Description

Technical Field

[0001] This utility model relates to the field of quick-release connector technology, and in particular to a connector structure, plug structure and plug assembly with feedback on insertion and removal status. Background Technology

[0002] With the rapid development of the automotive industry, plastic quick-connect fittings are being used more and more widely in water, air, oil and battery cooling systems.

[0003] With the diversification of vehicle models and the increasing number of application scenarios, the corresponding functional requirements for plastic quick-connect fittings are also becoming more diverse. Previously, fittings in piping systems generally didn't require many insertions and removals; once inserted, they were usually not pulled out again. Therefore, it was sufficient to ensure that all fittings clicked when inserted during piping system installation. However, as major vehicle manufacturers have increasingly stringent requirements, and with the growing prevalence of quick-connect fittings with shut-off functions (which allow for immediate insertion and removal without draining fluid during piping maintenance), fittings now need to provide feedback on their connection status.

[0004] Therefore, how to enable quick-connect connectors to have the function of feedback on their own connection status and improve the safety of the connectors has become an urgent technical challenge that the industry needs to overcome. Utility Model Content

[0005] The purpose of this invention is to provide a connector structure, plug structure, and plug assembly with feedback on the insertion and removal status, so as to alleviate the technical problem that quick-connect connectors in the prior art do not have the function of feedback on their own insertion and removal status.

[0006] In a first aspect, the connector structure with a feedback insertion / removal state provided by this utility model is used to connect with a plug structure, including: a connector body, a spring body, and an elastic member.

[0007] The connector body is provided with a spring slot, the elastic member is disposed in the spring slot, one end of the spring body extends into the spring slot and is connected to the elastic member, and the elastic member is used to give the spring body a tendency to move in the direction of extending out of the spring slot;

[0008] The spring body is configured to be pushed by the plug structure and move toward extending into the spring slot.

[0009] In an optional implementation,

[0010] The main body of the spring is equipped with a scanning code;

[0011] The outer wall of the connector body has a notch forming a window;

[0012] When the plug structure is inserted into the connector body and connected to it, the scan code is located at the position of the window.

[0013] In an optional implementation,

[0014] When the plug structure is not connected to the connector body, the scanning code is blocked by the outer wall of the connector body.

[0015] In an optional implementation,

[0016] The inner wall of the spring slot extends inward and is provided with an abutment protrusion; the side wall of the spring body extends outward and is provided with a limiting buckle; the abutment protrusion can abut against the limiting buckle to prevent the spring body from coming out of the spring slot.

[0017] In an optional implementation,

[0018] The side wall of the spring slot has a notch, and the plug structure can extend into the spring slot through the notch so that the plug structure can push the spring body.

[0019] In an optional implementation,

[0020] The connector body has an inner cavity for inserting the plug structure, and the inner cavity communicates with the spring slot through the notch.

[0021] In an optional implementation,

[0022] The connector body is provided with a retaining spring for connecting the plug structure.

[0023] In an optional implementation,

[0024] One end face of the spring sheet body has a mounting positioning post, and the elastic member is sleeved on the mounting positioning post.

[0025] Secondly, the plug structure provided by this utility model is used to connect with the connector structure having a feedback plug-in / plug-out state.

[0026] The plug structure is provided with a protrusion for pushing the spring body.

[0027] Thirdly, the plug-in assembly provided by this utility model includes the connector structure having a feedback plug-in / plug-out state and the plug structure.

[0028] The connector structure with feedback on insertion / removal status provided by this utility model has a spring slot on the connector body, and an elastic member is set in the spring slot. Since one end of the spring body extends into the spring slot and connects with the elastic member, the elastic force generated by the elastic member acts on the spring body. When the plug structure is inserted into the connector structure, the plug structure pushes the spring body to move in the direction of extending into the spring slot. Thus, the insertion position of the plug structure is determined by the position of the spring body, realizing the function of feedback on insertion status of the connector structure, improving the safety of the plug, and alleviating the technical problem that quick-connect connectors in the prior art do not have the function of feedback on their own insertion status.

[0042] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0043] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0044] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0045] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0046] like Figure 1 , Figure 2 As shown, existing quick-connect connectors all have retaining rings 140 or clamps to secure the connector. Usually, the "click" sound when the retaining ring 140 clicks into the slot of the connector is used to determine whether the connector is inserted properly. Once inserted, it is difficult to determine whether the current state is properly inserted. If it is not inserted properly, there is a risk of leakage.

[0047] In view of this, such as Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the connector structure with feedback insertion and removal status provided in this embodiment is used to connect with the plug structure 400, and includes: connector body 100, spring body 200 and elastic member 300.

[0048] The connector body 100 has a cylindrical structure. A spring slot 110 is provided on the side wall of the connector body 100. An elastic member 300 is disposed in the spring slot 110. The elastic member 300 is specifically configured as a compression spring. One end of the spring body 200 extends into the spring slot 110 and is connected to the elastic member 300. The elastic member 300 is elastic and is used to make the spring body 200 have a tendency to move in the direction of extending out of the spring slot 110.

[0049] The spring body 200 is configured to be pushed by the plug structure 400 and move toward the direction of extending into the spring slot 110. Since the spring body 200 and the plug structure 400 move together, the insertion position of the plug structure 400 can be fed back by measuring the position of the spring body 200.

[0050] Furthermore, such as Figure 8 As shown, the spring body 200 is equipped with a scanning code 210, which moves together with the spring body 200, such as... Figure 9 As shown, the outer wall of the connector body 100 has a notch forming a window 120; when the plug structure 400 is inserted into the connector body 100 and connected to each other, the scanning code 210 is located in the window 120, the scanning code 210 is exposed and can be identified and scanned, thereby feeding back the position information of the spring body 200, and then feeding back the insertion of the plug structure 400 into place, which is the insertion state.

[0051] The scanning code 210 can be set to various forms, such as barcodes, QR codes, etc. Different types of scanning codes 210 can be selected according to actual needs. Preferably, the scanning code 210 is a QR code.

[0052] In an optional implementation, when the plug structure 400 is not connected to the connector body 100, the scanning code 210 is blocked by the outer wall of the connector body 100, and the scanning code 210 cannot be scanned and identified, indicating that the connector structure has not been inserted into place, and is in the unplugged state.

[0053] In alternative implementations, such as Figure 10 As shown, the inner wall of the spring slot 110 extends inward and is provided with abutment protrusions 111. There are two abutment protrusions 111, which are arranged opposite to each other. The side wall of the spring body 200 extends outward and is provided with limit buckles 220. There are two limit buckles 220, which are located on both sides of the spring body 200. The abutment protrusions 111 can abut against the limit buckles 220 to prevent the spring body 200 from coming out of the spring slot 110.

[0054] like Figure 4 , Figure 5 As shown, when the plug structure 400 is not inserted into the connector structure, the spring body 200 is not connected to the plug structure 400. The elastic force generated by the elastic member 300 moves the spring body 200 toward the direction of extending out of the spring slot 110. Since the abutting boss 111 and the limiting buckle 220 abut against each other, they can prevent the spring body 200 from coming out of the spring slot 110 and restrict the spring body 200 in the spring slot 110.

[0055] In an optional embodiment, the sidewall of the spring slot 110 has a notch 112, through which the plug structure 400 can extend into the spring slot 110 so that the plug structure 400 can push the spring body 200.

[0056] In order to push the spring body 200, a protrusion 410 is provided on the outer wall of the plug structure 400. The protrusion 410 can pass through the notch 112 and extend into the spring slot 110, so that the protrusion 410 abuts against the spring body 200. When the plug structure 400 is inserted into the connector structure, the protrusion 410 pushes the spring body 200, thereby realizing that the plug structure 400 and the spring body 200 move together.

[0057] In an optional embodiment, the connector body 100 has an inner cavity 130 for inserting the plug structure 400. The inner cavity 130 is located in the middle of the connector body 100 and communicates with the spring slot 110 through a notch 112. When the plug structure 400 is inserted into the inner cavity 130, the protrusion 410 on the plug structure 400 extends into the spring slot 110 through the notch 112. The protrusion 410 abuts against the spring body 200 and pushes the spring body 200 to move together with the plug structure 400.

[0058] In an optional embodiment, the connector body 100 is provided with a retaining ring 140 for connecting the plug structure 400. The use of the retaining ring 140 is prior art, and the specific structure and installation method of the retaining ring 140 will not be described in detail here.

[0059] In an optional embodiment, one end face of the spring body 200 has a mounting positioning post 230, and the elastic member 300 is sleeved on the mounting positioning post 230. The mounting positioning post 230 serves to position the elastic member 300. During installation, the elastic member 300 can be directly sleeved on the mounting positioning post 230. In addition, the mounting positioning post 230 can also prevent the elastic member 300 from shaking.

[0060] The connector structure with feedback insertion / removal status provided in this embodiment has a spring slot 110 on the connector body 100, and an elastic member 300 is disposed in the spring slot 110. Since one end of the spring body 200 extends into the spring slot 110 and is connected to the elastic member 300, the elastic force generated by the elastic member 300 acts on the spring body 200. When the plug structure 400 is inserted into the connector structure, the plug structure 400 pushes the spring body 200 to move in the direction of extending into the spring slot 110. Thus, the insertion position of the plug structure 400 is determined by the position of the spring body 200, thereby enabling the connector structure to have the function of feedback insertion status, improving the safety of the plug, and alleviating the technical problem that quick-connect connectors in the prior art do not have the function of feedback of their own insertion status.

[0061] Based on the above embodiments, such as Figure 11 As shown, the plug structure 400 provided in this embodiment is used to connect with a connector structure that has a feedback plugging / unplugging state; the plug structure 400 is provided with a protrusion 410 for pushing the spring body 200.

[0062] Specifically, the plug structure 400 is adapted to the connector structure with feedback insertion / removal status provided in the above embodiment. In order to enable the spring body 200 to be pushed, the plug structure 400 is provided with a protrusion 410. The protrusion 410 extends through the notch 112 into the spring slot 110. The protrusion 410 pushes the spring body 200. When the plug structure 400 is inserted into place, the scanning code 210 on the spring body 200 is located at the window 120 and the scanning code 210 is exposed, thereby providing feedback that the plug structure 400 is inserted into place. When the plug structure 400 is in the removed state, the scanning code 210 on the spring body 200 is blocked and the scanning code 210 cannot be recognized, thereby providing feedback that the plug structure 400 is in the removed state.

[0063] Based on the above embodiments, the plug-in assembly provided in this embodiment includes a connector structure with feedback plugging / unplugging status and a plug structure 400.

[0064] Since the technical effects of the plug-in assembly provided in this embodiment are the same as those of the connector structure with feedback plug-in / plug-out status provided in the above embodiments, they will not be described again here.

[0065] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
