Embodiment
Reach technological means and the effect that predetermined purpose is taked for further setting forth the present invention, see also following about detailed description of the present invention and accompanying drawing, believe purpose of the present invention, feature and characteristics, go deep into and concrete understanding when getting one thus, yet appended graphic reference and the explanation usefulness of only providing not is to be used for the present invention is limited.
See also Fig. 1 to shown in Figure 5, be first embodiment of the invention.The present invention is a kind of stationary installation that is used for expansion board.This stationary installation comprises a casing 1 and a metal crimp product 2.
In the present embodiment, the pin-jointed structure of metal crimp product 2 has two portions 23 of picking up the ears.Portion's 23 one of picking up the ears are connected in an end of base plate 20.The portion 23 of respectively picking up the ears is provided with a pivot hole 231.The elastic lock structure of metal crimp product 2 has an elastic arm 24 and a latch part 25.The bottom one of elastic arm 24 is connected in the other end of base plate 20, and towards outer incline, and elastic arm 24 has a pulling part 241 along the longitudinally of base plate 20 on the top of elastic arm 24.Latch part 25 one are connected in the top of elastic arm 24.Latch part 25 has folding part 252 on an inflexed part 251 and, and extend to this pin-jointed structure from the top of elastic arm 24 inflexed part 251, and 251 extensions make progress from the inflexed part to go up folding part 252.In addition, side plate 21 has a stop section 212, and stop section 212 is positioned at the inboard of the last folding part 252 of latch part 25, with folding part on the block 252, thereby limits the scope of activities of this elastic lock structure.
The pick up the ears pivot hole 231 of portion 23 is articulated in protruding axle 13 respectively, makes this pin-jointed structure be articulated in casing 1, thereby makes metal crimp product 2 be articulated in casing 1 and can not come off from casing 1.
Expansion board 3 can be a display card or a sound card etc.Expansion board 3 has a circuit board 30 and a carriage 31.Circuit board 30 has an electrical contacts 301 and a connectivity port (figure slightly).Carriage 31 has a body 311, a kink 312 and an inserted sheet 313.Kink 312 is positioned at the upper end of body 311 and is provided with a breach 314.Body 311 is perpendicular to kink 312 and be provided with the connectivity port of a connecting hole (figure slightly) corresponding to circuit board 30.Inserted sheet 313 is positioned at the lower end of body 311.
The motherboard of this electronic equipment has several connectors.When expansion board 3 was mounted, at first, the electrical contacts 301 of the circuit board 30 of expansion board 3 was inserted in one of them corresponding connector, and the inserted sheet 313 of the carriage 31 of expansion board 3 is located in the jack 12 of casing 1.Simultaneously, the body 311 of carriage 31 is corresponding to the slotted eye 11 of casing 1, and the kink 312 of carriage 31 is overlapped on the bearing and leaning portion 10 of casing 1.Then, the base plate 20 of metal crimp product 2 is crimped on the kink 312, and latch part 25 snap closes are in colluding sheet 14, make metal crimp product 2 the elastic lock structure dividually snap close on casing 1.So, the kink 312 of the carriage 31 of expansion board 3 is held between the bearing and leaning portion 10 and metal crimp product 2 of casing 1 reliably, with the electrical contacts 301 of the circuit board 30 of guaranteeing expansion board 3 and the electrical connection between this corresponding connector.
In addition, the spacer 202 of base plate 20 is inserted in the pilot hole 101 of bearing and leaning portion 10, makes that the position of base plate 20 is accurate, and makes metal crimp product 2 more firm.The lappet 22 of metal crimp product 2 also is buckled on the body 311 of carriage 31 of expansion board 3, makes carriage 31 more firm.The kink 312 of the carriage 31 of the shell fragment 201 contact expansion boards 3 of base plate 20 is to obtain the effect of ELECTROMAGNETIC OBSCURANT.
Moreover by the characteristic of this sheet metal, the volume of metal crimp product 2 is little and holding force is big, and the space that makes metal crimp product 2 take in the casing 1 is little, and makes metal crimp product 2 can fix most expansion boards 3 reliably in casing 1.
The bearing and leaning portion 10 of casing 1 can further be provided with a screw 102, and the base plate 20 of metal crimp product 2 can further be provided with a perforate 203.One screw 4 passes perforate 203.The head crimping carriage 31 of screw 4, and breach 314 and interlocking are passed in screw 102 in the threaded portion of screw 4.Therefore, the present invention's the stationary installation that is used for expansion board also allows fixedly expansion board 3 of screw 4.
During desire dismounting expansion board 3, the pulling part 241 of this elastic lock structure is pulled, and makes 25 disengagings of latch part collude sheet 14, thereby can make this elastic lock structure break away from casing 1.
The stationary installation that is used for expansion board of the present invention with metal crimp product 2 fixedly the kink 312 of the carriage 31 of expansion board 3 in the bearing and leaning portion 10 of casing 1.The dismounting of expansion board 3 need not any instrument and screw, and therefore, the dismounting of expansion board 3 is more convenient and rapid.In addition, metal crimp product 2 can not come off from casing 1, therefore, does not cause the malfunctioning doubt of running of this electronic equipment.Moreover expansion board 3 need not to use screw, makes the cost of zero element of this electronic equipment reduce.
See also Fig. 6 to shown in Figure 10, be second embodiment of the invention.Main difference between second embodiment and first embodiment is its elastic lock structure.In a second embodiment, casing 1 is provided with a bonnet lock hole 15, and this elastic lock structure has an elastic arm 26, and elastic arm 26 has a pulling part 261 and a protuberance 262.Protuberance 262 snap closes of elastic arm 26 in the bonnet lock hole 15 of casing 1, make this elastic lock structure by snap close on casing 1, thereby make metal crimp product 2 reliably the kink of the carriage of crimping one expansion board (figure slightly) on the bearing and leaning portion 10 of casing 1.
During desire dismounting expansion board 3, the pulling part 261 of this elastic lock structure is pulled, and makes protuberance 262 withdraw from bonnet lock hole 15, thereby can make this elastic lock structure break away from casing 1.
So, by the stationary installation that is used for expansion board of the present invention, have characteristics described as follows:
1, the pin-jointed structure of this metal crimp product, base plate and elastic lock structure be articulated in respectively an electronic equipment casing, this expansion board of crimping carriage kink on the bearing and leaning portion of this casing and snap close on this casing, make that this expansion board can more convenient ground and promptly be fixed in or be disassembled casing from this electronic equipment.
2, the pin-jointed structure of this metal crimp product is articulated in this casing, and therefore, this metal crimp product can not come off from this casing, makes the dismounting of this expansion board can not cause the running of this electronic equipment malfunctioning.
3, fix this expansion board and need not use screw, make the cost of part of this electronic equipment reduce.
4, this metal crimp product is formed by a sheet metal, therefore, the volume of this metal crimp product is little and holding force is big, and the space that makes this metal crimp product take in this casing is little, and makes this metal crimp product can fix most expansions reliably to be stuck in this casing.
In sum, the present invention meets the important document of application for a patent for invention fully, so file an application according to Patent Law in the whence.
The above, it only is the detailed description of specific embodiments of the invention and graphic, be not in order to restriction the present invention and feature of the present invention, such as have in the affiliated technical field and know the knowledgeable usually, modify or variation along the equivalence of doing according to spirit of the present invention, all should be included in the claim of the present invention.
