[0002]

2. Description of the Related Art In a conventional wireless device, an antenna 130 has an antenna element 131 as shown in FIG. 9, and the antenna element 131 has an internal steel wire shaft core (not shown). Is covered with a resin antenna tube. The antenna top sleeve 132 made of metal is attached to one end of the antenna element 131.
However, at the other end, the antenna top sleeve 13
Antenna bottom sleeves 133 made of the same material and having the same diameter as that of No. 2 are continuously provided.

A through hole 135 is formed in the metal 134 made of metal, a male screw portion is formed on the outer periphery of the metal 134, and a spring portion 136 is formed at the tip.
A slit 137 having an appropriate length in the axial direction from the end portion is formed in the spring portion 136, and the outer diameter of the tip is narrowed so as to be slightly smaller than the outer diameter of the antenna top sleeve 132. ing.

A female screw portion is formed on the nut 138, and a metal spring 139 is mounted on the nut 138, and an end portion of the spring 139 urges a printed circuit board 140 disposed above. It is like this. Case 14
3, an insertion hole 142 into which the metal 134 is inserted is formed, and a cover 141 is fitted in the case 143 to form a housing 150.

The antenna 130 is slidably inserted into the through hole 135 of the metal 134. At this time, when the antenna top sleeve 132 or the antenna bottom sleeve 133 passes through the spring portion 136, the tip end portion of the spring portion 136 is bent by the antenna top sleeve 132 or the antenna bottom sleeve 133 to exert an appropriate holding force.

The metal 134 having the antenna 130 inserted therethrough is inserted through the through hole 142 of the case 143, and the nut 138 is screwed into the male screw portion of the metal 134. By fastening the nut 138, Metal 134
Are held in the housing 150. The printed circuit board 140 arranged above the nut 138 has the spring 139 x.
Only the printed circuit board 142 and the antenna element 131 are simultaneously biased and urged, and the antenna top sleeve 1
32 or antenna bottom sleeve 133 and metal 1
34, a nut 138, and a spring 139.

[0007]

However, in the above-described structure, firstly, the male screw portion of the metal 134 and the female screw portion of the nut 138 are formed by cutting, so that both screw portions are formed. It takes a long time to perform the cutting process to do so, and since it is manufactured by machining, the pre-grinding and post-grinding parts of the raw material are not required, and the production time is prolonged and the cost is increased.

Further, since the fastening is performed by the screw portion, the worker has to turn the metal 134 several times to fasten it, which prolongs the assembly man-hour (tightening time), and
In order not to damage the threads of the male screw portion or the female screw portion, the work is performed while controlling the tightening torque of the male screw portion, which imposes a great burden on the operator.

Secondly, this type of wireless device is often used outdoors and is easily affected by the temperature. For example, when used in rainy weather, exposed to rain, exposed to the sunlight in midsummer, and sometimes left exposed to direct sunlight for a long time in an automobile, the surface temperature of the casing 150 is 80 ° C.
It is exposed to the extremely severe environment in which it goes over the temperature and returns to room temperature at night. Therefore, in the fastening by the screw portion, when the housing 150 and the metal parts are heated by the outside air, the parts made of different materials are expanded, and the parts are naturally cooled by the outside air and contracted. Since the difference is different, the expansion and contraction are repeated to cause loosening of the threaded portion, which causes the user who feels the looseness of the threaded portion to feel uncomfortable and uncomfortable, and sometimes makes the user think that it is broken.
Therefore, the adhesive is applied to the surfaces of the male screw portion and the female screw portion (fastening portion) or to the gap between the head portion of the male screw portion and the case 143, so that the cost is increased.

Thirdly, the high frequency signal radiated from the base station is received by the antenna and then transmitted to the printed circuit board 140 through the three parts of the metal 134, the nut 138 and the spring 139, or in this order. On the contrary, a signal is transmitted and a high-frequency signal is radiated from the antenna 130 toward the atmosphere. However, if the number of intervening parts is large, the contact resistance value of each part is the reception power or the transmission power. Lowers the antenna loss.
The effective gain as 30 was reduced.

Fourthly, the case 143 of the housing 150.
An insertion hole 142 into which the metal 134 is inserted is formed on the side surface of the mold. Since the insertion hole 142 is formed by a slide core movable in a direction orthogonal to the opening direction of the mold, The antenna 13 is complicated.
0 is assembled laterally with respect to the case 143, but the printed circuit board 140 is assembled from above, and the direction in which it is assembled is different from the parts arranged above the antenna 130. Therefore, after assembling the antenna 130 into the case 143, Since it is necessary to change the posture of the case 143, it is difficult to automate the assembly work.

Fifthly, in recent years, this type of wireless device has been made lighter or reduced in cost, and a housing 150 which is a resin molded product.
Since the wall thickness of the metal 134 and the nut 138 is also thinned due to the positive progress of the high cycle, the strength in the vicinity of the insertion hole 142 into which the metal 134 is inserted is reduced. Therefore, for example, the user accidentally drops the antenna 130 downward and hits the object or the like, and the vicinity of the insertion hole 142 is damaged.

Sixth, in the market, for example, when the antenna 130 breaks due to an unexpected situation, it becomes necessary to replace the antenna 130. However, since it has to be tightened with the above-mentioned tightening torque, it has to be returned to an assembly plant for replacement, and there are many problems that the time required for replacement is very long.

The present invention has been made in view of the above problems, and an object of the present invention is to hold an antenna in a housing without using a machined part and to reduce its assembly time. The cost is significantly reduced compared to the conventional one, and the cost is reduced. Further, the contact resistance value between the antenna and the printed circuit board is minimized to reduce the loss, and further, the strength of the holding portion is improved, and in the market,
An object of the present invention is to provide a wireless device with improved maintainability so that the antenna can be easily replaced.

A through hole 39 is provided in the center of the metal 3 so as to pass through the head 40 to the thin body 42.

As shown in FIG. 6, on the surface of the case 4, like the semi-cylindrical guides 9 and 10 described in the first embodiment of the present invention, the head 40 of the metal 3 is held while holding the metal 3.
Forming a first cylindrical guide 67 that surrounds the. In the second embodiment of the present invention, the case 4 and the antenna holder 2 are integrally formed, and the cover 5 and the case 4 are not divided at substantially the center of the metal 3 to be held. The shape guide 67 is formed in a cylindrical shape instead of a semi-cylindrical shape.

A second cylindrical guide 68 is provided inside the first cylindrical guide 67, and the first and second cylindrical guides 67 and 68 are connected by a plurality of connecting ribs 69 and 70. I am doing it. A cylindrical guide portion 49 and projection guide portions 50A and 50B, which will be described later, are formed inside the second cylindrical guide 68. Therefore, the inner diameter of the first cylindrical guide 67 is larger than the outer diameter of the head 40 of the metal 3, and the step difference between the first cylindrical guide 67 and the second cylindrical guide 68 is the head 40 of the metal 3. Is formed to a thickness greater than

Further, the case 4 has a cylindrical portion 4 of metal 3.

And the projection guide portions 50A, 50 for guiding the projections 43, 44.
B and the spring holding portion 52 are integrally formed. The spring holding portion 52 includes a metal urging spring 51 including a first urging spring portion 51A for urging the metal 3 in the guide direction and a second urging spring portion 51B for urging the printed circuit board 13. keeping. A convex portion 53 is provided in the middle of the first biasing spring portion 51A.

The metal biasing spring 51 is made by strengthening thin beryllium copper by subjecting it to age hardening treatment, and its positioning and mounting method are performed by shearing the end faces 51a, 51b.
The side guides 54, 55 forming the spring holding portion 52.
The lateral end surfaces 51c and 51d, which are also sheared, are brought into contact with the upper surfaces of the side guides 54 and 55 to regulate the height direction.
The first intermediate guides 56 and 57 that also contact the inner side of the spring to regulate the width direction and also form the spring holding portion 52, and are provided substantially in the middle of the first intermediate guides 56 and 57 and opposite to each other. The gap formed between the second intermediate guide 58 and the second intermediate guide 58 is equal to the plate thickness of the metal biasing spring 51, and the width of the gap regulates the depth direction.

The first projection guiding guide 59 is connected to the spring holding portion 52, and forms the projection guiding portion 50B together with the second projection guiding guide 61. And the second
The projection guide guide 61 of the first guide guide 59
The metal 3 is formed to be longer in the longitudinal direction and has a rotation preventing function of preventing the metal 3 from rotating in the direction opposite to the arrow D after the metal 3 is inserted into the cylindrical guide portion 49 and guided.

The rotation prevention guide 62 contacts the other projection 43 when the metal 3 is to be rotated by 90 ° or more, and prevents the rotation from continuing. Alternatively, it is formed integrally with the pull-out stopper 64 that prevents the metal 3 from moving in the direction opposite to the insertion of the metal 3 by providing a slight clearance.

The antenna 30 is the same as that of the first embodiment of the present invention. As shown in FIG. 7, the antenna 30 is slidably inserted and held in the through hole 39 of the metal 3. Inside the thin body portion 42 of the metal 3, a metal internal biasing spring 65 is housed at the lower end portion of the through hole 39. The metal internal biasing spring 65 has a cylindrical shape and is inserted into the metal 3. A notch 66 is provided on the front end side, and the outer diameter of the front end is slightly smaller than the diameter of the antenna top sleeve 33. Then, the thin body portion 42 is fixed to the metal 3 by applying a drawing deformation.

Then, the metal 3 constructed as described above
Are assembled in case 4 in the following operating sequence: That is, when the metal 3 is inserted into the case 4 from the direction of the arrow E, the curved surface portions 46A and 46B of the cylindrical portion 41 of the metal 3 are in the cylindrical guide portion 49, and the two protrusions 43 and 44 are in the protrusion guide portion 5.
0A and 50B are linearly guided in a non-rotatable state. Then, when the head portion 40 of the metal 3 is brought into contact with the end surface of the cylindrical guide portion 49, the protrusion 44 passes through the first protrusion guide guide 59 and becomes rotatable in the arrow D direction.

When this metal 3 is inserted and guided and rotated by 90 ° in the direction of arrow D, the first urging portion 51A of the metal urging spring 51 comes into contact with one of the projections 44 and bends, and the metal 3 Is inserted or biased in the guide direction. At this time the first
The convex portion 53 formed in the intermediate portion of the biasing portion 51A has the projection 44.
By engaging with the groove 47 formed in the front side, a click feeling can be felt before the end of the rotation, so that the worker can sense that the predetermined amount has been rotated and easily notify the work. .

In the assembled state after 90 ° rotation, for example, the user mistakenly pulls the antenna top 34 in the direction opposite to the insertion direction, and the metal biasing spring 51 is plastically deformed in the direction opposite to the biasing direction. There is a concern that the initial bias cannot be maintained. Therefore, the other protrusion 43 is
The protrusion 43 or the pull-out stopper 64 provided with a slight clearance is prevented from operating in the direction opposite to the insertion direction. Further, even if it is attempted to rotate by 90 ° or more, the projection 43 comes into contact with the rotation prevention guide 62 and the continuation of rotation is prevented.

Next, the operation will be described. In FIG. 7, when the metal 3 holding the antenna 30 is held by the case 4, the metal 3 is urged by the urging force of the metal urging spring 51.
Head 40 is brought into contact with the second cylindrical guide 68. At this time, if a force acts on the antenna 30 in the insertion direction of the antenna 30 (direction of arrow E), for example, if the user accidentally drops the antenna top 34 down during operation, the metal 3 is removed. Since the cylindrical guide portion 49, which is in contact with the second cylindrical guide 68 and into which the metal 3 is inserted, is connected to the first cylindrical guide 67, the stress acting on the base of the second cylindrical guide 68 is Because it is distributed around it,
Stress concentration can be avoided, and the strength in the vicinity of the cylindrical guide portion 49 can be increased.

Conventionally, as shown in FIG. 9, the seating surface of the head of the metal 134 is the upper surface of the housing 150 (or the cover 1).
No. 41 or one side surface of the case 143 is fixed, and since the case 143 is made of resin and has a small section modulus because it is thin, the strength of the head mounting portion of the metal 134 is extremely weak.

The cylindrical guide 4 into which the metal 3 is inserted
The enhancement method of 9 is not limited to the above-mentioned form,
A guide (not shown) serving as a reinforcing means is provided in the vicinity of the insertion hole 39 of the metal holder 2 for holding the metal 3 in a direction parallel to the axis of the antenna top sleeve 33.
It suffices to increase the section modulus in the insertion direction of the antenna 3, and specifically, it may be provided inside the outer diameter of the metal 3 and substantially parallel to the axis, for example, inside the case 4 and the antenna top. A protrusion (not shown) such as a rib arranged inside the outer shape of the antenna top 34 of the sleeve 33 and outside the insertion hole 39 of the metal 3 is erected integrally with the metal holder 2.

By dividing it, the assembly direction can be made the same as that of other contained items such as the printed circuit board 13, the receiver 5A, the liquid crystal display 5C and the like.

The advantage of integrating the case 4 and the metal holder 2 is that the number of parts can be reduced. Further, the mounting structure of the metal biasing spring 51 which is a thin leaf spring is, for example,
When the metal urging spring 51 has a plate thickness of 0.5 mm or less, it must be formed of a thin plate and a thin protrusion having the same thickness as that of the thin plate. Therefore, the protrusion is easily damaged and the die life is short. Therefore, as described above, the first intermediate guide 56,
57 and a second intermediate guide 58 so as to face substantially the middle of these first intermediate guides 56, 57 and be inserted into the gap formed by the first and second intermediate guides 56, 57, 58. If it is held, the thin portion of the mold is eliminated, the structure of the mold is simplified, and the life is extended.

The urging means for urging the metal 3 is not limited to those described in detail in the first and second embodiments of the present invention. For example, the head 40 of the metal 3 and the metal holder 2 can be used. A compression coil spring is provided by compressing between them, a spring washer is provided, a non-metallic elastic body such as urethane rubber, a rubber member such as silicone rubber, or urethane sponge,
A cushioning sponge member such as silicone sponge is interposed between the head 40 of the metal 3 and the metal holder 2 and is crushed to some extent from the initial thickness, and the restoring force is applied in the direction opposite to the insertion direction described above. The protrusions 43 and 44 of the metal 3 and the pull-out stopper 64 may be brought into contact with each other by obtaining a biasing force. That is, as long as the metal 3 is in the non-rotatable state, it may be either in the insertion direction or in the opposite direction.

Further, by providing a biasing means for biasing the projections 43 and 44 of the metal 3 to the rotation prevention guide 62 which is a rotation prevention member, the projections 43 and 44 of the metal 3 are always kept in the rotation prevention guide 62. Since it is abutted against, it can be prevented from easily returning to the rotatable state.

Next, a method of replacing the antenna will be described in detail with reference to FIG. As shown in FIG. 8, an antenna replacement jig 71 is used to replace the antenna 30. In this antenna replacement jig 71, a thin sheet metal is bent at a right angle, and a notch 72 having a width larger than the diameter of the antenna element 30A is formed at an end of the bent portion to form a pair of engagement piece portions 73. Is configured.

And, for example, in the market, the antenna 3
When 0 needs to be replaced because it is damaged or bent, it can be performed without separating (opening) the case 1 into the case 4 and the cover 5. That is, the antenna 30 is pulled out from the housing 1, and the pair of engagement pieces 7 of the antenna replacement jig 71 is
Groove 48 formed on the upper surface of the head 40 of metal 3
The antenna element 30 of the antenna 30 when engaged with
A is accommodated in the notch 72 in a non-contact state.

Next, the other end of the antenna exchanging jig 71 is grasped and rotated by a predetermined amount in the direction opposite to the metal 3 assembling direction, and then the antenna 30 is pulled out. It can be excluded from 1 and removed.

Further, when the metal 3 is assembled again, the antenna unit in which the metal 3 and the antenna 30 are integrally formed can be performed in the reverse order of this exclusion procedure.

Further, since the antenna exchanging jig 71 for removing these can be made of a very inexpensive material such as a cold rolled steel sheet, a simple and inexpensive repair is possible without returning it to the assembly factory for exchanging. The antenna can be easily replaced in a short time using the tool.

Also, in the case of the first embodiment of the present invention,
The antenna 30 is replaced by the same method of replacing the antenna 30 as described in the second embodiment.

The first semicircular guides 9 and 10 described in the first embodiment of the present invention and the first cylindrical guide 67 described in the second embodiment of the present invention are attached together. Antenna top 34 of antenna top sleeve 33
This is to prevent the antenna top sleeve 33 from being in contact with other electric products and containing noise during use, resulting in deterioration of antenna gain and sound quality. Further, for example, when the housing 1 is provided with a rod-shaped telescopic antenna and a protective cover for protecting the housing 1 from a liquid substance such as dust, water, or oil is to be attached, a hole is provided in the protective cover. By projecting the first semicircular guides 9 and 10 or the first cylindrical guide 67 through this hole, the housing 1 can be protected without hindering the sliding of the antenna 30.
