Description

Universal clamp structure for clamping small probe card
Technical Field
The utility model relates to an electronic equipment's technical field specifically is a universal fixturing structure of small-size probe card clamping.
Background
In the probe card manufacturing process, the accent needle post needs fixed PCB to adjust the needle point position, we need fix PCB to on the dedicated anchor clamps, with the screw hole on the hole alignment anchor clamps on the PCB, use the bolt fastening, this anchor clamps correspond the PCB that various models differ in size and have the limitation relatively, be fixed unchangeably with the interval because of its fixed screw hole size, can only use with the cooperation of the same model PCB, can't adjust in a flexible way to the PCB locating hole specification of a great variety, anchor clamps kind too leads to the cost of manufacture to rise, the shortcoming such as management difficulty is but.
SUMMERY OF THE UTILITY MODEL
In order to improve the problem in the above-mentioned background art, the utility model provides a universal fixturing structure of small-size probe card clamping.
The utility model adopts the following technical proposal:
a universal clamp structure for clamping a small probe card comprises: comprises a plurality of aluminum base frames and a plurality of movable blocks; the utility model discloses a clamp C type skeleton, including aluminium bed frame, anchor clamps C type skeleton, movable mounting has a plurality ofly in the anchor clamps C type skeleton the movable block, the movable block up end all opens threaded hole, the height of movable block is less than the height of anchor clamps C type skeleton.
By adopting the technical scheme, a plurality of types of clamps can be replaced by one type, the size of the threaded hole can be freely selected, the distance between the threaded holes can be flexibly adjusted, the universal use of the clamp can be realized by corresponding to different PCBs, the problem that the manufacturing cost of a company caused by a plurality of clamps is increased in the past is solved, the clamp is simple and practical, and the warehousing removal of the plurality of types of clamps is realized.
Furthermore, the cross section of the movable block is T-shaped.
By adopting the technical scheme, the movable block is movably connected with the C-shaped fixing frame of the clamp through the T-shaped movable block, so that the movement is limited.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses simple structure, the commonality is strong, can a section replace many kinds of anchor clamps, but screw hole size free choice, and the screw hole interval can be adjusted in a flexible way, and it is general all can to realize an anchor clamps to correspond different PCB, and the company cost of manufacture that solves many calories of multi-anchor clamps and lead to in the past rises, and simple and practical realizes that many kinds of anchor clamps remove the warehousing.
The present invention will be explained in detail with reference to the drawings and specific embodiments.
Drawings
FIG. 1 is a schematic view of a conventional clamping structure of a small probe card;
FIG. 2 is a cross-sectional view of the overall structure of the present invention;
fig. 3 is a schematic view of the installation of the movable block of the present invention.
In the figure: 1. an aluminum base frame; 2. a movable block; 3. a threaded hole; 4. the fixture is a C-shaped framework.
Detailed Description
In order to facilitate understanding of the present invention, the present invention will be described more fully with reference to the accompanying drawings, in which several embodiments of the present invention are shown, but the present invention can be implemented in different forms, and is not limited to the embodiments described in the text, but rather, these embodiments are provided to make the disclosure of the present invention more thorough and comprehensive.
It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may be present, and when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present, as the terms "vertical", "horizontal", "left", "right" and the like are used herein for descriptive purposes only.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs, and the terms used herein in the specification of the present invention are for the purpose of describing particular embodiments only and are not intended to limit the present invention, and the term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.
The first embodiment is as follows:
with reference to fig. 1-3, a universal fixture structure for clamping a small probe card is characterized in that: comprises a plurality of aluminum base frames 1 and a plurality of movable blocks 2; anchor clamps C type skeleton 4 is installed to 1 upper end of aluminium bed frame, movable mounting has a plurality ofly in anchor clamps C type skeleton 4 the movable block 2, threaded hole 3 has all been opened to 2 up end of movable block, highly being less than of movable block 2 anchor clamps C type skeleton 4's height.
Please refer to fig. 2 and fig. 3, the cross section of the movable block 2 is T-shaped.
The embodiment of the utility model provides a general anchor clamps structure of small-size probe card clamping implement the principle and do:
according to the PCB mounting hole, the movable block 2 with the size of the threaded hole 3 corresponding to the mounting hole is selected, the C-shaped framework 4 of the clamp is installed, the movable block 2 is moved, the distance between the threaded hole 3 can be flexibly adjusted, the threaded hole 3 corresponds to the mounting hole, the PCB is installed, and the universal clamp structure can be realized by corresponding to different PCBs.
The present invention has been described above with reference to the accompanying drawings, and it is obvious that the present invention is not limited by the above-mentioned manner, if the method and the technical solution of the present invention are adopted, the present invention can be directly applied to other occasions without substantial improvement, and the present invention is within the protection scope of the present invention.
