Modular backshell housing
A backshell housing includes a pair of housing parts including a first housing part and a second housing part friction welded to one another. A cable passage of the first housing part is continuous with a cable passage of the second housing part. At least one of the housing parts has a welding protrusion received in a welding notch of the other of the housing parts. The housing parts are friction welded at an interface of the welding protrusion and the welding notch.
1 . A backshell housing, comprising:
a pair of housing parts including a first housing part and a second housing part friction welded to one another, each of the housing parts is formed of a thermoplastic material, a cable passage of the first housing part is continuous with a cable passage of the second housing part, the second housing part has a welding protrusion protruding axially from a front face of a flange of the second housing part, the front face of the flange is wider than the welding protrusion in a direction perpendicular to a longitudinal axis of the second housing part, the welding protrusion is received in a welding notch of the first housing part, the housing parts are friction welded at an interface of the welding protrusion and the welding notch to form a continuous section of the thermoplastic material at the interface that connects the housing parts.
2 . The backshell housing of claim 1 , further comprising an intermediate housing part arranged between the housing parts.
3 . The backshell housing of claim 2 , wherein, prior to joining by friction welding, the intermediate housing part has a welding protrusion and a welding notch on opposite ends.
4 . The backshell housing of claim 1 , wherein at least one of the housing parts forms an elbow.
5 . The backshell housing of claim 4 , wherein the elbow is bent around about 45°.
6 . The backshell housing of claim 1 , wherein, prior to joining by friction welding, a length of the welding protrusion is longer than a depth of the welding notch.
7 . The backshell housing of claim 6 , wherein, at the interface, the thermoplastic material of the welding protrusion completely fills the welding notch.
8 . The backshell housing of claim 1 , wherein the welding protrusion and/or the welding notch has an essentially annular shape.
9 . The backshell housing of claim 1 , wherein, prior to joining by friction welding, the welding protrusion and/or the welding notch is coaxial with the cable passage.
10 . The backshell housing of claim 1 , wherein the housing parts are each formed as an injection molded component.
11 . The backshell housing of claim 1 , wherein the welding protrusion is integrally formed in a single piece with the second housing part.
12 . The backshell housing of claim 1 , wherein the welding notch extends from a front face of the first housing part into a frame of the first housing part.
13 . The backshell housing of claim 12 , wherein the welding notch extends around a circumference of the first housing part, and the welding protrusion extends around a circumference of the second housing part.
14 . The backshell housing of claim 13 , wherein the welding notch and the welding protrusion form the continuous section of the thermoplastic material at the interface around the circumference of the first housing part and the circumference of the second housing part.
15 . The backshell housing of claim 1 , wherein the continuous section of the thermoplastic material at the interface forms a rigid connection between the housing parts.
16 . A set for assembling a backshell housing, comprising:
a pair of housing parts including a first housing part and a second housing part friction welded to one another, each of the housing parts is formed of a thermoplastic material, a cable passage of the first housing part is continuous with a cable passage of the second housing part, the second housing part has a welding protrusion protruding axially from a front face of a flange of the second housing part, the front face of the flange is wider than the welding protrusion in a direction perpendicular to a longitudinal axis of the second housing part, the welding protrusion is received in a welding notch of the first housing part, the housing parts are friction welded at an interface of the welding protrusion and the welding notch to form a continuous section of the thermoplastic material at the interface that connects the housing parts.
17 . The set of claim 16 , further comprising an intermediate housing part friction welded between the housing parts.
18 . A method for assembling a backshell housing, comprising:
providing a pair of housing parts each having a cable passage, each of the housing parts is formed of a thermoplastic material, the housing parts include a first housing part and a second housing part, the second housing part has a welding protrusion protruding axially from a front face of a flange of the second housing part, the front face of the flange is wider than the welding protrusion in a direction perpendicular to a longitudinal axis of the second housing part, the welding protrusion is received in a welding notch of the first housing part; and
friction welding the housing parts to one another with the cable passage of the first housing part continuous with the cable passage of the second housing part, the housing parts are friction welded at an interface of the welding protrusion and the welding notch to form a continuous section of the thermoplastic material at the interface that connects the housing parts.
19 . The method of claim 18 , wherein the housing parts are welded together by spin welding.
