を有する必要がある。BACKGROUND OF THE INVENTION In many connector assemblies, a male connector housing mates with a female connector housing to obtain the required electrical connection. When the male connector housing and the female connector housing are assembled, the male terminals are electrically connected to the corresponding female terminals. In these typical connectors, each male and female terminal is configured as a single post member, i.e., the contact portion and the mounting portion are provided on the same shaft. Generally, female terminals are elastically deformable, and male terminals are relatively inelastic. These connector assemblies require relatively large forces to engage or mate the male and female contacts. In addition, the shape of these terminals requires that the connector housing has a relatively large height because the mounting portion and the contact portion are provided coaxially.

い。[0003] US Patent No. 4,734,060 discloses a connector assembly using terminals having rod-like contacts. In this type of connector assembly, since the male and female terminals are both elastically deformable, the fitting force between the two housings can be made smaller than that described above. Due to the relatively simple shape of the contact portions of the terminals, the terminals can be closely contacted, so that the width and length of the connector housing can be minimized. However, the height of the connector housing cannot be significantly reduced because the mounting portion and the contact portion are along the same axis. This is not preferable for a high-speed connector having a problem of signal propagation delay time.

作用する。When the first connector housing 16 is correctly placed in the jig, the first connector housing 16 is moved to the first
It moves to engage with the circuit board 12. In particular, the first connector housing 16 is moved to engage the end face 220 of the circuit board 12. When the first connector housing 16 and the first circuit board 12 are moved into engagement, the circuit board fitting legs 58 engage the end surface 220 of the first circuit board 12. Note that the spacing between the free ends of the opposed mating legs 58 is less than the width of the first circuit board 12. As a result, the circuit board mating legs 58 first engage the circuit board 12 and the legs 58
Contact with 0. When the first connector housing 16 is further inserted into the first circuit board 12, the legs 58 are spread apart and slide on the surfaces of both side surfaces 212 of the circuit board 12. This movement continues until the first connector housing 16 is fully inserted on the circuit board 12, thereby placing the legs 58 in electrical contact with the conductive signal paths 210 on the circuit board 12. Legs 58
Electrical contact between the leg 58 and the signal path 210 is ensured by placing the leg 58 in a stressed position, so that a large normal force (normal pressing force) acts between the leg 58 and the signal path.

When mating occurs, the circuit board mating pins 74 also cooperate with the first circuit board 12. The pins 74 engage the end face 220 of the board as the board mating legs 58 begin to slide on the sides 212. At the time of fitting, as shown in FIG.
It must be aligned with the second opening 218. In order for pin 74 to be inserted through end face 220, the pin must apply a force to the sides to allow the pin to penetrate the material of the circuit board. This force is generated by the jig in which the first connector housing 16 is arranged. Insertion of the pins into the sides of the circuit board does not damage busbar 70 or housing 16 when the jig maintains busbar 70 and pins 74 in place with respect to the housing.

By forming the notch in advance, the insertion force required to dispose the pin 74 on the end face 220 of the circuit board 12 is reduced. As the insertion of the pin into the end face 220 continues, the pin 74 moves through the side wall 216 to the opening 218.

The tearing of the eighteen plated layers is as described above. However, in this embodiment, the groove forms a channel between the end of the plating layer and the mating leg. As shown, the groove may extend to the end of the mating leg or may be shortened. As a result, when the mating pin is soldered into the opening, the solder flows into the groove and exceeds the free end of the plating layer as shown in FIG. 18, thereby providing a mechanical connection between the first circuit board and the first connector housing. Increase the reliability of the connection. The dimensions of the groove vary depending on the thickness and malleability of the plating layer used in the opening. This groove must be dimensioned to tear rather than fit the opening.

ができる。The advantages of using a connector mounted on the side of the circuit board are various. First, as devices become more sophisticated, it is necessary to arrange more connectors on the circuit board. Due to the limited space available, a solution is needed to increase the number of connectors mated to the circuit board. According to the present invention, the end face and the side face of the circuit board are used for fitting the connector. Also, by locating the connector on the side of the circuit board, the signal transmission path is shortened, thereby minimizing the propagation delay associated with the connector. Further, by inserting the first connector housing 16 into the first circuit board 12, the jig can be removed from the housing.

When the connector housings 16 and 18 are moved to the assembly position, the first connector terminal 50 engages with the second connector terminal 150 to make the required electrical contact. When fitted, the enormous contact portion 62 of the first leg 54 of the first connector terminal 50 engages with the introduction surface 168 of the second leg 156 of the second connector terminal 150.

2 on the side of the second leg 156,56. The introduction surfaces 168, 68 serve several functions. First, a slight misalignment (positional deviation) of the terminal at the time of fitting is compensated. The introduction surface also moves the first leg 54, 154 to a stressed position so that the enormous contact portions 62, 162 create a large normal force on the second leg 156, 56 as the contact portion slides on the second leg. To As the fitting operation of the two connectors continues, the enormous contact portions 62 and 162 slide on the side surfaces of the second legs 156 and 56 and move to the complete assembly position shown in FIG. Since this sliding engagement of the enormous contact portions performs a wiping operation under a large normal force, a reliable electrical connection is made between the contact portions 62, 162 and the second legs 156, 56. Contact portions 62, 16 of first legs 54, 154
As 2 slides on the second legs 156,56, the walls of the housing prevent the first legs 54,154 from permanently deforming. In other words, the walls of the housing are located very close to the first legs 54, 154, preventing the first legs from deforming beyond their elastic limits.

に好適である。With this terminal structure, the height of the connector can be reduced. Since the entire length of the first legs 54 and 154 is used for the elastic beam, the height of the connector can be minimized. In other words, the stationary part of the terminal is provided on the second leg of the terminal, which is physically completely separate from the first leg. As a result, the first leg does not require any stationary part, so that the overall height of the first leg is minimized. Also, the second leg 56, 1
Note that 56 is used entirely as a stationary member, i.e., no elastic properties are required. Thereby, the second leg is fixed in the housing and can be used to stabilize the terminal in the housing. In addition, this terminal shape enables highly reliable electrical connection. Each terminal has two parallel parallel paths through which signals flow. This provides a redundant electrical connection and reduces the inductance by about half compared to a single signal path. This is particularly suitable for high-frequency high-speed signals.

As a result, the position of the bus bar 70 of the bus bar mating terminal 170 pulls the contact protrusion apart, so that the contact protrusion 176 adds the required normal force to the bus bar 70.

Since the first connector housing is fitted on the end face or side face of the first circuit board, the connection is made in a minimum space. This is particularly effective when the space on the circuit board is limited.

The structure of the shroud 190 prevents the first leg 154 from deforming prior to mating with the second leg 56 of the first connector housing 16. Shroud 190 also provides alignment of the connector housings when the two housings mate. Shroud 190 keeps the terminals in the correct position before the terminals are mated and prevents them from being damaged during mating.
