SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, the utility model provides a multi-functional universal fixture of PCBA.
In order to improve the working efficiency of a laboratory, save the cost of an enterprise and the cost expenditure of a client and shorten the period, the PCBA clamp is developed to meet the test requirement, so that the efficiency is improved and the cost is reduced. The utility model provides a following technical scheme: a PCBA multi-function universal fixture, comprising: the thread die comprises a base, a nut, an upright post and a thread sleeve, wherein thread holes are formed in two ends of the base, an integrated thread sleeve is embedded in each thread hole, the upright post is connected with the thread sleeve in an internal thread mode, the upright post can spirally lift along the inside of the thread sleeve, the nut is sleeved on the outer side of the thread sleeve in a threaded mode, and the nut can rotate along the outer side of the thread sleeve to lock the upright post; the stand top is equipped with the screw hole that is used for connecting PCBA.
The middle part of the base is provided with a hollowed-out groove, and the hollowed-out groove can be fixed on the test table board through screws.
The upright column is a conical support column, the upper opening is small, and the lower opening is large.
The upright posts are made of non-metal PEEK materials or coated nylon materials.
The tooth socket is made of steel materials.
The length of the base is the same as the size of the test table top, and the central opening is provided with an oval opening according to 3/5 of the distance between the test table top holes.
The utility model discloses the beneficial effect who brings is:
the utility model adjusts the heights of the upright posts at two sides by rotating the upright posts, thereby realizing the clamping aiming at PCBAs with different height specifications, and simultaneously adopting the nuts to lock the upright posts, thereby preventing the conditions of looseness and the like in the test process; the upright posts can be made of non-metallic materials, so that electric performance interference such as short circuit is avoided; in addition, the connection part of the upright post and the base is connected by a steel tooth socket, so that the fixing strength is improved, the cost is low, and the service life is prolonged.
