Description

Technical Field

[0001] This utility model relates to the field of connector connection technology, and in particular to a connector connection mechanism. Background Technology

[0002] In recent years, with the rapid popularization of new energy vehicles, people's requirements for the range and driving comfort of new energy vehicles have also increased. Therefore, thermal management modules have become a standard feature of new energy vehicles. Since the thermal management module needs to be tested with high-pressure gas (greater than 10 bar) by high-pressure testing equipment during the manufacturing process, the connection between the test pipeline and the product pipeline on the highly flexible high-pressure testing equipment currently uses O-ring seals and bolt locking.

[0003] This method has a simple structure and reliable sealing, but the entire installation and disassembly process requires operators to manually tighten and loosen bolts with the help of tools. This has the following disadvantages: 1) The number of parts that the operator needs to install manually is large, the installation process is complicated, and the labor intensity of workers is high; 2) The installation and disassembly of bolts both require the use of tools, the steps are cumbersome, the time for joint installation and disassembly is long, and it affects production efficiency.

[0004] Therefore, for those skilled in the art, how to design a connector connection mechanism that enables simple assembly and disassembly is a technical problem that urgently needs to be solved. Utility Model Content

[0036] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0037] The terms “center,” “longitudinal,” “lateral,” “length,” “width,” “thickness,” “upper,” “lower,” “front,” “rear,” “left,” “right,” “vertical,” “horizontal,” “top,” “bottom,” “inner,” “outer,” “clockwise,” “counterclockwise,” “axial,” “radial,” and “circumferential” indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the mechanism or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0038] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "fixation," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between the components; they can refer to a direct connection or a connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0039] The present invention will now be described in detail with reference to the accompanying drawings and preferred embodiments. Unless otherwise specified, the following embodiments and features can complement or combine with each other.

[0040] Reference Figures 1-4 As shown, a preferred embodiment of the present invention provides a connector connection mechanism, including a locking component 1, a sealing component 2, and a mounting block 3. The locking component 1 and the sealing component 2 are both disposed on the mounting block 3. One end of the sealing component 2 is used to extend into the pipe hole (not shown) of the target component, and one end of the locking component 1 is used to extend into the mating hole (not shown) of the target component.

[0041] The locking component 1 has a locked state and an unlocked state, and can switch between the two states. In the locked state, the locking component 1 locks the target component, and in the unlocked state, the locking component 1 releases the target component. In actual use, the locking component 1 can be used to fix the connector connection mechanism to the product, ensuring that the entire sealing component 2 will not come off during the entire sealing test of the product.

[0042] It should be noted that the target components here refer to products that require sealing testing, such as components in the thermal management module of new energy vehicles.

[0043] This utility model provides a connector connection mechanism that can be connected to the product through a locking component. It can quickly lock and disassemble the product pipeline without the need for tools, making it convenient to operate, saving time and effort. This can greatly reduce the labor intensity of employees and significantly improve production efficiency.

[0044] Reference Figures 1-5 As shown, a first mounting hole is formed through the mounting block 3. The sealing assembly 2 includes a sealing connecting rod 21 and a sealing connector 22. The sealing connector 22 is used to extend into and be fixed in the pipe hole. The sealing connecting rod 21 extends into one end of the first mounting hole, and the sealing connector 22 extends into the other side of the first mounting hole and connects to the sealing connecting rod 21. The sealing connector 22 can connect to a test pipe connector or a plug 26 (see reference). Figure 4 This is to achieve the product's sealing performance test.

[0045] In one example, the sealing joint 22 may be threaded to the sealing connecting rod 21. In other examples, the sealing connecting rod 21 and the sealing joint 22 may also be fixed by other connection methods, such as snap-fit.

[0046] Furthermore, a first sealing ring 23 is provided between the end of the mounting block 3 and the sealing connecting rod 21 to seal the gap between the mounting block 3 and the sealing connecting rod 21. In addition, a second sealing ring 24 is provided between the sealing joint 22 and the mounting block 3 to seal the gap between the mounting block 3 and the sealing joint 22. The first and second sealing rings 23 work together to provide a buffer, allowing the sealing component 2 to have a certain amount of floating within the mounting block 3. This facilitates the correction of dimensional deviations between the sealing component 2 and the mounting block 3 during machining, as well as dimensional deviations between the sealing component 2 and the product's pipe hole during machining, ensuring that the connector connection mechanism can be quickly connected and locked to the product.

[0047] Furthermore, at least one third sealing ring 25 is provided on the outer surface of the sealing joint 22, the third sealing ring 25 being used to seal the gap between the pipe hole and the sealing joint 22.

[0048] It should be noted that the sealing joint 22 and the sealing connector 21 adopt a separate structure, and the corresponding sealing joint 22 can be replaced according to the size of different pipelines to enhance product compatibility.

[0049] During actual installation, firstly, a sealing connector 22 matching the inner diameter of the product's pipe hole can be selected as needed. After the sealing connector 22 and sealing connecting rod 21 are installed, the sealing connector 22 can be inserted into the product's pipe hole. Since the outer surface of the sealing connector 22 is provided with a third sealing ring 25, the third sealing ring 25 can seal the connection position between the sealing connector 22 and the pipe hole, thereby ensuring that the product is always in a closed environment during testing.

[0050] This application does not limit the number of third sealing rings 25. For example... Figure 4 As shown, to improve the sealing effect of the sealing joint 22, two third sealing rings 25 spaced apart along their own axial direction can be provided on the outer surface of the sealing joint 22. Of course, the third sealing rings 25 on the outer surface of the sealing joint 22 can also be one, three or more.

[0051] It should be noted that the locking component 1 and the sealing component 2 are positioned on the mounting block 3 such that after the sealing component 2 is inserted into the pipe hole of the product, the locking component 1 can be inserted into the mating hole of the product.

[0052] Reference Figure 1 and Figure 2 In one example, the locking component 1 and the sealing component 2 are arranged in parallel to facilitate the connection and mating of the connector connection mechanism with the product.

[0053] Reference Figure 1 and Figure 2 In a preferred embodiment, the number of sealing components 2 is at least two, all sealing components 2 are arranged in parallel, and the inner diameter of the sealing joints of all sealing components 2 is the same or different. That is, multiple sealing joints 22 with the same or different inner diameters can be installed on the joint connection mechanism, and the multiple sealing joints 22 can be adapted to multiple pipe holes with the same or different inner diameters on the product.

[0054] With this configuration, multiple sealing components 2 can be installed on a sealing block 3 at the same time, so that the joint connection mechanism can seal or connect multiple pipe holes at the same time. At this time, the joint connection mechanism can be used for products with multiple pipe holes and can adapt to the situation where the inner diameters of the multiple pipe holes of the product are different.

[0055] When there are multiple sealing components 2, two sealing components 2 can be used individually for single-hole sealing or connection of the product, or they can be used simultaneously for double-hole sealing or connection of the product.

[0056] Specifically, if the inner diameters of the two pipe holes of the product are the same, two sealing joints 22 with the same outer diameter that match the inner diameter of the pipe holes can be selected. If the inner diameters of the two pipe holes of the product are different, two sealing joints 22 with different outer diameters that match the inner diameters of the two pipe holes can be selected respectively.

[0057] As an alternative, there are two sealing components 22, which are symmetrically arranged on both sides of the locking component 1. As another alternative, the two sealing components 2 can also be arranged on the same side of the locking component 1.

[0058] Furthermore, the sealing connecting rod 21 is provided with a first through hole 211, and the sealing joint 22 is provided with a second through hole 221.

[0059] Reference Figure 4 As shown, in a specific embodiment, a sealing member 26 is provided at the end of the second through hole 211. At this time, the sealing member 26 can prevent the second through hole 212 from communicating with the first through hole 211.

[0060] As a specific embodiment, after the sealing joint 22 is connected to the sealing connecting rod 21, the first through hole 211 and the second through hole 212 are connected to conduct a sealing test on the product.

[0061] More specifically, to verify product performance, a sealing test can be performed on the product using the connector connection mechanism, or the sealing connector 22 can be connected to the plugging component 26 to quickly seal the product's pipe holes. If it is necessary to seal the product's pipe holes, the plugging component 26 can be installed at the end of the sealing connector 22. After the sealing connector 22 is connected to the pipe hole, the plugging component 26 can seal the pipe hole.

[0062] If the product needs to undergo a sealing test, the sealing joint 22 can be connected to the sealing connecting rod 21, and the sealing connecting rod 21 can be connected to the high-voltage testing equipment to achieve the connection between the high-voltage testing equipment and the product, and then the product can be tested for sealing through the high-voltage testing equipment.

[0063] Furthermore, the mounting block 3 is also provided with a second mounting hole (unnumbered), and the locking component 1 is used to pass through and fix in the second mounting hole.

[0064] Reference Figure 4 As shown, the locking assembly 1 includes a locking part 11 and a driving part 12. Both a portion of the locking part 11 and at least a portion of the driving part 12 are housed within the mounting block 3. One end of the locking part 11 extends out of the mounting block 3 and is used to insert into the mating hole of the target assembly. The driving part 12 is used to drive the portion of the locking part 11 extending out of the mounting block 3 to expand after the locking part 11 extends into the mating hole, thereby fixing the locking assembly 1 within the mating hole, at which point the locking assembly 1 is in a locked state. The driving part 12 is also used to drive the portion of the locking part 11 extending out of the mounting block 3 to retract after the locking part 11 extends into the mating hole, thereby separating the locking assembly 1 from the mating hole, at which point the locking assembly 1 is in an unlocked state.

[0065] Reference Figure 4 As shown, in a preferred embodiment, the locking part 11 includes a locking piece 111, one end of which is fixed inside the mounting block 3, and the other end of which extends out of the mounting block 3. One end of the locking piece 111 is used to expand radially under the drive of the driving part 12, so that the external thread on the locking piece 111 engages with the internal thread on the mating hole.

[0066] Specifically, the outer wall of the other end of the locking piece 111 has a first thread 1111, and the inner wall of the mating hole has a second thread (not shown). The first thread 1111 is used to engage with the second thread, thereby fixing the locking piece 111 in the mating hole. The locking piece 111 is also used to return to its initial position under the drive of the drive unit 12, so that the first thread 1111 and the second thread are separated. At this time, the locking piece 111 and the sealing joint 22 can be directly pulled out from the product.

[0067] It should be understood that the radial expansion of the locking plate 111 means that one side of the locking plate 111 moves away from the ejector pin 121, thereby making the locking plate 111 contact and fix with the internal thread of the product mating hole.

[0068] Preferred, refer to Figure 4 The drive unit 12 includes a push pin 121 and a first return spring 122. The first return spring 122 and a portion of the push pin 121 are disposed within the mounting block 3. The first return spring 122 is connected to or abuts against the push pin 121 and is used to drive the push pin 121 to return to its original position after the push pin 121 has moved. The push pin 121 abuts against the portion of the locking plate 111 that extends out of the mounting block 3 and is used to drive the portion of the locking plate 111 that extends out of the mounting block 3 to expand radially.

[0069] More specifically, when the ejector pin 121 is forced to move downward, it can drive the locking plate 111 to expand radially (i.e., open), at which time the locking assembly 1 is in the locked state. After the driving force is removed, the ejector pin 121 can move upward under the restoring force of the first return spring 122. After the ejector pin 121 moves, the locking plate 111 can return to its initial position, thereby separating from the mating hole, at which time the locking assembly 1 is in the unlocked state.

[0070] Furthermore, there are multiple locking pieces 111, which are spaced apart in the circumferential direction of the ejector pin 121. The end of the ejector pin 121 is conical, and the shape of all locking pieces 111 matches the shape of the end of the ejector pin 121.

[0071] In this embodiment, there are four locking tabs 111, which are evenly distributed around the circumference of the ejector pin 121. In another embodiment, the number of locking tabs 111 may be two, three, or more.

[0072] Furthermore, the locking part 11 also includes a fourth sealing ring 112, which is fitted onto the area where all locking pieces 111 protrude from the mounting block 3.

[0073] This configuration serves two purposes: firstly, it limits the position of the locking plate 111 and securely fixes it around the ejector pin 121, ensuring that the locking plate 111 adheres tightly to the ejector pin 121 when it opens; secondly, it allows all the locking plates 111 to quickly converge and tighten when they retract, enabling the locking assembly 1 to quickly separate from the product and improving the flexibility of the connector connection mechanism.

[0074] In one specific embodiment, the end of the ejector pin 121 has a limiting boss (not shown), which abuts against the upper surface of the first return spring 122, and the lower surface of the first return spring 122 is limited in the second mounting hole. After the ejector pin 121 passes through the first return spring 122 and extends out of the mounting block 3, it can abut against the locking piece 111.

[0075] At this time, the ejector pin 121 can move downward under the action of external force and drive the locking plate 111 to expand. After the external force is removed, the first return spring 122 can drive the ejector pin 121 to retract through the limiting boss, and after the ejector pin 121 retracts, the locking plate 111 can return to the initial position.

[0076] In other examples, the ejector pin 121 may also be fixed to the lower surface of the first return spring 122, and the ejector pin 121 may stretch the first return spring 122 and move downward under the action of an external force. After the external force is removed, the first return spring 122 may drive the ejector pin 121 to retract under the action of an elastic force.

[0077] Continue to refer to Figure 4 The drive unit 12 also includes a locking sleeve 123, which is fixed in the second mounting hole. The locking sleeve 123 has a first limiting surface (not labeled), and the bottom of the first return spring 122 abuts against the first limiting surface. The first limiting surface is used to limit the axial position of the first return spring 122.

[0078] Further preferably, the drive unit 12 also includes a threaded locking rod 124 and a pin retaining sleeve 125. The locking sleeve 123 has a first receiving cavity (not labeled), and part of the locking rod 124 and the pin retaining sleeve 125 are placed in the first receiving cavity. The locking rod 124 abuts against the pin 121, and the pin retaining sleeve 125 has a cavity. The locking rod 124 and the pin 121 are embedded in the cavity so that the locking rod 124, the pin 121 and the pin retaining sleeve 125 move or rotate together. At this time, the axes of the locking rod 124, the pin 121 and the pin retaining sleeve 125 are all coincident, and the pin retaining sleeve 125 abuts against the top of the first return spring 122.

[0079] When the locking assembly 1 needs to be connected to the product, the operator can rotate or press the locking rod 124. After the locking rod 124 is subjected to force, it drives the ejector pin fixing sleeve 125 and the ejector pin 121 to rotate or move synchronously. When the ejector pin fixing sleeve 125 rotates or moves, it compresses the first return spring 122.

[0080] When the locking assembly 1 needs to be separated from the product, the external force is removed, and the first return spring 122 restores its shape under the action of elastic force, and drives the ejector pin fixing sleeve 125, ejector pin 121 and locking rod 124 to move upward, so as to realize the reset of ejector pin 121.

[0081] Reference Figure 1 and Figure 2 As a non-limiting embodiment, the drive unit 12 also includes a limiting screw 126, and a limiting hole 1231 is provided on the locking sleeve 123. The limiting screw 126 passes through the limiting hole 1231 and is connected to the locking rod 124. The limiting screw 126 can rotate or move in the limiting hole 1231 under the drive of the locking rod 124.

[0082] Preferably, the two ends of the limiting hole 1231 are provided with slots 1232. When the limiting screw 126 moves to the limit position, it can be locked in the slot 1232. With this configuration, the limiting screw 126 can always be locked in the slot 1232 after the external force is removed, thereby fixing the position of the ejector pin 121 and preventing the locking rod 124 from moving. At this time, the ejector pin 121 can always expand the outer diameter of the locking piece 111, thereby keeping the locking piece 111 always fixed in the mating hole of the product, and the product can start the sealing test.

[0083] When it is necessary to separate the locking assembly 1 from the product, the limiting screw 126 can be moved out of the slot 1232 by external force, and then the ejector pin 121 can return to the initial position (i.e., the position before force is applied) under the action of the first return spring 122. During this process, the locking plate 111 can be quickly tightened under the action of the fourth sealing ring 112, so that the locking assembly 1 can be quickly separated from the mating hole of the product. Then, the entire sealing assembly 2 and the locking assembly 1 can be pulled out to complete the sealing test of the product.

[0084] Reference Figure 1 and Figure 2 As shown, in one specific embodiment, the limiting hole 1231 is arc-shaped, and the locking rod 124 can drive the limiting set screw 126 to rotate within the limiting hole 1231. The slots 1232 are provided at both ends of the limiting hole 1231. When it is necessary to separate the locking assembly 1 from the product, the operator can press down on the locking rod 124 to disengage the limiting set screw 126 from the slot 1232. Then, the first return spring 122 can drive the ejector pin 121 and the locking rod 124 to rotate upwards until the ejector pin 121 returns to its initial position.

[0085] In another specific embodiment, the limiting hole 1231 can also be elongated and extend vertically, allowing the locking rod 124 to move the limiting screw 126 within the limiting hole 1231. Slots 1232 are provided at both ends of the limiting hole 1231. When it is necessary to separate the locking assembly 1 from the product, the operator can pull the locking rod 124 upwards to disengage the limiting screw 126 from the slots 1232. Then, the first return spring 122 can move the ejector pin 121 and the locking rod 124 upwards until the ejector pin 121 returns to its initial position.

[0086] Continue to refer to Figure 4 In a preferred embodiment, the locking part 11 further includes a fixing block 113, which is disposed in the second mounting hole and is used to define the position of all locking pieces 111. That is, the locking pieces 111 can be fixed on the fixing block 113 and fixed in the second mounting hole by the fixing block 113.

[0087] Continue to refer to Figure 4 In a preferred embodiment of this utility model, the locking part 11 further includes a second return spring 114, which is fixed in the second mounting hole. The second return spring 114 and the locking piece 111 are respectively disposed on both sides of the fixing block 113. The second mounting hole has a second limiting surface (not labeled). The fixing block 113 is used to make all the locking pieces 111 abut against the second limiting surface under the drive of the second return spring 114, thereby preventing the locking pieces 111 from falling out of the second mounting hole.

[0088] In one embodiment, the locking piece 111 has a radially protruding protruding end 1112. The fixing block 113 is inserted into the protruding end 1112. The second return spring 114, the fixing block 113, and the locking piece 111 are arranged sequentially from top to bottom. The bottom of the protruding end 1112 abuts against the second limiting surface. The second return spring 114 can apply downward pressure to the fixing block 113 to ensure that the protruding end 1112 is always in contact with the second limiting surface.

[0089] Optionally, the locking part 11 may also include a locking plate retaining sleeve 115, which is fixed in the second mounting hole and has a second limiting surface.

[0090] In one example, the locking plate retaining sleeve 115 is preferably connected to the locking sleeve 113 by threads, thereby fixing the locking sleeve 113 in the second mounting hole. Of course, in other examples, the locking plate retaining sleeve 115 may not be connected to the locking sleeve 113, in which case the locking sleeve 113 can be directly fixed in the second mounting hole.

[0091] Further optional, see Figure 4The locking sleeve 113 also has a third limiting surface, and the upper end of the second return spring 114 abuts against the third limiting surface, thereby limiting the position of the top of the second return spring 114. At this time, the locking plate fixing sleeve 115 and the locking sleeve 123 form a second receiving cavity, and the second return spring 114, the fixing block 113 and part of the locking plate 111 can be limited within the second receiving cavity.

[0092] In other embodiments, a third limiting surface may be provided by a locking plate retaining sleeve 115, or a mounting component may be provided in the second mounting hole and a third limiting surface may be provided by the mounting component.

[0093] like Figure 4 As shown, in a preferred example, a fifth sealing ring 116 is provided between the locking plate fixing sleeve 115 and the hole wall of the second mounting hole. The fifth sealing ring 116 can provide damping force when the locking rod 114 rotates to prevent the locking plate fixing sleeve 115 and the locking sleeve 11 from moving under the drive of the locking rod 114.

[0094] Preferably, the end of the locking plate retaining sleeve 115 that extends out of the end of the mounting block 3 is provided with a third thread. After the locking component 1 extends into the second mounting hole, it is engaged with the third thread by the nut 13, thereby fixing the locking component 1 on the mounting block 3.

[0095] A further preferred embodiment may provide a sixth sealing ring 117 between the locking plate retaining sleeve 115 and the nut 13 to seal the gap between the mounting block 3 and the locking plate retaining sleeve 115. The fifth sealing ring 116 and the sixth sealing ring 117 cooperate to keep the locking assembly 1 floating within the mounting block 3, thereby sealing the gap formed after the locking assembly 1 and the mounting block 3 are installed.

[0096] In a non-limiting embodiment, the process of using the connector connection mechanism includes:

[0097] Locking process: After quickly assembling the connector connection mechanism onto the product, press down on the locking rod 124. The limiting screw 126 on the locking rod 124 will rotate along the limiting hole 1231 on the locking sleeve 123. The downward movement of the locking rod 124 will drive the pin fixing sleeve 125 and the pin 121 to move downward and compress the first return spring 114. When the pin 121 moves downward, its head has a conical structure that opens the four locking pieces 111, so that the first thread 1111 on the locking piece 111 engages with the second thread on the product mating hole. This continues until the limiting screw 126 rotates to the lowest point along the limiting hole 1231 on the locking sleeve 123. The limiting screw 126 then enters the slot 1232, and the locking rod 124 can no longer move. The entire connector connection mechanism is fixed on the product, and the sealing test begins.

[0098] Release process: Press the locking rod 124 down, and after the limiting screw 126 disengages from the slot 1232, the locking rod 124 moves upward under the elastic force of the first return spring 114. The limiting screw 126 rotates upward along the limiting hole 1231. The locking rod 124 drives the pin fixing sleeve 125 and the pin 121 to move upward. After the pin 121 moves upward, the four locking pieces 111 tighten quickly under the action of the fourth sealing ring 112. The first thread 1111 on the locking piece 11 quickly separates from the second thread in the product mating hole. Pull the entire connector connection mechanism out of the product to complete the sealing test.

[0099] In summary, this utility model provides a connector connection mechanism that can be connected to the product through the locking component 1, enabling quick locking and unlocking without the need for tools. This facilitates operation, saves time and effort, greatly reduces the labor intensity of employees, and significantly improves production efficiency.

[0100] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the present utility model.
