Description

Technical Field

[0001] This utility model relates to the field of connection mechanism technology, and in particular to a connection mechanism for testing the backplate of a cooling fan. Background Technology

[0002] As a circuit board, the cooling fan backplane is used for testing. Generally, the backplane under test is connected to the motherboard via a cable, and the backplane under test is connected to multiple fan devices. Then, the server motherboard is powered on and the test program is run to verify the various functions of the backplane.

[0003] During the testing of cooling fan backplates, a large number of fans are required for testing. Existing connection mechanisms are usually plug-in terminals, and frequent plugging and unplugging can easily damage the terminal interfaces, causing deviations in test results. Therefore, a connection mechanism for testing cooling fan backplates is needed to meet people's needs. Utility Model Content

[0004] The purpose of this utility model is to provide a connection mechanism for testing the backplate of a cooling fan, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a connection mechanism for testing a cooling fan backplate, comprising a connector body, wherein a first hole is provided at both ends of the connector body, a second hole is provided between the two first holes, a guide plate is embedded in the second hole, a spring is connected to the end of the first hole near the second hole, a sliding sleeve is connected to the spring, the sliding sleeve is slidably connected in the first hole, a plurality of elastic plates are provided on the inner wall of the sliding sleeve, the plurality of elastic plates are arranged in a circumferential shape at equal intervals and are contracted from the outside to the inside, a protective sleeve is provided at the end of the first hole near the second hole, the protective sleeve is arranged between the sliding sleeve and the plurality of elastic plates.

[0006] Preferably, a first limiting ring is provided on the outer wall of the end of the sliding sleeve that is connected to the spring, the first limiting ring is slidably adapted to the first hole, and a second limiting ring is provided on the inner wall of the opening of the first hole, the sliding sleeve is slidably adapted to the second limiting ring.

[0007] Preferably, one end of the sheath has a tapered hole, and several elastic sheets slide and fit into the tapered hole.

[0008] Preferably, a pull ring is provided on one end of the sliding sleeve outside the connector body, and the pull ring has the same shape as the connector body.

[0009] Preferably, a first connecting block and a second connecting block are respectively provided on both sides of the connector body. A trapezoidal groove is provided on the first connecting block, and a trapezoidal block is connected to the second connecting block. The trapezoidal block can fit tightly with the trapezoidal groove.

[0010] Preferably, the connector body, sliding sleeve, elastic sheet, sheath, first limiting ring, second limiting ring, pull ring, first connecting block, second connecting block and trapezoidal block are all made of PC flame-retardant material.

[0011] The beneficial effects of this utility model are:

[0012] In this invention, the connection mechanism allows for quick plugging and unplugging during the testing of the cooling fan backplate. One end retains the terminal block as the fixed end, while the other end retains the exposed copper wire as the plug-in end. This connection mechanism ensures conductivity and effectively avoids plugging and unplugging operations between terminals, preventing damage to the terminals and improving the accuracy of test results.

[0013] In this invention, by pulling out the sliding sleeve, the spring is stretched and deformed by the tension force, causing the sliding sleeve to move several elastic plates away from the sheath. The contracted ends of the elastic plates are no longer restricted by the inner wall of the sheath, allowing expansion when the connecting wire is inserted. After the sliding sleeve is released, the elastic force of the stretched spring causes the sliding sleeve to move into the connector body, and also causes several elastic plates and the connecting wire clamped between the elastic plates to move inward. After contacting the inner wall of the sheath, the elastic plates contract inward to clamp the rubber layer outside the connecting wire. Furthermore, the tension of the spring ensures that the exposed copper wire end of the connecting wire is always in contact with the guide plate, thereby ensuring conductivity and improving the stability of the connecting wire.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Reference Figure 1-3 A connection mechanism for testing a cooling fan backplate includes a connector body 1. First holes 2 are formed at both ends of the connector body 1, and a second hole 3 is formed between the two first holes 2. A guide plate 4 is embedded in the second hole 3. A spring 5 is connected to the end of the first hole 2 near the second hole 3, and a sliding sleeve 6 is connected to the spring 5. The sliding sleeve 6 is slidably connected within the first hole 2. A plurality of elastic plates 7 are arranged on the inner wall of the sliding sleeve 6, with the elastic plates 7 arranged in a circumferential, equally spaced pattern and contracting from the outside in. A protective sleeve 8 is provided at the end of the first hole 2 near the second hole 3, and the protective sleeve 8 is positioned between the sliding sleeve 6 and the plurality of elastic plates 7.

[0020] This connection mechanism allows for quick plug-in / plug-out connections during the testing of the cooling fan backplate. One end retains the terminal block as the fixed end, while the other end retains the exposed copper wire as the plug-in end. This ensures conductivity while effectively preventing plugging and unplugging operations between terminals, thus avoiding damage and improving test accuracy. During testing, the corresponding wires are connected through the same connector body 1. Pulling out the sliding sleeve 6 causes the spring 5 to stretch and deform, causing the sliding sleeve 6 to move several elastic plates 7 away from the sheath 8. The retracted ends of the elastic plates 7 are no longer restricted by the inner wall of the sheath 8, allowing the wires to be inserted smoothly. Now, after the expansion and insertion of the connecting wire, the sliding sleeve 6 is released. The elastic force of the stretched spring 5 drives the sliding sleeve 6 to move into the connector body 1, and drives several elastic plates 7 and the connecting wire clamped between the elastic plates 7 to move inward. After the elastic plates 7 contact the inner wall of the sheath 8, they contract inward to clamp the rubber layer outside the connecting wire. Under the tension of the spring 5, the exposed copper wire end of the connecting wire is always in contact with the guide plate 4, thereby ensuring the conductivity and improving the stability of the connecting wire. After the test is completed, the sliding sleeve 6 can be pulled out to remove the external restriction of the elastic plates 7, and the connecting wire can be shaken. The connecting wire can be taken out from the inside by applying an expansion force to the elastic plates 7.

[0021] Specifically, in this embodiment, a first limiting ring 9 is provided on the outer wall of the end of the sliding sleeve 6 that is connected to the spring 5. The first limiting ring 9 is slidably adapted to the first hole 2. A second limiting ring 10 is provided on the inner wall of the opening of the first hole 2. The sliding sleeve 6 is slidably adapted to the second limiting ring 10, providing a limit for the sliding sleeve 6 to be pulled outward.

[0022] Specifically, in this embodiment, a tapered hole 11 is provided at one end of the sheath 8, and several elastic sheets 7 slide and fit into the tapered hole 11, which helps the elastic sheets 7 to contract more effectively.

[0023] Specifically, in this embodiment, a pull ring 12 is provided on one end of the sliding sleeve 6 outside the connector body 1. The pull ring 12 has the same shape as the connector body 1, which makes it convenient for the operator to apply pulling force to the sliding sleeve 6.

[0024] Specifically, in this embodiment, a first connecting block 13 and a second connecting block 14 are respectively provided on both sides of the connector body 1. A trapezoidal groove 15 is provided on the first connecting block 13, and a trapezoidal block 16 is connected to the second connecting block 14. The trapezoidal block 16 can fit tightly with the trapezoidal groove 15, which helps multiple connector bodies 1 to connect to each other for matching connection.

[0025] Specifically, in this embodiment, the connector body 1, sliding sleeve 6, elastic sheet 7, sheath 8, first limiting ring 9, second limiting ring 10, pull ring 12, first connecting block 13, second connecting block 14 and trapezoidal block 16 are all made of PC flame-retardant material, and the non-conductive and flame-retardant properties improve the safety performance in use.

[0026] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
