Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a power supply connector, and particularly to a connection structure between contacts and electric wires included in the connector.

[Conventional technology]

Power supply connectors that mainly allow large currents are often installed in a limited space within a device incorporating this connector.

Conventionally, this type of connector includes a housing 1 and contacts 2 held inside the housing 1, as shown in FIG. Inside the housing 1, a crimp portion 3 is formed at one end of the contact 2. The electric wire 4 is connected to the crimp portion 3 by crimping the crimp portion 3 from the outside toward the axial center of the contact 2 after insertion. The crimp-connected electric wire 4 is bent in a direction perpendicular to the axial center of the contact 2 and led out of the housing 1.

When the illustrated female contact 2 is used, the crimp portion 3 of the contact 2 is required to be subjected to a smoothing treatment so that it is easily plastically deformed. On the other hand, the contact portion 5 located on the side opposite to the crimp portion 3 of the contact is required to have high material hardness and spring properties.

In such a connector, a mating contact (not shown) is received in the contact portion 5 of the contact 2 to establish an electrical connection.

[Problem that the invention attempts to solve]

However, inside the housing 1, a relatively large space is required to bend the electric wire 4 connected in the same direction as the axial center of the contact 2. Therefore, there is a problem in that the external dimensions of the connector become large. Further, the crimp portion 3 of the contact 2 needs to be smoothed, so that the total length of the contact 2 becomes longer. Therefore, this also increases the external dimensions of the connector.

Therefore, an object of the present invention is to provide a compact power connector in which the total length of the contacts is shortened, and the connecting portion between the electric wire and the contacts is also shortened.

[Means and actions for solving problems]

According to the present invention, the present invention includes an insulating housing, a conductive contact built into the housing, a round crimp terminal and a screw part for connecting an electric wire to the contact, and the contact is arranged in the axial direction. The round crimp terminal has a contact part for making contact with a mating contact at one end, and a threaded part parallel to the shaft center at the other end, and the round crimp terminal has a contact part for making contact with a mating contact, and the other end has a threaded part parallel to the shaft center. There is obtained a power supply connector characterized in that one end is connected to the threaded part and extends perpendicularly to the axial center of the contact, and the other end has a round crimping part for crimping the electric wire.

〔Example〕

FIG. 1 shows an embodiment of the power connector of the present invention. The illustrated connector includes an insulative housing 11 and conductive contacts 12 built into the housing 11.
A threaded portion 13 is formed at one end of the contact 12 . A round crimp terminal 14 extending perpendicularly to the axial center of the contact 12 faces the axial end surface of the threaded portion 13 . The round crimp terminal 14 is
One end thereof is fixed to the threaded portion 13 of the contact 12 using a screw component such as a screw 15.
A round crimp portion 16 is formed at the other end of the round crimp terminal 14 . The crimp portion 16 has this crimp portion 16.
An electric wire 17 is inserted in the axial center direction. The electric wire 17 is crimped and connected to the round crimp terminal 14 by crushing the crimping portion 16 from the outside toward the axial center.

Note that such contacts 12 and connecting parts such as round crimp terminals 14 and screws 15 are included inside the housing 11. The illustrated female contact 12 has a connecting portion 18 at the end opposite to the crimp portion 13 for receiving a mating contact (not shown).

The connector manufactured in this manner uses the threaded portions 13 of the contacts 12 without being smoothed. Further, the electric wire 17 is connected to the round crimp terminal 14 inside the housing 11 without being bent. The connector is then provided at a required location within the power supply device.

[Effect of idea]

As explained above using the embodiments, according to the power supply connector of the present invention, there is no need for a portion to blunt the contacts. Therefore, the total length of the contact can be shortened. Further, since the electric wire does not require bending and the overall length of the housing is shortened, a compact power connector can be provided.
