Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle component technology, and more specifically, to a vehicle shielded electrical connector device. Background Technology
[0002] Vehicle electrical connectors are critical components of a vehicle's electrical system. They are typically located between the vehicle's power supply and interactive control components (such as the central control screen and onboard computer) and instrument clusters. They are used for the transmission and distribution of electrical signals and to shield and protect electrical components from damage caused by harsh external environments. The main body of this connector is a housing structure, mounted on the front frame of the vehicle's cab. One side has connecting structures at both ends, typically holes or clips, for securing the connector with bolt holes or snap-fit mechanisms. The other side has wiring holes for wires to pass through to the interactive control and instrument clusters. The hollow interior of the housing houses electrical components such as switches, relays, and splitters to ensure stable circuit operation.
[0003] However, existing vehicle electrical connector components suffer from insufficient structural strength in practical use. Vehicles are continuously subjected to vibration and impact during operation, especially in harsh road conditions or during engineering vehicle operations, where the vibration is more intense. Long-term exposure to these vibrations can easily lead to fatigue deformation or even breakage at the housing connections or weak points. Furthermore, vehicle operating environments may experience extreme temperature variations (such as extreme cold or intense sunlight), causing stress concentration in the housing material due to thermal expansion and contraction, further accelerating material fatigue and reducing structural reliability. Once the housing is damaged, internal electrical components may fail due to loosening, short circuits, or poor contact, affecting the stability of the vehicle's electrical system and even posing safety hazards. Currently, conventional solutions to these problems include increasing the housing wall thickness or using high-strength engineering plastics. However, simply increasing the wall thickness increases material costs and weight, while replacing materials with high-performance materials may lead to a significant increase in production costs.
[0004] In summary, existing vehicle electrical connector devices suffer from technical problems such as housing structures that are not durable for long-term use and are prone to fatigue damage. Utility Model Content
[0005] The technical problem to be solved by this utility model is that the housing structure of the electrical connector device in existing vehicles is not durable for long-term use and is prone to fatigue damage.
[0006] To address the aforementioned problems, this utility model provides a vehicle shielded electrical connector device, comprising an integrally formed connector front axle and connector rear axle, with a hollow cavity formed between them. The side wall of the connector front axle is provided with a wire hole structure communicating with the hollow cavity. Each end of the connector front axle and connector rear axle is provided with a mounting hole structure for mounting and fixing to the vehicle frame. The connector rear axle has a plate extension integrally connected to one side of the mounting hole structure. The end of the plate extension is provided with a reinforcing hole, the direction of which is parallel to the mounting hole structure. The distance between the wire hole structure and the mounting hole structure is greater than the distance between the wire hole structure and the reinforcing hole. The reinforcing hole is used for mounting and fixing with an additional positioning clip on the vehicle frame.
[0007] This utility model provides an optimized shielded electrical connector device. Based on the existing commonly used structure, it adds a plate extension to the connector rear axle structure on one side of the overall housing structure. This structure increases the plate width on that side of the housing, effectively avoiding stress concentration. A reinforcing hole is provided at the end of the added plate extension, thereby increasing the connection and fixing points between the electrical connector housing and the vehicle frame. Furthermore, the added plate extension is of unequal length to the original connector rear axle; that is, the reinforcing hole and the mounting hole structure of the connector rear axle are not at the same height. They form a stepped surface with a height difference for connection and fixing to the vehicle frame, further improving the installation strength and significantly enhancing the structural strength of the electrical connector. This effectively solves the technical problem of existing vehicle electrical connector devices having housing structures that are not durable for long-term use and are prone to fatigue damage.
[0008] As a preferred embodiment, the plate extension is a beam structure with a T-shaped cross-section, and one side of the plate extension is integrally formed and connected to the side plate of the connector rear axle. This design optimizes the overall structure of the plate extension. The T-shaped cross-section of the plate extension greatly increases the strength of the added plate. The integral formation of the plate extension with the side plate of the connector rear axle constitutes a structure similar to an I-beam, effectively improving the shell strength, especially the torsional resistance.
[0009] As a preferred embodiment, the edge of the side plate of the connector rear axle extends to the outer edge of the reinforcing hole, and a first rib parallel to its length direction is provided on the outer edge of the plate extension. The edge of the outer rib also extends to the outer edge of the reinforcing hole. This design further enhances the overall compressive and torsional strength of the connector housing by adding ribs. The edges of the side plate and the first rib extend to the outer edge of the reinforcing hole in the plate extension, providing focused reinforcement at the connection point between the connector housing and the frame, thus preventing breakage due to stress concentration at the connection point.
[0010] As a preferred embodiment, the plate extension has a grid-shaped convex-concave structure on the side facing the hollow cavity. This design further optimizes the plate design of the plate extension based on the aforementioned stiffener design. Since ensuring the strength of the plate at the additional location generally requires thickening the plate, this technical solution uses a convex-concave grid structure instead of thickening the plate. This improves the tensile and compressive strength of the plate extension while avoiding material waste caused by thickening the plate, thus saving material and reducing material costs.
[0011] As a preferred embodiment, the connector rear bridge has a second stiffening plate integrally connected to its side edge opposite to the plate extension, and the shape of the second stiffening plate is consistent with the edge shape of the connector rear bridge. This design further enhances the structural strength of the connector rear bridge; the addition of the second stiffening plate results in a simple structure with a good strength improvement effect.
[0012] As a preferred embodiment, the other edge of the second stiffener extends to the outer edge of the mounting hole structure of the connector front bridge, and the second stiffener protrudes from both the inner and outer sides of the connector front bridge's plate surface. This design further optimizes the stiffener structure based on the aforementioned second stiffener structure, extending the stiffener to the outer edge of the connector front bridge and its mounting hole structure, thereby improving the overall integrity of the connector housing structure.
[0013] As a preferred embodiment, the inner protrusion of the connector front bridge has a third and a fourth rib distributed on both sides of the second rib. This design increases the structural strength of the protruding plate portion of the connector housing by increasing the number of ribs.
[0014] As a preferred embodiment, both the mounting hole structure and the reinforcing hole have an integrally formed thickened hole wall structure on their outer edges. This design thickens the structure around the connecting holes of the connector housing, avoiding stress concentration at the mating position.
[0015] As a preferred embodiment, the connector front axle, connector rear axle, and the end of the plate extension are each integrally connected to a protruding insert plate structure on the outer wall of the mounting hole structure and the reinforcing hole, respectively. This insert plate structure is used to engage with a protruding slot on the frame surface. Based on the aforementioned structure that mounts the connector to the frame via the hole structure, this design provides a protruding plate-like slider on the outer side of the mounting hole. This structure engages with the slot structure on the frame, further enhancing the stability of the installation. Attached Figure Description

[0021] This utility model provides a vehicle shielded electrical connector device, comprising an integrally formed connector front axle 1 and connector rear axle 2, forming a hollow cavity between them. The connector front axle 1 has a wire hole structure 4 communicating with the hollow cavity on its side wall. Each end of the connector front axle 1 and connector rear axle 2 has a mounting hole structure 3 for mounting and fixing to the vehicle frame. The connector rear axle 2 has a plate extension portion 5 integrally connected to one side of the mounting hole structure 3. The end of the plate extension portion 5 has a reinforcing hole 6, the direction of which is parallel to the mounting hole structure 3. The distance between the wire hole structure 4 and the mounting hole structure 3 is greater than the distance between the wire hole structure 4 and the reinforcing hole 6. The reinforcing hole 6 is used for mounting and fixing to an additional positioning clip on the vehicle frame.
[0022] This utility model provides an optimized shielded electrical connector device. Based on the existing commonly used structure, it adds a plate extension 5 to the connector rear axle 2 structure on one side of the overall housing structure. This structure increases the width of the plate surface on that side of the housing, effectively avoiding stress concentration. A reinforcing hole 6 is provided at the end of the added plate extension 5, thereby increasing the connection and fixing points between the electrical connector housing and the vehicle frame. Furthermore, the added plate extension 5 is of unequal length to the original connector rear axle 2; that is, the reinforcing hole 6 and the mounting hole structure 3 of the connector rear axle 2 are not at the same height. They form a stepped surface with a height difference for connection and fixing to the vehicle frame, further improving the installation strength and significantly enhancing the structural strength of the electrical connector. This effectively solves the technical problem of existing vehicle electrical connector devices having housing structures that are not durable for long-term use and are prone to fatigue damage.
[0023] As a preferred embodiment, the plate extension 5 is a beam structure with a T-shaped cross-section, and one side of the plate extension 5 is integrally formed and connected to the side plate 10 of the connector rear axle 2. This design optimizes the overall structure of the plate extension 5. The T-shaped cross-section design of the plate extension 5 greatly increases the strength of the added plate. The plate extension 5 and the side plate 10 of the connector rear axle 2 are integrally formed, forming a structure similar to an I-beam, which effectively improves the shell strength, especially the torsional resistance.
[0024] In the technical solution provided in this embodiment, the edge of the side plate 10 of the connector rear axle 2 extends to the outer edge of the reinforcing hole 6, and the outer edge of the plate extension 5 is provided with a first stiffener 7 parallel to its length direction. The edge of the outer stiffener also extends to the outer edge of the reinforcing hole 6. This design further improves the overall compressive and torsional strength of the connector housing by adding stiffeners. The edges of the side plate 10 and the first stiffener 7 both extend to the outer edge of the reinforcing hole 6 of the plate extension 5, focusing on reinforcing the hole position where the connector housing connects to the frame, and avoiding breakage at the connection position due to stress concentration.
[0025] In the technical solution provided in this embodiment, the plate extension 5 has a grid-shaped concave-convex structure 11 on the side plate 10 facing the hollow cavity. This design further optimizes the plate design of the plate extension 5 based on the aforementioned stiffener design. Since ensuring the strength of the plate at the additional position generally requires thickening the plate, this technical solution uses a concave-convex grid structure instead of thickening the plate. This improves the tensile and compressive strength of the plate extension 5 while avoiding material waste caused by thickening the plate, thus saving material and reducing material costs.
[0026] In the technical solution provided in this embodiment, a second stiffening plate 8 is integrally connected to the side edge of the connector rear bridge 2 on the side opposite to the plate extension 5, and the shape of the second stiffening plate 8 is consistent with the edge shape of the connector rear bridge 2.

This design further optimizes the stiffener structure based on the aforementioned second stiffener 8 structure, extending the stiffener to the outer edge of the connector front bridge 1 and its mounting hole structure 3, thereby improving the overall integrity of the connector housing structure.
[0028] In the technical solution provided in this embodiment, the inner protrusion of the connector front bridge 1 is provided with a third stiffener 12 and a fourth stiffener 13 distributed on both sides of the second stiffener 8. This design increases the structural strength of the protruding plate parts of the connector housing by increasing the number of stiffeners.
[0029] In the technical solution provided in this embodiment, the outer edges of both the mounting hole structure 3 and the reinforcing hole 6 are integrally formed with a thickened hole wall structure. This design thickens the structure around the connecting hole of the connector housing to avoid stress concentration at the mating position.
[0030] In the technical solution provided in this embodiment, the ends of the connector front bridge 1, connector rear bridge 2, and plate extension 5 are integrally connected to the outer walls of the mounting hole structure 3 and the reinforcing hole 6, respectively, with protruding insert plate structures 9.

Based on the aforementioned structure that mounts the connector to the frame through the hole structure, this design provides a protruding plate-like slider on the outside of the mounting hole. This structure, through its insertion and engagement with the slot structure on the frame, further enhances the stability of the installation.
