Description

The novel connector of bullhead

The utility model is the novel connector of a kind of bullhead, especially the bullhead signal connector that a kind of antimagnetic effect is stronger, this kind connector, be to allow originally must be hidden in the structure penetralia by external signal connecting line, and utilize insulation, antimagnetic coating, make the antimagnetic ability of its connector stronger.

According to investigations, a kind of serially connected signal connector by AMP Inc.'s manufacturing (AMPLIMITE Series Busing Connectors) is arranged at present on the market, as shown in Figures 1 and 2, this kind bullhead signal connector, be the external design of a kind of signal connecting line, and this be because, its connector 1, be a kind of fishplate bar interface 13 that utilizes, and be laid on metal inserting terminal extension 131 on its interface, and make its plug port 11 and connectivity port 12 form one, this metal inserting terminal extension is to be extended to its splice port or plug port by the metal inserting terminal of plug port or splice port to be provided with, middle, and grand establish a wire clamp, this kind design, the connection of its holding wire 2, to be forced to become a kind of outside ways of connecting, therefore, this design will inevitably be after pivot joint be finished, cover on its articulated section one dustproof, antimagnetic lid 14, then, the pivot that can make with metal again closes lid 15,16 are overlayed on the outermost layer of its connector.And the signal connector of being made is understood because the mode that is connected to outside pivot joint of its holding wire in this manner, and reduce the ability of its magnetic field protection, and, unescapablely be, this connector, the user must carry out the plate face of connector repeatedly contraposition and connect when connecting holding wire, like this, connect the possibility that bit-errors produces with having, but also can lose time, therefore, not a kind of connector structure design of the best, and be necessary in addition perfect.

The defective of the connector of above-mentioned routine, mainly be because: the improper institute of the structural design of fishplate bar interface 13 and metal terminal extension 131 causes.Because, because rigid use fishplate bar interface 13, therefore, just cause between the two ends of connector, can cause an interface interval, and like this, just have the many spaces that can't cover easily, and come out in the metal terminal extension 131 on it, adding this kind metal terminal extension is to be used for attachment plug port one 1 and splice port 12, therefore, outside magnetic field just is easy to and can produces magnetic interference to the conducting metal of this kind exposure, make its signal that transmits to compare instability, even be changed, like this, connector just can't satisfy signal converting requirement (undistorted); And, the defective of this magnetic interference, do not separately exist on this fishplate bar interface that exposes, but, cause jointly with the structural design of its signal connecting line 2 is improper, as previously mentioned, when this kind fishplate bar interface is used for signal connecting line 2, having localized metallic terminal extension 132 exposes, and, its holding wire can be forced to be divided into both sides and articulate up and down, in this segment signal line length zone that articulates, this connector will become a no-man's-land (promptly referring to not have any antimagnetic design), this be because, its signal connecting line 2 contained metal separation nets 21 own coat this connector, and, why do like this, mainly be because, must avoid the metal terminal extension and the issuable magnetic field effect of separation net that expose, therefore, powerful magnetic field influences the stable of its signal with regard to being easy to penetrate, and, this effect can because the exposure portion of metal terminal extension with its by the magnetic strength difference at holding wire shield position, and make the stability of its signal can be more unstable, like this, if use the next switching of this connector, be unwise or even dangerous as signal.The trouble that the connection contraposition repeatedly of more indescribable this kind connector is caused with not.

Therefore, the purpose of this utility model promptly is to propose a kind of novel connector construction design that overcomes the conventional design defective, makes aforesaid antimagnetic effect weakness, contraposition connect the trouble of holding wire, eliminates fully or weakens.

Main purpose of the present utility model promptly is to provide a kind of novel connector construction design of bullhead with good antimagnetic ability, makes it can eliminate the interference of exterior magnetic field fully.

Secondary objective of the present utility model, be to provide a kind of connector design of avoiding the outer signal line, make holding wire after entering connector, become a kind of concealed design that is capped, simultaneously, because the structure collocation design of splice port makes its holding wire become a kind of directly pattern of circuitous widely different connection, and this kind design can replace the improper interface design of conventional interface fishplate bar.

And the formation of above-mentioned utility model can be explained by following accompanying drawing and related description;
