Description

Technical Field

[0001] The utility model relates to the technical field of EGR valves, and more specifically to a guiding connector for an EGR valve. Background Art

[0002] The female terminal of a conventional EGR valve sensor assembly is connected to the male terminal of a motor, and a U-shaped female terminal insert is often used. However, during the process of inserting the male terminal of the motor into the U-shaped female terminal insert, it is easy to insert it obliquely. In this case, the male terminal of the motor still contacts the female terminal and cannot be identified during the subsequent function detection process, resulting in the product flowing out. Under the long-term use conditions of the customer's harsh vehicle, there will be problems such as poor contact, resulting in abnormal operation of the product. Conventional detection methods can only confirm by 100% inspection through X-rays, resulting in additional investment in production lines and personnel. Summary of the Invention

[0003] The technical problem to be solved by the utility model is to provide a guiding connector for an EGR valve, so that the male terminal of the motor can be correctly inserted into the female terminal of the sensor assembly, and the qualified rate of the product is improved.

[0004] To solve the above technical problems, the following technical solutions are adopted by the utility model.

[0005] A guiding connector for an EGR valve includes a sensor housing. A cavity for inserting the male terminal of the motor is arranged inside the sensor housing; a metal body is arranged at the top of the cavity of the sensor housing, and a guiding groove for guiding the insertion of the male terminal of the motor is stamped in the middle of the metal body, and a female terminal connected to the male terminal of the motor is arranged below the metal body.

[0006] Further optimizing the technical solution, the female terminal is two left and right V-shaped elastic pieces, and the gap at the bottom ends of the two elastic pieces is smaller than the thickness of the contact surface of the male terminal of the motor.

[0007] Further optimizing the technical solution, the head of the male terminal of the motor is stamped into a barb structure.

[0008] Further optimizing the technical solution, the thickness of the barb structure is smaller than the thickness of the guiding groove, and the thickness of the barb structure is greater than the gap between the two elastic pieces after the male terminal of the motor is inserted into the guiding groove.

[0009] Due to the adoption of the above technical solutions, the following technical progress is achieved by the utility model.

[0010] A guiding connector for an EGR valve provided by the present utility model has a guiding groove opened on a metal body, enabling a male motor terminal to be correctly inserted into a female terminal, further ensuring that the male motor terminal will not be inserted obliquely, guaranteeing the qualified rate of the product. At the same time, a male motor terminal with a barb structure and a V-shaped elastic sheet structure are adopted to ensure that the male motor terminal cannot be pulled out after being inserted into the female terminal, enabling rapid identification on the production line. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Wherein: 1. Metal body, 2. Female terminal, 3. Guiding groove, 4. Sensor housing, 5. Male motor terminal. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] The present utility model will be further described in detail below in conjunction with the drawings and specific embodiments.

[0015] A guiding connector for an EGR valve, in combination with Figure 1 as shown, includes a sensor housing 4. A cavity is provided inside the sensor housing 4 for the male motor terminal 5 to be inserted.

[0016] At the top of the cavity of the sensor housing 4, a metal body 1 is provided. A guiding groove 3 is stamped in the middle of the metal body 1 to guide the insertion of the male motor terminal 5, ensuring that the male motor terminal 5 can be correctly inserted along the guiding groove 3.

[0017] A female terminal 2 is provided below the metal body 1. The female terminal 2 is connected to the male motor terminal 5. The female terminal 2 is two left and right V-shaped elastic sheets formed by stamping the metal body. The gap at the bottom ends of the two elastic sheets is smaller than the thickness of the contact surface of the male motor terminal 5), ensuring that after the male motor terminal 5 is inserted into the female terminal 2, the elastic force of the elastic sheets ensures reliable contact between the metal body 1 and the male motor terminal 5.

[0018] The head of the male motor terminal 5 is stamped into a barb mechanism. The thickness of the barb structure is smaller than the thickness of the guiding groove 3, and the thickness of the barb structure is greater than the gap between the two elastic sheets after the male motor terminal 5 is inserted into the guiding groove, ensuring that the male motor terminal cannot be smoothly pulled out after being inserted.

[0019] The schematic connection diagram when the male motor terminal of the present utility model is inserted is as Figure 2As shown in the figure, the male terminal of the motor is inserted into the female terminal through the guiding groove. At the same time, the barb mechanism of the male terminal of the motor is designed to ensure that the male terminal of the motor cannot be pulled out after being inserted into the female terminal. During operation, after installing the sensor housing of the EGR or throttle valve, pull the sensor housing outwards. If it cannot be pulled out, it indicates that the male terminal of the motor has been correctly inserted into the female terminal of the sensor assembly, enabling rapid identification on the production line. At the same time, due to the existence of the guiding groove of the female terminal, it can guide the male terminal of the motor, further ensuring that the male terminal of the motor is not inserted incorrectly and guaranteeing the qualification rate.
