Description

The high frequency connectors terminal

Technical field:

The present invention relates to a kind of connector of realizing that circuit connects and changes, the high frequency connectors terminal that especially a kind of high-frequency circuit top-stitching is used connector for substrate.

Background technology:

In the prior art, electric connector is to realize that circuit connects and the electromechanical compo of conversion, it is a kind of separable electric contacts, electric connector generally is made up of contact, insulator, shell, contact is made up of pin terminal and socket terminal, socket terminal is the vital part of contact, its relies on elastic construction when plugging together with contact pin strain to take place and produces elastic force and form tight the contact with contact pin contacting piece, finish connection, promptly realize being connected and disconnection of circuit by the contact between pin terminal and the socket terminal.In recent years along with growth in the living standard, computer, communication and consumption electronic products significantly improve for the requirement of message transmission capacity and signaling rate, to high power capacity, high frequency, multifunctional direction evolution, particularly in High-Speed PCB and the system design, the high-frequency signal line, the pin of integrated circuit, bonder terminal all may become the electromagnetic interference source, the electric connector of existing market supply still can't satisfy this requirement, scientific and technical personnel are also seeking novel electric connector terminal always, reduce the various factors that may become mutual interference source as much as possible, guarantee that whole system can operate as normal.

The utility model content:

The purpose of wood invention is to provide a kind of high frequency connectors terminal with the advantages of good shielding performance that can reduce electromagnetic interference at the prior art weak point.

The objective of the invention is to realize by following measure: the high frequency connectors terminal, its special character is, comprising:

A. several terminal bodies that form by the foil punching press, rounded opening is horn-like on its terminal bodies head, the head lower end is rectangular aperture and extends outward galianconism, head forms " L " type inner chamber, the head lower body is a neck, and what link to each other successively with neck is clamping 1, clamping 2, clamping 3 and clamping 4;

B. the insulator that matches with head " L " type inner chamber, the insulator inner chamber is a circular upper part and square lower part;

C. female terminal has the rectangular flat body, and the platysome middle part protrudes upward a pair of elastic arm, the contact site that platysome has downward bending to extend;

Insulator is installed in terminal bodies head " L " type inner chamber, and female terminal is installed in the insulator, terminal bodies ground connection or be connected on the circuit board reference potential.

Can also take following measure:

On the horn body of the rounded opening in described terminal bodies head upper end two breach are arranged, the center angle of described two breach is 68 °.

The salient point of described terminal bodies clamping 2, clamping 3, clamping 4 oriented nip side evaginations.

Described insulator has the strip shape body of 1,2 of clampings of extending to terminal bodies side clamping 1 direction, and its width is greater than the contact site width of female terminal.

The contact site that described female terminal platysome has downward twice bending to extend.

Compared with prior art, the utility model adopts between terminal bodies and female terminal insulator is installed, terminal bodies is separated with the female terminal circuit, terminal bodies ground connection or be connected on the circuit board reference potential, terminal bodies plays good shielding action like this, can weaken the counteracting electromagnetic interference with imitating, guarantee the operate as normal of each subsystem in the native system.The utility model can be widely used in fields such as communication, computer, consumer electronics product device and industrial automation.

Fig. 3 (e) is the terminal bodies front view, (f) is the terminal bodies end view.

Fig. 4 (e) front view that has been socket end (f) is the female terminal end view.

Embodiment:

Below in conjunction with accompanying drawing embodiment is elaborated:

In an embodiment of the present utility model shown in Figure 1, the high frequency connectors terminal, comprise: several terminal bodies a that forms by the foil punching press, rounded opening is horn-like on its terminal bodies head g, this plug energy automatic centering feasible and the connector another terminal Plug pin patch bay that the utility model connects, breach h on it plays the role of positioning, the center angle of two breach is 68 °, described breach guarantees that over against the projection of the connector another terminal Plug pin patch bay that connects with the utility model connection between the two is tight.Terminal body head lower end is rectangular aperture and extends outward galianconism that head forms " L " type inner chamber; Insulator b profile matches with " L " inner chamber, be installed in " L " chamber, insulator b has the bar shape of 2 of clamping of extending downward 1 and clampings to the terminal bodies side, the width of described bar shape is greater than the contact site width of female terminal c, the inner chamber circular upper part and square lower part of insulator b, the a pair of elastic arm 8 of female terminal c is installed in going up in the circle inner chamber of insulator b, and the platysome 9 of female terminal c is installed in the inner chamber of insulator b below, can prevent that like this female terminal c from rotating at insulator b; The contact site 10 that female terminal c platysome has downward twice bending to extend more helps the grafting with coaxial cable copper body; When on coaxial cable, the high frequency connectors terminal being installed, earlier coaxial cable end is cut off plastic wrappage by the high frequency connectors terminal sizes, expose solid copper body, insulating barrier, mesh shields layer successively respectively; Then coaxial cable solid copper body is inserted in the gap of the dull and stereotyped bending contact site 10 downwards of female terminal and dull and stereotyped 9, after confirming that the solid copper body puts in place, next step is clamped in clamping 3 on the mesh shields layer of concentric cable, at last clamping 4 is clamped on the plastic wrappage of concentric cable, after finishing this step, again the terminal bodies head is spent in neck i bending 90, the terminal bodies head is embedded in the clamping 1, the galianconism of again clamping 2 bendings being embraced terminal bodies head lower end and being rectangular aperture and extend outward, so just female terminal c shielding in terminal bodies a; The terminal bodies head is behind neck bending 90 degree, the platysome of female terminal c and contact site clamp the solid copper body of coaxial cable, simultaneously the bar shape width that extends under the terminal bodies side direction because of insulator b is greater than the contact site width of female terminal, therefore terminal bodies is still kept apart with female terminal, keep the good insulation performance state, ground connection by the connector another terminal Plug pin patch bay that connects with the utility model or be connected on the reference potential of wiring board, electromagnetic field with transmission signals all is limited in screen inside like this, outwards the width of cloth is not penetrated, same external electromagnetic field can not pass screen and enter inside, can prevent from effectively to weaken the electromagnetic interference of offsetting the high-frequency pulse signal generation by such mode, guarantee the operate as normal of each subsystem in the native system.

The salient point of described terminal bodies clamping 2, clamping 3, clamping 4 oriented nip side evaginations, salient point make each one of concentric cable line that is held tightr.

The above embodiments have provided the minimum unit of high frequency connectors terminals, and the staff of this area can make up within the scope of the appended claims according to actual needs, make distortion or modification.
