Fan mounting arrangement with snap-type socket

Claim 2

In a mounting arrangement, particularly for mounting electrical motor wires in a fan, a combination comprising a housing having a cutout portion and a channel-shaped rib for receiving electrical motor wires; a socket member having an insert portion insertable into said cutout portion in predetermined direction and being formed with a slot for receiving said rib; and interengaging means on both of said portions for connecting the latter with snap-type action, including a resiliently yieldable element on one of said portions, said element being operative for resiliently engaging the other of said portions upon insertion in said predetermined direction, and also for resiliently disengaging from said other portion in direction opposite to said predetermined direction for disconnecting said portions from each other.

Claim 3

The arrangement of claim 1, wherein said interengaging means includes an abutment shoulder on said other portion and in juxtaposed relationship with said resiliently yieldable element.

Claim 4

The arrangement of claim 2, wherein said abutment shoulder has a bearing surface on which said resiliently yieldable element bears during insertion for urging said resiliently yieldable element between a disengaged position and an engaged position, said bearing surface being tapered and bounding with said resiliently yieldable element a space for receiving a demounting tool.

Claim 5

The arrangement of claim 1, wherein said socket member has a pair of spaced side walls extending along said predetermined direction, and a connecting wall intermediate and connecting said side walls, said connecting wall having a pair of passages spaced a predetermined distance from each other; and further comprising a pair of pins connectable with electrical motor wires and respectively receivable in said passages for mounting said pins relative to each other at said predetermined distance.

Claim 6

The arrangement of claim 4, wherein said connecting wall has wall portions which gradually taper in outward direction, as considered in direction normally to said predetermined direction.

Claim 7

The arrangement of claim 4; and further comprising means for fixedly securing said pins to electrical motor wires with application of heat, and wherein said socket member is constituted by high heat-resistant, thermoplastic synthetic plastic material.

Claim 8

The arrangement of claim 1; and further comprising means for guiding and for fixing said insert portion in said cutout portion, including a guide member on one of said portions and extending generally along said predetermined direction, and a guide groove on the other of said portions and also extending generally along said predetermined direction for receiving said guide member upon insertion.

Claim 9

The arrangement of claim 1, wherein said socket member has a leading end portion and a trailing end portion as considered along said predetermined direction, and wherein said socket member has a pair of spaced side walls extending intermediate said leading and trailing end portions.

Claim 10

The arrangement of claim 1, wherein said socket member is of one piece construction and is constituted by synthetic plastic material.

Claim 11

The arrangement of claim 1, wherein said cutout portion has a predetermined outline, and wherein said socket member has a trailing end portion of complementary contour to said predetermined outline.

Claim 12

The arrangement of claim 1, wherein said resiliently yieldable element has wall portions which gradually taper in outward direction, as considered in direction normally to said predetermined direction.

Claim 13

The arrangement of claim 1, wherein said socket member is constituted by synthetic plastic material composed of a mixture predominantly containing polycarbonate intermixed with glass fibers, said glass fibers amounting to at most 10% of the content of the mixture.

Claim 14

The arrangement of claim 1, wherein said resiliently yieldable element has a main resilient portion and a detent portion, said main resilient portion having a thickness of approximately 1 millimeter and a width of approximately 3.5 millimeters.

Claim 15

A socket member for mounting electrical wires in a housing, particularly in a fan housing in which electrical motor wires are to be respectively connected with pins, comprising a pair of elongated side wall surfaces extending lengthwise along a predetermined direction and being spaced from each other in direction transverse to said predetermined direction; an upper and a lower wall surface at respective opposite end regions of said side wall surfaces; a connecting wall on said lower-wall surfaces and extending towards said upper wall surface, said connecting wall also extending intermediate said side wall surfaces and connecting the latter; a resiliently yieldable element on said upper wall surface and operative for resiliently engaging the housing upon insertion of the socket member into the latter, and also for resiliently disengaging from the housing for disconnecting the socket member from the housing; a guide member on at least one of said side wall surfaces, said guide member extending generally along said predetermined direction and being operative for guiding the socket member into the housing; a fixing member on said lower wall surface, said fixing member extending generally along said predetermined direction and being operative for fixing the position of the socket member upon insertion into the housing; and a pair of passages on said connecting wall for respectively receiving the pins connected to the electrical wires, said passages extending through said connecting wall and being spaced along said predetermined direction relative to each other by a predetermined distance for mounting the pins and their connected wires at said predetermined distance relative to each other.

Claim 16

A socket member for mounting electrical wires in a housing, particularly in a fan housing in which electrical motor wires are to be respectively connected with pins, comprising a pair of elongated side wall surfaces extending lengthwise along a predetermined direction and being spaced from each other in direction transverse to said predetermined direction; an upper and a lower wall surface at respective opposite end regions of said side wall surfaces; a connecting wall on said lower-wall surfaces and extending towards said upper wall surface, said connecting wall also extending intermediate said side wall surfaces and connecting the latter; a resiliently yieldable element on said upper wall surface and operative for resiliently engaging the housing upon insertion of the socket member into the latter, and also for resiliently disengaging from the housing for disconnecting the socket member from the housing; a guide member on at least one of said side wall surfaces, said guide member extending generally along said predetermined direction and being operative for guiding the socket member into the housing; a fixing member on said lower wall surface, said fixing member extending generally along said predetermined direction and being operative for fixing the position of the socket member upon insertion into the housing; and a pair of passages on said connecting wall for respectively receiving the pins connected to the electrical wires, said passages extending through said connecting wall and being spaced along said predetermined direction relative to each other by a predetermined distance for mounting the pins and their connected wires at said predetermined distance relative to each other.
