Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail, but not as to restriction of the present utility model.
Fig. 1 is according to the installation diagram of the circuit board assemblies that comprises board to board connector of the utility model embodiment.As shown in Figure 1, the circuit board assemblies of the utility model embodiment comprises opposed first circuit board 1 and second circuit board 2 and the board to board connector between first circuit board 1 and second circuit board 2.
Fig. 2 is according to the sectional axonometric drawing of the circuit board assemblies that comprises board to board connector of the utility model embodiment.Fig. 3 is according to the local amplification profile of the circuit board assemblies that comprises board to board connector of the utility model embodiment.As shown in Figures 2 and 3, the board to board connector of the utility model embodiment, between opposed first circuit board 1 and second circuit board 2, comprise stacked upper circuit board plate material body 3 and lower insulation plate body 4, upper circuit board plate material body (pcb board material body) 3 is provided with at least one via hole 31, in each via hole 31, insert the upper elastic arm terminal 5 that can contact with via hole 31 close contacts and with first circuit board 1 conducting, on lower insulation plate body 4, there is the slotted eye 41 with at least one via hole 31 relevant positions, the lower elastic arm terminal 6 that can contact with second circuit board 2 conductings is installed in each slotted eye 41, upper elastic arm terminal 5 contacts with lower elastic arm terminal 6 conductings.When mounted, can will elastic arm terminal 5 from top and insert in via hole 31, will elastic arm terminal 6 to pack in slotted eye 41 from below.The size of slotted eye 41 arranges as required, can hold as long as ensure the part (if any) that lower elastic arm terminal 6 and upper elastic arm terminal 5 lower ends exceed via hole 31.Like this, being connected of via hole 31 conductings by upper and lower elastic arm terminal 5,6 and upper circuit board plate material body 3, electrical connection and the mechanical connection of the high reliability between circuit board are realized, promote the reliability of whole circuit board assemblies, and this structure makes the assembling of board to board connector very easy, the assembling of circuit board assemblies is also very easy thus.
Wherein, upper elastic arm terminal 5 can Elastic Sliding contact with lower elastic arm terminal 6.Can strengthen like this adaptability of whole circuit board assemblies, increase tolerance.
For example, as shown in Figures 2 and 3, upper elastic arm terminal 5 can roughly be inversion U-shaped, and lower elastic arm terminal 6 can roughly take the shape of the letter U, and two free ends of two free ends of lower elastic arm terminal 6 and upper flexible terminal can be stacked with.Can realize the contact of upper and lower elastic arm terminal, especially Elastic Sliding contact with simple structure like this.Certainly, it will also be appreciated that other structures of upper and lower elastic arm terminal, as long as can realize the contact (especially sliding contact) of the two.
For example, as shown in Figures 2 and 3, two free ends of upper flexible terminal can be in the outside of two of lower elastic arm terminal 6 free end.Certainly, two of upper flexible terminal free ends also can be in the inner side of two of lower elastic arm terminal 6 free end.Can ensure like this sliding contact performance that upper and lower elastic arm terminal is good.
For example, as shown in Figure 3, two free ends of upper elastic arm terminal 5 can have end kink 51, and two free ends of lower elastic arm terminal 6 can have corresponding end kink 61.Like this, upper elastic arm terminal 5 can contact in end kink 51,61 positions with lower elastic arm terminal 6, on the one hand, the active force of these 4 positions will make elastic arm terminal 5 expand towards the left and right sides, this mode can ensure that elastic arm terminal 5 left and right sides elastic arms reliably contact with via hole 31, on the other hand, this set is more conducive to realize the sliding contact of upper and lower elastic arm terminal, thereby can realize electrical connection and mechanical connection more reliably between circuit board.
For example, as shown in Figure 3, the middle part of upper elastic arm terminal 5 can be provided with middle kink 52.Can ensure that like this elastic arm terminal 5 left and right sides elastic arms reliably contact at middle kink 52 places with via hole 31.This mode can ensure that elastic arm terminal 5 left and right sides elastic arms reliably contact with via hole 31, thereby realizes electrical connection and mechanical connection more reliably between circuit board.
For example, two free ends of lower elastic arm terminal 6 can stretch into via hole 31, and certainly, two free ends of upper elastic arm terminal 5 also can stretch into slotted eye 41.Be convenient to like this realize the sliding contact performance that upper and lower elastic arm terminal is good, be also conducive to the location of the two.
For example, as shown in Figure 3, in slotted eye 41, can there is the maintenance piece 42 for fixing lower elastic arm terminal 6.So more be conducive to the fixing of lower elastic arm terminal 6.As Fig. 1 and Fig. 3 best image, the lower end of maintenance piece 42 can exceed the plate body basal plane of lower insulation plate body 4.Like this, can guarantee that lower elastic arm terminal 6 contacts with the conducting of second circuit board 2.
Certainly, be more than preferred implementation of the present utility model.It should be pointed out that for those skilled in the art, not departing under the prerequisite of the utility model general principle, can also make some improvements and modifications, these improvements and modifications are also considered as protection range of the present utility model.
