Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1, 2 and 3, a high temperature resistant and flame retardant automotive connector includes a housing 1, a first chamber 2 and a second chamber 3 are arranged in the housing 1, a printed circuit board 5 with a switch element 4 is arranged in the second chamber 3, a plurality of conductive terminals configured to be coupled to the printed circuit board 5, a signal terminal 6 for receiving a control command from the printed circuit board 5, a plurality of cable lines connected to a motor are arranged in the first chamber 2, the conductive terminals include a first terminal 7 for receiving a voltage from a power line, a second terminal 8 for receiving a reference potential from a reference potential line 15, and a third terminal 9 for receiving a voltage indicating an ignition state, the cable lines include a first cable 10 connected to the first terminal 7, a second cable 11 connected to the second terminal 8, and a third cable 12 connected to the third terminal 9, the cable lines are provided with a signal cable 13, the signal cable 13 is connected to the signal terminal 6 and the switching element 4 is connected between the second cable 11 and the second terminal 8 and is controlled by a third cable 12.
The second cable 11 and the signal cable 13 are connected to two conductors of the printed circuit board 5, respectively, inside the first chamber 2; in the second chamber 3, said first terminal 7 is connected to a first cable 10, the second terminal 8 is connected to a second cable 11 and the third terminal 9 is connected to a third cable 12.
The printed circuit board 5 further comprises an electrical protection circuit 14 connected between the third terminal 9 and the control terminal of the switching element 4.
When the connector is specifically implemented, the connector is used for the connector of the motor of the automobile, and can protect the motor before overcurrent or short circuit occurs, so that the motor system is restarted to run under the condition of not replacing any part of the motor; when the vehicle is in a sleep and rest mode, the disconnection and safety state of a motor system are ensured; the first chamber 2 and the second chamber 3 create compartments to keep the components subject to possible high power short circuits isolated from the components subject to possible low power short circuits.
The working principle of the utility model is as follows: the motor M has two power supply terminals configured to be connected to a power supply line and a reference potential line 15 so as to supply power to a battery of the vehicle, and the motor M further includes a signal terminal 6, the signal terminal 6 being configured to receive a control command from a signal line of the printed circuit board 5 to control the start, stop or rotation speed of the motor M.
A first terminal of the switching element 4 is intended to be connected to a reference potential line 15, a second terminal of the switching element 4 is intended to be connected to a respective supply terminal, and a control terminal, of the motor M. The switching element 4 is configured to connect a key line carrying a voltage indicative of the ignition status of the vehicle, the ignition switch being connected between the key line and a voltage source which may be + 12V. Therefore, when the ignition switch is turned on, the key wire carries a high voltage. When the ignition switch is turned off, the key wire is supplied with a low voltage. The ignition switch is turned on or off depending on the ignition state of the vehicle, or typically the location or presence of the vehicle ignition key, or more generally, the ignition switch is turned on when the vehicle is turned on, and the ignition switch is turned off when the vehicle is turned off or in a sleep rest mode;
the switching element 4 is configured to allow or prevent power supply to the motor M according to the voltage of the key wire. When the voltage of the key wire is low, the switching element 4 blocks the power supply to the motor M. For example, when the voltage of the key line is zero, the switching element 4 disconnects the reference potential line 15 from the corresponding power supply terminal of the motor M; in this way, it is ensured that the motor M is in a safe power-off state when the ignition switch is turned off. Since the motor is de-energized, a short circuit does not occur in the motor M.
The shell in the embodiment of the utility model can be made of a composite material with Chinese patent publication No. CN 110922787A; the composite material is compounded by polystyrene carbonized microspheres and polyetherimide. Has better high temperature resistance, mechanical property and flame retardant property.
