This application claims priority to Chinese Patent Application No. 202121372344.7 filed Jun. 18, 2021, the disclosure of which is incorporated herein by reference in its entirety.
The present disclosure relates to the technical field of connectors and in particular to a metal housing and a connector.
A connector disposed at an end of a cable generally includes an electrical connection part which is composed of a plurality of conductive terminals and an electronic material and is used for docking of the cable and an object connector, an insulation body for accommodating the electrical connection part, and a metal housing for covering the outside of the insulation body. The functions of the metal housing are to provide a shielded environment for the electrical connection part and also to resist external forces such as external press and strike, so as to prevent the electrical connection part from being damaged and failing.
Typically, a metal housing is made of a metal sheet through processes of bending, stamping, and the like so as to enable opposite ends of the metal sheet to be connected to each other and fixed by U-shaped or dovetail-shaped riveting structures. Then, the metal sheet is formed into a cylindrical housing. Because a top wall and a bottom wall of an existing metal housing are both of flat structures, when the top wall and the bottom wall of the metal housing are subjected to large strike forces, the above-mentioned fixing structures are easily struck and easily fail, and meanwhile, the top wall and the bottom wall of the metal housing are deformed, which causes the damage and failure of the electrical connection part in the insulation body.
Therefore, it is necessary to provide a new metal housing and a new connector to solve the above-mentioned technical problem.
One aspect of the present disclosure is to provide a metal housing which is not easily deformed when being pressed and struck by external forces.
To achieve this objective, the present disclosure adopts solutions described below.
A metal housing which is configured to accommodate an insulation body includes: a first half housing on which a first overlapping portion is disposed and a second half housing on which a second overlapping portion is disposed. The first overlapping portion is overlapped with and connected to the second overlapping portion when the metal housing accommodates the insulation body.
In an embodiment, the first overlapping portion includes a plurality of cantilevers, and the plurality of cantilevers are configured to be affixed on an inner wall or an outer wall of the second overlapping portion.
In an embodiment, the plurality of cantilevers are disposed at two ends on a docking side of the first half housing.
In an embodiment, the second overlapping portion includes a plurality of docking sheets, the plurality of docking sheets are in one-to-one correspondence with the plurality of cantilevers, and a rib is disposed between every two adjacent docking sheets.
In an embodiment, an end of the rib is flush with an end of each of the plurality of docking sheets in a direction facing away from the second half housing.
In an embodiment, each of the plurality of cantilevers is configured to be affixed on an outer wall of a respective one of the plurality of docking sheets, the rib is convexly disposed relative to the second half housing, and when the each of the plurality of cantilevers is overlapped with and connected to the respective one of the plurality of docking sheets, an outer wall of the each of the plurality of cantilevers is flush with an outer wall of the rib.
In an embodiment, one of the first overlapping portion or the second overlapping portion is provided with a hook, another of the first overlapping portion or the second overlapping portion is provided with an engaging hole, and the hook is hooked in the engaging hole when the first overlapping portion is overlapped with the second overlapping portion.
In an embodiment, the first half housing or the second half housing is further provided with a riveting claw.
Another aspect of the present disclosure is to provide a connector which has better capabilities of anti-press and anti-strike.
To achieve this objective, the present disclosure adopts solutions described below.
A connector includes an electrical connection part and an insulation body which accommodates the electrical connection part, and further includes the above-mentioned metal housing which accommodates the insulation body.
In an embodiment, one radial side of the insulation body is affixed to an inner wall of the first half housing, and another radial side of the insulation body is affixed to an inner wall of the second half housing.
The present disclosure has the beneficial effects described below.
The present disclosure provides the metal housing which is formed by docking and overlapping of the first half housing and the second half housing. That is, when the first half housing and the second half housing dock and cooperate with each other to accommodate the insulation body, the first overlapping portion and the second overlapping portion respectively disposed on the first half housing and the second half housing overlap and are connected to each other to increase the anti-press capability of the metal housing so that when the metal housing is pressed and struck by the external forces, the metal housing can be less or not deformed to effectively protect the electrical connection part in the insulation body.
The present disclosure provides the connector provided with the above-mentioned metal housing, which enables the connector to have better capabilities of anti-press and anti-strike and ensures that the connector can serve in an electrical connection usage scenario effectively for a long time.

With continued reference to
It is to be noted that, in this embodiment, a Universal Serial Bus (USB) type-c connector illustrated is used as an example. The first half housing 1 and the second half housing 2 have half-housing structures with U-like cross-sections, that is, the first half housing 1 and the second half housing 2 each have a middle curved portion and flat portions located on two sides of the curved portion. Generally, the structural strength of the curved portion is greater than the structural strength of the flat portion. Therefore, in this embodiment, the first overlapping portion and the second overlapping portion are disposed on the flat portion of the first half housing 1 and the flat portion of the second half housing 2, respectively, to enhance the structural strength of the metal housing 300 located on the above-mentioned flat portions.
However, in other embodiments, if the metal housing 300 mentioned above is applied to another form of connector and the connector has a structure different from the structure illustrated, a practitioner may dispose the first overlapping portion and the second overlapping portion mentioned above on a weak part of a metal housing 300 of the corresponding structure to enhance the overall structural strength of the metal housing 30) and the connector for increasing the capabilities of anti-press and anti-strike.
As shown in
In an embodiment, the plurality of cantilevers 4 are disposed at two ends on the docking side of the first half housing 1, that is, ends of the two flat portions of the first half housing 1. The plurality of docking sheets 5 are disposed at two ends on the docking side of the second half housing 2, that is, ends of the two flat portions of the second half housing 2. In this manner, the two ends on the docking side of the first half housing 1 are each affixed on the outer wall of the second overlapping portion so that the flat portions on both the front and back sides of the metal housing 300 are structurally reinforced.
In other embodiments, the cantilevers 4 may also be configured to be affixed on the inner walls of the docking sheets 5, that is, the two ends on the docking side of the first half housing 1 are each affixed on the inner wall of the second overlapping portion. This structure can also enable the flat portions on both the front and back sides of the metal housing 300 to be structurally reinforced.
In order to further enhance the structural strength of the metal housing 300, in this embodiment, the second half housing 2 is provided with a rib 6 at a position between every two adjacent docking sheets 5. The rib 6 may protrude outwardly from the two flat portions of the second half housing 2 or may be recessed inward from the two flat portions of the second half housing 2. In an embodiment, ends of the rib 6 are flush with ends of the docking sheet 5 in a direction facing away from the second half housing 2, that is, the rib 6 extends to an end face of the docking side of the second half housing 2 and the first half housing 1 so that the rib 6 has a larger size, thereby providing more anti-press and support capacities.
It is to be understood that when the metal housing 300 is pressed and struck by the external forces, the larger the area of the metal housing 300 in contact with the external object which applies the force to the metal housing 300 is, the smaller the pressure borne by the metal housing 300 is, and thus the metal housing 300 is more capable of avoiding being deformed under pressure. Therefore, in this embodiment, the cantilever 4 is configured to be affixed on the outer wall of the docking sheet 5, the rib 6 convexly disposed the second half housing 2, and the outer wall of the cantilever 4 is flush with the outer wall of the rib 6 when the cantilever 4 is overlapped with and connected to the connecting sheet 5. Thus, the cantilever 4 on the first half housing 1 and the rib 6 on the second half housing 2 can bear external pressure together so that the pressure borne by the metal housing 300 when the metal housing 300 is pressed is reduced.
As shown in
The hook 31 and the engaging hole 32 may be disposed on the cantilever 4 and the docking piece 5, respectively. Alternatively, the hook 31 and the engaging hole 32 may be disposed on the docking piece 5 and the cantilever 4, respectively. The engaging hole 32 may be a through hole or a blind hole, which is not limited.
In addition, as shown in
In this embodiment, the cantilevers 4, the hook 31, and the riveting claw 7 which are disposed on the first half housing 1 and the first half housing 1 may be integrally formed. The docking sheets 5, the ribs 6, and the engaging hole 32 which are disposed on the second half housing 2 and the second half housing 2 may also be integrally formed. In the existing art, the processing methods for die-cutting and bending a metal sheet or the like to obtain the first half housing 1 and the second half housing 2 are provided and will not be described here.
Apparently, the above embodiments of the present disclosure are merely example embodiments for clearly illustrating the present disclosure and are not intended to limit the implementations of the present disclosure.
