The invention relates to electrical connectors for connecting an electrically operable element to a source of electrical'energy.
The invention has for one of its objects to provide an improved electrical connector which is constructed to have an eflective water and air seal.
The invention has for other objects to construct the electrical connector with the sealing member bonded to the electrical contacts of the electrical connector and also to construct the electrical conductor. with the sealing member displaced into tight engagement with the shell of the electrical connector.
The invention has for a further object to provide an improved means for mounting the ele trical connector.
With these as well as other objects in view, the invention resides in the novel features of construction and combinations and arrangements of parts as more fully hereinafter set forth.
In the drawings:
Figure 1 is an end view of the electrical connector embodying the invention;
Figure 2 is a cross section on the line 2-2 of Figure 1.
The electrical connector comprises the metal shell I, the insulator body 2, the sealin device 3, the pressure device 4, and the electrical contacts 5, the insulator body, sealing device and pressure device being located within the shell.
The shell has the externally threaded end portions 5 and l, the internal annular flange 8 and the external annular flange 9. The internal annular flange provides the shoulders l and II which are spaced from each other longitudinally of the shell. The insulator body is in the nature of a plate and is formed with the holes I! extending longitudinally therethrough for receiving the electrical contacts 5. The insulator body also has the annular flange I! for overlying and engaging the annular shoulder In of the shell and the beveled surface It extending from the edge of the annular flange; I The annular flange I3 is preferably provided with an opening to receive the positioning pin l5 located in the internal annular flange 8.
The sealing device comprises the yieldable sealing member l8 and the insulator pressure plate H, the sealing member being preferably formed of synthetic rubber. The sealing member has a plate-like body portion at one side of the pressure plate I1 and engageable with the insulator body 2 and also has an annular flange portion encircling the pressure plate l1 and terminating in the 7 Claims. (Cl. 174-77) enlargement I 8 located within the annular recess I 9 at the periphery of the pressure plate. The pressure plate is formed with transverse holes in axial alignment with the holes l2 of the insulator body 2 to receive the electrical contacts 5., The sealing member [6 tightlyencircles and is bonded to the electrical contacts around their peripheries. The sealing member is bonded to the pressure plate to form the sealin unit, the bonding in both instances being effected as by vulcanizing the sealing member to the electrical contacts and pressure plate in a mold.
The pressure device 4 comprises the metal pressure ring 20 and the metal follower ring 2| abutting the pressure ring and externallly threaded to engage the internal threads 22 of the end portion 1 of the shell. The pressure rin preferably has a rounded face engaging the enlargement l8. The end portion 1 at the inner end of the internal threads 22 is provided with the internal annular recess 23 between the shell and the lower unbeveled edge of backing plate ll.
As shown in the present instance, the electrical contacts 5 are contact pins and they have the enlarged portions '24 and 25 located at the ends of the portions of the sealing member is which are bonded to the contact pins.
The end portion 6 of the shell is preferably provided with one or more pins 26 forming in effect a key for engagement with a keyway in the electrical element to be inserted into the end portlon whereby the contacts of the electrical element will properly engage the contact pins.
.The external annular flange 9 of the shell is used in clamping the electrical connector to the mounting plate 21 and this flange is formed with the annular serrations or teeth 28 which are imbedded in the yieldable sealing member 29 preferably formed of synthetic rubber. I have also preferably provided the pin 30 which extends transversely from the annular flange 9 through the sealin member and into a hole in the mounting plate, thispin serving to properly position the electrical connector on the mounting plate. Si is a clamping nut threaded upon the end portion '6 of the shell and abutting the mountin plate 21 and serving to effectively clamp the electrical connector to the mounting plate, at which time the yieldable sealing member forms an effective seal.
The construction of the electrical connector is such that after the insulator body 2, the sealing device 3 and the pressure device 4 have been inserted into the shell l and the follower ring 2! of the pressure device is tightened down, it exerts through the pressure ring 20 of the pressure device pressure directly upon the enlargement I I of the yieldable sealing member it and indirectly upon the pressure plate 11. As a result, the body portion of the sealing member i is urged firmly against the insulator body 2 and the annular shoulder II and the adjacent cylindrical face of the shell. Also the annular enlargement ll of the sealing member I6 is displaced to compel an additional portion thereof to enter the internal annular recess 23 in the shell and also to compel the adjacent portion of the annular enlargement to tightly engage the adjacent threads 22. It will thus be seen that an eirective water and air seal is provided since the sealing device tightly engages the shell and is bonded to the contact pins passing therethrough.
