The present invention relates to electrical connectors, and more particularly, to an electrical connector having an electromagnetic interference shield.
In the prior art, in order to improve the performance of an electrical connector, it is often necessary to provide a metal shielding shell for blocking undesired electromagnetic interference. The shielding shell is typically sheathed on the insulation body, and the terminals of the connector are inserted in the insulation body and surrounded by shell for shielding the signal terminal of the connector from external electromagnetic interference. However, for a connector with both power and signal terminals, the power terminal may still generate interference which affects the signal terminal. This can reduce signal transmission quality to below desired and/or required levels.
Accordingly, improved solutions for reducing electromagnetic interference are desired.
According to an embodiment of the present disclosure, a connector includes a metal shell, and an insulation body received in the metal shell and formed with a slot. First and second terminal openings are provided in the insulation body and are separated by a metal sheet inserted into the slot of the insulation body.
The invention will now be described by way of example with reference to the accompanying Figures, of which:
Exemplary embodiments of the present disclosure will be described hereinafter in detail with reference to the attached drawings, wherein the like reference numerals refer to the like elements. The present disclosure may, however, be embodied in many different forms and should not be construed as being limited to the embodiment set forth herein; rather, these embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the concept of the disclosure to those skilled in the art.
In the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the disclosed embodiments. It will be apparent, however, that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and devices are schematically shown in order to simplify the drawing.
According to embodiments of the present disclosure, a connector includes a metal shell having an insulation body received therein. The insulation body includes a signal terminal and a power terminal arranged therein, and defines a slot for receiving a metal sheet for separating the signal terminal from the power terminal. The metal sheet includes elastic contact features formed on both sides thereof for elastically and electrically contacting an inner wall of the metal shell when inserted within the slot of the insulation body.
As shown in
When the metal sheet 140 is inserted into the slot 111 of the insulation body 110, the elastic contact features on both sides of the metal sheet 140 are respectively in elastic electrical contact with the inner wall of the metal shell 130. In this way, the inner space of the metal housing 130 can be separated into two electromagnetic shielding spaces with closed magnetic circuits, thus effectively preventing the signal terminal 121 from being interfered by the power terminal 122.
As shown in
As shown in
As shown in
In an embodiment, the middle region 141a of the outer end 141a, 141b is used as an electrical contact area for electrical contact with the mating metal sheet of the mating connector. The side regions 141b of the outer end 141a, 141b are used as an operation part for inserting the metal sheet 140. Therefore, the metal sheet 140 may be inserted into the insulation body 110 by pushing the side regions 141.
In an embodiment, a guide groove 130b matched with a side edge of the metal sheet 140 is formed on the inner wall of the metal shell 130 to guide the metal sheet 140 to be inserted into the slot 111 of the insulation body 110. As shown in
In the exemplary embodiment, the slot 111 in the insulation body 110 is located in a plane passing through the central axis of the insulation body 110. Two rib protrusions 130a are formed on the inner wall of the metal shell 130. The two rib protrusions 130a extend along a direction parallel to an axis of the metal shell 130 and are opposite to each other in a radial direction of the metal shell 130. Two positioning grooves corresponding to the two rib protrusions 130a are formed on the outer wall of the insulation body 110. The two rib protrusions 130a are respectively positioned in the two positioning grooves.
In an embodiment, the connector 100 is a plug connector, and the connector 100 further comprises a metal outer sleeve 150 sheathed on the metal shell 130. A threaded part 151 suitable for threaded connection with the mating connector is formed on the metal outer sleeve 150.
It should be appreciated for those skilled in this art that the above embodiments are intended to be illustrated, and not restrictive. For example, many modifications may be made to the above embodiments by those skilled in this art, and various features described in different embodiments may be freely combined with each other without conflicting in configuration or principle.
Although several exemplary embodiments have been shown and described, it would be appreciated by those skilled in the art that various changes or modifications may be made in these embodiments without departing from the principles and spirit of the disclosure, the scope of which is defined in the claims and their equivalents.
As used herein, an element recited in the singular and proceeded with the word “a” or “an” should be understood as not excluding plural of said elements or steps, unless such exclusion is explicitly stated. Furthermore, references to “one embodiment” of the present disclosure are not intended to be interpreted as excluding the existence of additional embodiments that also incorporate the recited features. Moreover, unless explicitly stated to the contrary, embodiments “comprising” or “having” an element or a plurality of elements having a particular property may include additional such elements not having that property.
