Abstract

Disclosed is a socket connector, comprising an insulating body, a metal casing, and a plurality of terminals, wherein the insulating body is sleeved by the metal casing; the insulating body comprises a substrate, with the substrate extending forward to form a lingual plate; the substrate is provided with a plurality of accepting grooves; the lingual plate is provided with a plurality of plugging grooves communicated with the accepting grooves; the terminals comprise a basal part, a contact part, a pressure head part, and a welding tail, with the basal part contained in the accepting grooves and the contact part contained in the plugging grooves; the upside of the front end of the plugging grooves is provided with a reserved portion; the pressure head part of the terminals abuts against the downside of the reserved portion; and the welding tail is arranged outside the insulating body. The solder side of the HDMI socket connector is flat and can effectively prevent the terminals from tilting or withdrawing.

Description

The HDMI socket connector

Technical field

The utility model relates to a kind of connector, especially relates to a kind of HDMI socket connector.

Background technology

HDMI (High Definition Multimedia) promptly is a HDMI.The HDMI interface can provide the transfer of data broadband up to 5Gbps, can transmit the audio signal and the high definition video signal that do not have compression.Need not simultaneously to transmit advance capable D/A or mould/number conversion, can guarantee that the video-audio signal of first water transmits at signal.

When video-audio signal transmits, only need a HDMI line just can transmit video-audio signal simultaneously, and unlike needing many wire rods to connect now.When carrying out D/A or mould/number conversion, can obtain higher Voice & Video transmission quality.As far as the consumer, the HDMI technology can not only provide image quality clearly, adds audio/video and adopts unified cable, has simplified the installation of household audio and video system greatly.

In order to cooperate high-quality video-audio signal transmission wire, on many audio-visual electric equipment products, all can set up one group of HDMI connector, let the user can connect the HDMI transmission line and use.Traditional HDMI connector is made up of insulating body, metal shell and terminal usually, and the metal shell riveted is fixed in outside the insulator body, and terminal accommodating is in the accepting groove of insulating body.

Yet, but the terminal front end of this type of HDMI connector is exposed to outside the insulating body, the easy perk of terminal, and the rear portion of terminal is exposed to outside the insulating body hidden danger that has terminal to withdraw from.

The utility model content

The purpose of the utility model is to overcome deficiency of the prior art, provide a kind of solder side smooth, can effectively prevent terminal perk and the socket connector that withdraws from.

For reaching above-mentioned purpose; The utility model comprises insulating body, metal shell and plurality of terminals; Metal shell is sheathed on outside the insulating body, and insulating body comprises matrix, and said substrate extends to form hyoplastron forward; Offer some accepting grooves on the said substrate, offer some inserting grooves that are connected with accepting groove on the hyoplastron; Said terminal comprises base portion, contact site, pressure head portion and weldering afterbody; Said base portion is contained in the accepting groove, and said contact site is contained in the inserting groove, and the upper front end of said inserting groove is provided with reservation portion; The pressure head portion of said terminal presses on and reserves the subordinate, and the weldering afterbody places outside the insulating body.

Further, convex with draw-in groove on the said substrate, offer fixture block on the said metal shell, said fixture block snaps in the draw-in groove.

Further, the both sides, rear end of said metal shell are formed with concave fastening part.

Further, said insulating body and the terminal structure that is formed in one.

In sum, the terminal of the utility model is except that the weldering afterbody, and other parts are contained in the insulating body entirely, make things convenient for the location in the insulating body of terminal, and makes the solder side of weldering afterbody smooth; Pressure head portion presses on and reserves the subordinate, thereby can effectively prevent the front end perk of terminal; Metal shell does not have rivet clasp outside insulating body, and is simple in structure, low cost of manufacture.

Embodiment

For further understanding characteristic, technological means and the specific purposes that reached, the function of the utility model, the utility model is described in further detail below in conjunction with accompanying drawing and embodiment.

See also Fig. 1 to Fig. 3, the utility model socket connector comprises insulating body 10, metal shell 20 and plurality of terminals 30, and metal shell 20 is sheathed on outside the insulating body 10, and terminal 30 is located in the insulating body 10.Insulating body 10 and terminal 30 structure that is formed in one.

Insulating body 10 comprises matrix 11, and substrate 11 extends to form hyoplastron 12 forward, offers some accepting grooves on the substrate 11, offers some inserting grooves that are connected with accepting groove 121 on the hyoplastron 12, and the upper front end of inserting groove 121 is provided with reservation portion 13.Convex with draw-in groove 111 on the substrate 11; Offer fixture block 21 on the metal shell 20; Said fixture block 21 snaps in the draw-in groove 111; Thereby metal shell 20 is fixed on the insulating body 10, and the both sides, rear end of metal shell 20 are formed with concave fastening part 22, in order to reinforce the fixing power between metal shell 20 and the insulating body 10.

See also Fig. 4, terminal 30 comprises base portion 31, contact site 32, pressure head portion 33 and weldering afterbody 34, and base portion 31 is contained in the accepting groove, and contact site 32 is contained in the inserting groove 121, and pressure head portion 33 presses on reservation portion 13 times, and weldering afterbody 34 places outside the insulating body 10.

In sum, the terminal 30 of the utility model is except that weldering afterbody 34, and other parts are contained in the insulating body 10 entirely, make things convenient for the location in the insulating body 10 of terminal 30, and makes the solder side of weldering afterbody 34 smooth; Pressure head portion 33 presses on reservation portion 13 times, thereby can effectively prevent the front end perk of terminal 30; Metal shell 20 no rivet clasps are outside insulating body, and are simple in structure, low cost of manufacture.

The above embodiment has only expressed a kind of execution mode of the utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model scope.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection range of the utility model.Therefore, the protection range of the utility model should be as the criterion with accompanying claims.
