Description

Technical Field

[0001] This utility model relates to the field of solenoid valve technology, specifically to a PIN pin connection structure for a solenoid valve. Background Technology

[0002] Solenoid valves are typically connected to the circuit board via pins. Traditionally, the pins of solenoid valves are connected to the copper wires using soldering, a complex process that can easily deform the pins.

[0003] Traditional solenoid valve pins typically have square holes and a relatively simple insertion section at the pin tip. This entire structure is mounted on automotive braking systems, which experience significant vibrations. During these vibrations, the pins on the solenoid valve may detach and fail due to excessive vibration frequency, thus affecting the valve's operation. Utility Model Content

[0004] The purpose of this invention is to provide a PIN pin connection structure for solenoid valves to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a PIN pin connection structure for a solenoid valve, comprising a circuit board, wherein the circuit board is connected to the PIN pin by soldering, a solenoid valve coil frame is provided below the PIN pin, a PIN pin mounting groove is provided on the upper surface of the solenoid valve coil frame, and the lower end of the PIN pin is inserted into the PIN pin mounting groove.

[0006] Preferably, the pin has a corrugated structure at the end of the pin, a V-shaped solder pad in the middle of the pin, and a snap-fit ​​is formed between the protrusions of the corrugated structure.

[0007] Preferably, the V-shaped solder pads are welded to the copper wires, and the corrugated structure is coated with adhesive.

[0008] Compared with the prior art, the beneficial effects of this utility model are: the PIN pin is designed with a V-shaped solder piece for resistance welding, and the connection between the solenoid valve PIN pin and the copper wire is realized by resistance welding, which simplifies the process compared with soldering; the solenoid valve PIN pin foot adopts a corrugated structure, and a snap-fit ​​connection is used when connecting with the coil frame, which increases the connection reliability; in addition, glue can be applied during connection, which increases the connection reliability and improves the pull-out strength.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0014] Please refer to 1-3. One embodiment of this utility model is provided: a PIN pin connection structure for a solenoid valve, including a circuit board 1. The circuit board 1 is connected to a PIN pin 2 by soldering. A solenoid valve coil frame 3 is provided below the PIN pin 2. A PIN pin mounting groove is provided on the upper surface of the solenoid valve coil frame 3. The lower end of the PIN pin 2 is inserted into the PIN pin mounting groove. The upper end of the PIN pin 2 is connected to the circuit board 1 by soldering, and the lower end is inserted into the solenoid valve coil frame 3. The corrugated structure 21 at the end of the pin of the PIN pin 2 forms a snap-fit ​​with the solenoid valve coil frame 3, increasing the reliability of the connection.

[0015] The pin 2 has a corrugated structure 21 at the end of the pin. The corrugated structure 21 is made by stamping to form a corrugated shape with high and low undulations. The pin 2 has a V-shaped solder piece 22 in the middle. The solenoid valve pin 2 is connected to the copper wire by resistance welding. The resistance welding connection method is simpler than soldering. The protrusions of the corrugated structure 21 form a snap-fit, and the high and low undulations of the corrugated shape form a snap-fit ​​connection with the pin mounting groove, making the connection more reliable and stable.

[0016] V-shaped solder pads 22 are used to weld and connect copper wires, and the corrugated structure 21 is coated with adhesive, which increases the reliability of the connection and improves the pull-out strength.
