Description

Technical Field

[0001] This application relates to the field of circuit board technology, and more specifically, to an electronic module mounting bracket. Background Technology

[0002] A PCBA (Printed Circuit Board Assembly) is a printed circuit board assembly, formed by soldering various electronic components (such as chips, resistors, capacitors, and connectors) onto a PCB (Printed Circuit Board). During the manufacturing process, solder paste and flux are used for soldering, and flux residues can leave behind. These residues can cause short circuits during PCBA use. Therefore, PCBA boards must be cleaned before use.

[0003] PCBA boards need to be mounted on a mounting bracket for cleaning. Different sizes of PCBA boards require corresponding mounting brackets for fixing. Therefore, a large number of mounting brackets of different sizes need to be made to fix the PCBA boards. In large-volume cleaning operations, this leads to a decrease in cleaning speed and an increase in cost. Utility Model Content

[0004] The purpose of this application is to address the shortcomings of the prior art by providing an electronic module mounting bracket, thereby solving the problem that different sizes of electronic modules require corresponding mounting brackets for fixing, which leads to reduced cleaning speed and increased costs.

[0005] To achieve the above objectives, the technical solutions adopted in the embodiments of this application are as follows: In one aspect of this application, an electronic module mounting bracket is provided, including a frame with a hollow area for placing an electronic module. A first slide rail and a second slide rail, perpendicular to each other, are provided on the inner wall of the hollow area of ​​the frame. A first sliding member is slidably disposed on the first slide rail. After the first sliding member is driven to slide to cooperate with the frame in clamping the electronic module along the extension direction of the first slide rail, the first sliding member switches to a locked state relatively fixed to the frame. When the first sliding member is switched to the locked state, a second sliding member is slidably disposed on the second slide rail and slidably connected to the first sliding member. After the second sliding member is driven to slide to cooperate with the frame in clamping the electronic module along the extension direction of the second slide rail, the second sliding member switches to a locked state relatively fixed to the frame.

[0006] Optionally, the electronic module mounting bracket includes a plurality of second sliding members, which are alternately connected to a second slide rail and a first sliding member. The length of the second sliding member connected to the second slide rail and the first sliding member is the same as the length of the electronic module held by the second sliding member in the extension direction of the first slide rail. Optionally, the electronic module mounting bracket includes a first limiting member, which is rotatably connected to the frame. The first limiting member is driven to rotate to cooperate with the first slide rail and the second slide rail to clamp the electronic module along the thickness direction of the electronic module.

[0007] Optionally, the electronic module mounting bracket further includes a positioning element, which includes a connector and an abutment. Both ends of the connector are fixedly connected to the frame, one end of the abutment is fixedly connected to the connector, and the other end of the abutment abuts against the first sliding member and / or the second sliding member to switch to a locked state.

[0008] Optionally, the abutment includes a fixing block, a snap fastener, and an elastic element. One end of the fixing block is fixedly connected to the connector, and the other end is connected to the snap fastener. The elastic element is located between the fixing block and the snap fastener to provide the snap fastener and the first slide rail or the second slide rail to clamp the first sliding element or the second sliding element. Optionally, the electronic module mounting bracket also includes a connecting frame and a connecting strip. The connecting frame is fixedly connected to the surface of the frame. The connecting frame has a groove, and the connector is fixedly connected to the groove via the connecting strip. Optionally, the electronic module mounting bracket further includes a second limiting member, which is rotatably connected to the positioning member. The second limiting member is driven to rotate to cooperate with the first slide rail and the second slide rail to clamp the electronic module along the thickness direction of the electronic module.

[0009] Optionally, the second limiting member is a spring sheet, and a transition surface is provided at the end of the spring sheet near the electronic module, through which the spring sheet abuts against the electronic module.

[0010] Optionally, the transition surface is a circular arc surface. Optionally, the electronic module mounting bracket also includes a base and a handwheel. The handwheel is fixedly connected to the outer periphery of the frame, and the base is rotatably connected to the frame. Driving the handwheel causes the frame to rotate relative to the base.

[0011] The beneficial effects of this application include: This application provides an electronic module mounting bracket, including a frame with a hollowed-out area, a first sliding member, and a second sliding member. The hollowed-out area of ​​the frame is used to place the electronic module. A first slide rail and a second slide rail, which are perpendicular to each other, are provided on the inner wall of the hollowed-out area. The first sliding member is slidably connected to the first slide rail. After the first slide rail is driven to slide along its extension direction to cooperate with the frame in clamping the electronic module, the first sliding member switches to a locked state that is fixed relative to the frame. At this time, the second sliding member is simultaneously slidably connected to both the second slide rail and the first sliding member. The second sliding member is driven to slide along the extension direction of the second slide rail to cooperate with the frame in clamping the electronic module. After the frame clamps the electronic module, the second sliding member switches to a locked state that is fixed relative to the frame. For electronic modules of different lengths and widths, the first sliding member slides and engages with the first slide rail to switch to a locked state to cooperate with the frame clamping the electronic module. Then, the second sliding member slides and engages with the second slide rail and the first sliding member to switch to a locked state to cooperate with the frame clamping the electronic module. The first sliding member, the second sliding member, and the frame jointly clamp the electronic module. By using an electronic module fixing bracket, the electronic modules of different lengths and widths can be fixed, which speeds up the cleaning rate of the electronic modules and reduces costs.

[0020] One aspect of the embodiments of this application, such as Figure 1As shown, an electronic module mounting bracket 100 is provided, including a frame 110. The frame 110 has a hollow area 111 for placing an electronic module 200. A first slide rail 112 and a second slide rail 113 perpendicular to each other are provided on the inner wall surface of the hollow area 111 of the frame 110. A first sliding member 120 is slidably disposed on the first slide rail 112. After the first sliding member 120 is driven to slide to cooperate with the frame 110 to clamp the electronic module 200 along the extension direction of the first slide rail 112, the first sliding member 120 switches to a locked state that is fixed relative to the frame 110. When the first sliding member 120 switches to the locked state, a second sliding member 130 is slidably disposed on the second slide rail 113 and slidably connected to the first sliding member 120. After the second sliding member 130 is driven to slide to cooperate with the frame 110 to clamp the electronic module 200 along the extension direction of the second slide rail 113, the second sliding member 130 switches to a locked state that is fixed relative to the frame 110.

[0021] Specifically, the electronic module mounting bracket 100 includes a frame 110, a first sliding member 120, and a second sliding member 130. A hollow area 111 is provided inside the frame 110 for mounting the electronic module 200. It should be noted that the hollow area 111 is located in the middle of the frame 110. A first slide rail 112 and a second slide rail 113 are provided on the inner wall of the hollow area 111 of the frame 110, and the first slide rail 112 and the second slide rail 113 are arranged perpendicularly to each other. The first sliding member 120 is slidably connected to the first slide rail 112, and the first sliding member 120 can switch between a sliding state and a locked state. The sliding state refers to driving the first sliding member 120 to slide along the extension direction of the first slide rail 112; the locked state refers to the first sliding member 120 cooperating with the frame 110 to clamp the electronic module 200, that is, the state in which the first sliding member 120 is fixed relative to the frame 110 is the locked state. When the first slider 120 is in the locked state, the second slider 130 is slidably connected to the second slide rail 113 and the first slider 120. That is, one end of the second slider 130 is slidably connected to the second slide rail 113, and the other end is slidably connected to the first slider 120. The second slider 130 can also switch between a sliding state and a locked state. The sliding state refers to the second slider 130 being positioned between the second slide rail 113 and the first slider 120 and sliding along the extending direction of the second slide rail 113; the locked state refers to the second slider 130 being fixed relative to the frame 110.

[0022] When it is necessary to fix the electronic module 200, the electronic module 200 is placed in the hollow area 111 of the frame 110, and the first slider 120 is driven to slide along the extension direction of the first slide rail 112, so that the first slider 120 switches from the sliding state to the locked state, such as... Figure 1As shown, the first slider 120 is in the locked state. In this state, the first slider 120 cooperates with the frame 110 to clamp the electronic module 200. For example, the first slider 120 and the frame 110 clamp the electronic module 200 to limit its degree of freedom along its length. When the first slider 120 is in the locked state, the second slider 130 is positioned between the second slide rail 113 and the first slider 120, so that the second slider 130 is simultaneously slidably connected to both the second slide rail 113 and the first slider 120. This drives the second slider 130 to slide along the extension direction of the second slide rail 113, causing the second slider 130 to switch from the sliding state to the locked state. Figure 1 As shown, the second slider 130 is in a locked state, at which time the second slider 130 cooperates with the frame 110 to clamp the electronic module 200. For example, the second slider 130 cooperates with the frame 110 to clamp and limit the degree of freedom of the electronic module 200 in the width direction. The first slider 120 and the second slider 130 are both in a locked state, and the electronic module 200 is clamped by the first slider 120, the second slider 130 and the frame 110. For electronic modules 200 of different lengths and widths, only the positions of the first slider 120 and the second slider 130 in the locked state are different. The electronic module fixing bracket 100 realizes the fixing of electronic modules 200 of different lengths and widths, speeds up the cleaning rate of the electronic module 200 and reduces costs.

[0023] In some embodiments, a third slide rail is provided on the first slider 120 so that the second slider 130 is slidably connected to the third slide rail and the second slide rail 113.

[0024] In some embodiments, the first slide rail 112 and the second slide rail 113 can be configured as slide grooves, and sliders that slide in cooperation with the slide grooves can be respectively provided on the first slider 120 and the second slider 130; alternatively, the first slide rail 112 and the second slide rail 113 can be configured as sliders, and slide grooves that slide in cooperation with the sliders can be respectively provided on the first slider 120 and the second slider 130; no limitation is made here.

[0025] In some implementations, the electronic module 200 may be a PCB (printed circuit board) or a PCBA (printed circuit board assembly), and no limitation is made here.

[0026] Optionally, such as Figure 1 As shown, the electronic module mounting bracket 100 includes a plurality of second sliding members 130, which are alternately connected to the second slide rail 113 and the first sliding member 120. The length of the second sliding member 130 connected to the second slide rail 113 and the first sliding member 120 is the same as that of the electronic module 200 held by the second sliding member 130 in the extension direction of the first slide rail 112. Specifically, the electronic module mounting bracket 100 includes multiple second sliding members 130. The number of second sliding members 130 can be determined according to the specifications of the electronic module 200, such as having two, three, four, or more second sliding members 130. The multiple second sliding members 130 are alternately connected to the second slide rail 113 and the first sliding member 120. That is, according to the specifications of the electronic module 200, only one second sliding member 130 is slidably connected to the second slide rail 113 and the first sliding member 120 at a time, and the length of the second sliding member 130 is the same as the length of the electronic module 200 along the extension direction of the first slide rail 112.

[0027] When it is necessary to fix the electronic module 200, the first slider 120 is switched from a sliding state to a locked state by driving it. Figure 1 As shown, the first slider 120 is in a locked state, so that the first slider 120 cooperates with the frame 110 to clamp the electronic module 200. When the first slider 120 is in the locked state, a second slider 130 is provided to slide in connection with the second slide rail 113 and the first slider 120; when fixing an electronic module 200 of a different specification, another second slider 130 is provided to slide in connection with the second slide rail 113 and the first slider 120, switching the second slider 130 from the sliding state to the locked state, as shown. Figure 1 As shown, the second slider 130 is in a locked state so that the first slider 120, the second slider 130 and the frame 110 together clamp the electronic module 200.

[0028] Optionally, such as Figure 1 As shown, the electronic module mounting bracket 100 includes a first limiting member 140, which is rotatably connected to the frame 110. The first limiting member 140 is driven to rotate to cooperate with the first slide rail 112 and the second slide rail 113 to clamp the electronic module 200 along the thickness direction of the electronic module 200.

[0029] Specifically, the electronic module holder 100 includes a first limiting member 140, which is disposed on the periphery of the surface of the frame 110 and rotatably connected to the frame 110. When the first sliding member 120, the second sliding member 130, and the frame 110 clamp the electronic module 200, the first limiting member 140 is driven to rotate, causing it to abut against the surface of the electronic module 200, thereby cooperating with the first slide rail 112 and the second slide rail 113 to clamp the electronic module 200 along its thickness direction. It should be noted that in this case, the first slide rail 112 and the second slide rail 113 are configured as sliding grooves, and sliders that slide in cooperation with the sliding grooves are respectively provided on the first sliding member 120 and the second sliding member 130. The electronic module 200 is clamped and limited by the first sliding member 120, the second sliding member 130, and the bottom of the sliding groove, and the first limiting member 140 and the groove wall clamp the electronic module 200 along its thickness direction.

[0030] Optionally, such as Figure 1 As shown, the electronic module mounting bracket 100 also includes a positioning member 150, which includes a connector 151 and an abutment member 152. Both ends of the connector 151 are fixedly connected to the frame 110, one end of the abutment member 152 is fixedly connected to the connector 151, and the other end of the abutment member 152 abuts against the first sliding member 120 and / or the second sliding member 130 to switch to a locked state.

[0031] Specifically, the electronic module mounting bracket 100 also includes a positioning member 150, which keeps the first sliding member 120 and the second sliding member 130 in a locked state. The positioning member 150 includes a connecting member 151 and an abutment member 152. Both ends of the connecting member 151 are fixedly connected to the frame 110 along its length. When the first sliding member 120 is in the locked state and cooperates with the frame 110 to clamp the electronic module 200, one end of the abutment member 152 is fixedly connected to the connecting member 151, and the other end of the abutment member 152 abuts against the first sliding member 120. The abutment member 152 and the first slide rail 112 clamp the first sliding member 120, thereby locking the first sliding member 120. Similarly, when the second slider 130 is in the locked state and cooperates with the frame 110 to clamp the electronic module 200, one end of the abutment 152 is fixedly connected to the connector 151, and the other end of the abutment 152 abuts against the second slider 130. The abutment 152 and the first slide rail 112 clamp the second slider 130, thus locking the second slider 130. It should be noted that the first slider 120 and the second slider 130 can be slidably connected to the first slide rail 112 and the second slide rail 113, respectively, using either a sliding groove or a slider.

[0032] Optionally, such as Figure 2As shown, the abutment member 152 includes a fixing block 1521, a snap fastener 1522, and an elastic member 1523. One end of the fixing block 1521 is fixedly connected to the connector 151, and the other end is connected to the snap fastener 1522. The elastic member 1523 is located between the fixing block 1521 and the snap fastener 1522 to provide the snap fastener 1522 with the first slide rail 112 to clamp the first sliding member 120 or with the second slide rail 113 to clamp the second sliding member 130.

[0033] Specifically, the abutment 152 includes a fixing block 1521, a snap fastener 1522, and an elastic element 1523. The elastic element 1523 is located between the fixing block 1521 and the snap fastener 1522. The fixing block 1521 is connected to the snap fastener 1522 via fasteners, and the snap fastener 1522 tends to move closer to or further away from the fixing block 1521. The elastic element 1523 abuts against the fixing block 1521 and the snap fastener 1522 at its two ends, providing force to the snap fastener 1522 to clamp the first sliding member 120 with the first slide rail 112, thus locking the first sliding member 120; or the elastic element 1523 provides force to the snap fastener 1522 to clamp the second sliding member 130 with the second slide rail 113, thus locking the second sliding member 130. The end of the fixing block 1521 away from the snap fastener 1522 is fixedly connected to the connector 151.

[0034] In some embodiments, the connection between the fixing block 1521 and the connector 151 can be a threaded connection, a snap-fit ​​connection, or a keyed connection, and the specific connection is not limited. Optionally, such as Figure 1 As shown, the electronic module mounting bracket 100 also includes a connecting bracket 160 and a connecting strip 170. The connecting bracket 160 is fixedly connected to the surface of the frame 110. The connecting bracket 160 has a groove, and the connector 151 is fixedly connected to the groove via the connecting strip 170.

[0035] Specifically, the electronic module mounting bracket 100 also includes a connecting bracket 160 and a connecting strip 170. The connecting bracket 160 surrounds the periphery of the surface of the frame 110 and is fixedly connected to the frame 110. A groove is provided in the middle of the connecting bracket 160, and the connecting member 151 is fixedly connected to the connecting bracket 160 through the connecting strip 170. Specifically, the connecting member 151 is fixedly connected to the groove of the connecting bracket 160.

[0036] In some embodiments, the connector 151 also has a groove, and the connector 170 fixes the connector 160 and the connector 151 by means of the fixed connection groove. Optionally, such as Figure 1As shown, the electronic module mounting bracket 100 also includes a second limiting member 180, which is rotatably connected to the positioning member 150. The second limiting member 180 is driven to rotate to cooperate with the first slide rail 112 and the second slide rail 113 to clamp the electronic module 200 along the thickness direction of the electronic module 200.

[0037] Specifically, the electronic module mounting bracket 100 also includes a second limiting member 180, which is disposed on and rotatably connected to the positioning member 150. More specifically, the second limiting member 180 is rotatably connected to the connecting member 151. When the first sliding member 120 is in the locked state, driving the second limiting member 180 to rotate causes it to abut against the surface of the electronic module 200, thereby cooperating with the first slide rail 112 and the second slide rail 113 to clamp the electronic module 200 along its thickness direction. When the second sliding member 130 is in the locked state, driving the second limiting member 180 to rotate causes it to abut against the surface of the electronic module 200, thereby cooperating with the first slide rail 112 and the second slide rail 113 to clamp the electronic module 200 along its thickness direction. It should be noted that, in this case, the first slide rail 112 and the second slide rail 113 are set as slide grooves, and sliders that slide in cooperation with the slide grooves are respectively set on the first slider 120 and the second slider 130. The second limiting member 180 and the first limiting member 140 clamp the electronic module 200 in the same way, which will not be described in detail here.

[0038] Optionally, the second limiting member 180 is a spring sheet, and a transition surface is provided at one end of the spring sheet near the electronic module 200, through which the spring sheet abuts against the electronic module 200.

[0039] Specifically, the second limiting member 180 is a spring sheet. One end of the spring sheet is rotatably connected to the positioning member 150. Driving the spring sheet causes the other end of the spring sheet to abut against the electronic module 200. A transition surface is provided at the end near the electronic module 200 so that the spring sheet contacts the surface of the electronic module 200, preventing the spring sheet from scratching the electronic module 200.

[0040] In some embodiments, the first limiting member 140 is also a spring sheet. One end of the spring sheet is rotatably connected to the frame 110. Driving the spring sheet causes the other end of the spring sheet to abut against the electronic module 200. A transition surface is provided at the end near the electronic module 200 so that the spring sheet contacts the surface of the electronic module 200, preventing the spring sheet from scratching the electronic module 200.

[0041] Optionally, the transition surface is a circular arc surface.

[0042] Specifically, the transition surface is set as an arc surface. The arc surface can prevent the spring from scratching the electronic module 200, and it also makes it easier to grab the spring to drive its rotation.

[0043] In some embodiments, the electronic module holder 100 includes a plurality of first limiting members 140 and a plurality of second limiting members 180, for example, there are two, three or four or more such members. The plurality of first limiting members 140 and the plurality of second limiting members 180 have different lengths to cooperate with the first slide rail 112 and the second slide rail 113 to clamp the electronic module 200 at different positions along the thickness direction of the electronic module 200.

[0044] Optionally, such as Figure 3 The electronic module mounting bracket 100 also includes a base 190 and a handwheel 191. The handwheel 191 is fixedly connected to the outer periphery of the frame 110, and the base 190 is rotatably connected to the frame 110. The handwheel 191 is driven to make the frame 110 rotate relative to the base 190.

[0045] Specifically, the electronic module holder 100 also includes a base 190 and a handwheel 191. The base 190 supports the frame 110 and is rotatably connected to the frame 110. The handwheel 191 serves as a drive unit and is fixedly connected to the outer periphery of the frame 110. The first sliding member 120, the second sliding member 130, and the frame 110 together hold the electronic module 200. When the front of the electronic module 200 is cleaned, the handwheel 191 is driven to rotate the frame 110 relative to the base 190, that is, the electronic module 200 rotates to clean the back of the electronic module 200.

[0046] In some implementations, the base 190 and the frame 110 can be rotatably connected by bearings or hinges, and there are no specific limitations.

[0047] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
