Receptacle housing and receptacle
The present disclosure discloses a receptacle housing and a receptacle. The receptacle housing comprises a housing body and a hole wall. The hole wall continuously extends from the housing body along an axial direction of the housing body. The hole wall surrounds along a circumferential direction of the housing body to form a mounting hole for accommodating a corresponding connecting terminal. The hole wall is provided with a water draining through-hole. By providing the water draining through-hole in the hole wall, the receptacle housing according to the present disclosure may drain water accumulated in the mounting hole in such a circumstance as water drops are brought therein upon plugging a mating connecting terminal, and provide water draining channels by means of such an ingenious structural design that safety performance may be enhanced.
1. A receptacle housing comprising:
a housing body;
a hole wall that continuously extends from the housing body along an axial direction of the housing body and surrounds along a circumferential direction of the housing body to form a mounting hole for accommodating a corresponding connecting terminal, the mounting hole is arranged to extend in a horizontal direction when the receptacle housing is in its working position; and
a water draining through-hole extending axially and radially through the hole wall to communicate the mounting hole with an outside environment;
wherein the water draining through-hole is arranged to extend continuously along the axial direction of the housing body to a free end of the hole wall;
wherein an axial length of the water draining through-hole is larger than a circumferential width of the water draining through-hole.
2. The receptacle housing according to claim 1 , wherein
when the receptacle housing is in its working position, the water draining through-hole is disposed at a bottom end of the hole wall.
3. The receptacle housing according to claim 1 , wherein
the housing body has a support face;
the hole wall is arranged on the support face; and
the water draining through-hole is arranged to be spaced apart from the support face.
4. The receptacle housing according to claim 1 , comprising a plurality of the hole walls,
wherein a fencing wall is provided on the housing body; and
the fencing wall is arranged to protrude along the axial direction of the housing body and extend along the circumferential direction of the housing body to surround all of the hole walls, forming a retaining cavity.
5. The receptacle housing according to claim 1 , wherein the receptacle housing is an electric vehicle charging receptacle housing.
6. A receptacle, comprising a connecting terminal and the receptacle housing according to claim 1 , wherein the connecting terminal is mounted in the mounting hole to be electrically connectable with a corresponding mating terminal.
7. The receptacle according to claim 6 , wherein one or more of the connecting terminals are provided for one or more of electrical connections below:
an electrical connection between a DC power supply anode and the corresponding mating terminal;
an electrical connection between a DC power supply cathode and the corresponding mating terminal;
an electrical connection between a grounded terminal and the corresponding mating terminal;
an electrical connection between a charging communication anode and the corresponding mating terminal;
an electrical connection between a charging communication cathode and the corresponding mating terminal;
an electrical connection between a first charging connection confirming terminal and the corresponding mating terminal;
an electrical connection between a second charging connection confirming terminal and the corresponding mating terminal;
an electrical connection between a low-voltage auxiliary power supply anode and the corresponding mating terminal; and
an electrical connection between a low-voltage auxiliary power supply cathode and the corresponding mating terminal.
8. The receptacle according to claim 6 , wherein
the connecting terminal is a female terminal having a contact wall;
the contact wall extends along a circumferential direction of the housing body to form an accommodating cavity;
the accommodating cavity is arranged for accommodating a corresponding male terminal;
the contact wall has a position vacating through-hole and/or a position vacating notch; and
the position vacating through-hole, the position vacating notch, and the water draining through-hole are arranged to be at least partially aligned with each other.
9. The receptacle housing according to claim 1 , wherein
the free end of the hole wall is provided with a backstop wall; and
the backstop wall is arranged to protrude inwardly along a radial direction of the housing body to prevent the connecting terminal from leaving the mounting hole.
10. The receptacle housing according to claim 9 , wherein the backstop wall has a continuous inner circumferential surface.
11. The receptacle housing according to claim 9 , wherein a second water draining through-hole is provided on the fencing wall and communicates with an outer portion of the housing body.
12. The receptacle housing according to claim 9 , wherein
the water draining through-hole is arranged at a bottom end in a vertical direction of the hole wall; and
the second water draining through-hole is arranged at a bottom end in a vertical direction of the fencing wall.
