Abstract
The utility model relates to an electric connector terminal, which is positioned in the insulation body of the electric connector and used for eclectically connecting the electron card and the printing circuit board. The terminal of the electric connector is basically in an U shape, which mainly comprises a fixed holding part in a rectangle plate shape clamped in the containing groove channel of the insulation body, a contact part protruded from the containing groove channel of the insulation body, and a connecting par for connecting the fixed holding part and the contact part. The free terminal end of the fixed holding party is bended downwards and extended to form the welding part. Wherein, the side edge for the fixed holding part near to the connection part is convergent towards inside and in a smooth arc-shaped installation.
Description
[technical field]
The utility model refers to a kind of electric connector terminal that is used for electronic cards is electrically connected to printed circuit board (PCB) especially about a kind of electric connector terminal.
[background technology]
Electric connector, particularly electronic card coupler is the connector that a kind of subcard of powering is planted, and this electric connector generally is used for mobile phone, the embedded electric connector terminal of holding of electric connector can be electrically connected to electronic cards on the printed circuit board (PCB) of mobile phone inside as conducting medium.
A kind of existing electric connector terminal roughly is U type structure, and it mainly comprises: the rectangular flat holding parts in surface; Be the acute angle setting with holding parts, and be the contact site of smooth curved arch; Elasticity connects the carrier of holding parts and contact site.Wherein, the free terminal of holding parts extends a weld part.
One group of electric connector terminal is assembled in constitutes electric connector in the insulating body, wherein, described insulating body is provided with the conduit of accommodating in order to the fixed conductive terminals holding parts; The part that contact site is arch protrudes in insulating body and the connecting portion by bending is connected with holding parts; Weld part extends insulating body downwards by the free terminal of holding parts, welds mutually with printed circuit board (PCB).When electronic cards is installed in the electric connector, electric connector terminal is under the effect of the downward pressure that electronic cards applies, contact site generation strain, and cause at the knee of electric connector terminal carrier stress and concentrate, stress is concentrated and is easily made the knee of carrier reach fatigue limit, make carrier generation plastic deformation, even may cause the electric connector terminal fracture, have influence on electrically conducting of electric connector.
Therefore, necessary this electric connector terminal structure is improved to address the aforementioned drawbacks.
[utility model content]
The purpose of this utility model is to provide a kind of electric connector terminal that can guarantee serviceability and life-span.
Be to realize foregoing, the utility model adopts following technical scheme: a kind of electric connector terminal, be used for electrically connecting the electric connector of electronic cards and printed circuit board (PCB), and roughly be U type structure, it mainly comprises: the rectangular flat holding parts in surface; Be the acute angle setting with holding parts, and be the contact site of smooth curved arch; The carrier that connects holding parts and contact site; The free terminal of holding parts bends extension downwards, forms weld part.Wherein, holding parts is near the lateral edges toe-in of carrier one end and be level and smooth circular-arc setting.
With respect to prior art, the utility model electric connector terminal has following beneficial effect: holding parts is near the lateral edges toe-in of carrier one end and be level and smooth circular-arc setting, when contact site is pressed, the stress at carrier place is to the diffusion of the level and smooth arc position place of holding parts convergence, the phenomenon of avoiding stress to concentrate takes place, thus the serviceability and the life-span of improving electric connector terminal.
[description of drawings]
Fig. 1 is the stereogram of the utility model electric connector terminal.
Fig. 2 is the end view of electric connector terminal shown in Figure 1.
Fig. 3 is the upward view of electric connector terminal shown in Figure 1.
[embodiment]
See also Fig. 1 to shown in Figure 3, electric connector terminal 100 is used for electrically connecting the electric connector (not shown) of electronic cards (not shown) and printed circuit board (PCB) (not shown), roughly be U type structure, it mainly comprises: holding parts 10, carrier 20, contact site 30, weld part 40 and interference part 60.
Holding parts 10 rectangular tabulars, its free terminal bending downwards extends to form weld part 40, and convex with bur district 50 near the lateral edges of weld part 40 1 ends to both sides, holding parts 10 link to each other with carrier 20 end the lateral edges toe-in and be level and smooth circular-arc setting.
Contact site 30 is the acute angle setting with holding parts 10 and links to each other by a slick and sly crooked carrier 20, and described contact site 30 is the arch setting away from an end of carrier 20.The free terminal of contact site 30 forms interference part 60 to the both sides horizontal-extending.
One group of electric connector terminal 100 is assembled in composition electric connector in the insulating body (not shown), and described insulating body is provided with accommodates conduit (not shown).Wherein, holding parts 10 is fastened in accommodating in the conduit of insulating body, and the bur district 50 of holding parts 10 both sides presses on the sidewall of accommodating conduit, makes holding parts 10 and accommodate the stable interference of conduit to hold.Weld part 40 protrudes from insulating body downwards and is welded in printed circuit board (PCB), and it is protruding upward in insulating body that contact site 30 is the part of arch, so that reach excellent electrical property and contact with the electronic cards in being loaded on electric connector.Simultaneously, interference part 60 is also interfered to be fastened in and is accommodated in the conduit, plays the effect of stable electrical bonder terminal 100 jointly with holding parts 10.
During use, when electronic cards is installed in the electric connector, the contact site 30 of electric connector terminal 100 is subjected to electronic cards and applies downward pressure generation strain, because holding parts 10 is near the lateral edges toe-in of carrier 20 1 ends and be level and smooth circular-arc setting, when contact site 30 is pressed, the stress at carrier 20 places is to the level and smooth arc position place diffusion of holding parts 10 convergences, and the phenomenon of avoiding stress to concentrate takes place, thus the serviceability and the life-span of improving electric connector terminal 100.
Above-mentioned only is the utility model one preferred implementation, is protection range of the present utility model based on any improvement of making under the utility model design prerequisite.
