Hereinafter, a connector device according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings.
The device 1 is a connector device used for so-called board-to-board connection. First, a horizontal connection type first embodiment will be described.

  The connector device 1 includes a pair of a header (“first connector” in the claims) 10 and a receptacle (“second connector” in the claims) 20 that can be fitted to each other. The top perspective view, front view, and bottom view of the header 10, FIGS. 4 to 6 are the top perspective view, front view, and bottom view of the receptacle 20, and FIG. 7 shows the fitting state of the header 10 and the receptacle 20. The header 10 and the receptacle 20 are suspended from the horizontal substrates 2 and 2 ', respectively, and the suspended header 10 and the receptacle 20 are disposed in a horizontal direction on the substrate 2 and the substrate 2'. The header 10 and the receptacle 20 can be fitted to each other in the longitudinal direction (direction perpendicular to the fitting direction of the header 10 and the receptacle 20). A shape.

  The header 10 has a generally elongated housing 51, two types of signal terminals 31A and 31B arranged and fixed near the center of the housing 51, and two types arranged and fixed at both ends of the housing 51. The first functional terminal 11A and the second functional terminal 11B are provided. Similarly, the receptacle 20 as a whole has a substantially elongated housing 61, two types of signal terminals 41A and 41B that are disposed and fixed near the center of the housing 61, and both ends of the housing 61. Two types of fixed first function terminals 21A and second function terminals 21B are provided. As will be described below, each functional terminal (multifunction bracket) 11A, 11B, 21A, 21B provided on the header 10 or the receptacle 20 functions as, for example, a ground terminal, a power supply terminal, or a detection terminal. To get. The user can freely design which terminal functions.

  The housing 51 of the header 10 has a fitting protrusion 53 that protrudes to the fitting side of the header 10 and the receptacle 20. An insertion space 54 in which an insertion port 55 is provided on the protruding side is formed inside the fitting protruding portion 53.

  The housing 61 of the receptacle 20 includes an insertion hole 63 and a terminal array portion (“inserted portion” in the claims) 64 provided inside the insertion hole 63. When the header 10 and the receptacle 20 are fitted to each other, the fitting protrusion 53 of the header 10 is inserted into the insertion hole 63 in the fitting direction of the header 10 and the receptacle 20. The terminal arrangement portion 64 protrudes to the fitting side of the header 10 and the receptacle 20, and is fitted through the insertion port 55 into the insertion space 54 of the fitting protrusion 53 provided on the header 10 side when the header 10 and the receptacle 20 are fitted. Inserted in the direction. The depth of fitting can be determined by the position where the front outer wall 76 of the header 10 and the front outer wall 66 of the receptacle 20 collide.

  The signal terminal 31A and the signal terminal 31B are formed of a substantially flat metal plate as a whole. The signal terminals 31 </ b> A and 31 </ b> B are fixed by press-fitting from the rear of the housing 51. For example, a bellows terminal can be used as a signal terminal. When a bellows terminal is used, the reliability of contact can be improved and a smooth fitting feel can be obtained. The terminal contact portion 33A provided at the tip of the signal terminal 31A is a portion other than both longitudinal ends of the header 10 where the functional terminals 11A and 11B are arranged, for example, the upper central inner wall excluding both ends of the fitting protrusion 53, and The terminal contact portion 33B provided at the tip of the signal terminal 31B is arranged and fixed in parallel along the longitudinal direction of the header 10, for example, on the lower center inner wall excluding both ends of the fitting protrusion 53. The terminal contact portions 33A and 33B of the signal terminals 31A and 31B are exposed in the insertion space 54 in order to make contact with the signal terminals 41A and 41B of the receptacle 20 when the header 10 and the receptacle 20 are fitted. Further, since the tips 33A and 33B are isolated from each other, the crosstalk can be effectively reduced.

  The signal terminal 41A and the signal terminal 41B are also formed of a substantially flat metal plate as a whole. The signal terminals 41A and 41B can also be fixed by press-fitting from the rear of the housing 61. For example, a bellows terminal can be used. The terminal contact portion 43A provided at the tip of the signal terminal 41A is a portion other than both longitudinal ends of the receptacle 20 where the functional terminals 21A and 21B are disposed, for example, inside the upper center excluding both ends of the terminal arrangement portion 64, and The terminal contact portion 43B provided at the tip of the signal terminal 41B is arranged and fixed in parallel along the longitudinal direction of the receptacle 20, for example, inside the lower stage center excluding both ends of the terminal arrangement portion 64. Since the terminal contact portions 43A and 43B of the signal terminals 41A and 41B are brought into contact with the terminal contact portions 33A and 33B of the signal terminals 31A and 31B of the header 10 when the header 10 and the receptacle 20 are fitted, the terminal arrangement portion 64 is provided. At least a part of the insertion hole 63 provided in the periphery is exposed. Further, since the tips 43A and 43B are isolated from each other, the crosstalk is effectively reduced.

  In the header 10 and the receptacle 20, the arrangement of the signal terminals 31A, 31B, 41A, 41B is suitable for high-speed signal transmission. For example, the group of signal terminals 31A and the group of signal terminals 31B arranged in parallel are respectively in the longitudinal direction of the header 10, and the group of signal terminals 41A and the group of signal terminals 41B arranged in parallel are respectively receptacles. In the longitudinal direction of 20, the contact pitches are optimally arranged for impedance matching. As is well known, as the pitch becomes narrower, the impedance becomes lower, so it is preferable to set the pitch as narrow as possible. Further, in each group of the signal terminal 31A group, the signal terminal 31B group, the signal terminal 41A group, and the signal terminal 41B group arranged in parallel, two adjacent signal terminals are adjacent differential pairs. Further, the signal terminal located between these adjacent differential pairs is made to function as a ground, thereby reducing crosstalk.

  When the header 10 and the receptacle 20 are fitted, the substrate 2 and the substrate 2 ′ are contacted between the signal terminal 31A and the signal terminal 41A, between the signal terminal 31B and the signal terminal 41B, and between these terminal contact portions. Signal transmission takes place between them. At the time of contact between these terminal contact portions, the separation distance a in the horizontal direction between the signal terminal 31A and the signal terminal 31B on the header 10 side is the separation distance a ′ in the horizontal direction between the signal terminal 41A on the receptacle 20 side and the signal terminal 41B. In the horizontal direction, the signal terminal 31A and the signal terminal 31B on the header 10 side, and the signal terminal 41A and the signal terminal 41B on the receptacle 20 side are substantially linear in the horizontal direction. By adopting such a configuration, generation of noise such as crosstalk can be suppressed as much as possible. At this time, the maximum gap length b 'formed between the signal terminal 31A and the signal terminal 41A is smaller than the thickness b' of the signal terminal 41A. With such a configuration, the distance between the signal terminal 31A on the header 10 side and the signal terminal 41A on the receptacle 20 side can be reduced, and the bending of the signal terminal 41A can be reduced as much as possible. It can be improved, and a relatively long effective contact length c can be secured.

Embedded in a fixed state. As described above, the fixed contact portion 25B is embedded in the lateral outer wall 79 of the terminal arrangement portion 64 and the elastic contact portion 25A extends along the inner side of the lateral outer wall 67 of the housing 61. Therefore, there is little risk that the fixed contact portion 25B and the elastic contact portion 25A are damaged due to a twisting or the like during fitting. The elastic contact portion 25A is in contact with the fixed contact portion 15A of the header 10 when the header 10 and the receptacle 20 are fitted, and can be displaced in a direction away from the first functional terminal 11A of the header 10 through this contact. A space 57 is provided in the lateral inner wall 65 of the insertion hole 63 in order to displace the elastic contact portion 25A in this way.

  In this configuration, the degree of protrusion of the first functional terminal 11A, the second functional terminal 11B, the signal terminal 31A, or the signal terminal 31B of the header 10 on the fitting side (receptacle 20 side), or the first of the receptacle 20 By adjusting the degree of protrusion of the function terminal 21A, the second function terminal 21B, the signal terminal 41A, or the signal terminal 41B on the fitting side (header 10 side), the contact timing can be set appropriately. Further, by appropriately setting the function of each terminal, the contact between the first function terminal 11A and the first function terminal 21A and the second function terminal 11B and the second function terminal 21B when the header 10 and the receptacle 20 are fitted. The contact between the signal terminal 31A and the signal terminal 41A and the contact between the signal terminal 31B and the signal terminal 41B can be freely designed.

  One design example will be described with reference to FIGS. Each of FIGS. 9 to 11 is a diagram showing a process until one contact is completed divided into three contact timings. (A) of each figure is a figure which shows the contact timing of signal terminal 31A and signal terminal 41A, and signal terminal 31B and signal terminal 41B, Comprising: It corresponds to a part of FIG. On the other hand, (b) of each figure is a figure which shows the contact timing of 11 A of 1st function terminals, the 1st function terminal 21A, and the 2nd function terminal 11B, and the 2nd function terminal 21B in the state shown to (a). It corresponds to a part of the horizontal cross section of the header 10 and the receptacle 20. Therefore, (a) and (b) in each figure show the contact between the first function terminal 11A and the first function terminal 21A, the second function terminal 11B and the second function terminal 21B at a certain contact timing as a set. It can also be said that the relationship between the contact between the signal terminal 31A and the signal terminal 41A and the contact between the signal terminal 31B and the signal terminal 41B is shown. However, in order to simplify the description, it is assumed here that the degree of protrusion on the fitting side (receptacle 20 side) of the signal terminal 31A and the signal terminal 31B is set to be equal to each other. It is set so that it can contact at the same timing as the signal terminal 41B.

  When the header 10 and the receptacle 20 are fitted, first, the first functional terminal 11A and the first functional terminal 21A come into contact as shown in FIG. 9, and then, as shown in FIG. 10, the signal terminal 31A and the signal terminal 41A Alternatively, the signal terminal 31B and the signal terminal 41B come into contact with each other, and finally, as shown in FIG. 11, the second function terminal 11B and the second function terminal 21B can come into contact with each other. In such contact timing, for example, when the first function terminal 11A and the first function terminal 21A are used as ground terminals, and the second function terminal 11B and the second function terminal 21B are used as power terminals, respectively, Through the contact between the first functional terminal 11A as the ground terminal and the first functional terminal 21A, the potential of the header 10 and the receptacle 20 can be made common, and then the signal terminal 31A and the signal terminal 41A as the signal terminals, or The generation of noise is suppressed through the contact between the signal terminal 31B and the signal terminal 41B, and finally, the connection between the boards is ensured through the contact between the second function terminal 11B and the second function terminal 21B which are power supply terminals (detection terminals). Can be confirmed. In addition, in the structure where the fitting lock is made, it can be confirmed that the signal terminals are in contact with each other when the lock is made, whereas the inter-board connection has no fitting lock. Since the structure is not used, it is not possible to confirm that the contact is made when the lock is made. On the other hand, in the design example of the present application, although the fitting lock is not made, it can be confirmed that the signal terminals are in contact with each other when electricity flows between the power supply terminals and between the functional terminals.

  12 to 14 show another design example of the contact timing. In this design example, as shown in FIG. 12, first, the first function terminal 11A and the first function terminal 21A contact each other, and then, as shown in FIG. 13, the second function terminal 11B and the second function terminal 21B Finally, as shown in FIG. 14, the signal terminal 31A and the signal terminal 41A, or the signal terminal 31B and the signal terminal 41B can come into contact with each other. In such contact timing, for example, as in the above example, when the first function terminal 11A and the first function terminal 21A are used as ground terminals, and the second function terminal 11B and the second function terminal 21B are used as power terminals. First, the first function terminal 11A as the ground terminal and the first function terminal 21A are brought into contact, and then the second function terminal 11B as the power supply terminal (detection terminal) and the second function terminal 21B are brought into contact with each other. In addition, the signal terminal 31A and the signal terminal 41A, which are signal terminals, or the signal terminal 31B and the signal terminal 41B can be brought into contact with each other. Thus, by adjusting the degree of protrusion of the terminals of the header 10 and the receptacle 20, and further setting the function of each terminal appropriately, the contact method can be easily designed freely. Furthermore, when the ground is to be strengthened, both the first function terminal 11A and the second function terminal 11B can be ground terminals. When the power is to be strengthened, both are the power terminals. You can also.
