Description

Technical Field

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

[0002] After the male connector is inserted into the female connector, the male connector needs to be fixed to prevent it from moving along its axial direction.

[0003] Existing structures for fixing male connectors, such as the connector disclosed in CN101036019A, have two locking arms, each with a retaining arm connected to the side of the locking arm closest to the female connector's insertion interface. The locking arms slide tangentially within a channel on the female connector housing, and each locking arm has a locking arm socket formed on the side facing each other (i.e., the inner side of the locking arms). The locking arm socket is formed by the interval between two protrusions distributed vertically. The female connector housing has a locking protrusion that abuts against the upper part of the lower protrusion to restrict the movement of the locking arm tangentially along the female connector, while the upper protrusion is located inside the female connector.

[0004] When the male connector is inserted into the female connector through the female connector's socket, the flange on the male connector presses against the upper protrusion of the locking arm, causing the locking arm to deform axially along the female connector. This causes the lower protrusion on the locking arm to separate from the locking protrusion, allowing the cover of the connector to be pressed down. This causes the locking arm to move the retaining arm connected to one side of it tangentially along the female connector. At this point, the retaining arm moves into the female connector housing and abuts against the side of the male connector's flange near the female connector's socket, axially confining the male connector within the female connector. Simultaneously, the upper protrusion on the inner side of the locking arm separates from the flange on the male connector as the locking arm moves downward. The locking arm then returns to its original shape, causing the locking arm socket to move and engage with the locking protrusion on the female connector, thus restricting the connector's tangential movement along the female connector and securing the male connector inside the female connector.

[0005] However, the locking arm socket is formed by two protrusions distributed vertically on the inner side of the locking arm, which makes its structure relatively complex, resulting in a more complex manufacturing process for the connector. Utility Model Content

[0006] The purpose of this utility model is to provide a connector connection structure and connector assembly to alleviate the technical problem in the prior art where the locking arm socket of the connector used to restrict the axial movement of the male connector within the female connector is formed by two protrusions distributed vertically on the inner side of the locking arm, resulting in a complex locking arm socket structure and a relatively complex manufacturing process for the connector.

[0007] In a first aspect, this utility model provides a connector connection structure, including a locking element and a positioning element; The positioning element is spaced apart on one side of the locking element and connected to the locking element. The projection of the positioning element on the locking element is located between the two ends of the locking element, so that the locking element has a locking part located outside the projection of the positioning element. The locking member and the positioning member are slidably connected to the sliding hole on the female connector housing along the tangential direction of the female connector. The locking part has an abutting protrusion on the side facing the central axis of the female connector. The abutting protrusion is located inside the female connector when the positioning member is not slid into the female connector, and is pushed by the male connector when the male connector is inserted into the female connector, moving away from the positioning member along the axial direction of the female connector. A locking protrusion extending axially along the female connector is formed on the side of the locking part near the positioning member. The locking protrusion is used to engage with a first groove in the inner wall of the sliding hole when the abutment protrusion is located inside the female connector, and to engage with a second groove in the inner wall of the sliding hole when the positioning member slides into the female connector. The second groove is located on the side of the first groove away from the central axis of the female connector housing.

[0008] In an optional embodiment, the portion of the locking part that covers the projection of the positioning member is a fixing part, one end of the locking part is connected to the fixing part, and the locking part and the fixing part are inclined relative to each other. The locking portion is inclined from the end near the fixing portion to the end away from the fixing portion in the direction close to the positioning member.

[0009] In an optional embodiment, a bend is provided between the two ends of the locking part, the bend being used to bend the locking part from the bend to its end away from the fixing part in a direction away from the positioning member.

[0010] In an optional embodiment, the side of the locking portion opposite to the positioning member forms an obtuse angle at the bend.

[0011] In an optional embodiment, the abutment protrusion is located at the bend.

[0012] In an alternative embodiment, the locking protrusion is located on the side of the bend away from the fixing portion.

[0013] In an optional embodiment, the locking protrusion is located at the end of the locking portion away from the fixing portion.

[0014] In an alternative embodiment, the locking protrusion bends toward the positioning member to form a hook.

[0015] In an optional embodiment, a pressing member is also included, wherein the locking member and the positioning member are fixedly connected by the pressing member.

[0016] Secondly, this utility model provides a connector assembly, including the connector connection structure described in any of the foregoing embodiments.

[0017] The connector connection structure provided by this utility model includes a locking member and a positioning member; the positioning member is spaced apart on one side of the locking member and connected to the locking member, and the projection of the positioning member on the locking member is located between the two ends of the locking member, so that the locking member has a locking part located outside the projection of the positioning member; the locking member and the positioning member are used to slide tangentially in the sliding hole on the female connector housing along the female connector, and the side of the locking member facing the central axis of the female connector is provided with an abutting protrusion, which is used to be located inside the female connector when the positioning member is not slid into the female connector, and to be pushed by the male connector and moved away from the positioning member along the axial direction of the female connector when the male connector is inserted into the female connector; a locking protrusion extending along the axial direction of the female connector is formed on the side of the locking member near the positioning member, and the locking protrusion is used to engage in the first groove of the inner wall of the sliding hole when the abutting protrusion is located inside the female connector, and to engage in the second groove of the inner wall of the sliding hole when the positioning member slides into the female connector, the second groove being located on the side of the first groove away from the central axis of the female connector housing. The connector connection structure provided by this utility model is used for the insertion and fixing between female connectors and male connectors. The female connector housing includes an insertion end for inserting the male connector. Before inserting the male connector into the female connector, the locking member and the positioning member need to be slidably installed in the sliding hole of the female connector housing along the tangent of the female connector, so that the positioning member is located between the locking member and the insertion end of the female connector housing. At the same time, the locking protrusion on the locking part needs to be engaged with the first groove on the sliding hole of the female connector housing to support the locking member and the positioning member, so that the abutting protrusion on the locking part is located inside the female connector and the positioning member is prevented from extending into the female connector housing. When the male connector is inserted into the female connector, the flange on the male connector first passes the positioning element and then abuts against the abutment protrusion, pushing the abutment protrusion and causing the locking part to move away from the positioning element. This causes the locking protrusion on the locking part to retract from the first groove, unlocking the locking element from the female connector housing. At this point, the locking element and positioning element can be pushed radially along the female connector housing, causing the positioning element to extend into the female connector housing and abut against the side of the male connector flange near the insertion end of the female connector housing. This positioning element confines the male connector within the female connector housing, preventing it from retracting. As the positioning element extends into the female connector housing, the locking element moves synchronously, causing the abutment protrusion on it to move out of the female connector housing and the locking protrusion to move towards the second groove until the locking protrusion engages in the second groove. Once the locking protrusion is engaged in the second groove, the locking element re-locks with the female connector housing. At this point, the locking element limits the position of the positioning element, ensuring the positioning element's limiting effect on the male connector.As can be seen, the connector connection structure provided by this utility model achieves locking between the locking member and the female connector housing by engaging a locking protrusion located on the locking part near the positioning member and extending along the axial direction of the female connector with the first or second groove on the female connector housing. This achieves the fixing effect of the positioning member on the male connector inside the female connector. Compared with the two protrusions distributed vertically on the inner side of the existing locking arm, this effectively simplifies the structure of the locking member and reduces the manufacturing process of the locking member. In addition, it should be noted that the two protrusions distributed vertically on the inner side of the existing locking arm engage with the locking protrusion on the female connector housing to achieve the locking process between them. However, compared with forming a protrusion on the female connector, forming a groove on the female connector is simpler and has lower requirements for processing technology. Therefore, although the connector connection structure provided by this utility model needs to be used in conjunction with the female connector housing with the first and second grooves, it does not increase the processing difficulty of the female connector. On the contrary, it reduces the processing difficulty of the female connector, thereby effectively improving the processing convenience of the female connector.

[0018] Compared with the prior art, the connector connection structure provided by this utility model forms a locking protrusion extending along the axial direction of the female connector on the side of the locking part near the positioning member, and then uses the locking protrusion to engage with the first groove or the second groove on the female connector shell. This can reduce the number of protrusions on the locking member while locking the locking member to the female connector shell, thereby simplifying the structure of the locking member and improving its processing convenience.

[0019] The connector assembly provided by this utility model includes the above-mentioned connector connection structure, and therefore the connector assembly has the same beneficial effects as the above-mentioned connector connection structure. Attached Figure Description

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0024] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0025] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0026] Example: like Figure 1 As shown, the connector connection structure provided in this embodiment includes a locking member 1 and a positioning member 2; the positioning member 2 is spaced apart on one side of the locking member 1 and connected to the locking member 1, and the projection of the positioning member 2 on the locking member 1 is located between the two ends of the locking member 1, so that the locking member 1 has a locking portion 10 located outside the projection of the positioning member 2; as shown Figure 2 and Figure 3As shown, locking member 1 and positioning member 2 are slidably connected to the sliding hole 30 on the outer shell of female connector 3 along the tangential direction of female connector 3. Abutment protrusion 100 is provided on the side of locking part 10 facing the central axis of female connector 3. The abutment protrusion 100 is located inside female connector 3 when positioning member 2 is not slid into female connector 3, and is pushed by male connector 4 when male connector 4 is inserted into female connector 3, moving away from positioning member 2 along the axial direction of female connector 3. A locking protrusion 101 extending axially along female connector 3 is formed on the side of locking part 10 near positioning member 2. The locking protrusion 101 is engaged in the first groove 300 on the inner wall of sliding hole 30 when abutment protrusion 100 is located inside female connector 3, and in the second groove 301 on the inner wall of sliding hole 30 when positioning member 2 slides into female connector 3. Figure 2 As shown, the second groove 301 is located on the side of the first groove 300 away from the central axis of the female connector 3 housing.

[0027] The connector connection structure provided in this embodiment is applied to... Figure 2 The female connector 3 shown is Figure 4 The male connector 4 is shown to be fixed in place by insertion. The female connector 3 housing includes an insertion end 31 for inserting the male connector 4. Before inserting the male connector 4 into the female connector 3, it is necessary to... Figure 3 As shown, locking member 1 and positioning member 2 are slidably installed along the tangential direction of female connector 3 into the sliding hole 30 of the female connector 3 housing, such that positioning member 2 is located between locking member 1 and the insertion end 31 of female connector 3 housing. Meanwhile, as... Figure 5 As shown, the locking protrusion 101 on the locking part 10 also needs to engage with the first groove 300 on the sliding hole 30 of the female connector 3 housing to support the locking member 1 and the positioning member 2, thereby achieving the desired effect. Figure 3 As shown, the abutment protrusion 100 on the locking part 10 is located inside the female connector 3 and the positioning member 2 is prevented from extending into the housing of the female connector 3.

[0028] To achieve the installation and fixation of the male connector 4 within the female connector 3, such as Figure 4 As shown, a flange 40 is typically provided between the two ends of the male connector 4. When the male connector 4 is inserted into the female connector 3, as... Figure 6As shown, the flange 40 on the male connector 4 will first pass through the side of the positioning member 2 and then abut against the abutment protrusion 100 and push the abutment protrusion 100 to drive the locking part 10 to move away from the positioning member 2. Then, the locking protrusion 101 on the locking part 10 will be driven to exit from the first groove 300, so that the locking member 1 and the female connector 3 housing are unlocked. At this time, the locking member 1 and the positioning member 2 can be pushed radially along the female connector 3 housing, so that the positioning member 2 extends into the female connector 3 housing and abuts against the side of the male connector 4 flange 40 near the female connector 3 housing insertion end 31. Thus, the positioning member 2 is used to limit the male connector 4 to be inside the female connector 3 housing, preventing the male connector 4 from exiting the male connector 4 housing. When the positioning member 2 extends into the housing of the female connector 3, the locking member 1 also moves synchronously with the positioning member 2, thereby causing the abutment protrusion 100 on it to move out of the housing of the female connector 3 and causing the locking protrusion 101 on it to move toward the second groove 301 until the locking protrusion 101 is engaged in the second groove 301. After the locking protrusion 101 is engaged in the second groove 301, the locking member 1 is re-locked to the housing of the female connector 3. At this time, the locking member 1 can limit the position of the positioning member 2, thereby ensuring the limiting effect of the positioning member 2 on the male connector 4.

[0029] As can be seen, the connector connection structure provided in this embodiment can achieve locking between the locking member 1 and the shell of the female connector 3 by cooperating with the locking protrusion 101 provided on the side of the locking part 10 near the positioning member 2 and extending along the axial direction of the female connector 3 and the first groove 300 or the second groove 301 on the shell of the female connector 3. This achieves the fixing effect of the positioning member 2 on the male connector 4 inside the female connector 3. Compared with the two protrusions distributed vertically on the inner side of the existing locking arm, the structure of the locking member 1 can be effectively simplified, thereby reducing the manufacturing process of the locking member 1.

[0030] Furthermore, it should be noted that the two protrusions distributed vertically on the inner side of the existing locking arm cooperate with the locking protrusions on the female connector 3 housing to achieve the locking process between them and the housing. However, compared to forming protrusions on the female connector 3, forming grooves on the female connector 3 is a simpler process and has lower requirements for processing technology. Therefore, although the connector connection structure provided in this embodiment needs to be used in conjunction with the female connector 3 housing with the first groove 300 and the second groove 301, it will not lead to an increase in the processing difficulty of the female connector 3. On the contrary, it will reduce the processing difficulty of the female connector 3, thereby effectively improving the processing convenience of the female connector 3.

[0031] Compared with the prior art, the connector connection structure provided in this embodiment forms a locking protrusion 101 extending axially along the female connector 3 on the side of the locking part 10 near the positioning member 2, and then uses the locking protrusion 101 to engage with the first groove 300 or the second groove 301 on the outer shell of the female connector 3. This can reduce the number of protrusions on the locking member 1 while locking the locking member 1 and the outer shell of the female connector 3, thereby simplifying the structure of the locking member 1 and improving its processing convenience.

[0032] like Figure 1 As shown, the portion of the locking part 10 that covers the projection of the positioning member 2 is the fixing part 11. One end of the locking part 10 is connected to the fixing part 11, and the locking part 10 and the fixing part 11 are inclined relative to each other. The locking part 10 is inclined in the direction close to the positioning member 2 from the end of it that is close to the fixing part 11 to the end that is far away from the fixing part 11.

[0033] This configuration allows the locking part 10 to deform toward the positioning member 2, making it easy for the locking part 10 to deform when the abutting protrusion 100 is pushed and moved by the male connector 4, thereby causing the locking protrusion 101 to exit from the first groove 300. It also makes it easy for the locking part 10 to return to its original shape when the abutting protrusion 100 exits from the outer shell of the female connector 3, thereby causing the locking protrusion 101 to enter the second groove 301, thus effectively improving the performance of the locking member 1.

[0034] Furthermore, such as Figure 1 As shown, a bend 102 is provided between the two ends of the locking part 10. The bend 102 is used to bend the locking part 10 from the bend 102 to its end away from the fixing part 11 in a direction away from the positioning member 2.

[0035] When the locking part 10 is deformed by the male connector 4 pushing against the protrusion 100, the bending part 102 can reduce the deformation deflection of the locking part 10, thereby preventing the locking part 10 from breaking due to excessive deformation.

[0036] like Figure 1 As shown, the side of the locking part 10 facing away from the positioning member 2 forms an obtuse angle at the bend 102.

[0037] Compared to right angles or acute angles, obtuse angles can further reduce the deformation deflection of the locking part 10 when it deforms, thereby effectively ensuring the performance of the locking part 10.

[0038] To improve the smoothness of the movement of the locking part 10 driven by the abutment protrusion 100, such as Figure 1 As shown, the abutment protrusion 100 is located at the bend 102.

[0039] To improve the smoothness of the locking part 10 driving the locking protrusion 101 in and out of the first groove 300 or the second groove 301, such as Figure 1As shown, the locking protrusion 101 can be located on the side of the bend 102 away from the fixing part 11.

[0040] Furthermore, the locking protrusion 101 is located at the end of the locking portion 10 away from the fixing portion 11. This arrangement increases the distance between the abutment protrusion 100 and the locking protrusion 101, so that the locking protrusion 101 can be moved in and out of the first groove 300 or the second groove 301 with a shorter movement of the abutment protrusion 100.

[0041] To improve the engagement stability between the first groove 300 or the second groove 301 and the locking protrusion 101, such as Figure 1 As shown, the locking protrusion 101 can be bent toward the positioning member 2 to form a hook.

[0042] like Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, the connector connection structure provided in this embodiment also includes a pressing member 5, and the locking member 1 and the positioning member 2 are fixedly connected by the pressing member 5.

[0043] The pressing component 5 not only supports the locking component 1 and the positioning component 2 to be spaced apart and improves the connection stability between the locking component 1 and the positioning component 2, but also provides a larger area of ​​force application for the process of manually pushing the locking component 1 and the positioning component 2, thereby improving the ease of use of the connector connection structure.

[0044] It should be noted that when it is necessary to pull the male connector 4 out of the female connector 3, the locking protrusion 101 can be manually removed from the second groove 301, and then the pressing member 5 can be manually pulled out of the female connector 3, thereby pulling the locking member 1 and the positioning member 2 outward along the radial direction of the female connector 3, releasing the locking member 2 on the male connector 4 and allowing the locking protrusion 101 to re-enter the first groove 300.

[0045] To improve the ease of removing the pressing component 5, such as Figure 1 As shown, one side of the pressing member 5 may be provided with an extension that extends axially along the female connector 3.

[0046] This embodiment also provides a connector assembly, which includes the aforementioned connector connection structure. The connector assembly may also include the aforementioned female connector 3 housing and a male connector 4 with a flange 40. Since the connector assembly includes the aforementioned connector connection structure, the connector assembly and the aforementioned connector connection structure can solve the same technical problem and achieve the same technical effect, which will not be described in detail here.

[0047] 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.
