Description

[Technical Field]

[0001] This invention relates to a chip connector, and more particularly to a chip connector having a locking mechanism. [Background Technology]

[0002] Chinese Utility Model Patent No. CN202712640U discloses a chip connector for electrically connecting a chip module. It includes a base and conductive terminals held in the base. The base defines an upper surface supporting the chip module, a lower surface opposite to the upper surface, and several terminal slots penetrating both surfaces. The conductive terminals are received in the terminal slots and partially protrude from the upper surface. The base has a positioning block for fixing the chip module and a positioning member for fixing the positioning block to the upper surface on the upper surface. The positioning member is fitted onto the positioning block and extends a locking arm. The locking arm is locked against the lower surface via the terminal slots to fix the positioning member. The positioning member also has an unlocking part for releasing the locking arm. This chip connector can test chip modules of different geometric sizes. This chip connector uses conventional positioning blocks to secure the chip module.

[0003] Therefore, it is indeed necessary to provide an improved chip connector to overcome the above-mentioned defects. [Summary of the Invention]

[0004] The technical problem to be solved by the present invention is to provide a chip connector with a locking mechanism.

[0005] The present invention is achieved through the following technical solution: a chip connector, comprising a body carrying terminals, a limiting seat forming a receiving cavity around the body, and a locking mechanism, wherein the receiving cavity is used to receive a chip, the receiving cavity is open upward and has multiple inner wall surfaces; the locking mechanism includes an operating part and a fixing part; the operating part drives the fixing part to apply force to the chip to fix the chip in the chip receiving cavity, or releases the fixing part from fixing the chip.

[0006] Furthermore, the chip is assembled into the receiving cavity from top to bottom, while the fixing part enters the receiving cavity in a transverse direction perpendicular to the vertical direction.

[0007] Furthermore, the fixing part passes through the inner wall surface and can be pressed tightly against the side of the chip.

[0008] Furthermore, the locking mechanism also includes a spring that elastically presses against the fixing part to increase the force exerted by the fixing part on the chip.

[0009] Furthermore, the limiting seat includes multiple sidewalls, one of which has a through hole. The locking mechanism includes a moving block and an operating rod. The operating rod includes a cam portion. The inner end of the moving block forms the fixing portion, and the opposite outer end passes through the through hole to form a connecting portion. The connecting portion and the cam portion are connected to each other through a pivot shaft. The cam portion abuts against the outer wall surface of the sidewall and has a different radius. The operating portion rotates, causing the cam portion to rotate, thereby driving the moving block to move away from or towards the receiving cavity.

[0010] Furthermore, the spring is disposed between the fixing part and the inner wall surface of the side wall, and is preset to elastically press against the fixing part.

[0011] Furthermore, the locking mechanism also includes two springs. The connecting part of the movable block is narrower than the fixed part. The fixed part has two round holes. One end of the spring is inserted into the round hole, while the other end protrudes from the fixed part and is located on both sides of the connecting part. The other end of the spring extends outward until it presses against the inner wall surface of the limiting seat.

[0012] Furthermore, the chip connector includes two movable blocks and two cam portions that cooperate with the movable blocks, with an operating lever connected between the two cam portions.

[0013] Furthermore, the cam portion includes two parallel sides and an arcuate side connecting the parallel sides, and the distance between the pivot axis and the vertex of the arcuate side is less than the distance between the pivot axis and the parallel sides.

[0014] Furthermore, the operating lever is configured to be parallel to the parallel side.

[0015] Compared with the prior art, the present invention has the following advantages: the locking mechanism of the present invention can press against the chip to fix the chip in place, or it can be moved away from the chip to facilitate free placement and removal of the chip.

Specific embodiments

[0045] Please refer Figures 1 to 3 As shown, a chip connector 100 is used to test a chip 200. The chip connector 100 includes a body 10, a limit seat 20 that forms a receiving cavity 201 around the body 10, a fixed seat 80 located outside the limit seat 20, and a locking mechanism 30. The fixed seat 80 is a hollow frame structure, and the limit seat 20, the body 10, and the locking mechanism 30 are all located therein. The improvement of the present invention lies in that: the receiving cavity 201 is used to receive the chip 200, and the locking mechanism 30 can extend into the receiving cavity 201 to abut and lock the chip 200, preventing the chip from shaking during normal operation; in the non-operating state, the locking mechanism 30 is operated to move it away from the chip 200, facilitating the user to access the chip without obstacles.

[0046] Above the chip connector 100, there are provided a pressing component 60 pivotally connected above the fixed seat 80 and a heat dissipation component 70. The heat dissipation component 70 is fixed to the pressing component 60. One side of the pressing component 60 is pivotally connected to the fixed seat 80 and can rotate and press downward relative to the fixed seat 80 around a pivot axis. When the chip 200 is loaded into the receiving cavity 201, the pressing component 60 is rotated downward, thereby driving the heat dissipation component 70 to move downward and finally contact the chip 200, so as to conduct the heat generated during the testing of the chip 200. The pressing component 60 also provides a downward pressure on the chip 200 to achieve stable electrical connection with the terminals in the lower body 10. The body 10 carries conductive terminals (not shown), and the conductive terminals are electrically abutted against the chip 200. Refer Figure 6 , the body 10 is simultaneously installed on the PCB board 40, and the conductive terminals are also electrically connected to the PCB board. The heat dissipation backplane 50 is attached to the lower side of the PCB board to conduct the heat generated by the terminals. In this embodiment, the body 10 is installed above the PCB board 40 and is formed by stacking three insulator plates. The uppermost insulator plate 11 is a floating plate. When the chip 200 is pressed downward by force, it and the floating plate 11 move downward simultaneously. The two insulator plates located below the floating plate 11 are fixed sub-plates for fixing the conductive terminals (not shown).

[0047] Refer Figure 4-6As shown, the limiting seat 20 is installed on the body 10. It has four side walls 21, and the four side walls 21 enclose to form the above-mentioned receiving cavity 201 with an upward opening. The receiving cavity has a plurality of inner wall surfaces 202. At both ends of one of the side walls, bumps 22 are respectively protruded outward. The locking mechanism 30 is installed on the bumps 22 and is further restricted by the fixing seat 80.

[0048] Continuing to refer to FIGS. 7 - 11, the locking mechanism 30 is installed on the limiting seat 20. The locking mechanism 30 includes an operating part 31 and a fixing part 320. The operating part 31 drives the fixing part 32 to apply force to the chip 200 to fix the chip in the chip receiving cavity 201, or releases the fixing of the fixing part 32 on the chip 200. The chip 200 is assembled into the receiving cavity 201 from top to bottom, and the fixing part 32 enters the receiving cavity 201 along the lateral direction perpendicular to the up - down direction. The fixing part 320 passes through the inner wall surface 202 and can tightly press against the side surface of the chip 200. The locking mechanism 30 further includes a spring 33. The spring elastically presses against the fixing part 320 to increase the force applied by the fixing part to the chip 200. Thus, when the chip connector works, the chip 200 can be stably located in the receiving cavity 201. Refer to Figure 7-10 , specifically, the locking mechanism 30 includes a moving block 32, an operating rod 31, a spring 33 and a pivot shaft 34. The operating rod is the above - mentioned operating part 31. The operating rod 31 includes a cam part 310. The inner end of the moving block 32 forms the fixing part 320, and the opposite outer end passes through a through - hole (not shown) provided on the bump to form a connecting part 321. The connecting part 321 and the cam part are connected to each other through a pivot shaft 34. The cam part 310 presses against the outer wall surface of the side wall 21 and has different radii R. The operating part 31 rotates to make the cam part rotate, thereby driving the moving block 32 to move away from or close to the receiving cavity 201, refer to Figure 12-13 as shown.

[0049] Refer to Figure 12-13As shown, when the operating lever 31 is rotated upwards to a vertical position, the cam portion 310 presses against the outer wall surface of the sidewall with a larger radius R1. At this time, the moving block 32 moves outwards a certain distance, causing the fixed portion 320 to move away from the receiving cavity 201 and not to abut against the chip 200. When the operating lever 31 is rotated to a horizontal position, the cam portion 310 presses against the outer wall surface of the sidewall with a smaller radius R2 (R1 is greater than R2). At this time, the moving block 32 moves inwards a certain distance compared to the previous state, causing the fixed portion 320 to move closer to the receiving cavity 201 and finally abut against the chip 200. The two radii are specifically explained as follows: the cam portion 310 includes two parallel sides 311 and an arcuate side 312 connecting the parallel sides. The distance R2 between the pivot axis 34 and the vertex of the arcuate side is less than the distance R1 between the pivot axis 34 and the parallel side 311. When the fixing part 320 abuts against the chip 200, the chip 200 is securely housed in the receiving cavity 201. Rotating the above-mentioned operating part 31 causes the fixing part 320 to move away from the chip 200, at which point the chip 200 can be freely removed and placed.

[0050] like Figure 7-10 As shown, the spring 33 is disposed between the fixed part 320 and the inner wall surface of the side wall 21, and is designed to elastically press against the fixed part 320. Specifically, each side of the locking mechanism 30 includes two springs 33. The connecting part 321 of the moving block 32 is narrower than the fixed part 320. The fixed part has two round holes 322. One end of the spring is inserted into the round hole 322, while the other end protrudes from the fixed part 320 and is located on both sides of the connecting part 321. In the free state, the other end of the spring is close to the cam part 320 of the operating lever. When installed in the limiting seat 20 and in a compressed state, the other end of the spring extends outward until it presses against the inner wall surface 221 of the protrusion 22. Figure 11-13 As can be seen, when the spring 33 is compressed, it generates an inward resistance force on the fixing part 320, thereby increasing the inward force exerted by the fixing part 320 on the chip 200. The locking mechanism 30 has an axisymmetric structure, which includes two moving blocks 32 located on both sides and two cam parts 320 cooperating with the moving blocks. An operating lever 31 is connected between the two cam parts 320, and the operating lever 31 is arranged parallel to the aforementioned parallel side 311.
