Description of the embodiments
The present invention will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present invention more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
As shown in fig. 1, a printed circuit board assembly mounting structure for an internal electronic device body 13 implanted in a human or animal body. The plurality of connection holes distributed at the outer circumference and the center of the printed circuit board assembly 10 are connected with the support 12 through the plurality of connectors 11, and one end of the support 12 is fixed on the internal electronic device body 13. The dismounting fixture of the invention is applied to dismounting the circuit board assembly 10 and the internal electronic device body 13.
Referring to fig. 2-12, the PCBA disassembling jig includes a base 25, and a base 29 is connected to the lower side of the base 25 through a connection block 251. The two sides of the base 25 are respectively provided with a first cam slider 23 and a second cam slider 24. A cam rod 22 is arranged in the base 25 in a penetrating way, a claw support 27 is arranged in the base 25, and claws 28 are uniformly distributed on the periphery of the claw support 27.
One end of the cam rod 22 sequentially passes through the first cam slider 23, the base 25 and the jaw support 27 on one side of the base 25 to be connected with the second cam slider 24. The first cam slider 23 and the second cam slider 24 are fixed to the cam lever 22 by screws. The other end of the cam lever 22 is provided with a rotating lever 21. Rotation of the rotation lever 21 will cause the cam lever 22 to rotate, thereby driving the pawl 28 into motion.
Specifically, the jaw support 27 includes a support head 271 penetrating through the base 25 and a support ring 272 connected below the support head 271, and jaw retaining rings 273 are outwardly protruded from a circumference of the support ring 272, where the number of the jaw retaining rings 273 is the same as the number of the jaws 28. The pawl 28 is disposed inside the pawl catch ring 273.
The connecting block 251 is provided with a jaw driving block 26, the outer side of the jaw driving block 26 is abutted to the upper end of a jaw 28, the middle of the jaw is erected on a support ring 272 of a jaw support 27, and a gap 2721 is formed between the middle of the jaw and the root of the support ring 272. The outer wall of the claw 28 is provided with a blind hole, a spring 2a is embedded in the blind hole, the other end of the spring 2a is in compression abutting joint with the inner wall 34 of the claw retaining ring 273, and the compression amount of the spring 2a is larger than the transverse movement amount of the claw 28. When the claw driving block 26 moves towards the position of the circuit board assembly 10 along with the rotation of the cam rod 22, the claw 28 moves towards the gap 2721 under the action of the spring 2a until the circuit board assembly 10 is clamped, at this time, the upper end of the claw 28 is separated from the outer side wall of the claw driving block 26, so that the resistance when the subsequent claw lifts the circuit board assembly 10 can be further reduced.
Cam curved surface grooves 234 with arc-shaped sections are formed in the outer side surfaces of the first cam sliding block 23 and the second cam sliding block 24; the upper end of the jaw driving block 26 is placed in the cam curved surface groove 234 through the driving end 261. The arc angle of the cam curved surface groove is larger than 180 degrees.
The cam curved surface groove 234 includes a first cam curved surface groove section 2341 and a second cam curved surface groove section 2342, and the groove height of the second cam curved surface groove section 2342 is greater than the groove height of the first cam curved surface groove section 2341. The arc angle of the first section 2341 of the cam curved surface groove is 60 degrees, the groove height of the first section 2341 of the cam curved surface groove is in transition from shallow to deep, and the height difference of the two sections of grooves is larger than the transverse moving distance of the clamping jaw 28. When the rotating rod 21 rotates, the driving end 261 of the jaw driving block 26 is driven to transition from the first section 2341 of the cam curved surface groove to the second section 2342 of the cam curved surface groove, so that the jaw end 35 of the driving jaw 28 can move radially towards the circuit board assembly 10, and meanwhile, the clamping of the circuit board assembly 10 can be realized by matching with the pressing force of the spring 2 a.
In order to lift the clamping jaw 28 longitudinally and separate it from the internal electronic device body 13, the cam rod penetrating through the bracket head 271 has a cam-shaped cross section, i.e. includes a first cam end 37 and a second cam end 38, the first cam end 37 and the second cam end 38 have an arc shape, and the arc radius of the first cam end 37 is smaller than the arc radius of the second cam end 38. The center of the cam lever 22 is spaced from the top of the first cam end 37 less than the center of the cam lever 22 is spaced from the top of the second cam end 38.
The bracket head 271 has a waist-shaped hole 36 formed therein. When the cam lever 22 rotates in the kidney-shaped hole, up-and-down reciprocation of the jaw support 27 is achieved by contact of the cam end with the inner wall of the kidney-shaped hole 36. In this embodiment, in the initial state of the cam rod, the driving end of the claw driving block 26 is placed in the cam curved groove section 2341, and the first cam end 37 contacts with the kidney-shaped hole 36.
To ensure that the circuit board assembly 10 is smoothly disengaged from the connector 11, the upward movement is greater than the distance S the hole in the circuit board assembly 10 is inserted into the connector 11. That is, the distance from the center of the cam lever 22 to the top of the second cam end 38 is greater than the distance from the center of the cam lever 22 to the top of the first cam end 37.
