Please refer to fig. 1. Fig. 1 is a perspective view of an extension connector 100 according to an embodiment of the present invention. In the present embodiment, as shown in fig. 1, an extension connector 100 includes a base plate 110 and a clamping structure 120. The base plate 110 has a through hole H configured to allow the fixing member 200 (see fig. 2 to 3) to pass therethrough. For example, the through hole H of the bottom plate 110 is circular, but the invention is not limited thereto. The clamping structure 120 is coupled to the base plate 110, the through hole H is spaced apart from the clamping structure 120 along a first direction D1, the clamping structure 120 and the base plate 110 together define a groove G facing a second direction D2, and the groove G is configured to at least partially receive the circuit card 300 therein, and the second direction D2 is opposite to the first direction D1.

Structurally, the clamping structure 120 further includes a positioning plate 121 and a connecting portion 122. The positioning plate 121 has a first clamping surface S1, and the first clamping surface S1 of the positioning plate 121 faces at least partially toward the bottom plate 110. The connecting portion 122 is connected between the positioning plate 121 and the bottom plate 110, and the first clamping surface S1 of the positioning plate 121 is located in the second direction D2 of the connecting portion 122 and adjacent to the connecting portion 122.

Further, the bottom plate 110 has a second clamping surface S2, the second clamping surface S2 is located in the second direction D2 of the connecting portion 122 and adjacent to the connecting portion 122, and the second clamping surface S2 of the bottom plate 110 faces at least partially toward the first clamping surface S1 of the positioning plate 121. It is noted that the first clamping surface S1 of the positioning plate 121, the second clamping surface S2 of the bottom plate 110 and a side surface 123 of the connecting portion 122 of the clamping structure 120 away from the through hole H define a groove G, and the groove G faces at least partially toward the second direction D2, as mentioned above, i.e., the opening of the groove G is away from the through hole H of the bottom plate 110.

Furthermore, the first clamping surface S1 of the positioning board 121, the second clamping surface S2 of the bottom board 110 and a side surface 123 of the connecting portion 122 of the clamping structure 120 away from the through hole H jointly define a groove G extending along a third direction D3, and the third direction D3 is substantially perpendicular to the first direction D1 and the second direction D2.

In addition, the center line CL of the through hole H extends along the fourth direction D4, and the fourth direction D4 is substantially perpendicular to the first direction D1, the second direction D2 and the third direction D3. In practical applications, the fixing element 200 (see fig. 2-3 for the fixing element 200) can pass through the through hole H along the fourth direction D4.

More specifically, the bottom plate 110 includes a main plate 111 and two sub-plates 112, the through holes H are located on the main plate 111, the sub-plates 112 are respectively connected to the main plate 111, and the sub-plates 112 are at least partially arranged along the third direction D3 and separated from each other, the sub-plates 112 have sub-clamping surfaces S2a, in other words, the sub-clamping surfaces S2a are at least partially arranged along the third direction D3 and separated from each other. In the present embodiment, the sub-clamping surfaces S2a of the sub-board 112 collectively define a second clamping surface S2.

More specifically, the sub-boards 112 of the bottom plate 110 have a distance T therebetween in the third direction D3, and the positioning plate 121 also has a length L in the third direction D3. In the present embodiment, for example, the distance T between the sub-boards 112 is greater than the length L of the positioning plate 121, but the invention is not limited thereto.

Please refer to fig. 2 to 3. Fig. 2 is a top view of the extension connector 100 of fig. 1 in use. Fig. 3 is an application side view of the extension connector 100 of fig. 1. In practical applications, as shown in fig. 2 to 3, one end of the circuit card 300 is at least partially received in the groove G of the extended connector 100, and the first clamping surface S1 of the positioning plate 121 and the second clamping surface S2 of the bottom plate 110 can abut against the circuit card 300, but the invention is not limited thereto. The other end of the circuit card 300, in contrast, is connected to the connection structure 410 of the circuit board 400. The circuit card 300 can be fixed to the circuit board 400 by the extension connector 100 by connecting the circuit board 400 with the fixing member 200 through the through hole H of the extension connector 100 in the fourth direction D4. For example, the fixing member 200 may be a screw structure and correspond to a screw hole N of the circuit board 400 (see fig. 3 for the screw hole N).

In this embodiment, the circuit card 300 may be a Wireless Wide Area Network (WWAN) card, but the invention is not limited thereto. In fact, the length of the wlan card is not fixed, and for simplicity, the wlan card is divided into a long card and a short card.

As shown in fig. 3, circuit card 300 is a wireless wide area network short card. One end of the wireless wan short card (i.e., the circuit card 300) is at least partially received in the groove G of the extension connector 100, and the other end of the wireless wan short card (i.e., the circuit card 300) is connected to the connecting structure 410 of the circuit board 400, and is connected to the screw hole N of the circuit board 400 by passing the fixing member 200 through the through hole H of the extension connector 100 along the fourth direction D4, so that the wireless wan short card (i.e., the circuit card 300) can be fixed on the circuit board 400 by the extension connector 100.

However, when the circuit card 300 is a wireless wide area network (ww an) card, under the condition that one end of the wireless wan card (i.e. the circuit card 300) is connected to the connecting structure 410 of the circuit board 400, the fastener 200 passes through the wireless wan card (i.e. the circuit card 300) directly along the fourth direction D4 to connect the screw hole N of the circuit board 400, so as to fix the wireless wan card (i.e. the circuit card 300) on the circuit board 400. That is, the WWAN long card (i.e., the circuit card 300) may be directly mounted on the circuit board 400 without using the extended connector 100.

Simply stated, the wireless wide area network long card (i.e., the circuit card 300) is fixed to the circuit board 400 without using the extension connector 100. However, when the circuit card 300 is a wireless wide area network short card, the wireless wide area network short card (i.e., the circuit card 300) can be fixed on the circuit board 400 by the connection with the extension connector 100. Thus, when designing the circuit board 400, the user only needs to provide one connection point (i.e., the screw hole N) on the circuit board 400 to which the fixing element 200 can be connected, and does not need to consider that a plurality of connection points (i.e., the screw holes N) suitable for connecting the long card and the short card of the wireless wide area network are provided on the circuit board 400 at the same time. Therefore, by using the extension connector 100, the number of connection points on the circuit board 400 can be reduced, thereby effectively increasing the area on the circuit board 400 where the circuit can be laid, and facilitating space utilization and circuit routing in circuit design.

Furthermore, in the present embodiment, the wireless wan card (i.e. the circuit card 300) and the extension connector 100 are fixed by receiving a portion of the wireless wan card (i.e. the circuit card 300) in the groove G of the extension connector 100, and this process does not require additional tools, thereby providing convenience to the user.

In summary, the technical solutions provided by the above embodiments of the present invention have at least the following advantages:
