Abstract
The utility model discloses a fixedly-installed DC power supply socket, which can be used to solve the problems of conventional DC power supply sockets that the welding spots are easy to loosen and the pedestals are easy to vibrate. The DC power supply socket comprises a pedestal (1), a pin (2), a flat sheet (3), a bending sheet (4), and a reed (5). The fixedly-installed DC power supply socket is characterized in that the pedestal (1) is fixedly provided with a rear cover (6); the flat sheet (3), the bending sheet (4), and the reed (5) pass through the rear cover (6); an outer end surface of the rear cover (6) is provided with at least two positioning pins (7); the positioning pins (7) are cooperated with through holes in a circuit board. The fixedly-installed DC power supply socket is advantageous in that the installation is firm and reliable, and the plug can be easily inserted in the socket.
Description
Technical field
The utility model relates to a kind of DC power supply input interface element, is specifically related to a kind of firm DC supply socket of installing.
Background technology
The DC supply socket is usually used in power supply or the charging inlet of electronic product, generally match with the output plug of DC power source adapter, exported after with 220v alternating current step-down rectifier by power supply adaptor, by the DC supply socket on the electronic product to electronic product power supply or charging.Existing DC supply socket mainly is made up of pedestal, contact pin, plain film, bending and reed, and contact pin and plain film and bending fix, and an end of plain film, bending and reed stretches out outside pedestal, directly is fixed on the circuit board by Anping sheet, bending and reed.There is following technological deficiency in this DC supply socket: 1. in use, plug repeatedly plugs, and easily causes the solder joint of plain film, bending and reed loosening, loose contact.2. when plug plugged, pedestal produced vibration, and plug is difficult for being inserted in the pedestal fully.
The utility model content
Existing DC supply socket solder joint easily becomes flexible and pedestal produces the deficiency of vibration in order to overcome, and the utility model provides a kind of firm DC supply socket of installing, and the firm DC supply socket of this installation has solid and reliable and inserts the easy characteristics of plug.
The technical solution of the utility model is: a kind of firm DC supply socket is installed, comprise pedestal, contact pin, plain film, bending and reed, bonnet is fixedly arranged on the pedestal, plain film, bending and reed pass bonnet, at least be provided with two alignment pins on the outer face of bonnet, described alignment pin matches with through hole on the circuit board.
Described alignment pin is two and is the diagonal angle distribution.
Described alignment pin and bonnet are structure as a whole.
The utlity model has following beneficial effect: owing to take such scheme, when the plug plug, pedestal is difficult for shaking, and therefore, also can not make the solder joint of plain film, bending and reed loosening; In addition, pedestal is motionless, and is also very convenient when inserting plug.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is right views of Fig. 1.
1-pedestal among the figure, 2-contact pin, 3-plain film, 4-bending, 5-reed, 6-bonnet, 7-alignment pin.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
By Fig. 1 in conjunction with shown in Figure 2, a kind of firm DC supply socket is installed, comprise pedestal 1, contact pin 2, plain film 3, bending 4 and reed 5, bonnet 6 is fixedly arranged on the pedestal 1, plain film 3, bending 4 and reed 5 pass bonnet 6, at least be provided with two alignment pins 7 on the outer face of bonnet 6, described alignment pin 7 matches with through hole on the circuit board.Owing to take such scheme, when mounted, with in alignment pin 7 and the through hole that is inserted on the circuit board, weld plain film 3, bending 4 and reed 5 again, because alignment pin 7 is arranged, when the plug plug, pedestal 1 is difficult for shaking, and therefore, also can not make the solder joint of plain film 3, bending 4 and reed 5 loosening; In addition, pedestal 1 is motionless, and is also very convenient when inserting plug.
Described alignment pin 7 is two and is the diagonal angle distribution.Alignment pin 7 also can be three or four, and present embodiment mainly is in order to process with easy for installation.
Described alignment pin 7 is structure as a whole with bonnet 6.Adding man-hour, alignment pin 7 and bonnet 6 one-shot formings, easy to process.
Claims (3)
1. one kind firm DC supply socket is installed, comprise pedestal (1), contact pin (2), plain film (3), bending (4) and reed (5), it is characterized in that: pedestal (1) is gone up fixedly bonnet (6), plain film (3), bending (4) and reed (5) pass bonnet (6), at least be provided with two alignment pins (7) on the outer face of bonnet (6), described alignment pin (7) matches with through hole on the circuit board.
2. a kind of firm DC supply socket of installing according to claim 1 is characterized in that: described alignment pin (7) is two and is the diagonal angle distribution.
3. a kind of firm DC supply socket of installing according to claim 1 and 2 is characterized in that: described alignment pin (7) is structure as a whole with bonnet (6).
