Waterproofing is also disclosed.

A waterproof connector includes a plurality of contacts each extending in a fitting direction, a housing configured to hold the plurality of contacts and a mid-plate made of metal arranged to face the plurality of contacts, the plurality of contacts each including a contact-side waterproof shaped portion, a contact front portion, and a contact back portion, the mid-plate including a front portion, a rear portion, and a coupling portion for coupling the front portion with the rear portion such that a gap is formed therebetween and having a mid-plate-side waterproof shaped portion, a length in the fitting direction of a portion of the gap facing one part of contacts among the plurality of contacts and a length in the fitting direction of another portion of the gap facing the other part of contacts differing from each other.

A data communication cable assembly including a cable with wire and/or optical fiber communication mediums for transmitting data signals and/or power signals, and connectors for connecting to a pair of devices, respectively. Each of the connector includes a connector plug or receptacle configured to mate with a corresponding receptacle or plug of a device, wherein the connector plug or receptacle includes a set of electrical contacts configured to send and/or receive the data signals and/or power signals to and/or from the device; a metallic shell defining an enclosure and including first and second openings, wherein the connector plug or receptacle mate is configured to mate with the corresponding receptacle or plug of the device via the first opening, and wherein the cable extends from inside to outside of the enclosure via the second opening; and electrically-conductive filler material configured to reduce electromagnetic leakage via the first and second openings.

A ground-plug LED lamp holder is provided, including a socket, a ground-plug portion, and at least one tube portion insertedly connected between the socket and the ground-plug portion, wherein the socket includes a core shaft configured to insertedly connect to a lamp, a mounting opening configured to mount a lamp cover to the socket, and a drainage hole configured to discharge liquid inside the socket via the tube portion. By means of the design according to the present disclosure, the lamp holder can be stably installed outdoors for use and has a quick adjustment of installation height, a reasonable distribution of wires and a drainage function, which meets a requirement for using outdoors.

A card PC is pressed and held with a fixation guide from right and left sides and from the top, so that the card PC is securely fixed at a normal position, with reduced influence of vibration. After the card PC is placed at a normal position, a connector of an external device is moved to a connector of the card PC, so as to securely connect the card PC to the external device. This accordingly prevents disengagement of the connectors or other similar problems that would otherwise occur due to imperfect connection between the connectors.

A battery pack for electrically coupling with and securing to a portable electronic device having a device connector and one or more user interface components includes an electronics section and a latch section. The electronics section includes a battery compartment configured to hold one or more batteries and a connector mechanism configured to interconnect with and form a waterproof seal around the device connector. The latch section is pivotably coupled to the base portion and configured to pivot relative to the base portion to transition the battery pack between open and closed states. In the open state, the electronics section and the latch section form an open frame structure configured to enable installation of the portable electronic device in the battery pack. In the closed state, the electronics section and the latch section form a closed frame structure configured to secure the portable electronic device within an opening defined by the closed frame structure.
