Description
Technical field
The present invention relates to field of connectors, particularly relate to a kind of adapter of connector.
Background technology
Adapter be electronic engineering technical staff often in contact with a kind of parts.Its effect is the most simple: is blocked in circuit between place or isolated obstructed circuit, erects the bridge of communication, so that current flowing, make the function that circuit realiration is predetermined.Adapter is indispensable parts in electronic equipment, and the path along current flowing is observed, and you are always found to have one or more adapter.Adapter form and structure are Protean, along with differences such as application, frequency, power, applied environments, have the adapter of various multi-form.
Conventional arranging is all that a connection seat joins a union joint, wherein connects seat fixing on circuit boards, is realized the Guan Bi of whole adapter by plug union joint.Under the conditions of some special experiment or using, need by two union joints are carried out connection.Generally, being all to use to make a switching cable, the two ends of switching cable connect two and are used for and the connection seat of union joint coupling, are transferred by this cable temporarily.Although signaling transfer point can be realized by the method, but not only add transmission range at the extra connection cable increased and connection seat, also add the impedance between two adapters simultaneously, influence of fading for signal transmission is the biggest, and because the factor repeatedly connected, the distortion that signal transmits may be caused.
Accordingly, it would be desirable to design one not only can quickly be transferred, but also the transfer impedance between union joint must be reduced, reduce decay and the union joint of distortion of signal.
Summary of the invention
It is an object of the invention to provide a kind of adapter of connector, this adaptor can be rapidly completed the switching between two union joints, it is not necessary to extra is fabricated separately special switching cable.
For achieving the above object, the present invention adopts the following technical scheme that
A kind of adapter of connector, including housing and contact pin, the end face of described housing passes through and is provided with several through holes,
The aperture of described through hole end face is equal, and the diameter of through hole internal channel is more than the aperture of through hole end face,
Arranging a contact pin in each through hole described, described contact pin is tubular construction, and the diameter of contact pin is more than the diameter in through hole end face footpath but is less than the diameter of through hole internal channel.
In technique scheme, the through hole on described housing is divided into three sections, the diameter of the interlude diameter more than other two sections.
In technique scheme, the first paragraph of described through hole and the equal diameters of the 3rd section.
In technique scheme, described contact pin is divided into three sections, the diameter of the interlude diameter more than other two sections.
In technique scheme, the first paragraph of described contact pin and the equal diameters of the 3rd section.
In technique scheme, the diameter of described contact pin first paragraph and the 3rd section is less than through hole first paragraph and the diameter of the 3rd section.
In technique scheme, the first paragraph of described contact pin is arranged in the first paragraph of through hole, and the 3rd section of contact pin is arranged in the 3rd section of through hole.
In technique scheme, the wall of the first paragraph of described contact pin and the 3rd section is divided into some pieces along contact pin axis direction.
In technique scheme, between each piece of institute's contact pin wall and block, it is provided with gap so that each piece of wall expands to surrounding under the effect of stress.
Compared with prior art, the beneficial effects of the present invention is:
The simple in construction of the present invention, contact pin is in through hole, because diameter is less than through hole, making contact pin is movable in through hole, compared with traditional adapter or adaptor, is not to be fixedly installed, therefore when, during connecting, it is unreliable not return because of being used for multiple times so that connecting；
Especially because contact pin uses polylith wall to be spliced, and diameter is direct less than through hole so that contact pin unexpanded report in connection procedure is tight so that contact pin, during repeatedly connecting plug, does not return back out existing connection tired, can ensure the reliability of connection；
Inserting from two ends because using so that plug insertion pin can contact in second segment in adaptor contact pin so that two plug insertion pins directly contact, decreasing the impedance between two plugs, reduce the distortion in signals transmission and decay.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the structural representation of contact pin in the present invention；
Wherein: 1 is housing, 2 is passage, and 3 is contact pin, and 4 is contact pin first paragraph, and 5 is contact pin second segment.
Detailed description of the invention
Below in conjunction with the accompanying drawings, the present invention is described in detail.
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
As it is shown in figure 1, the present invention includes three parts, housing and the through hole being arranged in housing, and the contact pin being arranged in through hole.The present invention is provided with through hole from housing end face to another end face, in order to ensure to be fixed on reliably in through hole by contact pin, through hole is set to three sections, the diameter of the interlude diameter more than other two sections.The first paragraph of through hole and the 3rd section the most equal.
In order to coordinate fixed installation, contact pin is set to three sections as through hole, and the diameter of second segment is more than other two sections, first paragraph and the equal diameters of the 3rd section.Contact pin is arranged in through hole, the diameter of contact pin first paragraph and the 3rd section is less than through hole first paragraph and the diameter of the 3rd section, in like this contact pin first paragraph is just arranged on the through hole first paragraph of correspondence, contact pin the 3rd section is arranged in the 3rd section of through hole, and contact pin second segment is arranged in through hole second segment.The benefit so arranged is that contact pin can move up and down left and right in through hole, and does not falls out outside through hole.
As in figure 2 it is shown, the wall of the first paragraph of contact pin and the 3rd section is divided into some pieces along contact pin axis direction, between each piece, it is provided with gap, in contact pin, is set to through hole, form tubular construction.So arrange and be advantageous in that, when outside contact pin inserts in the contact pin of adaptor, because diameter is unequal, make each piece of outward expansion of contact pin of adaptor, inwardly apply extruding force simultaneously, thus report the contact pin of tight plug, and when plug insertion pin is extracted, the contact pin of adaptor recovers former state at once.
As it is shown in figure 1, because contact pin, in through hole, is not to contact with through-hole wall so that having certain spatial margin between contact pin and through hole, therefore contact pin has avoided the occurrence of connection fatigue in connection procedure, does not return back out the deformation of existing contact pin, adds the reliability of connection.When inserting contact pin from two ends, the contact pin at two ends can contact in adaptor second segment contact pin so that two terminal adapters can be directly connected to, it is to avoid signal occurs distortion and substantial amounts of decay in transmitting procedure, it is ensured that the reliability of signal transmission.
, not in order to limit the present invention, all any amendment, equivalent and improvement etc. made within the spirit and principles in the present invention, should be included within the scope of the present invention.
