Description

Connector {Connector}

The present invention relates to a connector, and more particularly to a connector for operating a lance supporting the terminal installed inside the housing outside the housing.

The connector is composed of a terminal made of a conductive metal in the housing of the insulating material, is coupled to the mating connector to make an electrical connection. In this process, the terminal installed inside the housing is pushed by the process of being coupled with the terminal of the mating connector.

When the terminal is pushed inside the housing, it is pushed to the rear of the housing, in order to prevent this, a lance is placed inside the housing. The lance can be elastically deformed to have a cantilever shape. The front end of the lance hangs on one side of the terminal so that the terminal is installed in the housing without being pushed.

1 is a partial cross-sectional view showing a state in which a terminal is engaged by a lance inside a housing in a connector in the prior art. According to this, the housing 12 forms the skeleton and the outer appearance of the connector 10. The housing 12 is made of an insulating material and penetrates through the interior thereof, and a plurality of through spaces 14 are formed. Each of the through spaces 14 is provided with a terminal 22 to be described below.

The housing lance 16 is formed in the through space 14. The housing lance 16 is formed on the inner surface of the through space 14 so as to extend obliquely from the rear end of the housing 12 toward the tip. The housing lance 16 has an elastically deformable structure. The housing lance 16 serves to support the rear end of the engaging portion 24 of the terminal 22 to be described below. At the front end of the housing lance 16, a hook end 16 'which is engaged with the coupling part 24 is formed, and an operation protrusion 17 is formed to extend further to the front end than the hook end 16'. The manipulation protrusion 17 is a portion which receives a force for causing the housing lance 16 to elastically deform by a tool for rework.

The terminal 22 is formed of a conductive material, and is generally made by pressing a metal. The terminal 22 is installed inside the through space 14 of the housing 12. An engaging portion 24 is formed at the tip of the terminal 22. The engaging portion 24 is a portion that engages with the terminal of the mating connector. The coupling portion 24 is generally formed so that the inside thereof penetrates in the longitudinal direction of the terminal 22 in a form in which the mating terminal is inserted.

The rear end of the terminal 22 is provided with a barrel 28, the barrel 28 serves to secure the wire 29 to the terminal 22 and to electrically connect the terminal 22 and the wire.

However, the above-described conventional techniques have the following problems.

The housing lance 16 is operated by a tool for rework to release the coupling with the terminal 22. In other words, in order to separate the terminal 22 from the housing 12, the operating lance 17 of the housing lance 16 is operated by using a tool so that the housing lance 16 is released from the terminal 22. The 22 is separated in the through space 14.

However, in this process, there is a problem that the operation protrusion 17 of the housing lance 16 is damaged by the tool. If the operation protrusion 17 is damaged, it becomes difficult to operate the tool, and in severe cases, the housing lance 16 may not perform its function.

In the related art, in order to separate one terminal 22 from the housing 12, the coupling state with the mating connector must be released first. This is because the tool for manipulating the operation protrusion 17 of the housing lance 16 should be inserted from the front end side of the housing 12 into which the terminal of the mating connector is inserted.

An object of the present invention is to solve the conventional problems as described above, to release the terminal from the lance to separate from the housing without a separate tool.

Another object of the present invention is to enable the terminal to be detached from the housing even when coupled with the mating connector.

According to a feature of the present invention for achieving the object as described above, the present invention is a housing having a through space is formed through the inside and the housing lance formed in the through space, and installed in the through space and the And a terminal mounted on the housing lance and mounted in the through space, and an operation lever integrally connected to the front end of the housing lance and having a free end extending toward the rear end of the housing.

At the front end of the housing lance a hanger jaw for the terminal is formed is formed, the rear end of the housing lance is formed with a guide inclined surface for guiding the insertion of the terminal.

The housing is provided with a lever channel in which the operating lever is positioned in parallel with the extending direction of the housing lance.

A protruding portion is formed at a free end of the operating lever, and the protruding portion is exposed to the outside of the housing.

The protrusion is exposed to the outside through a portion of the housing that is exposed to the outside of the mating connector when the mating connector and the housing are engaged.

In the connector according to the present invention, the following effects can be obtained.

In the connector of the present invention, an operating lever is formed to extend from the front end of the housing lance to the rear end of the housing lance so that the housing lance can be separated from the terminal by operating the operating lever. In particular, when the front end of the operating lever is exposed to the outside of the housing there is an effect that can be easily separated without a separate tool.

In the present invention, since the operation lever protrudes to the rear end of the housing, and the operation lever is exposed to the outside even when the operation lever is coupled with the mating connector, the terminal can be separated by operating the operation lever in a state where the operation lever is not separated from the mating connector. There is also an effect.

Figure 4 is a cross-sectional view showing the configuration and use of the embodiment of the present invention.

Hereinafter, preferred embodiments of the connector according to the present invention will be described in detail with reference to the accompanying drawings.

As shown in the figures, the housing 30 forms the skeleton and appearance of the connector of the present invention. The housing 30 is made of an insulating material, generally made of synthetic resin. A plurality of through spaces 32 are formed by penetrating in the front-rear direction of the housing 30. The through space 32 is provided with a terminal 45 (see FIG. 4).

The housing lance 34 is provided in the through space 32. The housing lance 34 has a tip extending toward the tip direction of the housing 30. At the tip of the housing lance 34, a hooking jaw 36 protrudes. The hanger 36 is to be hooked on one side of the terminal 45 to be described below.

Connection legs 38 are formed at both ends of the middle portion of the housing lance 34 so that the lance 34 is integrally connected to the housing 30. Guide inclined surface 40 is formed in a portion extending toward the rear of the housing 30 than the portion connected to the connecting leg 38. The guide inclined surface 40 is inclined at the rear end of the housing lance 34. The guide slope 40 serves to guide the insertion of the terminal 45 to be described below.

A leg channel 41 is formed in the housing 30 in the same direction in which the housing lance 34 extends. The leg channel 41 is formed from the front end to the rear end of the housing 30 in this embodiment, but it is not necessary to do so and may be formed over a predetermined section in the longitudinal direction of the housing 30.

An operation lever 42 is positioned in the leg channel 41. The operation lever 42 is connected to the front end of the housing lance 34, the operation lever 42 extends in the same direction as the extending direction of the housing lance 34. That is, the operation lever 42 extends in parallel with the housing lance 34, and extends in the rear end direction of the housing 30. In the present embodiment, the operation lever 42 is extended to the rear end of the housing 30, but need not necessarily be. For example, when coupled with the mating connector, the free end of the operating lever 42 only needs to extend to a position that can be exposed.

A protruding portion 44 is formed at the free end of the operating lever 42. The protrusion 44 protrudes out of the housing 30. This is to allow an operator to easily manipulate the protrusion 44. However, the protrusion 44 does not necessarily protrude to the outside of the housing 30. For example, the inside of the lever channel 41 may be pressed by the operator's finger.

Meanwhile, the terminal 45 installed inside the through space 32 is made of a conductive material. The terminal 45 is made of metal, for example. The terminal 45 has a male terminal as an example in this embodiment, but may also be applied to a female terminal. A wire 47 is connected to the terminal 45. The wire 47 extends out of the housing 30.

Hereinafter, the use of the connector according to the present invention having the above-described configuration will be described in detail.

The terminal 45 is inserted into and installed in the through space 32 inside the housing 30. The terminal 45 is inserted into the through space 32 at the rear end of the housing 30. When the terminal 45 is inserted, a guide inclined surface 40 formed at the rear end of the housing lance 34 guides the terminal 45.

The hooking jaw 36 formed at the tip of the housing lance 34 is pressed by the terminal 45 to cause the housing lance 34 to elastically deform. Such elastic deformation of the housing lance 34 is maintained until the hanger 36 is hooked to one side of the terminal 45.

The state in which the hooking jaw 36 is hooked to one side of the terminal 45 is shown in FIG. 4, in which the terminal 45 is rearward when the terminal of the mating connector and the terminal 45 are engaged. Will not be pushed.

In the connector of the present invention used in combination with the mating connector in the state shown in FIG. 4, the terminal 45 may be separated from the housing 30 in a state where the mating with the mating connector is not separated.

This can be done by manipulating the operating lever 42 which is connected to the housing lance 34. When the projection 44 of the operating lever 42 is pressed in the direction of arrow A as shown in FIG. 4, the portion of the operating lever 42 connected to the housing lance 34 is moved in the direction of arrow B. As shown in FIG.

In this way, when the operation lever 42 is connected to the housing lance 34 is moved in the direction of the arrow B, the hanger 36 at the tip of the housing lance 34 is also moved in the same direction. As such, when the hanger 36 is moved, the hanger 36 hanging on the terminal 45 is separated from the terminal 45.

Thus, the terminal 45 is in a state where it can be pulled out of the through space 32 of the housing 30. That is, even when the terminal of the mating connector and the terminal 45 are coupled, when the wire 47 is pulled out, the terminal 45 exits from the through space 32. Of course, the terminal 45 can be separated from the housing 30 even when the connector is separated from the mating connector.

In the present invention, using the lever lever principle of the operating lever 42, the pressing jaw 36 formed at the front end of the housing lance 34 by pressing the operating lever 42 without a separate tool terminal 45 You get out of the state. Therefore, the terminal 45 may be detached from the housing lance 34 without damaging the hooking jaw 36, so that the maintenance of the terminal 45 may be performed more quickly.

The scope of the present invention is not limited to the embodiments described above, but may be defined by the scope of the claims, and those skilled in the art may make various modifications and alterations within the scope of the claims It is self-evident.

For example, although the lever channel 41 in which the manipulation lever 42 is positioned is formed in the illustrated embodiment, the lever channel 41 is not necessarily formed. That is, the operating lever 42 is positioned in the through space 32 and the free end of the operating lever 42 may be exposed to the outside of the housing 30.
