Description
Technical field
The present invention relates to short circuit connector, it is suitable for installing on inverter board, and this inverter board constitutes the power circuit of backlight of the light source of the liquid crystal panel that forms PC for example etc.
Background technology
Backlight for the light source of the liquid crystal panel that forms PC etc. as shown in figure 11, uses the device of arranging a plurality of cathode fluorescent tubes (CCFL pipe) 1.This CCFL pipe 1 has needle electrode 2,2 at two ends, is connected separately on the inverter board (printed circuit board (PCB)) 3 that constitutes power circuit.With each CCFL pipe 1 electric connector that is connected electrically on each inverter board 3, use for example disclosed connector in patent documentation 1 or patent documentation 2 etc.Omission is to the explanation of its details, and this connector is made of following part: accommodate two contact pin type contacts side by side in insulation shell, and its two reeds portion soldering is carried out the male connector 4 of mounted on surface on inverter board 3; Be housed in female connector 6 in the insulation shell side by side with a pair of socket contact that will be connected in two wires, 5,5 ends, the other end of two wires 5,5 is connected with the needle electrode 2,2 of CCFL pipe 1, make female connector 6 and 4 chimeric connections of male connector, each CCFL pipe 1 is electrically connected with an inverter board 3 separately.
Yet in the foregoing circuit structure, the CCFL pipe 1 to uses an inverter board 3 and a pair of male connector 4, female connector 6, therefore, needs a plurality of inverter board 3 and a plurality of male connector 4, female connector 6 on the whole, and cost uprises.In addition, since the situation of electric wire 5,5 solderings use on the needle electrode 2,2 of each CCFL pipe 1 is more, thereby exist the soldering operation to need the problem of labour and time.
In recent years, as this backlight, use external electrode fluorescent lamp pipe shown in Figure 10 (EEFL pipe) 10 to replace existing C CFL pipe 1.This EEFL pipe 10 has the structure that coats the outer electrode 11,11 that covers shape at the two ends of the slender glass tube of having enclosed Ne gas, Ar gas etc., and Figure 10 represents to use this EEFL pipe 10 to constitute the example of the power circuit of backlight.
In the circuit structure that uses EEFL pipe 10, each EEFL manages 10 the parallel circuits that is connected to, even under the situation of the backlight of arranging a plurality of EEFL pipes 10, also only need two inverter board 3, thereby cost advantage (cost merit) uprises.The outer electrode 11,11 of each EEFL pipe 10 releasably embeds and is connected in the terminal metal piece 14,14, and described terminal metal piece 14,14 is connected electrically on the electroconductive member pattern 13,13 of relaying substrate 12,12 side by side.In addition, two wires 15,15 are connected electrically on the electroconductive member pattern 13,13 by soldering or terminal.By forming such circuit structure, assembling operation and cost advantage improve, and, the many advantages such as become easily of the replacing operation with EEFL pipe 10.
In the foregoing circuit structure, two wires 15,15 that utilize parallel circuits to be connected with the electrode 11,11 of each EEFL pipe 10, be connected with inverter board 3,3 respectively respectively, therefore, in fact as long as use the electric connector of a utmost point that one wire 15 is connected on the inverter board 3.But, when the electric connector that uses a utmost point is connected a wire 15 on the inverter board 3, taking place can to cause suddenly that backlight work is bad under the situations such as connector loose contact and electric wire disconnection, existing problems aspect reliability.Therefore, as shown in figure 10, utilize parallel circuits to be connected with each inverter board 3, can prevent that then above-mentioned work is bad, improve reliability with two wires 15,15 that the electrode 11,11 of each EEFL pipe 10 is connected if make.

Summary of the invention
The object of the invention is to provide a kind of connector that two wires 15,15 in the circuit structure shown in Figure 10 are connected on the inverter board 3 of being suitable for.Particularly, be connected the female connector on the end of two wires 15,15, directly utilize the existing female connector 6 that is connected with the end of two wires 5,5 in the circuit structure of existing use cathode fluorescent tube shown in Figure 11 (CCFL pipe) 1, to improving, thereby provide the short circuit connector that the connection reliability with respect to inverter board 3 is improved with these female connector 6 chimeric male connectors that are connected 4.
To achieve these goals, short circuit connector of the present invention is the male connector with contact of short-circuit structure, and the contact pin type contact that is housed in the two poles of the earth in the insulation shell has: two contact pin portions, towards the peristome almost parallel of described shell give prominence to; And two reed portions, itself and this corresponding setting of two contact pins portion, stretch out also soldering on printed circuit board (PCB) from described shell, the mid portion of described contact pin portion and described reed portion connects as one by brace, it is characterized in that, the a pair of socket contact that is connected in two wire ends is housed in female connector in the insulation shell, inserts described peristome, described a pair of socket contact is with described two contact pin portion is chimeric is connected.
Described two reed portions stretch out agley towards lateral outer side each other, and its soldering partly is equipped on two jiaos of rear end, bottom of described shell.
Two jiaos that preferably constitute in the bottom front of described shell are provided with reinforcement.
In addition, the rear wall of described shell is provided with and makes the through hole that described two contact pin portions connect and the embeded slot of the described brace of chimeric maintenance, two contact pin type contacts constitute the described contact of the short-circuit structure of one by described brace, be assembled in the described shell with stable attitude.
As described above, short circuit connector of the present invention, has the short-circuit structure that the contact pin type contact with the two poles of the earth links into an integrated entity by brace, therefore, even take place with the chimeric contact pin type contact that is connected a side on the loose contact of socket contact, the perhaps cut-out of generation and this socket contact wire connecting also can be by preventing that with chimeric socket contact that is connected in the opposing party's contact pin type contact and electric wire work is bad.And, and by printed circuit board (PCB) the reed portion of described each contact pin type contact is carried out the situation that short circuit is connected and compare, not to problems such as the load of figure and figure fractures, so, also very good aspect reliability.
In addition, because having the contact of the contact pin type contact at the two poles of the earth itself is structure as a whole, therefore be easy to make the soldering of the reed portion of each contact pin type contact partly to be configured in on the one side, can realize stable soldering, operation is good, and can finish assembling by a stroke, reduce cost insulation shell.
In addition, when as mentioned above with short circuit connector of the present invention and existing female connector 6, use is when connecting backlight of arranging external electrode fluorescent lamp pipe (EEFL pipe) 10 and constituting and the inverter board that constitutes its power circuit, then can reduce the use number of inverter board and connector, with use existing female connector 6 to reduce cost to combine, can increase substantially assembling operation and cost advantage.
