Abstract

The present application is directed to electrical connectors that are connected to cartridges for use in image forming devices. The electrical connectors may form a communication path between the cartridge and the image forming device. The electrical connectors may include a circuit board and a housing. The housing may be configured to guide the circuit board into engagement with a corresponding connector on the image forming device. The electrical connectors may be positioned on a body of the cartridge.

Claims (16)

1. An electrical connector for a toner cartridge to mount with a corresponding connector within an image forming device, the electrical connector comprising:

a housing with a base and first and second pairs of opposing arms that extend outward from the base;

a receptacle including a first wall formed by the base and side walls formed by the first and second pairs of opposing arms;

an opening formed within the base; and

a circuit board including a first end with electrical contacts, the circuit board sized to be inserted within the opening to position the electrical contacts within the receptacle and be spaced away from the first and second pairs of opposing arms;

the housing shaped to extend around an exterior of the corresponding connector within the image forming device with the first end of the circuit board positioned within the corresponding connector wherein a lateral movement of the housing and the circuit board is allowed inside the toner cartridge body.

2. The electrical connector of claim 1 , wherein the first pair of opposing arms is spaced apart by gaps from the second pair of opposing arms to allow individual flexing of each of the arms.

3. An electrical connector for a toner cartridge to mount with a corresponding connector within an image forming device, the electrical connector comprising:

a housing with a base and outwardly extending arms that form a receptacle, the base including an opening that leads into the receptacle; and

a circuit board including a first section and a second section, the first section sized to fit within the opening and be positioned within the receptacle, the first section spaced away from the arms of the housing and recessed inward from an end of the arms;

the housing shaped to engage with the corresponding connector within the image forming device and extend around an exterior of the corresponding connector with the first section of the circuit board positioned within the corresponding connector wherein a lateral movement of the housing and the circuit board is allowed inside the toner cartridge body.

4. The electrical connector of claim 3 , wherein each of the plurality of arms includes a flared end.

5. An electrical connector for a toner cartridge to mount with a corresponding connector within an image forming device, the electrical connector comprising:

a housing with a base and outwardly extending arms that form a receptacle, the base including an opening that leads into the receptacle; and

a circuit board removably attached to the housing and including a first section and a second section, the first section including a plurality of electrical contacts and being sized to fit within the opening to position the electrical leads within the receptacle;

the housing shaped to engage with the corresponding connector within the image forming device and extend around an exterior of the corresponding connector with the electrical contacts being positioned within the corresponding connector wherein a lateral movement of the housing and the circuit board is allowed inside the toner cartridge body.
