Description

Technical Field

[0001] This utility model belongs to the field of gearbox technology, specifically relating to a protective device for connectors and wiring harnesses. Background Technology

[0002] In the current commercial vehicle market, automatic transmissions are gradually becoming the mainstream. For automatic transmissions, more and more sensors and solenoid valves are integrated. Wiring harnesses are needed to receive sensor signals and transmit them to the control unit in the actuator. After analysis, control commands are then transmitted to each solenoid valve to control the automatic shifting of the transmission. In this process, the wiring harness acts as the medium for signal transmission, playing a crucial role.

[0003] There are usually two large wiring harness interfaces on the transmission actuator. One is responsible for communication inside the transmission, and the other is responsible for communication between the transmission and the vehicle. Conventional wiring harness interfaces are just connectors. Due to the lack of protection, firstly, external impacts can cause physical damage to the connectors and wiring harnesses, affecting normal communication. Secondly, severe vibrations may cause them to fall off or the pins to come loose, resulting in obstructed signal transmission. In severe cases, this can lead to the vehicle being unable to drive normally. Summary of the Invention

[0029] The utility model is not limited to the following specific embodiments. All equivalent modifications made based on the technical solution of this application fall within the protection scope of this utility model.

[0030] It should be noted that the directional terms mentioned in this article, such as "inner cavity", "upper part" and "end", are consistent with the specific directions on the paper in the drawings of the specification or the corresponding directions of the space shown in the drawings; all components and devices in this utility model, unless otherwise specified, adopt components and devices known in the prior art.

[0031] Example

[0032] This embodiment discloses a protective device for connectors and wire harnesses, including a protective cover 2 connected to the upper part of the actuator housing 1 and covering the connector 4 and wire harness 5. The upper part of the protective cover 2 is provided with multiple reinforcing ribs 2-1, and semi-circular slots 3 are provided at both ends of the protective cover 2 to connect the inner cavity of the protective cover 2 with the outside.

[0033] Its functions are as follows: the protective cover 2 completely covers the space above the connector 4 and the wiring harness 5, which can prevent external force impact from above. At the same time, the reinforcing ribs 2-1 increase the strength of the protective cover 2 and avoid direct damage to the connector 4 and the wiring harness 5. Meanwhile, the vehicle experiences shaking and vibration during driving. For the integrated design of the connector 4 and the wiring harness 5, the semi-circular bayonet 3 can directly support and fix the wiring harness 5. The whole system protects the connector 4 and the wiring harness 5, ensures normal communication, and avoids signal transmission obstruction.

[0034] The protective cover 2 disclosed in this embodiment includes a protective plate 2a that is horizontally or inclined upward above the housing 1 and covers the connector 4 and wire harness 5, and also includes a connecting plate 2b that connects the two ends and one side of the protective plate 2a to the upper part of the housing 1; and a connecting plate 2b with any semi-circular bayonet 3 located at any end of the protective cover 2.

[0035] The protective cover 2 can be integrated with the actuator housing 1; in actual production, it can be die-cast or CNC machined. Figure 4 As shown, the protective plate 2a is designed horizontally, but it can also be designed to be angled upwards. The advantage of the angled upward design of the protective plate 2a is that it can prevent the accumulation of rainwater, avoid the accumulation of rainwater, oil, etc., reduce the occurrence of rust, and reduce the possibility of the protective plate 2a being stepped on. The advantage of the horizontal design of the protective plate 2a is that it does not increase the height of the actuator, which is more conducive to the matching of the whole vehicle. In practical applications, the choice can be made according to the needs.

[0036] In this embodiment, each reinforcing rib 2-1 is evenly distributed on the upper part of the protective plate 2a and extends from the connecting plate 2b on one side of the protective plate 2a to the shell 1 to increase the strength of the protective cover 2.

[0037] The protective plate 2a disclosed in this embodiment has multiple notches 9 that correspond one-to-one with the bolt holes 7 on the actuator housing 1. The number of notches 9 depends on the number of bolt holes 7. Each notch 9 is located between two adjacent reinforcing ribs 2-1. The notches 9 are elliptical in shape, facilitating the tightening or loosening of the actuator bolts by inserting a torque wrench. A rubber cap 8 matching the structure is provided on the notch 9 to prevent rainwater, oil, etc., from corroding the connector 4 and wiring harness 5. The rubber cap 8 can seal the notch of the protective plate 2 and is easy to install and remove. Generally, the height of the rubber cap 8 after installation is no higher than the longitudinal ribs of the protective plate 2 to prevent damage to the rubber cap 8 caused by trampling or other actions.

[0038] In this embodiment, for scenarios using braided wire harness 5, each semi-circular bayonet 3 has two through holes, through which cable ties 6 pass in sequence to further secure the wire harness.

[0039] In this embodiment, the actuator housing 1 is cast using both top-and-bottom and right-side mold openings. The semi-circular bayonet 3 and its small holes are easily cast and do not require changes to the mold parting method; only minor modifications to existing molds are needed, resulting in very low cost. The semi-circular bayonet 3 can be designed with a horizontal opening or a vertical upward opening, depending on the actual application. Because the semi-circular bayonet 3 supports and secures the wiring harness 5, even under severe vibrations in harsh working conditions, the connector 4 is unlikely to loosen, ensuring the reliability of gearbox signal transmission during vehicle operation. This protection system is highly versatile, capable of protecting various types and sizes of connectors 4 and wiring harnesses 5, and is structurally reliable and easy to maintain.

However, this disclosure is not limited to the specific details of the above embodiments.
