Abstract
The utility model discloses a SMT pad structure of being torn off when preventing plug, this structure includes the PCB board and sets up the pad on the PCB board that be equipped with the via hole including actual network pin pad and NC pin pad, NC pin pad department. The utility model discloses add the via hole on the pad of arranging the NC pin position of female (or arrange and insert) corresponding to SMT, strengthen the adhesive force of connector pad for be difficult to tear off the pad during plug. The utility model discloses it is very convenient to realize, can solve the problem of being torn off when SMT arranges female (or arrange and insert) plug by to a great extent.
Description
Technical field
The utility model discloses a kind of pad structure, particularly a kind of when preventing plug by the SMT pad structure torn off, it is mainly used in the PCB product of the female or socket structure of SMT row.
Background technology
Mother row or socket are electric connector structures conventional in prior art, and be widely used in the connection of various signal, data cube computation and power supply connection, the common structure of mother row or socket has contact pin type structure and Surface Mount (i.e. SMT) formula structure usually.Because the pin arranging mother or socket is numerous, wherein there are some pins in electrical connection, play real effect, some pin does not play any effect, be unsettled design, be referred to as NC pin, SMT row female (or socket) is generally left intact to its NC pin in existing PCB design, the unsettled setting of pad by its correspondence, be connected with it owing to there is no cabling, cause its adhesive force very little, so just easily cause row's female (or socket) each pin unbalance stress when plugging, the pad be easy to corresponding for NC pin in swapping process is torn off, even tear off whole connector, PCB is caused to damage.
Summary of the invention
For above-mentioned SMT row female (or socket) the of the prior art each pin unbalance stress when plugging mentioned, hold flimsy shortcoming, the utility model provide a kind of newly prevent plug time by the SMT pad structure torn off, it increases via hole on the pad corresponding to NC pin, certain fixation is served to NC pin, make connector uniform force, not easily torn off during plug.
The utility model solve its technical problem adopt technical scheme be: a kind of prevent plug time by the SMT pad structure torn off, this structure comprises pcb board and is arranged on the pad on pcb board, pad includes real network pin pad and NC pin pad, and NC pin pad place is provided with via hole.
The technical scheme that the utility model solves the employing of its technical problem further comprises:
Described pcb board is double sided board or multi-layer sheet.
The upper via hole position that corresponds to of described pcb board every layer is equipped with an auxiliary pad.
Described each NC pin pad place is provided with one or two via hole.
The beneficial effects of the utility model are: the utility model sets up via hole on the pad of NC Pin locations corresponding to SMT row female (or socket), strengthens the adhesive force of connector pad, make to be not easy to tear off pad during plug.The utility model implements very convenient, can solve to a great extent when SMT row female (or socket) plugs by the problem torn off.
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model part section structural representation.
In figure, 1-PCB plate, 2-electric connector, 3-real network pin pad, 4-NC pin pad, 5-circuit, 6-via hole, 7-assists pad.
Embodiment
The present embodiment is the utility model preferred implementation, and other its principles all are identical with the present embodiment or approximate with basic structure, all within the utility model protection range.
Please refer to accompanying drawing 1 and accompanying drawing 2, the pad that the utility model mainly includes pcb board 1 and is arranged on pcb board 1, in the present embodiment, pcb board 1 can be double sided board or multi-layer sheet, the pad related in the utility model mainly corresponds to the pad of electric connector 2 pin, pad includes real network pin pad 3 and NC pin pad 4, electric connector 2 in the present embodiment can be SMT mother row or socket, in practical application, may owing to being subject to certain restriction, some pin of electric connector 2 is defined as NC pin, some pin is defined as real network pin, pad pcb board 1 corresponding to NC pin is defined as NC pin pad 4, pad corresponding to real network pin is defined as real network pin pad 3, real network pin pad 3 is electrically connected with other components and parts on pcb board 1 by circuit 5, the unsettled setting of NC pin pad 4.In the utility model, at NC pin pad 4, place is provided with via hole 6, can establish a via hole, also can establish multiple via hole corresponding to each NC pin pad 4, first-selected for being provided with one or two via hole.In the present embodiment, circuit board adopts double sided board or multi-layer sheet, every layer circuit board corresponds to via hole 6 position and is equipped with an auxiliary pad 7, for increasing the adhesive force of via hole 6.Like this, pad will be fixed on pcb board 1 by via hole 6, and make NC pin pad 4 add adhesive force on pcb board 1, when making plug-in connector, pad can not be torn off.
The utility model sets up via hole on the pad of NC Pin locations corresponding to SMT row female (or socket), strengthens the adhesive force of connector pad, makes to be not easy to tear off pad during plug.The utility model implements very convenient, can solve to a great extent when SMT row female (or socket) plugs by the problem torn off.
