DETAILED DESCRIPTION

[0019] Example embodiments will now be described more fully with reference to the accompanying drawings.

[0020] Turning to the figures, a terminal block assembly is illustrated and designated with the reference numeral 10. The terminal block assembly 10 includes a terminal block 12 and one or more terminals 14. The terminal block 12 includes a retention member 16 that enables securement of the terminal block 12 to a support 18. Generally, the retention member 16 includes an aperture 20 that receives a fastener (not shown) to pass through the terminal block 12 to retain it on the support 18.

[0021] The terminal block base 12 includes at least one terminal receiving area 22, three are illustrated in FIG. 1. The terminal receiving area 22 receives the terminal 14. The terminal receiving area 22 includes a floor 24 with a pair of opposing sidewalls 26. The pair of opposing sidewalls 26 are substantially perpendicular to the floor 24 and define a channel to receive the terminal 14.

[0022] At the rear of the terminal receiving area 22, a pair of terminal lock members 28 project from the walls 26. Generally, the pair of lock members 28 oppose one another and are located over an aperture 30 in the terminal block 12.

[0023] The floor 24 defines a recess 32 that receives a block 34 secured to the terminal 14. A slot 36 is formed at the bottom of the recess 32 to enable a fastener 38 to pass through the terminal 14 and block 34 to secure with the terminal block 12, as seen in FIG. 3. Also, the terminal block 12 includes a rear wall 42 that includes a cutout 44 to receive the wire securement portion 62 of the terminal 14. The front of the terminal block receiving area 22 includes an opening 48 that enables positioning of the terminal 14 and sliding of the terminal 14 as will be described herein.

[0024] A pair of tabs 50 project from the sidewalls 26 of the terminal receiving area 22. The tabs 50 can be of any desired configuration as illustrated having an overall rectangular design. The tabs 50 receive the electrical terminal 14 as will be described herein. Generally the tabs 50 include an angled or tapered surface 52 to enable easy insertion of the terminal 14 onto the tabs 50.

[0025] The terminal 14 includes a base 60 with a wire connecting portion 62 and a locking mechanism 64. The base 60 is generally planar and includes an aperture 66 to receive the fastener 38 to secure the terminal 14 to the terminal block 12. The terminal 14 also includes a projecting finger 68 adjacent to the wire connector portion 62. The finger 68 engages the floor wall to prohibit longitudinal sliding movement forward once the terminal 14 is in a to be connected position, as will be described later.

[0026] The locking mechanism 64 includes an angled portion 70 angling away from the base 60. Generally, the angled portion 70 is perpendicular to the base 60. The angled portion 70 secures the block 34 in position in the recess 32 to enable the fastener 38 to pass through the base 60 and block 34 and into the slot 36. The angled portion 70 includes a pair of arms 72 that project outwardly towards the walls 26. Thus, a cutout 74 is formed at the lateral sides of the angled portions 70. The cutout 74 enables the tabs 50 to be received in the cutouts 74. Thus, the arms 72 are positioned on the bottom of the tabs 50 while the base 60 includes a portion positioned on top of the tab 50. Thus, as seen in FIG. 3B, the tabs 50 are sandwiched between the base 60 and locking portion arms 72. This prohibits up and down tipping or pitch movement of the terminal 14 once it is installed in the terminal block 12.

[0027] Turning to FIG. 5, another embodiment illustrates the arm 72 with a detent 74. The detent 74 registers with a recess 76 in the tabs 50 to position and lock the terminal 14 onto the tabs 50.

[0028] During insulation, the terminal 14 is positioned in the terminal block 12 as illustrated on the right hand side of FIG. 2. The terminal 14 is slid rearwardly into the position illustrated on the left side of FIG. 2. As this this occurs, due to the gap between the lock members 28 and floor 24, the terminal 14 slides underneath of the lock members 28 securing the terminal 14 against lateral sliding movement. Also, the finger 66 projects below the floor and will contact the wall of the floor to prohibit forward longitudinal sliding movement during assembly of the terminal 14 to the terminal block 12. As the terminal 14 is slid towards the rear wall 42, the arms 72 slide under the tabs 50 locking the front of the terminal 14 with the terminal block 12. This prohibits the terminal 14 from moving up and down or in a pitch direction on the terminal block 12. Thus, the terminal 14 is secured in the terminal block 12 against three degrees of movement. The fastener 38 is then passed through the apertures in the terminal 14 and block 34 until it is secured with the terminal block slot 36 as illustrated in FIG. 3. Thus, the terminals 14 are then securely positioned on the terminal block 12 to transfer the electrical power from the wires.
