[0001] The utility model provides a test socket for a radar induction chip, which relates to the technical field of radar induction chip testing. Background Art

[0002] A test socket for a radar induction chip is a device specifically designed to test integrated circuit chips with radar induction functions. It is a key tool for functional verification, performance evaluation, and quality control of chips with radar induction technology, and plays an important role in product development and production testing in fields such as smart home, security monitoring, and automatic control.

[0003] After the existing test socket finishes testing the radar induction chip, it is necessary to use tweezers to take out the chip from the placement groove of the test socket. However, this method is rather troublesome, and when using tweezers to pick up the chip, it is easy to scratch the chip, resulting in chip failure.

[0004] Therefore, it is necessary to provide a test socket for a radar induction chip that is convenient for taking out the chip. Summary of the Utility Model

[0005] In order to overcome the drawback that after the existing radar induction chip is tested, it is necessary to use tweezers to remove the chip, and it is easy to scratch the chip when using tweezers, resulting in chip failure, the utility model provides a test socket for a radar induction chip that is convenient for taking out the chip.

[0006] In order to achieve the above purpose, the embodiment of the utility model provides the following technical solution: A test socket for a radar induction chip includes a base, a connecting wire, a connecting rod, and a cover plate. A connecting rod is fixedly connected to the base, and a cover plate is rotatably arranged on the connecting rod. A plurality of connecting wires are fixedly connected to the bottom of the base. It further includes a support plate, a first guiding rod, a mounting rack, an electromagnet, a first elastic member, and a lifting plate. A support plate is installed on the base, two first guiding rods are fixedly connected to the support plate, a mounting rack is slidably arranged on the two first guiding rods together, a lifting plate is installed on the mounting rack, electromagnets are fixedly connected to both sides of the mounting rack and the base, and a first elastic member is fixedly connected between two electromagnets on the same side.

[0007] Further, the lifting plate is made of insulating material.

[0008] Further, it further includes a latch installed on one side of the cover plate. An installation shell is installed on one side of the base. A latch rod is slidably arranged on both sides of the installation shell. A second elastic member is wound around the latch rod, and the second elastic member pushes the latch rod to be clamped with the latch.

[0009] Further, one side of the latch rod is a wedge-shaped surface.

[0010] Furthermore, it also includes two second guide rods fixedly connected to the bottom of the cover plate, a pressure plate is slidably arranged on the two second guide rods, and a third elastic member is fixedly connected between the pressure plate and the cover plate.

[0011] Furthermore, it also includes a protection plate arranged at the bottom of the base, and a plurality of screws are threadedly connected to the protection plate and the base, and nuts are threadedly arranged on the screws.

[0012] Furthermore, an antistatic mat is installed on the edge of the chip placement slot of the base.

[0013] Furthermore, a fourth elastic member is fixedly connected inside the mounting shell.

[0014] Compared with the prior art, the test socket provided by the embodiment of the utility model has the following advantages: 1. By energizing the electromagnet, the upper and lower electromagnets attract each other. At this time, the mounting frame drives the lifting plate to slide upward along the two first guide rods, and then the lifting plate pushes out and lifts the radar sensor chip, thereby achieving the effect of facilitating the removal of the radar sensor chip.

[0015] 2. By covering the cover plate on the base, the card block is inserted into the mounting shell, and the second elastic member pushes the card rods on both sides to clamp the card block together under the force, so that the cover plate cannot be rotated to open, thereby achieving the effect of fixing the cover plate on the base and preventing the cover plate from opening during testing.

[0016] 3. By putting the cover down, the pressure plate presses the radar sensor chip under the force of the third elastic member, so that the radar sensor chip will not shake on the base, and the data during testing will be more accurate and reliable, thereby achieving the effect of fixing the radar sensor chip.

[0017] 4. Install the protection plate on the bottom of the base through the cooperation of the screw and the nut. The protection plate can protect the connecting wires at the bottom of the base to prevent the connecting wires from being crushed and damaged. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0026] The present utility model will be specifically described below with reference to the accompanying drawings.

[0027] Embodiment 1: A radar induction chip test socket. Refer to Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, it includes a base 1, a connecting wire 101, a connecting rod 2 and a cover plate 3. A connecting rod 2 is fixedly connected to the base 1, and a cover plate 3 is rotatably arranged on the connecting rod 2. Four connecting wires 101 are fixedly connected to the bottom of the base 1 by welding. It further includes a support plate 4, a first guide rod 401, a mounting frame 5, an electromagnet 501, a first elastic member 502 and a lifting plate 6. The support plate 4 is installed on the base 1 by bolt connection, and two first guide rods 401 are fixedly connected to the support plate 4 by welding. A mounting frame 5 is slidably arranged up and down on the two first guide rods 401 together. A lifting plate 6 for ejecting the radar induction chip is installed on the top of the mounting frame 5 by welding. The lifting plate 6 is made of insulating material to avoid electric shock injury during chip testing. Electromagnets 501 are fixedly connected to both sides of the mounting frame 5 and the base 1, and a first elastic member 502 is fixedly connected by welding between the two electromagnets 501 on the same side.

[0028] When it is necessary to test the radar induction chip, rotate the cover plate 3 along the connecting rod 2 to open it, then place the radar induction chip in the placement groove of the base 1. Subsequently, rotate the cover plate 3 to cover it, and install the base 1 on the PCB board for testing. After the test is completed, rotate the cover plate 3 to open it, then energize the electromagnet 501. The upper and lower electromagnets 501 attract each other. At this time, the mounting bracket 5 drives the lifting plate 6 to slide upward along the two first guide rods 401. At this time, the first elastic member 502 is compressed and deformed, so that the lifting plate 6 pushes the radar induction chip out and rises, facilitating the removal of the radar induction chip. When the power supply to the electromagnet 501 is stopped, the first elastic member 502 pushes the mounting bracket 5 to slide downward and reset.

[0029] Embodiment 2: On the basis of Embodiment 1, refer to Figure 4 and Figure 5 As shown, it further includes a clamping block 7 installed on the side of the cover plate 3 away from the connecting rod 2 by means of bolt connection. On one side of the base 1, a mounting shell 8 is installed by means of bolt connection. On both sides of the mounting shell 8, clamping rods 9 are arranged in a horizontal sliding manner. One side of the clamping rod 9 is a wedge surface, so that when the clamping block 7 is inserted into the mounting shell 8, the clamping rods 9 on both sides are pushed away from each other along the wedge surface. A second elastic member 901 is wound around the clamping rod 9, and the second elastic member 901 pushes the clamping rod 9 to be clamped with the clamping block 7.

[0030] When the cover plate 3 is covered on the base 1, the clamping block 7 is inserted into the mounting shell 8, and the clamping block 7 pushes the clamping rod 9 to slide away from the mounting shell 8. At this time, the second elastic member 901 is compressed and deformed. After the clamping block 7 is completely inserted into the mounting shell 8, the second elastic member 901 pushes the clamping rod 9 to slide back to its original position. At this time, the clamping rod 9 clamps the clamping block 7, and the cover plate 3 cannot be rotated and opened; when it is necessary to rotate and open the cover plate 3, first pull the two clamping rods 9 on the mounting shell 8 away from each other, so that the clamping rod 9 is disengaged from the clamping block 7, and then rotate the cover plate 3 to open it.

[0031] Refer to Figure 6 As shown, it further includes two second guide rods 10 fixedly connected to the bottom of the cover plate 3 by welding. A pressing plate 11 for pressing the radar induction chip is slidably arranged on the two second guide rods 10 together. A third elastic member 12 is fixedly connected between the pressing plate 11 and the cover plate 3.

[0032] After the radar induction chip is placed in the placement groove of the base 1, when the cover plate 3 is covered, the pressing plate 11 presses the radar induction chip under the action of the third elastic member 12, so that the radar induction chip does not shake on the base 1, and the data during the test is more accurate and reliable. If the radar induction chip is relatively thick, when the cover plate 3 is covered, the pressing plate 11 slides close to the cover plate 3 along the second guide rod 10. At this time, the third elastic member 12 is compressed and deformed. When the cover plate 3 is rotated and opened, the third elastic member 12 pushes the pressing plate 11 to slide back to its original position.

[0033] Refer to Figure 7 As shown, it further includes a protection plate 13 arranged at the bottom of the base 1. A plurality of screw rods 14 are commonly connected to the protection plate 13 and the base 1 in a threaded manner, and nuts 15 are arranged on the screw rods 14 in a threaded manner.

[0034] When transporting the test seat, the connecting wire 101 is easily crushed and broken. At this time, the protection plate 13 is installed at the bottom of the base 1 through the cooperation of the screw rod 14 and the nut 15, and the connecting wire 101 at the bottom of the base 1 is protected by the protection plate 13 to avoid the connecting wire 101 from being crushed. When it is necessary to connect the connecting wire 101 to the PCB board for testing, the screw rod 14 and the nut 15 are disassembled to expose the connecting wire and connect it to the PCB board.

[0035] Refer to Figure 5 and Figure 6 As shown, an anti-static table mat 16 is installed at the edge of the chip placement groove of the base 1 by bonding; a fourth elastic member 17 is fixedly connected inside the installation shell 8 by welding.

[0036] The anti-static table mat 16 can prevent static electricity conduction between the radar induction chip and the base 1 to avoid abnormal circuits; when the block 7 is inserted into the installation shell 8, the fourth elastic member 17 will be compressed and deformed, and after the lever 9 is pulled away, the fourth elastic member 17 can eject the block 7 out of the installation shell 8 to facilitate the opening and closing of the cover plate 3.

[0037] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
