Description
- The present invention relates to a two-part electrical connector.
- Two-part electrical connectors in which slide members are used to mate the two parts are well known. In general, the first part is secured in a panel and has a fixed terminal housing which protrudes a predetermined height away from the panel. The terminal housing has tabs which protrude therefrom. The second part, which contains the slide members, is positioned over the first part. For mating, the slide members are pushed, and the tabs engage in angled grooves in the slide members to pull the two parts together. In certain locations, the combined height of the second part and the terminal housing of the first part away from the panel, prior to mating, can be a critical issue.
- It is an object of the present invention to provide a two-part electrical connector in which the combined height, as specified above, prior to mating is reduced compared to prior art arrangements.
- A two-part electrical connector in accordance with the present invention is characterised by the features specified in Claim 1.
- In the present invention, the terminal housing of the first part, on which the tabs are mounted, is spring-loaded and movable in the mating direction. When the two parts are unmated, the terminal housing is retracted, reducing the height of the terminal housing away from the panel. On mating, the terminal housing is moved against the action of the spring loading. With this arrangement, the combined height of the second part and the terminal housing of the first part away from the panel, prior to mating, is smaller the equivalent height of the prior art arrangements.
- The present invention will now be described, by way of example, with reference to the accompanying drawings, in which:-
- Figure 1 is a side view of a prior art two-part electrical connector prior to mating of the two parts;
- Figure 2 is a side view of a two-part electrical connector in accordance with the present invention prior to mating of the two parts;
- Figure 3 is a cross-sectional view, from one end, of the two-part electrical connector of Figure 2 before the two parts are brought together for mating;
- Figure 4 is a cross-sectional view of the two-part electrical connector as shown in Figure 3 prior to mating (left-side) and when mated (right-side); and
- Figure 5 is a perspective view of one of the slide members of the second part of the electrical connector of Figure 2.
-
- Referring to Figure 1, the prior art two-part
electrical connector 10 comprises afirst part 12 and asecond part 14. Thefirst part 12 includes aterminal housing 16, and is mounted on apanel 18. Theterminal housing 16 is fixed and includes protrudingtabs 20. Thesecond part 14 includesslide members 22 which have angled grooves (not shown) for association with thetabs 20. In order to mate the twoparts second part 14 is positioned over theterminal housing 16 of thefirst part 12, thetabs 20 enter corresponding angled grooves in theslide members 22, and the slide members are pushed. Such action mates the twoparts second part 14 and theterminal housing 16 of thefirst part 12 away from the panel, prior to mating, have a combined height X. - In comparison, Figure 2 shows a two-part
electrical connector 100 in accordance with the present invention. The two-part connector 100 comprises afirst part 112 and asecond part 114. Thesecond part 114 is substantially unchanged from the prior artsecond part 14. Thefirst part 112, however, includes aterminal housing 116 which is movable in the mating direction. Theterminal housing 116 includes protrudingtabs 120 which are engageable in angled grooves in theslide members 122 of thesecond part 114, as detailed below. Theterminal housing 116 is biased inwardly in the unmated position, also as detailed below, thereby reducing the height of the terminal housing away from thepanel 118. As a consequence, the combined height Y of thesecond part 114 and theterminal housing 116 of thefirst part 112 is significantly reduced compared to the prior art. - Referring to Figure 3, the
first part 112 of the two-partelectrical connector 100 is mounted to extend through anaperture 124 in thepanel 118. Thefirst part 112 includes a fixedtubular housing 126 which is secured to thepanel 118, and which includes an inturnedlip 128 at the axial end remote from the panel. Theterminal housing 116 is positioned inside thefixed housing 126 and extends through theaperture 124 in thepanel 118 in an axial direction (the mating direction). Theterminal housing 116 has astop edge 130 which is engageable with the inturnedlip 128 of thefixed housing 126. Aspring 132 positioned between thefixed housing 126 and theterminal housing 116 act on the terminal housing to bias thestop edge 130 into engagement with the inturnedlip 128, when thefirst part 112 is not mated with thesecond part 114. Theterminal housing 116 has fourtabs 120, two on opposed sides, which project radially outwards from the terminal housing. Thetabs 120 are located adjacent theouter end 134 of theterminal housing 116. Theterminal housing 116 defines abore 136 which opens through, and axially extends from, theouter end 134 thereof. Located and secured inside thebore 136 of theterminal housing 116 are a number ofelectrical terminals 138. - The
second part 114 of the two-partelectrical connector 100 includes aconnector housing 140. A number ofelectrical terminals 142 are located and secured in theconnector housing 140 which are mateable with theelectrical terminals 138 of thefirst part 112. A pair ofchannels 144 is formed in theconnector housing 140 on opposed sides thereof. Thechannels 144 extend in a direction substantially perpendicular to the axial direction. Aslide member 122 is positioned in eachchannel 144. Theslide members 122 are slideable in thechannels 144 relative to theconnector housing 140. Eachslide member 122 has a pair of angled grooves 146 (Figure 5) formed therein which are open at oneend 148, and closed at theother end 150. - At the start of mating of the
first part 112 with thesecond part 114, eachtab 120 on theterminal housing 116 passes through theopen end 148 of a respectiveangled groove 146 to enter the groove, as shown on the left-hand side of Figure 4. Theslide members 122 are then pushed (slid) relative to theconnector housing 140. The movement of theslide members 122 draws thetabs 120 along theirrespective grooves 146 until the tabs reach the closedend 150, at which point the first andsecond parts - Because the
terminal housing 116 is axially movable relative to thefixed housing 126, the movement of thetabs 120 along thegrooves 146 during mating draws theterminal housing 116 out of the fixed housing against the bias of thespring 132, also as shown on the right-hand side of Figure 4, to bring theouter end 134 of the terminal housing into theconnector housing 140. For unmating of the first andsecond parts slide members 122 are moved in the opposite direction to push the tabs towards theopen ends 148 of thegrooves 146. During this action, theterminal housing 116 retracts under the bias of thespring 132 until thestop edge 130 engages the inturnedlip 128. - The present invention therefor provides a two-part
electrical connector 100 which is usable where height restrictions may be an issue.
