Abstract
The utility model relates to a positioning structure with a plug-in module on a PCB (printed circuit board). According to the utility model, hollow holes with shapes adaptive to shapes of the lower ends of female headers of an SMT (subminia-ture Tube) are formed in the PCB, the lower ends of the female headers of the SMT are inserted into the hollow holes, and wiring terminals at the lower ends of the female headers of the SMT are bent outwards on the back of the PCB and are welded on the back of the PCB. With the adoption of the structure, the height of the female headers of the whole SMT is balanced out by the height of the PCB; and the female headers of the SMT only can be arranged to be stretch out of the hollow holes of the PCB, and therefore the problem that the module can not be installed due to deviation in welding of the female headers of the SMT is effectively solved.
Description
Technical field
The utility model belongs to electronic technology field, relates to a kind of location of electron trade universal PC B strip card module, the location structure of band card module on especially a kind of pcb board.
Background technology
In the existing technical scheme, the module that major part all will have the band plug-in unit now directly is welded on the base plate, or row of welding is female on base plate, directly plugs, and is as shown in Figure 1.There is following defective in this locate mode:
(1) highly bad control can only be decided by mother's row self height.
(2) mode of traditional direct welding brings very big trouble for dismounting, maintenance
(3) if the female location of the row of SMT is inaccurate, the welding position is inaccurate makes troubles to installation again.
The utility model content
The purpose of the utility model is to overcome the shortcoming of above-mentioned prior art, and a kind of location structure with card module is provided, and this location structure is through the mode of reverse welding, reasonable in design, can make dismounting, keep in repair very convenient.
The purpose of the utility model solves through following technical scheme:
The location structure of band card module on this pcb board; On pcb board, offer the hollow hole that adapts with the female lower end of the row of SMT shape; The row of said SMT inserts in the hollow hole female lower end, and the female lower end binding post of the row of SMT outwards bends and is welded on the pcb board back side at the pcb board back side.
On mother row of above-mentioned SMT, peg graft and be with card module.
The utlity model has following beneficial effect:
The location structure of the utility model makes the female height of row of whole SMT offset a part by the height of pcb board; And; The row of SMT can only stretch out at the pcb board openwork hole female position, thus the problem that the module of effectively having avoided the female weldering of the row local derviation of SMT to cause can't be installed.
Description of drawings
Fig. 1 is prior art constructions figure;
Fig. 2 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
Referring to Fig. 2; The location structure of band card module on the pcb board of the utility model; Be on pcb board 1, to offer the hollow hole 3 that adapts with the female 2 lower end shapes of the row of SMT; Insert in the hollow hole 3 row of SMT female 2 lower end, and the row of SMT female 2 lower end binding post outwards bends and is welded on the pcb board back side at the pcb board back side.On the row female 2 of said SMT, peg graft and be with card module.
In sum; The utility model makes the female height of row of whole SMT offset a part by the height of pcb board; And the row of SMT can only stretch out at the pcb board openwork hole female position, thus the problem that the module of effectively having avoided the female weldering of the row local derviation of SMT to cause can't be installed.
Claims (2)
1. the location structure of band card module on the pcb board; It is characterized in that; On pcb board (1), offer the hollow hole (3) that adapts with female (2) lower end of the row of SMT shape; Insert in the hollow hole (3) row's of said SMT female (2) lower end, and the row's of SMT female (2) lower end binding post outwards bends and is welded on the pcb board back side at the pcb board back side.
2. the location structure of band card module is characterized in that on the pcb board according to claim 1, goes up the band card module of pegging graft the row of said SMT female (2).
