Abstract

Abstract A connector includes a male terminal housing section having an opening for receiving a female terminal housing section of a counter-connector for connection between a male terminal disposed in the male terminal housing section and a female terminal disposed in the female terminal housing section. The connector further includes an insulator cap slidably disposed in the male terminal housing section. The insulator cap has a guide hole for the male terminal and is biased by a spring toward the opening of the male terminal housing section. The insulator cap is positioned forward of a tip of the male terminal relative to the opening of the male terminal housing section so that contact of an operator's finger to the tip of the male terminal is reliably prevented when, for example, fixing the connector. On the other hand, when the female terminal housing section is received in the male terminal housing section, the insulator cap is forced rearward away from the opening of the male terminal housing section against a biasing force of the spring while guiding the male terminal through the guide hole for connection to the female terminal. The insulator cap can be easily removed from within the male terminal housing section using an arrangement of tapers provided both on the insulator cap and on an inner wall of the male terminal housing section.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 176 words
A connector comprising: a connector body; a male terminal housing section provided in said connector body, said male terminal housing section having therein a male terminal extending toward an opening of said male terminal housing section, said male terminal housing section adapted for receiving a counter-female terminal housing section from said opening for connection between said male terminal and a female terminal disposed in said counter-female terminal housing section; and an insulator cap reciprocally slidable within said male terminal housing section and biased toward said opening by biasing means, said insulator cap having a first wall confronting said opening, said first wall having a guide hole for said male terminal and being located at a position forward of a tip of said male terminal relative to said opening, wherein said insulator cap is forced rearward within said male terminal housing section relative to said opening against a biasing force of said biasing means while guiding said male terminal through said guide hole when said female terminal housing section is received in said male terminal housing section.
Claim 2
Dependent Claim 176 words
A connector comprising: a connector body; a male terminal housing section provided in said connector body, said male terminal housing section having therein a male terminal extending toward an opening of said male terminal housing section, said male terminal housing section adapted for receiving a counter-female terminal housing section from said opening for connection between said male terminal and a female terminal disposed in said counter-female terminal housing section; and an insulator cap reciprocally slidable within said male terminal housing section and biased toward said opening by biasing means, said insulator cap having a first wall confronting said opening, said first wall having a guide hole for said male terminal and being located at a position forward of a tip of said male terminal relative to said opening, wherein said insulator cap is forced rearward within said male terminal housing section relative to said opening against a biasing force of said biasing means while guiding said male terminal through said guide hole when said female terminal housing section is received in said male terminal housing section.
Claim 3
Dependent Claim 40 words
The connector as set forth in claim 1, wherein said insulator cap is located at said position against the biasing force of said biasing means by stopper means provided on said insulator cap and within said male terminal housing section.
Claim 4
Dependent Claim 74 words
The connector as set forth in claim 1, wherein said insulator cap has a double tube structure having an outer tube and an inner tube which are connected by said first wall, wherein said outer tube is arranged to be slidable on an inner wall of said male terminal housing section, and wherein said inner tube forms said guide hole therethrough, said inner tube receiving and positioning therein the tip of said male terminal.
Claim 5
Dependent Claim 72 words
The connector as set forth in claim 1, wherein said insulator cap has a peripheral wall integral with said first wall, wherein said peripheral wall includes a flexible locking piece integral therewith, said flexible locking piece having a locking projection at its tip, and wherein said male terminal housing section is formed on its inner wall with a guide groove for engaging and guiding said locking projection of the flexible locking piece.
Claim 6
Dependent Claim 100 words
The connector as set forth in claim 4, wherein said first wall is formed with removing pin insertion holes radially outward of said guide hole, wherein said locking projection has a releasing taper at its one side and said guide groove has a corresponding releasing taper at its one side confronting said releasing taper of the locking projection, and wherein the engagement between said locking projection and said guide groove is released by turning said insulator cap toward said one side of the guide groove via said removing pin insertion holes when said insulator cap is located at said position.
