1222 are formed by sheet material portions cutting and bending hole 123 and upwards bending, and resistance film 1222 is integrally formed with main part 12, resistance
Glue groove 1221 passes through the gap of 12 upper end of main part to form two sections, which is located at 4 outside of plastic body, prevents pipe
When 1 injection molding of terminal, plastic cement, along 12 outside excessive glue of main part, generates flash, main part from the gap at 4 edge of plastic body
12 upper walls are further opened with an electroplating technology hole 121, prevent electroplating liquid medicine from entering inside circular tube terminal 1 and can not flow out, cause to be electroplated
Chemical reaction is generated between liquid medicine and circular tube terminal 1, corrodes circular tube terminal 1, and 14 rear upper side of wire interconnecting piece offers U-lag
141, convenient for that will be oriented in the U-lag 141, the conductive core of conducting wire and wire interconnecting piece 14 are welded by welding
It is connected together, ensures conductive between conducting wire and circular tube terminal 1.
14 tail portion of wire interconnecting piece of multiple circular tube terminals 1 is connect by pre- broken line 23 with same material strip 2 respectively, U-lag
141 opening directions are consistent with 2 surface of material strip, on material strip 2 between two neighboring circular tube terminal 1 be equipped with a positioning hole 21, adjacent two
The line feeder 22 of vertical tube terminal 1 is equipped between a location hole 21, when 2 width of anti-stopping materials strip is smaller, circular tube terminal 1 is because long
Weight balancing can not be reached between material strip 2, when 1 punch forming of circular tube terminal and the company of circular tube terminal 1 material strip being caused to pass through mold,
Circular tube terminal 1 tilts, and influences production efficiency.When the gap that the winding of circular tube terminal 1 is formed is larger, circular tube terminal 1 is being molded into
During type, a needle tubing need to be inserted into from U-lag 141, while injection mold uses slide block structure, prevents plastic cement from flowing to U-lag
141, influence conducting wire welding.
The beneficial effects of the utility model are：
1, contact flat spring 111 is concave arc, and flexible deformation occurs with to inserting when male terminal 3 contacts, is moved back to inserting male terminal 3
When going out, restore flexible deformation, not only improves circular tube terminal 1 and to inserting contact engaging and separating force and electric conductivity between male terminal 3, moreover it is possible to ensure
The durability of circular tube terminal 1 extends the service life of circular tube terminal 1.
2,13 diameter of forming part is more than 14 diameter of main part 12 and wire interconnecting piece, and forming part 13 fixes plastic body 4
In 13 outside of forming part, when preventing circular tube terminal 1 with being plugged to inserting male terminal 3, plastic body 4 is detached from circular tube terminal 1, causes to produce
Product fail.
3,13 diameter of forming part is more than 14 diameter of main part 12 and wire interconnecting piece, so as to fix plastic body 4
In 13 outside of forming part, when preventing circular tube terminal 1 with being plugged to inserting male terminal 3, plastic body 4 is detached from circular tube terminal 1, causes to produce
Product fail,
4, protrusion 131 sticks into inside plastic body 4, prevents circular tube terminal 1 from falling back to the back-end.
5, resistance film 1222 covers 12 endoporus of main part, and when preventing 1 injection molding of circular tube terminal, plastic cement is from plastic body 4
Along 12 inside excessive glue of main part at the gap at edge, flash is generated.
