Description

Connectors

The invention relates to a connector with a plug connector and a female connector, wherein the pin header comprises a plurality of contact pins which are spaced apart are disposed in at least one row within a contact carrier, and wherein the female connector socket contacts having at least two contact tongues.

Headers are often used in connectors for printed circuit boards. In the direction of the circuit boards of the contact carrier excellent contact pins are guided through the printed circuit boards and soldered on the underside thereof. Upward, the contact pins project freely out of the contact carrier, so that a female connector with female contacts can be placed as a mating connector for making contact.

The socket connector may be on the opposite side of the socket contacts in turn soldered to a printed circuit board, if two printed circuit boards are connected to each other through the connector. In alternative embodiments, the female connector may comprise insulation-displacement contacts for making contact with a flat ribbon cable. Furthermore, for example, from document US 6,146,181 A, an embodiment of the female connector as Schraubkontaktblock known in which the socket contacts are connected with screw or are integrated therein, wherein a cable connection through the screw contacts takes place.

The contact pins of such a pin header can be arranged in one or more parallel rows. In particular, when a larger number of contact pins in one or more rows is present, the attaching of a female connector may require on the pin header high insertion forces. In egg nem manual placement of the socket connector onto the pin strip there is a danger to bend due to uncontrolled use of force, the contact pins of the plug connector or the tongues of the socket connector.

It is therefore an object of the present invention to provide a connector with a plug connector and a female connector, wherein at equal contact forces a lower insertion force for fitting the female connector is required on the plug connector and in which the risk of the contact pins and / or the contact tongues is reduced to bend or expand in an uncontrolled manner. This object is achieved by a connector having the features of the independent claim. Advantageous embodiments and further developments are subject of the dependent claims. An inventive connector of the aforementioned type is characterized in that a first and a second group of contact pins is provided in the pin header, whereby the contact pins of the first group on a contact side of the pin strip protrude further from the contact carrier than the contact pins of the second group, and that are provided in the carrying bar stops which limit a spring movement of the contact tongues.

By the contact page to which the female connector is fitted, to different extents protruding pins contact while placing the female connector, first the longer contact pins of the first group the socket contacts of the female connector. So the side, Accordingly, these female contacts are widened by the contact pins of the first group during the further fitting the female connector first. The necessary forces are lower than for pin strips according to the prior art, in which all the contact pins protrude the same distance, which must be expanded all female contacts simultaneously.

On further plugging in the plug connector then the contact pins of the second group come into engagement with the respective socket contacts and wide to this, while the contact pins of the first group can penetrate into the corresponding socket contacts already without major force requirement on. The distance through which the increased insertion forces are applied during expansion of the female contacts is extended thereby, however, the maximum required insertion force is reduced, whereby the risk of damage is reduced by high poorly be controlled insertion forces.

In addition, it is ensured by the stops for the contact tongues in the socket contacts, that the contact tongues can not be moved beyond a certain predetermined clearance between the respective stop and the respective contact tongue outwards. This prevents possibly obliquely inserted contact pins may bend the contact tongues of the socket contact so far that they are plastically deformed and then applying a lower contact force on the contact pins used. In an advantageous embodiment of the connector pins of the first and second group are alternately disposed within the at least one row. In this way, the required insertion forces evenly as possible over the length of the header.

In a further advantageous embodiment of the plug connector at least two, preferably parallel rows of contact pins are provided. Here, in each of the rows both contact pins of the first and the second group is present. In this way, even for the different tire the pin strip hen equal as possible achieved, so that an occurrence of a tilting moment when plugging the plug connector is prevented large insertion forces.

In a further advantageous embodiment of the connector, the contact pins of the pin connector have at their free end a section which run inclined side surfaces. The first group of contact pins stands out by a length relative to the contact pins of the second group corresponding to at least the length of the portion with the inclined side surfaces. The tapered end pins facilitate the expansion of the socket contacts. Characterized in that the lengths of the various contact pins by at least reached the length of time is different tapered portion, that the socket contacts associated with the contact pins of the second group, are only expanded when the socket contacts of the contact pins is assigned to the first group, have already been substantially completely expanded.

In a further advantageous embodiment of the plug connector, the socket connector is constructed as a contact block, the screw terminals for connection to connection cables, wherein the screw terminals are connected to socket contacts of the female connector.

In a further advantageous embodiment of the connector, the stops are arranged laterally next to the contact tongues of the socket connector. each of the contact tongues of a socket contact are preferably excluded forms together with the associated stops integrally formed of a contact plate. The stops may be so shaped without any additional assembly costs in producing the Buchsenkontaks in a punching and bending process. The invention is described using an exemplary embodiment explained in more detail by means of figures. The figures show:

Figure 1 is an isometric view of a connector having plug connector and socket connector in an unmated state.

2 shows the connector from Fig 1 in an assembled state..;

Fig. 3 is an isometric exploded view of the socket connector according to

Fig. 1 and Fig. 2; and

Fig. 4 is a contact insert of the socket connector of Figure 3 in two different representations.:

Fig. 1 shows in a schematic isometric view of a connector with a plug connector 10 and a female connector 20 in an unmated state. Fig. 2 shows the connector in an assembled state.

The pin connector 10 comprises a contact support 1 1, which is preferably integrally made of a plastic in an injection molding process. In the present case the contact carrier 1 1 is configured U-shaped, the upstanding leg of the U-shaped contact carrier are carried out 1 1 of different lengths. The U-shaped configuration of the contact carrier 1 1 serves to guide the female connector 20 when inserting and also prevents acting on the female connector 20 forces of contact pins 15, 1 6 of the pin bar 10 or socket contacts of the female connector 20 must be included.

On an underside of the contact carrier 1 1 webs 12 are formed with which the contact carrier 1 1 can for example be placed on the surface of a printed circuit board.

In the front in Fig. 1 leg of the contact carrier 1 1 is a positioning notch 13 is arranged, which serves a correct positioning of the patch connector strip 20. On the female connector 20, a protrusion 23 is formed for this purpose, which engages in the assembled state of the connector in the positioning notch. 13 At the rear legs of the contact carrier 1, 1 is a locking lug 14 is provided, the crack 24 of the female connector 20 engages behind a Gehäusevor- and accidental loosening of the female connector 20 of the plug connector 10 is prevented.

The pin header 1 0 includes in the embodiment shown the contact pins 1 5, 1 6 which are present spaced from one another in a row. The contact pins 15, 1 6 are preferably encapsulated by the material of the contact support 1 1 and is secured in this manner in the contact support 1. 1 is shown in FIG. 1, not visible, that the contact pins 1 5, protrude 1 6 downward via the webs 1 2 so that they insulation piercing a printed circuit board through corresponding bores gene can and can be soldered to printed conductors of the printed circuit board.

Upwards, ie in the direction of the to-install female connector 20, protrude beyond the contact pins 15, 1 6 freely with a contact portion of the contact carrier 1 1 out. there are registration According to two different groups of con- tact donate 1 5, 1 6 provided: Continue from the contact carrier 1 1 outstanding contact pins 15 and 6 less far out of the contact carrier 1 1 outstanding pins 1 ease of illustration these against the contact pins 15 are of first group below as long pins 1 and 5, the contact pins as short pins 1 6 1 6 draws loading the second group.

In the example illustrated in Figures 1 and 2 embodiment, long pins 1 and 5 short pins 1 6 alternate in the row of the contact pins 15, 1. 6 This ensures that the length of the pin header 10, that is in a direction along the row of pins 1 5, 1 6, act as uniform as possible insertion forces. Alternatively to the illustrated embodiment, the contact pins 1 5, 1 6 may also be arranged in several, then preferably mutually parallel rows. In the case of long pins 1 5 is advantageous, as well as short pins 1 6 provided within each of the rows to obtain also in a direction transverse to the longitudinal extent of the rows as uniform as possible insertion forces, which prevent the occurrence of the breakdown torque during insertion of the female connector 20th

As can be seen in Fig. 1, the contact pins 1 5, 1 6 is provided at its upper free end with sloping sides so that the slightly tapered are. This shape facilitates the insertion of the contact pins 1 5, 1 6 in the corresponding socket contacts. The difference in the length of protruding from the contact carrier 1 1 contact portions of the contact pins 1 5, 1 6 is preferably at least as great as the length of the tapered portion of the contact pins 15, 1 6. This ensures that the assigned to the longer pins 15 socket contacts are fully expanded when the shorter pins 1 6 expand their associated socket contacts. In this way, the pin header 1 0 necessary for plugging the female connector 20 mating forces are optimally distributed over the entire insertion path.

In the illustrated embodiment, two groups of different length contact pins 15, 1 6 are formed. It is possible in alternative embodiments to use more than two groups, for example, three groups of contact pins each having a different length.

The socket connector 20 shown in Figs. 1 and 2 is formed as a contact block with screw in this embodiment. In the socket connector not visible female contacts are formed in these figures, the pins 1 5, 1 6 are associated and in each case with one of these contact pins 15 contact 1 6 when the female connector is fitted 20 to the pin header 1 0th Each socket contact is connected to a screw terminal, to subse- a connecting cable to the corresponding female contact to SEN.

The number of seven contact pins 5 1 shown in this example, 1 6 and corresponding seven female contacts is purely exemplary. According to the application pin connector 10 may include more or less than the seven illustrated con- clock pins. The achieved reduction of the insertion force is particularly advantageous in strips with a large number of contact pins.

The female connector 20 includes a two-part housing consisting of a housing body 21 and an attached from the front of this housing cover 22nd In the front housing cover openings are provided for insertion of said connecting cable. In the housing body 21 of each of the openings is associated with a compartment 25 (see FIG 3. Fig.) Is formed, having a contact insert more fully described below, 30 (see. Fig. 3 and 4) receives. Holes are provided for screws 35 of the contact insert 30 at an upper side of the housing body 21, with which the connection cable can be screwed into the corresponding contact inserts 30th

Fig. 3 shows the female connector 20 according to Figures 1 and 2 in an exploded view. In this representation, the arrangement of the inserts 30 within the female connector 20 is visible. The individual inserts 30 each have a contact cage 31, preferably a one-piece injection-molded part, the screw already mentioned is screwed 35 into the top. From the front housing cover 22 of the female connector 20 side opposite from a three-dimensionally shaped contact plate is inserted in the contact cage 31 32 as the actual contact material. The contact plate 32 is preferably manufactured in one piece in a punching and bending process. On the contact plate 32 of the socket contact 33 is formed facing downward. 34 at the top projecting a contact tab into the contact cage 31st pulled by the screw 35 against the contact tab 34 of the contact cage 31, wherein an inserted wire connection between this contact cage 31 and the contact lug is clamped 34 and thus contacted through the contact tab 34 of the socket contact 33rd

Fig. 4 shows the contact insert 30 with inserted contact plate 33 in more detail in two different representations, left isometric and right in a plan view of the socket contact 33. In FIG. 4, in particular the configuration of the socket contact 33 with two each other is seen to curved contact tongues. Stops 36 also are formed from the material of the contact plate 32nd The stops 36 are positioned laterally next to the contact tongues of the socket contact 33, thereby limiting an expansion of the socket contact 33rd The contact tongues of the socket contact 33 thus can not be moved over a certain predetermined clearance between the respective stop 36 and the respective contact tongue outwards. This prevents obliquely inserted contact pins 1 5, 1 6, the contact studs of the socket contact 33 can bend so much that it will be plastically deformed and subsequently a lower contact force on the contact pins used 1 5, 1 apply. 6 Reference numeral pin header
