Abstract
Abstract An improved pin terminal configuration obviates bowing and cracking of associate housings which often occurs with force fit insertion of standard pin terminals. The subject pin terminals are formed in pairs having compatible intermediate mounting portions with profiled enlargements and recesses which allow for corresponding displacement of and reception of housing material flowing as a result of the insertion process. The intermediate mounting portions are so spaced on the respective pin terminals as to lie substantially centrally of the thickness of the associate housing.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
216 words
A pin header having a housing of insulative material having first and second oppositely directed faces, a cavity formed in one of said faces defining a thin base, a plurality of pin apertures in said base extending between said cavity and the other of said faces, a plurality of pin terminals mounted in respective pin apertures of said header, each said pin terminal having a first mating portion lying in said cavity, a second mating portion extending beyond said other face, a board mounting portion in said second mating portion, and a retention portion lying within said aperture, said pin terminals being formed in a series of cooperating pairs of terminals, characterized by the first of each pair of pin terminals having a retention portion defining pairs of transverse enlargements equal distance from a centerline of the header base and the second of each pair of said pin terminals having a single transverse enlargement centered on said centerline of the header base so that material displaced by the pair of enlargements of the first of each pair of pin terminals flows above and below the single enlargement of the adjacent second of each pair of pin terminals while the material displaced by the single enlargement enters the area between the enlargements of the first pin terminal.
Claim 2
Dependent Claim
216 words
A pin header having a housing of insulative material having first and second oppositely directed faces, a cavity formed in one of said faces defining a thin base, a plurality of pin apertures in said base extending between said cavity and the other of said faces, a plurality of pin terminals mounted in respective pin apertures of said header, each said pin terminal having a first mating portion lying in said cavity, a second mating portion extending beyond said other face, a board mounting portion in said second mating portion, and a retention portion lying within said aperture, said pin terminals being formed in a series of cooperating pairs of terminals, characterized by the first of each pair of pin terminals having a retention portion defining pairs of transverse enlargements equal distance from a centerline of the header base and the second of each pair of said pin terminals having a single transverse enlargement centered on said centerline of the header base so that material displaced by the pair of enlargements of the first of each pair of pin terminals flows above and below the single enlargement of the adjacent second of each pair of pin terminals while the material displaced by the single enlargement enters the area between the enlargements of the first pin terminal.
Claim 3
Dependent Claim
31 words
A pin header according to claim 1 further comprising: at least one shoulder on said first mating portion adjacent said retention portion whereby staking forces are applied to said pin terminals.
Claim 4
Dependent Claim
23 words
A pin header according to claim 1 wherein said board mounting portion is a compliant section for solderless mounting in a circuit board.
Claim 5
Dependent Claim
161 words
Pin terminals for mounting in high density applications, said pin terminals formed in a continuous array of pairs comprising: a plurality of pairs of pin terminals stamped from a web of conductive stock, each pin terminal of each said pair of terminals, having first and second oppositely directed mating portions and an intermediate retention portion, characterized by the first of each pair of pin terminals having a pair of transverse enlargements equal distance from a centerline of the retention portion and the second of said pair of pin terminals having a single transverse enlargement centered on the centerline of said retention portion so that plastic material of an associate housing displaced by the pair of enlargements flows above and below the single enlargement of the adjacent pin terminal while the plastic material of said associate housing displaced by the single enlargement enters the area between the enlargements of the first pin terminal whereby overstressing and cracking of the housing are obviated.
Claim 6
Dependent Claim
161 words
Pin terminals for mounting in high density applications, said pin terminals formed in a continuous array of pairs comprising: a plurality of pairs of pin terminals stamped from a web of conductive stock, each pin terminal of each said pair of terminals, having first and second oppositely directed mating portions and an intermediate retention portion, characterized by the first of each pair of pin terminals having a pair of transverse enlargements equal distance from a centerline of the retention portion and the second of said pair of pin terminals having a single transverse enlargement centered on the centerline of said retention portion so that plastic material of an associate housing displaced by the pair of enlargements flows above and below the single enlargement of the adjacent pin terminal while the plastic material of said associate housing displaced by the single enlargement enters the area between the enlargements of the first pin terminal whereby overstressing and cracking of the housing are obviated.
Claim 7
Dependent Claim
27 words
Pin terminals according to claim 4 further comprising at least one shoulder on each pin terminal adjacent said retention portion against which a staking force is applied.
Claim 8
Dependent Claim
31 words
Pin terminals according to claim 4 further comprising a compliant mounting section adjacent said intermediate retention portion whereby said terminals can be mounted in a circuit board in a solderless fashion.
