Abstract

A sealed electrical connector comprises two interengageable insulating bodies provided with embedded terminal plates for connection to respective cable conductors to be connected, each body having a respective depression filled with a gelatinous resin through which a contact pin connected to one terminal plate penetrates to make contact with the other terminal plate when the connector is assembled by clipping the two bodies together. Upon dismantling of the connector the gelatinous resin flows to reclose the holes made therein by the pin, thereby ensuring sealing of the terminal plates.

Claims

1. A connector adapted to effect a sealed and releasable connection between insulated conductors, said connector comprising, in combination:

a. a first rigid insulating impermeable body haviNg a working face formed with a depresssion;

b. a first metal plate embedded in said first body and extending from the depression through the first body, said plate having a first external terminal on the outside of the first body;

c. a contact pin electrically connected to said first plate and housed in the depression of the first body, said pin projecting beyond the plane of the said working face;

d. a layer of gelatinous resin filling the depression in the working face of the first body and entirely covering the contact pin;

e. a second rigid insulating impermeable body having a working face formed with a depression;

f. a second metal plate extending from the depression and through said second body, said second plate having a second external terminal on the outside of the second body;

g. a layer of gelatinous resin filling the depression in the second body; and

h. pressure means for pressing the two bodies against each other with their working faces facing each other, so that the contact pin carried by the first body perforates the layers of gelatinous resin in the two depressions to make contact with the plate in the depression of the second body.

2. The connector defined in claim 1, wherein the pressure means comprise a spring clip.

3. The connector defined in claim 2, wherein the spring clip has two rectilinear sections which press against the respective outer surfaces of the two bodies opposite their respective working faces, and an arched section which interconnects the two rectilinear sections.

4. The connector defined in claim 3 wherein the second body has a boss to which the spring clip is fixed.

5. The connector defined in claim 4, wherein one of the two rectilinear sections of the spring clip has means defining an opening which fits over the boss of the second body, said boss having a flanged head by which the spring clip is secured to the second body.

6. The connector defined in claim 1 wherein the first body has two lateral walls bounding the working face of said body and constituting a lateral guide for the second body.

7. The connector defined in claim 6, wherein the first body further has an end wall which constitutes an abutment engaged by the second body upon assembly of the connector.
