FIG. 1 is a three-dimensional view of a connector protecting cover applied in a circuit board module according to an embodiment of the present invention.
FIG. 2A is a three-dimensional view of the connector protecting cover and the connector in FIG. 1.
FIG. 2B is a three-dimensional view of the connector protecting cover and partial of the connector in FIG. 1.



DESCRIPTION OF THE EMBODIMENTS
Reference will now be made in detail to the present embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the description to refer to the same or like parts.
FIG. 1 is a three-dimensional view of a connector protecting cover applied in a circuit board module according to an embodiment of the present invention. Referring to FIG. 1, a circuit board module 100 in this embodiment includes a circuit board 110, a plurality of electronic devices 120, a connector 130, and a connector protecting cover 140. The electronic devices 120 are disposed on the circuit board 110. The connector 130 is disposed on the circuit board 110.
The electronic devices 120 of the circuit board module 100 includes, for example, a central processing unit (CPU) 120a, a memory 120b, an interface card socket 120c, and the circuit board module 100 further includes components such as a heat sink or a heat dissipation fan (not shown) disposed on the circuit board 110.
FIG. 2A is a three-dimensional view of the connector protecting cover and the connector in FIG. 1, and FIG. 2B is a three-dimensional view of the connector protecting cover and partial of the connector in FIG. 1. Referring to FIGS. 2A and 2B, the connector 130 includes a plurality of connecting terminals 132 connected to the circuit board 110 (shown in FIG. 1). The connector protecting cover 140 includes a top wall 142, a circular side wall 144 connected to the top wall 142, and a partition 146.
The partition 146 is connected to the circular side wall 144. The top wall 142, the circular side wall 144, and the partition 146 define a plurality of accommodation spaces S. The partition 146 and the circular side wall 144 are together used for clipping the connecting terminals 132, such that the connecting terminals 132 are located in the accommodation spaces S.
Referring to FIG. 2A, in this embodiment, an outer surface of the circular side wall 144 is provided with at least one rib 144a (two ribs are shown). The connector 130 further includes an outer frame 134 with a notch 134a disposed thereon. The rib 144a is snapped in the notch 134a of the outer frame 134, so that the direction for fixing the connector protecting cover 140 to the connector 130 is limited through a structural interference. Therefore, the connecting terminals 132 can be protected from being damaged due to the incorrect direction for fixing the connector protecting cover 140 to the connector 130.
The connector 130 further includes a base 136 disposed on the circuit board 110 and used for wrapping one end of each connecting terminal 132 close to the circuit board 110. Moreover, the outer frame 134 and the base 136 may be integrally formed through an injection moulding process.
An outer surface of the top wall 142 is provided with an identifier 142a for the user to identify the type of the connector 130 covered by the connector protecting cover 140, and the connector 130 is, for example, a 1394 connector or a universal serial bus (USB) connector. In this embodiment, a portion R of the circular side wall 144 adjacent to the top wall 142 forms an acute angle A with the top wall 142, such that the connector protecting cover 140 is formed into a T-like shaped structure. Therefore, the user can easily take the connector 130 from the connector protecting cover 140.
Referring to FIG. 2B, in this embodiment, the circular side wall 144 is a square circular side wall, and the partition 146 may be connected to both the top wall 142 and the circular side wall 144 or merely connected to the circular side wall 144. A width D2 of each of the accommodation spaces S is substantially equal to a thickness D1 of each of the connecting terminals 132, such that the partition 146 and the circular side wall 144 are together used for clipping the connecting terminals 132. Moreover, the partition 146 has a plurality of grooves F, so that the usage of the material may be saved during the injection moulding process for producing the connector protecting cover 140.
It should be noted that, since the connector protecting cover 140 is fixed to the connector 130 by clipping the connecting terminals 132, instead of being fixed to the connector 130 through the outer frame 134 or the base 136, the connector protecting cover 140 is also applicable to a connector without the outer frame 134 and the base 136.
In this embodiment, an outer surface of the circular side wall 144 is provided with a plurality of protruding ridges 144b, and each protruding ridge 144b has a guide chamfer P on one side far away from the top wall 142. The guide chamfer P has a guiding function, such that the connector protecting cover 140 can be easily fixed to the connector 130. The protruding ridges 144b are used to bear against the outer frame 134 (shown in FIG. 2A), such that the connector protecting cover 140 and the connector 130 may be combined tightly through a flexible deformation.
Based on the above, the connector protecting cover of the circuit board module in the present invention may be fixed to cover the connector on the circuit board. Therefore, the computer assembling personnel or the user is prevented from inserting an incorrect transmission device into the connector by mistake, and the possibility of damaging the computer peripherals connected to the connector due to an incorrect voltage is reduced as well.
It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the present invention without departing from the scope or spirit of the invention. In view of the foregoing, it is intended that the present invention cover modifications and variations of this invention provided they fall within the scope of the following claims and their equivalents.
