Description

[Detailed Description of the Invention] (a) Technical field to which the invention pertains This invention relates to a hook mechanism for fixing an electrical component or the like fitted into a socket with a hook.

(b) Prior Art and Its Disadvantages A conventional hook mechanism for fixing an electrical component fitted into a socket with a hook is shown in Fig. 1. Further, FIG. 2 shows a state in which the hook is engaged by this hook mechanism. A hook 3 used in this hook mechanism is attached to a hook groove 5 of the socket body 1. This attachment is carried out by press-fitting and inserting a pin 4 provided at the lower end of the hook 3 into a bearing portion 8 of the hook groove 5.
The hook 3 rotates around the pin 4, and when the tip of the claw portion 6 is hooked onto the hook portion 10 of the electrical component 9 fitted into the socket 2, the hook is engaged. When the handle 7 is pulled outward in this state, this hook engagement is released. When the hooks are not engaged, the hooks 3 are folded forward and stored in the hook storage portion 11 in order to prevent damage to the hook mechanism.

As described above, in the conventional hook mechanism, the hook 3 is supported at a certain distance from the socket 2 in order to form the hook storage section 11. However, since the pin 4 is press-fitted into the bearing part 8 and the fulcrum of the hook 3 is fixed, the hook 3
The socket cannot be moved in two directions. Therefore, in order to perform hook engagement, the hook portion 10 of the electrical component 9 must be extended to a position where it is hooked on the claw portion 6, which has the disadvantage of making the electrical component extra large. However, it could not be applied to small electrical parts that do not have such a hook part.

(c) Purpose of the invention The purpose of this invention is to provide a hook mechanism that can securely secure small electronic components and also allow the hook to be stored within the socket body.

(d) Structure and effect of the invention This idea can be summarized as follows.

A hook supporting pin consisting of an upper pin and a lower pin is provided on the hook body. In addition, the socket body has
A hook supporting recess is provided, and the hook supporting recess has a lower pin sliding surface on which the lower pin can slide horizontally, and an upper pin sliding surface that guides the movement of the upper pin as the lower pin moves. A pin guide surface is formed. A lower pin holding member is provided at a position inside the lower pin sliding surface. In such a hook mechanism, the state in which the lower pin is moved to the inner position of the lower pin sliding surface is held by the lower pin holding member. In this state, the hook engagement state between the hook and the electrical component disposed inside the socket main body is maintained. Further, when the lower pin is removed from the inner position of the lower pin sliding surface to the outside beyond the lower pin holding member, the hook can be stored in the removed state.

In this way, the lower pin can move horizontally along the lower pin sliding surface, and the hook engagement is performed with the lower pin moved to the inner position of the lower pin sliding surface, and the lower pin is moved outward from the inner position. Store the hook with the lower pin moved.

According to this invention, the inner position of the lower pin sliding surface can be provided close to the socket, so there is no need to provide an extra hook part on the side of the electrical component, and small electrical components can be attached. can be securely fixed. Therefore, there is no need to provide an extra hook, which has the advantage of contributing to cost reduction of electrical components. Further, since the hook can be stored by moving the lower pin outward from the inner position, a practical and compact hook mechanism can be obtained.

(e) Description of the embodiment Figure 3 shows the hook 20 used in the embodiment of this invention.
FIG. 4 is a sectional view showing a state in which the hook is engaged by the hook mechanism of the same embodiment. The hook 20 is provided with a "F"-shaped claw portion 23, and a hook supporting pin consisting of an upper pin 22 and a lower pin 21 is provided at the lower part of the hook body. The upper pin 22 and the lower pin 21 are fitted into a hook supporting recess 25 formed inside the socket body 28. The hook supporting recess 25 has a lower pin sliding surface 27 on which the lower pin 21 can move horizontally, and a lower pin sliding surface 27 as shown in FIG.
It has upper pin guide surfaces indicated by b, c, d, and e that guide the movement of the upper pin 22 as the lower pin 21 moves. The front end of the lower pin sliding surface 27 is located approximately at the side end of the electrical component 30 fitted into the socket 29. As shown in FIG. 4, at the inner position of the lower pin sliding surface 27 where the side surface of the lower pin 21 reaches the front end of the lower pin sliding surface 27, the tip of the claw portion 23 hooks the electrical component 30. 31. If the claw part 23 is short, the lower pin sliding surface 2
The front end of the electrical component 7 may be disposed deeper than the side end of the electrical component 30. When the hook 20 is engaged with the electrical component 30, the lower pin 21 is attached to the lower pin sliding surface 2.
A lower pin holding member 26 that protrudes from the lower pin 7 and has a triangular cross section holds the lower pin at a position inside the lower pin sliding surface 27 . Further, the lower pin sliding surface 27 is formed of an elastic body and can be displaced downward about a fulcrum provided on the outside. And lower pin sliding surface 2
7 has a horizontal length that allows the lower pin 21 to move to a position where the hook 20 can be laid down laterally and stored in the hook storage section 32 in the socket body 28. When storing the hook 20 in the hook storage portion 32, the hook engagement is released by pulling outward the handle 24 provided at the top of the hook body perpendicular to the claw portion 23, and the hook can be further pushed forward. This is done by

Next, the operation of this hook mechanism will be explained with reference to FIG.

Figure A shows the hook storage state. In this state, the side surface of the lower pin 21 has reached the rear end of the lower pin sliding surface 27. In order to engage the hook, the handle 24 is pulled upward from this hook storage state. At this time, as shown in FIG. B, the hook 20 rotates about the center of the lower pin 21 as a fulcrum,
As the upper pin 22 rotates, it begins to come into contact with the upper pin guide surface and moves upward along the upper pin guide surface. As the upper pin 22 moves upward, the lower pin 21 also gradually slides forward along the lower pin sliding surface 27. As the handle 24 is further pushed down, the line connecting the centers of the upper pin 22 and the lower pin 21 becomes perpendicular to the lower pin sliding surface 27, as shown in FIG. The hook 20 rotates with the center of the upper pin 22 serving as a fulcrum. When the handle 24 is pushed down in the state shown in C in the figure, the lower pin sliding surface 27 that contacts the lower pin 21 is pushed down as it rotates around the upper pin 22, so the lower pin 21 holds the lower pin. Part 2
6 and reach the inner position of the lower pin sliding surface 27. The state in which the lower pin 21 has reached this inner position is shown in FIG. When the handle 24 is pulled forward as shown in FIG. The hook 20 is raised to a position where a line connecting the centers of the upper pin 22 and the lower pin 21 is perpendicular to the lower pin sliding surface 27. In this state, as described above with reference to FIG. 4, the claw portion 23 engages with the hook portion 31 of the electrical component 30 fitted into the socket 29. As mentioned above, the lower pin 21 is attached to the lower pin holding member 2.
Since the handle 24 is held in the inner position by the handle 6, this hook engagement state is maintained unless a large external force is applied outward to the handle 24. Furthermore, since the position of the lower pin 21 when the hook is engaged can be formed close to the socket 29, the electrical component 30 can be positioned close to the socket 29.
Reliable hook engagement can be achieved simply by providing a small hook portion without forming an extra hook portion extending outward. Therefore, it is possible to engage small electric parts with the hook, and the cost of the electric parts is reduced by not forming an extra hook part.

Next, this hook storage operation will be explained.

As shown in FIG. 5E, when the handle 24 is first pushed forward, the upper pin 22 rotates and comes into contact with the upper pin guide surface. Further, when the handle 24 is pushed forward, the hook 20 rotates around the upper pin 22, so that the lower pin sliding surface 27 that contacts the lower pin 21 is pushed down. Therefore, the lower pin 21 can pass over the lower pin holding member 26 and move from the inner position of the lower pin sliding surface 27. The state during this movement is shown in FIG. 5F. When the hook 20 is further moved outward from this state, the lower pin 21 reaches the rear end of the lower pin sliding surface 27, as shown in FIG. 5G.
Then, when the handle 24 is pushed down, the hook 20
rotates around the lower pin 21 to open the hook storage section 32.
is stored in. As described above, hook engagement and storage are easily and reliably performed.

Next, another embodiment of this invention will be described.

FIG. 6 is a diagram showing the vicinity of the hook supporting recess 40 of a hook mechanism according to another embodiment. The other hook mechanism members are the same as in the previous embodiment, and their explanation will be omitted. This hook supporting recess 40 is the same as the hook supporting recess 25 of the previous embodiment. In this hook mechanism, two lower pin holding members 41 and 42 are provided inside the lower pin sliding surface 43 with a pitch equal to the outer diameter of the lower pin. By providing the two lower pin holding members 41 in this manner, two types of electrical components having different external shapes can be hooked together using one hook mechanism. That is, one kind of electrical component can be engaged with the hook while the lower pin is held at the inner position 44 beyond the lower pin holding member 41, and the lower pin holding members 41 and 4 can be hooked together.
With the lower pin held at the inner position 45 between the inner position 45 and the inner position 45, an electrical component larger than the electrical component hooked at the inner position 45 can be engaged with the hook. Note that, similarly to the embodiment described above, the lower pin moves to the rear end of the lower pin sliding surface 43 and the hook is stored.
