Description

Spring module for slide type terminal {Spring module for slide type terminal}

The spring module of the slide-type terminal, and more particularly, when the main body of the spring is rubbed when the slide body of the slide-type terminal withdrawal operation can prevent the occurrence of noise, the spring is It also solves the case where a lot of noise is generated by the scratching on the terminal, and prevents the breakage of the coil-type elastic part and the wire part of the wire part, which is the main part of the spring, by easily breaking the spring module of the new slide type terminal which improves the product reliability. It is about.

The slide type terminal is a terminal in which a slide body having a liquid crystal display is opened in a sliding manner by a predetermined length or is stored in a main body in a main body equipped with a dial keypad.

Such a slide type terminal has a structure having a slide unit so that the slide body can be pulled out or received in a slide manner in a main body provided with a dial keypad, and the slide unit is connected to the slide body and a fixed piece connected to the main body. At the same time, it consists of a slide piece that is slidably coupled relative to the stationary piece, and a spring for applying elastic force such that both ends of the slide piece and the stationary piece are connected to each other, and the slide body is drawn out from the main body or stored in the main body.

Various kinds of springs are adopted, and there are products employing the springs 5 shown in FIGS. 1 to 3. The spring 5 shown in Figs. 1 to 3 is integrally connected to the coiled elastic portion 7 and the coiled elastic portion 7 formed in the form of a snail, and hinge portions are respectively attached to the fixing piece and the slide piece. It is a structure which has a pair of wire part 9 connected by mediation. Reference numeral 9a denotes a ring portion for connecting to the fixed piece and the slide piece via the hinge portion.

When the slide body is fully closed with respect to the main body of the slide-type terminal (full close), the slide piece is pressed against the fixed piece by the elastic force of the spring (5), so that when the slide body of the terminal is completely closed It is possible to prevent the slide body from flowing with respect to the body.

On the other hand, when the slide piece is pushed upward in order to slide and slide the slide body and the slide piece from the lowest point position of the fixed piece to the highest point by the user in the closed state, the both ends of the coil-shaped elastic portion 7 As the pair of integrated wire rods 9 are bent in a direction facing each other, the elastic force acts, and at the same time, the coil-type elastic portion 7 is also pressed in the circumferential direction toward the center thereof, and the elastic force acts.

In this state, when the slide piece is continuously pressed by the user and pushed upward, the coil-shaped elastic part 7 of the spring 5 is unfolded by its own elastic force and the pair of wire parts 9 are also elastic. Since it is unfolded by the restoring force, even if the user no longer presses the slide piece, the slide body can be moved to the highest point with respect to the main body and can be completely opened.

As described above, if the slide body is pushed back into the main body to be in the closed state while the slide body of the slide type terminal is opened, the above-described process may be reversed.

On the other hand, the spring (5) when the slide body of the slide-type terminal is drawn out or received, the coil-shaped elastic portion 7 is also pressed in the circumferential direction to exert an elastic force, as well as a pair of left and right wire rods (9) ) Also bend each other to act as an elastic force, in the case of the conventional spring (5) shown in Figures 1 to 3 is composed of a substantially rectangular cross-section, when each part of the spring (5) Since each coil part 7a and 7b of the coil-shaped elastic part 7 is surface-contacted (refer FIG. 2) with a large area, there exists a problem that a lot of noise is produced at the time of taking out or storing a slide type terminal, As the stress due to the frictional force acting by the wide contact between the coil portions 7a and 7b of the coil-shaped elastic portion 7 accumulates, a crack is generated at the portion to be rubbed, thereby shortening the life of the spring 5. There is also a problem.

For example, since each of the coil parts 7a and 7b constituting the coil-shaped elastic portion 7 of the spring 5 is in wide contact with each other in the plane of the slide-out or storage operation, the strong frictional force acts. A lot of noise is generated, and furthermore, since the spring 5 burns out in a relatively short period due to the accumulation of such a strong frictional force, the life of the slide type terminal as well as the life of the spring 5 is shortened.

In addition, in the conventional spring 5 shown in Figs. 1 to 3, the coil-like elastic portion 7 is bent in the up and down direction as indicated by the arrow, especially when the slide-out or retracting operation is performed. As the phenomenon in which the 5 is bent in the up and down direction (the direction indicated by A in FIG. 3) occurs, the phenomenon that the spring 5 itself is scratched by the terminal during the withdrawal or storage operation of the slide type terminal is caused. Due to the phenomenon of scratching the terminal there is a disadvantage that also generates a lot of noise. Specifically, when the slide body of the slide-type terminal is taken out or stored, the spring 5 (particularly, the coil-shaped elastic portion 7 part) is scratched on the slide piece and the fixed piece, respectively, so that the slide body is stored or taken out. Inevitably, noise is generated.

In the case of the spring 5, the wire member 9 is connected to the coil-shaped elastic portion 7 in a straight line form so that each of the main parts of the spring 5 is bent and the coil-shaped elastic portion 7 The part where the wire rod part 9 continues (particularly, a part indicated by P in FIG. 2) also has a problem of being broken relatively easily, which causes a problem of shortening the life.

The present invention was developed to solve the problems as described above, the object of the present invention is the case that the noise is generated by the phenomenon that the main part of the spring friction during the slide-out operation of the slide body of the slide-type terminal It also prevents the occurrence of a lot of noise due to the phenomenon that the spring is scratched on the terminal, and further prevents the case of easily breaking the coil-type elastic part, which is the main part of the spring, and the subsequent part of the wire rod part, thereby improving product reliability. An object of the present invention is to provide an improved spring module of a slide type terminal.

According to the present invention for achieving the above object, in the slide type terminal is installed in the main body to open and close in the longitudinal direction, the slide body is switched to the state that is drawn out or received in one direction of the main body And a slide piece 20 coupled to the slide body, a fixed piece 10 coupled to the main body, and a spring 30 connected to the fixed piece 10 and the slide piece 20. The spring 30 is integrally connected to the coil-shaped elastic portion 32 and the coil-shaped elastic portion 32 of the snail shape in which the coil portions 32a and 32b are continuously connected to the fixing piece 10. And a pair of wire elastic parts 34 and 36 connected to the slide pieces 20 via hinge parts 34H and 36H, respectively, and the spring 30 gradually increases from an upper surface to a lower surface. Both sides Spring module of the slide-type terminal is provided, characterized in that configured in the cross-sectional form of the ordinary light lower narrowing width is gradually reduced between.

In the spring module of the slide type terminal according to the present invention, when the slide body is pushed upwards with respect to the main body to operate the slide piece to be pushed upwards with respect to the fixed piece, the slide body is opened about halfway with respect to the main body. The elastic member, which is a main part, has a structure in which a central portion to which a force is applied has a coil-shaped elastic part and a left and right wire elastic part formed in a snail shape, and the coil-shaped elastic part and the wire elastic part are formed on the upper surface. It is composed of the cross section of the ordinary light narrowing which gradually decreases the width between both sides toward the bottom, so that the contact frictional force is significantly reduced as the small-diameter coil portion and the large-diameter coil portion of the coil-shaped elastic portion are in point contact without contacting each other. Therefore, withdrawal operation of the slide body in the slide type terminal There is an advantage to prevent a lot of noise at the time of receiving the behavior.

In other words, in the related art, since each coil portion of the coil-shaped elastic portion is in surface contact with each other when the respective portions of the spring are bent, a large amount of noise may be generated during the withdrawal or storage operation of the slide type terminal. In the present invention, since the special structure is designed so that each coil part of the coil-shaped elastic part is point contacted in the spring, which is the main part, the area of contact of each coil part of the coil-shaped elastic part is minimized during drawing out or receiving of the slide body. In this case, a large amount of noise can be prevented due to a strong frictional force during spring operation, and a phenomenon in which a large amount of stress is accumulated due to a frictional force in which the coil portions of the coil-shaped elastic portion are in wide contact with each other is prevented. Even if cracks are generated in each friction part, it has an advantage of preventing in advance. have.

In addition, in the present invention, the wire elastic part of the spring is composed of a first wire elastic part and a second wire elastic part connected to both side portions of the coil-shaped elastic part, and the first inclined wire part and the second wire elastic part of the first wire elastic part. The inclined wire part is inclined in the vertical direction opposite to each other, and at the same time, the first ring part provided in the first connecting wire part and the second ring part provided in the second connecting wire part are also arranged to be shifted up and down, and the slide type terminal Each hinge portion connected to the slide piece of the slide body and the fixed piece of the main body of the slide body has a structure arranged in a position shifted up and down, so that both ends of the spring when the slide body of the slide type terminal is drawn out or stored Since the direction in which the first wire elastic part and the second wire elastic part receive the force are shifted from each other, especially in the spring, the coil-shaped elastic part is in the vertical direction. As the convex bend is prevented and the main part of the spring is not bent in the up and down direction (bending phenomenon), the spring itself is scratched by the terminal during the withdrawal or storage of the slide type terminal. It is also effective to prevent the case. When the slide body of the slide type terminal is pulled out or received, the main part of the spring (especially the coil type elastic portion) is convex up and down so that the slide pieces and the fixed piece of the slide type terminal are not scratched, respectively. This is to prevent the occurrence of noise inevitably during the storage or withdrawal operation.

In addition, the spring, which is the main part of the present invention, has a curved shape in which a wire elastic part connected to both ends of the coil type elastic part is not straight but smoothly continuous with a substantially circular coil type elastic part, and thus the slide body of the slide type terminal is drawn out. Due to the operation to be received, it is also possible to prevent the portions where the coil-shaped elastic portion and the wire elastic portion continue to break relatively easily when each main portion of the spring is bent, and furthermore, the portions where the coil-shaped elastic portion and the wire elastic portion continue. By effectively preventing the phenomenon of break in the spring it is possible to significantly extend the life of the spring compared to the conventional. This means that the reliability as a spring product can be significantly increased as compared with the conventional one.

The coil-shaped elastic portion 32 of the spring 30 is formed in a snail shape in which a small diameter coil portion 32a having a relatively small diameter and a large diameter coil portion 32b having a relatively large diameter are continuously formed, and a small diameter coil portion ( 32a) is comprised in the form accommodated in the inner position of the large diameter coil part 32b. Specifically, the first wire elastic portion 34 is continuously connected to one coil portion 32 on one side of the spring 30, and the second wire elastic portion 36 is connected to the other coil portion 32. ) Is formed in a continuous structure, the coil portion 32 has a structure in which the small diameter coil portion 32a is accommodated in the inner position of the large diameter coil portion 32b.

At this time, the spring 30 is configured in the cross-sectional form of the upper light lower narrowing gradually narrowing the width between both sides from the upper surface to the lower surface, this structure forms the most important feature in the present invention. In other words, the cross-section of the coil-shaped elastic portion 32 of the spring 30 and the cross-section of the pair of first wire elastic portion 34 and the second wire elastic portion 36 have an upper surface width relative to the bottom width. As a result, the larger and bilateral sides are composed of an inverted rhombus shape of a light beam lower slope inclined downward in a symmetrical direction.

At the same time, the elastic force is applied while the pair of first wire elastic parts 34 and the second wire elastic parts 36 integrated in both side ends of the coil type elastic part 32 are bent in a direction facing each other.

At this time, in the present invention, the spring 30 is configured in the cross-sectional form of the upper light lower narrowing in which the width between both sides gradually decreases from the upper surface to the lower surface, each of the small diameter coil portion 32a of the coil type elastic portion 32 Since the contact friction force is significantly reduced while the large-diameter coil portion 32b does not come into surface contact with each other without being in surface contact with each other, a large amount of noise is prevented from being generated when the slide body is pulled out or stored in the slide type terminal. There is an advantage.

As shown in Figs. 1 and 2, conventionally, since each coil portion 7a and 7b of the coil-shaped elastic portion 7 is in surface contact with a large area when each portion of the spring 5 is bent. In addition, in the present invention, a large amount of noise was generated during the withdrawal or storage operation of the slide-type terminal. The spring 30 operation is minimized by designing a special structure so that the coil contacts 32a and 32b of the coil-shaped elastic part 32 are contacted when the slide body is pulled out or stored. It is possible to prevent the occurrence of a lot of noise due to the strong frictional force at the time, and furthermore, a lot of stress is accumulated by the frictional force in which the coil portions 32a and 32b of the coil-shaped elastic portion 32 are in wide contact with each other. As the phenomenon is prevented, the spring 30 If a crack occurs in a portion in which each friction can be prevented.

In addition, in the present invention, the spring 30 is configured to have a first wire elastic part 34 and a second wire elastic part 36 connected to both sides of the coil type elastic part 32.

And a first inclined wire portion 34b extending inclined downward from an upper surface of the elastic portion 32 and a first connecting wire portion 34c extending horizontally following the first inclined wire portion 34b. .

The second wire elastic part 36 extends horizontally after being connected to the other side of the coil type elastic part 32, but has a second extension wire part 36a disposed below the first extension wire part 34a. And a second inclined wire portion extending from the bottom of the coil-shaped elastic portion 32 to be inclined upwardly and extending upwardly in the opposite direction to the first inclined wire portion 34b. 36b) and a second connecting wire portion 36c horizontally extending from the second inclined wire portion 36b.

Therefore, the first inclined wire portion 34b of the first wire elastic portion 34 and the second inclined wire portion 36b of the second wire elastic portion 36 have a shape inclined in the vertical direction opposite to each other. At the same time, the first ring portion 34d provided in the first connecting wire portion 34c and the second ring portion 36d provided in the second connecting wire portion 36c are also alternately arranged up and down, thereby sliding the slide type terminal.

As indicated by F), the phenomenon in which the coil-shaped elastic part 32 is convexly bent in the vertical direction in the spring 30 is prevented, and the phenomenon in which the spring 30 is bent in the up and down direction (bending phenomenon) As this does not occur, there is an effect of preventing the occurrence of noise by scratching the terminal when the spring 30 itself is pulled out or stored in the slide type terminal. Specifically, the spring 30 (particularly, the coil type elastic portion 32) is not scratched by the slide piece 20 and the fixed piece 10 when the slide body of the slide type terminal is drawn out or stored. In this case, noise is inevitably generated during the storage or withdrawal operation of the slide body.

In addition, the spring 30 is the first wire elastic portion 34 and the second wire elastic portion 36 connected to both ends of the coil-shaped elastic portion 32 of the linear rather than straight coil-shaped elastic portion 32 ) And smoothly curved surface shape. Specifically, the first wire elastic part 34 and the second wire elastic part 36 are configured in an arc shape which is continuous to the coil type elastic part 32.

Therefore, the portion where the coil-shaped elastic portion 32 and the wire elastic portions 34 and 36 are connected when each major portion of the spring 30 is bent due to the operation in which the slide body of the slide-type terminal is drawn out or received (particularly, 6 can be prevented from being broken relatively easily, and furthermore, by preventing the phenomenon in which the coiled elastic part 32 and the wire elastic parts 34 and 36 are broken in the subsequent part. Due to this has the advantage that can significantly extend the life of the spring (30).

On the other hand, Figure 10 and Figure 11 is another embodiment of the present invention, the first hinge piece 34B and the second hinge piece 36B at the ends of the left and right wire elastic parts 34 and 36 in the spring 30, respectively. There is a difference from the above embodiment in that it is provided. Since the rest of the configuration and effects are similar to the above embodiment, duplicate description thereof will be omitted.
