Description

Connector terminals

[technical field]

The utility model relates to a kind of connector terminals.

[background technology]

Connector connects electronic component by terminal and/or motherboard intercropping combination is quite general technology with being electrically connected, after making connector terminals insert in the motherboard jack, has good contact, more common at present connector terminals structure promptly as shown in Figure 5, it is that shaft-like terminal body (70) with metallic plugs in the perforation (82) that is fixed on electronic component (80) (or connector), insertion end (72) then is exposed to the outside, on this insertion end (72), be provided with outer the portion (74) that supports to both sides, cooperate Fig. 6 to see it, be formed with a mesopore (740) on this insertion end (72), form outer the portion (74) of a curved arc shape respectively in this mesopore (740) both sides, when in the jack that the insertion end (72) of this terminal body (70) is inserted motherboard or corresponding electronic element, promptly as shown in Figure 7, this two outer lateral surface of opening portions (74) can abut within the jack (90) on the wall, uses the effect that conducts that provides appropriate.

Terminal body (70) as shown in Fig. 5～7 finds that under study for action it does not reach the degree of perfection as yet though structure can reach basic functional demand when utilization, and it still exists following disappearance to remain to be improved:

1. its contact area deficiency, see it with general existing motherboard, the aperture of its jack (90) has from 0.9～1.2mm, though the attempt of existing terminal body (70) is suitable for the jack (90) in various different apertures by its outer design of opening portion (74), but in the time of in fact in the jack (90) that inserts different apertures, its outer contact area of opening between portion (74) and jack (90) is all inequality, though existing terminal body (70) is made into circular arc with side outside its outer portion (74), but when the jack (90) in the different apertures of collocation, contact area therebetween is still very limited, and the conducting effect is good inadequately.

2. be easy to produce tired, because when a portion (74) is in inserting jack (90) outward, system utilizes the elasticity of its material own that the outer power that supports of opening is provided, but owing to fail to provide the outer appropriate bracing force of portion (74) of opening on its structural design, so support strength using its outer portion (74) of a period of time Hou promptly can lose because of metal fatigue.

3. structural strength is not enough and easily deformable, when a portion (74) is in inserting jack (90) outside the existing terminal body (70), Yi Yin is oppressed and is out of shape, when if user's desire plugs it replacing in the jack (90) of larger aperture, tend to because open the distortion of portion (74) and form poor flow outward.

[utility model content]

Because existing connector terminals body is opened the most ideal of the structural design of portion's part outside, the purpose of this utility model is to provide a kind of connector terminals, when this terminal inserts in the jack, can increase contact-making surface with the jack internal face, improve this terminal elasticity and strengthen its structure.

The technical solution of the utility model is:

A kind of connector terminals comprises a body, and this body has an insertion end, it is characterized in that: open portion outside these insertion end both sides are provided with, and are folded with middle protuberance between these two outer portions, protuberance and two outer opening between portion are formed with the face of tearing in this.

By this, can two outer open that protuberance provide suitable distortion elasticity in portions and, when this terminal inserts in jack, can allow the outer surface jack internal face that reclines respectively of opening outside portion and the middle protuberance, to reach the effect of increase contact-making surface and reinforced structure by this.

Connector terminals of the present utility model can also have following additional technical characterictic:

Should can protrude by a side of insertion end by middle protuberance.

Should in protuberance outer open that the formed face of tearing slightly is parallel mutually between portions with two.

Should be arc surface by the outer outer surface of opening portion and middle protuberance.

When connector terminals of the present utility model is inserted in jack in this insertion end, can allow and open outside portion and the middle protuberance surface jack internal face that reclines respectively outward, and can reach effects such as increasing contact-making surface, lifting elastic space and reinforced structure.

In order further to understand the architectural feature of aforementioned purpose and the utility model, attached now with graphic detailed description as the back:

[embodiment]

See also shown in Figure 1, connector terminals of the present utility model (10) basic structure is identical with existing terminal, comprise a body, this body has an insertion end (12), but insertion end (12) be provided with outside the both sides open portion (14) and be folded in outer open between the portion (14) among protuberance (16).

Cooperate Fig. 2,3,4 see it than Cui embodiment schematic diagram, protuberance in this (16,16 ', 16 ＂) be to tear formation by the two outer materials of opening between portions (14,14 ', 14 ＂), that is in middle protuberance (16,16 ', 16 ＂) and the two outer portions (14 of opening, 14 ', 14 ＂) between be formed with the face of tearing that slightly is parallel (18,18 ', 18 ＂), simultaneously should in protuberance (16,16 ', 16 ＂) protrude by a side of insertion end (12,12 ', 12 ＂), by this structural arrangements, when insertion end (12,12 ', 12 ＂) is inserted in the jack (20), middle protuberance (16,16 ', 16 ＂) can be because being subjected within the jack (20) the footpath compressing retraction two outer open portions (14,14 ', 14 ＂) between, again two outer open portion (14,14 ', 14 ＂) also can be because footpath compressing within the jack (20) to being provided with middle protuberance (16,16 ', 16 ＂) in addition side produces deflection, and can form suitable distortion, with the elastic space that improves the utility model applicable to the jack (20) of pore size difference.

In addition by shown in Fig. 2,3,4 as can be known, the terminal insertion end of the utility model (12,12 ', a portion 12 ＂) (14,14 ', 14 ＂) and middle protuberance (16,16 ', 16 ＂) outside the surface all form arc surface, by this in this insertion end (12,12 ', 12 ＂) when inserting in the jack (20), can allow (14,14 ', 14 ＂) and middle protuberance (16,16 ', 16 ＂) surface jack (20) internal face that reclines respectively outside, and can reach the effect that increases contact-making surface.

The utility model is with (14,14 ', 14 ＂) and middle protuberance (16,16 ', 16 ＂) structural arrangements, in insertion end (12,12 ', when 12 ＂) inserting in the jack (20), the mode of texturing that a portion (74) makes mesopore (740) dwindle to central authorities' compressing outside its mode of texturing and known two is completely different, according to the structural arrangements of the utility model, can promote insertion end (12,12 ', 12 ＂) structural strength, and reach the effect that lowers elastic fatigue.
