15. The connector of claim 10, wherein:
the housing (1) also has a mounting end (12), the terminals (8) being inserted into the housing (1) via a mounting port (102) of the mounting end (12);
the axis of the mounting port (102) of the housing (1) is perpendicular to the axis of the port (101) of the mating end (11) of the housing (1).
16. The connector of claim 15, wherein:
the terminal (8) includes:
a terminal body (81) formed with a notch (81 a) for engagement with an end of the terminal lock (3);
a contact spring piece (82) provided in the terminal body (81) for electrically contacting a mating terminal inserted through a port (101) of the mating end (11); and
a locking spring (83) mounted on the terminal body (81) for locking the terminal (8) in the housing (1).
17. The connector of claim 16, further comprising:
a cable (6) having a conductor core (61) electrically connected to the terminal body (81); and
an end cover (5) sleeved on the mounting end (12) of the shell (1) and provided with a cable through hole,
the cable (6) protrudes into the housing (1) via a cable passage opening in the end cap (5).
18. The connector of claim 17, further comprising:
a second sealing ring (7) sleeved on the cable (6) and inserted into the mounting port (102) of the shell (1),
the second sealing ring (7) is pressed between the inner wall of the mounting port (102) of the housing (1) and the cable (6) to achieve a seal therebetween.
19. The connector of claim 18, wherein:
the end cap (5) comprises:
an inner peripheral wall part (53) inserted into a mounting port (102) of the housing (1);
an outer peripheral wall part (51) surrounding the inner peripheral wall part (53) and fitted over the mounting end (12) of the housing (1); and
an end wall portion (52) connected to one end of the inner peripheral wall portion (53) and the outer peripheral wall portion (51),
a catch (54) is formed on the peripheral wall portion (51), a boss (12 a) is formed on the mounting end (12) of the housing (1), and the boss (12 a) is engaged with a catch groove (54 a) on the catch (54) to fix the end cover (5) to the mounting end (12) of the housing (1).
20. The connector of claim 19, wherein:
the second seal ring (7) comprises:
a sealing body (70) which is sleeved on the cable (6); and
and a seal connection portion (71) which is injection-molded into the inner peripheral wall portion (53) of the end cap (5) so as to be integrated with the end cap (5).
