Abstract
Abstract An electrical connector header assembly adapted for mounting on a printed circuit board so as to allow multi-directional mating contact with a complementary connector receptacle assembly includes a box-like insulated housing with contact receiving cavities therein. Each of the cavities is generally planar and is open to the front, rear and bottom surfaces of the housing, with the main portions of the cavities being parallel to each other and to the lateral surfaces of the housing. Each cavity also has a second, subsidiary, portion extending laterally from the main portion and open to the rear surface. The assembly further includes electrical contacts received in respective ones of the cavities. Each of the contacts is generally planar so as to fit within the planar cavity except for the laterally bent tab which extends into the cavity second portion. Each contact has a forward blade portion which extends beyond the front surface of the housing and which also extends beyond the bottom surface of the housing. Thus, the cavity being open along the bottom surface of the housing allows the contact to be inserted blade portion first from the rear surface of the housing. The bent tab prevents vertical movement of the contact and interference between the forward edge of the tab and a front wall of the cavity second portion limits forward movement of the contact. Interference members prevent rearward movement of the contact.

Claim 1
Independent Claim
298 words
An electrical connector header assembly adapted for mounting on a circuit board so as to allow multi-directional mating contact with a complementary connector receptacle assembly, comprising: an insulated housing of generally hexahedral shape having a front surface, a rear surface, a top surface, a bottom surface and a pair of lateral surfaces, the housing having at least one contact receiving cavity therein, each of the at least one cavity having a generally planar first portion open to the front, rear and bottom surfaces of the housing, the plane of the first portion being substantially parallel to said pair of lateral surfaces, and each of the at least one cavity having a second portion extending laterally from said first portion and open to said rear surface; and at least one electrical contact received in a respective one of said at least one cavity, each of said at least one contact including a blade portion, a body portion and a terminal portion, the body portion having a generally planar main portion within the respective cavity first portion and a laterally bent tab extending from said body main portion into the respective cavity second portion, the terminal portion being generally co-planar with said body main portion and extending out of said respective cavity beyond said housing bottom surface, and said blade portion being generally co-planar with said body main portion and extending out of said respective cavity beyond said housing front surface, that part of said blade portion which extends out of said respective cavity having a lower edge spaced vertically beyond said housing bottom surface; wherein said at least one contact is inserted blade portion first into said respective cavity from said housing rear surface, with said blade portion extending out of said respective cavity beyond said housing bottom surface.

An electrical connector header assembly adapted for mounting on a circuit board so as to allow multi-directional mating contact with a complementary connector receptacle assembly, comprising: an insulated housing of generally hexahedral shape having a front surface, a rear surface, a top surface, a bottom surface and a pair of lateral surfaces, the housing having at least one contact receiving cavity therein, each of the at least one cavity having a generally planar first portion open to the front, rear and bottom surfaces of the housing, the plane of the first portion being substantially parallel to said pair of lateral surfaces, and each of the at least one cavity having a second portion extending laterally from said first portion and open to said rear surface; and at least one electrical contact received in a respective one of said at least one cavity, each of said at least one contact including a blade portion, a body portion and a terminal portion, the body portion having a generally planar main portion within the respective cavity first portion and a laterally bent tab extending from said body main portion into the respective cavity second portion, the terminal portion being generally co-planar with said body main portion and extending out of said respective cavity beyond said housing bottom surface, and said blade portion being generally co-planar with said body main portion and extending out of said respective cavity beyond said housing front surface, that part of said blade portion which extends out of said respective cavity having a lower edge spaced vertically beyond said housing bottom surface; wherein said at least one contact is inserted blade portion first into said respective cavity from said housing rear surface, with said blade portion extending out of said respective cavity beyond said housing bottom surface.
Claim 3
Dependent Claim
71 words
The header assembly according to claim 1 wherein the upper edge of said at least one contact is formed substantially as a straight line, and said at least one contact body main portion is formed with at least one rearwardly directed barb on said upper edge to engage an upper wall of said respective cavity first portion and interfere with removal of said at least one contact from said respective cavity.
Claim 4
Dependent Claim
52 words
The header assembly according to claim 1 wherein said at least one contact tab is formed with at least one rearwardly directed barb on a distal edge to engage a side wall of said respective cavity second portion and interfere with removal of said at least one contact from said respective cavity.
Claim 5
Dependent Claim
65 words
The header assembly according to claim 1 wherein said respective cavity second portion has formed on each of a pair of opposed wall surfaces a rib extending into said respective cavity second portion, each of said ribs being elongated in a direction substantially parallel to said housing lateral surfaces, wherein said pair of ribs provide an interference fit for said at least one contact tab.
Claim 6
Dependent Claim
79 words
The header assembly according to claim 4 wherein said at least one contact tab extends orthogonally to said at least one contact body main portion, said respective cavity second portion extending orthogonally to said respective cavity first portion so as to have an upper wall and a lower wall each with one of said pair of ribs thereon, and said pair of ribs are opposed one to the other in a plane substantially parallel to said housing lateral surfaces.
Claim 7
Dependent Claim
47 words
The header assembly according to claim 1 wherein said respective cavity second portion has a front wall against which a forward edge of said at least one contact tab abuts to provide a forward limit for insertion of said at least one contact into said respective cavity.
Claim 8
Dependent Claim
104 words
The header assembly according to claim 1 wherein said housing further includes a pair of forwardly extending planar side walls, each of said side walls having an outer surface co-planar with a respective housing lateral surface, and each of said side walls having a horizontal dimension and a vertical dimension each at least as great as the respective largest horizontal and vertical dimensions of that part of said at least one contact blade portion which extends out of said respective cavity so that an orthogonally lateral image projection of said at least one contact blade portion is entirely contained on said each side wall.
Claim 9
Dependent Claim
121 words
The header assembly according to claim 1 wherein there are a plurality of parallel side-by-side contact receiving cavities in said housing and an equal plurality of electrical contacts each in a respective one of said cavities, each of the contacts being in either a first group of at least one contact or a second group of at least one contact, and the blade portion of each of the contacts in said first group extends further beyond said housing front surface than the blade portion of each of the contacts in said second group so that the contacts of said first group make before and break after the contacts of said second group when mating and unmating, respectively, with said receptacle assembly.
