Description

Technical Field

[0001] The utility model belongs to the technical field of connectors, and particularly relates to a connector positioning device structure. Background Art

[0002] As the technology of autonomous driving continues to improve, the requirements for connector stability are becoming higher and higher. Ordinary automotive connectors have a self-locking feature that allows the male and female connectors to be fixed to each other when mated. They will not loosen when subjected to small external forces or vibrations, but when the connector is pulled by a large external force or subjected to large vibrations, the self-locking feature will fail and the electrical signal transmission of the connector will be interrupted, which is very dangerous for autonomous vehicles on the road.

[0003] The common locking devices on the market are usually inserted from the tail of the female plastic body. When the connector needs to be unlocked, the locking device can be pulled a certain distance toward the tail to unlock it. However, since it is a structure that is installed from the back to the front, this structure has the following disadvantages: 1. After the locking device is assembled with the female plastic body, the limit is insufficient, and there is a risk of warping and derailing during transportation or sliding; 2. The locking device is easily triggered by mistake before being inserted into the male plastic body, resulting in the lock hook being unable to be inserted normally; 3. After the lock hook is locked, it is difficult to pull back the locking device, resulting in difficulty in unlocking. Therefore, there is an urgent need for a connector positioning device structure that is stable in assembly, not easily triggered by mistake, and easy to unlock to solve the deficiencies in the prior art. Utility Model Content

[0004] The purpose of the utility model is to provide a connector positioning device structure to solve the deficiencies in the prior art.

[0005] In order to achieve the above utility model purpose, the technical solution adopted by the utility model is:

[0006] A connector positioning device structure comprises: a male end plastic body, a female end plastic body and a locking piece, wherein a locking hook is arranged at one end of the male end plastic body, a locking groove matched with the locking hook is arranged at one end of the female end plastic body, a vertical limiting groove is arranged at the top of the female end plastic body, and the locking piece is slidably arranged in the vertical limiting groove.

[0007] Preferably, the locking member comprises: a main body, a through slot is provided in the middle of the main body, a locking step is provided at the rear end of the through slot, an anti-accidental touch spring arm is provided in the middle of the front end of the main body, and limiting guard arms are provided on both sides of the anti-accidental touch spring arm.

[0008] Preferably, a protective cover is provided above the anti-mis-touch elastic arm.

[0009] Preferably, a protrusion structure is provided at the front end of the anti-mistake-touch elastic arm.

[0011] Preferably, the distal ends of the two limiting guard arms are each provided with a third limiting boss, and the front end of the vertical limiting groove is transitioned to a transverse limiting groove matched with the third limiting boss.

[0012] Preferably, a pressing component is arranged in the vertical limiting groove, the locking piece is sleeved on the peripheral side of the pressing component, and the locking groove is opened at the front end of the pressing component.

[0013] Preferably, an anti-slip groove is provided on the bottom wall of the vertical limiting groove, and a sliding block slidably matched with the anti-slip groove is provided at the bottom end of the locking member.

[0014] Preferably, an avoidance groove is further provided below the lock groove, and the avoidance groove is used to avoid the lock hook.

[0015] The connector positioning device structure provided by the utility model has the following advantages compared with the prior art:

[0016] 1. The vertical limiting groove cooperates with the first limiting boss and the second limiting boss to realize the vertical limiting of the locking member, and the horizontal limiting groove cooperates with the third limiting boss, the anti-slip groove and the slider to realize the horizontal limiting of the locking member, thereby avoiding the problem of the locking member warping up and derailing during transportation or sliding, and improving the stability of the connector assembly;

[0017] 2. By providing a protective cover above the anti-mis-trigger spring arm, the locking element can be effectively prevented from being accidentally triggered before being inserted into the male end plastic body;

[0018] 3. The elasticity of the limit guard arm can be used to easily release the lateral restriction of the locking piece, making it easier to unlock and improving the user experience. The anti-slip groove effectively avoids the phenomenon of the locking piece being detached due to excessive pulling force, and is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS
