[0003] Most general connectors use a threaded connection and locking method to connect the plug and the socket. The threaded connection makes the connector plug and the socket pressed against each other. Conductors are installed in the plug and the socket of the connector. When the plug and the socket of the connector are threadedly connected to press against each other, the conductors in the plug and the socket abut against each other to allow current to flow.

[0030] Reference Figure 1 The embodiment of the present application discloses a quick connector, including a male head and a female head that cooperate with each other, the male head includes a male head shell and a male head conductor, the male head shell is hollow inside and has a docking chamber, and the male head conductor passes through the male head shell and extends into the docking chamber. When the male head and the female head are docked, the outer wall of the female head is threadedly connected to the docking chamber so that the conductor of the female head abuts against the conductor of the male head to achieve current conduction.

[0031] The male housing comprises a connecting housing, a main housing, a safety spring and a fixing member.

[0032] The main housing is sleeved on the outer side of the connecting housing and can slide on the connecting housing. An abutment ring is provided on the outer side of the end of the connecting housing, and a spring placement groove is formed between the connecting housing and the main housing. The outer side of the abutment ring and the inner wall of the spring placement groove are both threaded, so that the main housing and the connecting housing can be threadedly matched. When the connecting housing and the main housing need to move relative to each other, the threads between the connecting housing and the main housing are first released, and then the main housing is driven to slide.

[0033] The safety spring is located in the spring placement groove, and is used to drive the main housing to slide along the length direction of the connecting housing. One end of the safety spring abuts against the main housing, and the other end of the safety spring abuts against the abutment ring.

[0034] A fixing groove is provided on the main housing, and a fixing member is installed in the fixing groove and is used to lock the main housing to the connecting housing. The fixing member includes a lever member, a driving assembly and a locking assembly.

[0035] The lever member is rotatably mounted in the fixed groove through a torsion spring, and the lever member has a driving end and a locking end at both ends of the rotation center. The driving assembly is connected to the driving end and is used to drive the lever member to rotate. The locking assembly is connected to the locking end and is used to lock the connection housing. When the driving assembly drives the lever member to rotate, the locking end of the lever member can drive the locking assembly to move.

[0036] The driving assembly includes a pressing block, a driving block, and a reset spring connecting the pressing block and the driving block. The pressing block is inserted into the main housing and slides into the fixed groove. The lever member is provided with a waist-shaped groove at the driving end, and the driving block slides in the waist-shaped groove. The driving block is provided with an arc surface on the side close to the waist-shaped groove. When the driving block drives the lever member to rotate, the contact points between the arc surface and the lever member are less than those between an ordinary plane, so that the friction between the arc surface and the lever member is less than the friction between an ordinary plane and the lever member, and the lever member is not easy to cause the driving block to deviate when rotating.

[0037] The return spring is located between the pressing block and the driving block and is used to drive the pressing block to always have a tendency to extend out of the main housing. When the pressing block is pressed, the return spring drives the lever member to rotate. When the lever member rotates to the right position, the return spring releases elastic potential energy to drive the pressing block to return and extend out of the main housing.

[0038] One end of the return spring is connected to the pressing block through a connecting gasket, and a rotation fixing groove for fixing the connecting gasket is provided on the pressing block, and a fixing block for fixing the connecting gasket is provided on the bottom surface of the rotation fixing groove, the cross-section of the fixing block is L-shaped and has a locking portion, and a rotation groove for rotationally cooperating with the fixing block is provided on the side of the connecting gasket close to the pressing block, and the cross-section of the rotation groove is L-shaped, and the rotation groove includes an entry channel and a locking channel, the entry channel is located on the side of the connecting gasket close to the pressing block and has the same size as the locking portion, and the locking channel is located on the side of the entry channel away from the pressing block and is interconnected with the entry channel, and when the locking portion moves to the entry channel and rotates, the locking portion is located in the locking channel, thereby fixing the connecting gasket in the rotation fixing groove.

[0039] The other end of the reset spring is connected to the driving block through a fixed gasket. A clip for clamping and fixing the fixed gasket is circumferentially installed on one end of the driving block away from the arc surface. The clip is rotatably connected to the driving block through a torsion spring, and at least two clips are provided. A clamping groove for clamping and fixing the clip is provided on the fixed gasket. A guide slope for guiding the clip to clamp into the clamping groove is provided on the side of the clip close to the fixed gasket, so that the fixed gasket can be conveniently installed and fixed on the driving block. A limit plate for preventing the clip from rotating excessively when the clip is rotated and reset by the torsion spring is provided on the side of the clip close to the fixed gasket. When the fixed gasket is installed, the fixed gasket slides along the guide slope and drives the clip to rotate in a direction away from the fixed gasket. When the clip is aligned with the clamping groove, the clip is clamped into the clamping groove under the reset action of the torsion spring to fix the fixed gasket on the driving block.

[0040] Furthermore, a connection cover for fixing the connection gasket is provided on the pressing block, and the connection cover is threadedly connected to the pressing block, thereby reducing the probability of the connection gasket falling off and further fixing the connection gasket. A driving ring is sleeved on the outside of the fixed gasket, and a clamping block for facilitating the threaded connection of the connection cover is provided on the outside of the driving ring. A rotating clamping groove for clamping with the clamping block is provided on one side of the connection cover close to the fixed gasket. When the clamping block corresponds to the rotating clamping groove, the clamping block is clamped into the rotating clamping groove and the driving ring is driven to rotate to fix the connection gasket.

[0041] The locking assembly includes a sliding block and a fixed pin. The sliding block is rotatably connected to the locking end of the lever member, and a mounting groove for placing the fixed pin is provided on a side of the sliding block close to the connecting shell. The fixed pin is telescopically slidable in the mounting groove, and a fixed magnet is provided on the inner bottom surface of the mounting groove. A sliding magnet is installed on a side of the fixed pin close to the fixed magnet. The sliding magnet and the fixed magnet repel each other magnetically to drive the fixed pin to always have a tendency to extend out of the mounting groove.

[0042] The connecting housing is provided with a gear slot along the length direction for inserting the locking assembly and locking the connecting housing. The gear slot is annular and has two gear slots, and includes a locking gear position and an unlocking gear position. When the safety spring drives the main housing to move, the sliding block of the fixing member can switch between the locking gear position and the unlocking gear position.

[0043] When the sliding block is in the locking position, the connecting shell and the main shell form a blocking ring at the insertion port of the female shell for blocking the male head from mating with the female head. When the sliding block is in the unlocking position, the connecting shell and the main shell are parallel to each other at the insertion port of the female shell, thereby enabling the male head to be mated and connected with the female head.

[0044] The end of the fixing pin away from the sliding magnet has an arc-shaped surface. When the connecting shell and the main shell need to move relative to each other, the sliding block releases the lock on the connecting shell, and the arc-shaped surface of the fixing pin is retracted into the installation groove through the extrusion of the connecting shell. When the fixing groove is aligned with the gear groove, the fixing pin is stuck into the gear groove under the repulsive force of the sliding magnet and the fixed magnet to achieve pre-fixation of the connecting shell.

[0045] Furthermore, the pressing block is provided with a limiting block for limiting the pressing block in the main housing, the limiting block is located on the side of the pressing block close to the connecting housing, and the fixing groove has a limiting portion abutting against the limiting block. A limiting sleeve for locking the pressing block is provided on the main housing, and a limiting groove for the limiting sleeve to be rotated and inserted is provided on the pressing block, and an anti-skid pattern is provided on the outer side of the limiting sleeve for preventing slipping, so that the limiting sleeve can be rotated conveniently. In this embodiment, two limiting grooves are provided on the pressing block, so that the limiting sleeve can be inserted into the limiting grooves when rotating left and right to lock the pressing block, thereby increasing the stability of the connector.

[0046] The female head includes a base and a female head shell. A bearing assembly for reducing wear of the connection housing is arranged on the base. A mounting annular groove for mounting the bearing assembly is provided on one side of the base close to the female head shell. When the connection housing and the female head shell are threadedly connected, the connection housing and the bearing assembly approach and abut each other, and the bearing assembly rotates with the connection housing until the connection housing presses the bearing assembly, thereby reducing the friction between the connection housing and the base during rotation and pressing when the connection housing approaches the base, so as to increase the service life of the connection housing. In this embodiment, the bearing assembly uses a pressure bearing.

[0047] The operation process of a quick connector according to an embodiment of the present invention is as follows: 1. Rotate the limit sleeve to unlock the pressing block; 2. Press the pressing block to drive the lever member to rotate, and the sliding block exits the locking position under the drive of the lever member; 3. Drive the main housing to slide in a direction away from the female head. When the main housing slides, the fixing pin at the locking position is squeezed by the connecting housing to retract into the installation groove. When the thread on the inner wall of the main housing abuts the thread of the abutting ring, rotate the main housing so that the main housing and the connecting housing are locked by the thread. 3. Align the connecting housing with the female housing and insert them so that the main housing abuts against the bearing assembly. Release the pressing block and control the rotation of the main housing to make the connecting housing rotate and slide toward the female housing. The threads on the inner wall of the connecting housing are matched with the threads on the outer side of the female housing to connect. 4. Insert the fixing pin into the unlocking position, indicating that the male and female heads are about to be connected. Continue to rotate the main housing. When the connecting housing presses the bearing assembly, the sliding block is inserted into the gear slot of the unlocking position, indicating that the connection between the male and female heads is completed.

[0048] Based on the same inventive concept, an embodiment of the present invention provides an exception handling method for a quick connector, comprising: Step S100: obtaining a humidity detection value in the connector; The humidity detection value refers to the humidity value in the connector, and the parameter obtained by detecting the humidity sensor preset in the connector is used as the humidity detection value.

[0049] Step S101: matching the humidity detection value with the preset detection point to determine the humidity distribution position; The detection point refers to the position point where the humidity value in the connector is detected, which is formed by the operator's pre-setting and storage. The humidity distribution position refers to the position where the humidity detection value exists in the connector. The position where the humidity detection value is detected by the humidity sensor coincides with the detection point as the humidity distribution position.

[0050] Step S102: determining whether to continue acquiring the humidity detection value or calculating the difference between the humidity detection value and the reference humidity value according to the difference between the humidity detection value and the reference humidity value, and defining the difference as a humidity deviation value; The reference humidity value refers to the humidity value of the connector under normal conditions, which is set and stored by the operator in advance. The humidity deviation value refers to the deviation between the humidity detection value and the reference humidity value. When the humidity detection value is not greater than the reference humidity value, it means that the humidity in the connector is within the normal range, and the humidity detection value continues to be obtained. When the humidity detection value is greater than the reference humidity value, it means that the humidity in the connector is beyond the normal range, and the difference between the humidity detection value and the reference humidity value is calculated and used as the humidity deviation value.

[0051] Step S103: determining the number of ultrasonic devices to be used or outputting a preset warning prompt message according to whether the humidity deviation value falls within a preset reference humidity deviation range; The reference humidity deviation range refers to the reference range corresponding to the use of the ultrasonic device, which is formed after being pre-set and stored by the operator. The ultrasonic device refers to a device installed in the female head and used to remove the humidity in the connector. The ultrasonic device includes an ultrasonic transducer and a water-absorbing cotton. The early warning prompt information refers to the prompt information for warning of the abnormality of the connector, which is formed after being pre-set and stored by the operator. The number of uses refers to the number of ultrasonic devices used. When the humidity deviation value does not fall into the reference humidity deviation range, it means that the ultrasonic device cannot remove the humidity in the connector, and then the early warning prompt information is output. When the humidity deviation value falls into the reference humidity deviation range, it means that the ultrasonic device can remove the humidity in the connector, and the number of uses is matched from the preset ultrasonic database through the humidity deviation value. The ultrasonic database stores the number of ultrasonic devices used corresponding to the humidity deviation value and the power of the ultrasonic device. The ultrasonic database is set manually and will not be repeated here. In this embodiment, three ultrasonic devices are provided.

[0052] Step S104: determining the activation sequence number corresponding to the ultrasonic device according to the humidity distribution position; The start-up sequence number refers to the sequence number of starting the ultrasonic device, and the parameters corresponding to the start-up of the ultrasonic device at the humidity distribution position are used as the start-up sequence number.

[0053] Step S105: determining the adjustment power according to the humidity deviation value and controlling the ultrasonic device corresponding to the start sequence number to perform dehumidification.

[0054] The regulated power refers to the power of the ultrasonic device after adjustment, and the regulated power is matched from the ultrasonic database through the humidity deviation value. By adjusting the power to control the ultrasonic device corresponding to the start sequence number to dehumidify, the probability of the humidity in the connector causing a fault in the transmission of the connector electrical signal can be reduced.

[0055] In step S101 shown above, in order to further ensure the rationality of the method after determining the humidity distribution position, it is necessary to perform further separate analysis and calculation on the method after determining the humidity distribution position, which is specifically described in detail through the following steps.

[0056] Also included are methods after the moisture distribution location is determined: Step S200: calculating the distance between the humidity distribution position and the installation position of the ultrasonic device as the adsorption distance; The installation position refers to the position where the ultrasonic device is installed, which is pre-set and stored by the operator. The adsorption distance refers to the distance at which the ultrasonic device adsorbs water droplets, which is calculated as the distance between the humidity distribution position and the installation position of the ultrasonic device.

[0057] Step S201: Arrange the adsorption distances in reverse order, and use the installation position corresponding to the ultrasonic device with the smallest adsorption distance as the adsorption position; The adsorption position refers to the installation position corresponding to the ultrasonic device capable of adsorbing water droplets. The adsorption distances are arranged in reverse order, and the installation position corresponding to the ultrasonic device with the smallest adsorption distance is selected as the adsorption position.

[0058] Step S202: determining the vibration power according to the humidity deviation value and the adsorption distance; The vibration power refers to the vibration power of the vibration device, and the vibration power is matched from a preset vibration database through the humidity deviation value and the adsorption distance. The vibration database stores the power of vibrations corresponding to different humidity deviation values ​​and adsorption distances. The vibration device refers to a micro vibrator used to control the movement of water droplets toward the ultrasonic device. In this embodiment, a plurality of micro vibrators are provided on the base. When it is necessary to control the movement of water droplets, the micro vibrators generate vibrations to control the water droplets to move in the relative direction of the vibration generation. The directions of vibrations generated by the plurality of micro vibrators are used to form a path for the movement of water droplets, so that the movement of water droplets can be controlled by the vibration device.

[0059] Step S203: determining the vibration direction according to the adsorption position and the humidity distribution position; The vibration direction refers to the direction in which the vibration device causes the water droplets to move. The vector angle is determined by comparing the straight line between the adsorption position and the humidity distribution position with the reference horizontal line preset by the vibration device, and then the parameters of the corresponding direction are retrieved from the vector angle as the vibration direction.

[0060] Step S204: controlling the vibration device preset on the connector to vibrate according to the vibration power and the vibration direction.

[0061] By controlling the vibration device to vibrate with vibration power and vibration direction, the water droplets can be moved to the ultrasonic device, thereby removing the humidity in the connector.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
