请参照图4，本实用新型另一实施例的热插拔风扇3，其构成组件与功能均与热插拔风扇2相似，不同之处在于：该热插拔风扇3更包括一固定扣23A设置于连接部212中，以及浮动连接器22A的衔接部222A末端具有一止挡部228。固定扣23A具有一滑槽231且滑槽231的内部具有一倒勾(请参阅图5A及图5B)，衔接部222A滑设于滑槽231内，用以限制浮动连接器22相对于扇框21以单一方向(例如Y方向)浮动。此外，端子座221的宽度W′略小于容置部211的宽度W，用以使浮动连接器22可相对于扇框21作Z方向的浮动。Please refer to Fig. 4, the hot-swap fan 3 according to another embodiment of the present invention has similar components and functions to the hot-swap fan 2, the difference is that the hot-swap fan 3 further includes a fixing buckle 23A The connecting portion 222A disposed in the connecting portion 212 and the end of the floating connector 22A has a stop portion 228 . The fixing buckle 23A has a slide groove 231 and the inside of the slide groove 231 has a barb (please refer to FIG. 5A and FIG. 5B ). 21 floats in a single direction (eg, Y direction). In addition, the width W′ of the terminal seat 221 is slightly smaller than the width W of the accommodating portion 211 , so that the floating connector 22 can float relative to the fan frame 21 in the Z direction.

浮动连接器22相对于固定扣23A的浮动方式如下所述。如图4所示，固定扣23A的滑槽231为呈长圆形的穿孔且具有一倒勾，浮动连接器22A的衔接部222A也对应设置为长圆柱且末端具有止挡部228。浮动连接器22A是通过衔接部222A滑设于滑槽231内，故端子座221能相对于热插拔风扇3作Y方向浮动。此外，端子座221的宽度W′略小于容置部211的宽度W，故端子座221可相对于热插拔风扇3同时产生Z方向浮动。因此，浮动连接器22A相对于热插拔风扇3的扇框同时产生一维或二维浮动，用以确保热插拔风扇3与外部系统准确电连接。The floating manner of the floating connector 22 relative to the fixing buckle 23A is as follows. As shown in FIG. 4 , the sliding groove 231 of the fixing buckle 23A is an oblong through hole with a barb, and the engagement portion 222A of the floating connector 22A is also correspondingly arranged as a long cylinder with a stopper portion 228 at the end. The floating connector 22A is slidably disposed in the sliding slot 231 through the connecting portion 222A, so the terminal base 221 can float in the Y direction relative to the hot-swap fan 3 . In addition, the width W′ of the terminal base 221 is slightly smaller than the width W of the accommodating portion 211 , so the terminal base 221 can float in the Z direction relative to the hot-swap fan 3 at the same time. Therefore, the floating connector 22A generates a one-dimensional or two-dimensional floating relative to the fan frame of the hot-swap fan 3 to ensure that the hot-swap fan 3 is electrically connected to the external system accurately.

以下以图5A及图5B进一步说明浮动连接器22A与扇框21的连接关系：图5A显示浮动连接器装设于扇框的示意图；以及图5B显示图5A的部分放大图。在图5A中，浮动连接器22A的衔接部222A穿设于固定扣23A的滑槽231中，以进一步与扇框21的连接部212结合。衔接部222A的末端具有止挡部228，以及滑槽231中设有倒勾232。如图5B所示，通过倒勾232以及止挡部228的设计，可确保浮动连接器22A在Z方向的浮动，并避免固定扣23A由连接部212滑出掉落。5A and 5B further illustrate the connection relationship between the floating connector 22A and the fan frame 21: FIG. 5A shows a schematic diagram of the floating connector installed on the fan frame; and FIG. 5B shows a partially enlarged view of FIG. 5A. In FIG. 5A , the engaging portion 222A of the floating connector 22A passes through the slide groove 231 of the fixing buckle 23A to further combine with the connecting portion 212 of the fan frame 21 . An end of the engaging portion 222A has a stopper portion 228 , and a barb 232 is disposed in the slide groove 231 . As shown in FIG. 5B , through the design of the barb 232 and the stop portion 228 , the floating connector 22A can be ensured to float in the Z direction, and the fastening buckle 23A can be prevented from slipping out from the connecting portion 212 and falling off.

图6显示又一实施例的浮动连接器装设于扇框的示意图。本实施例不同于图5A所示的实施例在于：扇框21的连接部212内设有一倒勾232A，故浮动连接器22A的衔接部222A可穿设于连接部212中。通过倒勾232A以及衔接部22A的止挡部228的设计，可确保浮动连接器22A在Z方向的浮动。在本实施例中，由于扇框21的连接部212内设有倒勾232A，故不需固定扣即可完成浮动连接器与扇框的连接。FIG. 6 shows a schematic diagram of another embodiment of the floating connector installed on the fan frame. This embodiment is different from the embodiment shown in FIG. 5A in that: the connecting portion 212 of the fan frame 21 is provided with a barb 232A, so the connecting portion 222A of the floating connector 22A can pass through the connecting portion 212 . Through the design of the barb 232A and the stop portion 228 of the connecting portion 22A, the floating of the floating connector 22A in the Z direction can be ensured. In this embodiment, since the barb 232A is provided in the connecting portion 212 of the fan frame 21 , the connection between the floating connector and the fan frame can be completed without fixing buckles.

在本实用新型的所有实施例中，固定扣23及23A的滑槽231是一穿孔型态以分别容置衔接部222及222A。依据本实用新型的概念，该滑槽231也可为一凹槽型态，只要将衔接部滑设于滑槽以达成连接器的浮动即可。In all the embodiments of the present invention, the sliding slots 231 of the fixing buckles 23 and 23A are perforated to accommodate the connecting parts 222 and 222A respectively. According to the concept of the present invention, the sliding groove 231 can also be a groove type, as long as the connecting portion is slid on the sliding groove to realize the floating of the connector.

又，在本实用新型的所有实施例中，衔接部与固定扣分别为凸柱与穿孔或凹槽的对应型态。依据本实用新型的概念，衔接部也可为穿孔或凹槽且固定扣为凸柱的对应型态，只要达成连接器的浮动即可。Moreover, in all the embodiments of the present invention, the connecting portion and the fixing buckle are the corresponding types of the protruding post and the perforation or the groove respectively. According to the concept of the present invention, the connecting portion can also be a corresponding type of perforation or groove and the fixing buckle is a protrusion, as long as the floating of the connector is achieved.

综上所述，本实用新型的一种热插拔风扇通过连接器的衔接部及端子座的结构设置，使连接器相对于扇框作一维方向或二维方向浮动。与现有技术相比较，本实用新型配合外部系统的连接端子，使浮动连接器作接合位置与角度的调整，故能够确保热插拔风扇与外部系统准确电连接，进而提升电连接的可靠度。To sum up, the hot-swappable fan of the present invention makes the connector float in a one-dimensional or two-dimensional direction relative to the fan frame through the structural arrangement of the connecting portion of the connector and the terminal base.
