New Description: [New Technology Field] This creation department is about a cooling fan < power connector, especially a power connector in a hot fan, which is fastened to the housing of the cooling fan. On the end. This creation quotes domestic priority (application 曰: 95/06/20, application number: 95210776). [Prior Art] Electronic devices are equipped with different electronic components such as wafer servos, etc. However, with the rapid development of electronic related industries, electronic components 2 are becoming more and more hot, even due to chassis, etc. The closing factor makes the heat even better. In order to effectively dissipate heat in the environment outside the system to maintain the normal operation of the electronic components under the permissible temperature, it is usually attached to the f-board of the electronic components by means of a diverging fan, and (4) assists in heat dissipation, effectively avoiding electronic orders. The piece is overheated. However, each cooling fan needs to be electrically connected to the circuit board through the power connector to make it work. Please refer to the figure-- for the currently used cooling fan 10 a: the housing fan a of the cooling fan 1 〇a has a power connector 2 ◦ a on one side, which has an insulating housing 2 ia, four power terminals a and - ground terminals 2 3 a. The power terminals 2 2 & and the grounding terminal 2 3 a are elastically and protrudedly mounted on the insulating housing 2, and the power supply line 丄2 & The power connector 2 〇a can be electrically connected to the circuit board when the heat dissipation fan i 〇a is crimped to the contact of the circuit board (not shown). In addition, the elastic path of the grounding terminal 2 3 a is higher than the M309777 sub 2 2 a ' by which the grounding terminal 2 3 a is dusted to the contact of the circuit board to achieve the pre-grounding effect. However, the above-mentioned elastic power terminal 2 2 a and the grounding terminal 23 3 a are permanently crimped or have a lack of elastic fatigue under frequent use, which inevitably causes poor contact with the circuit board, especially the ground terminal 2 3 & When the elastic stroke is lower than the power terminal 2 2 a, it is easy to form the power terminal 22a to contact the circuit board first, and the grounding effect is deficient, thereby further damaging the cooling fan 10 a Or electronic parts and so on. One reason is that the creator feels that the above-mentioned lack of improvement is due to the spirit of excellence, and proposes a design that is reasonable in design and effective in improving the above-mentioned deficiency. [New content] The purpose of this creation is to provide a power supply connection for the cooling fan, which has a structure of error-proof insertion and a better elastic buckle, and a power supply and a grounding plate made of a metal plate member. It is not easy to deform and wear. For the purpose of the above, the present invention provides a power supply connection of a cooling fan, which is coupled to a housing of the cooling fan, and a mounting portion is formed at one end of the housing, and the power connector includes a The insulative housing has a top plate and a side plate connected to the side edge of the top plate. The two sides of the inner end edge of the top plate are provided with a latching portion for snapping on the mounting portion, and the insulating housing faces outward. One of the power supply plates has a first main body portion protruding from the recess, and a first terminal extending inwardly from one end of the first main body portion and exposed And a first pin end extending downward from one end of the first body portion M309777 to be fixed in the insulating housing; at least one ground plate having a second body portion protruding from a second terminal end extending inwardly from one end of the second body portion and exposed outside the recess, and a second pin end extending downward from one end of the second body portion to be fixed to the recess Inside the insulating housing; a spacer is protruded in the recess of the insulating housing Segments power plate and a ground plate sheet; and a slot provided on the side of the top plate 'which so - with the locking portion resiliently snap-fitted on the erected portion. • The beneficial effect of the original power connector is that the power supply and the grounding plate made of the metal plate have the characteristics of being difficult to be deformed and wear-resistant, and a spacer is arranged between the power supply and the ground plate. To prevent, the device, the power connector, and one side of the top plate are set to one: ^,. The preferred embodiment of the present invention will be described in detail below with reference to the preferred embodiment of the present invention. This creation, not the right scope of this creation [Embodiment] See the second and third diagrams of a fan power connector, the power supply is connected to the second, the creation department provides a kind of cooling fan 50 housing 5 1 - On the side.

The 忒 insulative housing 1 is slidably attached to the erecting portion 51 1 , and the private board < 2 Ό and the grounding strip 3 Q are housed in the insulating housing 10 , and The power cord group 5 3 is electrically connected. • The one side of the edge housing 1 〇 can be recessed with two recesses i i ′ to accommodate the power strip 2 接地 and the ground plate 3 〇. The insulation A and the body 1 have a top plate ii, and a side plate 12 connected to a side edge of the top plate 1 1 , wherein the recess 13 is recessed in the top plate ii and the side plate 12 Between the inner edge and the bottom edge of the recess 13 is a plurality of mutually corresponding first-fixing slots and second fixed slots 32. In this case, a latching portion 14 and 14 are respectively protruded from opposite sides of the inner edge of the top plate ii of the housing 1 Q, so as to be engaged with the engaging hole 5 of the mounting portion 5 The top plate 1 1 and the side plate 1 2 are respectively in the same plane as the side surface of the casing 5 _. In a further detailed description, in the present invention, a slot 1 丄i is formed on a side of the top plate 1 1 of the insulating housing i , so that the latching portion 4 of the side is elastically latched to the erecting portion 511 . on. Wherein the buckle parts '4, 14 can be fixed, or both can have a spring arm, or can be fixed, and the other arm; the creation only uses the buckle portion 14, the system has a bullet The characteristics of the arm type are elastically fastened to the engaging holes 5丄2 of the casing 5 i, and the other fastening portions 14 are fixed as an example, so that the buckle portion 14 is utilized with 8 M309777] The gap of 1 1 provides the entire buckle portion 14 , and a portion of the elastic outer portion has another elastic portion. In addition, a spacer block 33 3 is protruded from the recess 2 of the insulating housing i , to partition the power board 舁 the grounding plate 30, and the spacer block 133 has a foolproof Guide 'to avoid the occurrence of mis-insertion. 5H and other power supply board pieces 20 have a first main body portion 2丄 to protrude = the first terminal 2 2 of the recess i 3 extending inwardly from the first main body portion 2 and Exposed to the outside of the pocket 丄3, and a first pin end 2 3 extending downward from the bottom end of the first body portion 2 1 is fixed in the rim: edge housing 10 . However, the first terminal 2 2 is inserted into the phase; the first fixing groove i 3 丄 and protrudes from the first fixed temple 13 1 of the cavity 3 to be connected with the power line group 5 3 The connection, that is, the power cord set 5 3 :!: is connected to the first terminal 2 2 , and the first pin end 2 3 is formed with a barb on one side to interfere with the fixed insertion in the corresponding second Fixed slot 3 2 inside. 9) The grounding plate 30 has a second main body portion 31 formed in the recess 13 and disposed on one side of the grounding plate 3, and the second main portion 3 1 a second terminal 3 2 extending inwardly and exposed to the outer portion of the 181 and a first pin end 33 extending downward from the bottom end of the second body portion 31 to be fixed to the insulation Inside the housing i 0 . In the present invention, the first body portion 31 of the board 30 is also larger than the first body portion 2 1 of the power board so that the ground plate 3 protrudes from the power board 2 0.
