Description

Connector

Technical field

The utility model relates to junction cable, is specifically related to a kind of connector.

Background technology

On communication equipment, often to use junction cable and come the transmission trunking signal.When processing and manufacturing, generally adopt specific processing technology, the end of connector and cable is coupled together; During actual the use, connector one end links to each other with equipment, and the other end of cable links to each other with digital distribution frame, realizes the transmission and the switching of signal.According to the difference of using connector, junction cable has multiple implementation method, industry is used the more D connector that is, is mainly used in the Handle Bar outlet, also has to be used as the motherboard outlet.According to the difference of connector stitch spacing, the branch of high density junction cable and low-density junction cable is arranged.Adopt which kind of junction cable on earth, need to determine according to the specific product needs.

For junction cable, require that processing technology is good, installability is good, and along with the raising of product integrated level, also more and more higher to the density requirements of junction cable.In addition, the overall dimension of connector must meet the requirement of specific product.

Repeating signal need use symmetric double twisted wire (balance transmission) or coaxial cable transmission (non-equilibrium transmission), and one road repeating signal is realized by two pairs of twisted-pair feeders, and a pair of received signal that is used for a pair ofly is used to send signal; Perhaps one road repeating signal is realized by two coaxial lines, and one is used for received signal, and one is used to send signal.Like this, 16 road repeating signals need 32 pairs of twisted-pair feeders or 32 coaxial lines to realize, corresponding connector needs at least 64 pin positions, also needs suitably to increase earthy pin position in addition.

Having adopted in the prior art a kind ofly has the SCSI high density D connector of 50 pin positions to process junction cable, and every cable goes out 8 road repeating signals altogether, needs two cables could realize the transmission and the switching of 16 road repeating signals, referring to Fig. 1 and Fig. 2.Junction cable comprises connector 1, connector shell 2, hold-down screw 3, cable wire 4, connector pin 5.Connector afterbody shown in the figure in the junction cable adopts the form of straight outlet, can also adopt the form of oblique outlet to realize.

There is following shortcoming in prior art:

Shortcoming one: the junction cable that adopts prior art to design and produce, the stitch spacing of its adjacent contact pin 5 is 1.27 millimeters, spacing is too little, and each contact pin 5 all is fixed on the connector 1 in advance, cause contact pin 5 afterbodys to be connected adding man-hour very difficult with cable wire, no matter be to adopt welding procedure or employing compression joint technique, the cable reliability that processes is all poor, occurs problems such as loose contact easily.

Shortcoming two: the junction cable that adopts prior art to design and produce, because the spacing of a plurality of contact pins 5 is too little, when plugging operation, its contact pin 5 causes system's cisco unity malfunction than being easier to looper, broken needle.

Shortcoming three: the junction cable that adopts prior art to design and produce, because a cable can only go out 8 road repeating signals, when needs go out 16 road repeating signals, need to use two this cables, it is bigger to take up room, and has reduced the line density that of equipment.

The utility model content

The technical problems to be solved in the utility model is, a kind of connector is provided, and it is relatively poor to overcome existing connector processing difficulties, the connection reliability that is used for junction cable, occurs problems such as loose contact, looper, broken needle easily.

The technical solution of the utility model is as follows: provide a kind of, the 2mm connector that comprises 4 * 6 of at least 3 groups, also comprise a shell that described 3 groups 4 * 6 2mm connector can be included in together, constitute 4 * 18 2mm composite connector of exportable 16 road signals.

The utlity model has following advantage: constitute composite connector by the connector that adopts many group 2mm, the spacing of each contact pin is 2mm, after contact pin can machine earlier with the heart yearn of wire rod, insert in the connector again, easy to process, the reliability height by normal process processing, the phenomenon of loose contact can not occur.This connector plugs conveniently when mounted, looper, broken needle phenomenon can not occur.Only need a cable can go out 16 road repeating signals, adopt the integrated level of two cables higher than prior art, it is less to take up room, and has improved the line density that of equipment.

Embodiment

With reference to Fig. 3, Fig. 4, the utility model connector adopts 3 groups 4 * 6 2mm connector to form a whole, and forms one 4 * 18 2mm connector 6, and the pin tail of 2mm connector is with after cable wire 8 is connected, be fixed on package shell 7 the insides, form one 16 road junction cable.Wherein wire rod 8 can be that 32 pairs of twisted-pair feeders of 64 cores are used for balance transmission, also can be that 32 core coaxial cables are used for non-equilibrium transmission.

The afterbody of shell 7 also can adopt oblique outlet structure except can adopting straight outlet structure, as can be seen, be provided with oblique wire hole at the afterbody of shell 7 in Fig. 4, and the outlet direction of cable wire 8 becomes 35 ± 10 degree angles with vertical plane.Place, diagonal angle, the outside at shell 7 respectively is provided with a screw 3, plays fixation when cable is installed.

In Fig. 4, also marked putting in order and the naming method of each stitch 9 of each stitch 9 of this connector 6 end faces.According to the placement direction of connector 6 in Fig. 4, connector has 4 row, 18 hand-manipulating of needle pin, and horizontal direction is with small letter English alphabet a, b, c, d ordering, and vertical direction is with numeral 1 ~ 18 ordering.
