1. Technical Field
The present disclosure relates to a lubricant applicator.
2. Description of Related Art
Computer components, housed in a case, such as video cards, RAM, and many others, utilize an interface unit known as golden fingers, inserted into a corresponding interface slot or other similar interface. To facilitate insertion of such golden finger interfaces, a predetermined amount of lubricant is frequently applied to the golden fingers.
While the lubricant can be applied to the golden fingers manually, it is difficult to precisely govern the amount of lubricant applied. Excess lubricant can damage the motherboard and other components, while insufficient lubricant can impair proper insertion of the interface.
Therefore, what is needed is a lubricant applicator that can apply a predetermined amount of lubricant to the golden fingers.
The components in the drawings are not necessarily drawn to scale, the emphasis instead being placed upon clearly illustrating the principles of the lubricant applicator. Moreover, in the drawings, like reference numerals designate corresponding parts throughout the several views.
Referring to
The lubricant applicator 10 includes a base 20, a plate member 30, a plurality of elastic support members 40, a first cap 50, and a second cap 60. The base 20 includes a hollow space 21 for receiving lubricant.
The elastic members 40 may be coiled springs each having one end securely connected to the bottom surface of the hollow space 21. The plate member 30 is shaped to be slidably received in the hollow space 21 and supported by the elastic members 40. Upon receiving external force, the plate member 30 moves downwardly and the elastic members 40 are compressed. After the external force is removed, the plate member 30 recovers to its original position by the resilient force of the elastic members 40.
The plate member 30 includes a first slot 31 and a second slot 32 formed on an upper surface thereof. The first slot 31 and the second slot 32 are shaped to accommodate the golden finger interface of the device 100. The plate member 30 also includes a handle 33 for causing the plate member 30 to be moved downwardly.
In the exemplary embodiment, the plate member 30 further includes a plurality of through holes 34 disposed in the plate body thereof. When the plate member 30 moves downwardly to a predetermined position, lubricant stored in the hollow space 21 passes through the through holes 34 into the first slot 31 and the second slot 32.
In another embodiment, the plate member 30 may have a periphery smaller than that of the hollow space 21, such that a gap is formed between the plate member 30 and the side walls of the hollow space 21, through which the lubricant can pass into the first slot 31 and the second slot 32.
The first cap 50 is shaped to cover the hollow space 21 to prevent the lubricant from contamination. The first cap 50 includes a recessed cavity 51 shaped to accommodate the second cap 60. Two through slots 52 are formed in the bottom surface of the recessed cavity 51, each of which is positioned to be in correspondence with one of the first slot 31 and the second slot 32, such that the golden interface of the device 100 can be inserted through the slot 52 into the first slot 31 or the second slot 32.
The first cap 50 also includes a through opening 53 through which the handle 33 passes. The first cap 50 may be removably attached to the base 20 in any conventional manner. For example, the first cap 50 may include a hook and the base 20 may include a loop engaging with the hook to retain the first cap 50.
The second cap 60 includes a through opening 61 through which the handle 33 passes. The second cap 60 also includes a handle 62 allowing the plate member 30 to be moved downwardly. The second cap 60 is received in the cavity 51 and, when removed, exposes the slots 52 during application of lubricant to the golden finger interface.
During application of lubricant to the golden finger interface, the plate member 30 is moved downwardly via operating the handle 33 to allow the first slot 31 and the second slot 32 to receive lubricant. After the first slot 31 and second slot 32 are filled with lubricant, two devices 100 pass through the slots 52, causing the golden finger interfaces to be received in the first slot 31 and the second slot 32. Because the first slot 31 and the second slot 32 are designed according to the golden finger interface and filled with lubricant, each golden finger interface position in the first slot 31 or the second slot 32 receives a controlled amount of lubricant.
While one embodiment has been described and illustrated, the disclosure is not to be constructed as being limited thereto. Various modifications can be made to the embodiments by those skilled in the art without departing from the true spirit and scope of the disclosure as defined by the appended claims.
