Separate television at least needs display screen and main frame, needs to carry out signal by electrical connector between display screen and main frame With the transmission of voltage, but with the lifting of user's request quality, required transmitted data amount increase, is electrically connected between display screen and main frame Fitting inside conductor quantity and its PIN number can also increase therewith.If handling arrangement mode by traditional wire, i.e., signal wire is entered The twisted shielding processing of row differential pair, adjunction ground wire processing is carried out to supply lines, then the signal wire after processing and supply lines is horizontal The processing arrangement mode of arrangement, the electrical connection that electrical connector can be more and more thicker with the increase of PIN number and number of conductors, excessively thick Part is not only brought using upper inconvenience to user in actual use, and form is also unsightly, is unfavorable for lifting client couple The satisfaction of product.

Utility model content

Part in view of the shortcomings of the prior art, the purpose of this utility model are that providing a kind of transmission high speed that is used for believes Number and voltage electrical connector, be applicable to the transmission of a variety of high speed signals and voltage, and especially suitable for Split TV set The transmission of high speed signal and voltage between display screen and main frame, transmission high speed signal and voltage disclosed in the utility model are electrically connected Fitting is the arrangement by improving its inner lead, in electrical connector inner lead increase, reduces the increase of its outward appearance thickness Amount.

The purpose of this utility model is achieved through the following technical solutions：

It is a kind of to be used to transmit the electrical connector of high speed signal and voltage, multiple conducting wires are laid with along its length inside it, The wire comprises at least differential signal line, supply lines, electric wire and shielding line, it is characterised in that

The electrical connector includes multiple signal line groups and multiple supply lines groups, the signal line group and the supply lines group It is arranged in parallel along the electrical connector length direction；

By an electric wire and at most, five groups of cell signal line groups are formed the signal line group, in the signal line group The cell signal line group and the electric wire are brought into close contact arrangement and surround cylindrical shape；

The cell signal line group is formed after being mutually twisted by two differential signal lines and a shielding line；

By two electric wires and at most, three supply lines are formed the supply lines group；

Further, it is provided with integument outside the supply lines group, the integument is by the electric wire and the power supply Line tight.

Further, the supply lines quantity in the supply lines group is three, and three supply lines are in positive three Triangular arrangement, the electric wire are laid in the gap of the supply lines and the integument.

Further, the cell signal line group is coated with insulative pipe sleeve.

Compared with the prior art, its advantage is the utility model：, can be significantly in electrical connector inner lead increase Degree reduces the incrementss of electrical connector outward appearance thickness, while the transmission demand of larger data amount is met, provides the user one Kind outward appearance is more very thin, and form is more graceful and uses more convenient electrical connector, while reduces life to a certain extent Produce cost.

Embodiment

The utility model is described in further detail with reference to embodiment：

As shown in Figures 1 and 2, traditional electrical connector is to the arrangement mode of the wire of its inside：After shielding processing Each wire group using two or one group as a row, transverse horizontal arrangement, if so resulting in by the limitation of the width of electrical connector When within the specific limits, its internal number of conductors laid may not reach quantity required, if with this traditional electrical connector When transmitting the signal of larger data amount, then the electrical connector width can be caused wide, be not easy to actually use, and also unsightly.

As shown in Figures 3 to 5, the inner lead of electrical connector of the present utility model is divided into signal line group and supply lines group, It is that signal line group and supply lines group is arranged in parallel along electrical connector length direction when laying inner lead.Wherein, two electricity Sub-line 3 and at most three supply lines 4 form a supply lines group, and supply lines group outside is provided with integument, electric wire 3 and power supply Line 4 is wrapped layer tight；By an electric wire 3 and at most, five groups of cell signal line groups 12 form one signal line group, letter Cell signal line group 12 and electric wire 3 are brought into close contact arrangement and surround cylindrical shape, one of cell signal line in number line group Group 12 is made up of two differential signal lines 1 and a shielding line 2, and two differential signal lines 1 in cell signal line group 12 and A piece shielding line 2 is mutually twisted, and insulative pipe sleeve is also enclosed with outside cell signal line group 12.

As preferable, two electric wires 3 and three supply lines 4 are laid in a supply lines group, three supply lines 4 are in just Rounded projections arranged, electric wire 3 are laid in the gap of supply lines 4 and integument；An electric wire 3 is laid in one signal line group With five groups of cell signal line groups 12, electric wire 3 and cell signal line group 12 are brought into close contact arrangement and surround cylindrical shape.

It should be noted that as shown in FIG. 6 and 7, when 12 groups of numbers of cell signal line group are less than five groups in signal line group, Cell signal line group 12 and electric wire 3 surround cylindrical shape with that can be brought into close contact arrangement with a ground wire 5 in the signal line group.

Embodiment

It is when setting number of conductors in electrical connector of the present utility model as 114 as shown in FIG. 6 and 7, corresponds to Its interface PIN quantity be 114, now, four groups of supply lines are laid with electrical connector of the present utility model Group, six groups of signal line groups, wherein five groups of signal line groups are formed by five groups of cell signal line groups 12 and an electric wire 3；It is remaining One group of signal line group is made up of four groups of cell signal line groups 12 and an electric wire 3, and four in the signal line group group unit Signal line group 12 and an electric wire 3 and a ground wire 5 are brought into close contact arrangement and surround cylindrical shape.Electrically connected compared to tradition The laying mode of part inner lead, will two wires be one group of overlapping arrangement, electrical connector improvement of the present utility model is： Wire is divided into different classes of wire group according to classification, while has longitudinally increased the overlapping quantity of wire, and reduces and respectively leads Gap between line so that horizontally arranged wire group and number of conductors reduce more than half.The very big journey of width of electrical connector On degree depend on its inner horizontal arrangement wire group quantity, therefore set inside number of conductors it is certain on the premise of, utilize this practicality The electrical connector of new wire arrangement mode compared with the electrical connector that conventional wires are arranged, its width reduction half with On, visually also allow user substantially to feel that electrical connector becomes very thin, and with the progress and development of science and technology, equipment With equipment room needed for the data volume transmitted also increasingly increase, then the practicality of electrical connector of the present utility model will just obtain more It is obvious to embody.

Preferred embodiment of the present utility model is the foregoing is only, it is all at this not to limit the utility model All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model Protection domain within.
