The camera accessory is attachable to a camera. The camera accessory includes an accessory mount to be detachably coupled with a camera mount). The accessory mount is provided with accessory bayonet claws and brought, by relative rotation with the camera mount, from a first state in which each of the accessory bayonet claws is inserted between camera bayonet claws provided in the camera mount into a second state in which the accessory bayonet claws engage with the camera bayonet claws to complete coupling of the accessory and camera mounts. The camera accessory is further provided with accessory contact surfaces arranged in a relative rotation direction of the mounts in the accessory mount. The accessory contact surfaces includes a first accessory contact surface used for indicating type of the camera accessory and is provided adjacent to the accessory bayonet claw.

The embodiment of the invention discloses a port mapping method and device and a communication system. The method comprises the following steps: obtaining static port mapping information comprising a congruent relationship among a public network port number, a DHCP (Dynamic Host Configuration Protocol) client side identification and a private network port number; obtaining the congruent relationship between the DHCP client side identification and the IP address of the private network as well as the IP (Internet Protocol) address of the public network of an NAT (Network Address Translation) gateway; and according to the congruent relationship among the obtained IP address of the public network of the NAT gateway, the DHCP client side identification and the IP address of the private address as well as the static port mapping information, building the port mapping relationship. According to the embodiment of the invention, manual configuration operation in the port mapping relationship can be carried out without waiting for the ending of the process of dynamically distributing the IP address of the private network, manual configuration workload and configuration error or repeated probability can be reduced, and manual configuration operation does not need to be carried out again after the IP address of the private network is changed.

A connector includes a male terminal housing with a plurality of first connecting terminals aligned and accommodated therein, a female terminal housing with a plurality of second connecting terminals aligned and accommodated therein, a plurality of isolating plates aligned and accommodated in the male terminal housing, a connecting member, and a lever mechanism including a lever to rotate a head of the connecting member so as to press the head of the connecting member against the adjacent one of the plurality of insulation plates. The lever mechanism further includes an operation permitting means that permits the connecting member to collectively fix the plurality of first connecting terminals and the plurality of second connecting terminals at the contacts, when the male terminal housing and the female terminal housing are in a predetermined fitting state.

The invention relates to connectors in automatic financial equipment, in particular to a connector between a cashbox and a cashbox bracket. The cashbox connector comprises a male connector positioned on the cashbox and a female connector positioned on the cashbox bracket, wherein an elastic element is arranged on the cashbox bracket, gives a driving force tightly matched with the male connector to the female connector, and is also connected with a floating plate; the elastic element gives a supporting force along the assembling direction of the cashbox to the floating plate; a protective cover device is arranged on the cashbox bracket, is positioned above the female connector, and comprises a protective cover bracket, a resetting torsional spring and a cover body; the cover body is pivoted to the protective cover bracket through a shaft; and the resetting torsional spring is sleeved on the shaft and is positioned between the cover body and the protective cover bracket to give a torque force to the cover body. Therefore, the cover body covers the female connector without external force, and the cover body is opened by a side wall of the cashbox to finish connection in the process of assembling the cashbox.
