COMPACT RELIABLE RECEPTACLE CONNECTOR

Abstract
A compact, reliable receptacle connector. The connector comprises terminals held by an assembly housing. A shell surrounds mating ends of the terminals and engages with the assembly housing. A housing is disposed outside the shell and partially encloses a rear of the shell. A board lock is also partially embedded in the housing. Such a configuration enables the connector to have a single shell and reduces the risk of relevant movements between the shell/board lock and the housing when, for example, a component is inserted into or removed from the connector. The connector can comprise a front seal disposed around a portion of the shell that extends beyond the housing, and a rear seal disposed between a top of the housing and a bottom of the shell. Such a configuration can effectively block ingress of environmental contaminants from both the front and the rear.
Description
CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to and the benefit of Chinese Patent Application Serial No. 202321988693.0, filed on Jul. 26, 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 compact, reliable receptacle connectors. A receptacle connector inside a chassis of an electronic device may be configured to receive a mating component such as a plug connector to enable the electronic device to connect with other devices. Connectors according to conventional designs may have a number of components, including multiple shells, which are prone to movements relative to each other, such as when a force is applied to insert or remove a mating component from the connector. Such a force may cause various issues such as over-insertion and therefore poor or intermittent electrical contact or may cause terminal assembly dislocation.


Techniques described herein enable more compact receptacle connectors while maintaining/improving robustness. Such techniques are illustrated herein as applied to a USB Type-C right-angle receptacle connector. According to aspects of the present disclosure, a receptacle connector may include terminals held by an assembly housing. A shell may surround mating ends of the terminals and engage with the assembly housing. A housing may be disposed outside the shell and partially enclose a rear of the shell. A board lock may be also partially embedded in the housing. Such a configuration enables the connector to have a single shell and reduce the risk of relevant movements between the shell/board lock and the housing when, for example, a mating component is inserted into or removed from the connector. The connector may comprise a front seal disposed around a portion of the shell that extends beyond the housing, and a rear seal disposed between a top of the housing and a bottom of the shell. The seals may be made from an adhesive (e.g., UV glue, silicone, epoxy glue, or underfill). An adhesive may provide flexibility in locating the seals, as the adhesive may be applied in a liquid or viscous state and cured in place. Such a configuration can block ingress of environmental contaminants from both the front and the rear.


According to aspects of the present disclosure, risk of relative movement between the housing and the shell in the mating direction is reduced, which may also improve the sealing stability of the receptacle connector. For example, when the receptacle connector has been inserted/withdrawn several times, any relative displacement between components of the receptacle connector may be so small as to be negligible or immeasurable with conventional tools. The receptacle connector may be structurally more compact and stable than conventional designs, which can block ingress of environmental contaminants more effectively and lead to a longer service life.


Some of all of the foregoing techniques may be used to provide a compact connector. In some examples, the connector may occupy less space in an electronic system than a connector made according to conventional techniques to meet a standard, such as USB-C. Instead of or in addition to techniques as described above, the connector may have a limited number of terminals, such as 6 terminals. The terminals may be positioned, for example, to mate with terminals of a plug connector compliant with USB-C standards that are used for power delivery.


Next, exemplary embodiments of the receptacle connector according to one aspect of the present application will be described in detail with reference to the accompanying drawings.


As shown in FIGS. 1-12, the receptacle connector 1 is for connecting with a corresponding plug connector in a mating direction X, to establish an electrical and/or signal connection to an external electronic device. The receptacle connector 1 may comprise a terminal assembly 10, a shell 20, a housing 30, and a first sealing member 40 attached to the shell 20. The terminal assembly 10 may comprise a plurality of conductive elements 110 and an assembly housing 120 accommodating the conductive elements. The assembly housing 120 of the terminal assembly 10 may be molded over the conductive elements 110 to form an integral component, as shown in FIG. 10 and FIG. 11. In some exemplary embodiments, the assembly housing 120 may be made of an insulative material, such as plastic or nylon. Examples of suitable materials include, but are not limited to, liquid crystal polymer (LCP), polyphenylene sulfide (PPS), high temperature nylon or polyphenylenoxide (PPO) or polypropylene (PP). Other suitable materials may be employed, as aspects of the present disclosure are not limited in this regard. The shell 20 may have a hollow, substantially cylindrical shape and may be sleeved on at least a portion of an outer side of the terminal assembly 10. The shell 20 may be made of a metallic material. The housing 30 may be provided on at least a portion of an outer side of the shell 20.


A first board lock 220 and a second board lock 230 may be provided respectively on opposite sides of the receptacle connector 1 in a width direction Y perpendicular to the mating direction X. As shown, the first board lock 220 and the second board lock 230 are respectively spaced apart from two opposite sidewalls of the shell 20 located in a width direction Y perpendicular to the mating direction X. The housing 30 is molded over at least a portion of the outer side of the shell 20, and forms an integral component with the shell 20. As shown in FIG. 1, the first board lock 220 and the second board lock 230 are at least partially embedded in the housing 30 and extend beyond the housing 30 in a thickness direction Z perpendicular to the mating direction X of the receptacle connector 1, for example, exposed from the housing 30.


When the receptacle connector according to an exemplary embodiment of the present application is mated with a corresponding plug connector, a relative movement between the shell 20 and the housing 30 along the mating direction X is prevented, since the first board lock and the second board lock of the shell 20 are at least partially embedded in the housing 30 and extend at least partially beyond the housing 30. Relative movement between the various components provided in the receptacle connector 1 will also be prevented. For example, relative movement between the first sealing member 40 provided on the shell 20 and the shell 20 and with the housing 30 will be prevented so that gaps will not appear between the various components of the receptacle connector. For example, even if the receptacle connector has been inserted/withdrawn several times, there is no relative displacements between various components of the receptacle connector, for example, a delaminated phenomenon or a phenomenon where the sealing member falls off will not occur, such that the receptacle connector is structurally more compact and stable, which significantly improves the waterproof performance of the receptacle connector.


The first board lock 220 is provided with a cantilever portion 221 substantially extending along the mating direction X and a plurality of mounting portions extending from the cantilever portion 221 along the thickness direction Z. As shown in FIGS. 6-8, the first board lock 220 is provided with a first mounting portion 222 and a second mounting portion 223 spaced apart from each other. At least a portion of each of the first mounting portion 222 and the second mounting portion 223 as well as the cantilever portion 221 are embedded in the housing 30, and a distal end of the first mounting portion 222 and a distal end of the second mounting portion 223 extend beyond the housing 30.


According to an exemplary embodiment of the present application, a snap engagement portion may be provided on the distal end of the first mounting portion 222 and the distal end of the second mounting portion 223, respectively. In the case where the receptacle connector 1 is connected to a component to be applied, such as a printed circuit board, the snap engagement portions of the first mounting portion 222 and the second mounting portion 223 are mated with a corresponding engagement portion of the printed circuit board in the thickness direction Z. Optionally, the distal end of the first mounting portion 222 and the distal end of the second mounting portion 223 may also be connected to the component to be applied by soldering. It should be understood that the first mounting portion and the second mounting portion may also be connected to the component to be applied by any other suitable connections.


As shown in in FIGS. 6-8, the first board lock 220 and the second board lock 230 are mirrored about a plane passing through a vertical central axis of the shell 20 along the thickness direction Z. This symmetrical provision may allow a more uniform force to be applied to the receptacle connector 1 when the receptacle connector 1 is withdrawn and inserted, thus enabling a more structurally stable receptacle connector.


As shown in FIGS. 6-8, the shell 20 comprises a first sidewall 211 and a second sidewall 212 opposite in the width direction Y and a third sidewall 213 and a fourth sidewall 214 opposite in the thickness direction Z, according to an exemplary embodiment of the present application. The shell 20 may also include a first connecting portion 224 and a second connecting portion 234, as illustrated in FIG. 6. The first connecting portion 224 is provided between a rear end of the first board lock 220 and a rear end of the first sidewall 211 and connects the first board lock 220 with the first sidewall 211. The second connecting portion 234 is provided between a rear end of the second board lock 230 and a rear end of the second sidewall 212 and connects the second board lock 230 with the second sidewall 212. The shell 20 is formed integrally with the first board lock 220 and the second board lock 230. For example, the shell 20 and the first and second board locks 220, 230 may be formed integrally by stamping a sheet of metal and wrapping, folding, and/or bending the stamped sheet.


In some embodiments, the first board lock 220, the second board lock 230, the first connecting portion 224, and the second connecting portion 234 may be made of the same material as the shell, e.g., a metallic material.


In some embodiments, each of the first connecting portion 224 and the second connecting portion 234 is formed to have a U-shaped shape. It should be understood that the first connecting portion 224 and the second connecting portion 234 may be formed to have any other suitable shape, such as a rectilinear shape or a semi-circular shape.


According to another exemplary embodiment of the present application, the first board lock 220 and the second board lock 230 of the shell 20 may be separately formed members independent of the sidewalls of the shell 20, as shown in FIG. 9.


As shown in FIG. 6, one or more stop portions may be provided near the rear end of the shell 20, the stop portions protruding toward the inner side of the shell 20. The stop portions are formed integrally with the shell 20. For example, the stop portions are part of the shell 20, and no additional attachment components for attaching the shell 20 to the terminal assembly 10 are required, which reduces the number of components of the receptacle connector, and simplifies 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.


As shown in FIG. 8, the shell 20 may be provided with three stop portions, wherein the first stop portion 240 is provided on the third sidewall 213 of the shell 20, and the second stop portion 250 and the third stop portion 260 are provided on the fourth sidewall 214 of the shell 20 and spaced apart from each other. The first stop portion 240 may be formed with a concave portion recessed inward relative to an outer surface of the third sidewall 213, and the second stop portion 250 and the third stop portion 260 may be formed with a concave portion recessed inward relative to an outer surface of the fourth sidewall 214.


As shown in FIG. 10 and FIG. 11, the assembly housing 120 of the terminal assembly 10 may be provided with a first receiving portion 121 in cooperation with the first stop portion 240, a second receiving portion 122 in cooperation with the second stop portion 250, and a third receiving portion 123 in cooperation with the third stop portion 260. The first receiving portion 121 is provided on one side of the assembly housing 120 in the thickness direction Z, and the second receiving portion 122 and the third receiving portion 123 are provided on the other side of the assembly housing 120 in the thickness direction Z.


In some exemplary embodiments, the first stop portion 240, the second stop portion 250 and the third stop portion 260 may be respectively engaged with the first receiving portion 121, the second receiving portion 122, and the third receiving portion 123 in a snap-fit manner or an interference-fit manner.


As shown in FIG. 1, in the mating direction X, the mating end of the shell 20 extends beyond the mating end of the housing. The first sealing member 40 is provided along a circumferential direction of the shell 20 on an outer sidewall of the shell 20 extending beyond the mating end of the housing 30. The first sealing member 40 seals the engagement portion between the shell 20 and the housing 30 in a circumferential direction. In addition, when the receptacle connector is connected with a mounting portion of a corresponding electronic device, the first sealing member 40 further forms a seal between the shell and the mounting portion of the electronic device, effectively preventing water or dust entering from the socket of the USB Type-C receptacle connector from entering the interior of the electronic device, avoiding a short circuit inside the electronic device, and improving safety performance.


In some exemplary embodiments, as shown in FIGS. 6-9, a rough portion 270 is provided on an outer sidewall of the mating end of the shell 20 extending beyond the mating end of the housing 30. The first sealing member 40 is attached to the rough portion 270 of the shell 20, and the rough portion 270 comprises a pattern formed by at least one of a diagonal pattern, a grid pattern, or a predetermined symbol pattern.


According to an exemplary embodiment of the present application, the first sealing member 40 is attached to the rough portion 270. The rough portion 270 has a coefficient of friction greater than other portions of the outer sidewall of the shell. Therefore, by the provision of the rough portion, an adhesion force between the first sealing member and the rough portion of the shell is significantly improved, which allows a much tighter attachment between the first sealing member 40 and the shell 20, and effectively avoids the phenomenon where the first scaling member 40 shifts relative to the shell thus generating a gap or even falling off. Therefore, a seal can be generated between the receptacle connector and the mounting portion of the electronic device when mounting the receptacle connector 1 to the mounting portion of the electronic device to effectively prevent water vapor/dust from entering inside the electronic device.


In some exemplary embodiments according to the present application, a surface roughness of the rough portion 270 of the shell 20 may be in the range of EDM 8-12.


In some exemplary embodiments, the rough portion 270 is provided within a width range of 0.5 mm to 1.5 mm from the proximal edge of the shell 20 in the mating direction X on the outer sidewall of the shell 30.

For example, when separating items in a list, “or” or “and/or” shall be interpreted as being inclusive, i.e., 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, i.e., 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.
