Electrical terminal blocks and assemblies thereof

The terminal block in accordance with claim l further comprising:

• first and second housing shells having first and second coupling sides, respectively, that extend between the mating face and the terminal end, each of the first and second housing shells comprising contact cavities extending from the mating face and along the longitudinal axis, the contact cavities being spaced apart along the lateral axis and configured to receive corresponding electrical conductors, the second housing shell having interior walls extending along the longitudinal axis that separate and define the contact cavities of the second housing shell;
• bores extending from the coupling side of the second housing shell and into corresponding interior walls;
• and
• locking pins projecting from the coupling side of the first housing shell, wherein the first and second coupling sides mate with each other along an interface when the first and second housing shells are coupled together, the locking pins being inserted into and forming interference fits with corresponding bores, the interference fits combining to form a rigid connection that mechanically holds the first and second housing shells together.

An electrical terminal block oriented with respect to longitudinal and lateral axes that extend perpendicular to each other, the terminal block comprising:

• a mating face and a loading surface being spaced apart from each other along the longitudinal axis and being configured to engage respective electrical conductors, the mating face extending along the lateral axis;
• and
• first and second housing shells having first and second coupling sides, respectively, the first and second coupling sides extending between the mating face and the terminal end, each of the first and second housing shells comprising contact cavities extending from the mating face and along the longitudinal axis, the contact cavities being spaced apart along the lateral axis and configured to receive corresponding electrical conductors, the second housing shell having interior walls extending along the longitudinal axis between the contact cavities of the second housing shell;
• bores extending from the coupling side of the second housing shell and into corresponding interior walls;
• and
• locking pins projecting from the coupling side of the first housing shell, wherein the first and second coupling sides mate with each other along an interface when the first and second housing shells are coupled together, the locking pins being inserted into and forming interference fits with corresponding bores, the interference fits combining to form a rigid connection that mechanically holds the first and second housing shells together.

An electrical terminal block assembly comprising:

• first and second terminal blocks, each of the first and second terminal blocks comprising:
• a mating face and a loading surface being spaced apart from each other along the longitudinal axis and being configured to engage respective electrical conductors, the mating face extending along the lateral axis;
• and
• first and second sidewalls facing in opposite directions and extending between the mating face and the loading surface, each of the first and second sidewalls including a wing member projecting therefrom along the lateral axis and a recess configured to receive a wing member from another terminal block, the wing members and the recesses having matching complementary cross-sections taken along the longitudinal axis;
• wherein the wing member of the first sidewall of the first terminal block is slidably and securely received within the recess of the second sidewall of the second terminal block.
