Abstract
The invention discloses a wire connecting terminal applied to a socket used corresponding to a golden finger, which comprises a wire pressing part and a contact part which are connected mutually, wherein the contact part is provided with an upward protruding arch elastic part; a main body of the contact part is provided with an anchor ear corresponding to the tail end of the arch elastic part; and the tail end of the arch elastic part is arranged in the anchor ear. The wire connecting terminal adopts the anchor ear to hoop the tail end of the elastic part, so that the elastic part already generates preliminary pressure under the condition that a PCB board is not inserted; and after the PCB board is inserted, the elasticity of the elastic part is stronger and the contact is closer.
Description
Technical field
The present invention 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 invention provides a kind of new golden finger socket terminal, it is provided with anchor ear at the elastic part end, and the golden finger end is located in the 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 the present invention solves its technical problem employing 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, is provided with the limited step that is upturned corresponding to elastic part one side on the main body of described contact portion, and limited step is arranged at arc elastic part rear end.
The technical scheme that the present invention solves its technical problem employing 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 turning up downwards.
Described arc elastic part has been arranged side by side two.
The invention has the beneficial effects as follows: the present invention adopts anchor ear that the elastic part end is waled, and makes elastic part of the present invention produce precompression under the situation of pcb board not inserting, and after pcb board inserts, makes its elasticity bigger, contacts tightr.
The present invention will be further described below in conjunction with the drawings and specific embodiments.

Embodiment
Present embodiment is the preferred embodiment for the present invention, and other all its principles are identical with present embodiment or approximate with basic structure, all within protection range of the present invention.
Please referring to accompanying drawing 3 to accompanying drawing 9, the present invention 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 place ahead of the present invention, line ball part 1 is defined as rear of the present invention.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 present invention 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 present invention 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 present invention goes up symmetry at matrix (not drawing among the figure) and is fitted with the present invention 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 invention has produced precompression before use, when pcb board 9 inserted, the elastic force of elastic part 2 more strengthened, and contacts tightr.
