<Operation of the first power contact>
Next, based on FIGS. 2A and 2B , the operation of the first power supply contact 4 having the above configuration when pressed by the pressing member 6 will be described. From the viewpoint of making the drawings easier to see, the illustration of the connection object F is omitted.

The connection object F can be inserted between the power connection leg 41 of the first power contact 4 and the locking leg 42 when the pressing member 6 is in the pressing release completion position OP. The power supply connection leg 41 can be electrically brought into contact with the land portion F2 of the connection object F at the contact portion 41a only by inserting the connection object F. In the state pressing member 6 is in the press releasing completion position OP, the contact portion 41a of the power supply connection legs 41, the connection object F Ru can make electrical contact with, but the contact in that case not stable ..

Therefore, the pressing member 6 is rotated ( moved ) to the pressing completion position CP shown in FIG. 2B to stabilize the electrical connection between the first power supply contact 6 and the connection object F, and to stabilize the electrical connection. Make sure that the connection object F is prevented from being removed. Specifically, when the pressing member 6 moves from the pressing release completion position OP to the pressing completion position CP , the pressing leg portion 43 of the first power supply contact 4 is pushed upward by the pressing portion 61 of the pressing member 6 and tilted. Displace. With the upward displacement of the push leg portion 43, the power supply connection leg portion 41 is tilted downward. With the downward displacement of the power connection leg 41, the connection object F is sandwiched between the contact 41a of the power connection leg 41 and the locking leg 42 of the first power contact 4 facing the contact 41a. As a result, the main fixing of the connection object F to the connector 100 is completed, and the contact portion 41a presses and contacts the land portion F2 on one surface of the connection object F , resulting in electrically stable contact. .. In FIG. 2B, the positions of the power connection leg 41 and the push leg 43 before the tilt displacement are shown by a two-dot chain line.

Along with downward displacement of the power connection legs 41, the contact portion 41a of the power supply connection leg 41, connecting object F and pressing contact. Since the connection object F is pressed downward by the pressing of the connection object F by the contact portion 41a of the power connection leg 41, the locking portion 42a of the locking leg 42 connects the connection object F to the connection object F. The locked portion F1 is also securely locked, and the removal of the connection target object F is surely prevented. As a result, more stable electrical contact between the contact portion 41a of the power supply connection leg portion 41 and the connection object F is achieved.

The resistance values ( Ω ) of the connector (Example 1) and other connectors (Comparative Example 1) having the configuration of the present invention based on the voltage drop when a power supply current is passed are compared below.

(Example 1)
The configuration of Example 1 is as follows.
A pair of first power supply contacts 4 of the present invention were arranged at both ends of the housing, and a pair of second power supply contacts 5 were arranged between the pair of first power supply contacts 4 and the signal contacts 2 and 3. The first power supply contact 4 and the second power supply contact 5 were connected in parallel.

-Thickness of the first power contact 4: 0.12 mm
-Route length of the power supply current of the first power supply contact 4: 2.10 mm
-Resistance value of the first power supply contact 4: 16.0 mΩ
-Thickness of the second power contact 5: 0.12 mm
-Route length of the power supply current of the second power supply contact 5: 2.10 mm
-Resistance value of the second power supply contact 5: 16.0 mΩ
-Resistance value of all 1st and 2nd power contacts connected in parallel: 8.0mΩ

(Comparative Example 1)
The configuration of Comparative Example 1 is as follows.
With arranging a pair of locking members only for locking the connection object to both ends of the housing, between a pair of locking members, first and second power contacts 4 and 5 of Example 1 of the present invention Instead of arranging, power contacts I and II using the same configurations as the first and second signal contacts 2 and 3, respectively, were arranged. That is, in Comparative Example 1, the signal contacts 2 and 3 were also used for the power supply contacts I and II for energization.

- power contact I thickness (using the same structure as the first signal contact): 0.08 mm
- power path of the power source current of the contact I Length: 2.60 mm
- Power supply contact resistance value of I: 24.0mΩ
- power contact II (second signal contact and use the same structure) thickness: 0.08 mm
- power path of the power source current of the contact II Length: 3.45 mm
- Power supply contact II of the resistance value: 30.0mΩ
· Connected in parallel with the power contacts I and II overall resistance value: 13.0Emuomega

Here, the "path length of the power supply current" is the length from the contact portion where the power supply contact contacts the object to be connected to the connection portion along the power supply contact.

In the first embodiment, the resistance value of the entire connector (more specifically, the entire first and second power supply contacts connected in parallel) was 8.0 mΩ. On the other hand, in Comparative Example 1, the resistance value of the entire connector (specifically, the entire power supply contacts I and II connected in parallel) was 13.0 mΩ. From this, it was found that in Example 1, the resistance value could be sufficiently suppressed (for example, 10 mΩ or less), and the performance as a connector was high.

Further, in the first embodiment, the pair of lock members (thickness: 0.08 mm) used in the first comparative example is not used, and the first power supply contact 4 also functions as a lock member, so that the lock member is locked. It is not necessary to provide the members independently. Therefore, in the first embodiment, the thickness of the first power supply contact 4 and the second power supply contact 5 can be increased by the plate thickness of the lock member, and the resistance value Ω can be sufficiently reduced.

Further, in the first embodiment , since the first power supply contact 4 having a fixing function that also serves as a lock member is used, even if the thickness of the first power supply contact 4 and the second power supply contact 5 becomes large, the core of the connector is increased. Since it is not necessary to increase the number and the pitch between the contacts in the housing 1 can be reduced by omitting the lock member, downsizing of the connector can be achieved.

According to the connector according to the present invention, a power supply connection function that allows a large current to flow while suppressing the resistance value of the entire connector, and a two-stage fixing function that enables temporary fixing of the object to be connected in the housing and subsequent main fixing by pinching.
