Description

1287329 IX. Description of the invention: [Technical field to which the invention pertains] According to the preamble of claim 1, the present invention relates to a plug-in connector for a printed circuit board. [Prior Art] DE 199 45 412 A1 and DE 102 57 308 B3 respectively disclose a plug-in connector for a brush circuit board comprising: a plurality of contact elements each having two connection sides, one of which is connected The side surface is formed as a contact for connecting the puncture insulator of the wire, and the other connection surface is formed as a bifurcation and a plastic case for contacting the terminal area on a printed circuit board, wherein the contact of the puncture insulator And the contacts are arranged to rotate relative to each other, and at least a lower edge of the joint of the piercing insulator is supported on the plastic casing such that when a connection force occurs at the junction of the piercing insulator The contact elements are restrainedly held in the plastic housing. In each case, the Laiwu plastic broke is formed in two parts, the contact element is first pushed into the first part of the outer casing, and then the second part of the outer casing is latched in the first part of the outer casing. A disadvantage of the plug-in connection benefits of known printed circuit boards is that they are relatively complicated to manufacture. SUMMARY OF THE INVENTION The present invention is therefore based on the technical problem of providing a plug-in connector for use: "The solution to this technical problem of manufacturing a printed circuit board is provided by an application. The advantageous part of the main body is advantageous. The refinement of the content is made by the accessory for this purpose, and the plastic part is formed as a single piece... - the part of each of the forked joints 106096.doc 1287329 is at least partially formed in an elastic form. This achieves the following effects: when the contact element is mounted When the plastic case is provided, the case can be smeared to introduce the contact element and then elastically cut back again. The contact element can be read and fixed. The production of the input connector requires the installation of another plastic. In a preferred embodiment, between the junction of the puncture insulator and the junction

In the transition region, the contact element is formed with two interrogation elements which are locked into the latching capacity φ of the plastic housing. In the case of the Α, 降, ατ, the latch containers are further formed into the slits in the outer casing walls. In another preferred embodiment, the sub-contacts are completely received by the outer casing in the longitudinal direction. In this case, the other groove or guide (at least the guide point and the contact point) preferably forms the wall of the casing and the actual contact area of the contact point protrudes beyond the groove or guide. In another preferred embodiment, the plastic outer casing is formed to be at least on the side wall

The one-piece version of the plastic housing helps simplify insertion and requires only one injection mold. In addition, the shell 0 is not split. - Aspect, this achieves the elasticity of need. Alternatively, the split form also enables the plug-in connector to be mounted to a wider printed circuit board. In another preferred embodiment, the contact and the contact point of the puncture insulator are replaced by Make it at 45. Rotate relative to the other party within the range. For the connection operation, the 'insulator piercing joint is at about 45. The arrangement of the contact elements at the angle is advantageous, and in addition, when the contact elements are formed in one piece as a stamping or bending member, an edge which can be used as a support is necessarily formed. In the other - better implementation of the puncture insulation joints and points and junctions 106096.doc 1287329 in a common center ♦ by μ L, ^, . The advantage of this embodiment is that the connecting force occurring at the joint of the puncture insulator does not produce a bending moment or produces an inconspicuous bending moment. In addition, the vertical plug-in connector can be made narrower and the number of contact elements is the same.

In another preferred embodiment, the plug-in connector is released from the side of the jaw by the latch spring by means of the latch spring. This type of latching spring is described in DE 丨❹1"1 449 A1, which is used for the adaptation of the fiber-optic plug-in connector. A reference to the statement relating to the lock. [Embodiment] The plug-in connector of Fig. 1 is shown in a side view. The plug-in connector 1匕3 single-component plastic case 2. In the upper region, the plastic outer casing 2 is formed with a clamping rib 3, and the joint u of the puncture insulator of the contact member 1 is arranged between the ribs (see Fig. 4). Arranged below the clamp ribs 3, on the outer wall of the casing is a wire guide 5. In the lower region of the plastic casing 2 in which the contact element 10 is located, the outer casing 2 has a latching container 6 formed as a rectangular slit. Between each pair of latch containers 6, the outer casing wall 4 has a recessed recess 7 therein. In addition, the outer casing wall 4 has two containers 8' on the sides for a locking mechanism (not shown) by means of which the male connector 1 is fastened to, for example, a metal il frame. On the inside, the outer casing wall 4 is formed with grooves 9 in which the branch joints 12 are guided via its side surfaces 13. In this case the actual contact area 14 of the furcation joint 12 is curved inwardly and protrudes beyond the groove 9. In the transition region between the bifurcated joint 12 and the joint 11 of the piercing insulator, the contact element 106096.doc 1287329

The piece 10 has two locking pins 15, which are latched into the latching receptacle 6, as can be seen in Figures 3 or 4. It is also seen in Figure 3 that the puncture insulator joint 11 and the bifurcated joint 12 are on a common central axis 16. Furthermore, it can be seen in Figure 3 how the locking pin 15 is supported in the plastic housing 2 in a downward direction on the bearing surface 20. These load bearing surfaces 20 absorb the connection forces that occur during the wiring process of the contact of the puncture insulator. In addition, the plastic housing has stop surfaces 21 and 22 against which the contact elements 1 碰 contact the edges 17 and 18. The side walls 23 of the plastic outer casing 2 also have a slot 24 in the region of the split joint 12, respectively. Due to the groove 24, the two outer casing walls 4 can be flexibly opened relative to each other, so that the contact member 10 can be pushed into the plastic outer casing 2 from below together with the locking pin 15 until the locking pin 15 is latched into the latch container 6 .
