Description

A kind of dock plug connector

Technical field

The utility model belongs to technical field of electric connectors more particularly to a kind of dock plug connector.

Background technique

In all kinds of electronic systems of modern equipment, electrical connection device is in device and device fitting, component and component, system and is Electrical connection and signal transmitting are carried out between system, are base components necessary to constituting a holonomic system, are electrically set various In standby, the dosage of electric connector is larger, especially especially big using the dosage of electric connector aboard, an airplane in general The use of electric connector involves ten of thousands route up to hundreds of or thousands of, and therefore, electric connector is general in addition to meeting Performance requirement outside, especially important require electric connector that must reach contact good, reliable operation and easy to maintain, work It is directly connected to the normal work of aircraft electrical whether reliable, designs the safety of entire host, therefore, host circuit is to electric connector Q&r have very strict requirement, also just because of its high quality and high reliability, make it also be widely used in navigating In the military systems such as sky, space flight, national defence, the prior art exists from the point of view of using angle, since insertion force is small and separating force is big, from And the problem of leading to the reliability for influencing to contact and durability.

Utility model content

The utility model provides a kind of dock plug connector, to solve to propose the prior art in above-mentioned background technique In the presence of from the point of view of using angle, since insertion force is small and separating force is big, so as to cause the reliability and durability for influencing contact Problem.

The technical problem solved by the utility model is implemented by the following technical solutions: a kind of dock plug electrical connection Device, including shell, inner surface of outer cover connecting pipe box outer surface, the pipe sleeve inner surface connection shielding ring outer surface are described It shields ring inner surface and connects earth plate outer surface, the earth plate inner surface connects filter contact outer surface, and the filtering connects Contact element terminal interior surface connects insulator jack.

Further, the insulator jack and filter contact terminal interior surface junction apply conductive rubber.

Further, the shell inner cavity fills epoxy resin.

Further, the filter contact is pi type filter.

The utility model has the following beneficial effects:

1, this patent uses inner surface of outer cover connecting pipe box outer surface, and the pipe sleeve inner surface connects shading ring appearance Face, the shielding ring inner surface connect earth plate outer surface, and the earth plate inner surface connects filter contact outer surface, described Filter contact terminal interior surface connects insulator jack, since dock connector the place of being blocked or isolates obstructed in circuit Circuit between, erect the bridge of communication, to make current flowing, so that circuit is realized scheduled function, connector is that electronics is set Indispensable component in standby, the access along current flowing are observed, you always have found there are one or more connectors, docking For formula connector for linkage function, contact engaging and separating force is importantly mechanical performance, since contact engaging and separating force is divided into insertion force and withdrawal force (pulls out Power output is also known as separating force), the requirement of the two is different, there are peak insertion force and minimum separation power regulation in related standard, This shows that from the point of view of using angle, insertion force wants small (thus having low insertion force LIF and the structure without insertion force ZIF), and separates Li Ruotai is small, then will affect the reliability of contact, and since mechanical life is actually a kind of durability, this improves connections The reliability and durability of device.

2, this patent connects earth plate using pipe sleeve inner surface connection shielding ring outer surface, the shielding ring inner surface Outer surface, the earth plate inner surface connect filter contact outer surface, the filter contact terminal interior surface connection insulation Body jack, since filter contact is mentioned by through-hole and earth plate and cage connection to effectively filter out interference signal as far as possible Contact area between high earth plate and connector shell.

3, this patent uses flexible connection between earth plate and connector, i.e., in the earth plate excircle of fixed filters 360 degree of earth plate and electrical connector housing can be made reliably when the component is packed into shell using elastic shading ring on cylinder Electrical connection, and influence of the mechanical stress to filtering device is avoided to the maximum extent.

4, this patent simultaneously in the end face that earth plate is connected with connector shell, lead by the injection preferable epoxy of electric conductivity Electric glue prevents epoxy resin from penetrating into shielding czermak space, to ensure that the online device of filtered electrical excellent shielding properties and ground connection can By property.

Detailed description of the invention

Fig. 1 is a kind of structural schematic diagram of dock plug connector of the utility model.

Specific embodiment

The utility model is described further below in conjunction with attached drawing:

In figure: 1- shell, 2- pipe sleeve, 3- shading ring, 4- earth plate, 5- filter contact, 6- insulator jack, 7- are conductive Rubber, 8- epoxy resin.

Embodiment:

The present embodiment: as shown in Figure 1, a kind of dock plug connector, including shell 1,1 inner surface of shell connect 2 outer surfaces of adapter tube set, 2 inner surface of pipe sleeve connect 3 outer surface of shading ring, and 3 inner surface of shading ring connects outside earth plate 4 Surface, 4 inner surface of earth plate connect 5 outer surface of filter contact, 5 terminal interior surface of the filter contact connection insulation Body jack 6.

The insulator jack 6 applies conductive rubber 7 with 5 terminal interior surface junction of filter contact.

1 inner cavity of shell fills epoxy resin 8.

The filter contact 5 is pi type filter.

Working principle:

This patent connects shading ring appearance by inner surface of outer cover connecting pipe box outer surface, the pipe sleeve inner surface Face, the shielding ring inner surface connect earth plate outer surface, and the earth plate inner surface connects filter contact outer surface, described Filter contact terminal interior surface connects insulator jack, since dock connector the place of being blocked or isolates obstructed in circuit Circuit between, erect the bridge of communication, to make current flowing, so that circuit is realized scheduled function, connector is that electronics is set Indispensable component in standby, the access along current flowing are observed, you always have found there are one or more connectors, docking For formula connector for linkage function, contact engaging and separating force is importantly mechanical performance, since contact engaging and separating force is divided into insertion force and withdrawal force (pulls out Power output is also known as separating force), the requirement of the two is different, there are peak insertion force and minimum separation power regulation in related standard, This shows that from the point of view of using angle, insertion force wants small, and if separating force is too small, will affect the reliability of contact, due to machinery Service life is actually a kind of durability, and the utility model solves the prior art and exists from the point of view of using angle, due to insertion force The problem of small and separating force is big, the reliability and durability that contact so as to cause influence, the strong, contact with reliability and durability Area is big, good wave filtering effect, is grounded reliable advantageous effects.

Using the technical solution of the utility model or those skilled in the art technical solutions of the utility model inspiration Under, similar technical solution is designed, and reach above-mentioned technical effect, it is to fall into the protection scope of the utility model.
