the second engagement structure further includes:
a recess formed on a top surface of the top wall or a top surface of the first boss,
the recessed portion and the base portion are adapted to engage with a protruding portion and a positioning protrusion on the second connector housing, respectively, to ensure that the first connector housing and the second connector housing, which are combined together, cannot move relative to each other in the longitudinal direction.
12. The first connector housing of claim 11, wherein:
the base part of the plug part is provided with a first blocking surface vertical to the longitudinal direction, and the first blocking surface is used for abutting against a first matching blocking surface on the positioning bulge of the second connector shell;
the concave part is provided with a second stopping surface vertical to the longitudinal direction, and the second stopping surface is used for abutting against a second matching stopping surface on the convex part of the second connector shell.
13. The first connector housing according to claim 11, wherein:
the second engaging structure includes two of the recessed portions formed on the top surface of the top wall and the top surface of the first boss, respectively, and near both lateral sides of the top wall, respectively.
14. The first connector housing according to any one of claims 1 to 13, wherein:
the first and second engagement structures are spaced apart by a predetermined distance in a longitudinal direction of the first connector housing.
15. A second connector housing, comprising:
a bottom wall;
a first mating structure formed on a bottom surface of the bottom wall and located at one longitudinal end of the second connector housing; and
a second mating structure formed on the bottom surface of the bottom wall and located at the other longitudinal end of the second connector housing,
the first and second mating structures are respectively for mating with and interengaging with first and second engagement structures on a top surface of a first connector housing to conjoin the first and second connector housings in a stacked arrangement.
16. A connector housing assembly, comprising:
the first connector housing of any one of claims 1-14; and
the second connector housing of claim 15,
the first connector housing and the second connector housing are combined and connected together in a stacked manner.
17. A first connector, comprising:
the first connector housing of any one of claims 1-14; and
a first terminal disposed in the first connector housing.
18. A second connector, comprising:
the second connector housing of claim 15; and
a second terminal disposed in the second connector housing.
19. A combination connector, comprising:
the first connector of claim 17; and
the second connector of claim 18, wherein said second connector,
the first connector housing and the second connector housing are combined together in a stacked manner.
20. A connector assembly, comprising:
the combination connector of claim 19; and
and the mating connector is mated with the combined connector.
