Description

Technical Field

[0001] This invention belongs to the technical field of domain controller testing equipment, and particularly relates to a locking mechanism and a testing box for a domain controller circuit board testing box. Background Technology

[0002] When performing functional testing on a domain controller circuit board (PCBA), the PCBA needs to be placed in a fixture, and the equipment uses a locking mechanism to lock the fixture in place.

[0003] Currently, most commercially available products use a cylinder to engage the fixture and connect it to the testing equipment. During the automatic engagement process, because the fixture and equipment are directly connected, it can easily damage the product pins, causing downtime. Furthermore, the need for a cylinder to pull the device results in severe wear and tear, leading to high maintenance costs. Summary of the Invention

[0004] This invention provides a locking mechanism and a test box for a domain controller circuit board test box, aiming to solve the problems mentioned in the background art.

[0005] The present invention is implemented as follows: a locking mechanism for a domain controller circuit board test box includes a support plate symmetrically arranged on the base of the test box, a locking pin symmetrically arranged on the box body of the test box, a locking plate that moves longitudinally inside the support plate to engage the locking pin with the support plate, and a driving mechanism arranged on the support plate to drive the locking plate to move. The end of the locking plate away from the base has a guide groove for engaging the locking pin.

[0006] Preferably, the support plate has an arc-shaped hole, and the card plate has an elongated hole A at the position corresponding to the arc-shaped hole.

[0007] Preferably, the drive mechanism includes a rotating shaft rotatably mounted on the support plate, a throttle and a connector respectively fixedly disposed at both ends of the rotating shaft corresponding to the outer side of the support plate, and a fixing pin passing through the arc-shaped hole and the elongated hole A, wherein the two fixing pins are respectively connected to the throttle and the connector.

[0008] Preferably, a positioning bolt penetrating the card plate is provided on the support plate at the position corresponding to the card plate.

[0009] Preferably, the card plate has an elongated hole B at the position corresponding to the positioning bolt.

[0010] A test chamber comprising the locking mechanism described above for a domain controller circuit board test chamber.

[0011] This locking mechanism has a simple structure and is easy to operate. Through the card plate, the guide slot set on the card plate, and the drive mechanism, the test box can be pre-connected. The drive mechanism drives the card plate to lock the card stop pin, which can effectively avoid the problem of pin damage caused by direct connection. At the same time, the card plate is locked by driving the drive mechanism, which does not require the cylinder to pull, making the operation convenient, effectively avoiding equipment wear, and facilitating maintenance.

[0014] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0015] The present invention discloses a locking mechanism for a domain controller circuit board test box. The locking mechanism includes a support plate 1 symmetrically arranged on the base of the test box, a locking pin 2 symmetrically arranged on the box body of the test box, a locking plate 3 that moves longitudinally inside the support plate 1 to engage the locking pin 2 with the support plate 1, and a driving mechanism arranged on the support plate 1 to drive the locking plate 3 to move. The end of the locking plate 3 away from the base has a guide groove 10 for engaging the locking pin 2.

[0016] When in use, place the circuit board PCBA inside the test box, then align the locking pin 2 on the box with the guide slot 10, and push the box close to the test box base. Then, drive the card plate 3 to slide through the drive mechanism, so that the locking pin 2 enters the guide slot 10 and locks the test box shell and the test box base.

[0017] Compared to direct docking, pre-docking is performed through guide slot 10 and stop pin 2. During pre-docking, the pins are in an unengaged state. Then, the drive mechanism moves the plate 3, causing the housing to dock with the interface on the test chamber base. This effectively avoids the problem of pin damage caused by direct docking. At the same time, the drive mechanism locks the plate, eliminating the need for cylinder pulling. This makes operation convenient, effectively avoids equipment wear, and facilitates maintenance.

[0018] Specifically, the support plate 1 has an arc-shaped hole 7, and the clamping plate 3 has an elongated hole A8 at the position corresponding to the arc-shaped hole 7. The driving mechanism includes a rotating shaft 4 rotatably mounted on the support plate 1, a handle 5 and a connector 6 respectively fixedly disposed at both ends of the rotating shaft 4 corresponding to the outer side of the support plate 1, and a fixing pin 9 passing through the arc-shaped hole 7 and the elongated hole A8. The two fixing pins 9 are respectively connected to the handle 5 and the connector 6.

[0019] When locking the test chamber, the rotating handle 5 is turned to drive the rotating shaft 4, connector 6 and fixing pin 9 to rotate. At this time, the fixing pin 9 rotates along the arc hole 7 and, with the cooperation of the long waist hole A8, drives the card plate 3 to move downward, so that the guide slot 10 on the card plate 3 is locked on the card stop pin 2, thereby locking the test chamber body and the test chamber base.

[0020] It should be noted that when the locking plate 3 is in the open state, the elongated hole A8 is located at the higher end of the arc-shaped hole 7, while in the locked state, the elongated hole A8 is located at the lowest end of the arc-shaped hole 7. When locked, the fixing pin 9 moves from the higher end of the arc-shaped hole 7 to the lower end, and in cooperation with the elongated hole A8, pushes the locking plate 3 downward, so that the locking plate 3 is engaged with the locking pin 2. Conversely, when opened, the handle drives the fixing pin 9 from the lowest end of the arc-shaped hole 7 to the highest end, so that the locking plate 3 releases the locking pin 2.

[0021] Furthermore, to prevent the clamping plate 3 from shifting under the rotational tendency of the throttle 5 and the shaft 4, and to ensure the stability of the clamping plate 3 structure, a positioning bolt 11 is provided on the support plate 1 at the position corresponding to the clamping plate 3, penetrating the clamping plate 3; an elongated hole B is provided on the clamping plate 3 at the position corresponding to the positioning bolt 11. It should be noted that at least two positioning bolts 11 are provided.

[0022] In addition, the present invention also provides a test box including the locking mechanism described above for a domain controller circuit board test box.

[0023] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
