Description
Technical Field
[0001] The present invention relates to an electrical connector according to claim 1, and a device having such an electrical connector and a circuit board. Background Art
[0002] Electrical connectors, for example in the form of electrical plug connectors, have many fields of application. Usually, the electrical conductors of the electrical connector are connected to the circuit board, for example, welded to the connection area of the circuit board. Here, the circuit board can be integrated into the electrical connector. In addition, the electrical connector can be configured, for example, in the form of a socket or an embedded plug and plugged into the circuit board and welded to it.
[0003] Electrical connectors should generally provide a good electrical connection that remains unchanged over a long period of time. In addition, electrical connectors should generally be simple to construct and manufacturable. Because electrical connectors are generally mass-produced products, simplification of structure and manufacture is generally particularly advantageous. Summary of the invention
[0004] An object of the present invention is to provide an electrical connector which can achieve reliable electrical connection with a structure as simple as possible.
[0005] This object is achieved by the subject matter having the features of claim 1 .
[0006] Therefore, an electrical connector is proposed, comprising: a body having an abutment surface, the body being attachable to a circuit board at the abutment surface; a first conductor having a first section and a second section; and a second conductor having a first section and a second section. It is provided that the first section of the first conductor and the first section of the second conductor extend spaced apart from each other, and the second section of the first conductor and the second section of the second conductor extend jointly from the body on the abutment surface adjacent to each other. The second sections extend in particular closer to each other than the first sections.
[0007] This allows two conductors to be connected together on the circuit board, in particular by means of a single soldering point. This enables a good electrical connection over a long period of time, has a simple structure and also allows a simplified connection, since likewise two connections can be connected at once by means of only one soldering point.
[0008] The second section of the first conductor and the second section of the second conductor jointly protrude from the body on the contact surface, for example, in such a way that they are in electrical contact or can be contacted with each other.
[0009] The second section of the first conductor and the second section of the second conductor extend, for example, parallel to one another. This allows for simple insertion, for example through an opening in a circuit board. In particular, the second sections abut one another.
[0010] Optionally, the second section of the first conductor at least partially surrounds the second section of the second conductor. The second section of the first conductor, for example, extends around at least a portion of the second section of the second conductor. This enables the two conductors to pass through a relatively small opening of the circuit board. In addition, the two conductors can support each other, which makes it easier for the conductors to pass through the opening without bending one of the two conductors.
[0011] The second sections of the conductors can, for example, contact each other along their length. The second section of the first conductor and the second section of the second conductor contact each other, for example, along a contact line or a contact area extending longitudinally. Thus, a particularly reliable electrical connection of the two conductors can be ensured. In addition, the two conductors can support each other well. Alternatively, there is a gap between the second sections, and then, for example, an electrical contact can be produced by means of soldering. The gap is, for example, smaller than the thickness of the second section of the first conductor and / or the second section of the second conductor.
[0012] Optionally, the second section of the second conductor (or the first conductor) extends coaxially with the first section of the second conductor (or the first conductor). This enables particularly simple production and arrangement of the conductor.
[0013] The second section of the second conductor extends, for example, offset from the first section of the second conductor. The two sections extend, for example, in mutually parallel directions. Alternatively or additionally, the second section of the first conductor extends offset from the first section of the first conductor.
[0014] In one embodiment, the first section of the first conductor has a sleeve shape.The first section of the first conductor optionally surrounds a further conductor (or surrounds a receptacle for the further conductor before mounting the further conductor).
[0015] The first section of the first conductor can provide, for example, shielding for a further conductor surrounded by the first section of the first conductor. This enables particularly good shielding that can be connected in a simple manner.
[0016] The second conductor can be configured in a pin-shaped manner, which simplifies the manufacture and design of the electrical connector.
[0017] The first conductor can be optionally made of (especially composed of) a flat material, for example by punching and bending a flat material block. The flat material can be placed on the second conductor, especially the pin-shaped conductor, in a space-saving manner and can also be easily formed into a sleeve.
[0018] The electrical connector can be constructed in the form of a plug connector. The electrical connector is, for example, an electrical plug connector. The electrical connector can have plug sections that can be electrically connected to a mating plug section of a mating plug connector by plugging.
[0019] According to one aspect, an electrical device is provided, comprising a circuit board and at least one electrical connector according to any one of the design solutions described herein. Advantages Refer to the above embodiments regarding the electrical connector.
[0020] The printed circuit board has, for example, an opening, for example in the form of a hole, wherein in particular the second section of the first conductor and the second section of the second conductor can be inserted jointly through the opening or are inserted jointly through the opening in the mounted state.
[0021] The second section of the first conductor and the second section of the second conductor can be soldered to each other in the assembled state, especially at the opening, for example, soldered to the edge area of the opening. Thus, a reliable electrical and mechanical connection between the two conductors and electrical contact on the circuit board are achieved.
[0022] Optionally, the second section of the first conductor and the second section of the second conductor are soldered to each other at the opening and are soldered or can be soldered to the circuit board. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Figure 1 An electrical connector 1 in the form of a plug connector is shown. The electrical connector 1 can be plug-connected with a matching counterpart plug connector 3 to establish an electrical connection. The electrical connector 1 forms a plug connection with the counterpart plug connector 3. The electrical connector 1 is configured as an embedded plug, for example.
[0035] The electrical connector 1 comprises a body 10 made of an insulating material, such as plastic, and preferably has a plurality of plug sections 13. The plug sections 13 can be connected to corresponding mating plug sections of a mating plug connector 3. An electrical conductor can be mounted on each plug section 13 and installed in the assembled state.
[0036] The body 10 of the electrical connector 1 has an abutment surface 100, at which the body 10 can be attached to the circuit board 2, for example Figure 2A and 2B shown.
[0037] The legs 103 on the contact surface 100 are used to make the electrical connector 1 stand on the circuit board 2 reliably and without shaking, and form a pressing part with the soldering part on the upper side of the circuit board. The positioning pins 101 on the abutment surface 100 are used to position the electrical connector 1 on the circuit board 2 in the correct orientation (see, for example, Figure 3 , 4 9). The body 10 has a base 102 which defines the abutment surface 100. The base 102 has a larger cross section than the rest of the body 10. This ensures that the electrical connector 1 is particularly reliable and firmly erected. The legs 103 are constructed on the base 102. The positioning pins 101 are constructed on the base 102.
[0038] The electrical connector 1 further comprises a first electrical conductor 11 and a second electrical conductor 12 (and optionally other electrical conductors). The first conductor 11 has a first section 110 and a second section 111. The second conductor 12 also has a first section 120 and a second section 121. It is provided that the first section 110 of the first conductor 11 and the first section 120 of the second conductor 12 extend spaced apart from each other, and the second section 111 of the first conductor 11 and the second section 121 of the second conductor 12 are directly adjacent to each other and are in electrical contact or contactable contact with each other and extend from the body 10 on the abutment surface 100 together. Here, the second sections 111 and 121 are in contact with each other. The second section 111 of the first conductor 11 and the second section 121 of the second conductor 12 are in contact with each other and protrude from the body 10 on the abutment surface 100 together.
[0039] The first section 110 and the second section 111 of the first conductor 11 are electrically connected to each other. The first conductor 11 is configured in one piece. The first section 120 and the second section 121 of the second conductor 12 are electrically connected to each other. The second conductor 12 is configured in one piece.
[0040] It should be noted here that the electrical connector 1 may also include more than two conductors 11, 12 arranged in this way. For example, a third conductor may be provided, which has a first section spaced apart from the other first sections 110, 120, and a second section in contact with the other second sections 111, 121. Alternatively or additionally, one or more additional pairs of first and second conductors may be provided, which are arranged as described above, respectively.
[0041] In particular, according to Figure 2A , 2B As can be seen from Figure 7, the second conductor 12 extends in a straight line (along a direction extending parallel to the insertion direction, along which the electrical connector and the mating plug-in connector can be inserted into each other). The second section 121 of the second conductor 12 is oriented coaxially with the first section 120 of the second conductor 12. The second conductor 12 is pin-shaped. The first section 120 of the second conductor 12 has one longitudinal end of the second conductor 12, and the second section 121 has the other longitudinal end of the second conductor 12. The end of the first section 120 of the second conductor forms a plug contact portion 122 for a corresponding mating plug contact portion of the mating plug-in connector 3. The end of the second section 121 of the second conductor 12 forms a solder foot for soldering to the circuit board 2. The second section 121 of the second conductor 12 protrudes so far from the abutment surface 100 that it passes through the opening 20 in the circuit board 2 in the assembled state (see, for example Figure 2A , 2B , 9 and 10). The opening 20 is here a hole or a plated-through hole in the printed circuit board.
[0042] The second conductor 12 provides, for example, a shielding contact. For example, the second conductor 12 is electrically connected to a shielding potential, a ground potential and / or a ground potential of the circuit board 2 in the assembled state.
[0043] The first section 110 of the first conductor 11 is designed in the form of a sleeve (see in particular Figure 7 and 8 ). The first section 110 of the first conductor 11 is oriented longitudinally and parallel to the second conductor 12. The first section 110 of the first conductor 11 is used as a shielding sleeve. The first section 110 of the first conductor 11, which is configured as a shielding sleeve, protects the two data contacts from the surrounding power contacts or external interference. For this purpose, the first section 110 of the first conductor 11 surrounds the two sockets of the electrical connector 1, in which one electrical conductor is arranged in each socket in the assembled state.
[0044] The second section 111 of the first conductor 11 is arranged offset from the first section 110 of the first conductor 11. The second section 111 of the first conductor 11 also extends parallel to the second conductor 12. The second section 111 of the first conductor 11 is arranged offset from the first section 110 of the first conductor 11 in a direction oriented perpendicularly to the first section 110 and the second section 111 of the first conductor 11. For this purpose, the first conductor 11 has an offset portion 112, which connects the first section 110 to the second section 111 in an electrically conductive manner. In addition, the first conductor has a tab opposite the offset portion 112, which is constructed in a mirror-image manner to the offset portion 112, but has an open end. In the assembled state, the first conductor 11 is supported on the body 10 by the offset portion 112 and the tab. The offset portion 112 transitions into the second section 111 of the first conductor 11.
[0045] In particular, Figure 8 The second section 111 of the first conductor 11 is shown to be flatly against the second section 121 of the second conductor 12. Specifically, the second section 111 of the first conductor 11 surrounds the second section 121 of the second conductor 12 over a portion of the circumference of the second conductor 12, as also shown in FIG. Fig.10 This configuration enables particularly good electrical contacting of the two conductors 11 , 12 and enables the two conductors 11 , 12 to be inserted together into a relatively small opening 20 of the printed circuit board 2 .
[0046] The first conductor 11 is made of a flat material, such as a metal sheet, specifically by punching and bending.
[0047] When manufacturing the electrical connector 1, the first conductor 11 is inserted into the opening of the body 10. The insert 14 is inserted into the first section 110 of the first conductor 11. Thus, the first conductor 11 is fixed to the body 10, wherein the offset portion 14 and the tab are locked between the body 10 and the insert 14, such as by Fig. 6A and 6B Visible offset 112 forms a step.
[0048] The insert 14 has two openings for each data contact and openings for the second sections 111, 121 of the first and second conductors 11, 12. In the body 10, further openings 104 (in particular four) are respectively used for data or power contacts, see e.g. Figure 3 and Figure 4 .
[0049] Especially according to Figure 1 , 4 As can be seen from Figure 5 , the second sections of the first conductor 11 and the second conductor 12 protrude perpendicularly above the contact surface 100 .
[0050] Fig. 9 and 10 A view of the bottom side of a circuit board 2 with an assembled electrical connector 1 is shown. The positioning pins 101 extend through the openings 21 of the circuit board 2, respectively. The second sections 110, 120 of the first conductor 11 and the second conductor 12 pass through the openings 20 of the circuit board 2 and can therefore be soldered to the corresponding electrical connection areas of the circuit board 2. Here, only a single soldering process is sufficient for the same two conductors 11, 12, which also reduces the work consumption for the connection. In addition, only one hole is required for the two conductors in the circuit board 2, and only one hole needs to be filled with paste if necessary, only one hole is required in the paste mask instead of two holes, etc. In addition, more layout area is provided on the circuit board 2. In addition, the connection area of the electrical connector 1 can be simplified. The solder reliably contacts the second sections 111, 121 electrically with each other. Therefore, the second sections 111, 121 provide contact areas. It is sufficient here that the second sections 111, 121 protrude closely from the abutment surface 100 to each other, because it is the solder that finally establishes the electrical connection.
[0051] A further advantage is that multiple potentials, such as ground potential, shielding potential and / or
[0052] or ground potential, is transmitted to the circuit board 2 at exactly one location.
[0053] This allows a space-saving arrangement with a simple and cost-effective structure. In addition, this common soldering is also particularly durable and resistant, unlike many electrical contacts that are established, for example, by spring forces and are usually more susceptible to aging and corrosion processes.
