Technical Field

[0001] This utility model relates to the field of chip testing technology, and in particular to a chip testing socket with an adjustable dial. Background Technology

[0002] Packaging testing is the process of verifying the structure and electrical function of a semiconductor component after it has been packaged, ensuring that the component meets system requirements. Test sockets are essential consumables in semiconductor packaging testing. They play a crucial role in connecting the chip under test to the motherboard for electrical signal transmission.

[0003] However, for traditional equipment, the pressure stroke of the traditional test socket is fixed, and the pressure block needs to be individually adapted according to each thickness of chip. This results in high manufacturing costs, inconvenience in replacement, and difficulty in meeting the diverse needs of customers, thus requiring improvement. Utility Model Content

[0004] The purpose of this utility model is to solve the technical problems mentioned in the background art.

[0005] This utility model adopts the following technical solution: a chip test socket with a conveniently adjustable dial, including a fixed base, with limit rods fixedly installed on both sides of the fixed base. A buckle is sleeved on the outer surface of the limit rod, and a spring is fixedly installed at one end of each buckle. A groove is formed at the bottom of the fixed base, and a pressure block is sleeved inside the groove. A stepped bolt is threaded into the groove, and a spring is sleeved on the outer surface of the stepped bolt. A through groove is formed at the top of the fixed base, with a threaded first thread inside the through groove. A screw shaft is sleeved inside the through groove. A positioning groove is formed at the top of the fixed base. The screw shaft has an internal threaded connection with a positioning bolt, and a positioning block is fixedly installed at the top of the positioning bolt. A scale is fitted on the outer surface of the screw shaft. A limit groove is formed at the bottom of the scale, and an adjustment groove is formed at the top of the scale. A knob is set at the top of the scale, and a pressing groove is formed on the surface of the knob. A limit bolt is connected to the internal thread of the pressing groove. A button is fitted inside the pressing groove, and a fixing rod is fixedly installed on the surface of the button. A spring is fitted inside the pressing groove. An insertion groove is formed through the surface of the knob, and a fixing bolt is inserted into the insertion groove. A fixing screw groove is formed at the top of the screw shaft.

[0006] Preferably, the number of fixing screw grooves is multiple and they are circumferentially distributed on the surface of the screw shaft. The screw shaft and the through groove are connected by a thread. Here, the multiple sets of circumferentially distributed fixing screw grooves increase the flexibility and adjustability of the connection between the knob and the screw shaft. Appropriate fixing screw grooves can be selected for connection according to actual needs, so that the knob can reliably drive the screw shaft to rotate.

[0007] Preferably, the number of insertion slots and fixing bolts is four sets, which are circumferentially distributed inside the knob and screw shaft. The insertion slots are arc-shaped ellipses and penetrate the knob. Here, the four sets of circumferentially distributed insertion slots and fixing bolts make the connection between the knob and screw shaft more secure and stable, and the evenly distributed connection points can better transmit torque and prevent loosening.

[0008] Preferably, one end of the spring three is connected and fixed to the rear end of the button, and the other end of the spring three is connected and fixed to the inner surface of the pressing groove. The bottom end of the fixing rod is sleeved inside the adjusting groove. Here, one end of the spring three is connected to the button, and the other end is connected to the inner surface of the pressing groove, providing the button with a resetting elastic force.

[0009] Preferably, the other end of the first spring is connected and fixed to the surface of the fixed base. There are two sets of the first springs, symmetrically distributed at the rear end of the buckle. Similarly, there are two sets of buckles, symmetrically distributed on the surface of the fixed base. Here, the two symmetrically distributed springs, one end connected to the buckle and the other end connected to the fixed base, provide elastic tension to the buckle, allowing it to tightly fasten onto the limiting rod, thus effectively limiting and locking the fixed base.

[0010] Preferably, the number of the second spring and the stepped bolts is four sets, symmetrically distributed around the fixing seat and the pressure block. One end of the second spring is connected and fixed to the top surface of the stepped bolt, and the other end of the second spring is connected and fixed to the bottom end of the pressure block. Here, the symmetrical distribution can evenly distribute the pressure, prevent the components from loosening or shifting during operation, improve the reliability and service life of the chip test socket, and ensure the accuracy and stability of the testing process.

[0011] Preferably, the stepped bolt and the groove are threadedly connected, the stepped bolt is sleeved inside the pressure block, and the fixing bolt is threadedly connected to the fixing groove. Here, the stepped bolt is threadedly connected to the groove and sleeved inside the pressure block. This connection method allows the pressure block to be stably installed on the fixed seat. The clamping degree of the pressure block can be adjusted by tightening the stepped bolt to adapt to different installation requirements.

[0012] Preferably, the limiting groove is an arc-shaped ellipse, and the angle of the limiting groove and the angle of the dial are both 180 degrees. The positioning block is fitted inside the limiting groove, and there are three sets of positioning grooves distributed circumferentially at the top of the fixed base. Here, the arc-shaped ellipse limiting groove with an angle of 180 degrees, in conjunction with the positioning block, can better position and limit the dial, ensuring the accuracy and stability of the dial's rotation.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] In this invention, by setting up a fixed base, a limiting rod, a buckle, a first spring, a groove, a pressure block, a stepped bolt, a second spring, a through groove, a first thread, a screw shaft, and a positioning groove, multiple structures work together to fix chips of different thicknesses during use, facilitating testing. Furthermore, the locking and unlocking mechanisms of the dial have been redesigned and are located at the top of the test socket to avoid interference with electronic components. The coaxial structure eliminates torque, ensuring smooth operation. Attached Figure Description
