Come embodiment of the present invention at length is described below with reference to accompanying drawing, so that show advantage of the present invention.
Extremely shown in Figure 3 like Fig. 1; Embodiment of the invention Board-to-Board Electrical Connector socket and plug; Said socket comprises jack body 100, and it is made up of insulating material, also comprises some female terminals 1; Said female terminal 1 is placed in the jack body 100 through socket end pilot trench 101, and said socket also has receiving space 102 and is used to accommodate plug; Said plug comprises the header body 200 that also is made up of insulating material; Also comprise plug terminal 2; Said plug terminal 2 is placed in the header body 200 through plug end pilot trench 201, and said plug terminal 2 can be electrically connected with female terminal in plug insertion socket the time.Said socket is electrically connected with a circuit board through first weld part on the female terminal 1; Said plug is electrically connected with another circuit board through second weld part on the plug terminal 2; Directly be electrically connected through plug terminal behind the plug insertion socket 2 and female terminal 1, thereby realized the electrical connection between two circuit boards.Describe in detail in the face of plug terminal 2 and female terminal 1 down.
As shown in Figure 4; The female terminal 1 of the embodiment of the invention comprises base portion 10; Said base portion 10 extends upward out holding parts 15, and base portion 10 1 ends extend first weld part 11, and the other end extends first elastic arm 12; First elastic arm 12 extends upward out first contact site 14; Said holding parts 15 extends second elastic arm 13 and links to each other with first contact site 14, and said first elastic arm 12, second elastic arm 13, first contact site 14 and holding parts 15 form elastic spaces 17, and said elastic space 17 makes the win contact site 14 and second elastic arm 13 and first elastic arm 12 elastically-deformable the time, have the deformation space.Simultaneously according to the resistance calculations formula: R=p*l/s (p-resistivity; L-resistance length; S-with the resistance area of section of current vertical), learn that by formula resistivity and sectional area are inversely proportional to; Compared with prior art; In the structure of the embodiment of the invention, electric current flows along first elastic arm and the second elastic arm both direction respectively simultaneously, under the certain situation of material thickness and overall dimension; The average cross-section of two elastic arm structures is long-pending to reach maximum, thereby obtains a less impedance.This meets the more little favourable more aspect of general connector requirement contact impedance.
Shown in Fig. 4 to 7, the plug terminal 2 that matches with embodiment of the invention female terminal can adopt like the list structure in 4, also can be the laminated structure like Fig. 5 to Fig. 7, and they all have second weld part 21 and second contact site 24.Said female terminal 1 is realized being electrically connected through the buckle structure that is arranged on first contact site 14 and/or second contact site 24 with plug terminal 2.Said buckle structure make the contact site 14 of winning produce elastic deformations and with second contact site, 24 snap-fit, among the present invention between vertical socket terminal 1 and the plug terminal 2 power of contact-making surface be called as positive force.Positive force is the key parameter of assessment contact reliability, can be like the arm structure of the embodiment of the invention so that this positive force is bigger compared to prior art, thus make the bonder terminal contact more firm.With the height of 0.95mm, the female terminal of 0.12 material thickness is an example, and the positive force of monolateral elastic arm is 50g-100g, and two elastic arm positive force can reach more than the 150g, and its positive force has obtained significant raising.
More firm in order to make that two-terminal combines; Preferred said buckle structure comprises the convexity 14 ' that is arranged on first contact site 14, preferred said buckle structure also comprise be arranged on second contact site 24 can with the arcwall face 24 ' of said protruding 14 ' contact matching.
Embodiment one: said buckle structure as shown in Figure 6 comprises the convexity 14 ' that is arranged on first contact site 14; Also comprise be arranged on second contact site 24 can with the arcwall face 24 ' of said protruding 14 ' contact matching; In the process of plug insertion socket; Since have protruding 14 ' with the structure of arcwall face 24 ', plug terminal 1 receives one earlier more energetically, first elastic arm 12 and second elastic arm 13 and the bigger deformation of first contact site, 14 generations one; When protruding 14 ' cooperated with arcwall face 24 ' fully, said deformation diminished and makes plug terminal 2 and female terminal 1 stably snap together.
A kind of in addition improved procedure is that said buckle structure comprises the convexity 24 that is arranged on second contact site 24 ", preferred said buckle structure also comprise be arranged on first contact site can with said second contact site 24 protruding 24 " arcwall face 14 of contact matching ".
Embodiment two: as shown in Figure 7; Said buckle structure comprises the convexity 24 that is arranged on second contact site 24 "; also comprise be arranged on first contact site can with said second contact site 24 protruding 24 " arcwall face 14 of contact matching ", its principle similar embodiment one is said to repeat no more at this.
As shown in Figs. 4-6, preferred said holding parts 15 also has fixed part 16, said fixed part 16 can with socket end pilot trench 101 interference engagement.Even if the purpose that is provided with like this is to make second contact site 24, first contact site 14 of extrusion friction female terminal 1 repeatedly of plug terminal 2 for plug in the process of plug plug plugs repeatedly; Female terminal 1 can be not that the axle center produces deflection or displacement with holding parts 15 also; Make Board-to-Board Electrical Connector among the present invention than existing Board-to-Board Electrical Connector; Female terminal 1 is more firm, and then has improved the stability of plug terminal 2 and 1 electric connection of female terminal.Said fixed part 16 can be that lacerated perk also can be the circle bag of protrusion or the convexity of other shapes, as long as can adopt with the structure of female terminal cell wall interference engagement.
More than be merely embodiment of the present invention and embodiment, be not used for limiting protection scope of the present invention, the every modification and equivalent variations thereof of under the present invention conceives, being carried out of belonging to all should be regarded as within protection scope of the present invention.
