Description

Technical Field

[0001] The utility model relates to the technical field of steering systems, in particular to a harness plug installation tool for a torque sensor. Background Art

[0002] During the production process of the torque sensor, the sensor interface needs to be installed and connected to the sensor harness to support the sensor's power supply and signal transmission. Since the sensor harness end is relatively soft and lacks other structural support, the harness needs to be manually installed by workers on the production line to insert the sensor interface. This process has uncertainties caused by human factors. In extreme cases, it is easy to cause the harness interface to be loose, and when subsequent external force intervenes, the interface is prone to loosening, making it impossible to power the sensor and transmit torque signals, which will eventually lead to functional failure of the vehicle's steering system and threaten the driver's life safety. Summary of the Invention

[0005] The positioning needle is a square columnar structure, one end of the positioning needle is connected to the upper position of the front end surface of the wiring harness interface claw, and the other end of the positioning needle is a tapered structure.

[0006] The wiring harness interface claw is an L-shaped module structure, and the lower part of the wiring harness interface claw is an N-shaped hollow structure. The top of the N-shaped hollow structure is provided with a slide rail groove that matches the slide rail, and the lower rear side of the wiring harness interface claw is connected to the wiring harness guide groove.

[0007] A mounting groove for mounting a wiring harness plug is provided at the lower front end of the wiring harness interface claw.

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] The function of the sensor harness interface is to fix the sensor harness, realize the electrical connection between the sensor and the harness, transmit the power signal of the steering system main control unit to the sensor, and transmit the torque signal measured by the sensor to the harness and send it to the main control unit. It is the physical signal port of the torque sensor.

[0020] In the existing structure, to install the sensor wiring harness, production line workers need to manually install it by inserting the sensor wiring harness plug into the wiring harness interface on the side of the sensor. This step is only one part of the overall process of installing the sensor into the steering gear. The overall process is basically automated by mechanical equipment, but this step still requires manual intervention by workers.

[0021] First, because the wiring harness is relatively soft and the sensor housing lacks structural support, manual intervention is required for installation. This inevitably introduces uncertainty due to human factors, making it difficult to quantify and standardize. In extreme cases, this can lead to a loose connection between the sensor harness and the sensor's wiring harness interface. Thermal or mechanical shock during subsequent vehicle installation or even end-user use can cause the harness connector to loosen, leading to a failure in the sensor torque signal transmission and a steering system error, posing a safety threat to the driver. Second, as mentioned above, inserting the sensor harness connector into the wiring harness interface is only one part of the entire sensor installation process, which is largely completed by large-scale automated machinery. This step alone requires manual intervention, placing the worker in direct contact with the equipment's mechanical structure and the sensor, which inadvertently increases the potential risk to the worker's life. Third, before installing the harness, the worker must first ensure that the entire equipment is in a suspended state. Furthermore, the wiring harness installation time is uncertain, which indeed increases the overall process cycle time.

[0022] like Figures 1 to 3 As shown, a wiring harness plug installation tool for a torque sensor is designed. The installation tool includes a positioning needle, a positioning pin, a wiring harness interface claw, a slide rail, and a wiring harness guide groove. The bottom of the wiring harness interface claw 2 is connected to the wiring harness guide groove 4, and a slide rail 3 is provided in the wiring harness guide groove 4. The front end surface of the wiring harness interface claw 2 is connected to the positioning needle 1, and a positioning pin 5 is connected to one side of the wiring harness guide groove 4.

[0023] The positioning needle 1 is a square columnar structure, one end of the positioning needle 1 is connected to the upper position of the front end surface of the wiring harness interface claw 2, and the other end of the positioning needle 1 is a tapered structure.

[0024] The wiring harness interface claw 2 is an L-shaped module structure, and the lower part of the wiring harness interface claw 2 is an N-type hollow structure. The top of the N-type hollow structure is provided with a slide rail groove that matches the slide rail 3. The lower rear side of the wiring harness interface claw 2 is connected to the wiring harness guide groove 4.

[0025] A mounting groove for mounting a wiring harness plug is provided at the lower front end of the wiring harness interface claw 2 .

[0026] The slide rail 3 is embedded in the wire harness guide groove 4 , and the top of the slide rail 3 matches the slide rail groove of the wire harness interface claw 2 .

[0027] The harness guide groove 4 is composed of two rectangular modules, and the two rectangular modules are connected at the lower rear side of the harness interface claw 2 .

[0028] The positioning pin 5 is connected obliquely to one side of the harness guide groove 4 .

[0029] like Figure 4 , Figure 5 As shown, the harness interface claw 2 below the positioning needle 1 of the installation tool of the present invention will fix the harness plug 10 of the sensor harness, and then the positioning pin 5 will mechanically cooperate with the corresponding positioning slot 8 on the sensor housing to ensure that the relative position between the entire installation tool and the sensor is fixed. Then the positioning needle 1 will identify the positioning needle hole 6 on the harness interface 7 of the sensor, and move with the harness plug 10 to the harness interface 7 to complete the entire installation process.

[0030] The mutual cooperation between the positioning pin 5 of the installation tool of the present invention and the positioning slot 8 on the sensor housing, and the mutual cooperation between the positioning needle hole 6 and the positioning needle 1, enable the fixed wiring harness plug 10 to be transported to the wiring harness socket 7 more accurately to avoid spatial position offset, and the relative position relationship between the positioning needle hole 6 and the positioning needle 1 can be quantified, which means that the wiring harness plug 10 fixed with the positioning needle 1 can also be accurately controlled in the process of matching with the wiring harness socket 7, which provides a good guarantee for whether the wiring harness plug 10 is accurately inserted into the wiring harness interface 7; the above-mentioned wiring harness plug 10 installation process is completely completed automatically by mechanical devices, which can completely avoid human intervention and eliminate potential hidden dangers caused by contact between workers and equipment; this method makes the entire installation process precise and controllable, greatly avoids uncertainties before optimization, reduces cycle time, and improves production efficiency.

[0031] At present, the utility model has been successfully applied to the production of torque sensors, and its actual effect is in line with expectations.
