Abstract
The utility model provides a switch. The switch comprises a casing, and a motherboard and expansion daughter boards which installed inside the casing. A sidewall of the casing is provided with ports for the expansion daughter cards inserting into the casing. A bottom wall of the casing is provided with metal supports which are used for installing and bearing the expansion daughter cards. The casing is connected with a grounding terminal of a power supply. The expansion daughter cars are provided with metal sheets, and when the expansion daughter cards are inserted into the casing via the ports, the metal sheets are connected with the metal support, and thus static electricity of the expansion daughter cards is discharged, and the static electricity is prevented from transmitting to the mother board and affecting the motherboard. As a result, the switch supports the expansion daughter cards to be capable of free plugging when the switch is powered on.
Description
[technical field]
The utility model relates to a kind of switch, especially the structure of the expansion subcard of switch.
[background technology]
Switch is a kind of network equipment for signal of telecommunication forwarding, and it can provide the pathway for electrical signals that exclusively enjoys for any two network nodes of access switch.
Generally, the Ethernet switch product also can increase a plurality of 10000M network interfaces on the basis of 24 or 48 original 1000M network interfaces.The 10000M network interface is integrated on the expansion subcard, and the expansion subcard can be chosen in the switch casing and freely plug, and realizes linking to each other or disconnecting with mainboard.But only freely plugging of expansion subcard occurs in the situation of switch outage, when needs are loaded onto expansion subcard or unloading expansion subcard for switch, need to cut off the power supply for switch.Because switch is in the situation of energising, staff is taken the expansion subcard to insert to link to each other with mainboard in the casing or is extracted in casing when expanding subcard, static on the person can pass on the mainboard, cause static mainboard to be produced the situation of impacting even occurring burning out, especially in the winter of drying, the static on the person is larger.
[utility model content]
The technical problem that the utility model need solve is to overcome above-mentioned deficiency, and a kind of switch that can prevent static is provided.
For solving above-mentioned technical problem, the utility model has designed a kind of switch, comprise casing, be installed on mainboard, expansion subcard in the casing, the sidewall of casing is provided with for the port in the expansion subcard insertion casing, also be provided with the metallic support that is attached thereto and is used for installation and supporting expansion subcard on the diapire of casing, described casing connects with the earth terminal of power supply, described expansion subcard is provided with sheet metal, when the expansion subcard is in port inserts casing, sheet metal links to each other with metallic support, thereby is expansion subcard static electricity discharge.
Further improve as the utility model, described sheet metal is located at respectively on the left side edge and right side edge of described expansion subcard, described metallic support comprises left metallic support and right metallic support, be equipped with draw-in groove on left metallic support and the right metallic support, the left side edge of described expansion subcard and right side edge snap in respectively in the draw-in groove of left metallic support and right metallic support.
Further improve as the utility model, described sheet metal is bar shaped, and the left side edge of described expansion subcard and right side edge are equipped with 2 sheet metals that are separated from each other.
Expansion subcard of the present utility model is provided with sheet metal, when staff is taken the expansion subcard to be inserted in the casing or extract the expansion subcard in casing, static on the person can pass on the casing by sheet metal and metallic support, and casing links to each other with the earth terminal of power supply, thereby electrostatic leakage is arrived the earth, prevent that static from passing on the mainboard, exerts an influence to mainboard.Thereby the utility model exchange function support expansion subcard freely plugs in the situation of switch energising.
[description of drawings]
Fig. 1 is the internal structure schematic diagram of the utility model embodiment switch;
Fig. 2 is the structural representation that the utility model embodiment expands subcard;
Fig. 3 is the structural representation of the utility model casing.
[embodiment]
The utility model is described in further detail below in conjunction with drawings and embodiments.
As shown in Figure 1, a kind of embodiment of the utility model switch, this switch comprise casing 1, mainboard 2 and 2 expansion subcards 3 are installed in casing.Each expands the network interface that is integrated with 2 10000M on the subcard 3.Expanding subcard 3 can freely plug in that casing 1 is interior, links to each other with mainboard 2 or is separated from each other.
As shown in Figure 3, be provided with the port one 0 that inserts in the casings for expansion subcard 3 at the sidewall of casing 1, also be provided with on the diapire of casing the metallic support 11 of expanding subcard is installed, metallic support and casing diapire are fixedly linked.In the utility model, casing connects with the earth terminal of exchanger power.
Each expand subcard 3 by about two metallic supports 11 support and fix, its middle left and right metallic support is equipped with draw-in groove 110.When expansion subcard 3 inserts casing 1 when interior by port one 0, the edge, the left and right sides of expanding subcard 3 snaps in the draw-in groove 110 of left and right sides metallic support, inserts in the casing 1 along the direction of draw-in groove 110, links to each other with mainboard 2.
As illustrated in fig. 1 and 2, be equipped with sheet metal 30 on the left and right edge of described expansion subcard 3, and, being equipped with respectively 2 sheet metals that are separated from each other 30, sheet metal 30 can be fixed in by the mode of welding on the expansion subcard 3.Sheet metal 30 is bar shaped, and in expansion subcard 3 insertion draw-in grooves 110, along the direction of inserting, bullion sheet 30 contacts fully with metallic support 11 and links to each other.
When staff is taken expansion subcard 3 to be inserted in the casing 1 to link to each other with mainboard 2, or expansion card 3 is extracted expansion 3 cards when linking to each other with mainboard 2, people's one contact expansion subcard 3, static with it can pass to casing 1 by sheet metal 30 and metallic support 11, and casing 1 links to each other with the earth terminal of power supply, thereby electrostatic leakage to the earth, is prevented that static from passing on the mainboard, exerts an influence to mainboard.Thereby the utility model exchange function support expansion subcard freely plugs in the situation of switch energising.
Above-described only is execution mode of the present utility model; should be pointed out that for the person of ordinary skill of the art at this, under the prerequisite that does not break away from the utility model creation design; can also make improvement, but these all belong to protection range of the present utility model.
