The utility model solves the problems that in the prior art, only eight channels of cables can be used for transmitting less than eight channels of relay signals, etc. by utilizing the relay cable assembly with 26 inserting pins to be specially used for transmitting four channels of relay signals.
Description
Technical field
The utility model relates to the cable technology in the electronics or the communications field, specifically refers to cable assembly.
Background technology
Repeating signal need use the transmission of symmetric double twisted wire (balance transmission) or co-axial cable component (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.
On communication equipment, often to use junction cable and come the transmission trunking signal.During processing and manufacturing, generally adopt specific processing technology, connector and cable are coupled together, form the junction cable assembly.During actual the use, an end links to each other with equipment, and the other end links to each other with digital distribution frame, realizes the transmission and the switching of signal.According to the difference of using connector, the junction cable assembly has multiple implementation method, industry is used the more D connector that is, is mainly used in the Handle Bar outlet, also can be used for the motherboard outlet.
The modern communications machine room uses the junction cable assembly in a large number.The equipment of the equipment of the difference in functionality of same equipment manufacturers, distinct device manufacturer etc. all might be placed on same machine room or same building.Like this, the profile of junction cable assembly, contact pin definition etc. are unified more, construct with regard to Vietnamese side just, and apparatus interconnection is just succinct more, and outward appearance is also good more.Simultaneously, the processing cost of manufacturer is also low more.
Prior art provides a kind of has the SCSI high density D connector of 50 contact pins to process the junction cable assembly, and its front view and end view are respectively referring to Fig. 1 and Fig. 2.It comprises shell 2, is fixed on the connector 1 in the shell 2, is fixed on the contact pin 5 in the connector 1, the hold-down screw 3 that 4, two on the cable that is connected with contact pin 5 places shell to be used for fixing.Prior art shown in the figure is the straight outlet form of connector afterbody, in actual the use form that adopts oblique outlet is arranged also.
The junction cable assembly that adopts prior art to design and produce generally transmits 8 road repeating signals with 50 contact pins, only needs transmission 4 road repeating signals in the reality sometimes, so generally all be that the junction cable assembly that adopts transmits 8 road repeating signals; Owing between each equipment manufacturers, between the different product of same manufacturer the contact pin of relay component all there is the definition mode of oneself, be that the contact pin signal does not have unified Definition in the relay component, and the different contact pins that different manufacturers also can use in 50 contact pins transmit 4 road repeating signals, therefore, not only bad for same serial communication products and the mutual usefulness of each communication product, also be unfavorable for the interconnection between each equipment to junction cable.For the less relay component of demand contact pin, 8 road junction cable assemblies are because its contact pin is more, the gap is less, so its processing technology more complicated, the reliability of finished cable assembly is poor.
The utility model content
The utility model provides a kind of junction cable assembly, and is relatively more chaotic and cause the problem of communication equipment interconnection difficulty to solve contact pin signal definition in the prior art.
For addressing the above problem, the utility model provides following technical scheme:
A kind of junction cable assembly comprises shell 2, is fixed on the connector 1 in the shell 2, is fixed on the contact pin 5 in the connector 1, the cable 4 that is connected with contact pin 5; Contact pin in the described connector is 26, and each contact pin links to each other with a lead in the cable 4 respectively, and described 26 contact pins divide three rows to arrange, and wherein two arranges and is respectively 9 contact pins, and another row is 8 contact pins.
Described 26 contact pins divide three to line up trapezoidal arrangement, and identical with trapezoidal direction shown in the connector ends.
The utility model is compared with prior art: be specifically designed to transmission 4 road repeating signals, be not used in the repeating signal of other way of transmission, so avoided the skimble-scamble problem of way of prior art transmission trunking signal; The utility model has carried out clear and definite definition to the signal of each contact pin, has unified the interface of the transmission and the switching of signal, helps the mutual usefulness of junction cable assembly, helps the interconnection of each equipment room; The utility model is owing to adopted 26 contact pins, and quantity is lacked than prior art, so pin spacing is bigger than prior art; Exactly because it is big that pin spacing becomes, and cause processing technology simpler than prior art, and the reliability of finished cable assembly is also than higher.
Description of drawings
Figure 1 shows that the junction cable assembly front view that uses the high density D connector;
Figure 2 shows that the junction cable assembly end view that uses the high density D connector;
Figure 3 shows that the utility model junction cable assembly front view;
Figure 4 shows that the utility model junction cable assembly connector end view.
Embodiment
The utility model constitutes 4 road junction cable assemblies by reducing contact pin quantity and corresponding structure, consult Fig. 3,4 road junction cable assemblies of the present utility model comprise: shell 2, be fixed on the connector 1 in the shell 2, be fixed on the contact pin 5 in the connector 1, the cable 4 that is connected with contact pin 5 is arranged on the screw 3 that is used for fixing on the shell 2.
Cable 4 can be that 8 pairs of twisted-pair feeders of 16 cores are used for balance transmission, also can be that 8 core coaxial cables are used for non-equilibrium transmission.Screw 3 plays fixation when cable assembly is installed.
As shown in Figure 4, the arranging situation of each contact pin 5 of connector 1 end face is as follows in the cable assembly:
According to the placement direction of connector 1 in Fig. 4, contact pin 5 minutes three row also arranges in echelon, and next row promptly has 9 contact pins near trapezoidal long limit, and a middle row also is 9 contact pins, and going up a row most is 8 contact pins near trapezoidal minor face promptly.
Contact pin number table among the figure is understood its ordering situation, next socket pin is followed successively by the first contact pin S1 to the, nine contact pin S9 by from right to left order, a middle socket pin is followed successively by the tenth contact pin S10 to the 18 contact pin S18 by order from right to left, go up most a socket pin and be followed successively by the 19 contact pin S19 to the 26 contact pin S26 by from right to left order, the signal definition of its transmission is as follows:
(1) per two of the first contact pin S1 to the, the eight contact pin S8 of next socket pin are one group, are used for received signal.
(2) going up per two an of contact pin of arranging most is one group, is used to send signal.
