Description

[0001]
The present invention relates to a female electrical contact member.
[0002]
In particular, the present invention comprises a main body having a means for fixing to an electric conductor at one end and a member for receiving a male electric contact member at the other end, and the male electric contact member is accommodated in the main body. A member having a bush opened at its free end, and a member for receiving the male electrical connector member for securing the male electrical contact member to the conductor by an elastic tongue. The present invention relates to a female electrical contact member provided with a ring extending toward the means, the ring being constituted by a floating ring that slides on the bush, and a means for limiting the sliding of the ring in the bush. .
[0003]
[Prior art]
A female electrical contact member of the type described above is described in French Patent Application No. 97-00109 filed Jan. 8, 1997.
[0004]
In the above-described type of female electrical contact member, the bushing has a cut-out retaining tongue for securing the female electrical contact member within the passage of the housing member of the electrical connector and preventing movement.
[0005]
[Means for Solving the Problems]
As a result, the bushing must have good mechanical properties in order for the retaining tongue to be effective, so that the bushing is made of stainless steel, but this material has insufficient conductive properties. However, this would take into account the electrical contact member in two parts, the first part consisting of a bush secured to a crimped ear piece for securing the electrical contact member to the conductor, and the second part It consists of a crimped ear piece made of a copper alloy that is connected to a flexible connector and is a good conductor like a ring. The female electrical contact member having the two parts has complete rigidity over its length, but has a cost disadvantage.
[0006]
It is an object of the present invention to provide a female electrical contact member of the type described above that has high mechanical strength, good electrical conductivity and a very low manufacturing cost.
[0007]
[Means for Solving the Problems]
The present invention provides a pair of first caulking ear pieces for fixing to an electric conductor having an insulating covering at one end and a pair of second caulking ear pieces for caulking at the end of the bare conductor of the electric conductor, A bush having a free end opened so as to accommodate the male electrical contact member at the end, and an elastic clamp housed in the bush and being a good electrical conductor and gripping the male electrical contact member A female electrical contact member comprising a body with a ring to be formed, wherein the ring is attached to one end of a flexible braid that is a good conductor, and the other end is a pair of second caulking ear pieces A tongue piece cut out from a nearby body is fixed to the body, the body is formed from a material such as steel having good mechanical properties, and the material comprising the tongue piece and the second caulking ear piece is a material of the body Different from It is characterized in that is internally coated with a layer of material having good conductive properties than the material of the body.
[0008]
Therefore, the main body can be formed from stainless steel, which can be easily processed and assembled, and a female electrical contact member can be manufactured at a very low cost.
[0009]
The material having better conductive properties than the conductivity of the body is preferably a copper alloy.
[0010]
【Example】
The present invention will be described in detail with reference to the embodiments shown in the accompanying drawings.
[0011]
The illustrated female electrical contact member has a pair of first caulking ear pieces 2 at one end for caulking to an electric conductor having an insulation coating, and a pair of second electric caulkings for caulking at the end of the bare conductor of the electric conductor. It consists of a stainless steel body 1 formed to have a crimped ear piece 3.
[0012]
A recess 6 is formed in the vicinity of the second crimping ear piece 3 to provide a support surface 6a. The two cutout tongues 4 collinear with the recess 6 are bent on the support surface 6a in contact with the support surface 6a so as to fix one end of the flexible braided conductor 7. Is a good conductor, and the other end is fixed to the ring 10 by an ear piece 11.
[0013]
The ring 10 is formed from a copper alloy which is a good electrical conductor and is provided with an elastic clamp having two tongues 16 and two strips 15 forming a neck portion 15a for gripping a male electrical contact member. It is formed to have an opening 12 for inserting a male electrical contact member.
[0014]
At the end opposite to the crimping ear pieces 2 and 3, the main body 1 is extended by a bush 20, and two holding strips 21 and two bent portions 22 are cut out from the bush 20. The strip 21 is adapted to fix the female electrical contact member in the passage of the connector housing member, and the bent portion 22 forms a shoulder portion for cooperating with the lock key.
[0015]
The free end of the bush 20 can be provided with a counter member 23.
[0016]
A passage 25 through which the male electrical contact member passes is provided at the free end of the bush 20.
[0017]
The two openings 26 of the bush 20 have an edge that forms an inner protrusion at the end towards the ear piece 3, which inner protrusions of the ring 10 to limit the sliding of the ring 10 in the bush 20. A cradle 17 for the bent portion 14 is formed.
[0018]
According to the present invention, the portion of the main body 1 composed of the strip 4 and the crimping ear piece 3 is covered with the copper alloy layer 30. A copper alloy layer 30 on which the body 1 is formed and having better conductive properties than the material is laminated to these parts of the body 1. This provides electrical continuity from the ring 10 to the ear piece 3 and all components between these two members are good electrical conductors.
[0019]
The present invention is not limited to the above-described embodiments, and various modifications and changes can be made to the embodiments of the present invention without departing from the scope of the present invention.
[0020]
【The invention's effect】
In the present invention, since the main body is made of steel, its mechanical characteristics are strong, and the caulking ear pieces are coated with a layer of copper alloy having better conductivity than the main body material. And has an effect that the manufacturing cost is low.
