RELIABLE RECEPTACLE CONNECTOR

Abstract
A reliable receptacle connector and method of manufacturing thereof. The connector includes a terminal assembly having conductive elements held by a housing. Each conductive element has a mating end held by a housing tongue, a tail end extending outside the housing, and an intermediate portion partially held by portions of the housing that have different contours. The terminal assembly can be formed by assembling terminal subassemblies on opposite sides of a shield and molding over the assembly to form the housing. An inner shell is sleeved on the housing and engages with both portions of the housing that have different contours. A main shell is sleeved on the inner shell. An outer shell is sleeved on the main shell and shaped such that a seal can be formed between the shells. Such a configuration enables distributing forces to mate/unmate the connector from the shells to the housing and therefore reduces relevant movements between the components of the connector.
Description
CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to and the benefit of Chinese Patent Application Serial No. 202322262902.X, filed on Aug. 22, 2023, the contents of which are incorporated herein by reference in their entirety.


TECHNICAL FIELD

This application relates to interconnection systems, such as those including electrical connectors, configured to interconnect electronic assemblies.


BACKGROUND

Electrical connectors are used in many electronic systems. It is generally easier and more cost effective to manufacture a system as separate electronic subassemblies, such as printed circuit boards (PCBs), which may be joined together with electrical connectors. Having separable connectors enables components of the electronic system manufactured by different manufacturers to be readily assembled. Separable connectors also enable components to be readily replaced after the system is assembled, either to replace defective components or to upgrade the system with higher performance components.


A known arrangement for joining several electronic subassemblies is to have one printed circuit board serve as a backplane. A known backplane is a PCB onto which many connectors may be mounted. Conducting traces in the backplane may be electrically connected to signal conductors in the connectors such that signals may be routed between the connectors. Other printed circuit boards, called “daughterboards,” “daughtercards,” or “midboards,” may be connected through the backplane. For example, daughtercards may also have connectors mounted thereon. The connectors mounted on a daughtercard may be plugged into the connectors mounted on the backplane. In this way, signals may be routed among daughtercards through the connectors and the backplane. The daughtercards may plug into the backplane at a right angle. The connectors used for these applications may therefore include a right angle bend and are often called “right angle connectors.”


Connectors may also be used in other configurations for interconnecting electronic assemblies. Sometimes, one or more printed circuit boards may be connected to another printed circuit board, called a “motherboard,” that is both populated with electronic components and interconnects the daughterboards. In such a configuration, the printed circuit boards connected to the motherboard may be called daughterboards. The daughterboards are often smaller than the motherboard and may sometimes be aligned parallel to the motherboard. Connectors used for this configuration are often called “stacking connectors” or “mezzanine connectors.” In other systems, the daughterboards may be perpendicular to the motherboard.


Connectors may also be used in computers in which the motherboard might have a processor and a bus configured to pass data between the processor and peripherals, such as a printer or memory device. Connectors may be mounted to the motherboard and connected to the bus. A mating interface of those connectors may be exposed through an opening in the enclosure for the computer, such that connectors, often attached to the peripheral through a cable, may be inserted into the connectors on the motherboard. With this configuration, a peripheral can be easily connected to a computer.


To enhance the availability of peripherals, the bus and the connectors used to physically connect peripherals via the bus may be standardized. In this way, there may be a large number of peripherals available from a multitude of manufacturers. All of those products, so long as they are compliant with the standard, may be used in a computer that has a bus compliant with the standard. Examples of such standards include universal serial bus (USB), which is commonly used in computers. The standards have gone through multiple revisions, adapting to the higher performance expected from computers over time. For example, portable electronic devices often include USB Type-C receptacle connectors for various purposes such as charging and/or exchanging data with another electronic device by connecting the USB receptacle connector with a USB plug connector.


Some USB connectors are water resistant. These connectors may include seals that block water from outside the computer enclosure from entering the computer enclosure through the opening left for the connector.

DETAILED DESCRIPTION

The inventors have recognized and appreciated techniques for making reliable receptacle connectors. A receptacle connector may be integrated inside a chassis of an electronic device and configured to receive a mating component such as a plug connector to enable the electronic device to connect with other devices. For example, USB Type-C connectors are used in various electronic devices such as cell phones, smart watches, tablet PCs, photographic equipment, game consoles, routers, electric pens, electronic cigarettes, portable monitoring devices, etc. The force applied to insert and/or remove mating components may lead to movements among the components of the receiving receptacle connectors, causing unreliable connections and/or inefficient shielding.


Techniques described herein enable more reliable receptacle connectors. Such techniques are illustrated herein as applied to a USB Type-C vertical receptacle connector. According to aspects of the present disclosure, a receptacle connector may include a terminal assembly having conductive elements held by a housing. Each conductive element may have a mating end held by a tongue of the housing, a tail end extending outside the housing, and an intermediate portion partially held by portions of the housing that have different contours. The terminal assembly can be formed by assembling terminal subassemblies on opposite sides of a shield and molding over the assembly to form the housing. The shield may have holes disposed in an array. Each terminal subassembly may have protrusions disposed at locations corresponding to respective holes in the array such that the terminal subassemblies can be assembled to opposite sides of the shield. The assembled terminal subassemblies and shield may be molded over to form the terminal assembly. Techniques described herein may reduce the complexity of manufacturing a terminal assembly by assembling and overmolding similar or identical terminal subassemblies.


An inner shell may be sleeved on the housing and engage with both portions of the housing that have different contours. In some embodiments, the inner shell may include a first portion substantially conforming to a first portion of the housing, a flange extending from the first portion of the inner shell, and a second portion extending from the flange and disposed on a second portion of the housing that has a smaller contour than the first portion of the housing. A main shell may be sleeved on the inner shell. An outer shell may be sleeved on the main shell and shaped such that a seal can be formed between the shells. Techniques described herein may enable distributing forces to mate/unmate the connector from the shells to the housing and therefore reduce relevant movements between the components of the connector.


Next, exemplary embodiments of the receptacle connector according to the present application will be described in detail with reference to the accompanying drawings. For a clear and concise description, a mating direction Y, a width direction X and a thickness direction Z may be labeled in the figure. The mating direction Y, the width direction X and the thickness direction Z may be perpendicular to one another. The mating direction Y may refer to a direction in which the receptacle connector is to connect with a corresponding plug connector. The width direction X may refer to a width direction of the receptacle connector. The thickness direction Z may refer to a height direction of the receptacle connector.


Referring to FIGS. 1-2, these figures illustrate a receptacle connector 1 according to an exemplary embodiment of the present application. Optionally, a receptacle connector according to the present application may be a USB Type-C receptacle electrical connector for an electrical device. An electronic device implements charging thereof, or data exchange with other electronic devices, by connecting a USB receptacle connector with an adaptable USB plug connector.


As shown in FIG. 1 and FIG. 2, the receptacle connector 1 may comprise: a terminal assembly 10 comprising a plurality of electrically conductive elements and an housing 11 for accommodating the electrically conductive elements, the housing 11 molded over the electrically conductive elements; an inner shell 20 sleeved on at least a portion of an outer side of the housing 11; a main shell 30 attached to an outer side of the inner shell 20 and the terminal assembly 10; an outer shell 40 attached to an outer side of the main shell 30, a mating end of the main shell 30 extending beyond a mating end of the outer shell 40 in a mating direction Y in which the receptacle connector is connected with a corresponding plug connector; and a sealing member 50 attached to the portion of an outer sidewall of the main shell 30 extending beyond the mating end of the outer shell 40. The housing 11 may comprise a first connecting portion 110 connected to the inner shell 20, the first connecting portion 110 is provided adjacent to a rear end of the main shell 30 and comprises a first engaging portion. The inner shell 20 may comprise a second engaging portion configured to engage with the first engaging portion. The second engaging portion may be formed integrally with the inner shell 20.


With the receptacle connector according to an exemplary embodiment of the present application, the second engaging portion of the inner shell 20 is engaged with the first engaging portion provided on the first connecting portion 110 of the housing 11 of the terminal assembly 10 so that the inner shell is fixed with respect to the housing of the terminal assembly, thereby effectively reduce the risk of the inner shell shifting with respect to the terminal assembly along the mating direction Y. With this configuration, a force transfer path from the inner shell 20 toward the housing is provided, thereby reducing the force transferred from the mating portion of the plug connector to the soldering pin of the outer shell of the receptacle connector through the inner shell 20 of the receptacle connector, when a user plugs or unplug the mating plug connector. For example, when a user plugs the mating portion of the plug connector to the receptacle connector by a large force, the force transferred to the soldering pin of the outer shell of the receptacle connector can be effectively reduced, thus reducing the risk of accidental separation of the soldering pin of the outer shell of the receptacle connector from the printed circuit board under the action of a large mating force.


The inner shell according to the present application comprises an engaging portion formed integrally with the inner shell, for example, the engaging portion is part of the inner shell, such that the inner shell may be attached to the terminal assembly without additional attachment components. Such a configuration may reduce the number of components of the receptacle connector, and simplify the manufacturing process, enabling a compact structure while also improving the durability of the receptacle connector. Thus the contact stability and the connection reliability between the plug connector and the receptacle connector are improved. The inner shell may be fixed effectively with respect to the terminal assembly. The risk of misaligning or undesirably shifting the inner shell of the receptacle connector with respect to the terminal assembly due to frequent plugging and removal of the mating portion of the plug connector may be reduced. Alternatively or additionally, a sealing member 50 may be provided to form a seal between the main shell and the mounting portion of the electronic device, blocking water or dust from entering through the socket of the USB Type-C receptacle connector to the interior of the electronic device, reducing the risk of a short circuit inside the electronic device, and improving safety performance.

Having thus described several aspects of several embodiments, it is to be appreciated that various alterations, modifications, and improvements will readily occur to those skilled in the art. Such alterations, modifications, and improvements are intended to be part of this disclosure and are intended to be within the spirit and scope of the invention. While the present teachings have been described in conjunction with various embodiments and examples, it is not intended that the present teachings be limited to such embodiments or examples. On the contrary, the present teachings encompass various alternatives, modifications, and equivalents, as will be appreciated by those of skill in the art.


As an example, although many creative aspects have been described above with reference to right angle connectors, aspects of the present disclosure are not limited to these. Any one of the creative features, whether alone or combined with one or more other creative features, can also be used for other types of electrical connectors, such as vertical connectors, etc.


Further, though some advantages of the present invention may be indicated, it should be appreciated that not every embodiment of the invention will include every described advantage. Some embodiments may not implement any features described as advantageous. Accordingly, the foregoing description and drawings are by way of example only.


Also, the technology described may be embodied as a method, of which at least one example has been provided. The acts performed as part of the method may be ordered in any suitable way. Accordingly, embodiments may be constructed in which acts are performed in an order different than illustrated, which may include performing some acts simultaneously, even though shown as sequential acts in illustrative embodiments.


All definitions, as defined and used, should be understood to control over dictionary definitions, definitions in documents incorporated by reference, and/or ordinary meanings of the defined terms.


In the description of the present disclosure, it is to be understood that orientation or positional relationships indicated by orientation words “front’, “rear”, “upper”, “lower”, “left”, “right”, “transverse direction”, “vertical direction”, “perpendicular”, “horizontal”, “top”, “bottom” and the like are shown based on the accompanying drawings, for the purposes of the case in describing the present disclosure and simplification of its descriptions. Unless stated to the contrary, these orientation words do not indicate or imply that the specified apparatus or element has to be specifically located, and structured and operated in a specific direction, and therefore, should not be understood as limitations to the present disclosure. The orientation words “inside” and “outside” refer to the inside and outside relative to the contour of each component itself.


For facilitating description, the spatial relative terms such as “on”, “above”, “on an upper surface of” and “upper” may be used here to describe a spatial position relationship between one or more components or features and other components or features shown in the accompanying drawings. It should be understood that the spatial relative terms not only include the orientations of the components shown in the accompanying drawings, but also include different orientations in use or operation.


It should be noted that the terms used herein are for describing specific embodiments, and are not intended to limit the exemplary embodiments according to the present application. As used herein, an expression of a singular form includes an expression of a plural form unless otherwise indicated. In addition, it should also be understood that when the terms “including” and/or “comprising” are used herein, it indicates the presence of features, steps, operations, parts, components and/or combinations thereof.


The indefinite articles “a” and “an,” as used in the specification and in the claims, unless clearly indicated to the contrary, should be understood to mean “at least one.”


The phrase “and/or,” as used in the specification and in the claims, should be understood to mean “either or both” of the elements so conjoined, e.g., elements that are conjunctively present in some cases and disjunctively present in other cases. Multiple elements listed with “and/or” should be construed in the same fashion, e.g., “one or more” of the elements so conjoined. Other elements may optionally be present other than the elements specifically identified by the “and/or” clause, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, a reference to “A and/or B”, when used in conjunction with open-ended language such as “comprising” can refer, in one embodiment, to A only (optionally including elements other than B); in another embodiment, to B only (optionally including elements other than A); in yet another embodiment, to both A and B (optionally including other elements); etc.


As used in the specification and in the claims, “or” should be understood to have the same meaning as “and/or” as defined above. For example, when separating items in a list, “or” or “and/or” shall be interpreted as being inclusive, e.g., the inclusion of at least one, but also including more than one, of a number or list of elements, and, optionally, additional unlisted items. Only terms clearly indicated to the contrary, such as “only one of” or “exactly one of,” or, when used in the claims, “consisting of,” will refer to the inclusion of exactly one element of a number or list of elements. In general, the term “or” as used shall only be interpreted as indicating exclusive alternatives (i.e. “one or the other but not both”) when preceded by terms of exclusivity, such as “either,” “one of,” “only one of,” or “exactly one of.” “Consisting essentially of,” when used in the claims, shall have its ordinary meaning as used in the field of patent law.


As used in the specification and in the claims, the phrase “at least one,” in reference to a list of one or more elements, should be understood to mean at least one element selected from any one or more of the elements in the list of elements, but not necessarily including at least one of each and every element specifically listed within the list of elements and not excluding any combinations of elements in the list of elements. This definition also allows that elements may optionally be present other than the elements specifically identified within the list of elements to which the phrase “at least one” refers, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, “at least one of A and B” (or, equivalently, “at least one of A or B,” or, equivalently “at least one of A and/or B”) can refer, in one embodiment, to at least one, optionally including more than one, A, with no B present (and optionally including elements other than B); in another embodiment, to at least one, optionally including more than one, B, with no A present (and optionally including elements other than A); in yet another embodiment, to at least one, optionally including more than one, A, and at least one, optionally including more than one, B (and optionally Including other elements); etc.


In the claims, as well as in the specification above, all transitional phrases such as “comprising,” “including,” “carrying,” “having,” “containing,” “involving,” “holding,” “composed of,” and the like are to be understood to be open-ended, e.g., to mean including but not limited to. For example, a process, method, system, product or device that contains a series of steps or units need not be limited to those steps or units that are clearly listed, instead, it may include other steps or units that are not clearly listed or are inherent to these processes, methods, products or devices. Only the transitional phrases “consisting of” and “consisting essentially of” shall be closed or semi-closed transitional phrases, respectively.


The claims should not be read as limited to the described order or elements unless stated to that effect. It should be understood that various changes in form and detail may be made by one of ordinary skill in the art without departing from the spirit and scope of the appended claims. All embodiments that come within the spirit and scope of the following claims and equivalents thereto are claimed.


In the claims, as well as in the specification above, use of ordinal terms such as “first,” “second,” “third,” etc. does not by itself connote any priority, precedence, or order of one element over another or the temporal order in which acts of a method are performed, but are used merely as labels to distinguish one element having a certain name from another element having a same name (but for use of the ordinal term) to distinguish the elements.
