BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high-voltage electric wire used for connecting a high-voltage electric wire to a socket fitting for mounting a high-voltage terminal such as a distributor (distributor) of an internal combustion engine such as an automobile or an ignition coil (ignition coil). Connection terminals.

2. Description of the Related Art FIG. 9 shows a conventional example of a high-voltage electric wire connecting terminal 3 for connecting a high-voltage electric wire 2 to a high-voltage tower 1 such as a distributor or an ignition coil. The high-voltage tower section 1 has a socket metal fitting 5 for mounting a high-voltage terminal, in which an annular locking groove 4 is provided around the inner peripheral surface thereof.
Has been inserted. The high-voltage electric wire connecting terminal 3 is crimp-connected to the tip of the high-voltage electric wire 2. The tip of the high-voltage electric wire 2 is exposed by stripping the insulating coating 7 before the high-voltage electric wire connecting terminal 3 is pressure-bonded. Insulate the end of the core wire 8
Is folded over.

The connection terminal 3 for a high-voltage electric wire is formed into a predetermined shape by, for example, punching a rolled stainless steel strip and then pressing it. The terminal 3 has a substantially cylindrical shape and is fitted into the socket fitting 5. It has a fitting portion 10 and an electric wire crimping portion 11 for crimping and fixing the high voltage electric wire 2. Further, the cylindrical wall of the terminal fitting portion 10 is formed with an engagement projection 12 which is projected outward by press working. When the terminal fitting portion 10 is inserted into the socket fitting 5, the engaging projection 12 engages with the locking groove 4 of the socket fitting 5, so that the terminal fitting portion 10 comes out of the socket fitting 5. It is to prevent coming off.

Further, as shown in FIG. 9, an insulating cap 14 for covering the vicinity of the outer peripheral portion of the electric wire crimping portion 11 and the outer periphery of the high voltage tower portion 1 is fitted and fixed to the connection terminal 3 for such a high voltage electric wire. ing. Then, when the terminal fitting portion 10 is fitted into the socket fitting 5, as shown in FIG. 10, a step formed on the inner peripheral surface of the outer covering portion 15 of the insulating cap 14 covering the high voltage tower portion 1. When the upper edge 18 of the high-pressure tower section 1 comes into contact with the section 16, the socket fitting 5
The insertion length of the terminal fitting portion 10 into the inside is limited to an appropriate amount.

Therefore, in order for the engaging projection 12 to effectively function as a stopper, as shown in FIG.
When the upper edge 18 of the high voltage tower portion 1 is in contact with the step portion 16 of the insulating cap 14, the engaging projection 12 of the terminal fitting portion 10 of the connection terminal 3 for the high voltage electric wire is engaged with the locking groove 4 of the socket fitting 5.
You have to reach deeper inside. And for that purpose, as shown in FIG.
8 and the engagement groove 4 of the socket fitting 5 is H ₁ , and the dimension between the step portion 16 of the insulating cap 14 and the engaging protrusion 12 of the terminal fitting portion 10 is H ₂ , It is necessary to design the connection terminal 3 for the high-voltage electric wire and the insulating cap 14 so that H ₂ ≧ H ₁ .

That is, when H ₂ <H ₁ ,
As shown in FIG. 1, even if the terminal fitting portion 10 of the high-voltage electric wire connecting terminal 3 is pushed into the socket fitting 5 until the step portion 16 of the insulating cap 14 comes into contact with the upper edge 18 of the high-voltage tower portion 1,
The engagement protrusion 12 of the terminal fitting portion 10 does not reach the locking groove 4 of the socket fitting 5, and therefore, the high-voltage electric wire connection terminal 3 may come off from the socket fitting 5 due to vibration or the like during traveling of the vehicle. It may occur.

However, there are various sizes H ₁ on the side of the high-voltage tower section 1 depending on the vehicle type and the like. Therefore conventionally, for each type of dimension H ₁ of the high voltage tower portion 1 side, have been the practice to design a high-voltage wire connection terminals 3 and the insulating cap 14, such a response, many kinds of high-voltage power lines The connection terminal 3 and the insulating cap 14 have to be produced and managed, which causes a problem of cost increase.

[0008] Therefore, for example, the actual development Sho 60-147082.
In the high tension cord connecting device disclosed in Japanese Patent Publication, as a solution to such a problem, a plurality of engaging recesses are formed on the outer peripheral surface of the terminal metal fitting connected to the end of the high tension cord, and A connecting device has been proposed which electrically connects a high tension cord and a socket fitting by engaging an engaging protrusion of a spring wire embedded in a groove with the engaging recess. According to such a connecting device, since the dimension between the engaging concave portion of the terminal fitting and the step portion of the insulating cap can be widened, even with one type of terminal fitting, the concave groove of the socket fitting and the high voltage tower can be used. It is possible to accommodate various types of high-pressure tower parts having different dimensions from the upper edge of the part.

[0009]

However, in the high tension cord connecting device disclosed in Japanese Utility Model Laid-Open No. 60-147082, the engaging concave portion of the terminal fitting engages with the engaging convex portion of the spring wire. Since there are multiple engaging positions, it is difficult for the operator to grasp the proper insertion amount when inserting the terminal fitting into the socket fitting, and before the step of the insulating cap comes into contact with the upper edge of the high-voltage tower. There is a possibility that an incomplete insertion state may occur in which the insertion operation is completed.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to solve the above problems, and it is possible to cope with various types of high-voltage towers in which the positions of the locking grooves of the socket fittings are different with one type of connection terminal for high-voltage electric wire, and incomplete. An object of the present invention is to provide a good connection terminal for a high-voltage electric wire that does not cause problems such as insertion.

Achieved by a connection terminal for high-voltage electric wires, characterized by having a hole It is.

Preferably, the locking means has an engaging projection capable of elastically engaging with the locking groove, and is fitted in the terminal fitting portion so as to be movable in the terminal fitting direction. The fitting projection and the engaging projection can be locked to hold the fitting fitting at a plurality of positions along the terminal fitting direction of the terminal fitting, and the engaging projection can be used. This is achieved by the connection terminal for a high-voltage electric wire, which comprises a locking hole opened so as to project outward. Further, more preferably, the engagement holes are a plurality of holes opened at a plurality of locations along the terminal fitting direction of the terminal fitting portion, or the engagement is provided at a plurality of locations along the terminal fitting direction of the terminal fitting portion.

It is composed of a substantially cylindrical elastic base member that is elastically and tightly fitted inside the terminal fitting portion, and an engaging projection that is provided on the outer peripheral surface of the elastic base member.

[0013]

According to the above construction of the present invention, the socket fitting is locked in the terminal fitting portion fitted into the socket fitting for mounting the high voltage terminal in order to prevent the terminal fitting portion from coming off from the socket fitting. Since the fitting portion mounting body having the engaging projections that engage with the groove is movably arranged in the terminal fitting direction, the terminal fitting portion can be moved by moving the mounting position of the fitting portion mounting body. The position of the upper engaging projection can be easily moved.

In addition, the engagement projections correspond to the change of the position of the engagement groove of the socket fitting by the movement operation of the fitting portion mounting body, and correspond to the increase in the number of the fitting parts provided in the engagement portion. Therefore, the engagement position where the engagement protrusion engages with the engagement groove of the socket fitting can be limited to only one place. Further, the engaging projections can be locked at a plurality of positions along the terminal fitting direction of the terminal fitting portion so as to position and hold the fitting portion mounting body, and the engaging projections can project to the outside of the terminal fitting portion. With the configuration in which the locking hole opened as described above is provided, the engagement projection can fix the fitting portion mounting body at the same time as positioning and fixing, and at the same time prevent the terminal fitting portion from coming off from the socket fitting. Since it is not necessary to separately provide means for fixing the fitting portion mounting body to the terminal fitting portion, the structure can be simplified.

Further, since the elasticity of the fitting portion mounting body elastically and tightly fitted in the terminal fitting portion reinforces the elastic strength of the terminal fitting portion, the socket fitting and the connection terminal for the high-voltage wire are connected. The connection strength will be strong due to the mating of
Since the terminal fitting part and the fitting part mounting body can be independently connected to the socket fitting, it is possible to improve the reliability of electrical connection and mechanical connection of the connection terminal for a high-voltage wire to the socket fitting. .

And the engaging projection 27 of FIG. These engaging protrusions 27 project from one of the two pairs of upper and lower circular holes 25 on the terminal fitting portion 22, and when the terminal fitting portion 22 is inserted into the socket fitting 5, the fitting fitting 27 of the socket fitting 5 is inserted. By engaging with the locking groove 4, the terminal fitting portion 22 is prevented from coming off from the socket fitting 5. The elastic base 26 is formed by bending a metal plate into a substantially cylindrical shape so as to obtain a predetermined spring characteristic that elastically and tightly fits inside the terminal fitting portion 22, and the engaging projection 27 is elastic. Base 2
It is formed into a hemispherical shape by press working into No. 6.

That is, as shown in FIG. 3, the terminal fitting portion 2

Further, in the construction in which the fitting portion mounting body 23 is tightly fitted inside the terminal fitting portion 22 and the engaging projection 27 is projected from the circular hole 25 formed in the terminal fitting portion 22, The engagement protrusion 27 prevents the terminal fitting portion 22 from coming off from the socket fitting 5, and at the same time functions as a means for locking the fitting portion mounting body 23 to the terminal fitting portion 22.
Since it is not necessary to provide a means for fixing 3 to the terminal fitting portion 22, the structure does not become complicated.

Further, since the elasticity of the fitting portion mounting body 23 elastically and tightly fitted inside the terminal fitting portion 22 reinforces the elastic strength of the terminal fitting portion 22, the socket fitting 5 and the high voltage wire Since the connection strength by fitting with the connection terminal 20 is solid and the terminal fitting portion 22 and the fitting portion mounting body 23 can be independently connected to the socket fitting 5, the high-voltage electric wire for the socket fitting 5 can be connected. The reliability of the electrical connection and mechanical connection of the connection terminal 20 can be improved. Further, if the diameter of the circular hole 25 formed in the terminal fitting portion 22 is set to be larger than the outer diameter of the engaging projection 27 fitted into the circular hole 25, the circular hole 25 and the engaging projection are formed. The gap generated between the holes 27 and 27 absorbs a dimensional error with respect to the position of the engaging projection and the position of the locking groove 4 of the socket fitting 5, so that the product yield and the productivity can be improved.

FIG. 7 shows a connection terminal for a high voltage electric wire according to another embodiment of the present invention. This high-voltage electric wire connection terminal 30 can lock the engagement protrusion 27 to positionally hold the fitting portion mounting body 23 at a plurality of positions along the terminal fitting direction of the terminal fitting portion 22, and the engagement protrusion 2
7 is the same as the connection terminal 20 for a high-voltage electric wire of the above-described embodiment, except for the elongated hole 32 which is a locking hole opened so that 7 can project to the outside of the terminal fitting portion 22.

That is, the connection terminal 30 for a high voltage electric wire of this embodiment

Therefore, the engagement protrusion 27 is guided by the elongated hole 32, and the fitting portion mounting body 23 is easily moved in the terminal fitting direction. Of course, even with such a high-voltage electric wire connecting terminal 30, the same operational effect as in the case of the high-voltage electric wire connecting terminal 20 of the above-described embodiment can be obtained. Further, by providing the circular hole portions in three stages, the protruding position of the engagement protrusion 27 on the terminal fitting portion 22 can be adjusted more finely.

In each of the above embodiments, the fitting portion mounting body is a metal plate molded into a predetermined shape, but the material used for the fitting portion mounting body is not limited to the metal plate.
Further, the number and shape of the engaging holes and the engaging projections for protruding the engaging projections of the fitting portion mounting body are not limited to those in the above-described embodiments. For example, it suffices that at least one engagement protrusion is formed on the fitting portion mounting body, and the shape of the engagement protrusion is not limited to a hemispherical shape, and various shapes such as a conical shape and a cylindrical shape are considered. To be In addition, it is preferable to form the engaging protrusions by press working in terms of reduction of the number of parts and workability.
It is also conceivable to join those formed by separate parts by welding or the like. Further, a hole formed in the terminal fitting portion is simply lengthened along the terminal fitting direction so that the engaging projection can be projected to the outside of the terminal fitting portion so as to be engaged with the locking groove of the socket fitting. Alternatively, a fixing means such as a lance or a shape fitting portion may be separately provided as a hole for fixing the fitting portion mounting body at a predetermined position of the terminal fitting portion.

[0030]

According to the connection terminal for a high voltage electric wire of the present invention,
Fitting that has an engagement protrusion that engages with the engagement groove of the socket fitting to prevent the terminal fitting portion from coming off the socket fitting, which is fitted into the socket fitting for mounting the high-voltage terminal Since the part mounting body is disposed so as to be movable along the terminal fitting direction, the position of the engagement protrusion on the terminal fitting part can be easily moved by moving the mounting position of the fitting part mounting body. Therefore, one type of high-voltage electric wire connection terminal can be used for various types of high-voltage tower parts in which the positions of the locking grooves of the socket fittings are different.

Moreover, the engaging projection corresponds to the change of the position of the locking groove of the socket fitting by the movement operation of the fitting portion mounting body, and does not correspond to the increase in the number of equipment parts of the engaging portion. The engaging position where the engaging protrusion engages with the locking groove of the socket fitting can be limited to only one position. Therefore, when inserting the terminal fitting part into the socket fitting, it is easy for the operator to grasp the proper insertion length, and before the step part of the insulating cap put on the connection terminal for the high voltage electric wire comes into contact with the upper end surface of the high voltage tower part. There is also no risk of causing an incomplete insertion state in which the insertion operation is finished.

Further, the engaging projections can be locked at a plurality of positions along the terminal fitting direction of the terminal fitting portion so as to position and hold the fitting portion mounting body, and the engaging projections are located outside the terminal fitting portion. In the structure in which the locking hole opened so that it can be projected to is provided, the engaging projection can fix the fitting portion mounting body, and at the same time, prevent the terminal fitting portion from coming off from the socket fitting. Therefore, it is not necessary to separately provide a means for fixing the fitting portion mounting body to the terminal fitting portion, so that the structure can be simplified.

Further, the elasticity of the fitting portion mounting body elastically and tightly fitted in the terminal fitting portion reinforces the elastic strength of the terminal fitting portion, so that the socket fitting and the connection terminal for the high-voltage wire are connected. Since the connection strength by the fitting is strong and the terminal fitting part and the fitting part mounting body can be independently connected to the socket fitting, the electrical connection of the connection terminal for the high voltage electric wire to the socket fitting and the machine Reliability of the dynamic connection can be improved.
