Abstract
The utility model discloses a power supply unit used on a fire-fighting product, which includes a terminal and a spring leaf with elasticity and electrical conductivity. Buckling sheets in pair are arranged on the spring leaf, the tops of the two buckling sheets are connected to form a connecting sheet, the connecting sheet extends upwards in an oblique direction and forms a bending sheet; and the terminal includes a substrate, lugs matched with the buckling sheets in shape are projected out from the substrate, and the lugs and the bucking sheets are in tight fit. When the product is installed, an upper housing of the fire-fighting product is needed to be inserted on a base, and grooves on the spring leaf and arc outer projected parts of the terminal are clamped and connected fixedly at the moment. The clamping connection of the spring leaf and the terminal is firm and very reliable, the impact resistance and the shock resistance of the product are improved, the reliability of power supply is strong, and the power supply unit is prevented form falling off during transportation and use.
Description
Technical field
The utility model relates to the power supply jockey on a kind of fire product.
Background technology
In the fire product of various models, products such as its module, hand newspaper and button are made up of upper casing and base two parts, and base is fixed on the metope embedded box, and circuit board is fixed on upper casing, and base is provided with the binding post to this circuit board power supply simultaneously.Upper casing and base are corresponding is connected after, when product entered operating state, product was solid and reliable under conditions such as collision, vibration and impact, otherwise became flexible opening circuit of can causing powering.The present connect-disconnect structure that product adopted is by the frictional force between plane and the plane, upper casing is fixed on the base, upper casing impacts easily under vibration or percussion, the power supply jockey tractive under the effect that comes off of upper casing that is connected between upper casing and the base can't disconnect, and product is cut off the power supply can't operate as normal.
The utility model content
In view of this, the technical problems to be solved in the utility model is the electric supply installation that uses on a kind of fire product is provided, and makes between the upper casing of product and the base power supply stable.
For solving the problems of the technologies described above, the technical solution of the utility model is achieved in that the electric supply installation that uses on a kind of fire product, comprise terminal and shell fragment with elasticity and conductivity, described shell fragment is provided with paired fastening piece, brace link to each other to be formed on the top of two fastening pieces, and brace extends obliquely upward curved tabs is set; Described terminal comprises substrate, and two lugs that adapt with described fastening piece shape of this substrate upper process closely cooperate between described lug and the described fastening piece.
On described fastening piece, be provided with groove.
The end of described two lugs is the opening to outer arcuate, and this arc male part is provided with described groove corresponding matching just.
The technique effect that the utility model reaches is as follows: when fire product is installed, upper casing need be plugged on the base, the groove on the shell fragment and the arc male part of terminal connect and fix just at this moment.Shell fragment and terminal connect and fix and very firm, improved the ability of the shock resistance and the vibration of product, power supply reliability is strong, prevent the transportation and use in come off.
Description of drawings
Fig. 1 is the structural representation of the utility model electric supply installation.
Embodiment
As shown in Figure 1, be the electric supply installation that uses on a kind of fire product of the utility model, comprise shell fragment 2 and terminal 1 with elasticity and conductivity, described shell fragment 2 is provided with paired fastening piece 21, the top of two fastening pieces 21 links to each other and forms brace 22, brace 22 extends obliquely upward curved tabs 23 is set, and curved tabs is provided with curvature 231 so that be connected with the upper casing of product.On described fastening piece 21, be provided with groove 211.
Described terminal 1 comprises substrate 11, and two lugs 12 that adapt with described fastening piece 21 shapes of these substrate 11 upper process closely cooperate between lug 12 and the described fastening piece 21.The end of two lugs 12 is the opening to outer arcuate, these arc male part 121 lucky and described groove 211 corresponding matching settings.
The upper casing of shell fragment 2 and fire product is connected for compressing, and base is fixed with terminal 1, when product is installed, needs this upper casing is inserted on its base, and the arc male part 121 of groove 211 on the shell fragment 2 and terminal 1 connects and fixes just and be very firm at this moment.Between shell fragment 2 and the terminal 1 connect and fix and very firm, improved the ability of the shock resistance and the vibration of product, power supply reliability is strong, prevent the transportation and use in come off.
The above is preferred embodiment of the present utility model only, is not to be used to limit protection range of the present utility model.
