Embodiment Construction

[0022] In order to describe the content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in combination with the embodiments and accompanying drawings.

[0023] In the description of the present invention, it should be understood that the orientations or positional relationships indicated by the terms "inner", "outer", "upper", "lower", "top", "bottom" etc. are based on those shown in the accompanying drawings. The orientation or positional relationship is only for the convenience and simplification of the description of the present invention, and thus cannot be construed as limiting the protection content of the present invention.

[0024] The present invention discloses a fixing device 100, which is used for fixing an object 300, and is especially suitable for fixing a magnetic field generator, so as to ensure that the position of the magnetic field generator will not be displaced. Hereinafter, the...

Abstract

The invention discloses a fixing device. The fixing device comprises a base, wherein the base comprises an elastic tube body; the tube body defines an accommodating space for accommodating an article;a position limiting element is arranged at the outer side of the tube body; the position limiting element is arranged on the outer periphery of the tube body in a surrounding way and forms a gap withthe tube body; a plurality of elastic elements are arranged in the gap; the plurality of elastic elements are uniformly distributed in the circumferential direction of the tube body; the article is placed in an accommodating space; the tube body outwards expands through being extruded by the article; at the moment, the tube body outwards jacks the elastic elements; and meanwhile, the elastic elements can inwards prop the tube body through being blocked by the position limiting element. Through the plurality of elastic elements, uniform and inward acting force is applied to the tube body, so that the occurrence of position deviation of the article is avoided; and the stable fixation of the article is realized. In addition, when the article needs to be mounted or dismounted, the article canbe placed into the accommodating space or can be pulled out; and the mounting and the dismounting of the article are simple and fast. In addition, the tube body is elastic, so that the applicabilityto an article with certain dimension deviation can be realized. In addition, the invention also discloses a chip test probe card.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a fixing device and a chip test probe card with the fixing device. Background technique [0002] In the industrial field, in order to ensure the smooth progress of the operation, the problem of fixing objects is often involved. Especially in the chip test line of the magnetic sensor, it is necessary to stably fix the magnetic field generator on the probe card to ensure that the coil axis of the magnetic field generator is always perpendicular to the chip center of the magnetic sensor, thereby ensuring that the magnetic field generator can A constant magnetic flux is generated to meet the requirements for a uniform magnetic field during chip testing, thereby ensuring the precision and accuracy of chip testing. [0003] At present, the magnetic field generator is fixed on the probe card mainly by setting a fixing device on the probe card. However, due to production a...
