Description

BACKGROUND OF THE INVENTION

The present invention generally relates to an electrical connector apparatus with a male housing and a female housing having a terminal position assurance device (TPA). More particularly, the invention is directed to ribs and other protective features provided on the male housing and the female housing to prevent the TPA from moving from a pre-set position to a final lock position. US 6,135,802 A and US 5,830,013 A describe variants of connectors.

SUMMARY OF THE INVENTION

The present invention relates to a female housing of an electrical connector apparatus according to claim 1, a male housing of an electrical connector apparatus according to claim 2, an electrical connector apparatus according to claim 3 and to a method for assembling an electrical connector apparatus according to claim 4.
At least a terminal is provided into each of the male housing and the female housing, when each of their respective TPA is at a pre-set position. The set of terminals provided for the male housing is secured thereto when the TPA thereof is placed at the final lock position. Similarly, the set of terminals provided for the female housing is secured thereto when the TPA of the female housing is placed at the final lock position. Thereafter, the male housing and the female housing may be engaged together.
To ensure that the TPA provided in the male housing and the TPA provided in the female housing of the electrical connector apparatus is not moved from a pre-set position to a final lock position during shipping and/or handling, the male housing and the female housing are provided with ribs to protect the TPA from physical contact. These ribs create a physical protective barrier to prevent the TPA from being moved from the pre-set position to the final lock position.
The electrical connector apparatus of the present invention is assembled and packaged in bags in bulk and shipped with the TPA in the pre-set position. This way, the operator can insert terminals into the electrical connector apparatus immediately upon receiving the electrical connector apparatus.
However, since the electrical connector apparatus is packaged and shipped in bulk, various parts can make contact with the TPA during shipping and/or handling which can cause an unprotected TPA from being moved from the pre-set position to the final lock position. If this occurs, the operator of the electrical connector apparatus will have to reset the TPA from the final position to the pre-set position in order to insert the terminals. This causes an inconvenience to the operator as well as wastes time when inserting the terminals into the electrical connector apparatus.
Additional features, advantages, and embodiments of the invention are set forth apparent from consideration of the following detailed description, drawings, and claims. Moreover, it is to be understood that both the foregoing summary of the invention and the following detailed description are exemplary and intended to provide further explanations without limiting the scope of the invention as claimed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIG. 1 is an exploded view showing the electrical connector apparatus of the present invention, generally referred to as reference number 1. The electrical connector apparatus 1 includes a male housing 2 and a female housing 3. TPA 4 is provided in the male housing 2 and TPA 5 is provided in the female housing 3. Additionally, FIG. 1 shows ribs 6, 7, 8, 9, 10, and 11 of the male housing 2.
Ribs 6, 7, 8, 9, 10, and 11are provided on the male housing 2 in order to protect the TPA 4 from any physical contact. Therefore, when the TPA 4 is set in the pre-set position during shipping, the ribs 6, 7, 8, 9, 10, and 11 will prevent the TPA 4 from moving to the final lock position. Furthermore, the ribs 6, 7, 8, 9, 10, and 11 are located on the periphery of the TPA 4 so as to protect the TPA 4 from all sides.
Furthermore, as can be seen in Figure 1, the male housing has a set of terminal apertures for receiving therein a set of other terminals. The male housing also comprises an opening for receiving the female housing.
FIG. 2A depicts a cross-sectional view of the male housing 2 in which the TPA 4 is in the pre-set position. This is the position in which the male housing 2 of the electrical connector apparatus 1 is shipped. FIG 2B shows a cross-sectional view of the male housing 2 in which the TPA 4 is in the final lock position. This final lock position makes inserting the terminals into the electrical connector apparatus more difficult for the operator; therefore, it is preferable that the TPA 4 is not moved to the final lock position during shipping.
FIG. 3A illustrates a cross-sectional view of the female housing 3 with the TPA 5 in the pre-set position. Similar to the male housing 2, this is the position in which the female housing 3 of the electrical connector apparatus 1 is shipped. FIG. 3B shows a cross-sectional view of the female housing 3 in which the TPA 5 is in the final lock position. As explained above, it is preferable that the TPA 5 is not moved to this final lock position during shipping and/or handling.
FIG. 4A illustrates a perspective view of the female housing 3 of the electrical connector apparatus 1 showing the TPA 5 in the pre-set position. TPA 5 is located on the bottom, or underneath,of the female housing 3 in a bottom slot. Additionally, the female housing has a set of terminal apertures for receiving therein at least a set of terminals.
FIG. 4A further shows ribs 12, 13, 14, 15, 16, 17, and 18 that are provided on the bottom side of the female housing 3 and that surround the TPA 5 so as to prevent the TPA 5 from being physically pressed down into the final lock position during shipping, handling, or at any other time prior to reaching the operator. The ribs 12, 13, 14, 15, 16, 17, and 18 are located on the periphery of the TPA 5 so as to protect the TPA 5 from all sides. FIG 4B shows the female housing 3 of the electrical connector apparatus 1 once the TPA 5 has been moved to the final lock position.
FIG. 5A illustrates a perspective view of the male housing 2 of the electrical connector apparatus 1 showing the TPA 4 in the pre-set position. As can be seen in FIG. 5A, when the TPA 4 is in the pre-set position, during shipping or at any other time, the TPA 4 is protected by the ribs 6, 7, 8, 9, 10, and 11 from all sides. These ribs 6, 7, 8, 9, 10, and 11 are located on the periphery of the TPA 4 so as to protect the TPA 4 from being pressed down into the final lock position. A perspective view of the male housing with the TPA 4 pressed down into the final lock position is shown in FIG. 5B.
FIG. 6, FIG. 7, FIG. 8A, FIG. 8B, FIG, 9A, FIG. 9B, FIG. 10A, FIG. 10B, FIG. 11A and FIG. 11B illustrate an electrical connector apparatus according to the second embodiment of the present invention.

Electrical connector apparatus 100 includes male housing 102, TPA 104, female housing 103, and TPA 105. Furthermore, Figure 6 shows the ribs 106, 107, 108, 109, 110, and 111 provided on the male housing 102 to protect the TPA 104.
Figure 7 is a perspective view depicting the male housing 102 of the electrical connector apparatus 100 with the TPA 104 in the pre-set position. Ribs 106, 107, 108, 109, 110, and 111 are provided on the male housing 102 so as to surround the TPA 104 along the periphery of the TPA 104. Ribs 106, 107, 108, 109, 110, and 111 protect the TPA 104 so that the TPA 104 is not moved from a pre-set position to a final lock position during shipping and/or handling.
Figure 8A illustrates a perspective view of the male housing 102 of the electrical connector apparatus 100 with the TPA 104 removed in order to fully see the placement of the TPA 104 in the male housing 102. Figure 8B shows the male housing 102 once the TPA 104 has been inserted into the male housing 102 and set in the pre-set position.
The female housing 103 is also provided with ribs 112, 113, 114, 115, 116, 117, and 118 to protect the TPA 103 from being moved from a pre-set position, as shown in Figure 11A, to the final lock position, as shown in Figure 11B. These ribs 112, 113, 114, 115, 116, 117, and 118 are located on the periphery of the TPA 103 so as to create a physical barrier to protect the TPA 103 from all sides.
