Abstract
The utility model discloses a terminal comprising a contact part and a wire pressing part. The contact part comprises a horizontal segment. One end of the horizontal segment is connected with the wire pressing part, and the other end of the horizontal segment is connected with an inclination segment which is arranged to be upwardly inclined towards direction of the wire pressing part. A supporting segment is arranged between one end, which is away from the horizontal segment, of the inclination segment and the horizontal segment in an abutting way. The supporting segment comprises a vertical part. One end of the vertical part is connected with the inclination segment, and the other end of the vertical part extends towards the direction of the horizontal segment so that a bifurcate elastic supporting leg is formed. The lateral projection view of the supporting segment presents to be shaped like a Chinese character "ren". When an inserting pin extrudes the upper end part of the inclination segment, the supporting segment is pressed by force. The bifurcate elastic supporting leg deforms so as to supply elastic supporting force to the upper end part of the inclination segment, and the inserting pin is firmly connected in the abutting way. Length of the elastic supporting leg is controlled according to the proportion of the vertical part in the supporting segment, and the optimal proportion is arranged so that the maximum deformation of the contact part can be controlled via the vertical part, elastic intensity can be controlled according to length of the elastic supporting leg, elastic force is dispersed by the elastic supporting leg, and thus the fatigue service life is longer.
Description
Technical field
The utility model relates to a kind of electrical fitting, and more particularly, it relates to a kind of terminal.
Background technology
Terminal is a kind of element that is mainly used in transmitting the signal of telecommunication or conduction.
At present, the terminal on market, it comprises contact site for electrically contacting with contact pin and for the line ball portion with conductor compression jointing.This terminal, its contact site is bent to the reed structure of obtuse triangle conventionally by sheet material, described contact site comprises horizontal segment, outer incline section and tilted section, the junction of outer incline section and tilted section forms abutting part, in use, terminal is arranged in the housing of corresponding connector, the inwall butt of abutting part and housing, while being connected with contact pin, contact pin extruding abutting part, insert between abutting part and housing, and be subject to the elastic force effect of reed structure by butt, reed structure deformation, yet the fatigue life of the reed structure of obtuse triangle is not long, special when exceeding reed structure largest deformation scope, as contact pin is broken curved, or in plug process, the angular deflection amount of contact pin is excessive, can make the fatigue of reed structure further aggravate, shorten fatigue life, cause terminal in follow-up use can not with the abundant butt of contact pin, cause loose contact, affect the useful life of terminal.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of fatigue life long terminal.
For achieving the above object, the utility model provides following technical scheme: a kind of terminal, comprise contact site and line ball portion, described contact site comprises horizontal segment, one end of described horizontal segment is connected with line ball portion, its other end is connected with the tilting section that is inclined upwardly and arranges towards line ball portion direction, described tilting section is away from supporting and be provided with supporting section between one end of horizontal segment and horizontal segment, described supporting section comprises vertical portion, one end of described vertical portion is connected with tilting section, its other end extends the flexible feet of bifurcated to horizontal segment direction, the side projection view of described supporting section is " people " font.
By adopting technique scheme, " people " font supporting section forming with vertical portion and flexible feet replaces original tilted section, when the upper end of contact pin extruding tilting section, supporting section is stressed to be pressed down, the flexible feet deformation that bifurcated arranges, for the upper end of tilting section provides elasticity holding power, by contact pin butt securely, according to the length of the proportional control flexible feet of the shared supporting section in vertical portion, set out best proportion, can control by vertical portion the largest deformation amount of contact site, can control elastic strength according to the length of flexible feet again, elastic force is disperseed by flexible feet, compare leg-of-mutton reed structure, structural strength is stronger, fatigue life is longer.
The utility model is further set to: described flexible feet is set to two.
By adopting technique scheme, two flexible feets, can pass through cutting sheet material, then to both sides, be bent to form respectively, easy to process, cost-saving.
The utility model is further set to: the Length Ratio of described vertical portion and flexible feet is 1:1.
By adopting technique scheme, in repeatedly endurance is tested, the length that vertical portion equals flexible feet is optimal proportion, and elastic force and fatigue resistance integration capability are best.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model terminal embodiment.
Description of reference numerals: 1, contact site; 11, horizontal segment; 12, tilting section; 13, supporting section; 131, vertical portion; 132, flexible feet; 2, line ball portion.
Embodiment
With reference to Fig. 1, the utility model terminal embodiment is described further.
A kind of terminal comprises contact site 1 and line ball portion 2, described contact site 1 comprises horizontal segment 11, one end of described horizontal segment 11 is connected with line ball portion 2, its other end is connected with the tilting section 12 that is inclined upwardly and arranges towards line ball portion 2 directions, described tilting section 12 is away from supporting and be provided with supporting section 13 between one end of horizontal segment 11 and horizontal segment 11, described supporting section 13 comprises vertical portion 131, one end of described vertical portion 131 is connected with tilting section 12, its other end extends the flexible feet 132 of bifurcated to horizontal segment 11 directions, the side projection view of described supporting section 13 is " people " font.
By adopting technique scheme, " people " font supporting section 13 forming with vertical portion 131 and flexible feet 132 replaces original tilted section 12, when the upper end of contact pin extruding tilting section 12, supporting section 13 is stressed to be pressed down, flexible feet 132 deformation that bifurcated arranges, for the upper end of tilting section 12 provides elasticity holding power, by contact pin butt securely, according to the length of the proportional control flexible feet 132 of the shared supporting section 13 in vertical portion 131, set out best proportion, can control by vertical portion 131 the largest deformation amount of contact site 1, can control elastic strength according to the length of flexible feet 132 again, elastic force is disperseed by flexible feet 132, compare leg-of-mutton reed structure, structural strength is stronger, fatigue life is longer.
Described flexible feet 132 is set to two.
By adopting technique scheme, two flexible feets 132, can pass through cutting sheet material, then to both sides, be bent to form respectively, easy to process, cost-saving.
The Length Ratio of described vertical portion 131 and flexible feet 132 is 1:1.
By adopting technique scheme, in repeatedly endurance is tested, the length that vertical portion 131 equals flexible feet 132 is optimal proportion, and elastic force and fatigue resistance integration capability are best.
