Description: BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a connector housing structure, and more particularly to a structure for releasing a lock of a connector to a housing. 2. Description of the Related Art FIG. 6 shows a conventional connector housing structure.
This will be described with reference to FIG. [0003] FIG. 6 (a) ~ (d) show various states in which the cable connector 61 is mounted on the metal frame 51. FIG. 1A shows a state in which frames 51 are stacked in three stages, and cable connectors 61 are attached to the middle and lower stages on the left and each stage on the right. However, the lower cable connector 61 on the right side is in a reverse insertion state (being inserted upside down). [0005] The left side of (b) shows a state where the cable connector 61 is reversely inserted, and the right side of (b) shows a state where the cable connector 61 is normally attached to the frame 51. A substantially U-shaped locking leaf spring 5 is provided at the center of the frame 51.
2, on both sides of the frame 51, substantially L-shaped locking leaf springs 52 are formed integrally with the frame 51, respectively. The frame 51 includes a pair of reverse insertion preventing portions 5.
3 are formed integrally with the frame 51 at the mounting portions of the cable connectors 61 on the left and right sides, respectively. The cable connector 61 has a structure in which a cable 63 is fixed to a main body 62, a key 62A is formed near the front of the left and right sides of the main body 62, and a notch 62B is formed on the rear side of the key 62A. I have. [0007] In the state shown on the left side of (b), the pair of keys 62A of the cable connector 61 is in contact with the pair of reverse insertion preventing portions 53 of the frame 51. Cannot be moved. In the state shown on the right side of (b), the cable connector 61 is normally mounted on the frame 51, and the pair of keys 62A are locked at the tips of the pair of locking leaf springs 52 (at this point). See (d) for details). Therefore, the cable connector 61 cannot be moved relative to the frame 51 in the direction opposite to the mounting direction. At this time, as shown in (c),
The pair of cutouts 62B of the cable connector 61 face the pair of reverse insertion prevention portions 53. To release the cable connector 61 from the engagement of the pair of locking leaf springs 52 in the state shown on the right side of (b), the lock release jig 81 is moved from the solid line position to the main body 62 of the cable connector 61. It is inserted between the side surface and the tip of each locking leaf spring 52 to the position indicated by the two-dot chain line. Then, each locking leaf spring 52 is elastically deformed from the thick line position to the thin line position. Therefore, the cable connector 61 can be moved relative to the frame 51 in the direction opposite to the mounting direction. FIG. 7 shows an overall view of a housing structure of a conventional connector. A plurality of frames 51 each having two cable connectors 61 mounted on a housing 71 are mounted one on top of another. A pair of sliders 72 are slidably mounted on the left and right sides of the housing 71 in the vertical direction, and the cam grooves 72A formed on each slider 72 are engaged with the projections 73 formed on each frame 51. By sliding the pair of sliders 72 downward,
Each frame 51 sequentially moves in the connector fitting direction, and each cable connector 61 fits into a mating connector (not shown). When the pair of sliders 72 is slid upward, the respective frames 51 are sequentially moved in the connector removing direction, and the respective cable connectors 61 are separated from the mating connector. [0011] Since the conventional housing structure of the connector is a front release structure (the lock is released from the mating surface side of the cable connector), a space on the mating surface side of the connector is provided. The front release structure is inconvenient, for example, when the width of the front release structure is narrow, or when the housing for locking the connector is fixed to the printed circuit board and cannot be easily separated. In view of the above, the present invention solves the above-mentioned drawbacks of the conventional housing structure of the connector, and deals with the case where the space on the mating surface side of the connector is narrow. ) To provide a structure. [0013] The present invention employs the following means to solve the above-mentioned problems. In a housing fixed to a board on which a connector is mounted, the housing includes a housing for housing the connector, a mating connector insertion portion into which a mating connector is inserted, and the connector and the mating connector. A locking portion provided with a locking portion for locking the mating connector at a locking position when the mating connector is fitted, and a jig insertion portion of a jig for unlocking the mating connector. and, wherein the mating connector insertion portion and the jig insertion portion are juxtaposed, and, the locking portion is formed so as to face to both the jig insertion portion and the mating connector insertion portion, wherein Mating connector insertion

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A housing structure of a cable connector according to an embodiment of the present invention will be described with reference to FIGS. FIG. 1 shows a state before the cable connector 11 is accommodated in the resin housing 1. The cable connector 11 is configured by fixing a cable 13 to a main body 12.
A is formed, and a notch 12B is formed on the rear side of the key 12A.
Is formed. FIG. 2 shows a detailed structure of the housing 1. The housing 1 is fixed to a printed circuit board. A total of six cable connectors 11 can be inserted into the housing 1, three in each of two rows. The insertion structure of the six cable connectors 11 is the same. Each of the six insertion portions 2 is formed in a substantially U-shape, and a locking leaf spring (lock portion) 2A for locking the connector is formed from the upper portion to the middle portion of the inner surfaces of the left and right side walls of the housing 1. The tip of the locking leaf spring 2A becomes the locking portion 2B. An inner wall 2C is formed to face each locking leaf spring 2A, and the width of the inner wall 2C is
About half the width of A connector guide surface 2D is formed parallel to and adjacent to the locking leaf spring 2A, and a reverse insertion prevention portion 2E for preventing reverse insertion of the connector is formed below the connector guide surface 2D. The upper surface is the reverse insertion prevention surface 2F. A connector guide surface 2G is also formed on the rear surface of the inner wall 2C, and connector guide surfaces 2H, 2I, and 2J are also formed on the front surface of the wall facing the connector guide surface 2G. The connector guide surface 2I is formed on an inclined surface for facilitating insertion of the connector into the insertion section 2. A jig insertion portion 3 of a lock release jig to be described later is formed adjacent to the insertion portion 2. FIGS. 3A to 3C are three views showing a state in which two cable connectors 11 are accommodated in the housing 1. FIG. In FIG. 3A, bosses 2K formed at several places of the housing 1 fit into holes provided at several places of the printed circuit board 41, and the housing 1 is positioned. Accommodates a socket connector 21 fixed to a printed circuit board 41. Right cable connector 11
Is properly inserted into the insertion portion 2 and the socket connector 2
1 is fitted. At this time, a pair of notches 12B
Corresponds to the pair of reverse insertion prevention units 2E. In this state, the pair of keys 12A of the cable connector 11 are locked by the locking portions 2B of the pair of locking leaf springs 2A.
Can not leave. The left cable connector 11 is inserted upside down into the insertion section 2 (FIG. 3).
(B), (c), see FIG. 4).
The one pair of keys 12A abuts on the reverse insertion prevention surfaces 2F of the pair of reverse insertion prevention portions 2E. Therefore, the cable connector 11 cannot reach the position where it fits into the socket connector 21. This state will be described with reference to FIG. 4. On the left side of FIG. 4, a pair of keys 12A of the cable connector 11 is in contact with a pair of reverse insertion prevention surfaces 2F of the insertion portion 2. Therefore, it is possible to prevent the cable connector 11 from being turned upside down and fitted into the socket connector 21. Next, a method for releasing the cable connector 11 from the engagement of the pair of locking leaf springs 2A will be described with reference to FIG. The left side of FIG. 5 is a diagram in which the lock release jig 31 is inserted into the jig insertion portion 3 in a state where the cable connector 11 is not inserted into the insertion portion 2 for reference of understanding of the present invention. The left and right sides of the lock release jig 31 elastically deform the pair of locking leaf springs 2A outward. The right side of FIG. 5 shows a state where the cable connector 11 is fitted to the socket connector 21.
FIG. 4 is a diagram in which a lock release jig 31 is inserted into a jig insertion section 3. Since each of the pair of locking leaf springs 2A is elastically deformed outward, each locking portion 2B is separated from each key 12A of the cable connector 11. Therefore, in this state, the cable connector 11 can be detached from the socket connector 21. As is apparent from the above description, according to the present invention, the following effects can be obtained. 1. The rear release structure can be obtained in response to the case where the space on the mating surface side of the connector is narrow or there is no space. 2. Even connectors designed for front release can be adopted for rear release. 3. Since the connector guide surface formed in the insertion portion of the connector in the housing has an inclined surface, it is easy to insert the connector into the insertion portion.
