Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a composite connector housing and a split self-locking connector. Background Technology

[0002] For complex housing components, such as the housing structure of a split self-locking connector, the structure needs to accommodate the connection of multiple parts, namely the male and female connectors, and the installation of the drive components, thus requiring a certain level of strength. Simultaneously, the housing component must meet the operational requirements of the drive components to achieve locking and unlocking of the male and female connectors. Correspondingly, the housing component needs to provide functional requirements for components such as latches and buttons, or assembly requirements, all of which contribute to the complexity of the housing component structure. Currently, plastic housing components are mostly produced using integrated machining to ensure structural strength, but this method has a long processing cycle, and complex structures require more advanced machine tools, leading to increased costs. Pure plastic injection molding, on the other hand, results in complex mold structures due to the complex structure of the locking area on the housing component, with wall thicknesses far exceeding other areas. This makes modification and mass production difficult. Furthermore, the injection molding process suffers from significant uneven shrinkage across different wall areas, leading to injection molding defects such as shrinkage, warping, bubbles, and internal stress, thus affecting the yield and service life of the housing component.

[0003] Therefore, how to reduce the production difficulty of complex shell components while meeting their structural strength requirements is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a composite connector housing and a split self-locking connector, so as to reduce the production difficulty of complex housing parts and meet their structural strength requirements.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A composite connector housing, comprising:

[0007] The enclosure area and the load-bearing area, wherein the wall thickness of the enclosure area is a first preset thickness, and the enclosure area constitutes the outer surrounding structure of the composite connector housing;

[0008] The bearing area is located inside the area surrounded by the enclosure area. The hardness of the bearing area is greater than that of the enclosure area. A connecting part is provided on the bearing area in contact with the enclosure area. The bearing area is injection molded and connected to the enclosure area as an insert to form an integral structure. The enclosure area is filled with the connecting part.

[0009] Preferably, in the above-mentioned composite connector housing, the bearing area has a through locking hole, and one side wall of the bearing area has an adjustment groove that communicates with the outer wall of the locking hole; one side wall of the enclosure area has a through hole that is aligned with the axial upward side of the locking hole.

[0010] Preferably, in the above-mentioned composite connector housing, the connecting portion includes at least a first adhesive groove and a second adhesive groove, the lengths of the first adhesive groove and the second adhesive groove are perpendicular, and the enclosure area completely fills the first adhesive groove and the second adhesive groove.

[0011] Preferably, in the above-mentioned composite connector housing, the connecting part further includes a rubber-plastic flange, on which a plurality of connecting holes are spaced apart, the enclosure area passes through the connecting holes, and a limiting protrusion with an outer diameter larger than that between the connecting holes is formed at both ends of the connecting holes in the axial direction.

[0012] Preferably, in the above-mentioned composite connector housing, the first adhesive groove is a dovetail groove structure, or a combination structure of a dovetail groove and a cylindrical hole.

[0013] Preferably, in the above-mentioned composite connector housing, the material of the bearing area is brass, aluminum alloy or stainless steel, and the material of the enclosure area is plastic.

[0014] A split self-locking connector includes a composite connector housing as described in any of the above claims, and further includes a male connector assembly and a female connector assembly. The female connector assembly is fixedly disposed in the bearing area, and the male connector assembly passes through one side wall of the enclosure area and docks with the female connector assembly within the bearing area.

[0015] Preferably, the above-mentioned split self-locking connector further includes a button assembly, which includes a pressing part, a connecting ring, and a return spring. The connecting ring is fixed to one side of the pressing part and embedded in the bearing area, and the bottom of the pressing part abuts against the return spring.

[0016] The outer wall of the male connector is recessed with a insertion groove. The male connector passes through the connecting ring and mates with the female connector. When the male connector is in the mating position, the connecting ring is engaged in the insertion groove to lock the male connector. When the pressing part is subjected to pressure, it drives the connecting ring to leave the insertion groove to unlock the male connector.

[0017] Preferably, the above-mentioned split self-locking connector further includes a button plate, which is fixed to the outer wall of the bearing area. When no external force is applied, the pressing part is stopped and limited by the button plate to a position flush with the outer wall surface of the bearing area under the rebound action of the return spring.

[0018] Preferably, in the above-mentioned split self-locking connector, at least two return springs are provided, and the return springs are evenly distributed circumferentially on the pressing part.

[0019] As can be seen from the above technical solution, the composite connector housing provided by this utility model mainly includes a protective area and a load-bearing area. The protective area forms the outer enclosure structure of the composite connector housing to block and protect against external impurities or collision risks. The load-bearing area is located inside the enclosure area to provide space for the male and female connectors to connect and lock together. Simultaneously, the material hardness of the load-bearing area is greater than that of the enclosure area, ensuring sufficient modal strength and service life when providing connection space. Furthermore, the wall thickness of the protective area is a first preset thickness. Within this first preset thickness, the protective area can be injection molded, improving the processing consistency of its various areas and reducing shrinkage caused by inconsistent shrinkage during injection molding. The design mitigates risks associated with water, warpage, bubbles, and internal stress, while possessing the foundation for mass production mold opening. The load-bearing area serves as an insert structure, independently pre-produced to meet complex structural requirements and the structural strength requirements of thin-walled areas. Simultaneously, as an insert, it is tightly connected to the enclosure area as an integrated structure through insert injection molding. To ensure a tight connection, a connecting portion is provided on the load-bearing area, which is filled during the injection molding process to further fix it to the load-bearing area. The partitioned design and insert injection molding method not only ensures the structural strength of the load-bearing area but also reduces the production difficulty of the enclosure area, balancing the strength and production requirements of the composite connector housing, improving the service life of the composite connector housing, and optimizing production costs.

[0034] The core of this utility model lies in disclosing a composite connector housing and a split self-locking connector, so as to reduce the production difficulty of complex housing parts and meet their structural strength requirements.

[0035] To enable those skilled in the art to better understand the present invention, embodiments of the present invention will be described below with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the invention as described in the claims. Additionally, the complete contents of the configurations shown in the following embodiments are not limited to those necessary for the solution of the invention as described in the claims.

[0036] like Figure 1 , Figure 2 and Figure 3As shown in the figure, the composite connector housing provided in this utility model embodiment is designed and manufactured in a partitioned manner. Its main design consists of an enclosure area 10 and a load-bearing area 20. The wall thickness of the enclosure area 10 is a first preset thickness. It should be noted that in some embodiments of this disclosure, the first preset thickness is 0.6mm-3.8mm. Within the range of the first preset thickness, the enclosure area 10 can provide the necessary structural strength and effectively protect the internal components from the influence of external dust, liquids and other environmental factors. At the same time, the thickness of the enclosure area 10 is relatively uniform. By dividing the required outer wall thickness area of ​​the composite connector housing, the enclosure area 10 is designed, and the enclosure area 10 can be injection molded and maintain a relatively uniform state in each position. By designing the relatively uniform thickness, injection molding defects such as shrinkage, warping, bubbles, and internal stress are reduced.

[0037] The bearing area 20 is located inside the enclosure area 10 and has a higher hardness than the enclosure area 10. This allows the bearing area 20 to withstand greater mechanical stress during the use of the connector. It should be noted that, unlike the protective structure of the enclosure area 10, the bearing area 20 provides space for the connection of the male and female connectors. Therefore, the bearing area 20 needs to have an opening for component insertion and must withstand the impact during insertion and removal operations. Thus, the material hardness of the bearing area 20 is greater than that of the enclosure area 10. In some embodiments of this disclosure, the enclosure area 10 is made of plastic, while the bearing area 20 is made of metal, such as brass, aluminum alloy, or stainless steel, to meet strength requirements. It should also be noted that, compared to the enclosure area 10, the load-bearing area 20 is a more complex structural area in the shell. It needs to meet the locking and adjustment requirements of the male and female heads. Therefore, the load-bearing area 20 is preferably pre-produced independently. By pre-producing the load-bearing area 20, which is made of harder material, the accuracy of its locking area structure is maintained. It can also maintain strength in weaker areas with hard materials, and complete the production of areas with excessive thickness by machining on the outside. This avoids the problems of insufficient structural strength in weak areas and warping and internal stress that are prone to occur in areas with excessive thickness in the production of plastic materials.

[0038] Based on the aforementioned structure, the independently pre-produced carrier area 20 can serve as an insert structure, connecting to the enclosure area 10 as a single unit through injection molding. The relatively simple structure of the enclosure area 10 simplifies the mold structure, reduces the difficulty of injection molding, and achieves mass production. Simultaneously, to ensure a stable connection between the enclosure area 10 and the carrier area 20 during insert injection molding, a connecting portion is provided in the area of ​​the carrier area 20 that contacts the enclosure area 10. The enclosure area 10 fills this connecting portion during injection molding to increase the contact area between the enclosure area 10 and the carrier area 20, or forms a limiting structure after injection molding through the connecting portion, thereby achieving a tight fit between the two. It should be noted that the connection portion and injection molding method not only ensures the strength of the connection but also avoids assembly errors and loosening problems that may arise from traditional screw or snap-fit ​​mechanical connections. This achieves a seamless transition between the carrier area 20 and the enclosure area 10, improving the overall sealing and reliability of the connector housing.

[0039] Based on the above embodiments, such as Figure 2 and Figure 3 As shown, in order to meet the locking connection requirements of the male and female connectors within the bearing area 20, a through locking hole 210 is provided on the bearing area 20 to provide insertion channels from both sides. Correspondingly, an adjustment groove 220 is also provided on one side wall of the bearing area 20, which connects to the outer wall of the locking hole 210. The adjustment groove 220 is used to provide insertion space for the adjustment component, that is, the adjustment component can be inserted from the position of the adjustment groove 220 and reach the position of the locking hole 210. One or both of the male and female connectors can connect within the locking hole 210 and interact with the adjustment component. By setting different adjustment components, the angle of the connection structure of the male and female connectors can be adjusted, or the male and female connectors can be locked in their axial direction, thereby reducing the risk of slippage of the male and female connectors after connection. It should also be noted that a through hole 110 is provided on one side wall of the enclosure 10, which is aligned with the upward side of the locking hole 210, so that when the connector is installed, the male or female head can directly enter the locking hole 210 through the side wall of the enclosure 10, thereby improving the ease of connection.

[0040] Furthermore, the connection stability between the enclosure area 10 and the load-bearing area 20 is fundamental to the effective operation of the connector housing, as demonstrated in some embodiments of this disclosure, such as... Figure 3As shown, the connecting portion provided on the bearing area 20 includes at least a first adhesive-pull groove 230 and a second adhesive-pull groove 240, so that the enclosure area 10 has a larger contact area with the bearing area 20 during injection molding. Simultaneously, the lengths of the first adhesive-pull groove 230 and the second adhesive-pull groove 240 are perpendicular, and the enclosure area 10 completely fills the first adhesive-pull groove 230 and the second adhesive-pull groove 240. During injection molding, the enclosure area 10 is overfilled in the first adhesive-pull groove 230 and the second adhesive-pull groove 240 to form two adhesive-pull connection areas in different directions. This creates support in two directions between the enclosure area 10 and the bearing area 20, ensuring that the composite connector housing has a sufficiently thick adhesive-filled area to resist impact in either direction, thereby improving the structural strength and service life of the composite connector housing.

[0041] It should be noted that the two vertically aligned adhesive grooves not only effectively connect the enclosure area 10 and the load-bearing area 20, but also resist impact forces from different directions, thus enhancing the effectiveness of the integrated structure formed by the enclosure area 10 and the load-bearing area 20. Considering the operating conditions required for the composite connector housing, the shape and size of the adhesive grooves can be adjusted according to actual needs to adapt to different connection structures and usage scenarios. Specifically, by increasing the depth and width of the adhesive grooves, it can be ensured that the plastic material can be more fully filled during injection molding to form a strong connection, maintaining the connection effect even under conditions of frequent impacts.

[0042] Based on the above embodiments, such as Figure 3 As shown, in the composite connector housing provided in this embodiment, the connecting portion further includes a rubber-plastic flange 250. The rubber-plastic flange 250 is an extension structure based on the bearing area 20 to increase the contact area between the bearing area 20 and the enclosure area 10. Simultaneously, the rubber-plastic flange 250 is provided with a plurality of connecting holes 2510 spaced apart. The provision of the rubber-plastic flange 250 and the addition of connecting holes 2510 do not affect the main structure of the bearing area 20, thus avoiding structural damage to the functional area of ​​the bearing area 20 caused by the connection structure. Figure 3 and Figure 4 As shown, during the injection molding process of the enclosure area 10, the enclosure area 10 can fill and pass through the connecting hole 2510. By adjusting the molding die of the enclosure area 10, after the plastic material of the enclosure area 10 passes through the connecting hole 2510, limiting protrusions 120 with an outer diameter larger than the connecting hole 2510 are formed at both ends of the connecting hole 2510 in the axial direction. The enclosure area 10 forms a structure similar to a snap ring or buckle through the limiting protrusions 120, so that while the injection molding connection is being made, a secondary connection is achieved with the load-bearing area 20 through the snap-fit ​​structure, thereby further improving the bonding strength between the enclosure area 10 and the load-bearing area 20 and reducing the risk of disintegration due to relative displacement during use.

[0043] Furthermore, it should be noted that, similar to the adhesive strip, by adjusting the number and position of the connecting holes 2510 on the adhesive strip flange 250, different connection strengths and structural layouts can also be achieved. The setting of the connecting holes 2510 can also provide a certain amount of overflow space, so that the excess part of the enclosure area 10 during the molding process is filled in the connecting holes 2510 and forms the outer limiting protrusion 120, improving the neatness and aesthetics of the enclosure area 10.

[0044] Furthermore, in some embodiments of this disclosure, such as Figure 3 As shown, the first adhesive-pulling groove 230 has a dovetail groove structure. The opening of the first adhesive-pulling groove 230 with the dovetail groove structure is relatively narrow, while the area near the center of the bearing area 20 is wider than the opening. It can provide more space for the injection filling of the enclosure area 10 with a smaller opening. At the same time, after the enclosure area 10 is injection molded in the first adhesive-pulling groove 230, the dovetail groove structure of the first adhesive-pulling groove 230 can also lock the enclosure area 10 due to its small opening, achieving a mechanical locking effect similar to a mortise and tenon structure, thereby achieving a tighter connection between the enclosure area 10 and the bearing area 20. In other embodiments of this disclosure, the first adhesive-pulling groove 230 can also be configured as a combination of a dovetail groove and a cylindrical hole. This irregular structure provides a larger filling space, further increasing the contact area between the enclosure area 10 and the load-bearing area 20. It should also be noted that for enclosure area 10 structures with larger filling requirements, the first adhesive-pulling groove 230, based on the dovetail groove structure, can be configured with a larger filling area similar to a cylindrical hole to ensure effective connection between the enclosure area 10 and the load-bearing area 20. Furthermore, it should be noted that the second adhesive-pulling groove 240 can adopt a similar dovetail groove structure to simultaneously meet the requirements of injection molding connection and mechanical snap-fit; this will not be elaborated further here.

[0045] Furthermore, such as Figure 5 and Figure 6As shown, this disclosure also provides a split self-locking connector, which includes the composite connector housing provided in any of the above embodiments as a enclosure and insertion area. It should be noted that since the composite connector housing has the technical effects provided in any of the above embodiments, the split self-locking connector also has the technical effects provided in any of the above embodiments, which will not be repeated here. In addition, the split self-locking connector further includes a male connector assembly 30 and a female connector assembly 40. The female connector assembly 40 can be pre-assembled with the support area 20 on one side of the support area 20, and the insertion area on the female connector assembly 40 is located inside the support area 20. The male connector assembly 30 passes through an opening on one side wall of the enclosure area 10 and extends into the support area 20 to achieve insertion with the female connector assembly 40 within the support area 20. The male connector assembly 30 and the female connector assembly 40 are mated within the support area 20 and maintain a stable connection with the support of the support area 20 and the outer protective function of the enclosure structure.

[0046] Furthermore, in some embodiments of this disclosure, the split self-locking connector further includes a button assembly 50 to lock and unlock the male connector assembly 30 after it is connected to the female connector assembly 40. Specifically, the button assembly 50 mainly includes a pressing part 510, a connecting ring 520, and a return spring 530. The pressing part 510 is used for operation by a user to apply pressure to the button assembly 50, while the connecting ring 520 is disposed at the bottom of the pressing part 510, that is, on the side of the button assembly 50 facing the inside of the bearing area 20. The connecting ring 520 passes through the bearing area 20. The slotted structure is embedded inside the bearing area 20 and moves in a preset direction when the pressing part 510 is subjected to pressure. One end of the return spring 530 is predetermined inside the bearing area 20, and the other end abuts or is fixedly engaged with the bottom of the pressing part 510. When the pressing part 510 is subjected to pressure, it drives the connecting ring 520 to move and compresses the return spring 530. After the pressure on the pressing part 510 is removed, the compressed return spring 530 can lift the pressing part 510 to drive the connecting ring 520 back to the initial position.

[0047] Based on the operation of the button assembly 50, the outer wall of the male connector assembly 30, which is operated to move, is recessed with a insertion groove 310. During the compression process of the male connector assembly 30 and the female connector assembly 40 by the operator in the bearing area 20, the male connector assembly 30 passes through the connecting ring 520 and continues to extend until the insertion groove 310 on the male connector assembly 30 engages with the connecting ring 520. At this time, the male connector assembly 30 and the female connector assembly 40 are engaged, and the male connector assembly 30 is kept in a fixed position in the axial direction under the action of the connecting ring 520, without displacement and separation from the female connector assembly 40. This effectively prevents the male connector assembly 30 from loosening or falling off due to external force during use, thereby improving the reliability of the connector. Similarly, when it is necessary to unlock the male connector 30, the operator can apply pressure to the pressing part 510. When the pressing part 510 is under pressure, it drives the connecting ring 520 to move and leave the insertion slot 310. At this time, the locking structure of the male connector 30 in its axial direction is released, and it can be freely disengaged from the female connector 40, thus completing the unlocking and separation requirements. The structure is simple and effective, and the locking and unlocking operations can be completed without other tools, which improves the ease of use of the split self-locking connector.

[0048] To further optimize the above technical solution, in some embodiments of this disclosure, the split self-locking connector further includes a button plate 60 to further limit the button assembly 50. Specifically, the button plate 60 is fixed to the outer wall of the bearing area 20. When there is no external force, the pressing part 510 and the connecting ring 520 are in the initial state under the rebound action of the return spring 530. The pressing part 510 is kept in the initial position by the limiting block of the button plate 60 on the side opposite to the return spring 530. After the pressing part 510 completes a single pressing action, it can also be limited to the initial position by the button plate 60 after the return spring 530 springs up, thereby effectively preventing abnormal operation of the button assembly 50. It should also be noted that the limiting effect of the button plate 60 on the button assembly 50 is to ensure that the pressing part 510 in the button assembly 50 is flush with the outer wall surface of the bearing area 20. On the one hand, this makes the outer wall surface of the split self-locking connector flush, resulting in a more aesthetically pleasing appearance. On the other hand, the pressing part 510, which is flush with the outer wall surface of the bearing area 20, will not have a protruding structure based on the bearing area 20, thereby reducing the risk of misoperation due to external force. At the same time, the pressing part 510 will not be excessively embedded in the bearing area 20, which would make it difficult to operate.

[0049] Furthermore, in some embodiments of this disclosure, at least two reset springs 530 are provided in the button assembly 50, and the reset springs 530 are evenly distributed circumferentially on the pressing part 510, so that the pressing force of the button assembly 50 during operation can be evenly distributed on the reset springs 530, reducing the risk of skewing. At the same time, multiple reset springs 530 can provide uniform rebound force, thereby ensuring the positional accuracy of the pressing part 510 throughout the entire movement process, and better meeting the reliability requirements in complex usage environments.
