Description

[Technical field]

[0001] The invention relates to an electrical connector according to claim 1 and to an assembly comprising such an electrical connector and a printed circuit board. [Background technology]

[0002] Electrical connectors, for example in the form of electrical plug connector parts, have a wide range of applications. Often, the electrical conductors of the electrical connector are connected to a printed circuit board, for example by soldering to a connection area of ​​the printed circuit board. The printed circuit board can be integrated into the electrical connector. Furthermore, the electrical connector can be designed in the form of a socket or a built-in plug, etc., which can be plugged into and soldered to the printed circuit board.

[0003] Electrical connectors should consistently provide a good electrical connection over time. Additionally, electrical connectors should generally be simple to design and manufacture. Because electrical connectors are often mass-produced products, simplicity in design and manufacture is often especially important. Summary of the Invention [Problem to be solved by the invention]

[0004] SUMMARY OF THE PRESENT EMBODIMENT It is an object of the present invention to provide an electrical connector which provides a secure electrical connection with as simple a design as possible. [Means for solving the problem]

[0005] This object is achieved by an article having the features of claim 1.

[0006] Thus, an electrical connector is provided that includes a body having a contact side that can be placed against a printed circuit board, a first conductor with a first section and a second section, and a second conductor with 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 at a distance from each other, and the second section of the first conductor and the second section of the second conductor protrude together from the body at the contact side adjacent to each other. In particular, the second sections are closer to each other than the first sections.

[0007] This specifically allows both conductors to be connected together to the printed circuit board using a single solder point, which allows for a good electrical connection over time with a simple design, and also allows for a simplified connection since two connections can be made at once with only one solder point.

[0008] The second section of the first conductor and the second section of the second conductor are, for example, in electrical contact or contactable and protrude together from the body on the contact side.

[0009] For example, the second section of the first conductor and the second section of the second conductor may extend parallel to one another, which may facilitate threading through an opening in, for example, a printed circuit board. Specifically, the second sections are adjacent to one another.

[0010] Optionally, the second section of the first conductor surrounds the second section of the second conductor in at least some area. For example, the second section of the first conductor extends around at least a portion of the second section of the second conductor. This allows both conductors to be guided through a relatively small opening in the printed circuit board. Furthermore, the two conductors can support each other, facilitating the two conductors to be guided through the opening without either conductor bending.

[0011] The second sections of the conductors may touch each other, for example along their length. The second section of the first conductor and the second section of the second conductor are in contact with each other, for example along a contact line or an elongated contact area. This ensures a particularly solid electrical connection between the two conductors. The two conductors can also thereby be well supported by each other. Alternatively, there may be a gap between the second sections, so that the electrical contact is made, for example by soldering. The gap is for example smaller than the thickness of the second section of the first conductor and / or the second conductor.

[0012] Optionally, the second section of the second conductor (or the first conductor) is coaxial with the first section of the second conductor (or the first conductor), which allows for a particularly simple manufacture and assembly of this conductor.

[0013] For example, the second section of the second conductor is offset from the first section of the second conductor, both sections extending along a direction parallel to each other. Alternatively or additionally, the second section of the first conductor is offset from the first section of the first conductor.

[0014] In one embodiment, the first section of the first conductor is sleeve-shaped, optionally surrounding another conductor (or a socket for the additional conductor prior to installation of the additional conductor).

[0015] The first section of the first conductor can provide shielding, for example for other conductors that are surrounded by the first section of the first conductor. This allows for particularly good shielding, which can be connected in a simple manner.

[0016] The second conductor may be pin-shaped, which allows the electrical connector to be easily manufactured and designed.

[0017] The first conductor is optionally made of (particularly consisting of) a flat material, for example by punching and bending a piece of flat material, which can be placed in a space-saving manner adjacent to the second conductor, which is particularly pin-shaped, and can also be easily formed into a sleeve.

[0018] The electrical connector may be designed in the form of a plug connector part, so that the electrical connector is, for example, an electrical plug connector part, and may have a plug area which can be electrically connected to a mating plug area of ​​a mating plug connector part.

[0019] According to one aspect, there is provided an electrical assembly comprising a circuit board and at least one electrical connector according to any embodiment described herein. With regard to advantages, reference is made to what has been stated above with regard to the electrical connector.

[0020] The printed circuit board has an opening, for example in the form of a hole, and in particular the second section of the first conductor and the second section of the second conductor can be inserted together or in an assembled state through the opening.

[0021] The second section of the first conductor and the second section of the second conductor can be soldered together in the assembled state in the opening, in particular in the edge region of the opening, thereby allowing a firm electrical and mechanical connection between both conductors and an electrical contact at the printed circuit board.

[0022] Optionally, the second section of the first conductor and the second section of the second conductor are soldered together in the opening and soldered to the printed circuit board or can be soldered to the printed circuit board.

[0023] The idea forming the basis of the invention is explained in more detail below using an exemplary embodiment shown in the drawings. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0025] 1 shows an electrical connector 1 in the form of a plug connector part. The electrical connector 1 can be plugged into a suitable mating plug connector part 3 in order to establish an electrical connection. The electrical connector 1 forms a plug connection with the mating plug connector part 3. The electrical connector 1 is designed, for example, as a built-in plug.

[0026] The electrical connector 1 comprises a body 10 made from an insulating material, such as plastic, and preferably has a plurality of receptacle sections 13. Each of the receptacle sections 13 can be connected to a corresponding mating receptacle section of a mating plug connector part 3. Electrical conductors can be mounted in each of the receptacle sections 13 and are mounted in the assembled state.

[0027] The body 10 of the electrical connector 1 has a contact side 100 at which the body 10 can be placed against a printed circuit board 2, as shown, for example, in Figures 2A and 2B.

[0028] The legs 103 on the contact side 100 serve to ensure a firm and wobble-free position of the electrical connector 1 on the printed circuit board 2 and form a distance to the formation of solder points on the upper side of the printed circuit board. The locating pins 101 on the contact side 100 serve to position the electrical connector 1 in the correct orientation on the printed circuit board 2 (see, for example, Figures 3, 4 and 9). The body 10 has a base 102 which defines the contact side 100. The base 102 has a large cross section compared to the remainder of the body 10. This ensures a particularly firm and robust position of the electrical connector 1. The legs 103 are formed on the base 102. The locating pins 101 are formed on the base 102.

[0029] The electrical connector 1 further comprises a first conductor 11 and a second conductor 12 (optionally comprising further 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 at a distance from each other and that the second section 111 of the first conductor 11 and the second section 121 of the second conductor 12 are in electrical contact with each other or can be in contact with each other and protrude together from the body 10 at the contact side 100 directly adjacent to each other. In this case, the second sections 111, 121 touch each other. The second section 111 of the first conductor 11 and the second section 121 of the second conductor 12 touch each other and protrude together from the body 10 at the contact side 100 .

[0030] 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 formed as a single 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 formed as a single piece.

[0031] In this regard, it should be noted that the electrical connector 1 may comprise more than the two conductors 11, 12 arranged in this manner. For example, a third conductor may be provided with 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 further pairs of first and second conductors may be provided, each arranged as previously described.

[0032] As can be seen in particular from Figures 2A, 2B and 7, the second conductor 12 extends in a straight line (along a direction extending parallel to an insertion direction in which the electrical connector and the mating plug connector part can be plugged into each other). The second section 121 of the second conductor 12 is aligned 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 comprises one longitudinal end of the second conductor 12, and the second section 121 comprises the other longitudinal end of the second conductor 12. The end of the first section 120 of the second conductor forms a plug contact 122 for a corresponding mating plug contact of the mating plug connector part 3. The end of the second section 121 of the second conductor 12 forms a solder pin for soldering to the printed circuit board 2. The second section 121 of the second conductor 12 protrudes far enough from the contact side 100 to extend, in the assembled state, through an opening 20 in the printed circuit board 2 (see, e.g., Figures 2A, 2B, 9, and 10). The opening 20 is a hole or through-hole in the printed circuit board.

[0033] The second conductor 12 represents for example a contact of a shield, for example the second conductor 12 being electrically connected in the assembled state to a shield, earth and / or to the ground potential of the printed circuit board 2.

[0034] The first section 110 of the first conductor 11 is sleeve-shaped (see in particular Figs. 7 and 8). The first section 110 of the first conductor 11 is elongated and aligned parallel to the second conductor 12. The first section 110 of the first conductor 11 serves as a shielding sleeve. The first section 110 of the first conductor 11 designed as a shielding sleeve protects the two data contacts from interference from surrounding power contacts or from external interference. For this purpose, the first section 110 of the first conductor 11 surrounds two plug openings of the electrical connector 1 in which the conductors are placed in the assembled state.

[0035] The second section 111 of the first conductor 11 is 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 offset from the first section 110 of the first conductor 11 in a direction perpendicular to the orientation of the first section 110 and the second section 111 of the first conductor 11. For this purpose, the first conductor 11 has an offset 112 that conductively connects the first section 110 to the second section 111. The first conductor also has a tab opposite the offset 112 that is mirrored to the offset 112, but has an open end. In the assembled state, the first conductor 11 is supported by the offset 112 and by a tab on the body 10. The offset 112 merges into a second section 111 of the first conductor 11 .

[0036] 8 shows that the second section 111 of the first conductor 11 borders and completely follows 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 can also be seen in FIG. 10. This configuration allows for a particularly good electrical contact between the two conductors 11, 12 and allows for insertion of the two conductors 11, 12 into a relatively small opening 20 in the printed circuit board 2 at the coupling.

[0037] The first conductor 11 is made from a flat material such as a metal sheet, specifically by punching and bending.

[0038] During manufacture of the electrical connector 1, the first conductor 11 is inserted into an opening in the body 10. The insert 14 is inserted into a first section 110 of the first conductor 11. As a result, the first conductor 11 is fixed to the body 10 and the offset 112 and the tab are locked between the body 10 and the insert 14, as can be seen specifically from Figures 6A and 6B. The offset 112 forms a step.

[0039] The insert 14 has two openings, one for each data contact and one opening for the second area 111 of the first conductor 11 and the second area 121 of the second conductor 12. In the body 10, for example, looking at Figures 3 and 4, there are further openings 104 (specifically four) for each data or power contact.

[0040] In particular, it can be seen from FIGS. 1, 4 and 5 that the second sections of the first conductor 11 and the second conductor 12 protrude vertically from the contact side 100 .

[0041] 9 and 10 show views of the underside of the printed circuit board 2 with the electrical connector 1 mounted thereon. The locating pins 101 extend through the openings 21 of the printed circuit board 2, respectively. The second areas 110 of the first conductors 11 and the second areas 120 of the second conductors 12 pass through the openings 20 of the printed circuit board 2 and can thereby be soldered to the corresponding electrical connection areas of the printed circuit board 2. In this case, only a single soldering process is sufficient for both conductors 11, 12, which also reduces the work required for the connection. Also, only one hole is required for both conductors in the printed circuit board 2, and if necessary, one hole needs to be filled with paste, instead of two holes only one hole is required in the paste mask, etc. Furthermore, a larger layout space is available in the printed circuit board 2. Also, the connection area of ​​the electrical connector 1 can be simplified. The solder brings the second areas 111, 121 into firm electrical contact with each other. The second areas 111, 121 therefore provide contact zones. It is sufficient for the second areas 111, 121 to protrude from the contact side 100 close to each other in order for the solder to establish an electrical connection at the latest.

[0042] A further advantage is that multiple potentials, such as ground, shield and / or earth potentials, are brought to the printed circuit board 2 in just one location.

[0043] This allows for a space-saving assembly with a simple and cost-effective design, and the solder of such a connection is particularly stable and resistant in the long term, in contrast to many electrical contacts, for example made by spring force, which are generally more susceptible to degradation and corrosion processes.
