Abstract
The utility model discloses a wiring terminal which is applied to a socket correspondingly used with a finger; the finger socket terminal comprises a pressure line part and a contact part; the contact part is provided with an arch-shaped elastic part which protrudes upwards; a position on the contact part body which corresponds to the tail end of the elastic part is provided with an anchor ear; and the tail end of the arch-shaped elastic part is arranged in the anchor ear. The finger socket terminal hoops the tail end of the elastic part with the anchor ear, so that the elastic part produces pre-pressure before being inserted into a PCB; and after the PCB is inserted in, the elasticity is increased, and the contact is tighter.
Description
Technical field
The utility model discloses a kind of binding post, the binding post on particularly a kind of socket that is applied to corresponding use with golden finger.
Background technology
Along with the application of electronic product in people life more and more widely, the electronic product accessory has also obtained very big development.At present, the development of electronic product just develops towards summary, modularization direction, and in the prior art, modular electronics produces sheet, being connected between module and the module all is that the most frequently used is provided with socket with exactlying on motherboard by the mode of pegging graft, and correspondence is provided with one and arranges golden finger on the functional module plate, during use, the pcb board that will have golden finger is inserted into interior the getting final product of corresponding socket of motherboard.The interface unit that generally adopts on the motherboard socket is exactly a binding post, please referring to accompanying drawing 1 and accompanying drawing 2, connection terminal structure of the prior art is as shown in Fig. 1 and Fig. 2, terminal is divided into the two large divisions, the terminal rear end is the coupling part, be used for being connected with socket, front end is a bow-shaped shrapnel, be used for being connected with golden finger elasticity, present splicing ear bow-shaped shrapnel part all is to be in the cantilever free state, and when golden finger inserted, arc elastic part elastic force was limited, therefore cause loose contact easily, and cause quality problems.
Summary of the invention
Be the cantilever free state at the above-mentioned golden finger socket shell fragment of mentioning of the prior art, elastic force is limited, cause the shortcoming of quality problems easily, the utility model provides a kind of new golden finger socket terminal, and it is provided with anchor ear at the elastic part end, with golden finger terminal this in anchor ear, make the elastic part on the terminal that precompression arranged when golden finger does not insert, pressure is bigger after golden finger inserts, and contact performance is better, and stability is stronger.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of golden finger socket terminal, comprise interconnective line ball part and contact portion, contact portion is provided with the arc elastic part to upper process, on the main body of contact portion corresponding to arc elastic part terminal position, be provided with anchor ear, arc elastic part end is provided with in the anchor ear.
The technical scheme that its technical problem that solves the utility model adopts further comprises:
Opposite side corresponding to elastic part one side on the main body of described contact portion is provided with the spacing tongue of upwards turning up.
Be provided with the limited step that is upturned corresponding to elastic part one side on the main body of described contact portion, limited step setting and arc elastic part rear end.
Described arc elastic part has been arranged side by side two.
The beneficial effects of the utility model are: the utility model adopts anchor ear that the elastic part end is waled, make elastic part of the present utility model produce precompression under the situation of pcb board not inserting, after pcb board inserts, make its elasticity bigger, contact tightr.
Below in conjunction with the drawings and specific embodiments the utility model is described further.

Embodiment
Present embodiment is the utility model preferred implementation, and other all its principles are identical with present embodiment or approximate with basic structure, all within the utility model protection range.
Please referring to accompanying drawing 3 to accompanying drawing 9, the utility model is that whole punching press forms, and artificially it is defined as two parts, i.e. line ball part 1 and elastic part 2, elastic part 2 is defined as the utility model the place ahead, line ball part 1 is defined as the utility model rear.Please in conjunction with referring to accompanying drawing 5, accompanying drawing 7 and accompanying drawing 8, in the present embodiment, line ball part 1 front end master looks is rectangle, line ball part 1 rear end is main look triangular in shape, the cross section of line ball part 1 front-end and back-end all is " U " shape, during use, with wire bonds in the groove of " U " shape line ball part 1, the wing of line ball part 1 both sides is inwardly depressed, closed up, lead and the utility model can be fixedly installed togather.Please referring to accompanying drawing 6, in the present embodiment, elastic part 2 back end main body 5 cross sections are rectangle, by among Fig. 6 as can be known, main body 5 is that from top to bottom symmetry compacting forms, the both sides, bottom are respectively equipped with the shell fragment to outer process, shell fragment rear end and main body 5 are wholely set, and the terminal perk of rear end forms a limited step 8, when inserting the plastic cement matrix, play the role of positioning, prevent to insert excessively.Main body 5 close fore-ends are provided with the spacing tongue 6 to upper process, and spacing tongue 6 adopts impact styles, makes spacing tongue 6 parts to upper process, also plays the role of positioning, and when pcb board in the use inserts, prevents that the utility model from falling back from matrix.Top, main body 5 the place ahead is provided with the anchor ear 4 of annular, and the shell fragment front end of elastic part 2 is arranged in the anchor ear 4, is blocked by anchor ear 4, make that when not using elastic part 2 has had precompression, can be when having pcb board to insert, elastic part 2 pressure are bigger, and contact is better.
Please referring to accompanying drawing 10, the utility model is gone up symmetry at matrix (not drawing among the figure) and is fitted with the utility model in use, and two shell fragments are inwardly corresponding, and when pcb board 9 inserted, extruding elastic part 2 made elastic part 2 that deformation take place.Because elastic part 2 of the present utility model has produced precompression before use, when pcb board 9 inserted, the elastic force of elastic part 2 more strengthened, and contacts tightr.
