In order to make the above features and advantages of the present invention more obvious, the following DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The preferred embodiments, together with the drawings, are described in detail below.

1 is a perspective view of a connector protection cover applied to a circuit board module according to an embodiment of the invention. Referring to FIG. 1 , the circuit board module 100 of the embodiment includes a circuit board 110 , a plurality of electronic components 120 , a connector 130 , and a connector protection cover 140 . These electronic components 120 are disposed on the circuit board 110. The connector 130 is disposed on the circuit board 110.

The electronic component 120 of the circuit board module 100 includes, for example, a central processing unit 120a, a memory 120b, and an interface card slot 120c. The circuit board module 100 further includes components such as a heat sink or a cooling fan disposed on the circuit board 110 ( Not shown).

2A is a perspective view of the connector protective cover and the connector of FIG. 1, and FIG. 2B is a perspective view showing a part of the structure of the connector protective cover and the connector of FIG. 1. Referring to FIG. 2A and FIG. 2B simultaneously, the connector 130 includes a plurality of connection terminals 132 connected to the circuit board 110 (shown in FIG. 1). The connector protection cover 140 includes a top wall 142, an annular side wall 144 connected to the top wall 142, and a partition structure 146.

The partition structure 146 is coupled to the annular sidewall 144. The top wall 142, the annular side wall 144 and the partition structure 146 define a plurality of accommodation spaces S. The partition structure 146 and the annular side wall 144 serve to sandwich the connection terminal 132 such that the connection terminal 132 is located in the accommodation space S.

Referring to FIG. 2A, in the embodiment, the outer surface of the annular sidewall 144 has at least one rib 144a (shown as two), and the connector 130 is further An outer frame 134 is included. The outer frame 134 has a notch 134a for engaging the notch 134a of the outer frame 134 to limit the direction in which the connector protection cover 140 is fixed to the connector 130 through structural interference. This can avoid damage to the connection terminal 132 due to a wrong direction when the connector protection cover 140 is fixed to the connector 130.

The connector 130 further includes a base 136 disposed on the circuit board 110 and covering one end of the connection terminal 132 adjacent to the circuit board 110. In addition, the outer frame 134 and the base 136 can be integrally formed by the injection molding manufacturing method.

The outer surface of the top wall 142 has an identification symbol 142a for the user to distinguish the type of the connector 130 covered by the connector protection cover 140. The connector 130 is, for example, a 1394 connector or a universal serial bus connector. In the present example, the partial region R of the annular side wall 144 adjacent the top wall 142 is at an acute angle A with the top wall 142, thereby making the connector protective cover 140 a T-like structure. This allows the user to easily remove the connector cover 140 from the connector 130.

Referring to FIG. 2B , in the embodiment, the annular sidewall 144 is a square annular sidewall, and the partition structure 146 can be simultaneously connected to the top wall 142 and the annular sidewall 144 or only to the annular sidewall 144 . A width D2 of each of the receiving spaces S is substantially equal to a thickness D1 of each of the connecting terminals 132 such that the partitioning structure 146 and the annular side wall 144 are used to collectively clamp the connecting terminals 132. In addition, the partition structure 146 has a plurality of grooves F to allow the connector protection cover 140 to save material usage during the manufacturing process of injection molding.

It is worth noting that because the connector protection cover 140 is connected through the pair The terminal 132 is fixed to the connector 130 by the clamping, and is not fixed to the connector 130 through the outer frame 134 or the base 136. Therefore, the connector protection cover 140 can also be applied to the connector without the outer frame 134 and the base 136.

In this embodiment, the outer surface of the annular sidewall 144 has a plurality of rib structures 144b, and the side of each rib structure 144b away from the top wall 142 has a guiding slope P. The guiding ramp P has a guiding function to make the connector protection cover 140 easier to fix to the connector 130. The rib structure 144b is used to abut the outer frame 134 (shown in FIG. 2A) to enable the connector protection cover 140 and the connector 130 to be tightly coupled by elastic deformation.

In summary, the connector protection cover of the circuit board module of the present invention can be fixed and covered by a connector on the circuit board. This can prevent the computer assembler or the user from mistakenly inserting the wrong transmission device into the connector, so as to reduce the probability of damage to the computer peripheral device connected to the connector due to the wrong voltage.

Although the present invention has been disclosed in the above preferred embodiments, it is not intended to limit the invention, and any one of ordinary skill in the art can make some modifications and refinements without departing from the spirit and scope of the invention. Therefore, the scope of the invention is defined by the scope of the appended claims.
