Abstract

PURPOSE:To fit connectors in first and second cases mutually and easily without requiring a guide pin, etc., by temporarily positioning a second unit at a first location projected partially from the first case and fixing the second unit at a second pushed location. CONSTITUTION:A unit 11 is inserted into a lower case 10, and positioned temporarily at a location where the side bottom edge section of the unit 11 is abutted against a protrusion 13. A unit 21 is inserted forcibly into an upper case 20, and the case 20 is opened slightly and the unit 21 is fastened temporarily at a specified position exceeding the protrusion 23. When a connector hole 22a is conformed to a connector pin 12a, the unit 11 is projected partially to the upper section of the case 10, thus easily positioning and fitting the connectors 11, 21. The lower case 10 is held by one hand and the upper case 20 by the other hand, and the lower case 10 is detached from the upper case 20. Since slip-off force from the hole 22a of the pin 12a is made smaller than slip-off force from the protrusion 13 of a recessed section 14, the unit 11 is left at a lower location as it is left as it is fitted to the protrusion 13.

[Industrial application field]

The present invention relates to a simple and compact housing structure such as a terminal of an electronic/communication device, a terminal of a portable radio device, a handset of a telephone, etc., particularly a first case housing a first unit therein, and a second unit inside the case. The present invention relates to a two-part housing structure in which a first connector of the first unit and a second connector of the second unit are fitted to each other at the same time as a second case housing the first unit is connected to the second case.゛When combining small cases divided into two in this way and simultaneously connecting each unit with connectors, if both connectors, that is, male and female connectors, are inside the unit at the time of combining, It is difficult to connect the connector because the connector part to be connected cannot be seen sufficiently. Therefore, it is required to easily and inexpensively realize such connections between cases and between units.

[Conventional technology]

Conventionally, a two-part case, for example, a case structure of a telephone handset, combines a lower case 1 having a receiving and transmitting part (not shown) and an upper case 2, as shown in FIG. A unit 4 is temporarily fixed inside the lower case 1 by a projection 3, and a male connector 5 is attached to the unit 4.

On the other hand, a unit 7 is temporarily fixed inside the upper case 2 by a projection 6, and a female connector 8 is attached to the unit 7.

When joining upper case 2 to lower case 1, unit 4
The fitting part between the male connector 5 of the unit 7 and the female connector 8 of the unit 7 is located inside the case 1.2, and these connectors 5.8 are visually inspected through the gap 9 of the case 1.2. It is not possible to align the Therefore, a plurality of guide pins 8a for alignment are provided in one unit 7, and a plurality of guide holes 5a corresponding to these guide pins 8 are provided in the other unit 4. As a result, when joining the upper case 2 to the lower case 1, there is no need to look at the connector part through the gap 9 of the case 1.2, and by aligning the guide pin 8 with the guide hole 5a and joining both cases 1.2. good.

[Problem to be solved by the invention]

However, according to the conventional structure as shown in FIG. 5, extra space is required for the guide pin 8a and guide hole 8a, and an increase in the number of parts for this purpose is required. Therefore, it is unsuitable for small devices with limited component space. Therefore, in order to avoid such extra space, it is necessary not to use the guide pin 8a, etc., but to insert both connectors during the assembly work of the unit, which causes the problem of poor work efficiency. be.

Therefore, the present invention does not require special means such as guide pins or guide holes, and therefore does not require extra space, and moreover, when connecting both cases, the connectors in both cases can be connected simultaneously and easily. 2 that can fit together
The purpose is to obtain a split type housing structure.

[Failure to solve the problem]

In order to solve such problems, according to the present invention, a first case housing a first unit therein and a second case housing a second unit inside are combined, and at the same time,
In the two-part housing structure in which the first connector of the first unit and the second connector of the second unit are fitted to each other, the first case and/or the first unit means for temporarily positioning the unit in a first position at least partially protruding from the first case;
means for fixing the first unit at a second position inside the first case, and when the first case and the second case are coupled, the first unit is temporarily positioned at the first position. The first unit in the first position is temporarily positioned by aligning the first connector and the second connector in the state and forcing the second case toward the first case after the alignment. When moving over the means to the second position and separating the second case from the first case, the first unit in the second position is stopped at the second position without overcoming the fixing means. A two-part casing structure is provided, which is characterized in that it is configured in such a manner that

[For production]

Before joining both cases, the first unit is temporarily fixed in the first position. In this position, since the first unit at least partially protrudes from the first case, the two connectors can be easily aligned and fitted. After the alignment is completed, by forcing the second case toward the first case, the second connector pushes the first unit inward of the first case via the first connector, and the first unit moves to the temporary positioning means. , and moves to the second position, where it is fixed. On the other hand, when the second case is separated from the first case, the first unit remains at the second position without climbing over the fixing means. Therefore, the connectors can be easily separated from each other.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of a two-part housing structure according to the present invention, and FIG.
The figure is a cross-sectional view taken along line A-A' in Figure 1, and Figure 3 is a cross-sectional view taken along line A-A' in Figure 1.
A sectional view taken along line BB' shows the state before assembly,
FIG. 4 is a sectional view taken along the first line BB', but shows the state after assembly.

The two-part housing according to the present invention, for example, the housing structure of a telephone receiver, includes a lower (first) case 10 having a receiving/receiving part (not shown) and an upper (second) case 20. Consisting of

These cases 10, 20 are molded from a suitable resin such as polycarbonate, and have appropriate elasticity. A first unit 11 is housed inside the lower case 10, a second unit 21 is housed inside the upper case 20,
These units 11 and 21 are equipped with various electronic components (not shown), and various electronic circuits (not shown) are formed therein.
A connector 12 is fixed, and a second (female type) connector 22 corresponding to this connector 12 is fixed to the unit 21. Further, the two units 11.21 are connected to each other by a cord 25.

The lower case 10 has means for fixing or temporarily fixing the unit 11 at two positions. That is, the lower case 10 has a protrusion 13 on one inner wall, the bottom edge of the unit 11 on one side is in contact with this protrusion 13 (Fig. 3), and the other side of the unit 11 is in contact with the protrusion 13 on the other side. is lightly pressed against the inner wall surface of
The unit 11 is temporarily fixed at the upper (first) position where it partially protrudes from the lower case 10. Of course, lower case 1
0 may be configured to provide a protrusion similar to the protrusion 13 on the other inner wall surface so as to receive the bottom edge of the other side of the unit 11.

Further, a recess 14 is provided on one side of the unit 11,
When this unit 11 is pushed downward into the lower case 10 past the protrusion 13, the recess 14 comes to the position where it fits into the protrusion 13 and is fixed at the second position (fourth position).
figure). By forcing the unit 11 downward, the protrusion 1
Of course, the reason why the lower case 10 can be moved downward by more than 3 is by utilizing the elasticity of the lower case 10 itself.

On the other hand, the upper case 20 has projections 23 on both inner walls, and temporarily fixes the unit 21 at one predetermined position. In this case as well, by forcing the unit 21 into the upper case 20, the unit 21 is
is inserted beyond the protrusion 23 and temporarily fixed in a predetermined position.

When combining the lower case 10 and the upper case 20,
First, after assembling the units 11 and 21 separately, they are connected with the cable 25. Then, the unit 11 is inserted into the lower case 10 and temporarily positioned at a position where one bottom edge of the unit 11 comes into contact with the protrusion 13.

On the other hand, the unit 21 is forcibly inserted into the upper case 20, the upper case 20 is slightly opened, and the unit 21 is temporarily fixed at a predetermined position beyond the protrusion 23.

Next, hold the lower case 10 with one hand, hold the upper case 20 with the other hand, and move the upper case 20 to the lower case 10.
, and align the connector hole 22a of the female connector 22 of the unit 21 with the connector pin 12a of the male connector 12 of the unit 11. At this time, since the unit 11 is partially protruding from the upper part of the lower case 10, the connectors 11 and 21 can be easily aligned and fitted together.

Next, when the upper case 20 is forcibly pushed down toward the lower case 10, the upper case 20 is bent to open slightly, the unit 11 is pushed into the lower case 10 over the protrusion 13, and the recess 14 is inserted into the protrusion 10. The unit 11 is fixed in the fitted position, and the fitting between the connectors 12 and 22 is completed. In this operation, lower case 1
By slightly opening the hand holding the 0, the unit 11 can smoothly move over the protrusion 13. The temporary connection between the upper case 20 and the lower case 10 is performed by a well-known means (not shown), for example, by mutually fitting claws and holes, and the upper case 20 and the lower case 10 and the unit 11 between them are .21 is finally fixed with a bolt (not shown) passing through.

When separating the upper case 20 from the lower case 10, after removing the bolts (not shown) as mentioned above, hold the lower case 10 with one hand and pull the upper case 20 with the other hand.
, and pull the upper case 20 away from the upper case 10. At this time, the connector pin 12a of the male connector 12
Since the force with which the unit 11 is removed from the connector hole 22a of the female connector 22 is smaller than the force with which the recess 14 of the second knit 11 is removed from the protrusion 13, the recess 14 of the unit 11 remains fitted into the protrusion 13, and the unit 11 is removed from the lower part ( 2) Stay in position. In this operation, if the hand holding the lower case 10 is slightly closed, the unit 11 will not climb over the protrusion 13 and will surely remain at the lower position.

After separating the upper case 20 from the lower case 10 in this manner, the respective unit 11.21 is removed from each case 10.20.

〔Effect of the invention〕

As described above, according to the present invention, there is no need for special means such as guide pins and guide holes unlike the conventional two-part housing structure, so there is no need for special space associated with these. This will lead to high-density component mounting. Moreover, the two cases can be connected extremely easily, and the connectors can be reliably fitted with a simple operation.
