Abstract
Abstract This invention relates to a mounting socket for inductive proximity switches (1) of the type which comprises a number of guide pins (2) for cooperation with the socket when mounting and dismounting the proximity switch in the socket. The mounting socket comprises an inner, cylindric guide surface (10) corresponding to the body of the switch and this surface is provided with a number of guide slots (8), substantially in the longitudinal direction of the socket, for the guide pins (2) of the switch. The mounting socket also comprises a number of spring elements (16, 17, 18) which are arranged to cooperate with the guide pins (2) for locking the proximity switch at a very precisely defined position with respect to the sensed element (28). The spring elements (16, 17, 18) are formed by means of slots (19, 20, 21) having a substantially peripheral extension in a cylindric part (12) of an inner sleeve (5) seated in the housing. The slots (19, 20, 21) are provided with recesses at stop locations (23, 24, 25) corresponding to the guide pins (2) of the proximity switch when the proximity switch is located in its proper, locked position with respect to the sensed element (28).

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
184 words
A mounting socket for an inductive proximity switch of the type having a plurality of guide pins on an outer cylindrical wall for cooperating with the mounting socket when mounting and dismounting the switch in the socket and for locking the switch at a defined distance from an element to be sensed, said mounting socket comprising: a housing having a plurality of guide slots corresponding in number to the guide pins of the switch and located on an inner cylindrical wall for guiding the proximity switch towards and away from said sensed element, and, a spring part positioned in said housing and having a plurality of resilient spring elements corresponding in number to the guide pins of the switch, said spring elements being arranged to cooperate with the guide pins so as to lock the proximity switch in a stop position at a fixed precisely defined distance from the sensed element in which stop position movement of the switch towards the sensed element is prevented while movement of the switch away from the sensed element against the resilience of the spring elements is permitted.
Claim 2
Dependent Claim
184 words
A mounting socket for an inductive proximity switch of the type having a plurality of guide pins on an outer cylindrical wall for cooperating with the mounting socket when mounting and dismounting the switch in the socket and for locking the switch at a defined distance from an element to be sensed, said mounting socket comprising: a housing having a plurality of guide slots corresponding in number to the guide pins of the switch and located on an inner cylindrical wall for guiding the proximity switch towards and away from said sensed element, and, a spring part positioned in said housing and having a plurality of resilient spring elements corresponding in number to the guide pins of the switch, said spring elements being arranged to cooperate with the guide pins so as to lock the proximity switch in a stop position at a fixed precisely defined distance from the sensed element in which stop position movement of the switch towards the sensed element is prevented while movement of the switch away from the sensed element against the resilience of the spring elements is permitted.
Claim 3
Dependent Claim
67 words
A mounting socket according to claim 1 in which said housing is substantially an open tube comprising a first part provided with a cylindric guide surface corresponding to the outer cylindrical wall of the proximity switch and a second part in which an internal diameter is made larger than an internal diameter of said first part in order to admit an inner sleeve comprising said spring part.
Claim 4
Dependent Claim
32 words
A mounting socket according to claim 2 in which said guide slots are substantially parallel to the longitudinal axis of the socket and are made in a wall of said first part.
Claim 5
Dependent Claim
53 words
A mounting socket according to claim 1 in which said housing comprises substantially an open tube and said spring part comprises an inner sleeve, and in which said spring part is substantially cylindric and said spring elements are formed by slots having a substantially peripheral extension in a wall of the inner sleeve.
Claim 6
Dependent Claim
42 words
A mounting socket according to claim 4 in which said slots are inclined and extend downwards in said wall of the inner sleeve from an upper end surface of the inner sleeve so as to form a connection with said guide slots.
Claim 7
Dependent Claim
44 words
A mounting socket according to claim 4 in which said slots are provided with stop locations for receiving the guide pins of the proximity switch so as to lock the proximity switch in said precisely defined stop position with respect to said sensed element.
Claim 8
Dependent Claim
47 words
A mounting socket according to claim 2 in which said first and second parts of the housing are separated by a flange arranged to form a mechanical stop for said spring elements opposing excess motion of said spring elements in a direction away from said sensed element.
Claim 9
Dependent Claim
39 words
A mounting socket according to claim 6 in which the width of said slots is slightly smaller than the diameter of said guide pins and said stop locations comprise recesses in said spring part for receiving said guide pins.
