Abstract
The utility model discloses an electrical connector plug having anti-electrostatic discharge interference. The electrical connector plug includes a connector housing and an insulation base installed on the connector housing. A plurality of contact members are installed in the insulation base. The exterior of the insulation base is sleeved by an electrostatic shield composed of an electrostatic shield body. The exterior of the electrostatic shield body is provided with an electrostatic shield step which is in mating connection with a groove in the connector housing. According to the utility model, the metallic conductor electrostatic shield is arranged outside the insulation base of the connector, the electrostatic shield step is arranged on the outer side of the electrostatic shield as a conductive region to be in electrical contact with the connector housing, and thus interference currents produced by electrostatic discharge can be effectively transferred; and since the electrostatic shield surrounds the entire insulation base, an electrostatic shielding layer is formed to prevent the electrostatic discharge interference from directly acting on the contact members.
Description
Technical field
The utility model belongs to connector technique field, specifically relates to a kind of electrical connector plug that anti-electrostatic-discharge disturbs that has.
Background technology
Electrical connector plug is as the interface components and parts of the parts such as printed circuit, control rack, unit module, the in the situation that of overall package, it is usually exposed to outside packaging body in whole or in part, in assembling, dismounting, while keeping in repair these parts, electric connector is to contact one of position the most frequently with people and miscellaneous part.In the time of human body and connector contact, because the friction of different electrified bodies produces static discharge, will cause the electric weight of moment to shift, in the time of human body and connector generation static discharge, within the time of 1ns, static discharge current can reach 100A.The electric current that moment produces forms huge electromagnetic radiation field, the momentary action of radiation field interference signal, in electric connector contact, finally acts on circuit, and interference signal is as exceeded the specified threshold values of some electronic devices and components of circuit, to cause whole circuit to damage, thereby destroy whole electronic system.
The process from plastic casing to metal shell ground connection express delivery transfer charge has been experienced in the design of conventional electric connector anti-electrostatic-discharge.In the time of human body and miscellaneous part contact-connection assembly for electric shell, the electrostatic charge producing shifts fast by the earthing of casing, thereby reduce the impact of static discharge on circuit, but, because current connector is without anti-electrostatic-discharge radiation dependency structure, and the interference signal that static discharge radiation produces is too strong, and therefore existing electric connector still can form fatal destruction to some fragile electronic devices and components.
Utility model content
For addressing the above problem, the utility model provides a kind of electrical connector plug that anti-electrostatic-discharge disturbs that has.
The utility model is achieved by following technical solution.
A kind of electrical connector plug with anti-electrostatic-discharge interference, comprise connector shell and be arranged on the insulating base on connector shell, some contacts are installed in insulating base, described insulating base outer cover is equipped with electrostatic defending cover, described electrostatic defending cover is made up of electrostatic defending cover body, be provided with electrostatic defending cover step in electrostatic defending cover body outside, electrostatic defending cover step is connected with the groove fit on connector shell.
Described electrostatic defending cover body is provided with some butt holes corresponding with contact.
Described electrostatic defending cover is metallic conductor, and wherein electrostatic defending cover step is conductive region, and connector butt hole is insulating regions.
The beneficial effects of the utility model are:
Compared with prior art, the utility model is by the insulating base outer setting metallic conductor electrostatic defending cover at connector, by at electrostatic defending cover arranged outside electrostatic defending cover step as conductive region, form and electrically contact with connector shell, can also effectively shift the disturbance current that static discharge produces; Because electrostatic defending cover surrounds whole insulating base, form electrostatic screen layer, prevent that static discharge interference from directly acting on contact.Adopt the utility model by earthing of casing fast transfer electric current, to shift the induced current that static discharge produces; Also can be by Faraday cage static discharge shield technology shielding electrostatic induction electric field.The utility model is simple in structure, is easy to manufacture, and is applicable to producing in enormous quantities.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the perspective view of electrostatic defending cover in the utility model.
In figure: 1-connector shell, 2-contact, 3-electrostatic defending cover, 4-insulating base, 31-electrostatic defending cover step, 32-electrostatic defending cover body, 33-butt hole.
Embodiment
Further describe the technical solution of the utility model below in conjunction with accompanying drawing, but described in claimed scope is not limited to.
As shown in Figure 1 and Figure 2, a kind of electrical connector plug that anti-electrostatic-discharge disturbs that has described in the utility model, comprise connector shell 1 and be arranged on the insulating base 4 on connector shell 1, some contacts 2 are installed in insulating base 4, described insulating base 4 outer cover are equipped with electrostatic defending cover 3, described electrostatic defending cover 3 is made up of electrostatic defending cover body 32, be provided with electrostatic defending cover step 31 in electrostatic defending cover body 32 outsides, electrostatic defending cover step 31 is connected with the groove 11 on connector shell 1.
Described electrostatic defending cover body 32 is provided with some butt holes 33 corresponding with contact 2.
Shown in accompanying drawing 2, described electrostatic defending cover 3 is metallic conductor, and wherein electrostatic defending cover step 31 is conductive region, passes through during fabrication conductive processing, forms and electrically contacts with connector shell 1, can also effectively shift the disturbance current that static discharge produces; Connector butt hole 33 is insulating regions, is through insulation processing in manufacture, and to meet connector electric property, and electrostatic defending cover 3 surrounds whole insulating base 4, formed electrostatic screen layer, prevents from that static discharge from disturbing to directly act on contact 2.
Adopt technique scheme, not only can, by earthing of casing fast transfer electric current, shift the induced current that static discharge produces; Also can be by Faraday cage static discharge shield technology shielding electrostatic induction electric field.
