Definitions
- the invention relates to an electrical connector with end contacts for high currents and in particular, but not exclusively, a single-pole connector.
- an articulated test finger defined according to a standard is used.
- the tests consist in not being able to make contact between the standard test finger and the live parts of the device to be tested by trying to introduce the test finger in all possible positions.
- protection can be obtained by protecting each live contact with a flap or by placing it very far back in an insulating envelope so that the test finger cannot reach it.
- the conductors and the contact elements in known devices have sections significant current flow, which are incompatible with protection only by the insulating envelope since the diameter of the contact elements becomes close to or greater than the maximum diameter of the test finger.
- the solution can consist in placing the contacts on a circle by making them inaccessible to the test finger by means of a rotating safety disc. This solution is in particular inapplicable to single-pole connectors which have their contacts in the center.
- the live contacts are the pins whose ends are protected by an insulator, as for example in the embodiment described in US Pat. No. 3,662,296.
- the electrical connection between the live spindle and the conjugate socket can be made on a part of the spindle which is not accessible by the test finger.
- the connector according to the invention is notably remarkable in that the penetrating part of the contact pin of the plug has a substantially constant cross section whose dimensions are at most slightly smaller than the dimensions of the cross section of the passage opening of the insulator of the base while the electric cable to which the pin is connected, has a cross-sectional area much greater than that of the penetrating part of said pin and, for example, at least twice as much.
- the opening for the passage of the insulation of the base is cylindrical while the diameters of said opening and of the penetrating part of the pin of the plug are less than 12 mm for, for example, a cable with a section greater than 70 mm 2 .
- the standardized test finger has a maximum diameter of 12 mm, and it is then understood that the connector according to the invention can easily successfully undergo the test of the test finger while allowing the use of high intensities.
- test finger has a shape reminiscent of a human finger and therefore thins towards its end. In this way, it is necessary to determine the right choice of the useful length of the spindle and its section.
- a diameter of the spindle of between 5 and 9 mm for a length of 6 to 15 mm, this length being all the greater the greater the said diameter, while the diameter of the insulation passage opening is slightly greater than that of the pin and that the thickness of the insulation to pass through is equal to the length of the penetrating part of said pin reduced by the length necessary for the additional compression desired for the elastic contact.
- the invention relates to unipolar connectors or not, it is particularly advantageous for constituting a unipolar device, the plug and the base then each comprising only one contact.
- the invention of course also relates to a plug or a socket taken separately intended to constitute a connector of the aforementioned type.
- FIG. 1 represents in section and partly a connector according to the invention, at the start of the connection maneuver,
- the connector shown in the drawings is here a single-pole connector comprising a base 1 and a plug 2 intended to couple together.
- the base 1 comprises an insulator 3 mounted in a casing 4 and in which a housing 5 is arranged for an elastic contact 6 under pressure.
- the elastic contact 6 in this example consists of a contact head 7 provided for example with a silver pad, a conductive braid 8 and a spring 9 so that the contact head 7 is movable by compression and expansion of said spring 9 and of the braid 8.
- the insulator 3 is provided with a cylindrical passage opening 10 open towards the outside.
- the base 1 which has just been described is intended to be coupled with the plug 2 of the connector, which plug is provided with a cylindrical contact pin 11 intended to constitute an end contact with the movable elastic contact 6 on the head 7 which the pin comes to bear as shown in the drawings, the pin 11 being here also provided like the head 7 with a silver chip at its end. Indeed, during the coupling of the plug 2 in the base 1, the pin
- the plug 11 of the plug is introduced into the insulator 3 through its passage opening 10 until it comes to contact the contact head 7 of the contact 6 which it causes, for example, to move back by 4 to 5 mm, that is to say say the length that has been determined for the desired additional compression of the movable elastic contact, the latter being already prestressed in its housing.
- Figure 1 shows the plug 2 in the base 1 at the start of connection while in Figure 2, the plug 2 is fully coupled, the connection being ensured.
- connection ring 12 an inner skirt 13 which cooperates with an annular seal 14.
- the base is here conventionally active, the movable elastic contact 6 being under electric voltage.
- the contact pin 11 of the plug which is intended to take the current is provided with a crimping head 15 (in one or more pieces) in which is crimped an electric cable 16, which is, for example, connected to a device electric to supply.
- the passage opening 10 has a sufficiently small diameter over a certain corresponding length. the thickness of the insulation there.
- the spindle 11 where at least the penetrating part thereof, must also have a diameter at most slightly less than that of the passage opening 10.
- the diameter of the pin 11, or at least its penetrating part has been greatly reduced compared to the diameter of the cable 16 which ensures the passage of a high current for a voltage greater than 50 volts.
- a cable 16 can be seen, the diameter of which is several times that of pin 11, a substantially identical cable also being shown in the drawings for the contact 6 of the base 1.
- the cable can thus have a cross section much greater than that of the pin, and, for example, approximately twice the cross section thereof for a current of 250 A.
- the maximum diameter of the insulating passage opening and its minimum thickness which corresponds to said penetration depth are thus known for a desired penetration depth.
- the maximum diameter of the spindle corresponds to the maximum diameter of the opening for passage of the insulation reduced by the clearance necessary for its introduction while its minimum length is equal to the minimum thickness of the insulation increased the additional crush length of the movable elastic contact.
- the inventor was able to determine pairs of values: (diameter of the insulation passage opening, thickness of the insulation) to which the pairs of values correspond: (diameter of the spindle, length of the spindle).
- the pairs of values correspond: (diameter of the spindle, length of the spindle).
- a diameter of the spindle of between 5 and 9 mm for a length of 6 to 15 mm, the length being all the greater the larger the diameter and more particularly still, in order to reduce heating as much as possible and therefore the length / surface ratio, the inventor proposes the following pair of advantageous values: a diameter of 6.7 mm for a length of 8 mm.
