Embodiment
The utility model embodiment provides a kind of row's pin type connector, can solve row's pin type connector of the prior art, can't adopt surface mount process, thereby cause the technical problem that operating process is loaded down with trivial details, production efficiency is low.
The utility model embodiment provides a kind of row's pin type connector, shown in Fig. 1 (a), Fig. 1 (b), Fig. 1 (c), Fig. 1 (d) and Fig. 1 (e), comprise: the policy base 3 that is provided with a plurality of pin holes 31, and insert a plurality of policies 2 in each pin holes 31 respectively, also comprise: top cover 1, be positioned at the top of described policy base 3 and described policy 2, and with described policy base 3 between fixedly connected.
Wherein, extend the first side wall 11 under first side direction of top cover 1, extend second sidewall 16 under second side direction of described top cover 1, wherein, first side of described top cover 1 is relative with second side, and the spacing between the described the first side wall 11 and second sidewall 16 is not more than the length of described policy base 3, and the then described the first side wall 11 and second sidewall 16 are fixed in the both sides of described policy base 3.And, tightr for what engage between the side 32 that makes the first side wall 11 and second sidewall 16 and policy base 3, spacing between the first side wall 11 and second sidewall 16 can be designed to such an extent that be slightly less than the length of policy base 3, for example, spacing between the first side wall 11 and second sidewall 16 can be designed to the little 0.2mm of length than policy base 3, certainly, also can take other numerical value, thereby realize that by interference fit tight between top cover 1 and the policy base 3 engages, thus assurance during by the sucking-off of SMT chip mounter suction nozzle the top cover 1 of this row's pin type connector can not separate with policy base 3.Perhaps, in order to make engage between top cover 1 and the policy base 3 tightr, the first side wall 11 and second sidewall 16 can also be designed to not is fully perpendicular to the plane, end face 15 place of top cover 1, but make the angle between the first side wall 11 and second sidewall 16 and the end face 15 be slightly less than 90 degree, that is: the first side wall 11 and second sidewall 16 are tilted to the inside, thereby make and engage closelyr between top cover 1 and the policy base 3.When specific implementation, can also adopt other modes to realize fixing between top cover 1 and the policy base 3, for example, can also a buckle etc. be set in the bottom of the first side wall 11 and second sidewall 16, in a word, as long as can realize secure fixation between top cover 1 and the policy base 3.Because above policy base 3 and policy 2, be provided with a top cover, the top surface area of this top cover is big and end face is very smooth, thereby can the row's of making pin type connector can be by the suction nozzle sucking-off braid over braid of SMT machine, and steadily, accurately in the pin holes of insert module pcb board, because utilized surface mount process, so avoided manually-operated loaded down with trivial details, improved production efficiency.Here, top cover can adopt plastic cement material to make.
In traditional row's pin type connector, because policy 2 is made up of first end 21 and the second end 22, wherein, after first end 21 inserts policy base 3, the second end 22 is exposed at the outside of policy base 3 and extends to a side, thereby when causing arranging the pin type connector and need be welded near the power module edge, because the self gravitation effect, the lateral deviation that this row's pin type connector can stretch out to the second end 22 of policy 2 is oblique.This deflection can cause the failure welding of through hole Reflow Soldering, influences functions of modules, and then has influence on the functional stabilization of system.Therefore, also be provided with at least one supporting bracket 17 in the bottom of top cover 1 in the utility model, the bottom surface of the bottom surface of described supporting bracket 17 and described policy base 3 is positioned at same horizontal plane, then when using this row's pin type connector, can effectively prevent deflection.And, on the bottom surface of described supporting bracket 17, also extend at least one first pad pin 13, the bottom surface of the then described first pad pin 13 and the bottom surface of described policy base 3 are positioned at same horizontal plane, and wherein, the first pad pin 13 is positioned at the second end 22 outward extending sides of described policy 2.And, on the bottom surface of described policy base 3, several can also be set, for example six second are filled up pin 33, and the bottom surface of the bottom surface of then described supporting bracket 17 and the described second pad pin 33 is positioned at same horizontal plane and gets final product.
And, in order to make the position relation between top cover 1 and the policy base 3 more stable, also be provided with height and the consistent square spacing breach of width with policy base 3 in supporting bracket 17 1 sides, then described supporting bracket contacts with described policy base by described square spacing breach.Concrete, after this top cover 1 fixes with policy base 3, first side 12 and the end face 35 of policy base 3 of this square spacing breach are fitted mutually, fit mutually in second side 14 and the side 34 of policy base 3 of this square spacing breach, like this, second side 14 of this square spacing breach and first side 12 have just guaranteed top cover and policy base all at correct rigging position, thereby define the position relation between top cover 1 and the policy base 3, make the two secure fixation.
The quantity of supporting bracket 17 can be adjusted as required among the utility model embodiment, has adopted two supporting brackets in Fig. 1 (a), certainly, also can increase or reduce the quantity of supporting bracket as required.
In Fig. 2, the first end 21 of policy is inserted in the pin holes of power module pcb board 4 correspondences, through the Reflow Soldering welding, thereby realizes fixing between this row's pin type connector and the power module pcb board 4.
In Fig. 3, after this row's pin type connector was welded on the power module pcb board 4, top cover 1 can be reclaimed by manual removal, realized recycling.The second end 22 of policy is soldered to as signal output part in the pin holes of system single board 5 correspondences, through wave-soldering welding, thereby utilizes this row's pin type connector to realize communicating by letter between power module and the system single board.
In the utility model embodiment, anti-inserted during for modules such as the row's of preventing pin type connector insertion power supplys, in can a plurality of pin holes with policy base 3, the spacing between the spacing between two pin holes in left side and two pin holes on the right side be designed to unequal.Like this, just can prevent effectively that module is anti-inserted, thereby improve rate of finished products greatly, reduce the possibility of misoperation.
Among the utility model embodiment, the row's of employing pin type connector has realized that power module is connected with the structure of system single board and the signal transmission.This row's pin type connector can adopt the SMT paster technique to install, and is welded on the power module by surface mount process and the Reflow Soldering of through hole attachment process process combined process through hole.Also have counnter attack simultaneously and insert, prevent functions such as crooked.Shorten weld time greatly, improved production efficiency by the row's pin type connector that adopts the utility model embodiment to provide, reduced workman's error rate, and then improved welding quality, also improved the power module first-pass yield, strengthened power module stability.
Obviously, those skilled in the art can carry out various changes and modification to the utility model and not break away from spirit and scope of the present utility model.Like this, if of the present utility model these are revised and modification belongs within the scope of the utility model claim and equivalent technologies thereof, then the utility model also is intended to comprise these changes and modification interior.
