Description

  The present invention relates to a connector, and to a connector of pseudo coaxial structure.

  Heretofore, a connector having a so-called pseudo-coaxial structure, which has a flat plate shape and improves transmission characteristics, has been used for signal transmission of high frequency signals and the like where good signal transmission characteristics are required.

  This type of connector includes a plurality of connection terminals (a ground terminal and a signal terminal) mounted in parallel in male and female connector housings respectively, and the center ground terminal of the plurality is connected to the ground potential to be engaged. There is known a coplanar structure in which signal terminals on both sides of a plurality of states are surrounded by the ground potential ground (see, for example, Patent Document 1).

  However, in the conventional connector as described above, the plurality of signal terminals and the ground terminals are all configured by the same shape parts in which the plate material of the conductor is bent, and they are arranged in parallel. The design freedom of the connector which expands the width of the terminal (wiring pattern on the mounting substrate side) and the arrangement pitch has been limited. Therefore, in addition to the difficulty in controlling the impedance of the signal terminal, there is a problem that the product size becomes large.

  Also, in the conventional connector, a plurality of signal terminals and ground terminals of the same shape are inserted in parallel to the insulating resin portion of the connector housing, so all the stresses involved in the insertion of all the terminals in the insulating resin portion are all It is feared that the resin acts in the same direction, causing breakage or the like in the insulating resin portion.

  Furthermore, in the conventional connector, although shell-like fixed terminals are provided on the outer peripheral side of the male and female connector housings, neither of the two fixed terminals has a surrounding shape extending over the entire circumference of the connector housing. There is also a problem that the damage such as cracking of the insulating resin portion can not be effectively prevented.

  Therefore, the present invention aims to provide a connector capable of facilitating control of impedance without increasing the product size, and also provides a connector capable of effectively suppressing the destruction of the housing. The purpose is

The connector can be made as wide as possible and has excellent transmission characteristics.

  In the connector according to the present invention, the plurality of signal terminals have a bent shape corresponding to the uneven fitting surface shape with the plurality of other terminals, and the ground terminal is unevenly fitted with the plurality of other terminals It can be set as the composition which has a board surface which spans the whole area of combined depth.

  With this configuration, even if the contact surface between a plurality of adjacent signal terminals is bent corresponding to the concavo-convex fitting shape with a plurality of mating terminals, the plate surface of the ground terminal covers the entire area of the concavo-convex depth We can secure the shielding function.

  In the connector according to the present invention, the ground terminal may have a plate surface orthogonal to the contact surface of the plurality of signal terminals. In this case, adjacent signal terminals are arranged symmetrically with respect to the plate surface of the ground terminal.

  In the connector according to the present invention, the connector housing includes an insulating member for integrally holding the plurality of terminals, and a shell-shaped conductor extending in the separation direction of the plurality of terminals on the outer peripheral side of the insulating member. . In this case, the transmission characteristics can be expected to be improved by the pseudo coaxial structure, and cracking and the like of the insulating member can be effectively suppressed.

  FIG. 12 (a) shows an arrangement pattern of a plurality of lands 61a, 61b, 61c on the side of the first substrate 61 on which the plug 50 is mounted in the male and female connector sets including the receptacle 10 of this embodiment. FIG. 12B shows an arrangement pattern of a plurality of sets of lands 62a, 62b, 62c on the second substrate 62 side on which the receptacle 10 of the present embodiment is mounted.

  Although not shown in detail in FIG. 12, corresponding strip-shaped signal lines are connected to the plurality of sets of lands 61a of the first substrate 61 (three lands 61a in FIG. 12A), Corresponding strip-shaped signal wirings are connected to the plurality of sets of lands 62 a (three lands 62 a in FIG. 12B) of the second substrate 62.

  The plurality of signal terminals 12 to 14 of the receptacle 10 are connected to the plurality of lands 61 a of the first substrate 61, and the plurality of signals of the plug 50 are connected to the plurality of lands 62 a of the second substrate 62. The terminals 52 to 54 are connected.

  Next, the operation will be described.

  In the male and female connector set of the present embodiment configured as described above, the plurality of terminals 12 to 16 of the receptacle 10 include the plurality of signal terminals 12 to 14 and the ground terminals 15 and 16, and the ground terminals 15 and 16 However, it is comprised by the conductor board which has the plate surface 15a, 16a orthogonal to the separation direction of several signal terminal 12-14 comrades.

  Therefore, the dimension in the separation direction (left and right direction in FIG. 1) occupied by the ground terminals 15 and 16 among the plurality of signal terminals 12 to 14 can be narrowed not to the width of the plate but to the plate thickness or similar dimensions. .

  Therefore, the width of the ground terminals 15 and 16 in the direction (separation direction) in which the plurality of signal terminals 12 to 14 adjoin is reduced to about the plate thickness, whereby the lands 61 a and the second pair of the first substrate 61 are formed. The signal wiring patterns connected to the plurality of sets of lands 62a of the substrate 62 can be made wide in signal line width and wide in distance.

  As a result, the plurality of terminals 12 to 16 and the mounting substrate side are compared with the case where all of the plurality of signal terminals 12 to 14 and the ground terminals 15 and 16 are formed of conductor parts of the same shape without increasing the product dimensions. The degree of freedom in the design of the connector can be increased to widen the width of the wiring pattern and the arrangement pitch thereof. Therefore, in addition to facilitating control of the impedance of the signal terminal, the problem of an increase in product size is eliminated.

  Further, in the present embodiment, the plurality of signal terminals 12 to 14 and 52 to 54 have a bending shape corresponding to the concave fitting portion 10r which is the concave and convex fitting surface shape of the male and female connector housings 11 and 51. Reference numerals 15 and 16 have plate surfaces 15a and 16a that cover the entire area of the concave and convex fitting depth of the concave fitting portion 10r.

  Therefore, the contact surfaces 12a, 12b, etc. between the plurality of adjacent signal terminals 12-14 and 52-54 and the contact surfaces 52a-54a are bent corresponding to the concavo-convex fitting shape of the male and female connector housings 11, 51. Even in this case, the shielding function by the plate surfaces 15a and 16a of the ground terminals 15 and 16 can be secured over the entire area of the uneven depth.

  Furthermore, in the present embodiment, adjacent pairs of the plurality of signal terminals 12 to 14 and 52 to 54 are arranged symmetrically with respect to the plate surfaces 15a and 16a of the ground terminal, respectively, so it is preferable for impedance control. Terminal arrangement.

  In addition, in the present embodiment, at least one of the male and female connector housings 11 and 51, for example, the receptacle 10 has an outer periphery of the connector housing 11 as an insulating member for integrally holding the plurality of terminals 12 to 16 in a fitted state. It has a shell-like conductor 17 extending in the direction in which the plurality of terminals 12 to 16 are separated on the side.

  Therefore, in the receptacle 10, while the improvement of the transmission characteristic by pseudo | simulation coaxial structure can be anticipated, the crack etc. of the connector housing 11 can be suppressed effectively.

  Further, in the present embodiment, since the shell-like conductor 17 has a continuous surrounding shape on the outer peripheral side of the connector housing 11 over the entire circumference, fitting of the plurality of signal terminals 12 to 14 in the separation direction with respect to the connector housing 11 is performed. The fitting width of the ground terminals 15 and 16 is smaller than the combined width and the separated distance, and the separated distance is increased. Moreover, since the direction of action of stress due to the insertion (for example, press-fit) of the plurality of signal terminals 12 and the action direction of stress due to the insertion (for example, press-fit) of the ground terminals 15 and 16 are orthogonal to each other The stress is relaxed between the terminals 12 and 13 and between 13 and 14 by the insertion portion of the ground terminals 15 and 16, and the breakage due to a crack or the like is effectively suppressed.

  Thus, in the present embodiment, in the male and female connector set including the receptacle 10 and the plug 50, impedance control can be facilitated without increasing the product size, and the connector housing 11, By effectively suppressing the breakage of the connector 51, in addition to the improvement of the transmission characteristics by the pseudo coaxial structure, the function of suppressing the breakage of the connector housing 11 or the like as the insulating member can be further enhanced.

  That is, in the first embodiment described above, the receptacle 10 has the shell-like conductor 17 extending at least in the terminal separation direction on the outer peripheral side of the connector housing 11, but work hardening etc. The notch 17i considered was formed.

  However, in the present embodiment, such a notch is eliminated by changing the material and processing method of the shell-like conductor 17.

  In this case, in addition to the same effect as that of the first embodiment described above can be obtained, the electrostatic shielding property and the like of the shell-like conductors 17 and 56 connected to ground can be further enhanced.

  In each of the above-described embodiments, the ground terminals 15 and 16 of the receptacle 10 extend over the entire engagement depth region of the plurality of signal terminals 12 to 14 and the plurality of signal terminals 52 to 54 of the plug 50, and Although it was set as the arrangement | positioning and shape orthogonal to those uneven | corrugated fitting surfaces, you may incline with respect to an uneven fitting surface.

  In addition, the resin material of the connector housing 11 and the insert molding resin portion 55 is not particularly limited, and the number and material of the ground terminals 15 and 16 and the plurality of signal terminals 12 to 14 and 52 to 54 are not particularly limited. Of course, the shapes and materials of the members 17 and 56 are not particularly limited.

Then, for example, in combination with a board with a shield plate on which the plug 50 is mounted, a connection part, etc., a shield of a required pseudo-coaxial structure can be configured. Therefore, the plug 50 may not have the socket shape having the outer peripheral portion 58 to the extent that the shield plate is attached to the connection terminal portion of the coaxial cable.
