연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

An electrical connector includes an upper block, a lower block, and a terminal position assurance (TPA) element provided with at least one of the upper and lower blocks. The upper block is snappably joined to the lower block along a first direction when aligned in a pre-latched relation with one another. The upper and lower blocks are moveable in a second direction transverse to the first direction from a pre-latched position to a final seated position. The upper block includes a side latch that engages a rib on the lower block when the upper and lower blocks are joined. A shroud on the lower block engages the upper block and a boss at the forward end of the upper block is received in a retention slot on the lower block to inhibit disengagement of the upper block from the lower block when the upper and lower blocks are in the final seated position. The lower block includes a contact cavity that has a terminal retention beam. The terminal retention beam is deflectable from an initial position to a second position, elevated from the initial position to receive an electrical contact. The terminal retention beam returns to the initial position when the contact is fully inserted in the cavity.

1. An electrical connector comprising:an upper block;a lower block; anda terminal position assurance (TPA) element provided with at least one of said upper and lower blocks, said upper block being snappably joined to said lower block along a first direction when aligned in a pre-latched relation with one another, said upper and lower blocks being movable in a second direction transverse to said first direction from a pre-latched position to a final seated position. 2. The connector of claim 1 wherein said upper block includes a side latch that slidably engages a corresponding rib on said lower block when said upper block is joined to said lower block. 3. The connector of claim 1 wherein said lower block includes a shroud engaging said upper block to inhibit disengagement of said upper block from said lower block when said upper and lower blocks are in said final seated position. 4. The connector of claim 1 wherein said upper block includes a boss at a forward end thereof, said boss slidably engaging a retention slot on said lower block to hold said upper and lower blocks together when in said final seated position. 5. The connector of claim 1 wherein said lower block includes a contact cavity, said cavity including a terminal retention beam, said terminal retention beam being deflectable from an initial position to a second position elevated from said initial position in order to receive an electrical contact, said retention beam returning to said initial position when the contact is fully inserted in said cavity. 6. The connector of claim 1 wherein said TPA element includes a terminal retention beam configured to engage a step on a lower surface of said upper block and said retention beam is deflected to a position at which said retention beam inhibits movement of said upper block from said pre-latched position to said final seated position when an electrical contact is not fully inserted. 7. The connector of claim 1 wherein said upper block includes a latch beam on a lower surface thereof, said latch beam including a latch element engaging a pocket on an upper surface of said lower block to hold said upper and lower blocks in said final seated position. 8. The connector of claim 1 wherein said upper and lower blocks include a latch and rib extending along a length of said upper and lower blocks parallel to said second direction. 9. The connector of claim 1 further comprising a latch and rib combined with one another when said upper and lower blocks are joined together. 10. The connector of claim 1 further comprising a pair of latches provided on opposite sides of one of said upper and lower blocks, said latches facing one another. 11. The connector of claim 1 further comprising a pair of ribs extending along opposite sides of one of said upper and lower blocks. 12. An electrical connector comprising:an upper block, including a retention ledge on a lower surface thereof;a lower block joining said upper block, said upper and lower blocks being slidable relative to each other between a pre-latched position and a final seated position, said lower block including a contact cavity configured to receive an electrical contact; anda terminal retention beam attached to said lower block, said retention beam being biased toward said contact cavity, said upper block engaging said retention beam to inhibit removal of an electrical contact from said contact cavity when said upper and lower blocks are in said final seated position. 13. The connector of claim 12 wherein said terminal retention beam is connected to a rearward portion of said lower block, said terminal retention beam being deflectable from an initial position to a second position elevated from said initial position to receive the contact, said terminal retention beam returning to said initial position when the contact is fully inserted in said cavity. 14. The connector of claim 12 wherein said upper block includes a side latch slidably engaging a corresponding rib provided on said lower block. 15. The connector of claim 12 wherein said lower block includes a shroud partially covering a side latch provided on said upper block to inhibit disengagement of said upper block from said lower block when said upper and lower blocks are in said final seated position. 16. The connector of claim 12 wherein said upper block includes a boss at a forward end thereof, said boss being configured to slidably engage a retention slot on said lower block to hold said upper and lower blocks together when in said final seated position. 17. The connector of claim 12 wherein said upper block includes a latch beam on a lower surface thereof, said latch beam including a latch element at a rearward end thereof configured to engage a pocket on an upper surface of said lower block to hold said upper and lower blocks in said final seated position. 18. The connector of claim 12 wherein said retention beam is deflectable outward from said contact cavity when said upper and lower blocks are in said pre-latched position. 19. The connector of claim 12 wherein said upper block includes a retention ledge movable into an engaging relation with said retention beam when said upper and lower blocks are in said final seated position. 20. The connector of claim 12 wherein said upper block includes an opening, said retention beam being deflected upward into said opening in said upper block when said upper and lower blocks are in said pre-latched position.
