Abstract
The utility model relates to the technical field of an electric connector, and especially relates to an anti-insertion-back structure of a board-to-board connector. Downward-protruding clamping portions are arranged on the lower side of the front of the connector, and the clamping portions are abutted against the board end of a PCB. The direction of the force upon the clamping portions by the PCB is opposite to the direction of the force upon the connector by insertion thrust, thereby increasing the holding force of the connector corresponding to the PCB and preventing the connector from contracting inward or tilting corresponding to the PCB. According to the utility model, the fixed feet of the connector are effectively protected, the connector is ensured to be inserted or unplugged normally, and the service life of the connector is prolonged. The anti-insertion-back structure of a board-to-board connector is of a simple structure, scientific and reasonable, convenient in assembly, low in investment cost, and enables the practicality of the board-to-board connector to be greatly improved.
Description
Technical field
The utility model relates to technical field of electric connectors, and especially fingerboard connects electric connector.
Background technology
Convention, electric connector have promptly inserts the effect of promptly pulling out, and is able to extensive use at present.Electric connector is divided into by the assembling connected mode that line connects electric connector and plate connects electric connector.Plate connects electric connector and normally installs near the plate end place of pcb board, and only relies on fixing feet and tin pin to be fixed on the pcb board, and effectively fixing for connector spigot is lacked usually; Make supporting joint outer part when inserting; Because to inserting the effect of thrust, plate often occurs and connect in the relative pcb board of electric connector and contract or perk, tracing it to its cause is that the relative pcb board of connector can be moved back or start by the top when inserting at line end because of its retain strength is too small; Influence normal plug work, even can't re-use.
For this reason, the applicant is because above-mentioned convention plate connects the defective of the mounting structure of electric connector, and the spirit of adhering to the research innovation, keeping on improving is utilized its professional eye and professional knowledge, and the anti-plug that works out a kind of plate connecting connector is moved back structure.
Summary of the invention
It is a kind of simple in structure, scientific and reasonable that the purpose of the utility model is to provide, and it is convenient to implement, and cost of investment is low, effectively prevents to contract in the relative pcb board of connector or the anti-plug of the plate connecting connector of perk is moved back structure.
For achieving the above object, the utility model adopts following technical scheme:
The anti-plug of plate connecting connector is moved back structure, before connector, holds downside to be provided with down protruding card division, and the card division is against the plate end of living pcb board; The card division receives the direction of pcb board active force and this connector to receive to take this to prevent to contract or perk in the relative pcb board of connector to inserting the in the opposite direction of thrust.
Said card division is that the lower side front end by shell outside the connector turns down moulding downwards.
Protruding terminal concordant or exceed the following bottom side of pcb board under the said card division.
End protruding under the said card division is formed with gib head, and gib head colludes the following bottom side into pcb board.
The utility model is to hold before the connector downside to be provided with protruding card division down, and the card division is against the plate end of living pcb board, not only provides good in support; Make plug stronger; But also through pcb board effect card division resist connector suffered to inserting thrust, prevent to contract or perk in the relative pcb board of connector thereby reach, effectively protect the fixing feet of connector; Ensure the normal plug work of connector, increase the service life.
The utility model advantage again is simple in structure, and is scientific and reasonable, and assembling is implemented convenient, and cost of investment is low, greatly the practicality of riser connecting connector.
Description of drawings:
Accompanying drawing 1 is the utility model one of which preferred embodiment structural representation;
Accompanying drawing 2 is that sketch map is used in the structure assembling back of Fig. 1;
Accompanying drawing 3 is its two preferred embodiments structural representation of the utility model;
Accompanying drawing 4 is the structure assembling sketch map of Fig. 3.
Embodiment:
Below in conjunction with accompanying drawing the utility model is further specified:
Consult Fig. 1,2,3, shown in 4; System is the preferred embodiment structural representation of the utility model; The utility model is that the anti-plug of relevant plate connecting connector is moved back structure, before connector 10, holds downside to be provided with down protruding card division 11, and card division 11 is against the plate end of living pcb board 20; Card division 11 receives the direction of pcb board 20 active forces and this connector 10 to receive to have increased the retain strength of connector 10 relative pcb boards 20 to inserting the in the opposite direction of thrust, takes this to prevent to contract or perk in the connector 10 relative pcb boards 20.
In the present embodiment, card division 11 is that the lower side front end by shell outside the connector 10 turns down moulding downwards; Protruding terminal concordant in card division 11 times or exceed the following bottom side of pcb board 20.Fig. 1, shown in 2, card division 11 is relative connector 10 ports lamellar bodies vertically downward, the plate end of the pcb board 20 that vertically reclines; Play thrust function, promptly connector 10 receives inserting thrust, and card division 11 is against the plate end of living pcb board 20; Prevent to contract in the connector 10 relative pcb boards 20; Even and the component on producing tiltedly when inserting, the face friction between the plate end of card division 11 and pcb board 20 can be resisted the component on oblique equally, prevents connector 10 relative pcb board 20 perks; Thereby effectively protect the fixing feet of connector, avoid fixing feet to be damaged, ensure the normal plug work of connector, increase the service life.
Fig. 3, the 4th further increases structural design on the basis of Fig. 1, the instance shown in 2, promptly 11 times protruding ends are formed with gib head 111 in the card division, and gib head 111 colludes the following bottom side into pcb board 20.At this moment, the vertical abutment face of card division 11 plays the effect of the foregoing description, and gib head 111 colludes the following bottom side into pcb board 20, makes card division 11 tightly fasten pcb board 20, and the anti-effect of sticking up is better.
The anti-plug of the plate connecting connector that the utility model provides is moved back structure, and simple in structure, scientific and reasonable, cost of investment is low, and simple and convenient assembly, has improved the assemble stable property and the utilization structure property of plate connecting connector greatly.Certainly, more than diagram is merely the utility model preferred embodiments, is not the scope of application that limits the utility model with this, so every on the utility model principle, making in the protection range that equivalent change all should be included in the utility model.
