- the coding element 175 interacts with a complementary coding element of a battery in a form-fitting manner.
- the batteries of the electrical device 10 on their wall section 178 each a projection designed complementary to the recess 176, which dips into the recess 176 of the device 100 when the battery is inserted into the respective battery receiving compartment 30, 31.
- the thrust part 104 has four contact bushings 180, 182, 184, 186 which are designed in the shape of a slot and which can each be penetrated by a first contact area 142 of the contact elements 134, 136, 138, 140.
- a collar 190 adjoins the free end of the rear wall 172 protruding from the contact surface 174 via a second step 188, on the underside of which the receiving sleeves 118, 120 are arranged. Between the receiving sleeves 118, 120, the collar 190 carries on its rear side 191 an essentially V-shaped latching bracket 192 which delimits a latching recess 194. This is particularly clear from FIG.
- two mutually parallel guide elements 196, 198 are arranged at a distance from one another and each with a receiving sleeve 118, 120 adjacent, which are each designed in the form of a guide rail 200, 202 and each in a guide channel 154 and 156, respectively of the base part 102 and are guided by the respective guide channel 154, 156.
- the contact elements 134, 136, 138, 140 can, as already mentioned, each with play in a recess 126, 128,
- the coil springs 110, 112 can be placed on the pin-shaped spring holders 114, 116.
- the push part 104 can then be mounted on the base part 102, the end areas of the helical springs 110, 112 facing away from the base part 102 being received by the receiving sleeves 118, 120 and the first contact areas 142 of the contact elements 134, 136, 138, 140 with their free ends each has an associated contact bushing 180, 182, 184, 186teurgrei fen and the locking projection 148 of the locking hook 146 in the locking recess 194 engages, engaging behind a locking edge 204 of the locking recess 194.
- the coil springs 110, 112 are somewhat tensioned when the base part 102 and the push part 104 are joined together, so that the base part 102 and the push part 104 are pressed apart and the push part 104 assumes a basic position relative to the base part 102 in which the first contact areas 142 of the contact elements 134, 136, 138, 140 protrude only slightly from the contact surface 174 and in which the latching projection 148 of the latching hook 146 rests on the latching edge 204 of the latching recess 194.
- the sliding part is shown schematically in this basic position.
- the thrust part 104 can counter to the spring forces exerted by the coil springs 110, 112, moved in the direction of the base part 102 who the. This has the consequence that the helical springs 110, 112 are tensioned further and the first contact areas 142 of the contact elements 134, 136, 138, 140 increasingly protrude from the contact surface 174.
- the movement of the push part 104 in the direction of the base part 102 can take place until the receiving sleeves 118, 120 of the push part 104 come to rest against stop surfaces 206, 208 of the base part 102. Of the stop surfaces 206,
- the device 100 forms a preassembled structural unit which, in the preassembled state, can be inserted in its entirety into an assembly area 46 of a battery receiving compartment 30, 31. Separate handling of individual components of the device 100 is not required when installing the device 100 in an assembly area 46.
- the onset of the Device 100 in a mounting area 46, 47 is thus very simple.
- the device 100 can be clamped in the basic position of the push part 104 between the upper edge 45 of a wall recess 42, 44 and the bottom wall 36 of the receiving housing 28, the upper edge 45 resting against the second step 188 of the push part 104 and the spring elements 106, 108 exert a clamping force in that the push part 104 and the base part 102 are slightly pressed together when they are inserted into a mounting area 46.
- the battery 32 can be inserted into the first battery compartment 30.
- the battery 32 can slide along the intermediate wall 38 until the wall section 178 of the battery 32 comes to rest on the contact surface 174 of the pushing part 104.
- the battery 32 then exerts a thrust force on the pushing part 104 which is opposite to the spring force of the helical springs 110, 112, so that the pushing part 104 is moved from its basic position into its contact position in which the first contact areas 142 of the contact elements 134, 136, 138,
- the first contact areas 142 can each dip into a contact recess 210 of the battery 32 arranged in the wall section 178 and contact an electrical connection element 212 of the battery 32. This makes it possible to electrically connect the battery 32 via the device 100 and via connecting lines, not shown in the drawing, of the high-pressure cleaning device 14 to its electrical device 12.
- the latching projection 52 arranged on the latching lever 50 dips into the associated recess 58 of the battery 32 so that it is locked in the battery compartment 30. If the battery 32 is to be removed from the battery compartment 30 again, the user can move the latching lever 50 from its locking position into its release position, so that the latching projection 52 releases the recess 58 of the battery 32. As a result, the battery 32 is lifted by the pushing part 104 so that it takes up a distance from the bottom wall 36 of the battery receiving compartment 30.
- the recess 58 of the battery 32 is offset so far from the opening 54 of the intermediate wall 38 that the locking projection 52 can no longer plunge into the recess 58 and thus an automatic renewed locking of the battery 32 in the battery compartment 30 is prevented .
- the user can then remove the battery from the battery compartment 30 without any further hindrance.
- the thrust force exerted on the thrust part 104 is omitted and the thrust part 104 automatically transfers to its basic position under the action of the spring force exerted by the helical springs 110, 112, in which the thrust part 104 has the first contact areas 142 of the contact elements 134, 136, 138 , 140 protects against external influences.
