Definitions
- the invention relates to an electromagnetic relay with a narrow, elongated body made of insulating material, who defines a base level with its underside and on an electromagnetic system and a contact arrangement on its upper side carries, the contact arrangement contact carrier in the form of at least one fixed contact carrier and at least a movable, possibly connected to a spring support,
- Contact spring includes, the flat connecting lugs all in one common sheet metal plane parallel to the longitudinal axis of the base body and are perpendicular to the ground plane, which with a Middle section are anchored in the base body and their contacting end sections due to bends opposite each other with a predetermined contact distance stand, at least the fixed contact carrier in the material of the base body are embedded.
- the Invention a method for producing such a relay.
- the aim of the present invention is to make a narrow electromagnetic To create relays of the type mentioned and to provide a process for its manufacture, which at any contact configuration as make, break and always the same narrow, especially as a changeover contact Construction enables, at the same time, large insulation distances compared to the magnet system and a particularly simple Manufactured by arranging the connection lugs in one allows single sheet level; the connecting lugs should hanging at least partially on a circuit board in the Base body can be embedded.
- this goal is achieved with a relay of the named Art achieved in that all contact elements each with its central section in the area of anchoring in Base bodies are angled so that their contact End sections from their exit point from the base body in a single row, but in parallel, perpendicular to the base plane and to the level of the connecting lugs Levels stand, and that each contact spring in the direction of Longitudinal axis of the relay is operated.
- the relay according to the invention there are the contacts Sections of the contact carrier transverse to the longitudinal axis of the Relay, causing an actuation in the direction of this longitudinal axis becomes possible. Since the contact carrier in each case only in one Arranged in series is a narrow structure of the relay in guaranteed in any case, since the width depends on the extent of the Magnet system is determined and also a changeover contact Width not enlarged. There could even be two sets of contacts arranged one behind the other in the longitudinal direction of the relay and be operated by a longitudinal slide.
- the contact carriers are expediently in their main body anchored middle section at least by two perpendicular bending axes angled, whereby the Transition from the level of the connecting lugs to the respective one Contact level is accomplished, but at the same time a very material-saving Obtaining the contact carrier from the board is made possible. Due to the bend in the area of the Base body, the connecting lugs can be a desired have large isolation distances from each other while their contacting End sections the necessary short contact distance receive.
- the design according to the invention is particularly advantageous Realize contact arrangement in a relay in which the main body is a partition between the magnet system and the contact arrangement and one perpendicular to the bottom side Has insulating wall on a long side of the base body; in In this case, insulation is particularly favorable between the contact carriers and the magnet system if the level of the connecting lugs on one side in the area below the longitudinal insulating wall runs.
- a base body is molded from plastic, provided with the contact carriers, on this base body then an electromagnetic system is installed; according to the invention becomes at least one contact carrier from a sheet metal plate with a connecting lug, a middle section and a contact Cut end section so that it with its respective connecting lug still hangs on the circuit board, after that the middle section of each contact carrier bent out of the board level in such a way that the contact End section in its own, to the basic level and to the Board plane vertical plane stands, and then through Embedding the respective middle sections in plastic Base body shaped, after which the connecting lugs finally be separated from the sheet metal.
- 1 to 4 is the extraction of a relay body with contact arrangement by partial encapsulation of a sheet metal board shown in the various process steps. In doing so won from a board 1 two fixed contact carriers 2 and 3 and processed one after the other in the production run. So 1 and 2 show these fixed contact carriers in a first Process stage I and in a second process stage II.
- the fixed contact carriers 2 and 3 each cut free from the board. You own in each case a connecting lug 21 or 31, a central section 22 or 32 for embedding in the still to be described Base body and a contacting end section 23 or 33, already at this stage with a fixed contact 24 or 34 is provided.
- a connecting lug 21 or 31 for embedding in the still to be described Base body and a contacting end section 23 or 33, already at this stage with a fixed contact 24 or 34 is provided.
- the middle section 22 and 32 By bending the middle section 22 and 32 about mutually perpendicular bending lines 25, 26 and 27 or 35 and 36 the process stage II is reached, in which the two contacting end sections 23 and 33 opposite each other with their fixed contacts 24 and 34 in parallel stand.
- stage II again as seen in FIG which is followed by stage III.
- stage III In this stadium is by overmolding the middle sections 22 and 32 Plastic base body 4 of the relay formed the one hand over the connecting lugs 21 and 31 (shown in FIG 4) with the Circuit board 1 is connected, while on the other hand the end sections 23 and 33 of the fixed contact carrier made of plastic protrude from the main body.
- the bends of the fixed contact carriers are completely embedded in the plastic. Only those lying in the plane of the circuit board 1 are visible Terminal lugs 21 and 31 on the one hand and those in addition vertical contact-making end sections 23 and 33. This allows the fixed contacts with respect to the base body be positioned very precisely. Subsequent deformation the contact carrier is not required.
- the base body 4 forms a contact block 41, the large insulation distances with ribs and grooves to the magnet system.
- the base body 4 has a base plate 42, the underside of which defines a base level 11.
- insulation between the magnet system and the contact arrangement has the base body standing perpendicular to the base plate an insulating wall 43 and on one long side a longitudinal wall 44 that with a ceiling wall 45 a half-shell for receiving one end of the still magnetic system to be described.
- FIG 4 With a view of the base body from a opposite side can be seen in this case is between the two fixed contact carriers 2 and 3 a receiving slot 5 provided for the plug-in fastening of a contact spring 6.
- the contact spring itself is on a spring support 62 attached to a terminal lug 61, for example by spot welding.
- the spring support 62 is opposite its connecting lug 61 angled about a bending axis 65; besides that is Contact spring 6 around a bending axis 66 perpendicular thereto angled above.
- FIG. 5 shows the fully assembled relay. It is 4 after inserting the contact spring 6 a magnet system 7 with a coil 71, one Core yoke assembly 72 and an anchor 73 on the bottom plate 42 placed and from one long side into the through the Walls 43, 44 and 45 formed half-shell inserted. Since the Wall 44 the magnet system to one side to the contact system covers out, the terminal lugs 21, 31 and 61 are substantially below this longitudinal wall 44th in this way are the creepage distances from the connecting lugs to the open ones Side of the half-shell and thus in addition to the magnet system extended.
- a slide 8 transmits the switching movement of the armature 73 the end portion 67 of the contact spring 6, which makes the semicircular cut-out contacting section 63 of the Spring is actuated.
