Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, specifically to an automatic correction and plug-in device for testing equipment ports. Background Technology

[0002] After servers and other equipment are assembled, they need to undergo batch testing using testing equipment. However, due to the large number of connectors on the tested equipment, manual connector insertion is inefficient and prone to misalignment. Therefore, a dedicated automatic connector insertion device is required. However, the tested equipment not only has a large number of connectors, but also exhibits slight misalignment due to assembly errors, and the connectors themselves may not be completely fixed, exhibiting slight sway. Therefore, when using an automatic connector insertion device, the connector must be able to automatically correct its alignment; otherwise, mechanical force could damage the connectors. Existing automatic connector insertion devices typically use a flexible, sway-deformable spring along the insertion direction on the testing equipment. The connector is fixed to the free end of the spring, and a guide rod passes through the center line of the spring. The connector and the guide rod have a gap to allow for connector offset, and the spring's sway corrects the alignment and returns the connector to its original position. However, with prolonged use and repeated insertion and removal, the compression spring is prone to slight deformation, which may cause the connector to fail to return to the center position. This can lead to misalignment during automatic insertion in subsequent tests due to excessive offset, potentially damaging the tested equipment. Therefore, it is necessary to improve this feature. Utility Model Content

[0003] The purpose of this invention is to provide an automatic alignment and reset capability for a long time.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] An automatic correction and insertion device for a test equipment port includes a first mounting base, a linear device for driving the first mounting base to translate along the insertion direction, a plurality of first guide posts fixed to the front end of the first mounting base along the insertion direction, a first sliding seat adapted to slide through each of the first guide posts, a first limiting member disposed on the first guide post for limiting the maximum forward movement position of the first sliding seat, a first buffer spring sleeved on the first guide post and with both ends abutting between the first mounting base and the first sliding seat, four cylindrical steel needles fixed to the front end of the first sliding seat along the insertion direction, and insertion seats fixed to the front ends of the four steel needles; the four steel needles are distributed at the four corners of a rectangle; the steel needles can undergo elastic deformation perpendicular to their length direction under external force, and the deflection of the steel needles during the insertion process does not exceed 5mm.

[0006] In a preferred embodiment, the distribution centers of a plurality of the first guide posts coincide with the distribution centers of the four steel needles.

[0007] In a preferred embodiment, the first limiting member is a T-head located at the front end of the first guide post, and the rear end face of the first limiting member abuts against the front end face of the first sliding seat.

[0008] In a preferred embodiment, a mounting plate is further provided perpendicular to the insertion direction, wherein a plurality of the first mounting seats are arranged side by side on the mounting plate, and the mounting plate is connected to the movable end of the linear device.

[0009] In a preferred embodiment, the mounting plate is provided with a plurality of heat dissipation components, and the heat dissipation components can elastically extend and retract along the insertion direction.

[0010] In a preferred embodiment, the heat dissipation assembly includes a second mounting base fixed to the mounting plate, a plurality of second guide posts fixed to the front end of the second mounting base along the insertion direction, a second sliding seat adapted to slide through each of the second guide posts, a second limiting member disposed at the front end of the second guide posts to limit the maximum forward movement position of the second sliding seat, a second buffer spring sleeved on the second guide posts and with both ends abutting against the space between the second mounting base and the second sliding seat, and a heat sink fixedly mounted on the second sliding seat.

[0011] In a preferred embodiment, the top of the heat sink has a copper base that contacts the testing equipment, and the contact plane of the copper base is perpendicular to the insertion direction.

[0012] In a preferred embodiment, a side plate close to the heat dissipation component is fixed on the mounting plate, and a plurality of cooling fans facing the heat dissipation component are mounted on the side plate.

[0013] The beneficial effects of this utility model are as follows: the connector achieves alignment by elastically deforming perpendicular to the length direction of the steel pins through four steel pins distributed at the four corners of the rectangle. The deformation of the four steel pins restricts each other, so that the main sway direction of the connector is two perpendicular directions, and it can also be appropriately twisted. This is similar to the offset method of the connector interface of the tested equipment, so it is easier to align. Moreover, compared with the telescopic spring, the steel pins are not affected by the insertion and withdrawal tension force, are not prone to fatigue deformation, and can always be centered and reset, thus extending the service life of the connector. The first spring buffers the insertion and withdrawal direction, which can prevent the connector interface from being impacted during insertion and thus avoid damaging the tested equipment.

Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can also refer to the internal connection of two components; and they can refer to a wireless connection or a wired connection. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0020] refer to Figure 1As shown in the figure, an automatic correction and insertion device for a test equipment port includes a first mounting base 1, a linear device 2 for driving the first mounting base 1 to translate along the insertion direction, a plurality of first guide posts 3 fixed to the front end of the first mounting base 1 along the insertion direction, a first sliding seat 4 adapted to slide through each of the first guide posts 3, a first limiting member 31 disposed on the first guide post 3 for limiting the maximum forward movement position of the first sliding seat 4, a first buffer spring 32 sleeved on the first guide post 3 and with both ends abutting between the first mounting base 1 and the first sliding seat 4, four cylindrical steel needles 5 fixed to the front end of the first sliding seat 4 along the insertion direction, and an insertion seat 6 fixed to the front end of the four steel needles 5; the four steel needles 5 are distributed at the four corners of a rectangle; the steel needles 5 can undergo elastic deformation perpendicular to their length direction under the action of external force, and the deflection of the steel needles 5 during the insertion process does not exceed 5mm.

[0021] The connector 6 is used to fix the connector. The connector 6 completes the alignment by elastically deforming perpendicular to the length direction of the steel pins 5 through four steel pins 5 distributed at the four corners of the rectangle. The four steel pins 5 restrict each other's deformation, so that the main swing direction of the connector 6 is two perpendicular directions parallel to the two adjacent sides of the rectangle where the four steel pins 5 are distributed. It can also be appropriately torsional deformed. This is similar to the offset method of the connector of the device under test. That is, the connector of the device under test is square and has an installation gap. Therefore, the offset direction of the connector is mainly in two perpendicular directions, so it is easier to align. Moreover, compared with the telescopic spring, the steel pins 5 are not affected by the insertion and withdrawal tension, are not easy to fatigue and deform, and can always be centered and reset, extending the service life of the connector. The first spring 32 buffers the insertion and withdrawal direction, which can prevent the connector from being impacted during insertion and thus avoid damaging the device under test.

[0022] In a preferred embodiment, the distribution centers of the plurality of first guide posts 3 coincide with the distribution centers of the four steel pins 5. This ensures that the connector is subjected to balanced forces during insertion, removal, extension, and retraction.

In other embodiments, the limiting member may also be located on the first guide post 3 and inside the first sliding seat 4, and correspondingly, the sliding seat has a groove for the limiting member to slide.

[0024] In a preferred embodiment, the automatic insertion device further includes a mounting plate 7 arranged perpendicular to the insertion direction. Multiple sets of first mounting seats 1 are arranged side-by-side on the mounting plate 7, and the mounting plate 7 is connected to the movable end of the linear device 2. The mounting plate 7 has multiple sets of first mounting seats 1, allowing the linear device 2 to complete the insertion and removal of multiple connectors simultaneously. Each connector can independently achieve adaptive alignment, simplifying the structure of the insertion and removal device.

[0025] In a preferred embodiment, the mounting plate 7 is provided with a plurality of heat dissipation components 8, and the heat dissipation components 8 are elastically extendable and retractable along the insertion direction. Correspondingly, after the test insertion is completed, the heat dissipation components 8 can simultaneously dissipate heat from the device under test during the test.

[0026] In a preferred embodiment, the heat dissipation assembly 8 includes a second mounting base 81 fixed to the mounting plate 7, a plurality of second guide posts 82 fixed to the front end of the second mounting base 81 along the insertion direction, a second sliding seat 83 adapted to slide through each of the second guide posts 82, a second limiting member 821 disposed at the front end of the second guide posts 82 to limit the maximum forward movement position of the second sliding seat 83, a second buffer spring 822 sleeved on the second guide posts 82 and with both ends abutting against the space between the second mounting base 81 and the second sliding seat 83, and a heat sink 84 fixedly mounted on the second sliding seat 83. Similarly, the second spring 822 can form a buffer to prevent the heat dissipation assembly 8 from impacting and damaging the tested equipment during docking.

[0027] In a preferred embodiment, the top of the heat sink 84 has a copper base 841 that contacts the test equipment, and the contact plane of the copper base 841 is perpendicular to the insertion direction.

[0028] In a preferred embodiment, a side plate 9 is fixed to the mounting plate 7 near the heat dissipation assembly 8, and a plurality of cooling fans 91 facing the heat dissipation assembly 8 are mounted on the side plate 9. The cooling fans 91 can accelerate the heat exchange of the heat sink 84 and improve the heat dissipation efficiency.
