Technical Field
The utility model belongs to the technical field of automobiles, and particularly relates to a stay wire distributor for an automobile door lock.
Background
In the field of automobile opening and closing parts, a typical application scenario is that when two door locks (L1, L2) are required to be configured for one opening and closing body (for example, a vehicle door, a front hatch, a trunk lid, etc.), the two door locks are required to work synchronously, i.e., to unlock and close the door synchronously or to self-suction and close the door synchronously. Two door locks on the opening and closing body are necessarily arranged at a relatively far position due to the function realization of the opening and closing body and the consideration of the overall strength. Based on the cost, the two are usually connected by using a pull rope, and the same driving operation mechanism A can be used for executing the synchronous work manually or electrically to realize the function of an opening and closing body.
