[Industrial applications]

 The present invention relates to a receptacle connector used between narrow spaces of communication equipment.

[0002]

[Prior art]

 The conventional receptacle connector 3 is composed of a center contact 6, an insulator 9, and an outer conductor 2. The center contact 6 is made by cutting and pressing, and is fixed to the insulator 9 by press fitting or integral molding. The insulator 9 is inserted into the outer conductor 2 and is punched at a plurality of positions from above the outer conductor 2 to fix the insulator 9. When the outer conductor 2 is provided with a plurality of slits 4 from the side of the L-shaped plug fitting port 5 and the outer conductor 2 is provided with spring property by fitting the slits 4, the L-shaped plug connector 1 is mated. It has a contact force of. The length of the slit 4 is required to be more than half of the outer conductor 2 to maintain the contact force, and even if the slit 4 is long, the outer conductor 2 must be able to fix the insulator 9 with one component.

The receptacle connector 3 is soldered to a board. After that, when the L-shaped plug connector 1 is engaged, the cable clamp portion 12 of the L-shaped plug connector 1 is placed on the end side of the L-shaped plug mating port 5 of the outer conductor 2 as shown in FIG. The mating height (= L1) when the L-type plug connector 1 is fitted to the conventional receptacle connector 3 is about 4 to 5 mm, and the diameter (= L2) of the cable clamp portion 12 at that time is 1 to It is about 1.5 mm.

[0004]

[Problems to be solved by the device]

 Recently, even lower profile is required. As such a medium design concept, it is desired to obtain a stable contact force even if it is inserted and removed 10 times or more, but since the height of the conventional receptacle connector 3 is not sufficient for the length of the slit 4, Stable contact force is lost after ~ 5 insertions and removals. With the shape of the conventional receptacle connector 3, when mated with the L-shaped plug connector 1, the mating height as a connector is increased by at least the outer diameter of the cable clamp portion 12. If the height of the receptacle connector 3 is further reduced in order to reduce the mating height, the length of the slit 4 becomes shorter, so that a stable contact force can be obtained only with less than 4 to 5 times of insertion and removal. I will end up.

Under these circumstances, the present invention aims to provide a receptacle connector 3 which has a low mating height and which can obtain a stable contact force even when it is inserted and removed at least about 10 times. At present, when the height of the receptacle connector 3 is 4 mm or less, it is difficult to insert and pull out 10 times or more to obtain a stable contact force.

[0006]

[Means for Solving the Problems]

 The present invention has been made in consideration of the above problems, and is mainly composed of a central contact 6, an insulator 9, and an outer conductor 2. The insulator 9 fixes the center contact 6, and the outer conductor 2 fixes the insulator 9. The outer conductor 2 has a mating hole 7 with the L-shaped plug connector 1 at one end side, and a plurality of slits 4 are provided from the edge of the mating hole 7 and a contact 10 to the board 10 at the other end side. have. In the receptacle connector 3 including the center contact 6, the insulator 9, and the outer conductor 2, one or more cutout portions 8 for escaping the cable clamp portion 12 of the L-shaped plug connector 1 are provided on one end side of the outer conductor 2. The plug connector is provided so as to communicate with the fitting hole 7.

The size of the cutout portion 8 is such that the surface A 13 of the L-shaped plug connector 1 is flush with the end side of the L-shaped plug mating opening 5 of the outer conductor 2, and the cable clamp portion 12 of the L-shaped plug connector 1 is formed. It suffices if it can be inserted so as not to contact the outer conductor 2, and the shape may be U-shaped, U-shaped or any shape. Moreover, you may provide the cutting part 8 in 2-3 places.

[0008]

[Action]

 By providing the cutout portion 8, the cable clamp portion 12 of the L-shaped plug connector 1 does not contact the outer conductor 2, and the surface A13 of the L-shaped plug connector 1 is the edge of the L-shaped plug mating port 5 of the outer conductor 2. And can be easily made the same. Therefore, the length of the slit 4 can be easily increased without changing the engaging height. Further, by providing the cutout portion 8, the contact height can be reduced by ignoring the contact force, and by ignoring the contact height, the conventional mating height or 10 times or more inserting / removing is sufficient. It is easy to obtain a good contact force.

【Example】

 An embodiment using the present invention will be described based on the drawings. FIG. 1 is a perspective view of an L-shaped plug connector 1 and a receptacle connector 3 of the present invention. FIG. 2 is a perspective view of the L-shaped plug connector 1 fitted to the receptacle connector 3 of the present invention. As in the conventional case, the center contact 6 may be a cut product or a pressed product, and is fixed by an insulator 9. The fixing method may be press fitting or integral molding. The insulator 9 is manufactured by press working, is provided with the slit 4 and the cut portion 8 and is inserted into the cylindrical outer conductor 2, and is fixed to the outer conductor 2 by punching the outer conductor 2 at a plurality of positions. .

By providing the slit 4, the outer conductor 2 has a spring property. The length of the slit 4 affects the number of times of insertion and removal and the contact force. That is, if the length of the slit 4 is short, the contact force decreases with a small number of times of insertion and removal, but if the length is long, the number of times of insertion and removal can be increased. The size of the cutout portion 8 is such that the surface A13 of the L-shaped plug connector 1 is the same as the end side of the L-shaped plug mating port 5 of the outer conductor 2 as shown in FIG. It suffices if it can be inserted so that the cable clamp portion 12 does not come into contact with the outer conductor 2.

If the above-mentioned state is brought about at the time of mating, the shape of the cut portion 8 may be U-shaped (shown in FIG. 1), U-shaped or trapezoidal. Ideally, a U-shape that is in the above-mentioned state at the time of mating and matches the shape of the cable clamp portion 12 is preferable. The receptacle connector 3 of the present invention is also soldered to the board as in the conventional case. Since the cutout portion 8 is provided, the pull-out direction of the cable 11 is determined to be the direction in which the cutout portion 8 is present. In other words, the pull-out direction of the cable 11 is determined by the positional relationship between the contact 10 of the outer conductor 2 and the cutout portion 8 and the position of the contact insertion hole on the substrate.

However, it is easy to deal with this by deciding the pull-out direction of the cable 11 at the time of processing the mounting hole of the board, and it is even easier if the cutouts 8 are provided at several places instead of one place. The L-type plug connector 1 is the same as the conventional one except that when the L-type plug fitting hole 7 is fitted into the L-shaped plug fitting hole 7, the surface A13 is at the same height as the opening end of the outer conductor 2.

[0013]

[Effect of device]

 By providing the outer conductor 2 with the notch 8 for escaping the cable clamp portion 12 of the L-shaped plug connector 1 on the L-shaped plug engaging hole side, the following two effects are obtained. Assuming that the contact force may be reduced by inserting and removing 4 to 5 times as in the conventional case, in the example shown in FIG. 3, the outer diameter (= L2) of the cable clamp portion 12 is 1 to 1. The mating height of 5 mm can be reduced. That is, it can be reduced by 20 to 25% as compared with the conventional mating height. If the mating height can be the same as the conventional one (for example, 4 to 5 mm in the example of Fig. 3), the slit 4 can have a sufficient length, so that the contact force has been reduced by the conventional 4 to 5 times of insertion and removal. Can be improved more than 10 times with the same material.
