Abstract

The utility model relates to a terminal structure, which is provided with a back section plate-shaped fixing plate for connecting wires and a tubular clamping pipe for clamping and putting an inserted complementary terminal in electrical property contact in an integral punching molding mode, wherein, the clamping pipe is provided with three slotted holes with equiangular intervals and unequal length, and thus, three contact spring plates with unequal length are formed in a spacing molding mode by the three slotted holes. Not only the contact area of each contact spring plate is enlarged, but also a stronger and stabler clamping force is produced by the terminal because of the complementary supplement of the long contact spring plate which has high elasticity and low tightness and the short spring plate which has low elasticity and high tightness. Thus, the electrical property contact effect between the terminal and the complementary terminal is enhanced to improve the stability of the telecommunication transmission quality of the terminal.

Therefore and can't effectively embed and hold the insulation outer tube and loosening or even come off in complementary terminal 2 Plug Actions easily in addition, the stator 10 of this kind terminal 1 is a straight plate face.

Main purpose of the present utility model provides a kind of energy can strengthen the terminal structure that electrical property contacts effect with high resiliency with high tightness clamping contact force simultaneously, it mainly makes each contact flat spring of terminal grip tube be shaped to the kenel that length all has, can utilize the characteristic of the high resiliency of long contact flat spring and low tightness simultaneously and adapt to the characteristic of the low elasticity of complementary terminal vary in diameter and collocation utilization short contact shell fragment and high tightness and can grip complementary terminal, therefore can strengthen this terminal and contact effect with electrical property between complementary terminal, with the reduction impedance, and the telecommunication transmission quality of raising connector.

Another purpose of the present utility model provide a kind of can guarantee terminal unlikely in its insulation outer tube the loosening or terminal structure that comes off, mainly make the stator both sides elongation moulding of terminal back segment go out protruding wall, can more effective embedding promote stability of structure with being held in the insulation outer tube wall.

The utility model is achieved in that it has for the tabular stator of back segment that is connected lead with monometallic lamellar body one punch forming, and the tubulose grip tube that supplies clamping and the electrical property contact complementary terminal of inserting, wherein grip tube is provided with axial a plurality of slotted holes of equi-angularly space and uses to separate and is formed with a plurality of contact flat springs, and the equal indent of each contact flat spring appropriate location and be formed with less internal diameter; It is characterized in that: wherein the grip tube of terminal is provided with the slotted hole of three road unequal lengths, and uses the contact flat spring that correspondence separates out three unequal lengths.

Wherein two road slotted hole development lengths in the three road slotted holes are longer, and the development length of another slotted hole is then shorter.

Wherein the both sides of terminal stator in addition up elongation moulding the protruding wall of side is arranged.

Characteristics of the present utility model are that wherein grip tube is provided with equi-angularly space and does not wait three slotted holes of length, use to separate and form three contact flat springs that do not wait length, so not only each contact flat spring can increase with respect to the contact area of complementary terminal, and more can be by the tool high resiliency, the long contact flat spring and the low elasticity of low tightness characteristic, the complementation of complementing each other of the short contact shell fragment of high tightness, this terminal decapacitation is produced outside the stronger and firm chucking power, more can allow the little deviation of the diameter dimension of complementary terminal or direction of insertion and still can be gripped, can strengthen this terminal and contact effect with electrical property between complementary terminal and reduce impedance, with the stability of the telecommunication transmission quality that improves this terminal.
