Definitions
- the invention relates to a contact protection housing for at least one electrical connection, which is arranged in a housing part, which is attached to a component and in which an opening for filling in potting compound is recessed.
- the invention also relates to an injection pump with a contact protection housing.
- the invention also relates to a method for mounting a contact protection housing with the aid of an adapter.
- a contact protection housing which consists of two assembled housing parts.
- a seal is arranged between the two housing parts.
- the seal serves to retain potting compound that has not yet solidified when filling.
- the seal must be positioned exactly when assembling the contact protection housing.
- the seal is also prone to wear.
- An object of the invention is to provide a contact protection housing which is formed from fewer individual parts than conventional ones
- a contact protection housing for at least one electrical connection, which is arranged in a housing part, which is attached to a component and in which an opening for filling in potting compound is cut, in that the housing part is formed by a thin-walled cap, the Edge is under constant tension on the component.
- Contact protection housing is characterized in that the cap has the shape of a cylinder which is open on one end face, on the outer surface of which a tapered nose is provided, the flanks of which are slightly concave.
- the concave design leads to an elastic adaptation of the flanks of the cap to the component. This allows production-related tolerances of the component to be compensated for.
- the cavity is vented automatically during casting via the remaining small gaps between the line holder and
- the object is achieved in a method for mounting a previously described contact protection housing on a component, in particular on a previously described injection pump, the casting compound being filled in with the aid of a nozzle, in that an adapter is arranged between the cap and the nozzle when the casting compound is filled in becomes.
- the adapter is used to separate the nozzle from the cavity. The distance between the cap and the nozzle, which is forced by the adapter part, prevents the potting compound from being thermally decomposed in the area of the filling opening in the cap.
- the method is characterized in that the adapter has a through bore with a first section, the diameter of which is larger than the diameter of the opening in the cap for filling in the casting compound, and with a conical second section which tapers from the inside to the outside.
- the first section is used to compensate for inaccuracies when attaching the nozzle to the cap. This ensures that the cap is properly filled even if the nozzle opening is not arranged exactly concentrically with the cap opening.
- the molding compound remaining outside the cap in the region of the cap opening after the filling process forms a button which is integral with the molding compound in the interior of the cap.
- the button has a larger diameter than the opening in the cap and thus prevents the cap from loosening and being accidentally removed after assembly.
- the conical second section of the adapter is used to seal and center the fill nozzle.
- a further embodiment of the adapter according to the invention is characterized in that a cylindrical third section is arranged between the first and the second section.
- the connection can also be tapered with a taper in the direction of the nozzle and / or profiled.
- the third section allows the passage of the
- the distance between the nozzle and cap can be varied over the length of the third section.
- the size of the distance between the nozzle and the cap depends, among other things. on the temperature of the nozzle when filling.
- Figure 2 shows the contact protection housing from Figure 1 in the filled state
- Figure 4 shows an enlarged section of the contact protection housing shown in Figure 3.
- a solenoid valve 1 is shown, which is mounted with the help of a (not shown) clamping screw on a (also not shown) distributor injection pump. There is a line holder on the solenoid valve 1
- the line holder 2 comprises a fixing aid
- the line holder 2 and the fixing aid 3 serve to receive electrical lines 4.
- the electrical lines 4 are arranged in the line holder 2 in such a way that they are positioned as close as possible to the contact lugs 5 emanating from the solenoid valve 1.
- the line holder 2 is fastened to the solenoid valve 1 with the aid of a screw 6.
- connection points of the solenoid valve 1 are surrounded by a cap 7, in which an opening 8 is recessed.
- the opening 8 in the cap 7 serves to fill the hollow interior 9 of the cap 7, which is also referred to as a cavity, with a casting compound.
- the cavity 9 is filled with potting compound.
- the potting compound is filled in through a nozzle 10.
- An adapter 14 is arranged between the nozzle 10 and the cap 7 of the contact protection housing according to the invention. The adapter 14 thermally removes the cap 7 from the nozzle 10 decoupled.
- the adapter 14 has a central through bore with a first section 11, a second section 12 and a third section 13.
- the third section 13 has the shape of a circular cylinder and is arranged between the first section 11 and the second section 12.
- the connection can also be tapered with a taper in the direction of the nozzle and / or profiled.
- the third section 13 forms a sprue 16 when the potting compound is injected and is removed after assembly.
- the second section 12 is conical and serves to receive the tip of the nozzle 10.
- the first section 11 of the through hole in the adapter 14 is also conical.
- the two cones in the sections 11 and 12 of the adapter 14 both taper towards the middle section 13, which has the smallest diameter of the three sections.
- the potting compound forms a button 15 in the interior of the first section 11.
- the button 15 has an outside diameter that is larger than the inside diameter of the bore 8 in the cap 7.
- the cap 7 has a cylindrical outer contour 20 on which a triangular nose is formed, the flanks of which are designated by 21 and 22.
- the tip of the nose is flattened.
- the area of the flank 21 of the cap 7 from FIG. 3 is shown enlarged in FIG.
- the flank 21 of the cap 7 is in the installed state on the housing of the solenoid valve 1.
- the solenoid valve 1 must be fastened to the distributor injection pump with the help of the concentrically arranged clamping hollow screw with a high tightening torque.
- a cable tail on solenoid valve 1 would be exposed to a very high risk of damage.
- the solenoid valve 1 therefore only has two projecting contact tabs 5 for later contacting. Because of the high demands in operation, the contact should be designed to be non-detachable. It must be adequately protected against mechanical stress and media. All work steps for contacting must be carried out in a predetermined short assembly cycle. All of these requirements are met by the invention.
- the assembly of the contact protection housing according to the invention proceeds as follows.
- the solenoid valve 1 is screwed onto the distribution injection pump (not shown). Then the line holder 2 with the electrical lines 4 is plugged onto the exposed end face of the solenoid valve 1. The two contact tabs 5 of the solenoid valve 1 are guided through corresponding openings in the line holder 2. The wire ends of the electrical lines 4 are arranged and fixed in such a way that they are always at a short distance from the contact tabs 5.
- the line holder 2 is screwed to the solenoid valve 1 using the screw 6.
- the contact between the strand ends of the electrical lines 4 and the contact lugs 5 is then produced by resistance welding. Soldering or other welding processes are also possible.
- the cover cap 7 is pressed onto the solenoid valve 1 and the line holder 2 until the bottom of which comes to rest on the line holder 2.
- the covering cap 7 is designed such that the edge of the cap is in constant contact with the solenoid valve 1 and the hump-shaped fixing aid 3.
- the cavity 9 inside the cap 7 is filled with potting compound.
- Hotmelt adhesive which is applied with overpressure, is used as the potting compound.
- Hot melt adhesive has the advantage that no additional heat input or a long reaction time at room temperature are required.
- other casting compounds can also be used within the scope of the present invention.
- a visible shape 15 remains, which is also referred to as a button.
- the button creates a form fit for axially fixing the cap 7 as a support for frictional engagement after pressing. Due to the adhesion of the potting compound to the cap 7, this is additionally held and vibration-damped.
- Another task of the sealing compound is to secure the fastening screw 6 of the line holder 2, the insulation, the contacts with one another and against ground, the protection of the contacts against media and the filling of small cavities and undercuts to avoid suction.
- both the advantages of mounting the solenoid valve 1 to the pump without the use of cable tails and the known high level of functional reliability of the cable tail contacting during operation can be used.
- the construction according to the invention can be used on small assemblies and on complete products. The required assembly operations can be integrated into a short-cycle line assembly.
- the (not shown) clamping screw of the solenoid valve 1 is caught under the cover cap 7, since the cover cap 7 has larger radial dimensions than the solenoid valve 1.
- the cover cap 7 can only be removed in connection with mechanical damage.
