Hsd double ended connector

Abstract

This utility model belongs to the field of HSD connector technology and discloses an HSD double-headed connector, aiming to solve the problems of inconvenient maintenance and the need for complete replacement of traditional HSD double-type interfaces. This connector integrates and fixes two sets of standard HSD connectors through a double-headed housing. The housing includes upper and lower parts, which are initially positioned by the insertion rod and insertion hole, and then fixed by elastic clips and slots, preventing connector loosening. The fixing holes and bolts further reinforce the fixation, making it suitable for areas prone to vibration. During disassembly, a flathead screwdriver can push the hook through the hole to achieve separation, allowing the faulty connector to be removed and replaced individually, while the normal set can continue to work. It achieves similar functionality to a standard double-type interface while avoiding complete replacement, facilitating individual shielding, improving maintenance convenience and economy, ensuring stable signal transmission, and is suitable for automotive and other scenarios requiring connector flexibility and reliability.

Description

Technical Field

[0001] This utility model relates to the field of HSD connector technology, specifically to an HSD dual-head connector. Background Technology

[0002] In practical automotive electronic system layouts, there are numerous application scenarios requiring the simultaneous transmission of two independent sets of signals, such as dual-camera data acquisition and multi-module collaborative control signal transmission. To meet these needs, a common industry solution is to use the standard Rosenberger HSD double interface. Compared to the standard Rosenberger HSD interface, this double interface, through an integrated structural design, fixes two independent HSD interfaces side-by-side into a single unit, forming a standardized dual-interface module. This effectively avoids plugging errors caused by the identical shape of the two independent single interfaces.

[0003] However, the existing Rosenberger HSD double-type interface has gradually revealed many shortcomings affecting ease of use and cost-effectiveness in practical applications and maintenance. Firstly, in terms of maintenance, this type of interface uses an integrated, non-separable structure. When either of the two sets of interfaces is damaged, the faulty interface cannot be replaced individually; the entire double-type interface must be removed and replaced. During replacement, even the signal lines corresponding to the other set of interfaces that are not faulty must be disconnected and reconnected, not only adding unnecessary steps and extending maintenance time but also potentially causing additional damage to the signal lines due to repeated wiring, affecting transmission performance. Secondly, regarding adaptability in special scenarios, when it is necessary to separately shield one set of interfaces (e.g., rewiring in another location during maintenance) or temporarily wire separately for debugging, because both sets of interfaces share the same connection structure, the entire double-type interface must first be disconnected from external lines before reconnecting the signal line that does not need shielding to avoid faults (e.g., loops caused by additional wiring). This operation is not only cumbersome but may also cause signal transmission failures during normal operation, affecting the normal operation of the vehicle system. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-4 This utility model provides a technical solution: An HSD dual-head connector, comprising: First connector 1, and a first mating block 2 is provided on the right side of the first connector 1; The second connector 3 has a second mating block 4 on its left side; both the first connector 1 and the second connector 3 use existing HSD interface styles, and their plug ends are not limited. Any commonly used by those skilled in the art is applicable. The standard Rosenberger HSD ordinary type is usually used, which supports standard four-pin connectors.

[0018] The double-headed shell includes an upper part 5 and a lower part 6. The first connector 1 and the second connector 3 are both fixed between the upper part 5 and the lower part 6. A plug-in fixing structure is provided at the adjacent position of the upper part 5 and the lower part 6 of the double-headed connecting shell. The upper part 5 and the lower part 6 of the double-headed connecting shell are connected by the plug-in structure. The flexible snap-fit ​​structure includes two sets of slots 11 and two sets of flexible clips 12. The slots 11 are respectively located on the first mating block 2 and the second mating block 4. The flexible clips 12 are fixedly located at the bottom of the upper part of the double-headed housing 5 at the corresponding slots 11. The bottom of the flexible clips 12 is provided with hooks 13, and the flexible clips 12 and slots 11 are connected by the hooks 13. The upper part of the double-headed housing 5 and the lower part of the double-headed housing 6 can be detachably fixed through the insertion of the plug rod 9 and the plug hole 10 and the flexible snap-fit ​​structure. While fixed, the first connector 1 and the second connector 3 are not easy to loosen. The first connector 1 and the second connector 3 can be removed for replacement and maintenance by releasing the insertion and the flexible snap-fit. The first connector 1 and the second connector 3 are fixed by the upper part of the double-headed housing 5 and the lower part of the double-headed housing 6, which can achieve the effect of Rosenberger HSD double type interface. One of them can be removed for replacement and maintenance, and the remaining HSD signal can still be used normally. It is convenient for single-group shielding, easy to use, and highly practical.

[0019] The upper part 5 and the lower part 6 of the double-headed connecting shell are provided with grooves corresponding to the first connector 1 and the second connector 3. The first connector 1 and the second connector 3 are both fixed inside the double-headed connecting shell. The upper part 5 and the lower part 6 of the double-headed connecting shell are provided with separation protrusions 7 at the adjacent positions of the first connector 1 and the second connector 3.

[0020] The lower component 6 of the double-headed shell has a central connecting block 8 on the side opposite to the plug end. The first mating block 2 and the second mating block 4 after the first connector 1 and the second connector 3 are assembled have square notches corresponding to the central connecting block 8.

[0021] The plug-in structure includes multiple sets of plug-in rods 9 and multiple sets of plug-in holes 10. The plug-in rods 9 are located on the left and right sides of the lower double-headed shell component 6 and on the middle connecting block 8. The upper double-headed shell component 5 is provided with plug-in holes 10 corresponding to the plug-in rods 9. The upper double-headed shell component 5 and the lower double-headed shell component 6 are connected by plug-in rods 9 and plug-in holes 10.

[0022] Furthermore, notches 14 are provided on both the left and right sides of the upper component 5 of the double-headed housing, and fixing holes 15 are provided at each notch 14. The fixing holes 15 extend into the lower component 6 of the double-headed housing, and threaded sleeves are provided in the fixing holes 15. The threaded sleeves are usually set in the fixing holes 15 of the lower component 6 of the double-headed housing. Using a capped bolt, the nut is pressed against the screw of the upper component 5 of the double-headed housing and screwed into the threaded sleeve, so that the upper component 5 and the lower component 6 of the double-headed housing can be firmly fixed. This is suitable for some areas prone to vibration, avoids the defect of jamming, and prevents the upper component 5 and the lower component 6 of the double-headed housing from loosening and falling off due to long-term vibration.

[0023] Furthermore, the first mating block 2 and the second mating block 4 are provided with a notch 16 at the opening of the corresponding slot 11. Since the hook 13 protrudes, the notch 16 at the slot entrance enlarges the entrance, making it easier to insert the elastic clip 12 and the hook 13 into the slot 11.

[0024] Furthermore, a deformation slit 17 is provided on the side of the elastic clip 12 away from the hook 13. The deformation slit 17 facilitates the deformation of the elastic clip 12 to the side away from the hook 13, provides deformation space, makes it easy to insert the elastic clip 12 into the bottom of the slot 11, and improves the durability of the snap-fit ​​structure.

[0025] Furthermore, a bevel 18 is provided on the side of the hook 13 near the insertion end. A flathead screwdriver relief hole 19 is provided on the first mating block 2, the second mating block 4, and the separating protrusion 7, and the flathead screwdriver relief hole 19 connects to the two sets of slots 11. After the hook is engaged, the outer side of the hook 13 is placed outside the slot 11. At this time, a flathead screwdriver can be inserted from the flathead screwdriver relief hole 19. The two ends of the screwdriver abut against the bevel 18. As the screwdriver goes deeper, it will abut against the bevel 18 and deform it away from the screwdriver, that is, the hook 13 will retract. At this time, the upper part 5 of the double-headed connecting shell can be separated vertically upward from the lower part 6 of the double-headed connecting shell. This can avoid the hardening of the plastic material after long-term use and can easily separate the upper part 5 and the lower part 6 of the double-headed connecting shell.

It is provided with a groove matching the connector, a partition protrusion 7, a middle connecting structure block 8, a plug rod 9, and a fixing hole 15, providing the connector with an installation base and positioning structure. Separating convex 7: It is set at the position adjacent to the first connector 1 and the second connector 3 on the upper part 5 and the lower part 6 of the double-headed connecting shell, forming a physical isolation between the two sets of connectors and avoiding contact interference between adjacent parts; Interconnecting structural block 8: Located on the side of the lower component 6 of the double-headed connecting shell away from the plug end, it can mate with the square notch of the first mating block 2 and the second mating block 4 to limit the horizontal displacement of the connector and assist in positioning; Plug-in rod 9: It is set on the left and right sides of the lower part of the double-headed connecting shell 6 and on the middle connecting structure block 8. It cooperates with the plug-in hole 10 of the upper part of the double-headed connecting shell 5 to achieve the initial positioning of the upper and lower parts of the double-headed connecting shell and restrict the horizontal relative movement. Insertion hole 10: It is opened on the upper part 5 of the double-headed connecting shell and corresponds to the insertion rod 9 of the lower part 6 of the double-headed connecting shell. It provides initial fixation and positioning for the upper and lower parts of the double-headed connecting shell through insertion. Slot 11: It is respectively set on the first mating block 2 and the second mating block 4, and engages with the hook 13 of the elastic clip 12 to fix the connector to the double-headed shell, and connects to the flathead screwdriver hole 19; Elastic clip 12: It is fixed at the bottom of the double-headed connecting shell component 5 corresponding to the slot 11. The bottom is provided with a hook 13 and a deformation cut 17 is provided on the side opposite to the hook 13. The connector is locked in the double-headed connecting shell by snapping. Hook 13: Set at the bottom of the elastic clip 12, with a bevel 18 on the side near the insertion end, which can engage with the inner wall of the slot 11 to achieve elastic fixation, and can disengage from the slot 11 after being deformed by force to assist in disassembly. Slot 14: Located on the left and right sides of the double-headed housing component 5, the slot is provided with fixing holes 15, providing space for fixing holes 15 and facilitating bolt operation; Fixing hole 15: It is set at the notch 14 and extends into the lower part 6 of the double-headed shell. It has a built-in screw sleeve and can be used with a capped bolt to strengthen the fixation of the upper and lower parts of the double-headed shell. It is suitable for areas prone to vibration. Slot inlet oblique notch 16: Set at the position of the opening of the slot 11 corresponding to the first mating block 2 and the second mating block 4, to enlarge the slot 11 inlet, so as to facilitate the insertion of the elastic clip 12 and the hook 13 into the slot 11; Deformation notch 17: Located on the side of the elastic clip 12 away from the hook 13, providing deformation space for the elastic clip 12, making it easier for it to be inserted into the bottom of the slot 11, and improving the durability of the snap-fit ​​structure; Angled surface 18: Located on the side of the hook 13 near the insertion end, it can contact the end of a flathead screwdriver and push the hook 13 to deform through leverage force to assist in releasing the engagement; Flathead screwdriver recess 19: It is formed on the first mating block 2, the second mating block 4 and the partition protrusion 7, connecting the two sets of slots 11, providing an operating channel for the flathead screwdriver, and assisting in the separation of the upper and lower parts of the double-headed shell and the disassembly of the connector.

[0027] Working principle: The upper component 5 and lower component 6 of the double-headed housing are respectively pre-set with grooves that match the shape of the first connector 1 and the second connector 3. Separating protrusions 7 are provided at adjacent positions of the two sets of connectors. During assembly, the standard Rosenberger HSD type first connector 1 and second connector 3 are inserted into the corresponding grooves. The separating protrusions 7 physically isolate the two sets of connectors, preventing contact interference between adjacent components. Simultaneously, the first mating block 2 of the first connector 1 and the second mating block 4 of the second connector 3 precisely align with the middle connecting block 8 of the lower component 6 of the double-headed housing, away from the insertion end, through their pre-reserved square notches. This further restricts the horizontal displacement of the connectors, ensuring that the two sets of connectors always remain aligned side-by-side, laying the foundation for subsequent fixing and functional implementation.

[0028] During assembly, multiple sets of plug-in rods 9 on the left and right sides of the lower component 6 of the double-headed connecting shell and on the middle connecting block 8 will precisely plug into the corresponding plug-in holes 10 of the upper component 5 of the double-headed connecting shell, forming a preliminary positioning and restricting the relative movement of the upper and lower components in the horizontal direction. Subsequently, the two sets of elastic clips 12 at the bottom of the upper component 5 of the double-headed connecting shell will gradually embed into the slots 11 of the first mating block 2 and the second mating block 4 as the upper and lower components are attached. The hooks 13 at the bottom of the elastic clips 12 will engage with the inner wall of the slots 11 to form a stable elastic locking structure, ultimately realizing the detachable fixing of the upper and lower components of the double-headed connecting shell. At the same time, through the cooperation of the clips and the slots 11, the first connector 1 and the second connector 3 are firmly locked in the connecting shell to prevent the connectors from loosening during use and to ensure the stability of signal transmission.

[0029] In areas prone to vibration, the fixing holes 15 at the notches 14 on both sides of the double-headed connecting shell can be used for reinforcement. The combination of the built-in screw sleeve and the capped bolt can further lock the upper and lower parts, making up for the shortcomings of the elastic snap-fit ​​in the strong vibration environment and preventing the connecting shell from loosening. During disassembly and maintenance, the design of the notch 16 at the entrance of the slot and the deformation notch 17 of the elastic clip 12 can reduce the snap-fit ​​resistance. When the elastic clip 12 is hardened due to long-term use and is difficult to disassemble, a flathead screwdriver can be inserted into the flathead screwdriver hole 19 on the first mating block 2, the second mating block 4 and the partition protrusion 7. The end of the screwdriver is used to press against the inclined surface 18 of the hook 13. Through the leverage force, the hook 13 is pushed to deform in the direction away from the slot 11, so that the clip is separated from the slot 11. Then the upper and lower connecting shells can be separated vertically, and the faulty connector can be taken out for individual replacement without disassembling the signal line of the normal connector.

[0030] In terms of functionality, the integrated fixation of two sets of standard HSD connectors via a double-headed shell simulates the dual-signal transmission function of the Rosenberger HSD double-type interface. Furthermore, its detachable modular design solves the problem of requiring complete replacement of the entire double-type interface after a failure. When replacing a faulty connector, the normal connectors remain in their original positions and continue operating without interrupting overall signal transmission. If shielding of a single signal set is required, the target connector can be removed individually without disconnecting the entire connection, significantly improving ease of use and maintenance economy, and meeting the flexible application needs of complex scenarios such as automotive applications.
