When each contact 70 is contained in the corresponding contact accommodation hole 61, the first forward sweep 73 of contact 70, back-flexing part 74 and the second forward sweep 75 are positioned at the inside of contact accommodation hole 61, and the top 76Aa of the first flat spring part 76A and the second flat spring part 76B and 76Ba are outstanding from the top surface 60d of housing 60.And, when contact 70 is contained in the contact accommodation hole 61, the front surface of the first straight line portion 74d of the back-flexing part 74 of each contact 70 contacts with the retainer of each contact accommodation hole 61 surface 67, so just limited the travelling forward of back-flexing part 74 of each contact 70, and the inclination retainer of the rear surface of the second forward sweep 75 of each contact 70 and each contact accommodation hole 61 surface 68 contacts, thereby limited the motion backward of the second forward sweep 75 of each contact 70.In addition, the ledge 76Ac of each contact 70 and 76Bc enter in the groove 66 in two sidewalls that are formed on each contact accommodation hole 61, have so just limited head portion 76Ab and 76Bb at fore-and-aft direction and the range of movement that makes progress upward.And the electric conductor parts of the battery pack on portable phone one side can contact from above with 76Ba with the top 76Aa of each contact 70.
In addition, as shown in figure 10, under the state that does not have to connect in battery pack, the first flat spring part 76A of each contact 70 and the second flat spring part 76B are in free state, and the top 76Aa and the 76Ba of these flat spring parts are very outstanding from the top surface 60d of housing 60 like this.In addition, the first end 74a of each back-flexing part 74 and the second end 74b are separated from each other.
Then, when batteries charging, the electric conductor parts of battery pack are contacted with 76Ba with the top 76Aa of each contact 70, so as with these tops 76Aa and 76Ba to pressing down.Thereby when the ledge 76Ac on head portion 76Ab that is formed on these flat springs and the 76Bb and 76Bc moved downward by each groove 66, the first flat spring part 76A and the second flat spring 76B of each contact 70 were bent downwardly.As a result, the second forward sweep 75 of each contact 70 also is bent downwardly, and the back-flexing part 74 of each contact 70 and the part of the first forward sweep 73 also are bent downwardly.Therefore, the first end 74a of the back-flexing part 74 of each contact 70 and the second end 74b sliding contact, the electric conductor parts and the circuit board of battery pack are electrically connected mutually like this.Here, because the range of movement of ledge 76Ac and 76Bc is limited in the inside of groove 66, even so with a load from behind with the following first flat spring part 76A and the second flat spring part 76B that is applied to each contact 70 with a gradient (on the directions X in Figure 10) on, the first end 74a of the back-flexing part 74 of each contact 70 also can contact reliably with the second end 74b.In addition, when the second forward sweep 75 of each contact 70 is bent downwardly, when sliding on the inclination retainer surface 68 of rear surface at each contact accommodation hole 61 of the second forward sweep 75, limited the motion backward of the second forward sweep 75; Therefore, the first end 74a of the back-flexing part 74 of each contact 70 contacts mutually more reliably with the second end 74b.With during the second end 74b contacts, the rolling surface of these ends contacts with each other and short circuit at first end 74a; The result, two end 74a of back-flexing part 74 and the path between the 74b are electrically connected by a short path, so just shortened the circuit length in each contact 70, just be connected the length of leg piece 72 with the plate that 76Ba is attached thereto to circuit board from top 76Aa by the battery pack contact.Thereby, can reduce the electric conductor resistance in each contact 70.In addition, because sliding over each other, the rolling surface of two end 74a of the back-flexing part 74 of each contact 70 and 74b contacts, so contact pressure also increases; So, can increase contact reliability when in order to shorten the circuit length contact and to contact with each other.As a result, this electric connector can be suitable for use as a power supply connecting device, and this jockey is used for the circuit board on charger one side and is installed in the electrical connection of battery pack between mutually on portable phone one side.
In addition because contact 70 have two forward sweeps 73 with 75 with a back-flexing part 74 that is connected with 75 with these two forward sweeps 73, spring length is long, so can improve the durability of contact 70; And when keeping the connector lower height, the stroke of contact point 76Aa and 76Ba (displacement on the vertical direction just) also can increase.
In addition, when the first flat spring part 76A and the second flat spring part 76B are bent downwardly, in the second opening portion 76b of the part of back-flexing part 74 between the first and second flat spring part 76A and 76B, so just avoided the interference between the first and second flat spring part 76A and 76B and the back-flexing part 27.And, when as top 76Aa and 76Ba when the back-flexing part as a result that presses down 74 is bent downwardly, the part of back-flexing part 74 is positioned at the inside of first opening portion 77 of base portion 71, has so just avoided the interference between back-flexing part 74 and the base portion 71.
In addition, because the plate width of the first flat spring part 76A is different with the plate width of the second flat spring part 76B, so the spring constant of the first flat spring part 76A is also different with the spring constant of the second flat spring part 76B, when contacting with 76Ba with top 76Aa, battery pack B also can prevent outage like this.
