In actual use, the body of the male end connector 20 in the high voltage electrical connector assembly 1 is secured to the body of the associated device by a plurality of fasteners, thereby securing the entire high voltage electrical connector assembly 1 in a set position on the associated device. The electrical connector assembly 1 according to the invention is particularly suitable for connecting cables of large wire diameter, for example cables of the 95mm 2 wire diameter specification, and accordingly can be adapted for high current carrying applications, for example the electrical connector assembly 1 can carry currents up to 370A.
Fig. 2A, 2B and 2C show a perspective view, a sectional view and an exploded view, respectively, of the female terminal connector 10 in the high-voltage electrical connector assembly 1 according to the present invention. As can be seen in fig. 2A-2C, the right angle female connector 10 includes a housing 110, a terminal assembly 120, a shield assembly, a cable retention portion 140, and a position retention device 150.
The housing 110 has an open first end 111 and an open second end 112, the first end 111 opening toward the cable access direction to receive the cable 30, and the second end 112 opening toward the terminal access direction of the male connector 20 to receive the terminals 220 in the male connector 20 (as shown in fig. 3C). The cable access direction and the terminal access direction are perpendicular to each other, and accordingly, the housing 110 forms a right angle portion of 90 degrees, and a cavity having a corner is formed inside the housing 110. The terminal assembly 120 and the shield assembly are disposed in the cavity of the housing 110 with the terminal assembly 120 disposed in a corner position of the cavity to provide electrical connection and the various components of the shield assembly extending along the cavity of the housing 110 from the first end 111 to the second end 112 to provide complete shielding. The housing 110 is typically integrally formed of an electrically insulating material.
The terminal assembly 120 in the cavity of the housing 110 has a cable connection end and a terminal connection end electrically connected to the terminals of the cable 30 and the male connector 20, respectively, in mutually perpendicular directions. Specifically, as shown in fig. 4, the terminal assembly 120 includes a wire pressing terminal 121, a spring arm jack terminal 122, a terminal sheath 123, and a protective accessory 124.
The crimp terminal 121 has crimp wings 1211 for connecting the cable 30 and a carrier plate 1212 having an opening.
