Embodiment

Hereinafter with reference to correlative type, a kind of hot-plug fan according to the utility model preferred embodiment is described, wherein components identical will be illustrated with identical reference marks.

As shown in Figure 2, a kind of hot-plug fan 2 of the utility model one embodiment comprises a fan frame 21 and a float connector 22.Hot-plug fan 2 can be an axial flow fan; The periphery of fan frame 21 has a holding part 211 and two joints 212; And joint 212 is arranged at the both sides of holding part 211.In the present embodiment, these joints 212 are arranged at the relative both sides of holding part 211, but not as limit.

Float connector 22 has a terminal base 221 and two convergence parts 222, and these convergence parts 222 are arranged at the both sides of terminal base 221.In the present embodiment, these convergence parts 222 are arranged at the relative both sides of terminal base 221, and corresponding to the joint 212 of fanning frame 21.The section of terminal base 221 is to be the L type, and these convergence parts 222 are arranged at the both sides of the corner of L type terminal base 221, and can with terminal base 221 one-body molded making.The shape of convergence part 222 is such as but not limited to oval column, circular cylindrical shape, square column or polygonal column.

Be noted that fan these joints 212 of frame 21 and these convergence parts 222 of float connector 22 can be symmetrical arranged or asymmetric setting, that is the position is set can be the both sides of symmetry or shift to install.The aperture of joint 212 is greater than the size of convergence part 222, with so that one dimensional motion or two dimensional motion are carried out with respect to joint 212 in convergence part 222, make connector float be provided with, and then promote the degree of accuracy that is electrically connected and the reliability of hot-plug fan 2 and outer welding system.

Float connector 22 has a plurality of terminals 224 and a slot 225.These terminals 224 are electrically connected to a motor (figure does not show) of hot-plug fan 2, and are electrically connected with outer welding system, make motor start according to the drive signal of outer welding system.These terminals 224 can be cutting knife type terminal, make or form conductive material in its surface with plating mode for example with conductive material.In addition, each cutting knife type terminal 224 has a fixing part 224a, and it is the overhead kick shape and is fixedly arranged on slot 225.Terminal base 221 has positioning piece 226, and it is that a non-conductive material is made, and can with terminal base 221 one-body molded making.Locating piece 226 is used to make external system when these terminals 224 of electric connecting terminal stroma 221, can contraposition and accurately connect, and locating piece 226 more can have a lead angle with auxiliary contraposition.Float connector 22 has more a display element 227, such as but not limited to a light emitting diode (Light Emitting Diode, LED), in order to the signal of demonstration hot-plug fan 2 with the connecting state of outer welding system, or the signal of demonstration hot-plug fan 2 states own.

Please refer to shown in Figure 3ly, in hot-plug fan when assembling,, these convergence part 222 correspondences are coupled to these joints 212, make terminal base 221 be placed in holding part 211.Because the aperture of these joints 212 is greater than the size of these convergence parts 222, so directions X and/or the motion of Y direction are carried out with respect to these joints 212 in these convergence parts 222, the degree of accuracy that is electrically connected of raising float connector 22 and outer welding system.

Please refer to Fig. 4, another embodiment's of the utility model hot-plug fan 3, its constituent components is all similar to hot-plug fan 2 to function, difference is: this hot-plug fan 3 comprises that more a fixing button 23A is arranged in the joint 212, and the convergence part 222A end of float connector 22A has a blocked part 228.The inside that fixing button 23A has a chute 231 and chute 231 has an overhead kick (seeing also Fig. 5 A and Fig. 5 B), and convergence part 222A is slidedly arranged in the chute 231, floats with single direction (for example Y direction) with respect to fan frame 21 in order to restriction float connector 22.In addition, the width W of terminal base 221 ' be slightly less than the width W of holding part 211 is used so that float connector 22 can be done floating of Z direction with respect to fan frame 21.

Float connector 22 is as described below with respect to the ralocatable mode of fixing button 23A.As shown in Figure 4, the chute 231 of fixing button 23A is for being oblong perforation and having an overhead kick, and the convergence part 222A of float connector 22A also correspondence is set to long cylinder and end has blocked part 228.Float connector 22A is slidedly arranged in the chute 231 by convergence part 222A, floats so terminal base 221 can be made the Y direction with respect to hot-plug fan 3.In addition, the width W of terminal base 221 ' be slightly less than the width W of holding part 211 is floated so terminal base 221 can produce the Z direction simultaneously with respect to hot-plug fan 3.Therefore, float connector 22A produces one dimension or two-dimentional floating simultaneously with respect to the fan frame of hot-plug fan 3, accurately is electrically connected with external system in order to guarantee hot-plug fan 3.

Below further specify the annexation of float connector 22A and fan frame 21 with Fig. 5 A and Fig. 5 B: Fig. 5 A shows that float connector is installed in the schematic representation of fan frame; And the part enlarged view of Fig. 5 B displayed map 5A.In Fig. 5 A, the convergence part 222A of float connector 22A is arranged in the chute 231 of fixing button 23A, further to combine with the joint 212 of fan frame 21.The end of convergence part 222A has blocked part 228, and is provided with overhead kick 232 in the chute 231.Shown in Fig. 5 B,, can guarantee float connector 22A the floating of Z direction, and avoid fixing button 23A to skid off and drop by joint 212 by the design of overhead kick 232 and blocked part 228.

Fig. 6 shows that another embodiment's float connector is installed in the schematic representation of fan frame.Present embodiment is different from the embodiment shown in Fig. 5 A and is: be provided with an overhead kick 232A in the joint 212 of fan frame 21, so the convergence part 222A of float connector 22A can be arranged in the joint 212.The design of the blocked part 228 by overhead kick 232A and convergence part 22A can be guaranteed float connector 22A floating in the Z direction.In the present embodiment, be provided with overhead kick 232A in the joint 212 owing to fan frame 21, so do not need fixing button can finish being connected of float connector and fan frame.

In all embodiments of the present utility model, the chute 231 of fixing button 23 and 23A is that a perforation pattern is with ccontaining convergence part 222 of difference and 222A.According to notion of the present utility model, this chute 231 also can be a groove kenel, as long as the convergence part is slidedly arranged on chute to reach floating of connector.

Again, in all embodiments of the present utility model, convergence part and fixing button are respectively the corresponding kenel of projection and perforation or groove.According to notion of the present utility model, the convergence part also can be the corresponding kenel that perforation or groove and fixing button are projection, as long as reach floating of connector.

In sum, a kind of hot-plug fan of the present utility model by connector the convergence part and the structure setting of terminal base, make connector make the one dimension direction or two-dimensional directional floats with respect to the fan frame.Compared with prior art, the utility model cooperates the splicing ear of external system, makes float connector do the adjustment of engagement positio and angle, accurately is electrically connected with external system so can guarantee hot-plug fan, and then promotes the reliability that is electrically connected.
