Description

Description Card Handle Insertion Mechanism and Method
BACKGROUND OF THE INVENTION Field of the Invention
[1] This application relates generally to mounting brackets. More particularly, the application relates to a handle assembly for inserting and extracting a circuit board assembly from an electronic chassis.
Description of the Related Art
[2] An electronic chassis which houses electronic components for high speed computing, telecommunication, and networking applications typically includes a plurality of vertically oriented circuit board assemblies that are inserted into the chassis. Each circuit board assembly is typically attached to a U-shaped channel member that serves as a front faceplate of the assembly. When the assembly is fully inserted, the circuit board is connected to a backplane located along the backside of the chassis. The insertion force required to connect the circuit board to the backplane may make it difficult, if not impossible, for a technician to make the connection by manually forcing the faceplate in a direction towards the backplane.
[3] In order to facilitate the connection of the circuit board to the backplane, attempts have been made to provide a lever at each end of the faceplate, each lever having a handle portion and a hook portion. Each lever is typically rotatably attached to each end of the faceplate and is able to rotate freely about a pin, which forces the circuit board into the backplane. When installing the assembly, a technician must orient each hook portion so it engages a bar that is fixed to the chassis while simultaneously pushing the faceplate in the direction of the backplane. After each hook portion engages the bar, the handle portion of each lever is then manually rotated about the pin, which forces the circuit board into the backplane. However, this known configuration suffers from a number of shortcomings.
[4] One disadvantage of this arrangement is that the hook portion may not align correctly with the fixed bar on the chassis when it is initially inserted. Instead of engaging the bar in between its two fingers, the hook may be pushed in too high or too low to properly engage with the bar. This makes it difficult and time consuming for a technician to insert the circuit board assembly.
[5] Another shortcoming of the prior art lever is that it is arranged on the inner side of the faceplate and pivots into the circuit board, thereby infringing on valuable board real estate. Space on the faceplate is also impaired, lessening the availability of room for ports and LED definitions.
[6] Accordingly, there is a need for an improved handle assembly for mounting a circuit board assembly to a chassis that facilitates insertion and removal, as well as maximizes the amount of space available on the circuit board and faceplate.
SUMMARY OF THE INVENTION
[7] An apparatus for mounting a circuit board assembly to an electronic chassis is provided herein. The apparatus includes a bar fixed on the chassis, a circuit board assembly, a first mounting assembly externally mounted onto the circuit board assembly, the first mounting assembly including a handle, the handle including a pivot portion having a hook portion and a top side, and the hook portion including at least one set of generally parallel fingers for engaging the bar and enabling rotation of the handle upon insertion of the circuit board assembly. The apparatus further includes means for pivotably mounting the first mounting assembly onto the circuit board assembly. The pivot portion further includes a locking mechanism which is secured to firmly lock the circuit board assembly to the chassis.
[8] An improved method of inserting and removing the circuit board assemblies is also described. When inserted into the chassis, the spring pushes the handle into an insertion position for engagement with the bar. The mounting assembly is inserted into the chassis until the set of generally parallel fingers engage the bar, the short finger passing under the bar and the long finger contacting the bar. The handle is then pushed inward toward the chassis to a closed position causing it to rotate around a pivot point, and the locking mechanism may then be secured to lock the circuit board assembly into the chassis. For removal, the locking mechanism is unsecured and the handle is pulled outward from the circuit board assembly back into the open position. This rotation causes the long finger to push against the bar, which ejects the circuit board assembly from the chassis.
[9] The apparatus may be pivotably mounted on the outer portion of the circuit board assembly with a U-shaped bracket member to maximize the amount of available space on both the circuit board and the faceplate for various machinery, such as ports and LED definitions.
[10] These as well as other aspects and advantages of the apparatus and method will become apparent from reading the following detailed description, with appropriate reference to the accompanying drawings.

[17] With reference to Figure 1, the card handle insertion mechanism described herein includes a circuit board assembly 100. The circuit board assembly 100 is to be injected into an electronic chassis (not shown). A faceplate 200 may be mounted onto the circuit board assembly 100. The faceplate has a first side 210, a second side 220, a first end 230, and a second end 240, as shown in Figure 2A. The first side 210 of the faceplate is mounted to the circuit board assembly 100. A mounting assembly 300 located at the first end 230 of the second side 220 of the faceplate 200 facilitates alignment of the circuit board assembly 100 with the chassis by engaging an inject/ eject bar 400 fixed on the chassis, which is shown in Figure 2B. A second mounting assembly 302 is mounted to the second side 220 of the second end 240 of the faceplate 200, as shown in Figure 2A. The two mounting assemblies 300 and 302 work together to facilitate insertion and ejection of the circuit board assembly 100 from the chassis. Alternatively, the mounting assemblies 300, 302 may be externally mounted directly onto the circuit board assembly 100 in a position in front of the board to maximize the amount of available space on the circuit board.
[18] As shown in Figure 2B, the first mounting assembly 300 includes means for pivotably mounting the first mounting assembly 300 onto the circuit board assembly 100. The means for pivotably mounting the first mounting assembly 300 may comprise a bracket member 310, which is mounted to the second side 220 of the first end 230 of the faceplate 200. Alternatively, the means for pivotably mounting the first mounting assembly 300 may comprise a rivet, a screw, or any other fastening means for securing the first mounting assembly directly to the circuit board assembly 100.
[19] The bracket member 310 is U-shaped and includes a first side 311 , a second side
312, and a third side 313, as shown in Figure 3. The first side 311 of the U-shaped bracket 310 is fastened to the faceplate 200 by, for example, a plurality of screws 314 and a stud 315. Other configurations of the bracket are also possible.
[20] The mounting assembly 300 further includes a handle 330 having a pivot portion
320 including a top side 321 and a pivot point 326. The pivot portion 320 is connected to the second side 312 and third side 313 of the U-shaped bracket 310 in a position opposite the faceplate 200, as shown in Figure 3. The pivot portion 320 is rotatably fastened to the second side 312 and third side 313 of the U-shaped bracket 310 by a mounting pin 318. In Figures 2A and 2B, the first mounting assembly 300 is shown with the handle 330 in an open, or insertion, position, while the second mounting assembly 302 is shown with the handle 330 in a closed, or engaged, position. A coil spring 317 is fastened to the mounting pin 318. The spring 317 causes the handle 330 to rotate from the closed position to the insertion position, such that when the circuit board assembly 100 is installed into the chassis, the handle is properly oriented to engage the bar 400.
[21] The pivot portion 320 of the handle includes a hook portion having at least one set of generally parallel fingers 322, 324. Each at least one set of generally parallel fingers comprises a long finger 322 located adjacent the top side 321 of the pivot portion, and a short finger 324 located below the long finger 322. The asymmetry of the length of the fingers 322, 324 facilitates their engagement with the bar 400 fixed on the chassis, as best seen in Figure 4. When the handle 330 is pushed inward toward the faceplate 200 to the closed position, the short finger 324 passes under the bar 400 and the long finger 322 contacts the bar, causing the handle 330 to rotate around its pivot point 326, and thereby injecting the circuit board assembly 100 into the chassis. The spring 317 ensures that the fingers 322 and 324 are properly aligned for engagement with the bar 400.
[22] The pivot portion 320 also includes a locking mechanism 328 mounted to its top side. The locking mechanism 328 secures the circuit board assembly 100 in place once it has been inserted into the chassis. The locking mechanism may also be secured during shipment or storage of the mounting assembly. When secured, the locking mechanism 328 engages a hex nut (not shown) fastened onto the stud 315 to hold the handle 330 in the closed position and secure the circuit board assembly 100 to the chassis. Other types of locking mechanisms may also be used. The second mounting assembly 302 is shown with the handle 330 in the closed position in Figure 2A. In preparation for insertion, the spring 317 pre-positions the handle 330 by allowing a user to simply undo the handle locking mechanism 328 and let the spring 317 push the handle 330 to the full open position for engagement with a bar 400 fixed on the chassis.
[23] The asymmetry of the fingers 322, 324 also facilitates removal of the circuit board assembly 100. During removal of the circuit board assembly 100, the locking mechanism 328 is unsecured and the handle 330 is pulled outward from the faceplate 200 back into the open position. This rotation causes the long finger 322 to push against the bar 400, which ejects the circuit board assembly 100 from the chassis.
[24] The second mounting assembly 302 functions identically to the first mounting assembly 300, but is located at the second end 240 of the second side 220 of the faceplate 200 and is rotated 180° from the first mounting assembly 300.
[25] The first mounting assembly 300 is externally mounted onto the faceplate 200 and circuit board assembly 100 to maximize the amount of available space on both the circuit board and the faceplate. The first mounting assembly 300 may also be externally mounted directly onto the circuit board assembly 100. This opens up space for additional ports and LED definitions.
[26] A method of inserting the circuit board assembly 100 into the chassis is also provided. If the mounting assembly was recently shipped or in storage, the locking mechanism may already be secured. In preparation for insertion, the spring 317 prepositions the handle 330 by allowing a user to simply undo the handle locking mechanism 328 and let the spring 317 push the handle 330 to the full open position for engagement with a bar 400 fixed on the chassis. When inserted into the chassis, the handle 330 is pushed inward toward the faceplate 200 into a closed position, in the direction shown in Figure 5 by arrow A. The motion of the generally parallel fingers is illustrated by arrow B. When the user pushes the card into the chassis slot, the short finger 324 passes under the bar 400 fixed on the chassis and the long finger 322 contacts the bar, causing the handle 330 to rotate around its pivot point 326. The handle 330 may then be pushed inward toward the faceplate 200 into the closed position to inject the circuit board assembly 100 into the chassis. The locking mechanism 328 is then secured, thereby locking the circuit board assembly 100 to the chassis.
[27] For removal of the circuit board assembly 100 from the chassis, the locking mechanism 328 is unsecured and the handle 330 is pulled outward from the faceplate 200 back into the open position. This rotation causes the long finger 322 to push against the bar 400, which ejects the circuit board assembly 100 from the chassis.
[28] While certain features and embodiments of the present invention have been described in detail herein, it is to be understood that the invention encompasses all modifications and enhancements within the scope and spirit of the following claims.
