Description

TECHNICAL FIELD

[0001] The present invention relates to an electronic module and a connector protection cover, and more particularly, to an electronic module with a connector protection cover and a connector protection cover. BACKGROUND

[0002] In the current electronic module, the connector is directly inserted into the connector of the electronic module. However, if the electronic module is turned over in the system, the angle and distance of the wire of the connector inserted into the connector will change, and the insertion of the connector and the connector will be pulled, causing the signal transmission of the electronic module in the system to be unstable (such as speed reduction or loss of connection), thereby reducing the reliability of the use of the electronic module. SUMMARY

[0003] One of the purposes of the present invention is to provide an electronic module with a connector protection cover, so that the connector and the connector connected to each other have good reliability.

[0004] Another purpose of the present invention is to provide a connector protection cover which can make the connector and the connector connected to each other have good reliability.

[0005] An electronic module of the present invention is suitable for inserting a connector. The electronic module includes a circuit board, a connector and a connector protection cover. The circuit board has a first surface, a second surface opposite to the first surface, and a first positioning hole and two second positioning holes penetrating through the first surface and the second surface. The first positioning hole has a first side surface, and each second positioning hole has a second side surface and a third side surface connected to the second side surface. The connector is disposed on the first surface of the circuit board, and the connector is located between the first positioning hole and the two second positioning holes. The connector protection cover is detachably assembled to the circuit board and covers the connector. The connector protection cover includes a first positioning component, a second positioning component and a third positioning component. The first positioning component abuts against the first side surface of the first positioning hole and the second side surface of each second positioning hole to limit the movement of the connector protection cover in a first direction. The second positioning component abuts against the third side surface of each second positioning hole to limit the movement of the connector protection cover in a second direction. The third positioning component includes at least one hook and a cover bottom surface. The cover bottom surface abuts against the first surface of the circuit board, and the at least one hook abuts against the second surface of the circuit board to limit the movement of the connector protection cover in a third direction.

[0006] In an embodiment of the present invention, the above-mentioned connector protection cover further includes a main body portion, a first extension portion and two second extension portions. The main body portion includes oppositely disposed first and second side walls. The first extension portion extends from the first side wall of the main body portion and extends into the first positioning hole. The two second extension portions extend from the second side wall of the main body portion and extend into the two second positioning holes, respectively. The first positioning component is formed on the first inner surface of the first extension portion and the two second inner surfaces of the two second extension portions.

[0007] In one embodiment of the present application, each of the second extensions has a side surface. A second positioning assembly is formed on the side surface of each of the second extensions.

[0008] In one embodiment of the present application, the at least one hook includes a first hook and a second hook. The first hook is connected to the first extension relative to the body portion. The second hook is connected to one of the two second extensions relative to the body portion. A cover bottom surface is formed on the body portion.

[0009] In one embodiment of the present application, the first inner wall surface of the first side wall has an abutting rib. The abutting rib is adapted to abut a plug of the connector.

[0010] In one embodiment of the present application, the guide rib of the electronic module protrudes from the second inner wall surface of the second side wall and the second inner surface of the second extension. The guide rib has a slope at the position of the second inner surface.

[0011] In one embodiment of the present application, the first outer wall surface of the first side wall has a reinforcing rib away from the first extension. The height of the reinforcing rib protruding from the first outer wall surface gradually increases toward the first extension.

[0012] In one embodiment of the present application, the positioning holes of the circuit board are a plurality of heat dissipation holes.

[0013] In one embodiment of the present application, the connector has a connector bottom surface and a plurality of connector side surfaces connected to the connector bottom surface. The connector bottom surface contacts the first surface of the circuit board. One of the connector side surfaces has an area greater than that of the connector bottom surface.

[0014] A connector cover of the present application is adapted to be detachably assembled to a circuit board and cover a connector. The circuit board has a first surface, a second surface opposite to the first surface, and a first positioning hole and two second positioning holes penetrating through the first surface and the second surface. The first positioning hole has a first side surface. Each of the second positioning holes has a second side surface and a third side surface connected to the second side surface. The connector is disposed on the first surface of the circuit board and located between the first positioning hole and the two second positioning holes. The connector is adapted to have a plug inserted thereinto. The connector cover includes a first positioning assembly, a second positioning assembly, and a third positioning assembly. The first positioning assembly abuts the first side surface of the first positioning hole and the second side surface of each of the second positioning holes to limit movement of the connector cover in a first direction. The second positioning assembly abuts the third side surface of each of the second positioning holes to limit movement of the connector cover in a second direction. The third positioning assembly includes at least one hook and a cover bottom surface. The cover bottom surface abuts the first surface of the circuit board. The at least one hook abuts the second surface of the circuit board to limit movement of the connector cover in a third direction.

[0015] Based on the above, in the design of the electronic module of the present application, the connector protection cover is detachably assembled to the circuit board and covers the connector to protect the connector which has weak structural strength, and the movement of the connector protection cover in the first direction, the second direction and the third direction is respectively limited by the first positioning assembly, the second positioning assembly and the third positioning assembly of the connector protection cover, so as to enhance the stability between the connector protection cover and the circuit board. Thus, when the joint inserted in the connector is pulled and collided by the outside, the connector protection cover can reduce the shaking of the joint, so that the joint and the connector connected with each other have good protection, and the joint has good tensile resistance and damage resistance, thereby avoiding the situation that when the electronic module is flipped relative to the system, the joint and the connector are pulled due to the change of the angle and distance of the wire of the joint inserted in the connector, so as to cause speed reduction or signal interruption, and the reliability of the electronic module is improved.

[0077] Referring to FIG. 2 , in the present embodiment, the connector 120 is disposed on the first face 111 of the circuit board 110, and the connector 120 is located between the first positioning hole 113 and the two second positioning holes 114. The connector 120 has a connector bottom face 121 and four connector side faces 122, and a plug-in interface 123 of the connector 120 is adapted to be inserted by the contact 50.FIG. 5A )。

[0078] In detail, in the present embodiment, the connector side surfaces 122 are connected to the connector bottom surface 121, and the connector bottom surface 121 contacts the first surface 111 of the circuit board 110. The area of one of the connector side surfaces 122 is greater than the area of the connector bottom surface 121, so that the connection strength and the structural strength of the connector 120 provided on the circuit board 110 and the circuit board 110 are weak. It should be noted that, in the present embodiment, the connector 120 is a vertical connector, but is not limited thereto.

[0079] Referring to FIG. 3 to FIG. 5B , in the present embodiment, the connector protection cover 130 is detachably assembled to the circuit board 110 and covers the connector 120 FIG. 4A , FIG. 4B , so as to improve the structural strength between the connector 120 and the connector protection cover 130, the joint 50 FIG. 5A , and the circuit board 110, the connector 120 and the connector protection cover 130.

[0080] In detail, referring to FIG. 5A and FIG. 5B , in the present embodiment, the connector protection cover 130 includes a first positioning assembly 131, a second positioning assembly 132 and a third positioning assembly 133. The first positioning assembly 131 abuts against the first side surface 113-1 of the first positioning hole 113 and the second side surface 114-1 of each of the second positioning holes 114 FIG. 5B , so as to limit the movement of the connector protection cover 130 in the first direction D1. The second positioning assembly 132 abuts against the third side surface 114-2 of each of the second positioning holes 114, so as to limit the movement of the connector protection cover 130 in the second direction D2. The third positioning assembly 133 includes four hooks 134 FIG. 5B and a cover bottom surface 135. The cover bottom surface 135 abuts against the first surface 111 of the circuit board 110, and the four hooks 134 abut against the second surface 112 of the circuit board 110, so as to limit the movement of the connector protection cover 130 in the third direction D3.

[0081] Further, referring to FIG. 5A to FIG. 6B , in the present embodiment, the connector protection cover 130 further includes a main body portion 130a, a first extension portion 131a and two second extension portions 132a. The main body portion 130a includes oppositely arranged first and second side walls 130a-1 and 130a-2. The first extension portion 131a extends from the first side wall 130a-1 of the main body portion 130a and extends into the first positioning hole 113, and the two second extension portions 132a extend from the second side wall 130a-2 of the main body portion 130a and extend into the two second positioning holes 114FIG. 5A ). The four clamping hooks 134 include two first clamping hooks 134-1 and two second clamping hooks 134-2 ( FIG. 5B ). The first clamping hooks 134-1 are connected to the first extension 131a with respect to the body portion 130a, and the second clamping hooks 134-2 are connected to the two second extensions 132a with respect to the body portion 130a, respectively. The cover bottom surface 135 is formed on the body portion 130a.

[0082] Furthermore, please refer to FIG. 6A and FIG. 6B In the present embodiment, the first positioning assembly 131 is formed on the first inner surface 131a-1 ( FIG. 6B ) of the first extension 131a, and the second positioning assembly 132 is formed on the two second inner surfaces 132a-1 ( FIG. 6A ) of the two second extensions 132a, respectively.

[0083] Therefore, when the user assembles the connector cover 130 to the circuit board 110 and covers the connector 120 as shown in FIG. 3 , the first inner surface 131a-1 ( FIG. 6B ) of the first extension 131a and the two second inner surfaces 132a-1 ( FIG. 6A ) of the two second extensions 132a can be abutted against the first side surface 113-1 of the first positioning hole 113 and the second side surface 114-1 of each second positioning hole 114, respectively, to limit the movement of the connector cover 130 in the first direction D1. Meanwhile, the side surface 132a-2 of each second extension 132a is abutted against the third side surface 114-2 of each second positioning hole 114, respectively, to limit the movement of the connector cover 130 in the second direction D2. Moreover, the cover bottom surface 135 is abutted against the first surface 111 of the circuit board 110, and the two first clamping hooks 134-1 and the two second clamping hooks 134-2 are abutted against the second surface 112 of the circuit board 110, to limit the movement of the connector cover 130 in the third direction D3.

[0084] In this way, when the plug 50 inserted in the connector 120 is pulled or collided by external force, the shaking of the plug 50 can be reduced by the connector cover 130, so that the connected plug 50 and connector 120 have good protection, and the plug 50 has good resistance to pulling and destruction, thereby avoiding the situation that the speed is reduced or the signal is interrupted due to the change of the length of the wire (not shown) of the plug 50 inserted in the connector 120 when the electronic module 100 is flipped relative to the electronic system 10, and the plug 50 and the connector 120 are pulled at the plug-in position, and thus the reliability of the electronic module 100 is improved.

[0085] In addition, in the present embodiment, since the connector cover 130 covers the connector 120 FIG. 4A , FIG. 4B ) and is assembled to the circuit board 110, and the connector cover 130 only contacts the circuit board 110 and the plug-in connector 50 of the connector 120 without directly contacting the connector 120, the influence of external force on the connector 120 can be reduced, thereby protecting the connector 120 with weak structural strength.

[0086] Please refer to FIG. 3 and FIG. 5A , in the present embodiment, the first inner wall surface 130a-1a of the first side wall 130a-1 has two abutting ribs 136 FIG. 3 . These abutting ribs 136 are adapted to abut the plug-in connector 50 of the connector 120 FIG. 5A . Therefore, when the plug-in connector 50 is inserted into the connector 120 and the connector cover 130 as shown in FIG. 5A , the connector cover 130 will be in close contact with the plug-in connector 50 around to limit the movement of the plug-in connector 50, thereby reducing the influence of external pulling and collision on the plug-in connector 50.

[0087] Please refer to FIG. 6A , in the present embodiment, three guide ribs 137 are respectively protruded from the second inner wall surface 130a-2a of the second side wall 130a-2 and the second inner surface 132a-1 of one of the two second extension parts 132a, and each guide rib 137 has an inclined surface 137a at the position of the second inner surface 132a-1. Therefore, as shown in FIG. 3 , when the connector cover 130 is assembled to the circuit board 110, the inclined surface 137a of the guide rib 137 of the connector cover 130 can be in contact with the circuit board 110, and the connector cover 130 can be assembled to the circuit board 110 along the inclined surface 137a of the guide rib 137, thereby making the connector cover 130 easier and smoother to assemble.

[0088] Please continue to refer to FIG. 6A , in the present embodiment, the first outer wall surface 130a-1b of the first side wall 130a-1 of the connector cover 130 has three reinforcing ribs 138 away from the first extension part 131a. The height H1 of each reinforcing rib 138 protruding from the first outer wall surface 130a-1b gradually increases in the direction towards the first extension part 131a. In this way, the strength of the structure of the connector cover 130 itself can be enhanced.

[0089] In summary, in the design of the electronic module of the present application, the connector protection cover is detachably assembled to the circuit board and covers the connector to protect the connector with weak structural strength, and the movement of the connector protection cover in the first direction, the second direction and the third direction is respectively limited by the first positioning assembly, the second positioning assembly and the third positioning assembly of the connector protection cover to strengthen the stability between the connector protection cover and the circuit board. Thus, when the joint inserted in the connector is pulled and collided by the outside, the connector protection cover can reduce the shaking of the joint, the joint and the connector connected with each other have good protection, and the joint has good tensile resistance and damage resistance, so as to avoid the situation that when the electronic module is flipped relative to the system, the joint and the connector are pulled due to the change of the wire length of the joint inserted in the connector, the joint and the connector are pulled to cause speed reduction or signal interruption, and the reliability of the electronic module is improved.

[0090] Although the present application has been disclosed with the above-mentioned embodiments, it is not intended to limit the present application, and those skilled in the art can make some changes and modifications without departing from the spirit and scope of the present application, so the protection scope of the present application shall be subject to the appended claims.
