0012] The circuit sealing assembly includes a fixing ring, a first telescopic rod, a spring, and a circuit tube. The fixing ring is connected to one side of the first connector. Several springs are respectively sleeved around several first telescopic rods and are disposed on one side of the fixing ring. The circuit tube is movably disposed inside the fixing ring and is connected to one side of the first telescopic rod.

[0013] The circuit tubes are provided with a number of circuit grooves, which are arranged in a circular array and cooperate with the fixing rings.

[0014] The wiring trough is located at the end of the wiring tube, and the wiring tube can move in the inner ring of the fixed ring. During the movement, part of the wiring trough will be hidden in the fixed ring, and the rest of the wiring can be gathered.

[0015] During operation, as the two connectors move closer to each other during the connection process, the locking blocks of the first and second connectors press against the moving parts on one side of each other, and then move forward, causing the moving parts to press against the tail end of the wire tube and move the wire tube. After the connection is completed, part of the wire groove on the wire tube will be hidden in the fixing ring, and the remaining wires will be tightened to fill the wire groove, so that the gaps in the wire groove can be hidden. The remaining wires fill the wire groove, and the wire groove is immediately and completely sealed after the connection is completed, thus sealing the wire groove in a timely manner.

[0016] The inflatable sealing assembly also includes a movable rod, an air cylinder, and an air supply pipe. The movable rod is movably disposed on one side of the first connector, and the air cylinder is fixedly disposed on one side of the first connector. The movable rod and the air cylinder cooperate with each other. One end of the air supply pipe is connected to the air cylinder, and the other end of the air supply pipe is connected to the air bag.

[0017] The moving rod, air cylinder, and air supply pipe are each provided in duplicate, and are respectively installed on the first connector and the second connector.

[0018] Both the first connector and the second connector have a connecting component on one side;

[0019] The connecting assembly includes a semi-rotating disk, a rotating shaft, a lever, a third telescopic rod, and a second return spring. The semi-rotating disk is movably disposed on one side of the first connector and the second connector via the rotating shaft. One end of the lever is connected to one side of the semi-rotating disk. One end of the third telescopic rod is movably disposed on one side of the first connector and the second connector. The other end of the third telescopic rod is connected to one side of the lever. The second return spring is sleeved around the third telescopic rod.

[0020] Among them, there are two of each of the semi-rotating disk, rotating shaft, lever, third telescopic rod and second return spring, which are respectively installed on the first connector and the second connector;

[0021] During operation, the first connector and the second connector can be combined into a connector head. The first connector and the second connector are symmetrically equipped with locking blocks and slots that fit with each other. The two connectors move closer to each other. When the two semi-rotating disks come into contact with each other, the semi-rotating disks start to rotate. The lever is driven to rotate, and the third telescopic rod and the second return spring are extended by the lever, dividing the connector head into two areas. This allows the circuit to be in two separate areas without affecting each other. Combined with the circuit sealing, this improves the protection of the circuit.

[0022] An adjustment and cleaning assembly is also provided on one side of the first connector and the second connector;

[0023] The adjustment and cleaning assembly includes a delivery pipe, a connecting belt, and a cleaner. One end of the delivery pipe is connected to an air cylinder, the connecting belt is located on one side of the semi-rotating disc, and the cleaner is located on one side of the connecting belt. One end of the delivery pipe is connected to the air cylinder, and the other end of the delivery pipe is connected to the cleaner.

[0024] The conveyor pipe, the connecting belt, and the cleaner are all provided in twos, with the two cleaners respectively mounted on the semi-rotating disc via the connecting belt;

[0025] During operation, as the two connectors move closer to each other, the locking blocks of the first and second connectors press against the sliding blocks on one side of each other. Then, they move forward, and the sliding blocks press against the moving rod. The moving rod, in conjunction with the air cylinder, outputs gas. A portion of the gas enters the cleaner through the delivery pipe. During connection, the semi-rotating disc rotates, causing the cleaner to rotate. Several air jets are installed on one side of the cleaner to thoroughly clean the first and second connectors before connection is completed. This allows for cleaning of the inside of the connectors during connection, and cleaning is completed just as the connection is finished, improving the timeliness of cleaning.

[0026] The inner sides of the first connector and the second connector are provided with a movable component. The movable component includes a second telescopic rod, a first return spring, a sliding block and a movable part. The inner sides of the first connector and the second connector are each provided with an inner groove. The second telescopic rod is fixedly disposed on one side of the inner groove. The first return spring is sleeved around the second telescopic rod. The sliding block is slidably engaged with the inner groove and connected to one side of the second telescopic rod. The movable part is connected to the top of the sliding block.

[0027] The second telescopic rod, the first reset spring, the sliding block, and the moving part are all provided in twos, which respectively cooperate with the two line sealing assemblies.

[0028] One side of the movable component engages with the wiring conduit, and the sliding block engages with the movable rod.

[0029] The first connector and the second connector are provided with a sliding groove on their tops. A connecting rod is provided in the sliding groove. One end of the connecting rod is connected to one side of the lever, and the other end of the connecting rod is provided with a handle. The connecting rod slides in conjunction with the sliding groove.

[0030] The slide groove is equipped with a sealing strip, and the side of the connector where the slide groove is located fits against other surfaces of the machine to enhance the seal.

[0031] During operation, by rotating the handles of the two levers, the first and second connectors can be moved in opposite directions to disassemble them. The enlarged wiring groove makes it easier to disassemble the connectors, and the wiring seal makes the wiring easier to inspect and repair.

[0032] Each of the first connector and the second connector has a connection port on one side;

[0033] The lines connect from one connector to another via the connection ports.

[0034] The present invention has the following beneficial effects:

[0035] This invention, during the connection process, involves the locking blocks of the first and second connectors pressing against a sliding block on one side of the other as they move closer together. Then, as they move forward, the sliding block presses against a moving rod, which in turn outputs gas through an air pump. A portion of the gas enters the air bladder through a gas delivery pipe. Upon completion of the connection, the air bladder expands, compressing the sealing gasket. Even on uneven contact surfaces at the connection point, this ensures the sealing gasket adheres more tightly to the sidewall, preventing it from failing to fit properly and improving the seal's tightness. Furthermore, the sealing process is accelerated during connection, with slow inflation adapting better to various connection environments.

[0036] This invention achieves this by having the first and second connectors press against each other's movable parts when they move closer together during the connection process. Then, they move forward, causing the movable parts to press against the end of the wiring tube and move the wiring tube. After the connection is completed, a portion of the wiring groove on the wiring tube is hidden inside the fixing ring, and the remaining wires are tightened to fill the wiring groove, thus hiding any gaps in the wiring groove. The remaining wires fill the wiring groove, and the wiring groove is immediately and completely sealed after the connection is completed, thus sealing the wiring groove in a timely manner.

[0037] This invention allows the first connector and the second connector to be combined into a single connector. The first connector and the second connector are symmetrically provided with locking blocks and slots that fit into each other. The two connectors move closer to each other. When the two semi-rotating disks come into contact with each other, the semi-rotating disks begin to rotate. The lever is driven to rotate, and the third telescopic rod and the second return spring are extended by the lever, dividing the connector into two areas. This allows the circuits to be located in two separate areas without affecting each other. Combined with the circuit sealing, this improves the protection of the circuits.

[0038] This invention utilizes a mechanism where, as the two connectors move closer together, the locking blocks of the first and second connectors press against a sliding block on one side of the other. Then, as they move forward, the sliding block presses against a moving rod, which, in conjunction with an air cylinder, outputs gas. A portion of the gas enters the cleaner through a delivery pipe. During connection, a semi-rotating disc rotates, causing the cleaner to rotate. Several air jets are positioned on one side of the cleaner to thoroughly clean both the first and second connectors before connection is complete. This allows for cleaning of the connector's interior during connection and completes cleaning simultaneously after connection, improving the timeliness of the cleaning process.

[0039] This invention allows for the removal of the first and second connectors by rotating the handles of two levers and moving them in opposite directions. The enlarged wiring groove facilitates connector removal, and the combined effect of wiring seals makes the wiring easier to inspect and repair.

[0040] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0072] Each of the first connector 110 and the second connector 120 has a connection port 310 on one side.

[0073] The steps for using the well-sealed coupler connector of the present invention are as follows:

[0074] connect:

[0075] The first connector 110 and the second connector 120 can be combined into a connector head. The first connector 110 and the second connector 120 are respectively symmetrically provided with locking blocks and locking slots that fit with each other. The two connectors move closer to each other. When the two semi-rotating disks 1701 come into contact with each other, the semi-rotating disks 1701 start to rotate, the lever 1703 is driven to rotate, and the third telescopic rod 1704 and the second return spring 1705 are extended by the lever 1703.

[0076] After full connection, the semi-rotating disk 1701 maintains its rotation direction in reverse, and is repositioned to its initial state by the tension of the second return spring 1705 and lever 1703, thus forming a connection;

[0077] Circuit sealing:

[0078] During the connection process, when the two connectors move closer to each other, the locking blocks of the first connector 110 and the second connector 120 press against the moving part 1604 on the other side, and then move forward, causing the moving part 1604 to press against the tail end of the line tube 1404 and causing the line tube 1404 to move. After the connection is completed, a part of the line groove 1405 on the line tube 1404 will be hidden in the fixing ring 1401, and the remaining wires will be tightened to fill the line groove 1405.

[0079] Cleaning:

[0080] During the connection process, when the two connectors move closer to each other, the locking blocks of the first connector 110 and the second connector 120 press against the sliding block 1603 on the other side, and then move forward. The sliding block 1603 presses against the moving rod 1303 to move. The moving rod 1303 cooperates with the air cylinder 1304 to output gas. Part of the gas enters the cleaner 1503 through the delivery pipe 1501. Then, during the connection, the semi-rotary disk 1701 rotates, driving the cleaner 1503 to rotate. Several jet nozzles are set on one side of the cleaner 1503 to thoroughly clean the first connector 110 and the second connector 120 before the connection is completed.

[0081] Sealing at the joint:

[0082] During the connection process, when the two connectors move closer to each other, the locking blocks of the first connector 110 and the second connector 120 press against the sliding block 1603 on the other side, and then move forward. The sliding block 1603 presses the moving rod 1303 to move. The moving rod 1303 cooperates with the air pump 1304 to output gas. The other part of the gas enters the air bag 1301 through the air supply pipe 1305. When the connection is completed, the air bag 1301 expands and squeezes the sealing gasket 1302, so that the sealing gasket 1302 is more tightly attached to the side wall of the connection.

[0083] Disassembly:

[0084] When disassembly is required, rotate the handle 230 of the two levers 1703, and then move the first connector 110 and the second connector 120 in opposite directions to disassemble the first connector 110 and the second connector 120, and enlarge the wiring slot 1405.
