A cylindrical coupling member made of a spring material and having a plurality of bellows bent inwardly from the edge of the opening and having protrusions projecting inwardly in the middle thereof is formed in the opening, and the jack and The plug includes a shell provided with a protrusion corresponding to the protrusion at a position where the protrusion of the coupling member is pressed and displaced while the plug is fitted.

[Industrial application field]

The present invention relates to a connector having a cover, and more particularly to a connector coupling mechanism that reduces the cost, facilitates insertion/extraction work, and stabilizes characteristics by reducing the number of fitting and fixing members and mounting the connector externally.

[Conventional technology]

FIG. 2 is a diagram showing an example of a coupling mechanism of a conventional connector, in which (a) is an external perspective view, (b) is a plan sectional view of the main area indicated by the dashed line A in (a), and (C) 7) is a perspective view of the 7-pass.

In Figures (a), (b), and (c), I represents the completed jack on the cable side, and 6 represents the completed plug on the device side.

The completed jack 1 includes a jack 2 having a plurality of jack terminals 2a, a cover 3 made of zinc guid cast or the like on which the jack 2 is mounted, and two stoppers 4 disposed opposite to each other on both sides of the cover 3. It consists of Further, 5 is a cable consisting of a plurality of wiring members 5a.

The inner stopper 4 is made of a rectangular spring-like stainless steel plate with a thickness of about 0.5 m+++, for example, and has a collar 4a bent at approximately 90 degrees with a slight length left at one end. At the other end, a pressing part 4b is formed which is rounded and bent in the opposite direction to the flange 4a, and at the center of the shank, a rectangular bellows 40 along the elongated direction is formed with the pressing part 4b side facing toward the base. After the pressing part 4 is cut and raised as
The bellows 4 are formed so as to protrude toward the b-forming surface side, and the bellows 4
In the area near the base of the stopper 4, a substantially circular support shaft 4d is formed by the main body of the stopper 4 and the cut-up and separated bellows 40.

Further, inside the cover 3, there are provided at least a fixing mechanism section (not shown) that fixes the cable 5 near its introduction port and a mechanism section that can fix the jack 2, and at corresponding positions on both sides thereof. Above stopper 4
In particular, a circular bearing portion 3b is formed at a predetermined position within the groove 38, into which the support shaft 4d portion of the stopper 4 is fitted.

Therefore, the shower head 2 and the cable 5 with the wiring material 5a exposed are attached and fixed to a predetermined position inside the cover 3,
Each wiring member 5a of the cable 5 and each jack terminal 2a of the jack 2 are individually connected, and the stopper 4 is attached to the groove 3a formed on both sides of the cover 3 so that the support shaft 4d thereof is a bearing portion of the groove 3a. 3b, insert it so that it fits with
).

Note that this assembly work is performed with the cover disassembled.

In the completed jack l having this configuration, when the pressing part 4b of the stopper 4 is pressed from the outside as shown by the arrow B, the stopper 4 rotates on the support shaft 4d, and The collar 4a moves in the direction of the arrow B" shown in the figure, but since the bellows 40 in contact with the inner wall of the groove 3a of the cover 3 has the effect of rotating the stopper 4 in the opposite direction, when the pressure in the direction B by the pressing part 4b is removed. The stopper 4 is shown in the figure (
The state b) is reached.

This means that since the stoppers 4 are mounted on both sides, the gap between the two flanges 4a remains open only while the pressing portion 4b is being pressed in the B direction.

On the other hand, the complete plug body 6 includes a plug 7 having a plurality of plug terminals 7a, a housing 8 made of, for example, an insulator, and a zinc guide formed so that the plug 7 can be attached and fixed to the device side in that state. It is composed of a shell 9 made of cast material or the like.

In particular, the shell 9 has a predetermined area surrounding the area where the plug terminal 7a exists, which has a guide function to protect the plug terminal 7a and to ensure that the plug terminal 7a can be inserted and connected to the jack terminal 2a. height wall 9a
A protrusion 9b protruding outward from the wall 9a is formed at a position corresponding to the collar 4a of the stopper 4 inserted into the completed jack 1 on the end face of the wall 9a.

In this case, the ring body 8 of the protrusion 9b provided on the end face of the wall 9a
The height h of the side surface 9c from the surface 8a of the housing 8 is such that when the plug terminal 7a and the jack terminal 2a are connected at a predetermined position, the protrusion 9b and the collar 4a of the stopper 4 are on a broken line. They are set to mesh as shown by C.

Therefore, press the pressing portions 4b of the stoppers 4 at two locations on both sides of the completed jack 1 with your fingers to widen the gap between the collars 4a, and then move the completed jack 1 in the direction of the arrow.
When the connection between the two is completed, the finger is removed from the completed jack body 1 to completely connect the completed jack body 1 and the completed plug body 6.

In the connector coupling mechanism having such a configuration, the stopper 4
2 are required, and since the work of joining them is carried out while pressing the stopper 4 as described above, the force required for the joining work is divided into the pressing force of the stopper 4 and the fitting force between the plug terminal 7a and the jack terminal 2a. This has the disadvantage that it requires some skill in the joining work.

Another drawback is that, for example, when adding a new stopper or replacing an existing stopper, the cover must be disassembled.

[Problem to be solved by the invention]

Conventional connector coupling mechanisms have the problem that the coupling work requires skill because the two stoppers are coupled while being pressed at the same time, and since the stoppers are located inside the cover, it takes a lot of man-hours to attach and replace the stoppers. Additionally, since the wiring portion is exposed when the stopper is attached or replaced, there is a problem that there is a risk of secondary failures such as short circuits in the wiring portion.

[Means for Solving the Problems] The above problem lies in the coupling mechanism of the connector, which is composed of a jack housed in a cover and a plug provided with a shell that fits with the jack. a spring member which is fixed to the cover and has a plurality of bellows formed in the opening on the jack terminal side of the jack, the bellows being bent inward from the edge of the opening and having protrusions extending inward in the middle; a cylindrical coupling member, and a shell having a protrusion corresponding to the protrusion at a position where the protrusion of the coupling member is pressed and displaced and can be climbed over while the jack and plug are fitted together. The problem is solved by a connector coupling mechanism consisting of a plug and a plug.

(Function) If the connection between the plug terminal and jack terminal can be achieved by simply applying force in the mating direction, the connection work can be easily performed.

Furthermore, if the coupling mechanism for both is provided outside the cover, the coupling mechanism can be easily attached or replaced without disassembling a portion of the cover.

In the present invention, a coupling mechanism that can be coupled only by pressing force in the fitting direction of the plug terminal and the jack terminal is attached to the surface of the completed jack terminal to constitute the coupling mechanism section.

Therefore, it is possible to facilitate the connection work and also to allow the connection mechanism to be installed or replaced without exposing the wiring portion.

〔Example〕

FIG. 1 is a diagram showing an example of the coupling mechanism of the connector according to the present invention, and similarly to FIG. 2, (8) is an external perspective view.

(B) is a plan sectional view of the main region, and (C) is a perspective view of the coupling member.

In Figures (A), (B), and (C), 11 represents a completed jack on the cable side, and 16 represents a completed plug on the device side.

The completed jack 11 includes a jack 2 similar to that shown in FIG. 2, a cover 12 made of zinc cast or the like to which the jack 2 is attached, and a connecting member 1 attached to the outer periphery of the cover 12.
It is composed of 3. Note that 5 is a cable similar to that shown in FIG.

First, the cover 12 is provided with at least a fixing mechanism part for fixing the cable 5 and a mechanism part for fixing the jack 2, as explained in FIG.
A predetermined position on the outer surface has a width of, for example, 0.8 ms and a depth of 2 m all around the cover 12 so as to surround the cover 12.
A groove 12a of about m length is formed.

Further, the coupling member 13 is a rectangular cylindrical member formed by bending a rectangular springy stainless steel plate or the like with a thickness of about 0.5 mm to fit the outer periphery of the groove 12a forming area of the cover 12, for example. The opening on one side has a protrusion 13 that is bent inward from the end and protrudes inward midway.
A plurality of bellows 13b are formed, and a protrusion 13c with a height of about 1.5 m is formed in the opening on the other end side and is bent inward at approximately 90 degrees over the entire circumference. .

Note that cutouts 13d are provided along the ridgeline at the four corners of the opening on the side where the protrusion 13c is formed.

Therefore, the jack 2 and the cable 5 are attached and fixed at predetermined positions inside the cover 12 as explained in FIG. 2, and each wiring member 5a of the cable 5 and each jack terminal 2a of the jack 2 are individually connected. Once the cover is completed, the covered jack can now be constructed.

Next, the protrusion 13c side of the coupling member 13 is inserted into the notch 1.
When the protruding part 13c is inserted from the jack 2 side with the part 3d expanded outward, when the protruding part 13c reaches the groove 12a of the cover 12, the protruding part 13c fits into the groove 12a and the coupling member 13 will be fixed to the cover 12.

Figure (B) represents this state.

On the other hand, the plug complete body 16 includes the plug 7 described in FIG. 2, a casing 8 into which the plug 7 can be attached and fixed to the device side in that state, and a shell 17 made of zinc cast or the like.
It is made up of.

In particular, the shell 17 is provided with a wall 17a similar to that shown in FIG. 2, and a bank-like protrusion 17b protruding from the wall 17a at a predetermined height is formed around the outer periphery of the end surface of the wall 17a.

In this case, the distance h" from the center line C of the protrusion 17b provided on the end surface of the wall 17a from the surface 8a of the casing 8 is the distance h" when the plug terminal 7a and jack terminal 2a are fitted in a predetermined state. The projection 17b is set so as to just get over the projection 13a of the bellows 13 of the coupling member 13.

Then, when the completed jack body 11 is moved in the direction of the arrow, the protrusion 17b will climb over the protrusion part 13a of the bellows 13 when the fitting between the two is almost completed, and the completed jack body 11 and the completed plug body 16 will move over the protrusion 13a of the bellows 13. can be combined.

In this case, since only one connecting member 13 is required, the cost can be reduced, and the work of connecting the two can be done simply by moving the completed jack 11 in the direction of the arrow, so it is easy to do without special skill. It can be carried out.

Furthermore, for example, when adding a new coupling member 13 or replacing an existing coupling member 13, there is no need to disassemble the cover, and the wiring portion is not exposed, thereby suppressing the occurrence of secondary failures. can do.

〔Effect of the invention〕

As described above, according to the present invention, it is possible to provide a connector fitting mechanism in which the cost is reduced, the insertion/extraction work is facilitated, and the characteristics are stabilized by reducing the number of coupling and fixing members and mounting the connectors externally.

Although the present invention will be described with reference to the case where the coupling member is attached to the jack side, the same effect can be obtained even if the coupling member is attached to the plug side.
