In describing the terminal block B according to the present invention, the direction reference is specified with reference to FIG. 1.

The side in which the fitting portion 31 of the socket 30 coupled to the coupling hole 11 of the panel 10 with the insulating sleeve 20 interposed therebetween is opened as an upper side, and the opposite side is set as the lower side.

First, as shown in FIGS. 1 and 2, which are perspective and cross-sectional views of a terminal block according to the present invention, respectively, the terminal block B according to the present invention includes a panel 10, an insulating sleeve 20, and a socket 30. It is done by

The panel 10 may be provided in a device for reproducing or relaying various images, sounds, or various signals or training training equipment, and a circular coupling hole 11 having a predetermined diameter is formed.

The insulating sleeve 20 is formed of a synthetic resin, which is an electrical insulator, and also has a circular insertion hole 21 in the center thereof.

The socket 30 has a fitting portion 31 into which a plug (not shown) (particularly, a banana plug) is inserted and formed of a conductive material.

1 and 2, the insulating sleeve 20 is not essential,

Mainly, when viewed from the top of the insulation function and the panel, the locking projection 23 is exposed to the socket 30, the locking flange 33, so as to distinguish the function by the color of the unique red blue black and the like.

The insulating sleeve 20 has a locking ring projection 23 protruding outwardly at an upper end thereof to prevent the sleeve 20 fitted in the panel 10 coupling hole 11 from being separated downward. do.

In addition, the lower portion of the sleeve 20, in detail, the lower resistance projections directly below the round jaw 23,

More specifically, the plurality of resistance protrusions 25 forming a straight line from the top to the bottom are projected apart from each other.

Assuming a state cut in the transverse direction is repeated irregularities (요) is formed on the outer peripheral surface of the sleeve (20)

Idle rotation of the sleeve 20 inserted into the panel 10 coupling hole 11 is prevented through the locking projection 23.

Since the resistance protrusion 25 of the insulating sleeve 20 has a tapered thickness in the form of upper and lower heights, as can be seen in the lowermost cross-sectional views of FIGS. 1 and 2.

As the sleeve is inserted into the coupling hole 11 of the panel, the resistance protrusion 25 of the sleeve may be more tightly adhered to the inner wall of the coupling hole 11, thereby serving as a kind of wedge, Upward separation breakaway,

Eventually it may contribute to preventing the separation of the upward direction of the [sleeve 20 and the socket 30 combination].

On the other hand, the inner peripheral surface of the insulating sleeve 20 is formed with one upper thickness increasing portion 29 and two lower departure preventing portions 27a and 27b in the form of annular projections.

Next, the conductive socket 30 coupled to the insertion hole 21 of the insulating sleeve 20

The wire coupling portion 32 having a smaller diameter than the other portion is formed at the bottom, so that when connecting the socket 30 and the socket assembled to the panel 10 with the wire as necessary, the thin wire (W) (See Fig. 4) to facilitate soldering.

In addition, the upper end of the socket 30 is formed with a latching flange 32 protruding outwards so that the socket is coupled to the sleeve 20, the insertion hole 21 is seated in the peripheral receiving portion (23A),

In addition, it has a size that takes the circumference of the coupling hole 11 of the panel 10 so that it is no longer moved to the bottom, it corresponds to one of the core of the present invention.

The socket 30 has a non-slip part 35 knurling in the vertical direction on the outer circumferential surface thereof to increase frictional resistance with the inner circumferential surface of the insertion hole 21 of the insulating sleeve 20 to prevent idle rotation. Be sure to

On the other hand, in the insulating sleeve 20, the portion of the annular protrusion structure of the separation prevention portion, in particular the lower separation prevention portion (27b) and the portion coupled to the male and female

It is implemented by the corresponding ring groove 37 having a ring groove shape on the outer peripheral surface of the socket 30,

The corresponding annular groove 37 is formed by concave in the outer portion of the upper portion and the annular projection 39 of the lower portion smaller than the portion,

Annular projections (27a, 27b) of the sleeve 20 is made up of two upper and lower stages may be for coupling different types of sockets.

Alternatively, the release preventing portion of the sleeve may be in the form of a recessed groove, and the corresponding coupling portion of the socket may be deformed and introduced into the shape of the protrusion.

Subsequently, the thickness increase portion 29 of the inner circumferential surface of the insertion hole 21 of the sleeve 20 is

As can be seen in FIG. 4 in which the expanded portion 29A, the separation preventing portion 27a, 27b, and the thickness increasing portion 29 are slightly exaggerated,

Located in the assembled state directly under the panel 10, overlapping the portion directly under the non-slip portion 35 of the socket 30 is coupled

Since it is swollen outward by the characteristics of the synthetic resin material of the sleeve 20 that can be deformed by pressing to form the expansion portion 29A,

[Combination of sleeve 20 and socket 30] to some degree to prevent the separation of the upper part of the panel 10

More specifically, since the panel 10 is located between the Gurley annulus 23 of the sleeve 20 and the expansion portion 29A, the up and down breaks and swings of the [sleeve 20 and the socket 30 combination] are performed. To prevent.

The function of this inflation section 29A

The resistance protrusion 25 of the insulating sleeve 20 mainly contributes to preventing the idle of the sleeve and assists in preventing the [sleeve 20 and the socket 30 combination] from the panel 10 from being separated and separated. ,

The separation prevention function of [combination of sleeve 20 and socket 30] is completed to block the departure.

On the other hand, the separation preventing portion (27a) (27b) and the thickness increasing portion 29 of the sleeve 20 is formed of the same structure and size, but can be appropriately modified as necessary,

In the assembled state, the upper release preventing portion 27a of the sleeve having the same shape as the thickness increasing portion 29 is not coupled with the corresponding annular groove 37 of the socket 30, such as the expansion portion 29A. Because it serves to inflate the sleeve to the outside,

In some cases, the combination of the sleeve 20 and the socket 30 may be used to prevent separation and separation of the panel 10.

The heat-reducing sleeve 20, which is usually made of a general-purpose synthetic resin material and has a slight elasticity (to be deformable), has a locking ring 23 to repeatedly insert a plug, in particular a banana plug, into the socket 31 fitting portion 31. May not be able to provide sufficient support to prevent it from deviating from its fixed position.

In order to solve this problem, as mentioned above, the socket-insulating sleeve assembly, in particular, the socket 30 serves to prevent the socket 10 from falling into the lower portion of the panel 10 coupling hole 11.

The latching flange 32 of the socket 30 has a size that is caught around the coupling hole 11 of the panel 10 so that the locking flange 32 can no longer be moved downward, and corresponds to one of the cores of the present invention. do.

Along with this, another core of the present invention is a detachment preventing member 40 which can prevent the socket-insulating sleeve assembly, in particular, the socket 30 from escaping above the panel 10 coupling hole 11.

As shown in the coupling partial cross-sectional view at the bottom of FIG. 2, the release preventing member 40 has a corresponding fastening portion coupled to the fastening portion of the socket 30, and the coupling hole 11 of the panel 10. It is arranged in contact with the lower peripheral part and the upper end.

1 and 2, the fastening portion of the socket 30 corresponds to a spiral portion 34A, in particular a male screw portion,

The corresponding fastening portion of the release preventing member 40 is a female screw portion located in the spiral portion 43A, particularly the lower locking jaw 41.

Although not shown, alternatively, the latching flange of the socket may instead function as a locking threshold of an insulating sleeve (especially when using a synthetic resin or other insulating material having a certain strength),

In addition or separately, the fastening portion of the socket may be formed in the insulating sleeve to be deformed to be coupled to the corresponding fastening portion of the separation preventing member.

Next, as shown in Figure 3, the fastening portion made of the spiral portion (34A) 43A is made of a fastening portion that is coupled in a snap type (one-touch coupling) method can improve the assembly convenience.

More specifically, the panel 10 coupling hole 11 is a similar ellipse shape (circular shape cut out of two symmetrical arc portions), as shown in a plan view in a right bottom circle of FIG. 3.

Then as shown in plan view in a second circle, respectively, in the upper right of FIG. 3,

The outer shape of the insulating sleeve 20 is a similar elliptic shape that can be coupled to the coupling hole 11, the insertion hole 21 is also the same shape with different sizes,

The outer surface shape of the socket 30 also has a corresponding shape coupled to the insertion hole 21.

However, the locking flange 33 of the socket 30 and the locking ring 23 of the insulating sleeve 20 need only have a size that is caught around the coupling hole 11 of the panel 10 and is shown in a circular shape. have.

However, as shown in plan view in the right third circle of FIG.

The release preventing member 40 is a hollow 45 is similar to the oval shape formed on the locking jaw 41,

The locking groove portion 34B of the socket has a circular shape having an outer diameter corresponding to the length of the portion connecting the two circular arc removing portions of the hollow 45,

When the separation prevention member 40 is coupled to the socket 30 and rotated at the position where the upper end thereof is in contact with the lower part of the panel 10, the snapping jaw 41 is caught between the upper and lower flesh 34C portions of the locking groove 41B. (One-touch) type can be fixed more easily.

In the modification shown in FIG. 3, the key points are a similar elliptical hollow 45 of the separation preventing member, a circular locking groove 34B and a locking groove 34B of the socket 30, and a lower flesh 34C.

If desired, the elliptical member may be deformed into various non-circular shapes,

The catching groove part 34B should be a size that can be accommodated in the hollow 45 irrespective of its shape, and the flesh 34C may have a catching protrusion 43B surrounding the hollow 45 when the release preventing member 40 is rotated. It can be any shape and size that can be caught.

Next, between the outer circumferential surface of the insulating sleeve 20 and the separation preventing member 40 is preferably provided with an anti-loosening means (U) of the male and female coupling type,

3, the arm member U2 of the insulating sleeve 20 when the separation preventing member 40 is rotated 90 degrees (as can be seen in the lowermost drawing of FIG. 3), as shown in a plan sectional view in each circle. ) And the male member (U1) of the separation preventing member 40 is coupled to prevent the separation of each fastening portion,

The function of the anti-loosening means (U) can also be introduced to the fastening portion consisting of the spiral portion (34A) 43A.

Subsequently, as shown in FIG. 4, the coupling portion 32 and the wire W of the socket 30 are preferably connected by solderless fastening means.

First, in [A] of FIG. 4, the exposed wire W2 exposed when the end of the cover W1 of the wire W is removed is inserted into the hollow N1 of the nut N-type solderless fastening means, and then the end is bundled. The binding portion W3 (possible to form an extension portion similar to the binding portion in various ways) is formed so that any separation of the wire W is prevented.

When the nut N is fastened to the male screw portion 32A of the socket 30 coupling portion 32, the wire and the socket coupling portion can be contacted.

Meanwhile, FIG. 4B shows a snap (one-touch) type solderless fastening means 50.

An end portion of the coupling portion 32 of the socket 30 has a projection 32B having an upper and lower narrow shape.

The upper hollow 51a side of the case 51 is opened. The gradual spring is formed when the blowing spring 53 has a squeezing portion similar in shape to the protrusion 32B and pushes the coupling portion 32 into the hollow 51a. 53 is deformed and returned to its original position to bite the projection 32B.

The protrusion 32B at the end of the coupling portion 32 of the socket 30 is prevented from being separated from the blotting spring 53 even when a force acts in the direction in which the socket 30 is pulled upward.

In addition, the case 51 is provided with a squeezing spring 55 having a recess 55 and a tooth 55a at an end thereof. The exposed line W2 of the wire W from which the sheath W1 is removed is provided. I'm going to ask

In this case, if the exposed line is twisted, it will be possible to reliably press.

Since the blotting spring 55 has both ends of upper and lower beams and teeth 55a are formed at the ends thereof,

When a force is applied in the direction in which the wire W is pulled out, the two teeth 55a bite the exposed line W2 more firmly, thereby preventing any separation.

Both springs 53 and 55 are both conductive materials and should be in contact with each other for conductivity.

It may be produced in various ways as needed.

In addition, the case 51, which is a non-conductor for realistic productivity, is manufactured through a process of joining two powders that are male or female by screwing or interference fit, or

The case may be molded by using an insert injection method in which the springs 53 and 55 are arranged in a mold.
