Definitions
- the present invention relates to an electric connector device comprising a contact pin and a cable clip.
- the problem behind the invention is to provide a connector device having a contact pin/cable clip which guarantees a good electric contact between the cable clip and the contact pin as well as sufficient strength in the connection region between the clip and the pin.
- the pin should be mountable in structural members, for instance thin plate sheets, which are to be surface treated, for instance by-aggressive surface treating agents and/or lacquer, after the pin has been mounted.
- the connector device should be such that manual handling mounting failure sources are eliminated.
- the mounting should be simple and it should be possible to determine by a simple inspection whether the connection between the cable clip and the pin is correct or not.
- the connector device has to meet high standards of function as well as mass producion utility.
- the connector device should be useful - with advantage - as an earthing arrangement of thin plate sheet structural members of for instance motor vehicles, household machines, electric heaters, etc.
- British patent No. 121 442 330 discloses an arrangement of bendable pins insertable into a cable clip.
- contact pin is broadened to include also accumulator terminals, for instance
- British patent No. 1 288 001 discloses a cable clip arranged to be tightened by a locking screw on a conical accumulator terminal.
- pins require that specific measures are taken, for instance cleaning by a steel brush, after the sheet having the pin mounted thereon has been surface treated. Such a cleaning is not reliable enough to guarantee a long-term well operating earth connection. It is not possible to mount the known pins after a surface treating of the lacquering type, because the lacquer is destroyed and/or the mounting causes regions of corrosion.
- the clamping force of the screw union is small implying that the screw gets untightened.
- Lacquer of the screw union "sets" and contributes to the untightening of the screw union.
- the object of the invention is to obviate said drawback(s) and offer a more advantageous alternative.
- the invention provides an electric connector device comprising a contact pin and a cable clip for connection thereto.
- the device is characterized in that the contact pin is provided with a protective sleeve arranged for being removed after the pin has been mounted to a surrounding structural member, and in that the protective sleeve is arranged to cover at least an electric connection region of the pin.
- connection region comprises a conical region.
- the conical region is arranged to form a press union with the cable clip arranged for co-operation with the contact pin.
- the dimension relations preferably are such that the yield limit of the material of the collared part is passed when said press union is obtained.
- the pin preferably has a portion to be welded to the structural member, consisting for instance of thin plate. Other fastening methods are not excluded.
- the contact pin is arranged to form an earthing pin.
- the protective sleeve consists of metal meeting the required protection standards but also allowing a rational demounting. Plastics material withstanding for instance heat may also be used as material of the protective sleeve.
- the protective sleeve is arranged such that it prevents for instance surface treating agents, including lacquer for said structural member, from affecting the electric connection region of the contact pin.
- the contact pin denoted by 10 in Figure 1 consists of metal, for instance stainless steel, and has an upper truncated conical envelope surface 11.
- the envelope surface region of the contact pin continues in a generally cylindric attachment portion via a downwards conical portion 12.
- the cylindrical portion is arranged for being welded to a thin plate structural member 14 and therefore said portion is provided with a tip 16 for initiating the welding arc.
- a protective sleeve 15 consisting of a relatively soft metal, for example copper, in the embodiment shown.
- the fit between the sleeve 15 and the envelope surface 11 is made sufficient from a protective point of view with regard to aggressive, from an electric point of view detrimental surface treating agents, but such that simple demounting by axial removal is possible.
- the envelope surface 11 is shown uncovered, basically after two consecutive steps, namely welding of the contact pin 10 to the sheet 14 and lacquering of the structural member (generally involving a preceding further - surface treatment) by a lacquer layer 17.
- a portion 18 of the lacquer layer remains on the tip of the pin 10 after the protective sleeve has been drawn off.
- a rational drawing off is carried out by a puller.
- the welding is made for instance by an automatically loaded welding gun, where any contact pins for some reason lacking protective sleeves are discarded without action from the operator, implying that an otherwise doubtful source of failure is eliminated.
- the lacquer free portion 11 of the contact pin in Figure 2 forms the electric connection region.
- a collared cable clip 19 having a collar 20 dimensioned for press fit relative the pin surface 11 is shown in Figure 4.
- the material of the cable clip preferably is soft, for instance copper, brass, and the dimension of the collar and the pin surface 11 are such that the yield limit of the material of the collar is passed, at least partially, when the collar is mounted onto the pin.
- FIG. 3 there is shown a modified contact pin 10 provided with a protective sleeve 15.
- the transition region 12 is here extended and cylindric.
- the electric contact surface may comprise also the top surface of the contact pin, which requires a "cup"-shaped protective sleeve.
