Embodiments of the present disclosure disclose an antenna, and relate to the field of wireless communications. In the antenna, radiation parts of the antenna are disposed on at least two layers of circuit boards on a printed circuit board: a top layer circuit board and a first layer circuit board, so that lengths of the radiation parts of the antenna are reduced, and space occupied by a printed wire of the antenna on the PCB is reduced. Therefore, reducing a PCB size becomes possible, a size of a terminal using the reduced-size PCB may also be correspondingly reduced, and the terminal may be further miniaturized.

The present disclosure provides a conductive cover, a housing assembly and a terminal. The conductive cover includes a first portion, a second portion, a conductive suspended strip and a conductive connecting member. A slot is defined between the second portion and the first portion. The conductive suspended strip is located in the slot and has a length equal to a length of the slot. An insulating layer is provided between the conductive suspended strip and the first portion, and another insulating layer is provided between the conductive suspended strip and the second portion. The conductive connecting member bridges over the slot, is electrically connected with the first portion and the second portion, and is insulated from the conductive suspended strip.

An integrated wireless data system including a wireless load cell assembly and method for measuring operational data of one or more components for safety, health monitoring, and control is provided. The wireless load cell assembly can include an energy storage device and may be configured to allow for bi-directional communication with a base unit to store operational parameters in a database for use in development of predictive maintenance techniques. The axial load cell can rotate freely for simple installation without regard to rotational orientation. A power management strategy and energy harvesting system are provided to ensure long term use of the wireless load cell assembly without the need to replace the energy storage device.

A circuit board assembly includes a circuit board having a first side and a second side opposite to the first side, a light sensor arranged on the circuit board and electrically coupled to the circuit board, and a camera module. The camera module includes a connector arranged on the circuit board and electrically coupled to the circuit board. Projections of the light sensor and the connector on a plane parallel to the first side and the second side are fully or partially overlapped with each other. A related terminal is also provided.

A data storage securing device configured to receive a data storage comprises a shell, a bracket slidably installed in the shell, and a locking module. The shell defines a through hole, and a pressing member is located at the front end of the through hole. The bracket comprises a resilient piece received in the through hole and a plurality of blocks. The locking module comprises a body slidably installed in the shell and a button. The body comprises a plurality of baffles, the button is pressed to push the body, and the plurality of baffles is disengaged from the blocks. When the bracket slides along the shell, the pressing member is pressed against the resilient piece, and the resilient piece is elastically deformed to abut against the data storage, to prevent the data storage from falling off.

An insertable fixing module of an industrial cabinet rail includes a main body, a hook, a linking slider and a press key, and the rail is installed in the industrial cabinet. The hook is installed in the linking slider. With the design of a slop pushing between the linking slider and the press key, an inverted hook portion of the hook is latched into a latching hole of a frame. In the present invention, the press key is situated on the inner side of the frame to prevent from being touched accidently. During installation, the fixing module can be inserted and fixed. During removal, the press key is pushed along the extending direction of the rail, so that the hook can be withdrawn to remove the rail. The invention improves the stability of installation and the convenience of installation and removal.

A process variable transmitter for use in an industrial process includes a housing having a cavity formed therein. The housing has a barrier which divides the cavity into first and second cavities. Preferably, measurement circuitry in the first cavity is configured to measure a process variable of the industrial process. A terminal block assembly is positioned in the second cavity. The terminal block assembly forms a seal with the housing thereby forming a third cavity between the barrier and a circuit board of the terminal block assembly.

An apparatus to clamp and support a device includes a chassis, two clamping members, an elastic element, a driving pole, a cam, and a cover. The chassis includes a blocking tab. The two clamping members include a first clamping member and a second clamping member. The elastic element is located in a receiving hole. The driving pole is rotatable relative to the chassis. The cam can engage with the driving pole, and includes a first cam flange abutting to a first engaging post of the first clamping member. The cover is mounted to the chassis. The two clamping members and the cam are located between the chassis and the cover. The cam is rotated by the driving pole. The first cam flange urges the first engaging post to move the first clamping member away from the second clamping member.
