Electrical connector

Abstract

An electrical connector has a connect or shroud. A pin block disposed in the connector body supports a plurality of terminal pins that have head portions projecting out a forward end of the pin block and tail portions projecting out a rearward end of the pin block. The connector shroud has a socket at a forward end that receives a terminal stabilizer that is locked to the pin block to hold the terminal stabilizer and the pin block in assembly with the connector shroud to form a module. The module may include a block seal that can be sandwiched between the terminal stabilizer and the pin block during assembly of the module. The rear end of the connector shroud is truncated at an angle for a direct top down assembly of the module to a housing that has an attachment collar that is truncated at the same angle. The pin terminal tail portions are bent at a right angle and project through holes in a pin alignment member and a printed circuit board that are mounted inside the housing.

Claims

1. An electrical connector comprising; a connector shroud having a socket at a forward end for receiving a mating plug connector, an internal forward facing abutment wall and an internal rearward facing abutment wall,a pin block disposed in the connector shroud and abutting the internal rearward facing abutment wall of the connector shroud,a terminal stabilizer disposed in the connector shroud and abutting the internal forward facing abutment wall of the connector body,the terminal stabilizer having lock portions that engage lock portions of the pin block to lock the head stabilizer and the pin block together and retain the terminal stabilizer and the pin block in the connector shroud to form a module.

2. An electrical connector of claim 1 further including a block seal that is trapped between the pin block and the terminal stabilizer, the block seal having a plurality of through holes through which respective ones of the terminal pins extend project the block seal sealing around each of the terminal pins and having a peripheral sealing surface that sealingly engages an internal seal surface of the connector shroud.

3. The electrical connector of claim 1 wherein the lock portions of the head stabilizer comprise a plurality of alignment posts that extend rearwardly and that have slots, and wherein the lock portions of the pin block comprise flex arms that engage in the slots.

4. The electrical connector of claim 1 wherein the terminal pins have tail portions that are bent at a right angle, and wherein the electrical connector assembly includes a pin alignment member having a plurality of through holes through which the tail portions of the pin terminals project.

5. The connector assembly of claim 1 wherein the connector shroud has a rear end that is truncated at an angle and that has a peripheral mounting flange comprising generally horizontal upper and lower walls that are generally parallel and spaced from each other horizontally and vertically, and generally coplanar side walls that are slanted and that connect respective opposite ends of the upper and lower walls to form a continuous peripheral flange.

6. The electrical connector of claim 5 wherein the peripheral mounting flange has inner and outer locator grooves or interlocking with a mating surface surrounding a hole in an electronic housing when the electrical connector is attached to the electronic housing.

7. The electrical connector of claim 4 wherein the pin block has a knee that extends over the tail portions of the terminal pins.

8. A process for making an electrical connector comprising; providing a connector shroud having a socket at a forward end for receiving a mating plug connector, a forward facing abutment wall, a rearward facing abutment wall and an opening at a rearward end,inserting a pin block into the connector shroud through the opening at the rearward end,inserting a terminal stabilizer into the connector shroud through the opening at the forward end, andlocking the terminal stabilizer to the pin block so that the terminal stabilizer engages the forward facing abutment wall and the pin block engages the rearward facing wall to retain the terminal stabilizer and the pin block in assembly with the connector shroud.

9. The process as defined in claim 8 wherein the terminal stabilizer is locked to the pin block by posts that extend rearwardly from the terminal stabilizer and that have slots that are engaged by flex arms of the pin block.

10. The process as defined in claim 8 wherein a plurality of terminal pins extend through the pin block and the terminal stabilizer and wherein a block seal is inserted into the connector shroud so that the block seal is sandwiched between the pin block and the terminal stabilizer when the terminal stabilizer is locked to the pin block.

11. The combination comprising an electrical connector and a housing, the electrical connector having a connector shroud having a socket at a forward end for receiving a mating plug connector,a pin block disposed in the connector shroud and supporting a plurality of terminal pins that are arranged in horizontal rows that are vertically spaced with the terminal pins in each row being laterally spaced from each other,the terminal pins having head portions projecting out a forward end of the pin block and tail portions projecting out a rearward end of the pin block, andthe connector shroud having a rear end that is truncated at an angle,the housing having a collar that is truncated at an angle and that defines an opening,the truncated collar having a mounting wall that is engaged by the rear end of the connector shroud, andmeans to attach the connector shroud to the truncated collar of the housing.

12. The combination as defined in claim 11 wherein, the connector shroud has an internal forward facing abutment wall and an internal rearward facing abutment wall,the pin block abuts the internal rearward facing abutment wall of the connector shroud,a terminal stabilizer is disposed in the connector shroud and abuts the internal forward facing abutment wall of the connector shroud,the terminal stabilizer has a plurality of through holes through which respective ones of the head portions of the terminal pins extend,the terminal stabilizer has lock portions that engage lock portions of the pin block to lock the terminal stabilizer and the pin block together and retain the terminal stabilizer and the pin block in the connector shroud to form a module, andthe rear end of the connector shroud has a peripheral mounting flange comprising generally horizontal upper and lower walls that are generally parallel and spaced from each other horizontally and vertically, and generally coplanar side walls that are slanted and that connect respective opposite ends of the upper and lower walls to form a continuous peripheral mounting flange, andthe mounting wall of the truncated collar is engaged by the peripheral mounting flange of the connector shroud.

13. The combination as defined in claim 11 wherein, the rear end of the connector shroud has a peripheral mounting flange comprising generally horizontal upper and lower walls that are generally parallel and spaced from each other horizontally and vertically, and generally coplanar side walls that are slanted and that connect respective opposite ends of the upper and lower walls to form a continuous peripheral mounting flange, andthe mounting wall of the truncated collar is engaged by the peripheral mounting flange of the connector shroud.

14. The combination as defined in claim 13 wherein the mounting wall of the truncated collar has a continuous glue track and the peripheral mounting flange of the connector shroud is glued to the truncated collar of the housing.

15. The combination as defined in claim 14 wherein the mounting wall of the truncated collar has locating ribs that cooperate with inner and outer locating grooves to locate the peripheral mounting flange of the connector shroud with respect to the mounting wall of the truncated collar.

16.
