Description

Specification

Contact for movable connector and movable connector using the same

The present invention relates to a movable connector having a floating structure capable of absorbing a displacement with respect to a mating connector, and a contact therefor, which is an electrical connector mounted in an H-connection. Background art

In the case of an electronic β such as a digital camera, a plurality of substrates S are housed in a housing in a state of being connected via a connector. A pair of H¾l pairs is linked via two or more connectors: ^, etc., where the position of the connector pair inevitably occurs between a pair of 1HH¾I pairs: ^. If the connector is misaligned, stress will be applied to each connector. If the connector is used as it is, the connector leads (solder-attached part) may be peeled off from the wiring board, resulting in poor conduction. Leads to.

Therefore, in order to absorb the displacement of the connector between the connectors to be interconnected, an awake connector as shown in Japanese Patent Application Laid-Open No. 6-325825 is used. The movable connector has a fixed housing that is fixed on the contrary, and a movable housing that is mounted in a movable state (floating state) with respect to the fixed housing. The fixed housing has a report, for example, and the movable housing is loosely fitted in the fixed housing. The movable housing is attached to the fixed housing via several connections for electrical connection; the elastic deformation of the contacts allows the movable housing to be displaced with respect to the fixed housing. The misalignment with the side connector is absorbed. The contact is provided with a lead portion for soldering to the wiring opposite to the wiring in the fixed housing. By soldering the lead portion to the contact, the electrical connection between the contact and the contact is made. In order to prevent the concentration of stress on the lead, it is usually necessary to fix the fixed housing in place! A metal tab is provided so that the metal tab is soldered to the wiring si. Efficiency has also been reduced with the miniaturization of electrons such as β. Therefore, miniaturization of connectors is indispensable for mounting a large number of electric and electronic components on the mounting surface with a limited area on the small wiring si.

In order to reduce the size of the movable connector, it is preferable to minimize the clearance between the fixed and the housing and the movable housing as much as possible.

However, when the clearance between the two housings is reduced, the length of the contact between the fixed housing and the movable housing is shortened.Accordingly, the displacement of the movable housing and the housing is reduced, and the displacement between the connectors is reduced. May not be absorbed properly. Disclosure of the invention

An object of the present invention is to provide a movable connector contact and a movable connector using the same, which can reduce the size of the connector while ensuring a sufficient change of the movable nozzle.

The contact for a movable connector according to the present invention may have a fixed housing (10) fixed to the wiring and a movable housing (20) displaceably coupled to the fixed housing. The contact (30) to be attached to the connector, which is connected to the movable housing and connected to the movable housing (¾32), and the fixed housing side connected to the fixed housing (! 3). A snake connecting portion (33) for connecting the movable housing side and the fixed housing side, and a contact portion (35) provided on the movable housing side for electrical connection with a mating connector. And a lead portion (34) provided on the fixed housing side for soldering to a wiring arrangement. Note that the alphanumeric characters in parentheses indicate the corresponding constituent elements and the like in the state described later, but this is not intended to be construed as an example of the present invention. The same applies hereinafter in this section.

It is preferable that the connecting portion of the snake has two or more peaks. The movable connector according to the present invention includes a fixed housing fixed to the arrangement, a movable housing displaceable with respect to the fixed housing and the housing, and a movable housing displaced relative to the fixed housing and the housing. Connect as possible, and connect with the other party Includes the above-mentioned contact for electrically connecting between the wiring and the wiring.

According to these configurations, the movable housing side ^ and the fixed housing side! And ^^ are connected via a meandering connection (preferably having two or more peaks), so even if the clearance between the movable housing and the fixed housing is small, the connection Can be made sufficiently long. This makes it possible to secure a sufficient amount of displacement of the movable housing while reducing the clearance to reduce the size of the movable connector, thereby facilitating the absorption of the displacement between the movable connector and the mating connector.

Assuming that the connecting portion of the meandering is a single mountain, the height of the mountain must be considerably high in order to secure a considerable amount of deflection, and the connecting portion protrudes greatly from the housing. As a result, the contact exposure is increased. Therefore, if the connection part of 狱 is formed with two or more peaks, a considerable amount of deflection can be secured even if the height of the peak is low, the contact does not protrude greatly from the housing, and the exposure of the contact is reduced. .

The above and other objects, features, and effects of the present invention will become apparent from the following description of embodiments with reference to the accompanying drawings.

FIGS. 6 (a), 6 (c) and 6 (d) are views for explaining the manufacturing process of the movable connector. More specifically, FIG. 6 (a) is a plan view of one molded product 50 of the fixed nozzle 10 and the movable nozzle 20 and FIG. 6 (b) is a front view thereof, and FIG. c) is a bottom view, and FIG. 6 (d) is a right side view.

This integrally molded product 50 is made of a movable housing 20, a pair of contact fixing portions 11 arranged along both sides of the movable housing 20, and a pair of discarded housings 60 integrally separated by a resin material. It was done. The pair of disposable housings 60 couples both ends of the movable housing 20 and the pair of contact fixing members 1 respectively. More specifically, the disposable housing 60 includes a main body 65 along both end surfaces of the contact fixing portion 11 and an end surface of the pair of contact fixing portions 11 And a pair of fixed housing connecting legs 6 1, 6 2 extending parallel to the surface of the movable housing 20 and an end surface of the movable housing 20 (the surface of the retaining projection 26). And connecting legs 63.

The fixed housing connecting legs 6 1 and 6 2 are connected to the surface (contactor) (See FIG. 1 (d) and FIG. 2). In addition, the movable housing ^ r leg portion 63 is provided with a disposable housing connecting portion 27 (see FIG. 1 (d)) on the surface of the retaining projection 26 of the movable housing 20 (the surface orthogonal to the longitudinal direction of the movable housing 20). ) And Fig. 2 together.

On the corresponding end faces of the movable housing 20 and the pair of contact fixing portions 11, the waste housing thread portions 27 and 16 are in the same plane (a plane orthogonal to the longitudinal direction of the movable housing and the contact fixing portion 11). ). For this reason, the separation between the discarded housing connection l6, 27 and the housing ^^ legs 61, 62, 63 can be performed collectively using cutting ^.

FIG. 7 is a flowchart for explaining i¾i: rf presentation of the movable connector. First, the pair of contact fixing portions 11 and the movable housing 20 are discarded, and the integrally molded product 50 joined by the housing 60 is β¾Β with a resin material (step SI) ο

Next, the reinforcing tabs 40 are press-fitted into the reinforcing tab fixing portions 13 at both ends so as to bridge the pair of contact fixing portions 11, thereby connecting the pair of contact fixing portions 11 (step S 2). At this time, as shown in FIG. 1 (d) and FIG. 2, the discarded housing connection 27 of the movable housing 20 is exposed in the direction of the end face from the arched portion of the reinforcing tab 40, and Each of the contact fixing portion 11 and the disposable housing connecting portions 16 and 27 of the movable housing 20 are located on the outer side in the longitudinal direction of the reinforcing tab 40 with respect to each longitudinal direction.

Thus, after the reinforcing tab 40 is attached, the plurality of contacts 30 are implanted so as to bridge the contact fixing portion 11 and the movable housing 20 (Step S3).

Thereafter, by using a cutting instrument, the throw-away housing 60 is separated from the contact fixing portion 11 and the movable housing 20 cut off at the throw-away housings 16 and 27 (step S4). As a result, the movable housing 20 can be displaced relative to the fixed housing 10 within a permissible range due to the clearance between the two and the elastic deformation of the contact 30. 0 is completed. As described above, according to this configuration, the movable housing 20 and the pair of contact fixing portions 11 are integrated with each other via the pair of discarding housings 60, so that the clearance between them is provided. Can be set small so that the size of the movable connector 100 can be reduced. Moreover, since the pair of disposal housings 60 joins both ends of the movable housing 20 and the contact fixing portion 11, the amount of the cut residue at the time of the cut is very small, and the cut residue is the contact. It hardly reaches near 30. Since the movable housing 20 and the contact fixing portion 11 are not provided with! ^ Except for the disposal housing 60, there is a possibility that defective soldering of the contacts 30 due to the cutting residue may occur. Absent.

In addition, since the contact 30 has the connection part 33 of 狱, although the clearance between the movable housing 20 and the connection fixing part 11 is minimized, the contact A sufficient amount of deformation can be ensured, and the positional deviation from the mating connector 5 can be well absorbed.

Further, since the fixed housing 10 is reinforced by the reinforcing lugs 40 bridging the pair of contact fixing portions 11, the contact fixing portions 11 can be formed to be thin. Further miniaturization of the movable connector 100 has been approved.

As described above, the embodiments of the present invention have been described, but the present invention can be made in other forms. For example, in the above state, a pair of contact fixing portions 11, a movable housing 20 and a discarding housing 60 are integrated.) After manufacturing the product 50, the reinforcing tab 40 is press-fitted. In a state where the reinforcing tabs 40 are inserted into the pair of contact fixing portions 11, a product may be manufactured in which the reinforcing tabs 40 are inserted. The process of Steps S 1 and S 2 in Step 7 may be performed instead.

Further, in the above-described embodiment, the pair of contact fixing portions 11 and the movable housing 20 are combined at the both ends by the disposal housings 60. However, the pair of contact fixing portions 11 and the movable housing 2 0 may be combined with the disposal housing 60 only at the corresponding one end.

Further, in the above state, the fixed housing 10 is a pair of separated housings. Although the contact housing 11 has a fixed contact 11, the pair of contact housings 11 may be separated from each other at a location other than the discard housing 60, and the fixed housing 10 may be formed as a single component. .

Also, in the above difficult embodiment, a 20-pin type movable connector provided with 20 contacts 30 has been described. However, the number of pins is only an example, and for example, by increasing the length, 4 A movable connector having an arbitrary number of pins such as a 0-pin type or an 80-pin type can be configured.

Although the embodiments of the present invention have been described in detail, these are only specific examples used for clarifying the technical contents of the present invention, and the present invention is interpreted by limiting to these specific examples. The spirit and scope of the present invention should be limited only by the appended claims.

This application corresponds to Japanese Patent Application No. 2003-1361 filed with the Japan Patent Office on January 7, 2003, and the entire disclosure of this application is hereby incorporated by reference. It shall be incorporated by use.
