Description

Socket, Metal Part and Latch Structure {SOCKET, METAL PART AND LATCH}

The present invention provides a socket for forming a storage space for accommodating an insert such as a camera module, a metal part for defining the storage space, and an insertion provided in the socket or the metal part. A latch structure for hanging an object such as a sieve.

Conventionally, the socket which accommodates inserts, such as a camera module, is required to be downsized. As an example of a technique for solving this problem, Patent Literature 1 integrates parts such as a contact or an insulator to form a socket 1 as a single part, and simplifies the assembly process by reducing the number of parts. It is described that the formation, the low cost, and the low magnification are achieved. The socket 1 has a rectangular frame shape in which a metal sheet is pressed to form an accommodating portion 1d. The socket 1 is bent by inserting cuts on both left and right sides thereof. A pair of coupling springs 1b are formed. The camera module 2 accommodated in the socket 1 is provided with a rectangular groove portion 2b which faces downward from both upper corner portions of the left and right side surfaces thereof. The engaging spring 1b is caught by the groove 2b while the camera module 2 is inserted into the receiving portion 1d of the socket 1, thereby preventing the camera module 2 from being separated from the socket 1. Configure the latch structure.

Japanese Patent Laid-Open No. 2008-016419 (paragraphs 0020, 0021, 0027, Figs. 4 to 7)

In the case of accommodating the camera module 2 in the accommodation portion 1d of the socket 1 as described above, first, each coupling spring 1b is pushed to the side of the camera module 2 to the accommodation portion 1d. It is elastically displaced in the outward direction. When the camera module 2 is deeply inserted into the receiving portion 1d, each of the coupling springs 1b tries to return to the inner side of the receiving portion 1d by the spring property thereof, so that the camera module 2 It is inserted into each groove part 2b of a. As a result, the coupling spring 1b and the groove 2b are engaged so that the camera module 2 does not leave the socket 1.

Since the height of the socket 1 described in Patent Document 1 is at least the length of the coupling spring 1b, when the socket 1 is made low, the coupling spring 1b is also shortened. However, when the coupling spring 1b is shortened, the spring property of the coupling spring 1b becomes small, so that it is difficult to elastically displace, so that the camera module 2 cannot be accommodated in the socket 1.

An object of the present invention is to miniaturize a socket while elastically deforming and securing the spring property of the spring portion to allow the insertion of the insert into the socket, thereby preventing the insertion of the insert.

The socket of the present invention is formed of a metal plate, has a tubular shape, has an opening, and includes a receiving portion for forming a receiving space for receiving an insert inserted from the opening. And a hole formed in the metal plate without being separated from the metal plate, and from the edge toward the inside along the rolled surface of the metal plate in a direction crossing the edge of the metal plate forming the opening. A spring portion extending in a tongue shape, the front end side region is bent, protrudes from the rolled surface of the metal plate to the receiving space side, and is caught by the insert housed in the receiving space; It extends from the base side of the said spring part, the one side side is the said edge, and the other The side surface of the method is provided with the connection part formed in parallel with the said edge by the said hole part.

The metal part of the present invention is formed without forming a hole in a metal plate defining an accommodation space for accommodating an inserted insert, without separating from the metal plate, and rolling the metal plate from the edge in a direction crossing the edge of the metal plate. It extends in the shape of the tongue toward the inside along the surface, the front end side region is bent to project from the rolled surface of the metal plate to the receiving space side, and slide along the rolled surface of the metal plate from the edge toward the receiving space side And a spring portion caught by the insert accommodated in the accommodation space, extending from a base side of the spring portion, one side edge being the edge, and the other side edge being formed in parallel with the edge by the hole. .

The latch structure of the present invention is formed without forming a hole in the metal plate to separate it from the metal plate, and extends in a tongue shape from the edge toward the inside along the rolling surface of the metal plate in a direction crossing the edge of the metal plate, A front end side region is bent to protrude from a rolling surface of the metal plate, and extends from the base side of the spring part, one side of the edge is the edge, and the other side of the edge is formed in parallel with the edge by the hole. It is provided with a connecting portion.

According to the present invention, as the spring portion is elastically displaced, the connecting portion extending from the base side of the spring portion is also twisted. For this reason, even if a spring part is shortened, sufficient spring property is ensured by the torsional elasticity of a connection part. Accordingly, the socket can be miniaturized while elastically deformed to allow the insertion of the insert into the socket, thereby securing the spring property of the spring portion to prevent the insertion of the insert after insertion.

One example in the practice of the present invention will be described with reference to Figs. For convenience of explanation, this embodiment is called a first embodiment. This embodiment is an example applied to a camera module socket. 1 is a perspective view of a socket 101 (camera module socket). 2A is a rear view of the socket 101. 2B is a left side view of the socket 101. FIG. 2C is a plan view of the socket 101. FIG. 2 (d) is a right side view of the socket 101. 2E is a bottom view of the socket 101. 2 (f) is a front view of the socket 101. FIG.

The socket 101 has a socket housing 102 as a receptacle. The side wall 102a of this socket housing 102 is formed by press working a board-shaped metal member, forming a hole 109, and bending. The side wall 102a has a cylindrical shape so as to form a rectangular parallelepiped receiving space 121, the upper surface of which is an opening 121a, and a plurality of contacts on the bottom surface thereof. 103 is disposed. From the opening 121a, the camera module 301 (refer FIG. 4 (a)-FIG. 4 (c)) as an insert is inserted, and is accommodated in the accommodation space 121. As shown in FIG. The camera module 301 is formed with a rectangular cutout portion 302 (see Figs. 4 (b) and 4 (c)) downward from the upper edge portion of the side surface thereof.

The contact 103 is formed by pressing a metal plate having a spring property and bending a portion thereof, and is seen as a long rectangular shape in plan view. In this contact 103, the contact part 104 extends in the inner direction of this contact 103 from the one end part. The contact portion 104 is bent from the bottom of the socket housing 102 toward the opening 121a side of the socket housing 102 to stand. Moreover, the board | substrate connection part 105 protrudes from the other end of the contact 103. The board connecting portion 105 protrudes outward from the side wall 102a of the socket housing 102 and is soldered to an electronic circuit board (not shown) of an electronic device located on the side of the socket 101. Is fixed. On the bottom of the socket 101, the contact 103 forms two rows of contact rows 103a arranged in rows so that their long sides face each other. The socket housing 102 and the contact 103 and the contact 103 are fixed to each other by a resin 151. More specifically, the resin 151 liquefied by heat melting is injected into the space between the socket housing 102 and the contact 103 and between the contacts 103. do. As the resin 151 is cured, the positional relationship between the socket housing 102 and the contact 103 and the positional relationship between the contacts 103 are fixed.

3A is an enlarged perspective view of a part of the socket 101. FIG. Fig. 3 (b) is a view seen from the arrow A of Fig. 3 (a). A first latch 106 is formed in each of the two side walls 102a facing in the socket housing 102. In the socket housing 102, a second latch 107 is formed on each side wall 102a. In the present embodiment, the first latch 106 corresponds to the "spring portion" in the claims.

Both the first latch 106 and the second latch 107 are formed without forming a hole 109 in the side wall 102a without being separated from the side wall 102a, and have a tongue shape. It is. Both of the first latch 106 and the second latch 107 intersect the edge 102ab of the side wall 102a forming the opening 121a, and the side wall 102a including the edge 102ab. It extends downward from the upper edge part 102aa of (), and extends inward along the rolling surface of the side wall 102a. The first latch 106 and the second latch 107 are also bent toward the storage space 121 side in the vicinity of the upper edge portion 102aa. Further, the first latch 106 and the second latch 107 are also formed by bending the tip side region (the region of the lower portion of the first latch 106 or the second latch 107) toward the side wall 102a. The prevention part 108 is provided.

The connection part 110 is extended from the upper edge part 102aa side (base side) of the 1st latch 106. The connecting portion 110 is a horizontally long portion extending along the edge 102ab of the socket housing 102. The upper side in the connection part 110 is formed by the edge 102ab of the socket housing 102. The lower side of the connection portion 110 is formed in parallel with the edge 102ab of the socket housing 102 by the hole portion 109. It is preferable that the lower side of the connection part 110 extends in parallel with the edge 102ab of the socket housing 102.

By the way, the recessed part 111 is formed in the part located above the 1st latch 106 in the edge 102ab of the socket housing 102. As shown in FIG. The recessed part 111 is recessed downward from the edge 102ab of the socket housing 102, and toward the inner side along the rolling surface of the socket housing 102 in the 1st latch 106 rather than the connection part 110. As shown in FIG. It is shaped like a V to go deep. And the lowest point 112 of the recess 111 is located on the center line 113 of the first latch 106.

4 (a) to 4 (c) show the movement of the first latch 106 when the camera module 301 is inserted into the accommodation space 121 of the socket housing 102, and FIG. 3 (b). Is a cross-sectional view taken along line BB. When the camera module 301 is inserted into the accommodation space 121 of the socket 101 configured as described above, the camera module 301 is located in the opening 121a of the socket housing 102, and the socket is as it is. It moves toward the bottom face of the housing 102 (see Fig. 1) (Fig. 4 (a)). The lower part of the camera module 301 presses the 1st latch 106 to the outer side with respect to the accommodation space 121 in the middle of this movement. As a result, the first latch 106 is elastically displaced outward with respect to the accommodation space 121, as shown in Fig. 4B. Importantly, since the connecting portion 110 is formed to be horizontally long, the connecting portion 110 is twisted in the direction S according to the elastic displacement of the first latch 106.

If the camera module 301 moves further downward in the state shown in Fig. 4B, the connecting portion 110 is opposite to the direction S by the torsional elasticity S '. The first latch 106 is inserted into the cutout portion 302 of the camera module 301 to return to the receiving space 121 side by its spring property (Fig. 4 (c)). As a result, the fall prevention part 108 of the first latch 106 and the cutout part 302 of the camera module 301 are coupled so that the camera module 301 does not leave the socket 101.

As described above, in the socket 101 of the present embodiment, the connection part 110 is formed so that the connection part 110 is twisted as the first latch 106 elastically displaces. That is, the overall spring property of the first latch 106 is increased by the connecting portion 110. Therefore, even if the first latch 106 is shortened, sufficient springability is ensured even when the camera module 301 is deformed when inserted into the accommodation space 121. Therefore, the socket 101 is elastically deformed to allow the camera module 301 to be inserted into the socket 101 while securing the spring property of the first latch 106 which prevents the camera module 301 from being separated after insertion. ) Can be miniaturized.

In the socket 101 of the present embodiment, the recess 111 is formed in the edge 102ab of the socket housing 102. By the concave portion 111, the connecting portion 110 is further thinned, and torsion is easily generated in the connecting portion 110, thereby increasing the torsional elasticity of the connecting portion 110. For this reason, the first latch 106 can be made shorter, and the socket 101 can be further miniaturized.

Subsequently, one example of another embodiment will be described with reference to FIG. For convenience of explanation, this embodiment is called a second embodiment. In the second embodiment, the same parts as those in the first embodiment will be denoted by the same reference numerals and the description thereof will be omitted. This embodiment is an application example to the metal parts constituting the camera module socket.

5 is a perspective view of the socket 501 (camera module socket). In the present embodiment, the socket 501 includes a pair of plastic flat plates 502 and a pair of metal parts 503. The pair of plastic plates 502 face each other. In the plastic flat plate 502, neither the first latch 106 nor the second latch 107 is formed. Also, a pair of metal parts 503 face each other. The first latch 106 and the second latch 107 are formed in the metal part 503. The plastic flat plate 502 and the metal part 503 are alternately fixed side by side by a fixing member (not shown) to form a rectangular parallelepiped accommodating space 121.

Also in this embodiment, the camera module 301 is located in the opening 121a of the socket housing 102, and slides along the rolling surface of the metal part 503 toward the bottom of the socket housing 102 as it is. It is accommodated in the space 121. Also in this embodiment, the lower portion of the camera module 301 pressurizes the first latch 106 outwardly with respect to the accommodation space 121 to elastically displace the first latch 106, thereby connecting the connection portion 110. ) Is twisted in the direction S. In addition, the first latch 106 tries to return to the receiving space 121 side due to the elasticity of the first latch 106 or the torsional elasticity of the connecting portion 110, so that the first latch 106 is a cutout portion of the camera module 301. 302). That is, even in this embodiment, the fall prevention part 108 of the first latch 106 and the cutout part 302 of the camera module 301 are coupled so that the camera module 301 does not leave the socket 101. .

In addition, the latch structure formed by extending the connecting portion 110 from the first latch 106 applied to the socket 101 of the first embodiment or the socket 501 of the second embodiment is applied to not only the socket 101 but also other components. Needless to say, it can be applied.
