The RJ pin connector

[technical field]

The utility model relates to a kind of RJ pin connector, relates in particular to a kind of RJ pin connector that is used for high-transmission.

[background technology]

The RJ45 connector that the TaiWan, China patent announcement of announcing on July 11st, 2005 discloses a kind of high transmission speed M270549 number; In order to a kind of electric power connector plug (Plug) that meets the 6th type of communication standard (Category 6) to be provided; This plug is to be made up of plug body leading portion and plug body back segment; Wherein the plug body leading portion is equipped with compositions such as several conducting terminals, several trunking passages, carrier, elastic fastening plate, and the line that directly will manage into row is to inserting in the trunking passage; Plug body back segment outside is provided with slotted eye, groove, grab, groove and fixed block etc.; Inside is provided with an importing space and passes through in order to the netting twine that holds not strip off; With four pairs of twisted-pair feeders (Twisted Pair) stagger arrangement in the netting twine in carrier and trunking passage on the Different Plane; Utilize snap fastener to be combined into one, be pressed into line to fixing with conducting terminal insertion end pilot trench internal fixation twisted-pair feeder and by the rear fixed block after two sections combinations.Yet to offer spacing bigger owing to be used for trunking passage that twisted-pair feeder passes through, and it is just far away that two twisted-pair feeders are opened distance, is easy to generate cross-talk, influence the stability that signal transmits.

Therefore, need a kind of RJ pin connector that can address the above problem.

[utility model content]

The purpose of utility model is to provide a kind of RJ pin connector that can reduce cross-talk.

The purpose of the utility model realizes through following technical scheme: a kind of RJ pin connector; Comprise header body and be contained in the metal insert of header body; Be assembled in the plug Embedded Division in the header body and be undertaken in the plug Embedded Division and with metal insert electrically connect some to twisted-pair feeder; Said plug Embedded Division comprises base portion; From two foots that base portion extends back and the connecting portion that connects two foots, said connecting portion is provided with adjacent draw-in groove, and said twisted-pair feeder a pair of is contained in behind the draw-in groove located adjacent one another.

Compared with prior art, the utlity model has following beneficial effect: can shorten the draw-in groove of opening distance of twisted-pair feeder through on the RJ pin connector, being provided with, thereby can reduce cross-talk, improve the stability of signal transmission.

[embodiment]

See also Fig. 1 to shown in Figure 5; The utility model RJ pin connector 100 meets the 6th type of communication standard (Category 6); Comprise header body 1; Be contained in the metal insert 2 of header body 1, the cable 4 that is assembled in the plug Embedded Division 3 in the header body 1 and is undertaken in plug Embedded Division 3 and electrically connects with metal insert 2.

See also Fig. 2 to shown in Figure 3; Header body 1 is the single type moulding, and cross section is stepped, and its upper surface is provided with the elastic fastening plate 10 of control and butt connector plug; The front portion, lower surface offers some slots 11, and number of metal inserted sheet 2 is contained in the slot 11 from header body 1 lower surface.Header body 1 rear end face caves in forward and is provided with the host cavity 12 that communicates with slot 11.

Elastic fastening plate 10 comprises the projection portion 101 that protrudes out header body 1 front end face and the upwardly extending elasticity press section 102 that tilts.Projection portion 101 upper surfaces are provided with the bayonet socket 1011 that is used to hold butt connector, and bayonet socket 1011 disengagings hold when push downwards elasticity press section 102, thereby RJ pin connector 100 breaks away from butt connectors.

Plug Embedded Division 3 is from the assembling of the rear end face of header body 1 and be contained in the host cavity 12 of header body 1, and it comprises base portion 30, extends back and two foots 31 of symmetric arrangement and connect the connecting portion 32 of two foots 31 from base portion 30.Base portion 30 lower surfaces have inserts in the host cavity 12 and first trunking 301 and second trunking 302 that communicate with said slot 11; The depth difference and second trunking 302 of first trunking 301 and second trunking 302 are opened in respectively between two first trunkings 301, and first trunking 301 and second trunking, 302 bottom surfaces are respectively equipped with holding slot 3011 and 3021.Connecting portion 32 laterally near trunking and connect two foots 31 and connecting portion 32 in the middle of be provided with two adjacent draw-in grooves 320, upper surface and said first trunking 301 and second trunking 302 that draw-in groove 320 is opened in connecting portion 32 are opened in different plane.

See also Fig. 4 to Fig. 5, cable 4 comprises four pairs of twisted-pair feeders, is arranged on the plug Embedded Division 3 interior Different Plane.Twisted-pair feeder is divided into two rows, on arrange a pair of twisted-pair feeder 41, three pairs of twisted-pair feeders 42 of following row.

During assembling, at first with 41,42 strip ofves of four pairs of twisted-pair feeders, on arrange twisted-pair feeder 41 and before second trunking 302 of packing into, be fastened in earlier in the two adjacent draw-in grooves 320 of connecting portion 32 and still keep adjacent states.To arrange four pairs of twisted-

pair feeders

41,42 more up and down passes first trunking 301 and second trunking 302 of plug Embedded Division 3 and is immobilizated in

holding slot

3011,3021 respectively.Then plug Embedded Division 3 is assembled in the header body 1 with four pairs of twisted-pair feeders, last, metal insert 2 be fit into puncture in the slot 11 four pairs of twisted-pair feeders and with its electric connection.

Prior art RJ pin connector go up a pair of twisted-pair feeder of row because two holding slot spacings are bigger, thereby cause row's twisted-pair feeder to open spacing big closely related and produce the accumulative total cross-talk and superpose with row's twisted-pair feeder down, influence the signal transmission performances.And at the utility model RJ pin connector 100, thereby when be provided with at plug Embedded Division 3 two draw-in grooves 320 located adjacent one another can shorten on two of rows strip off twisted-pair feeder 41 open distance, can obviously improve the cross-talk high frequency performance, improve the stability of product.The structure of the utility model RJ pin connector 100 is equally applicable to the 7th type of communication standard (Category7).
