Piston assembly and spring-loaded contact
A piston assembly for a spring-loaded contact, including: a piston body to be received into a housing of the spring loaded contact and having a first end to be connected directly or indirectly with an external part, a clip to mate with a conductive portion of the spring-loaded contact, wherein the piston body has a through hole, the clip being in the through hole.
1 . A piston assembly for a spring-loaded contact, including:
a piston body to be received into a housing of the spring-loaded contact and having a first end to be connected directly or indirectly with an external part,
a clip to mate with a conductive portion of the spring-loaded contact,
wherein the piston body has a through hole, the through hole extending longitudinally through the piston body and is configured to receive the clip
wherein the clip includes:
a clipping portion arranged to mate with the conductive portion of the spring-loaded contact,
a base end, opposite to the clipping portion, and
wherein the base end is located in the through hole on the side of the first end of the piston body.
2 . The piston assembly according to claim 1 , wherein the piston body has a length representing 65% to 100% of the length of the piston assembly.
3 . The piston assembly according to claim 1 , wherein the first end has a contacting surface to contact the external part directly.
4 . The piston assembly according to claim 3 , having a cap at least partially received in the through hole and closing the first end.
5 . The piston assembly according to claim 3 , wherein the piston body has a second end opposite the first end and wherein the clip protrudes partially from the second end.
6 . The piston assembly according to claim 1 , wherein the clip is press-fitted in the through hole.
7 . The piston assembly according to claim 1 , wherein the clipping portion extends from the base end in a direction opposite to the first end of the piston body.
8 . The piston assembly according to claim 1 , wherein the base end has a clip wall arranged to withstand a press fit force applied to the clip to insert the clip into the through hole.
9 . The piston assembly according to claim 1 , wherein the clip defines a through cavity.
10 . The piston assembly according to claim 1 , wherein the piston body includes a piston groove to accommodate at least part of a coil spring of the spring-loaded contact.
11 . The piston assembly according to claim 1 , wherein the conductive portion includes a pin portion for mating with the clip.
12 . The piston assembly according to claim 11 , wherein the pin portion and the piston assembly are configured so that the pin portion does not protrude out of the piston assembly.
13 . The piston assembly according to claim 1 , wherein the conductive portion includes a base portion for connecting another external part, an electronic or electric circuit.
14 . The piston assembly according to claim 13 , further comprising a base portion has a base groove to accommodate at least part of a coil spring of the spring-loaded contact.
15 . The piston assembly according to claim 14 , wherein the coil spring is located between the base portion and the piston body.
16 . The piston assembly according to claim 1 , wherein the housing includes an external bulge.
