Description

[Detailed explanation of the idea] The present invention relates to a connector connection mechanism.

This type of connector connection mechanism can be used as a mechanism for connecting and separating connectors, and various types of connector connection mechanisms have been proposed in the past.

The present applicant is Utility Model Registration Application No. 110870 filed in 1978.
No. (see Japanese Utility Model Application Publication No. 54-36792) proposes a quick-connect/disconnect type connector equipped with this type of connector connection mechanism.

The structure of the connector is as shown in FIG. 1 of the accompanying drawings, but in order to make the present invention easier to understand, the mechanism and operation thereof will be summarized and explained here.

The connector Q in FIG. 1 consists of a plug 100 and a receptacle 200 that can be connected to each other.

In the plug 100, the male conductor 121 is connected to the insulator 111.
and is fixed inside the tubular body 118.

A thread is provided on the connection side end 118A of the tubular body 118, and the end tube 119 is screwed into the connection side end 118A.

The plug 100 is provided with an external body 115 as a connecting mechanism, and this external body 115 connects the coupling ring 1.
50 and a movable ring 160.

A spring 127 connects one end of the spring 127 to the end 11 of the end tube 119.
9AK is compressed and fixed with the other end facing the end 160A of the movable ring 160.

Coupling ring 150 is slidable over the front end portion of end tube 119 and is crimped at left end 150A to control sliding to the right in FIG.

The movable ring 160 connects the coupling ring 150 and the tubular body 11.
8, and is always biased by a spring 127 so that the tip 160B is pressed against a shoulder 150B provided at the tip of the coupling ring 150.

The movable ring 160 further has an internal medicine section 160C at its tip.
have.

On the other hand, receptacle 2001/I: female conductor 22
It is buried in the 0+'L insulator 213 and the tubular body 21
It is fixed inside the 7.

On the connection side of the tubular body 217, a small number of window portions 254 (in two locations in total) are provided around the connection side of the tubular body 217.

The connecting ring 258 consists of a head 253, legs 229 and fixing parts 230, and is made of a springy material.

When attaching the connecting ring 258 to the tubular body 217,
Insert the fixing part 230 first from the connection side (left side in the drawing).

At this time, the head 253 of the connecting ring 258 is connected to the tubular body 2
It is positioned within the window 254 of No. 17.

Cables are connected to the connection portion sides of the male conductor 121 and the female conductor 220, respectively.

When such a plug 100 and receptacle 200 are coupled, when the plug 100 is inserted into the receptacle 200, the inner flame part 253A of the head 253 of the connecting ring 258 and the oblique end 118B of the tubular body 118 come into contact. Due to the springiness of the leg portions 229, the inner flame portion 253
A is expanded in the radial direction.

From this state, connect the plug 100 to the receptacle 200.
When the head 253 is pushed in toward the outside, the outer protrusion 253B of the head 253 that protrudes outward from the window 254 hits the internal medicine part 160C of the movable ring 160, and the spring 127
is compressed, and the movable ring 160 is moved to the left in the drawing.

Further, when the plug 100 is pushed into the receptacle 200, the inner flame part 253A of the head 253 of the connecting ring 258 falls into the outer groove 118C provided in the peripheral part of the tubular body 118 by the force of the spring of the leg part 229. become.

Then, the outer protrusion 253B of the head 253 and the movable ring 16
A slight gap is created between the inner side 160D of
The outer protrusion 253 of the head 253 is returned to its original position as shown in FIG.
B is pressed by the inner side 160D of the movable ring 160.

This state is shown in FIG. In this state, male conductor 1
21 is inserted into the female conductor 220 and is brought into contact with the female conductor 220, thereby completing the connection between the plug 100 and the receptacle 200.

Even if the plug 100 is simply pulled back from the receptacle 200, the inner flame part 253A falls into the outer groove 118C and the inner side 160D presses the outer protrusion 253B from above, so the receptacle 200
The connection between the plug 100 and the plug 100 cannot be separated.

When it is desired to separate, move the coupling ring 150 to the left in FIG. 2 so that the spring 127 is compressed, and move the movable ring 160 to the left accordingly.
When the internal medicine section 160C of 60 reaches the position of the external protrusion 253B, if a force is applied to move the entire plug 100 backward to the left in FIG.
Since the inner flame part 253A is not limited by the inner side 160DK of the outer groove 118C, the inner flame part 253A is biased outwardly by the cam action of the right edge of the outer groove 118C and removed from the outer groove 118C, and the plug 100 is eventually removed from the receptacle 200. It will be separated from

The connection mechanism of such a connector has a structure that is easy to manufacture; only a pushing force is required to connect, and only a pulling force is required to separate, and the connection can be made no matter which part is gripped. Although it is excellent in that it can be attached and detached very quickly, it has the following problems.

That is, when the plug and receptacle are connected as shown in FIG.
The inner side 16 of the movable ring 160 fits snugly into the
If 0D is in close contact with the outer protrusion 253B,
Even if a load is applied that pulls the plug and receptacle apart from each other in the axial direction or pushes them against each other, the plug and receptacle will not move relative to each other in the axial direction if the force is less than the load that causes mechanical damage to each part and breaks it. There is no clutter that would otherwise occur.

However, in general, unless the machining accuracy of each part is made very strict, it is inevitable that the gap between the outer groove 118C and the inner flame part 253A fitted therein, and the inner part of the movable ring 160, as illustrated in FIG. Side 160D and outer protrusion 253B
Although the gaps are small, gaps C1 and C2 are created between the two.

Therefore, if a load is applied to the plug and receptacle that are connected to each other in the axial direction to pull them apart or push them against each other, the plug and receptacle will break even if the force is less than the load that will cause mechanical damage to each part. They will move relative to each other in the axial direction by the amount of the gap between them, that is, play will occur in the axial direction.

When the axial play becomes large in this way, it adversely affects the characteristics of the coupled device, and for example, noise is generated due to fluctuations in the contact resistance of the contacts, or in the case of coaxial cable connectors, noise is generated due to fluctuations in impedance. It is necessary to eliminate such axial play as much as possible, as it has negative effects such as deterioration of the voltage standing wave ratio.

An object of the present invention is to eliminate the drawbacks of the connector connection mechanism as described above, and to provide a connector connection mechanism with a structure that does not cause play in the axial direction during connection without significantly increasing processing accuracy.

Part 3 about the connector connection mechanism as an embodiment of the present invention.
The invention will be explained in detail below with particular reference to FIGS. 4 and 5. FIG.

FIG. 3 is a view similar to FIG. 1 showing a plug and receptacle of a connector according to an embodiment of the present invention, and this plug 100A has a movable ring 16σ
Other than the shape of the plug 118C and the dimensional relationship of the outer groove 118C, the plug 100 has the same structure as the plug 100 described above with reference to FIG. 1, and corresponding components are designated by the same reference numerals.

Further, the receptacle 200A is also similar to the receptacle 200A described above with respect to FIG.
0, and each corresponding component is designated by the same reference numeral.

The inner side of the movable ring 16σ of the plug 100A is similar to the inner side 160D of the movable ring 160 of the plug 100 in FIG.
It is not a horizontal surface, but an inner slope 160Yj.

In addition, the outer groove 118C of the tubular body 118 of the plug 100A
' is a hemispherical recess similar to the outer groove 118C of the plug 100 in FIG. It is made smaller and has an outer groove of 118C.
The inner flame part 253A fits snugly into the outer groove 118C', or rather, the inner flame part 253A does not completely fall into the outer groove 118C'.
The inner flame portion 253A' is designed to always be able to reliably engage the peripheral edge E of the outer groove 118C'.

The thickness of the tubular body 217' of the receptacle 200A is such that it can fit between the movable ring 16σ and the tubular body 118 when coupled to the plug 100A.

In addition, the radius of curvature of the hemispherical convex surface of the inner flame portion 253A' is set positively to the outer groove 118C' as explained with respect to the outer groove 118C'.
The radius of curvature is equal to or larger than the radius of curvature of the hemispherical concave surface of 18C'.

When connecting the plug 100A to which the present invention is applied and the receptacle 200A, the plug 100A
When inserted into the receptacle 200A, the inner flame part 253Al of the head 253 of the connecting ring 258 and the tubular body 11
The beveled end 1.18B of B comes into contact with the leg 229
The inner flame part 253A' is expanded in the radial direction due to the springiness of the inner flame part 253A'.

From this state, connect the plug 100A to the receptacle 200.
As the head 253 is pushed in toward A, the outer protrusion 253B of the head 253, which protrudes significantly outward, moves into the movable ring 16.
When the inner slope 16 of σ is reached, the spring 127 is compressed and the movable ring 160' is moved to the left in the drawing.

This state is shown in FIG.

Furthermore, when the plug 100A is pushed into the receptacle 200A, the inner flame part 253A of the head 253 of the connecting ring 258
' is an outer groove 118C provided on the periphery of the tubular body 118.
' by the spring force of the legs 229.

Then, the movable ring 160' is moved to the right in the drawing by the spring 127 by the amount that the outer protrusion 253B of the head 253 moves inward, and the inner flame part 253A' moves toward the right side in the drawing.
The outer protrusion 253B of the head 253 that has fallen into the outer groove 118C' of No. 18 is the inner slope 160D of the movable ring 160'.
' to hold it down.

This state is shown in FIG.

In this state, the male conductor 121 is inserted into the female conductor 220 and is in contact with the plug 100A and receptacle 200A.
The connection is completed.

Even if the plug 100A is simply pulled back from the receptacle 200A, the inner protrusion 253A' will not fit into the outer groove 11.
8C' and the inner slope 160D' presses down the outer protrusion 253B from above, so it is impossible to separate the connection between the receptacle 200A and the plug 100A.

When it is desired to separate, move the coupling ring 150 to the left in FIG. 5 so that the spring 127 is compressed, and move the movable ring 160' to the left accordingly. When a force is applied to move the entire plug 100A backward to the left so that the slope 160D' separates from the outer protrusion 253B, the outer protrusion 253B is no longer connected to the inner slope 160D of the movable ring 16σ.
', so the inner flame part 253A
' is biased outward by the cam action of the right edge E of the outer groove 118C' and removed from the outer groove 118C'6-, and eventually,
Plug 100A will be separated from receptacle 200A.

According to the structure of such a connector connection mechanism of the present invention,
Plug 100A and receptacle 2 as shown in Figure 5
00A, the radius of curvature of the inner flame part 253A' is designed to be equal to or even larger than the radius of curvature of the outer groove 118C', so that it always fits regardless of the processing accuracy of each part. In case of case, outer groove 118C'
A movable ring 160' in which the peripheral edge E and the inner flame part 253A' are securely engaged, and the movable ring 160' has an inner slope 160D'.
is always biased to the right by the spring 127, so the inner slope 160v is always biased towards the outer protrusion 2 regardless of machining accuracy.
53B and presses it.

Therefore, in the connected state shown in FIG. 5, the head 253 of the connecting ring 258 is
is tightly gripped between the peripheral edge E of the outer groove 118C' and the inner slope 160D' of the movable ring 160', and the plug 100A and the receptacle 200A are held tightly against each other in the axial direction. Even if the force is less than the load that would cause mechanical damage to each component and cause it to break, there will be no looseness that would cause the plug and receptacle to move relative to each other in the axial direction.

In the above embodiment, the outer groove 118C' was explained as a hemispherical recess provided in a part of the periphery of the tubular body 118, but this is a hemispherical recess provided along the entire periphery of the tubular body 1180. It may be a circular recess.

Further, in the above-mentioned embodiment, the inner flame part 253A' was described as a hemispherical convex surface, and the outer groove 118C' was described as a hemispherical concave part, but the present invention is not limited to such a shape, but can be formed into any shape, for example. It may have a polygonal cross section.

An example thereof is partially shown in FIG.

In the example of FIG. 6, the head 253' of the connecting ring 258' of the receptacle is formed with a hexagonal cross section, and the outer groove 118C'' of the tubular body 11B of the plug is also correspondingly formed into a recess with a polygonal cross section. has been done.

What is important here is that, as shown in FIG. 6, regardless of the machining accuracy of each part, the inner flame part 253A''
b The head 25 is designed so that it can always be reliably engaged with the peripheral edge E'.
The size of the hexagonal cross-section 3' is designed to be equal to or larger than the polygonal cross-section size of the outer groove 118.
