| 摘要 | An electrical snap-in terminal and brush housing and method of assembly are disclosed. The terminal blade member is provided with a plurality of mutually opposed resilient tongues arranged to contactively abut wall means of the brush housing to retain, in a first or blade insertion direction, the terminal blade member within the brush housing. The terminal blade member is also provided with an enlarged shoulder portion to define the position of the terminal blade member within the brush housing in a second or brush insertion direction. In order to aid in the assembly of the brush means within the brush housing, the housing includes an open end portion having the dimensions of a substantial portion of the terminal blade member so that the terminal blade member may itself be used to compressively confine the brush biasing means and, once the biasing means are sufficiently compressed, the brush housing is provided with means to receive the terminal blade member within suitably provided structure comprising a slot and notches in the brush housing so that the terminal blade member will be removably secured within the housing. | ||||||
| 权利要求 | 1. A method of assemblying a resiliently biased electrical brush within a brush housing comprising the steps of: inserting in a first direction the brush and biasing means within the housing; compressing the biasing means with an end of the terminal blade member to a degree sufficient compress all of the biasing means between the brush and an imaginary plane defined by the terminal blade member final position; sliding the terminal blade member generally perpendicular to the first direction until the end of the blade member enters a slot provided therefor in said housing and the shoulders of said blade member are aligned with notches provided therefor in said housing; and forcing said blade member end and said shoulders into said slot and notches, respectively, until resilient fingers of said terminal blade member move freely behind wall means of said housing. 2. The method of claim 1 wherein the step of forcing said blade member end and said shoulders is continued until widened shoulder portions abut the bottom of the housing notches. 3. The method of claim 1 wherein the step of sliding includes the step of rotating the terminal blade member to a position substantially perpendicular to the first direction to further compress the brush biasing means after the end of the terminal blade member has entered the slot. 4. The method of claim 1 wherein the terminal blade member has two substantially identical oppositely deposed brush biasing wall portions and the step of compressing includes the step of orienting either of the brush biasing wall portions to generally directed toward the brush. 5. A method of assemblying a resiliently biased electrical brush within a brush housing comprising the steps of: inserting the brush and brush biasing means with a housing channel in a first direction; contacting the free end of the brush biasing meaNs with a brush biasing wall portion of a terminal blade member, the brush biasing wall portion being generally perpendicular to the first direction; forcing the terminal blade member in the first direction to apply a compressive force to the brush biasing means; aligning the end portion of the terminal blade member with a slot provided therefor in a wall of the brush housing while aligning shoulder portions of the terminal blade member with notches provided therefor in opposite walls of the brush housing; and forcing the terminal blade member in a direction perpendicular to the first direction to cause the terminal blade member end portion and shoulder portions to enter the slot and notches, respectively. 6. The method of claim 5 wherein the step of forcing includes the step of moving the terminal blade member in the direction perpendicular to the first direction until resilient fingers on said terminal blade member move behind wall means of the brush housing. |
