Embodiment
This creation connector terminals 20 is to be assembled in the electric connector 1, and can electrically connect with a circuit board (figure slightly), and electric connector 1 can dock electric connector (figure slightly) with one and electrically connect.
See also Fig. 1 to shown in Figure 4, above-mentioned electric connector 1 includes an insulating body 10, several terminals 20 and a shielding casing 30, wherein this insulating body 10 is to make with the plastic material of insulation, these insulating body 10 rear end faces are provided with some slots 11, these slots 11 are corresponding with terminal 20, each each horizontal expansion of slot 11 upper ends forms a stopper slot 15, and this stopper slot 15 is roughly horizontal, and these terminals 20 can be installed in the slot 11 from these insulating body 10 rear ends.This insulating body 10 extends a hyoplastron 12 forward, and these hyoplastron 12 end faces and bottom surface are arranged with several and these terminal 20 corresponding grooves 13 respectively, and these grooves 13 are to extend toward insulating body 10 rear ends, and communicate with these stopper slots 15.
These terminals 20 are to form to have conductivity and flexible sheet metal one bending punching out, and can utilizing the technology of continuous punching press, equally spaced to stamp out one be row terminal 20, and via bending design, increase the dimensional stability of terminal 20.
Each terminal 20 is to comprise a base portion 21, a turning point 22, a contact site 23, a pin portion 24 and a reference column 25.This base portion 21 is the slots 11 that are embedded at these insulating body 10 rear ends, and these terminals 20 are contained in the insulating body 10.
This turning point 22 is to bend 90 degree by these base portion 21 upper limb places to form, and this turning point 22 is roughly horizontal, and corresponding with the stopper slot 15 of this insulating body 10, and this turning point 22 is to be placed in this stopper slot 15.
This contact site 23 is to be extended to form forward by this turning point 22, this contact site 23 is one to be free-ended microscler lamellar body, this contact site 23 is by this insulating body 10 and is contained in the groove 13 of this hyoplastron 12, this contact site 23 respectively is provided with a jagged fixed part 231 near the both sides of this base portion 21, this fixed part 231 is interfered the groove 13 in this hyoplastron 12, utilizes this fixed part 231 can make these terminal 20 stable being immobilizated in this electric connector 1.Electric connector 1 can contact with the corresponding position of above-mentioned butt joint electric connector by this contact site 23 and form electric connection.
