Description

Technical Field

[0001] The invention belongs to the technical field of vacuum furnace thermocouple installation, and in particular relates to a button unlocking end face sealing connector. Background Art

[0002] Temperature is the most basic physical quantity in life and production, which represents the degree of hotness or coldness of an object. Temperature monitoring and control are also widely used in various fields of social life. In many production processes, temperature measurement and control are directly related to major economic indicators such as safe production, improving production efficiency, ensuring product quality, and saving energy. As an important part of the nuclear waste treatment system in the nuclear power field, the temperature of the vacuum furnace is one of the important indicators to ensure the production quality of the vacuum furnace equipment, and it is also an important parameter to ensure the safety of the vacuum furnace equipment.

[0003] In order to avoid the escape of radioactive materials, the vacuum furnace used in the nuclear waste treatment system is usually placed in a sealed glove box, and the thermocouple used to measure the temperature in the furnace is installed on the furnace body through the KF flange. The traditional vacuum furnace thermocouple is installed on the vacuum furnace KF flange, and the metal sealing gasket is compressed by the installation screws to achieve sealing, thereby ensuring the vacuum degree of the vacuum furnace. This structure is resistant to high temperature and radiation, and can better meet the application environment requirements of the vacuum furnace.

[0004] In the related prior art, the thermocouple is installed on the furnace body through the KF flange (or simply flange) and screws, which can well meet the use requirements in terms of design and function realization. However, after the application of engineering and the actual operation of the thermocouple, it is found that on the one hand, due to the high temperature of the measurement environment, the thermocouple is easily damaged and needs to be replaced quickly when a failure occurs; on the other hand, the thermocouple's own measurement cycle is 6 months, and even if it is not damaged, it needs to be removed regularly for calibration and measurement.

[0005] However, since the entire furnace body needs to be sealed and protected and placed in a glove box, operation and maintenance operations are all performed with the gloves built into the glove box. In addition, the glove box is 2.5 meters high, the gloves are 1.75 meters above the ground, and the furnace body is located in the middle of the glove box. When a failure occurs or measurement is required, it is extremely difficult to remove, install and replace the thermocouple. The life of the furnace body itself is much longer than the damage / measurement cycle of the thermocouple. Therefore, the glove box needs to be disassembled frequently, and even the operator needs to wear protective clothing to operate after the glove box is disassembled (seriously increasing the risk of personnel exposure) to achieve maintenance and replacement of the thermocouple, which greatly affects production efficiency and production safety (risk of radioactive material escape). The owner is very dissatisfied with the application effect of the existing products. Summary of the invention

[0006] The purpose of the present invention is to solve the above-mentioned problems existing in the prior art and to provide a button-unlocked end face sealing connector. Through structural optimization and improvement, the device can directly achieve locking and unlocking of the head seat insertion part at the glove box by using a tool pliers and a button. By achieving end face sealing, the friction caused by the radial sealing ring during the insertion process is avoided, and the head seat can be unlocked without disassembling the glove box. There is no sense of pause during the operation process, which not only greatly reduces the operating difficulty of the operator, but also reduces the safety exposure risk of the operator.

[0030] Compared with the prior art, the present invention has at least the following beneficial effects:

[0031] First, the present invention improves the structure, and realizes the end face sealing after the head seat is docked by cooperating the sealing surface I of the movable part with the sealing surface II of the socket shell. At the same time, the movable part can be pushed to move in the axial direction by the pressing part, so as to realize the end face unsealing when the head seat is unlocked.

[0032] Secondly, this solution also includes a thermocouple. Since the thermocouple is integrated with the plug housing, during the installation and replacement of the thermocouple, the thermocouple does not contact the movable parts or the socket housing, and the end faces are sealed between the head seats, so there is no sense of jerk during the plugging and unplugging process. During the installation or unlocking process, the thermocouple itself is not subjected to additional force, so it is not easy to cause damage to the thermocouple. Therefore, the connector of this solution can achieve rapid separation between the head seats, which is convenient for removal and maintenance and replacement. It not only greatly reduces the disassembly and assembly cost and time of the original thermocouple installation structure, but also effectively improves production efficiency and reduces production risks.

[0067] The present invention is described in detail below by means of exemplary embodiments. However, it should be understood that, without further description, elements, structures and features in one embodiment may also be beneficially combined in other embodiments.

[0068] It should be noted that, unless otherwise defined, the technical terms or scientific terms used herein shall have the usual meanings understood by persons with ordinary skills in the field to which the invention belongs. The words "one", "an" or "the" and the like used in the patent application specification and claims of the present invention do not express quantitative limitations, but indicate the existence of at least one. Words such as "include" or "comprise" indicate that the elements or objects appearing before "include" or "comprises" include the elements or objects listed after "include" or "comprises" and their equivalents, but do not exclude other elements or objects with the same function.

[0069] As shown in the figure, this embodiment provides a push-button unlocking end-face sealing connector, including a connector plug 100 and a connector socket 200 adapted thereto, wherein the connector plug 100 includes a plug housing 1, and the connector plug 100 forms a cavity Ⅰ11 along the central axis direction, and a movable part 2 is arranged inside the cavity Ⅰ11, and the movable part 2 can move in the axial direction in the cavity Ⅰ11, and the pressing part 3 is arranged on the side wall of the cavity Ⅰ11 in a radially movable manner, and the outer end face of the pressing part 3 can protrude from the cavity Ⅰ11 to the outside to facilitate the pressing operation, and a sealing surface Ⅰ21 is arranged on one side of the head end of the movable part 2. In this embodiment, the connector plug 100 and the connector socket 200 respectively use their plug-in ends as their head ends. The pressing piece 3 extends into one end of the cavity Ⅰ11 and contacts the movable piece 2, and presses the pressing piece 3 toward the inside of the cavity Ⅰ11, thereby pressing the movable piece 2 to realize the movement of the movable piece 2 along its axial direction. The connector socket 200 includes a socket housing 4, and the head end of the socket housing 4 is formed with a sealing surface Ⅱ41 adapted to the sealing surface Ⅰ21. The sealing surface Ⅱ41 can abut against the sealing surface Ⅰ21 to realize the head seat sealing, and the sealing surface Ⅱ41 can be separated from the sealing surface Ⅰ21 to realize the head seat sealing (sealing, that is, the sealing between the head seats is released). This scheme realizes the effect of end face sealing or end face sealing through the axial movement of the movable piece 2 between the head seats. Since the end face sealing method is adopted between the head seats, the influence of the plug-in and unplug force factor is avoided, so there will be no sense of stiffness between the head seats during the plug-in and unplug process.

[0070] In a typical embodiment of the present invention, the movable part 2 can be implemented as follows: the movable part 2 adopts a rotating body, and the head end face of the movable part 2 is provided with a sealing surface Ⅰ21, and the sealing surface Ⅰ21 is perpendicular to the axial direction of the movable part 2. The movable part 2 is also provided with a lifting cover 22 near the head end, and the lifting cover 22 is connected to the circumferential edge of the sealing surface Ⅰ21, and the lifting cover 22 adopts a conical surface structure. At least one annular groove Ⅰ25 is provided on the sealing surface Ⅰ21 and / or the sealing surface Ⅱ41, and a sealing member Ⅰ24 is installed in the annular groove Ⅰ25. The sealing member Ⅰ24 can adopt an elastic O-ring, and the sealing surface Ⅰ21 and the sealing surface Ⅱ41 are squeezed by the sealing member Ⅰ24 to achieve end face sealing. Considering the convenience of replacing the sealing member Ⅰ24, it is preferred that the sealing member Ⅰ24 is arranged in the annular groove Ⅰ25 of the sealing surface Ⅰ21, so that when the connector plug 100 is removed, the sealing member Ⅰ24 can be conveniently replaced.

[0071] This solution also takes into account that there is a matching gap between the movable part 2 and the inner wall of the cavity Ⅰ11. In order to ensure the sealing effect, the outer cylindrical surface of the movable part 2 and the inner wall of the cavity Ⅰ11 are used as matching sealing surfaces, and at least one side of the outer cylindrical surface of the movable part 2 and the inner wall of the cavity Ⅰ11 is provided with an annular groove Ⅱ26, and the annular groove Ⅱ26 is installed with a sealing member Ⅱ27, and the sealing member Ⅱ27 can be an elastic O-ring. Also, considering the convenience of replacing the sealing member Ⅱ27, the outer cylindrical surface of the movable part 2 is provided with an annular groove Ⅱ26, and the sealing member Ⅱ27 is installed in the annular groove Ⅱ26 of the movable part 2. After the movable part 2 is taken out from the inside of the cavity Ⅰ11, the replacement of the sealing member Ⅱ27 can be facilitated.

[0072] In this scheme, in order to ensure the assembly effect of the movable part 2 after installation and provide a certain pre-tightening force for the assembly of the movable part 2, a circle of stop platform II23 is formed on the circumferential edge of the outer cylindrical surface of the movable part 2, and a stop platform III12 is formed on the inner wall of the plug housing 1. The stop platform II23 cooperates with the tail end of the stop platform III12. On the one hand, it can be ensured that after the movable part 2 is assembled, the elastic part I6 has a certain installation pre-tightening force. At the same time, the stop platform III12 forms a stop and limit effect on the movement of the movable part 2 in the first axial direction. The first axial direction refers to the direction of the plug housing 1 along the axial direction from the tail end to the head end (plug end). In order to provide the movable part 2 with a preload force for end face sealing with the socket housing 4 and to facilitate the resetting of the movable part 2, an elastic part Ⅰ6 is provided at the tail end of the movable part 2, one end of the elastic part Ⅰ6 abuts against the inner wall of the plug housing 1, and the other end of the elastic part Ⅰ6 is sleeved on the tail end of the movable part 2 and abuts against the tail end stop platform Ⅰ210 of the movable part 2. The elastic part Ⅰ6 is used to provide the movable part 2 with a preload force for end face sealing. In this scheme, the elastic part Ⅰ6 can be a corrugated spring. When the movable part 2 moves axially toward the tail end, the elastic part Ⅰ6 will be gradually compressed and accumulate elastic force for resetting the movable part 2 toward the head end.

[0073] In this embodiment, the plug housing 1 includes an end housing 13 and a connecting sleeve 14 connected to the end housing 13, and the rear end of the connecting sleeve 14 is connected to the end housing 13. Specifically, in order to facilitate the disassembly and assembly of the movable part 2, the end housing 13 and the connecting sleeve 14 can be connected by a threaded connection. For example, the head end of the end housing 13 is provided with an external thread, and the rear end of the connecting sleeve 14 is provided with an internal thread. The assembly of the plug housing 1 is achieved by screwing together the internal and external threads. Specifically, the stop platform III 12 is provided on one side of the rear end of the connecting sleeve 14, and a movable gap 15 in the axial direction of the stop platform II 23 for the movable part 2 is formed between the stop platform III 12 and the head end of the end housing 13.

[0074] In this solution, the end shell 13 is formed with a mounting cavity along the axial direction, and the connecting sleeve 14 is formed with a connecting cavity along the axial direction. After the end shell 13 and the connecting sleeve 14 are docked and combined, the mounting cavity and the connecting cavity are docked to form a complete cavity Ⅰ11. Holes Ⅰ141 are relatively arranged on the side walls of the connecting sleeve 14. The purpose of setting the hole Ⅰ141 is to install the pressing piece 3. A mounting groove Ⅰ143 is circumferentially arranged on the hole Ⅰ141. The mounting groove Ⅰ143 is used to install and place the pressing piece 3. A circular ring sleeve Ⅰ142 is arranged between the mounting groove Ⅰ143 and the hole Ⅰ141.

[0075] In one embodiment of the present invention, the pressing member 3 adopts the following implementation mode: the pressing member 3 includes a pressing plate 36 located at one end of the outer side, and a circular ring sleeve II 34 and a central protrusion 33 are arranged on one side of the inner end surface of the pressing plate 36. The central protrusion 33 is located inside the circular ring sleeve II 34, and a mounting groove II 35 is formed between the circular ring sleeve II 34 and the central protrusion 33. The function of the mounting groove II 35 is to accommodate the elastic member II 7. In this solution, the elastic member II 7 can be a corrugated spring, such as Figure 6 , 10 As shown, the annular sleeve I 142 at the hole I 141 is arranged correspondingly to the notch of the installation groove II 35 to seal the elastic member II 7 inside. The annular sleeve II 34 is arranged correspondingly to the notch of the installation groove I 143. The annular sleeve II 34 and the installation groove I 143 are provided with a guide structure for the pressing action of the pressing member 3. The setting method of the guide structure is described as follows: Figure 6 and Figure 7The outer wall of the annular sleeve II 34 is provided with a guide groove 38, and the side wall inside the installation groove I 143 is provided with a guide block 144 that cooperates with the guide groove 38, so as to achieve the guiding effect of the pressing member 3 during the pressing process and ensure the smoothness of the pressing. It should be pointed out that the guiding mechanism of the pressing member 3 can also be set in other forms, for example, a guide groove is provided on the side wall of the installation groove I 143, and a guide block that cooperates with the guide groove is provided on the outer side of the annular sleeve II 34, which can also achieve the guiding effect. In order to ensure the matching effect of the guide groove and the block, avoid interference, and facilitate processing, the root of the guide block 144 is processed with a process arc 145 on both sides. In addition, a stopper 8 is also provided on the outer circumference of the pressing member 3. The stopper 8 is a retaining ring structure, and a through hole 81 is provided in the center thereof. The through hole 81 is used for the pressing plate 36 on the pressing member 3 to be exposed outward. The function of the stopper 8 is to form a stopper for the stopper platform IV37 in the circumference of the pressing member 3. The stopper platform IV37 is located at the circumferential edge position of the outer end surface of the pressing plate 36, so as to limit the pressing member 3 to move in the installation groove I143. When the pressing member 3 is pressed, the annular sleeve I142 enters the installation groove II35 and squeezes the elastic member II7. The elastic member II7 shortens and accumulates the elastic force to reset the pressing member 3. After being pressed, the pressing member 3 enters the plug housing 1 to unlock the head seat; when the external pressing force is eliminated, the pressing member 3 is reset outward to the original state by the reset force of the elastic member II7. Therefore, the pressing member 3 has at least two working positions. In the first working position, the pressing member 3 enters the plug housing 1 after being pressed to unlock the head seat. In the second working position, the pressing member 3 is reset outward to the original state by the reset force of the elastic member II7.

[0076] In this solution, a top head 31 is provided on the central protrusion 33. Preferably, the top head 31 is located on one side of the central protrusion 33. The portion where the top head 31 contacts the lifting cover 22 is a curved edge vertex 311 of an arc-shaped structure. The curved edge vertex 311 is formed by the junction of a cylindrical surface on one side of the top head 31 and an end surface on one side. The curved edge vertex 311 adopts an arc chamfered structure. With such a design, the curved edge vertex 311 contacts the conical surface structure of the lifting cover 22, thereby realizing the mutual pushing effect between the pressing member 3 and the movable member 2. The purpose of such a design is that the curved edge vertex 311 contacts the lifting cover 22, and the curved edge vertex and the conical surface adopt a point-to-point structure. The contact mode can minimize the contact area between the two, and the contact positions are all smooth curved surfaces. Therefore, the relative friction between the two when the top head 31 slides on the lifting surface 22 can be effectively reduced, so that the pressing action of the pressing piece 3 is not blocked and is more labor-saving. During the inward pressing action of the pressing piece 3, as the pressing piece 3 moves toward the inside of the cavity Ⅰ11, the pushing point of the curved edge top angle 311 will move toward the center of the cone on the lifting surface 22. In this way, the pressing piece 3 can push the movable part 2 to gradually move toward the tail end of the cavity Ⅰ11, so that the sealing surface Ⅰ21 and the sealing surface Ⅱ41 are released.

[0077] In the present solution, in order to further ensure the sealing state, on the basis of the above-mentioned end face sealing, it is also necessary to lock between the head seats, so as to cooperate with the above-mentioned end face sealing technology. When the head seats are plugged in or out, they need to be locked or unlocked to ensure the plug-in effect. In order to further improve the convenience of locking and unlocking, the connector socket 200 is also provided with a locking member 5 at a circumferential position close to its head end. The locking member 5 can cooperate with the pressing member 3 to achieve the locking state between the head seats. At this time, the head end sealing surface II41 of the socket housing 4 can be abutted and sealed with the head end sealing surface I21 of the movable part 2. The locking member 5 can also cooperate with the pressing member 3 to achieve the unlocking state between the head seats. At this time, the sealing surface II41 can be separated from the sealing surface I21 and unsealed.

[0078] In this solution, a hook portion 32 is further provided on the central protrusion 33 of the pressing member 3, the fixed end of the hook portion 32 is connected to the central protrusion 33, and a hook claw 321 is provided at the free end of the hook portion 32, which extends into the hanging cavity 52 of the locking member 5 through the hook claw 321 to achieve matching hanging connection with the hanging plate 511. A clamping inclined surface 323 is formed on one side of the head end of the hook portion 32, so as to guide and save effort in the clamping connection between the hook portion 32 and the hanging plate 511, and avoid the plug-in jamming phenomenon caused by insufficient clamping force during the plug-in process of the head seat.

[0079] In a typical embodiment of the present invention, the connector socket 200 includes a socket housing 4 and a locking member 5 arranged on the outside of the socket housing 4 near its head end, the pressing member 3 cooperates with the locking member 5 to realize head seat locking, the tail end of the socket housing 4 is provided with a connecting flange 43, the socket housing 4 is provided with a cavity III 42 along the central axis direction, the head end face of the socket housing 4 is provided with a sealing surface II 41 around the port of the cavity III 42, the inner side of the port of the cavity III 42 is provided with a reinforcement portion, the reinforcement portion is located on the back side of the sealing surface II 41 to increase the contactable sealing area of ​​the sealing surface II 41 and enhance the strength of the sealing surface at the same time, the role of the sealing surface II 41 is to achieve sealing with the sealing surface The cover Ⅰ21 is abutted and sealed; the locking part 5 adopts a hanging tube sleeve 51, which is a hollow cylindrical structure. The hanging tube sleeve 51 is fixed on the outside of the socket shell 4, and the hanging tube sleeve 51 includes a large-diameter tube 513 and a small-diameter tube 514 coaxially connected, wherein the small-diameter tube 514 is sleeved on the outer wall of the socket shell 4 and abuts against the mounting platform 45 of the outer wall of the socket shell 4. Preferably, laser welding can be used here to connect the two as one. The gap between the large-diameter tube 513 and the socket shell 4 forms a hanging cavity 52, and a hanging plate 511 is provided on the large-diameter tube 513 at the head end of the hanging cavity 52, and the hanging plate 511 is integrally formed with the hanging tube sleeve 51.

[0080] The matching structure of the hook 321 and the hanging plate 511 is explained as follows: a locking surface 322 is provided on the side of the hook 321 facing the rear end of the plug housing 1, and a hanging surface 512 is provided on the side of the hanging plate 511 facing the rear end of the socket housing 4. After the head seat is docked, the locking surface 322 and the hanging surface 512 are correspondingly fitted. When the head seat is separated, the locking surface 322 and the hanging surface 512 are relatively slid and separated by squeezing the pressing piece 3, thereby unlocking the head seat.

[0081] In order to facilitate processing, a connecting block 324 is provided at the fixed end of the hook part 32, and a fixing groove 39 for installing the hook part 32 is processed on the central protrusion 33. The fixing groove 39 is adapted to the shape of the connecting block 324. The connecting block 324 of the hook part 32 is installed in the fixing groove 39 and connected by welding or other means, thereby reducing the difficulty of processing and manufacturing.

[0082] In this solution, a top portion 31 and a hook portion 32 are respectively provided at one end of the inner side of the pressing member 3, wherein the top portion 31 contacts the movable member 2, and the hook portion 32 cooperates with the locking member 5 of the socket housing 4. When the pressing member 3 is pressed, the top portion 31 will push the movable member 2 to release the seal. At the same time, the locking surface 322 of the hook portion 32 and the hanging surface 512 of the hanging plate 511 are unlocked by relative sliding. One pressing action completes the realization of the two functions of sealing release and unlocking, which greatly improves the convenience of operation. Preferably, two pressing members 3 are provided and are relatively arranged on the side walls of the cavity Ⅰ11. It is convenient to press from both sides of the plug housing 1. For example, by clamping the pressing member 3 from both sides with a tool pliers, the pressing members 3 on both sides will shrink inward along the radial direction of the connector at the same time, and the operation difficulty is relatively low.

[0083] This solution also includes a thermocouple 9, and the end of the thermocouple 9 inserted into the vacuum furnace is its head end. The cavity III 42 can be connected with the cavity II 28 to form an insertion channel for the thermocouple 9. The head end ceramic packaging shell 91 of the thermocouple 9 extends into the cavity III 42 of the socket housing 4, so as to finally extend into the vacuum furnace for temperature measurement. The encapsulated shell 91 of the thermocouple 9 does not contact the inner wall of the cavity II28 of the movable part 2, so as to form a matching gap between the two, the inner wall of the cavity III42 of the socket housing 4 does not contact the encapsulated shell 91 of the thermocouple 9, and the tail end of the thermocouple 9 is integrated with the end housing 13, for example, the two are fixed as one by laser welding. During the plugging and unplugging of the head seat, due to the end face sealing, the thermocouple 9 will not be disturbed and affected by the movable part 2, and there will be no interference with the socket housing 4. Therefore, during the plugging and unlocking of the head seat, the thermocouple 9 in this scheme is not subjected to force, and there is no sense of jerkiness during the plugging and disassembling process, and it is not easy to be damaged, which can meet the requirement of no sense of jerkiness during the clamping operation by tool pliers. By integrating the thermocouple 9 with the plug housing 1, the head seat can be quickly unlocked and separated, which is convenient for the removal, replacement and maintenance of the thermocouple 9, greatly reducing the disassembly and assembly cost and time of the original structure, improving production efficiency and reducing production risks.

[0084] In order to ensure the sealing requirements of the welding point between the tail end of the thermocouple 9 and the end shell 13, an annular groove III 92 is also provided on the thermocouple 9. By providing a sealing member III 93 in the annular groove III 92, a sealing effect between the thermocouple 9 and the inner cavity of the end shell 13 is achieved. Since in this solution, a good sealing effect is achieved on the tail end side of the movable part 2 through the sealing member II 27 and the sealing member III 93, therefore, in actual application, when the movable part 2 moves axially toward the tail end side of the cavity I 11, it is necessary to consider where the gas inside the sealed space on the tail end side of the cavity I 11 is discharged after being compressed. If there is no unobstructed gas discharge channel or the gas discharge channel is too small (the gap between the head end port of the cavity II 28 and the packaging shell 91 of the thermocouple 9 is too small, it may be difficult to ensure that the gas is discharged smoothly after being compressed), the pressing member 3 presses inward. During the pressing process, the gas in the sealed space will give the movable part 2 a reverse force, and the movable part 2 will encounter greater resistance when moving toward the tail end. Therefore, the head end port of the cavity II28 of the movable part 2 is circumferentially provided with a hole II29, and the hole II29 is located in the inner circle of the sealing part I24. The function of the hole II29 is: when the movable part 2 moves toward the tail end, it is ensured that the air in the cavity on the tail end side of the movable part 2 can be smoothly discharged to the head end through the gap channel formed by the hole II29, so as to avoid the space shrinkage and the gas pressure forming resistance to the movable part 2, so as to ensure that the pressing process is as labor-saving as possible. It should be noted that, as shown in the figure, the tail end port of the cavity II28 is connected to the cavity I11.

[0085] In this embodiment, in order to realize the assembly of the thermocouple 9, the movable part 2 is formed with a cavity II 28 along the central axis, and the two ends of the cavity II 28 are through, which is used to penetrate the thermocouple 9. The movable part 2 and the thermocouple 9 do not contact each other, and the two can realize relative movement without interfering with each other. Preferably, the hole II 29 is an arc-shaped slot formed by the edge of the head end port of the cavity II 28. Such a design ensures the connection effect of the cavity space on both sides of the head end port of the movable part 2, and facilitates the processing of the slot, reduces the resistance formed by external factors to the pressing action, so as to achieve the purpose of labor-saving pressing, and facilitate the clamping operation by tool pliers.

[0086] The operation process of the connector of this scheme is as follows: unlocking and locking operations are realized by tool pliers. When unlocking, the pressing members 3 on both sides of the plug housing 1 are clamped by tool pliers, and the relative sliding separation between the hook part 32 and the locking member 5 is realized to realize unlocking. At the same time, the top head 31 abuts against the start cover 22 of the movable member 2, and the movable member 2 will retreat axially to the tail end side, the elastic member I6 is compressed, and the movable member 2 is separated from the sealing surface II41 of the socket housing 4. The sealing member I24 no longer plays a sealing role, and the locking relationship of the head seat is released. When locking, after the pressing members 3 on both sides of the plug housing 1 are clamped by tool pliers and inserted into place, the tool pliers are released, and the elastic member I6 (while the elastic member II7 assists) drives the pressing member 3 to move to the outside of the plug housing 1, and the locking between the head seats is realized by the cooperation of the hook part 32 and the locking member 5. At the same time, the movable member 2 presses against the sealing surface II41 of the socket housing 4, and the sealing rubber ring there is squeezed to realize the sealing.

[0087] The present embodiment provides a push-button unlocking end face sealing connector. By setting the connector plug 100 and the connector socket 200 to be detachable, not only the two have the separation function, but also the original installation interface of the vacuum furnace is kept unchanged. The connecting flange 43 of the fixed end of the connector socket 200 still adopts the original metal sealing method, and is fixedly connected to the vacuum furnace interface through the connecting piece 44. The connecting piece 44 can be selected with a connecting bolt. After one installation, there is no need to replace the connector socket 200. The movable part 2 inside the connector plug 100 adopts a special rubber that is heat-resistant and radiation-resistant as the sealing material to meet the user's use environment requirements, and each sealing component is designed on one side of the connector plug 100, which can be easily removed and replaced when necessary.

[0088] The design of this solution effectively solves the contradiction between the installation method of conventional thermocouples for vacuum furnaces and their actual application: on the one hand, it is necessary to achieve higher vacuum degree and temperature and radiation resistance requirements, and on the other hand, it is necessary to consider the actual application conditions. In the glove box, the operator's hands cannot reach the installation position, and can only be separated and plugged in by tool pliers. The design of this solution can effectively meet the requirements of clamping both sides by tool pliers. At the same time, the tool pliers can be directly clamped on the pressing piece 3, and then the connector plug 100 is clamped for insertion. During the installation process of this solution, except for the gravity of the thermocouple 9 itself, there is no other structure that causes a sense of suddenness during insertion or separation. (In the existing actual operating environment, it is necessary to consider that it is difficult to apply force in the glove box, and only the palm gripping force can be provided to drive the connector to unlock. Since the thermocouple 9 adopts a ceramic packaging shell, the separation and insertion process will cause the thermocouple 9 to collide with the furnace body of the vacuum furnace, resulting in the ceramic package being broken). The design of this solution effectively solves the above-mentioned technical problems encountered in the actual operating environment. The connector of this solution can be used as a standard part in other thermocouple application scenarios. It can achieve quick separation and replacement, reduce the disassembly and assembly costs and time costs due to thermocouple damage, and reduce production risks.

[0089] In addition to being applicable to the installation field of the above-mentioned vacuum furnace thermocouple 9, this embodiment also provides a push-button unlocking end face sealing connector, which is different from the above-mentioned embodiment in that: it does not include the thermocouple 9, and the push-button unlocking end face sealing technology and connector structure used in conjunction with the above-mentioned connector plug 100 and connector socket 200 are applied to an electrical connector with a pinhole insulator component. The electrical connector includes the above-mentioned connector plug 100 and connector socket 200, and the connector plug 100 and the connector socket 200 are respectively provided with corresponding pinhole insulator components, so as to realize the plug-in and plug-out force-free plug-in mode of the connector end face seal, and at the same time, the head seat seal is released and unlocked by a button (pressing member).

[0090] The present solution provides another push-button unlocking end face sealing connector, which is different from the above-mentioned embodiment in that: the thermocouple 9 is not included, and the push-button unlocking end face sealing technology and connector structure of the above-mentioned connector plug 100 and connector socket 200 used in combination are applied to a liquid-cooled connector for connecting pipelines at the tail end of the plug and socket; the liquid-cooled connector includes a connector plug 100 and a connector socket 200, thereby realizing a force-free plug-in connection method of the end face seal of the liquid-cooled connector to achieve pipeline docking, and at the same time, the head seat seal is released and unlocked by a button (pressing piece).
