Definitions
- the invention relates to an electrical connector between at least one winding of the stator Electric motor and a circuit board of the electric motor controlling electronics, with one on a first electrical solder contact soldered to the circuit board Plug, which in the assembled state in one with the Windings connected socket is inserted, the Plug a second via a flexible connection has electrical solder contact to the circuit board.
- Connectors provided on printed circuit boards are well known.
- a sheet metal strip is attached to the PCB soldered, which acts as a connector and which in a clamping contact acting as a socket can be inserted is. It is important that the sheet metal strip in the essentially perpendicular to the surface of the circuit board protrudes so stiff that he is at the Installation by inserting it into the terminal contact occurring forces can absorb.
- solder connection between the metal strip and the Printed circuit board Due to vibrations when operating the electric motor Solder connection between the metal strip and the Printed circuit board considerable mechanical loads exposed, especially with older solder connections and / or at higher temperatures can lead to the fact that the solder joint is damaged or completely loosened. This break in the electrical connection between leads the stator windings and the electronics unit to the failure of the electric motor, possibly causing further damage can occur.
- the connector according to US-A-5 632 629 are indeed two solder contacts truncated from each other possible but not systematically.
- the object of the invention is therefore a constructive simple and easy-to-use plug connection of the to create the type mentioned above, both a sufficient strength to absorb the assembly forces as also a permanently secure and against external mechanical Has insensitive electrical connection and to manufacture and close them quickly and inexpensively assemble.
- the sheet metal strip is slotted at its lower end in such a way that it has the two solder contacts each at one end of a partial strip has, which are opposite the end forming the plug. This makes a particularly simple and cost-effective production from a single sheet metal blank through one in a single step executable punching and bending process.
- the Sheet metal strips at its lower end two or more Have slots such that it has three or more Has partial strips, each with a solder contact on their Have the end that the end forming the plug opposite.
- the individual partial strips can each be designed as a rigid or flexible area, wherein at least one rigid and at least one flexible area is available.
- first Solder contact in a central area of the metal strip arranged between the second solder contact and the plug is.
- the metal strip is not in partial strips slotted, but as a single continuous stripe educated.
- a special one Flexibility can be achieved in that the curved Area of the metal strip in the form of a zigzag line or is curved in a wavy line.
- Figures 2 to 4 are in side view ( Figure a) and in Front view ( Figure b) shown.
- the circuit board 1 shown schematically in FIG. 1 (PCB, ceramic substrate or IMS substrate with Conductor pattern) is not closer to the housing 2 shown electric motor used.
- the circuit board 1 On the circuit board 1 are the individual components 3 of the electric motor controlling electronics arranged and through each other Solder connections connected.
- the contact with the windings of the stator of the electric motor is via an inventive electrical connector produced, of which in figure 1 a connector 4 is shown schematically.
- the plug 4 consists of a bent sheet metal strip, the one with a first foot region 5 via a solder connection 6 electrically connected to the components 3 of the circuit board 1 is.
- the socket 8 in turn is with a winding of the stator of the electric motor electrically connected. You can use multiple windings each a separate socket 8 or a single common Socket 8 may be provided.
- a second foot region 9 of the plug 4 is also over soldered a solder joint 10 to the circuit board 1 and electrically connected to the electronic components 3.
- about the bent sheet metal strip area 11 is the second foot area 9 with the first foot area 5 of the Connector 4 flexibly electrically connected.
- connector 4 shown in Figure 2 is a only, relatively narrow sheet metal strip bent in such a way that its one end portion the long leg 7 to Inserting into the socket 8 forms an adjacent area forms the first foot region 5 and the other end region forms the second foot region 9.
- the flexible connection 11 is between the two foot areas 5 and 9 also through the multiple back and forth Metal strips formed.
- FIG. 3 shows a particularly preferred embodiment of the connector 4 shown, which is made of a relatively wide There is a metal strip. Below the in the socket 8 insertable, wide upper area 7 is the Sheet metal strips through a slot 12 in two relative narrow partial strips 13 and 14 as sheet-metal strip extensions divided. A shorter partial strip 13 has on its End of the first foot region 5 for the first solder connection 6 while a second partial strip 14 at the end of the second foot region 9 for the second solder connection 10 having. The second partial strip 14 is in his lower area 15 at angles zigzag or with Roundings waved back and forth to point to this Way to form the flexible connection 11.
- the partial strip 14 with the flexible connection 11 has a greater length than the adjacent partial strip 13, the however, due to the zigzag-shaped bend is compensated for that the two foot areas 5 and 9th next to each other at the same height.
- the both foot areas 5 and 9 bent identically and vertically shaped to the longitudinal direction of the metal strip so that the upper, into the socket 8 insertable area 7 of Sheet metal strip after soldering perpendicular to the circuit board 1 is aligned.
- the necessary to absorb the assembly forces The upper connector area 7 receives strength via the straight partial strip 13, while the against vibrations insensitive flexible connection 11 to the circuit board 1 is formed over the second partial strip 14.
- FIG. 4 shows a further embodiment of the plug 4 shown, which is similar to the embodiment of FIG 3. Below that which can be inserted into the socket 8, wide
- the upper area 7 is the sheet metal strip by two Slots 12a and 12b in three relatively narrow sub-strips 13, 14 and 16 divided as sheet metal strip extensions.
- On shorter partial strip 13 has the first at its end Foot area 5 for the first solder joint 6, while the two longer, flexible partial strips 14 and 16 on their Each ends a foot area 9 and 17 for the others Have solder connections.
- this connector can 4 thus at three different locations on a circuit board 1 be soldered on.
