Abstract: A method for assembling an ultrahigh-frequency spring probe test assembly includes: drilling signal cavities, power supply cavities, and grounding cavities, assembling an upper mold core and a lower mold core and performing curing, mounting an upper shaft sleeve and a lower shaft sleeve, inserting a signal probe, a power supply probe and a grounding probe, and mounting an upper base to complete assembling the probe test assembly. The signal probe becomes coaxial with the signal cavity by mounting the insulating ring, achieving small signal loss; the insulating mold core is inserted into the power supply cavity after drilling and is bonded to the power supply cavity via adhesive to form a dual-layer insulating structure between the power supply probe and the base, having high insulation performance and low power loss; the grounding probe is in direct contact with the metal base, achieving high conductivity.

Abstract: A side punching mechanism with a movable guide block includes a slider base disposed in a lower die. A slider is disposed on the slider base, a side punching pin is disposed at a front end of the slider, a movable guide block connected to the slider base in a sliding fit manner is disposed in front of the slider, the movable guide block includes a concave movable base and a boss disposed on the movable base, a front end of the boss protrudes forwards and extends out from the movable base, the front end of the boss has a shape of an indented arc, the boss is disposed at the center of the movable base, a through-hole is formed in the boss, and the slider slides on the slider base along a concave space of the movable base to drive the side punching pin to move in the through-hole.

Abstract: The application provides a spring probe with high stability, which comprises a hollow syringe with a spring in it. The upper end and the lower end of the syringe has an upper thimble and a lower thimble respectively. There are two support rings at the outer clearance of the syringe, and a group of flanges for positioning the support rings at two sides of each support ring. The advantages of this application are that: the support ring can ensure that the spring probe is better fixed in the fixed plate without being pressed out, thereby better ensuring that the spring probe does not deviate beyond the tolerance range when used, and obviously improving the high frequency bandwidth by the support ring with low relative dielectric constant.

Abstract: The invention provides a high-frequency pawl spring probe applied to 5G, which comprises a sleeve with a hollow cavity inside with a spring in it. There is a pawl spring at the upper end in the sleeve; the pawl spring comprises a cylindrical pawl spring cylinder and the elastic sheets at the lower end of the pawl spring cylinder; and the pawl spring cylinder is in an interference fit with the sleeve. A plunger is set in the pawl spring, and the elastic sheets are in contact with the plunger. The advantages of this invention are that: the probe structure has good directivity with small fluctuation of resistance value, which can be used in vibration or under the fluctuating external force, thus avoiding the instantaneously cut-off of the probes at present. The application range is expanded, which well meets the requirements of the equipment reliability in the 5G era.
