Below, the resistance value ( Ω ) based on the voltage drop when the power supply current is passed is compared between the connector (Example 1) having the configuration of the present invention and the other connector (Comparative Example 1).

Example 1
The configuration of the first embodiment is as follows.
A pair of power contacts 4 having a first fixed function according to the present invention is disposed at both ends of the housing, and a pair of simple power contacts 5 are disposed between the pair of power contacts 4 having a fixed function and the signal contacts 2 and 3. did. The power contact 4 with a fixed function and the simple power contact 5 were connected in parallel.

-The thickness of the power contact 4 with the first fixing function: 0.12 mm
-Power supply current path length of the power supply contact 4 with the first fixing function: 2.10 mm
-Resistance value of the power contact 4 with the first fixed function: 16.0 mΩ
・ Thickness of simple power contact 5: 0.12 mm
-Power supply current path length of the simple power supply contact 5: 2.10 mm
・ Resistance value of simple power contact 5: 16.0mΩ
-Resistance value of the entire connector: 8.0mΩ

(Comparative Example 1)
The configuration of Comparative Example 1 is as follows.
A pair of locking members only for locking the connection object is disposed at both ends of the housing, and a first configuration having the same configuration as the signal contacts of the first and second embodiments of the present invention is provided between the pair of locking members. First and second power contacts were arranged. In Comparative Example 1, the signal contact was used for energization.

-The thickness of the first power contact: 0.08 mm
-Power supply current path length of the first power supply contact: 2.60 mm
-Resistance value of the first power contact: 24.0 mΩ
・ The thickness of the second power contact: 0.08 mm
-Power supply current path length of the second power supply contact: 3.45 mm
・ Resistance value of second power contact: 30.0mΩ
-Total resistance of first and second power contacts connected in parallel: 13.0 mΩ

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

  In Example 1, the resistance value of the entire connector was 8.0 mΩ. On the other hand, in Comparative Example 1, the resistance value of the connector was 13.0 mΩ. From this, it was found that the resistance value of Example 1 can be sufficiently suppressed (for example, 10 mΩ or less), and the performance as a connector is high.

  In Example 1, the pair of lock members (thickness: 0.08 mm) used in Comparative Example 1 are not used, and the power contact 4 with a fixed function also functions as a lock member. It is not necessary to provide the lock member alone. Therefore, in Example 1, the thickness of the outer side and the simple power source contact can be increased by the thickness of the lock member, and the resistance value Ω can be sufficiently reduced.

Furthermore, since the power contact 4 with a fixed function that also serves as a lock member is used in the first embodiment , the number of connector cores is increased even if the thickness of the power contact 4 with a fixed function and the simple power contact 5 are increased. The necessity of the lock member is eliminated, and the pitch between the contacts in the housing 1 can be reduced by the amount of omission of the lock member, so that downsizing of the connector can be achieved.

According to the connector according to the present invention, the power supply connection function that allows a large current to flow while suppressing the resistance value of the entire connector, as well as the two-stage fixing function that enables temporary fixing in the housing of the connection object and subsequent clamping and fixing. By providing the power contact, the connector downsizing was achieved.
