Description

Technical Field

[0001] The present disclosure relates to a connector housing assembly for an electronic lock and a socket assembly of an electronic lock, in particular to a connector housing assembly and a socket assembly for charging an electric vehicle in the technical field of new energy vehicle charging equipment, for example. Background Art

[0002] Conventional fuel vehicles emit a large amount of pollutants, so the problem of air pollution caused by fuel vehicles is prominent. To protect the environment and reduce air pollution, the automotive industry is currently committed to developing new energy vehicles, mainly electric vehicles, because electric vehicles directly use electric energy and do not emit any pollutants. To facilitate charging of electric vehicles, currently, a charging socket for mating with a charging gun is provided on an electric vehicle to charge an in-vehicle battery; and correspondingly, an electric vehicle is generally charged through a charging pile equipped with a charging plug (or called a charging gun). During charging, the charging plug is directly inserted into the charging socket on the electric vehicle to charge the electric vehicle.

[0003] For example, according to national standard requirements, when charging an electric vehicle, to prevent the charging gun from being accidentally separated from the charging socket during charging to ensure safety during charging, during the charging process, the charging plug must be reliably locked to the charging socket of the electric vehicle and cannot be unplugged from the charging socket of the electric vehicle. Specifically, for example, in the prior art, an electronic lock is generally installed on the charging plug, and a pin through-hole is provided on one side of its housing for a locking pin to pass through and engage with the charging gun inserted into the charging socket to prevent the charging gun from being unexpectedly pulled out of the charging socket. And, on the opposite side of the housing, there is an electronic lock wire outlet hole, which has a plurality of wire through-holes for guiding electric wires through (the wires are used for electrical connection, for example), and a plurality of seals tightly abuting against the hole walls of the plurality of wire through-holes are sleeved on the wires accommodated in the plurality of wire through-holes as waterproof plugs.

[0004] In the electronic lock of the prior art, the waterproof plugs of the electronic lock wire outlet holes are prone to come off under abnormal operations (such as shaking a single wire greatly), especially when the wire is first inserted and then pulled, it is easy to bring the waterproof plug out of the housing, resulting in the failure of the waterproof function.

[0005] Thus, there is an urgent need in the art for an improved connector housing assembly for an electronic lock and a socket assembly of the electronic lock including the connector housing assembly, which can specifically, for example, by adding additional structures to the housing at the installation position of the waterproof plug in the electronic lock, be able to block the waterproof plug from coming out through a removable fit (e.g., a plug-in fit), so as to meet the waterproof sealing requirement of keeping the interior dry for the normal operation of the circuit provided in the interior lock, thereby aiming to achieve an optimized structural solution. At the same time, in such a structure, only a minimal modification to the structure is expected, thereby reducing the complexity and cost of structural design and manufacturing. And since there are no new parts and the assembly sequence remains unchanged, only a local modification of the structure, the assembly is thus optimized. Summary of the Invention

[0033] Figure 1 Schematic perspective view of a connector housing assembly 1 according to some embodiments of the present disclosure.

[0034] According to an overall technical concept of the present disclosure, for example, as shown in Figure 1As shown, a connector housing assembly 1 for an electronic lock suitable for use in the field of electric vehicle charging (e.g., in a charging socket) is provided, comprising a housing 10, wherein the housing 10 is provided with, for example, a plurality of wire through holes 101 at one end along its longitudinal direction Y, which are configured to guide a plurality of wires 20 to pass through respectively, and the plurality of wire through holes 101 are configured to respectively accommodate a plurality of wires 20 and a plurality of seals 30 sleeved on the plurality of wires 20, and, for example, a waterproof sealing ring is additionally provided between the wires and the wire through holes. In an exemplary embodiment, for example, each wire through hole 101 is configured to accommodate a corresponding wire 20 and a corresponding seal 30 sleeved on the corresponding wire 20 and abutting against the corresponding hole wall and the corresponding wire 20 with its corresponding hole wall. As an example, the plurality of seals 30 are, for example, a plurality of waterproof plugs sleeved on the circumference of the wire 20. A retaining device is provided at the free end of the hole wall of the multiple wire through holes 101, for example along the longitudinal direction Y, and the retaining device is configured to retain a stopper, which at least partially blocks the corresponding seal 30 in the corresponding hole wall of each wire through hole 101 when held in place by the retaining device.

[0035] Through this arrangement, it is achieved that in, for example, a charging socket, an additional stop structure added to the outside of the shell 10 can be used to at least partially block the corresponding sealing member 30, such as a waterproof plug, in the corresponding hole wall of each wire through hole 101 through its removable cooperation, that is, the waterproof plug is prevented from accidentally falling out of the wire through hole 101 by limiting its position, so as to meet the waterproof sealing requirement of keeping the interior dry for the normal operation of the circuit set in the internal lock, thereby aiming to achieve an optimized structural solution.

[0036] And by way of example, typically, the retaining device is configured to retain a stop, specifically ie, for example, to receive (in this context means to accept other components inserted therein) or to fix.

[0037] According to an exemplary embodiment of the present disclosure, as shown in the figure, the stopper is held in place by the retaining device, and the contour of the stopper limits the end face of the corresponding seal 30 accommodated in the corresponding hole wall of each wire through hole 101 facing the outside of the shell 10, so as to prevent the corresponding seal 30 from escaping outward from the wire through hole 101, for example, along the longitudinal direction Y.

[0038] In a further embodiment, as shown in the figure, the contour of the stopper limits the end surface of the corresponding sealing member 30 facing the outside of the housing 10 inwardly relative to at least a portion of the circumference of each wire through hole 101.

[0039] Thus, through such an arrangement of the stopper relative to the holding device, by adapting the stopper to the holding device, the end faces of a plurality of seals 30 are limited, thereby effectively preventing the corresponding seals 30 from, for example, protruding outward from the wire through-hole 101 along the longitudinal direction Y.

[0040] In the first exemplary specific embodiment according to the present disclosure, further, as shown in the figure for example, the housing 10 is open at one side (e.g., the top), and the connector housing assembly 1 further includes a top cover 40, and the top cover 40 is configured to be fitted to the housing 10 and cover the open side.

[0041] In a further embodiment, as shown in the figure for example, the top cover 40 has a protrusion 41 extending from its bottom surface to serve as the stopper, and the shape and size of the protrusion 41 are determined to be suitable for insertion into the holding device.

[0042] And, regarding the specific fitting manner, in the exemplary embodiment, as shown in the figure for example, the holding device includes: a first holding portion 51, including a pair of walls extending outward from the top side of the end of the housing 10 where the plurality of wire through-holes 101 are located, for example, along the longitudinal direction Y, and the free ends of the pair of walls are bent toward each other and spaced apart from each other; and a second holding portion 52, extending outward from the bottom side of the end of the housing 10 where the plurality of wire through-holes 101 are located, for example, along the longitudinal direction Y, and being a hollow cylinder having a U-shaped cross-section, and the crown of the U-shaped cross-section of the hollow cylinder faces outward.

[0043] Through such an arrangement, the protrusion 41 serving as the stopper is firmly held in place relative to the holding device specifically arranged as above, and thus, through reliable adaptation, the protrusion 41 serving as the stopper effectively limits at least a part of the end faces of the plurality of seals 30 accommodated in the plurality of wire through-holes 101 to prevent them from protruding.

[0044] And, even further, as a specific embodiment, as shown in the figure for example, the protrusion 41 is columnar and protrudes from the bottom surface, and its shape and size are determined to be suitable for insertion into both the space between the pair of walls of the first holding portion 51 and the hollow space defined by the hollow cylinder of the second holding portion 52.

[0045] And, as a specific embodiment, as shown in the figure for example, the plurality of wire through-holes 101 are arranged in at least two rows (typically two rows as shown in the figure) extending from the top side to the bottom side and being staggered from each other, and the contour of the protrusion 41 partially limits the end face portion of the corresponding seal 30 facing the outside of the housing 10 inwardly with respect to the arc side of the circumference of each row of wire through-holes 101 facing the other row of wire through-holes 101.

[0046] Figure 2 FIG. is a schematic perspective view of a connector housing assembly 1 according to other embodiments of the present disclosure.

[0047] In a second exemplary specific embodiment according to the present disclosure, further, as shown in the figure, for example, the connector housing assembly 1 further includes an outlet cover 60 to serve as the stopper, the outlet cover 60 has a plurality of outlet through holes 61 for the plurality of wires 20 to extend therethrough, and the outlet cover 60 is mounted to the holding device.

[0048] In a further embodiment, as shown in the figure, for example, the outlet cover 60 is mounted to the holding device, and the plurality of through holes of the outlet cover 60 are aligned with the plurality of wire through holes 101.

[0049] Moreover, regarding the specific mating manner, in an exemplary embodiment, as shown in the figure, for example, in a further and further embodiment, as shown in the figure, for example, the housing 10 further has a rope through hole configured to guide a rope and arranged in parallel with the plurality of wire through holes 101 at the end of the housing 10 where the plurality of wire through holes 101 are located, and the outlet cover 60 is configured to be inserted into the holding device from a first side of the plurality of wire through holes 101 facing away from the rope through hole at the end of the housing 10 where the plurality of wire through holes 101 are located.

[0050] Moreover, regarding the specific mating manner, in an exemplary embodiment, as shown in the figure, further, the outlet cover 60 further includes: a plurality of restraining portions 62, respectively extending inward along the longitudinal Y from the top side, the bottom side, and the first side facing away from the rope through hole of the plurality of wire through holes 101 at the end of the housing 10 where the plurality of wire through holes 101 are located and being a hollow cylinder with a U-shaped cross section, the crown of the U-shaped cross section of the hollow cylinder facing away from the outlet through hole; and wavy tabs 63, protruding outward along the longitudinal Y from a second side of the plurality of wire through holes 101 at the end of the housing 10 where the plurality of wire through holes 101 are located and facing the rope through hole and opposite to the first side.

[0051] Furthermore, as a specific embodiment, as shown in the figure, for example, a plurality of protruding ribs 64 are formed on the second side of the plurality of wire through holes 101 facing the rope through hole, and the shape and size of the plurality of ribs 64 are determined to be adapted to cooperate with the wavy tabs 63.

[0052] In a more specific embodiment, for example, as shown in the figure, the top side, the bottom side, and the columnar outer surface at the first side of the hole wall of the plurality of wire through holes 101 are respectively fitted into the hollow space defined by the corresponding constraint portions 62 of the plurality of constraint portions 62.

[0053] Here, as an exemplary embodiment, the columnar outer surfaces of the hole walls of the plurality of wire through holes 101 and the plurality of ribs 64 together serve as the retaining means.

[0054] Through such an arrangement, the outlet cover 60 acting as a stopper is firmly held in place relative to the retaining device specifically arranged as above, so that through reliable adaptation, the outlet cover 60 acting as a stopper can effectively limit at least part of the end faces of the multiple seals 30 accommodated in the multiple wire through holes 101 to avoid them from falling out.

[0055] Furthermore, as a specific embodiment, for example, as shown in the figure, the contour of the outlet cover 60 radially inwardly limits the peripheral edge of the end surface of the corresponding sealing member 30 in each wire through hole 101 facing the outside of the housing 10 relative to the circumference of each wire through hole 101.

[0056] In an exemplary embodiment of the present disclosure, for example, the plurality of seals 30 are respectively accommodated in the spaces defined by the hole walls of the plurality of wire through holes 101 in an interference fit manner. Thus, this installation manner of the seal 30 itself also cooperates with the above-mentioned additional stop structure to achieve effective retention of the seal 30 in the wire through hole 101.

[0057] Based on the above-mentioned configuration, a connector housing assembly 1 suitable for the field of electric vehicle charging, such as a charging socket, can achieve the following superior technical effects that are superior to the existing technical solutions in the field (such as a double micro switch set in reverse): by adding an additional structure at the housing 10 at the installation position of the waterproof plug in the electronic lock, the waterproof plug can be blocked from coming out through a removable fit (for example, a plug-in fit) to meet the waterproof sealing requirements of keeping the interior dry for the normal operation of the circuit set in the internal lock, thereby achieving an optimized structural solution. At the same time, since in this structure, only minimal modifications are expected to the structure, the complexity and cost of structural design and manufacturing are reduced. In addition, since there are no new parts, the assembly sequence remains unchanged, and only local changes are made to the structure, thereby optimizing the assembly.

[0058] Figure 3 The diagrams include Figure 1 A schematic perspective view of the socket assembly 2 of the connector housing assembly 1 is shown; Figure 4 The diagrams include Figure 2 A schematic perspective view of the socket assembly 2 of the connector housing assembly 1 is shown.

[0059] According to another aspect of the present disclosure, as Figure 3 and Figure 4 described, the present disclosure further provides a socket assembly 2 for an electronic lock, including: the connector housing assembly 1 according to the foregoing, and an electrical connection assembly including the plurality of wires 20 and a plurality of seals 30 sleeved on the plurality of wires 20, wherein the plurality of wires 20 and the plurality of seals 30 respectively pass through the plurality of wire through-holes 101, and the plurality of wires 20 are respectively surrounded by the plurality of seals 30 in the circumferential direction.

[0060] Moreover, considering that the socket assembly 2 provided by another aspect of the present disclosure includes the connector housing assembly 1 according to the foregoing, it thus also has the advantages of the connector housing assembly 1 according to the foregoing, which will not be elaborated herein.

[0061] The connector housing assembly 1 and the socket assembly 2 in the foregoing embodiments of the present disclosure can be used to charge an electric vehicle or other electric devices, and prevent the waterproof plug serving as the seal 30 from accidentally coming out of the wire through-hole 101 accommodating it. The above description is intended to be illustrative and not restrictive.
