Description

The communications connectors plug

The utility model relates to a kind of communications connectors plug, and it is applied to various communication transmission systems, can dispose for communication stamen line, and can be installed on the communications connectors, is meant a kind of plug that is applied to the communications connectors of high speed transmission system especially.

It is very general to utilize network communication system to transmit data in recent years, and range of application is increasingly extensive, and along with the requirement of network communication system high-transmission efficient, not only the quality requirement of connecting line is more and more higher, along with transmission speed is more and more faster, also more and more rigorous for the quality requirement of telecommunication connector.Generally speaking, actual network communication path is made of transmission medium and telecommunication connector, and transmission medium can be twisted-pair feeder (Twisted Pair), coaxial cable (CoaxialCable), optical fiber (Optical Fiber) etc., yet how many above-mentioned network communication paths still has some defectives, makes the signal quality worsen along with the raising of network communication system frequency.

For the foregoing reasons, (the Electronic IndustriesAssociation of U.S.'s electronics industry association; EIA) with (the Telecommuication IndustryAssociation of telecommunications industry association; TIA) institute's release standard is subjected to the favor of IEEE, therefore the EIA/TIA568 standard is put in the standard of 802.3 μ, requires every numerical value of each transmission medium and connector assembly simultaneously for standard compliant, to be classified within standard.As the 3rd class (Category3) is so-called voice grade circuit, uses 24AWG solid wire and 100 Ω impedances, and frequency range can reach 10Mbps; The 4th class (Category4) is identical with the 3rd class, but frequency range can reach 16Mbps; The 5th class (Category5) is identical with the 3rd class, but frequency range can reach 100Mbps.Also have 5e class line standard in addition, discontinuous at the impedance of transmission medium, cause producing the requirement for restriction of reflex institute loss power, also, more be strict in the 5th class promptly at the standard-required of loop loss.

Cause decay for corresponding high-speed transfer, though made many standards, but it all is at transmission medium and connector assembly, and do not limited at connector plug (Plug), but whole high speed transmission system still is an one, wherein any link generation problem, the capital influences transmission quality greatly, the main cause that why does not limit at connector plug is because connector plug involves the factor of artificial assembling, when configuration communication stamen line, human error is too big, even the standard of making, it is also undesirable to reach rate.And in order to cooperate the connector of 5e class standard, need connector plug is met following non-imposed standard as far as possible.

The line position	Near-end crosstalk (db) is 5e Lei @100MH 1. _z
The line position	Near-end crosstalk (db) is 5e Lei @100MH 1. _z	1-3	34.4-37.6
3-2	42-50	1-3	34.4-37.6
3-2	42-50	3-4	42-50
1-2	≥50	3-4	42-50
1-2	≥50	1-4	≥50
2-4	≥60	1-4	≥50

And connector plug can produce and disturbs the main cause cause transmission attenuation, still because its eight telecommunication stamen lines be parallel and be positioned at same plane earth and be disposed at connector plug, so its each line to interference value quite big, transmission quality also is on duty mutually.And at this problem, preceding case has proposed the method for some solutions, be to utilize a guide plate, with first pair and second, four pair and the 3rd pair, guide respectively and split on three planes, utilizing metallic conductor to make effect again increases compensation effect, though it can meet above-mentioned standard (actual conditions still will be subject to artificial assembly error) but still have many problems in theory:

1. still become parallel between every pair of communication stamen line, have certain interference to exist.

2. adopt multi-piece type (guide plate and a plurality of metallic conductor), so the cost height.

3. because communication stamen line divides as for three planes, so the sheet metal of its contact communication stamen line stamen heart need have three kinds of specifications, cost can increase, and can not be shared with the sheet metal of general connector plug.

4. its guide plate adopts the perforation formula, and threading is not easy (because of line-spacing is that the 1.02mm line directly is 1.0mm), so processing comparatively bothers.

The purpose of this utility model is to propose a kind of communications connectors plug of being made up of shell, sheet metal and shim.It is not only easy to assembly, and reduces human error and improve the quality of transmission greatly, thereby has solved the existing in prior technology problem.

The technical scheme that the utility model adopted is that it includes:

One shell, its front end is provided with a plurality of location notchs, and other has one to the oblique Elastic buckle that extends of the back extreme direction of this shell up;

A plurality of isometric sheet metals, it is installed in these a plurality of location notchs, is connected in order to contact with the stamen heart of the communication stamen line that is disposed at this communications connectors plug, and makes communication stamen line be distributed in same plane; And

One shim, it is installed in this shell, has a low early and high after inclined-plane, with a plurality of grooves that are distributed on this inclined-plane, be disposed at the communication stamen line of this communications connectors plug before being connected in these a plurality of sheet metals in order to guiding, make the group that forms by first and third, six and No. seven line and the group that forms by second, four, five and No. eight line, be separated in the both sides up and down of this shim, produce a kind of vertical parallax with capacity effect.

Advantage of the present utility model is:

1. adopt the shim of single type, reduce cost.

2. communication stamen line adopts open fixation, and assembling reduces artificial error of assembling easily and significantly, improves the ratio of its compliant.

3. sheet metal adopts general requirements, can be shared with general sheet metal.
