Description

The quartzy plug of a kind of 8 lead-in wires

Technical field

The utility model relates to the Communication Equipment field, furthermore is the connector field, particularly a kind of 8 lead-in wire (8P) quartzy plugs.

Background technology

Along with the IT technology rapid development, as the comprehensive wiring system of network infrastructure and information transmission platform also at synchronized development, the six type routing standard of latest edition (Cat.6 standard) is exactly to release for the raising that adapts to network speed and the needs of spread bandwidth, and the development of whole industry has been produced very important influence.

The six type routing system is by constituting such as many assemblies such as cable, wire jumper, connectors.So intrasystem each parts, link and channel all should satisfy the Cat.6 standard, more should be like this as the quartzy plug (also claiming crystal head) of primary element.

At present popular prior art 8 lead-in wire (8P) quartzy plugs (claiming RJ45 connector again) be the quartzy plug (as shown in Figure 1, 2) of " four high four is low " formula that common bilayer misplaces one by one and arranges, also can place a lead-in wire (or claiming heart yearn) support 5 ' in its cuboid inner chamber, support is provided with the lead-in wire perforation that the two-layer dislocation one by one of height is arranged; In addition, the quartzy plug of 8P that allegedly also has a kind of monolayer alignment.The shortcoming of the quartzy plug of prior art 8P is to be mainly reflected on its structure, no matter be the former or the latter, because split the solving in heart yearn termination of wiring back pair twist grown (destruction pair twist), line between the distance less, parasitic capacitance is bigger, electromagnetic interference is comparatively serious, thereby causes the quartzy plug of prior art 8P to be difficult to satisfy the requirement of six type routing standard (Cat.6 standard) on NEXT (near-end crosstalk) and two important parameter indexs of RL (return loss).

Summary of the invention

Task of the present utility model is the defective that will overcome prior art, designs a kind of NEXT (near-end crosstalk) and RL (return loss) minimum of making, and can satisfy the quartzy plug of modified model 8 lead-in wires of up-to-date six type routing standard-required.

The technical solution of the utility model is as follows:

The quartzy plug of a kind of 8 lead-in wires, the lead-in wire location notch hole that is used for 8 lead-in wires are divided in proper order by setting the two-layer arrangement that misplaces corresponding to putting in order of gold plaque one by one of height that comprises 8 gold plaques that are arranged in order at hollow quartzy header body, its top and be positioned at the gold plaque top, the height of gold plaque is divided into two kinds of height, correspond respectively to the location notch hole of high-rise and low layer, it is characterized in that the order that described gold plaque is arranged from left to right by height is that the 1st, 3,7 gold plaques are high gold plaque, the 2nd, 4,5,6,8 gold plaques are low gold plaque; The height of described location notch hole is arranged and is arranged corresponding with the height of gold plaque.

Further improve and be: the inner chamber of described body is a cuboid, has one can fill in cuboid down-lead bracket in it from the body afterbody in inner chamber, and support is arranged by " ten " font and is provided with slotted eye.

The utility model has been done improvement to gold plaque and location notch hole and down-lead bracket on the structure, overcome the defective of the quartzy plugs of prior art 8 lead-in wires, make the heart yearn termination of wiring back pair twist split solve the shortest, line between distance bigger, parasitic capacitance diminishes, and electromagnetic interference reduces.A large amount of experiments shows that quartzy plug NEXT (near-end crosstalk) of the utility model 8P and RL (return loss) are improved, and have satisfied the six type routing standard of latest edition.

Below in conjunction with drawings and Examples the utility model is further described.

Embodiment

A kind of 8 lead-in wire quartzy plugs (shown in Fig. 3-5), by 8 gold plaques that are arranged in order 2 of hollow quartzy header body 1, below, its top, be positioned at gold plaque 2 tops be used for divide two-layer lead-in wire location notch hole 3 and the down-lead bracket of arranging 5 that misplace corresponding to putting in order of gold plaque 2 one by one of height to constitute in proper order by setting in 8 lead-in wires 4.

The inner chamber of body 1 is roughly cuboid, and the front end of inner chamber is facing to gold plaque 2 and lead-in wire location notch hole 3; The rear end open of inner chamber supplies down-lead bracket 5 and cable 11 to contain sheath and penetrates.

The height of gold plaque 2 is divided into two kinds, corresponds respectively to the high level and the low layer of location notch hole 3.The order that gold plaque 2 is arranged from left to right by height is that the 1st, 3,7 gold plaques are high (or saying long) gold plaque, and the 2nd, 4,5,6,8 gold plaques are low (or saying short) gold plaque; The height of location notch hole (3) is arranged and is arranged corresponding with the height of gold plaque.

Down-lead bracket 5 is a cuboid, matches with inner chamber 6 shapes of body 1, arranges by " ten " font on the support 5 and is provided with

slotted eye

7,8,9,10.Specifically, two

holes

7,8, centre of " ten " font slotted eye are " H " shape hole of upper and lower opening 71,81, and 9,10 top or bottom also are provided with opening 91,101 in hole, the left and right sides, and convenient lead-in wire 4 is filled in.

The utility model is the quartzy plug of a kind of RJ-45 of brand-new design, complete special processing different from the past has been made in arrangement to the high and low combined leads location notch hole 3 of gold plaque, add down-lead bracket and be the design of hard cross structure, make every lead-in wire (or saying heart yearn) position more reasonable, reduced to greatest extent line between distributed capacitance, reduced the magnetic interference between every pair of lead-in wire, thereby guaranteed that the quartzy plug of the utility model can reach up-to-date six type routing standard.

The utility model and cable core are (referring to the Fig. 5-7) that connects like this: 1, select to meet four couple (8 core) cable core 11 of six type routing standard, peel the sheath 12 (also claiming outer quilt) of one end off; 2, four pairs of lead-in wires 4 are outwards separated along soft cross 13 in the cable core 11, again four pairs of lead-in wires 4 are filled in the

slotted eye

7,8,9,10 from the opening 71,81,91,101 of hard support 5 by soft cross 13 original position, hole 7 ', 8 ', 9 ', 10 ' correspondences.3, the lead ends of pair twist is partly taken each apart (claiming to destroy pair twist again), smooth out with the fingers straight; 4, each is filled in body 1 to lead ends together with down-lead bracket 5, and make each the corresponding location notch hole 3 that respectively goes between that inserts of lead ends; 4, last, with crimping tool gold plaque is punctured and to be pressed into each lead-in wire, just can make each lead-in wire high and low low by 1,3,7 lead-in wires from left to right corresponding to gold plaque, the high sequence arrangement of 2,4,5,6,8 lead-in wires reaches the purpose that reduces cross-talk and return loss.

Adopt that the benefit of the down-lead bracket of hard cross structure has three: 1, each is fixed in the corresponding groove lead-in wire, ruined pair twist part (particularly 36 pairs and 45 pairs of lead-in wires) is the shortest during separated time, can reduce cross-talk and return loss.2, line between distance increase, the big more line capacitance of distance is more little, thereby reduces near-end crosstalk (NEXT).3, more convenient in the operation, lead-in wire is fixed can be not messy yet, and the plug lead-in wire is more smooth.

The utility model is equally applicable to short body crystal head.
