[0029] Reference example Figures 1 to 8An anti-loosening electronic wire harness includes a connector 1 and terminals 2. The connector 1 has several equally spaced chambers 11 for accommodating the terminals 2. Each chamber 11 has a retaining part 12 and a retaining groove 13 on both sides. The retaining part 12 is located near the entrance of the chamber 11. Each chamber 11 has a clearance groove 14. The retaining groove 13 is located between the retaining part 12 and the clearance groove 14. The terminal 2 has a first through hole 21 that abuts against the retaining part 12. The connector 1 has a fixing member 3 that passes through the terminal 2 and is inserted into the retaining groove 13. The terminal 2 has a spring-loaded... The first elastic part 22 is disposed in the relief groove 14. The anti-retraction part 12 abuts against the first through hole 21 to form a first locking point. The first elastic part 22 is disposed in the relief groove 14 to form a second locking point. The fixing member 3 passes through the terminal 2 and is inserted into the relief groove 14. The relief groove 14 and the connector 1 itself provide stable support for the fixing member 3, forming a third locking point. The multiple locking points work together to effectively prevent the terminal 2 from dislodging from the chamber 11 when the wire 4 is affected by external force or vibration, ensuring that the terminal 2 and the connector 1 maintain a stable connection.
[0030] It is worth mentioning that the fastener 3 has a fastening part 31 on both sides and a protrusion 32 on both sides. The fastener 3 is connected and fixed to the groove 15 by the protrusion 32 in an interference fit. The fastening part 31 passes through the second through hole 28 and is inserted into the relief groove 14. The relief groove 14 and the through hole 151 together provide a support structure for the fastening part 31. This structural design enables the fastening part 31 to effectively restrict the position of the terminal 2 and prevent the terminal 2 from detaching from the connector 1 cavity 11.
[0031] It is worth mentioning that the connector 1 is provided with a recess 15 for accommodating the fixing member 3, so that the fixing member 3 is flush with the surface of the connector 1, and the two sides of the recess 15 are provided with through holes 151 for the fixing part 31 to pass through.
[0032] It is worth mentioning that the chamber 11 is provided with a socket 16, and the relief groove 14 is located near the socket 16. The bottom of the chamber 11 is provided with a relief groove 17 for the first elastic part 22 to move and communicates with the relief groove 14. The socket 16 is provided to accommodate the pin of the male connector 1. The relief groove 17 is designed to prevent the first elastic part 22 from being excessively deformed under pressure when it enters the chamber 11, so as to avoid it losing its elastic force. When the first elastic part 22 enters the relief groove 14, the first elastic part 22 releases its elasticity and enters the relief groove 14.
[0033] It is worth mentioning that the terminal 2 has a first locking part 23 and a second tightening part that are curled towards the middle on both sides for fixing the wire 4 and the exposed part of the wire 4. The first locking part 23 is used to embed the insulation layer of the wire 4 and press the wire 4 onto the terminal 2. The second locking part 24 presses the exposed part of the wire 4 onto the terminal 2 to prevent the wire 4 from falling off the terminal 2.
[0034] It is worth mentioning that the terminal 2 has a bent first pressure bearing portion 25 and a second pressure bearing portion 26 on both sides, and a second elastic portion 27 at one end of the terminal 2, which applies an upward force. The second elastic portion 27 is located below the first pressure bearing portion 25 and the second pressure bearing portion 26. When the pin enters between the second elastic portion 27 and the first pressure bearing portion 25 and the second pressure bearing portion 26, the second elastic portion 27 applies an upward force to the pin, making the pin fit tightly with the first pressure bearing portion 25 and the second pressure bearing portion 26, ensuring a stable connection.
[0035] It is worth mentioning that the terminal 2 is provided with a second through hole 28 through which the fixing part 31 passes;
[0036] It is worth mentioning that the anti-retraction part 12 is provided with an inclined surface 121 facing the entrance of the chamber 11, and the inclined surface 121 facilitates the smooth entry of the terminal 2 into the chamber 11.
