The projecting piece 7c of the clamp fitting 7 and the flange 6c of the bush 6 are sandwiched between the cable drawing wall 5a of the cover 5 and the spacer 8 is located inside the cover 5 in this state. Between the cable lead-out wall 5a. The spacer 8 surrounds the connector main body connecting portion of the cable 2 with the protruding piece pressing plate 8 a and each leg piece 8 b, and the cable 2 is connected between the protruding piece pressing plate 8 a of the spacer 8 and the connector main body 4. A cable storage space 9 for storing the connector main body connecting portion is formed, and the contact connection portion in the connector main body connecting portion of the cable 2 is protected. The notch portion 8c of the spacer 8 is sufficiently more than the cross-sectional shape of the cable 2 so that various cables having different cross-sectional shapes from the cable 2 can be inserted, as in the case of the interchangeable hole 5b of the cover 5. A large portion is formed and a part thereof is opened to the upper edge or the lower edge of the protruding piece pressing plate 8a, and the connector main body connecting portion of the cable 2 extends from the upper side or the lower side of the protruding piece pressing plate 8a to the inside of the notch portion 8c. It can be inserted.

  In the connector 1 according to the present embodiment configured as described above, each projecting piece of the clamp fitting 7 fixed to the cable 2 is applied to the cable 2 when an external force (tensile force) in the direction of arrow A in FIG. 7c is received by the cable drawing wall 5a of the cover 5 through the flange 6c of the bush 6, so that the pulling force does not act on the contact connection portion of the cable 2. Further, when an external force (pushing force) in the direction of arrow B in FIG. 1 is applied to the cable 2, each protruding piece 7 c of the clamp fitting 7 is received by the protruding piece pressing plate 8 a of the spacer 8. It does not act on the contact connection part of the cable 2. Accordingly, no force is applied to the contact connection portion of the cable 2 even if an external force is applied to the cable 2 in any direction, and the connection between the cable 2 and each of the contacts 3 does not become defective or cut off. .

  In addition, each protruding piece 7c of the clamp fitting 7 fixed to the cable 2 is sandwiched between the protruding piece pressing plate 8a of the spacer 8 and the cable drawing wall 5a of the cover 5 via the flange 6c of the bush 6. The cable 2 can be attached without looseness, and the cable 2 can be secured with sufficient pulling and pushing strength, so that the connector having the pulling and pushing strength of the cable 2 can be obtained. Further, since the pulling force and pushing force of the cable 2 are received by the entire surface of each protruding piece 7c of the clamp fitting 7, each protruding piece of the clamp fitting 7 is applied even when a strong pulling force and pushing force are applied to the cable 2. 7c and the projecting piece pressing plate 8a of the spacer 8 and the cable drawing wall 5a of the cover 5 which are sandwiching the flange 7c through the flange 6c of the bush 6 are deformed, or the resin projecting piece pressing plate 8a and the cable The pull-out wall 5a is not cracked, and a higher pulling and pushing strength of the cable 2 can be ensured.

  Further, since the flange 6c of the bush 6 with the sleeve separate from the cover 5 is sandwiched between the protruding piece pressing plate 8a of the spacer 8 and the cable drawing wall 5a of the cover 5, the bush 6 is also attached to the cover 5. In addition to being able to be mounted without backlash, it is possible to ensure sufficient tensile and pushing strength. Further, since the pulling force and pushing force of the bush 6 are received by the entire surface of the flange 6c of the bush 6, even when a strong pulling force and pushing force are applied to the bush 6, the flange 6c of the bush 6 and the bush 6 are directly held. The protruding piece pressing plate 8a of the spacer 8 and the cable drawing wall 5a of the cover 5 are not deformed, and the protruding piece pressing plate 8a made of resin and the cable drawing wall 5a are not cracked. A high pulling and pushing strength of the bush 6 can be secured.

  Each protrusion 7c of the clamp fitting 7 fixed to the cable 2 is superimposed on the front surface of the flange 6c of the bush 6, and together with the flange 6c of the bush 6, the protrusion pressing plate 8a of the spacer 8 and the cable drawing wall 5a of the cover 5. Therefore, it is less affected by the dimensional error of the component parts of the connector 1 and the dimensional error of the assembly, compared with the case where only the thin protruding pieces 7c of the clamp metal piece 7 are held. The thin protrusions 7c can be easily and reliably clamped, and the thin protrusions 7c of the clamp fitting 7 are formed on the front end surface of the bush 6 facing the protrusion pressing plate 8a of the spacer 8. Since it is clamped between the protruding piece pressing plate 8a of the spacer 8 and the cable lead-out wall 5a of the cover 5 in a state of being fitted and positioned in the recess 6f, the clamping is stable. It can be carried out.

  Further, by providing the bush 6 and the spacer 8 separately from the cover 5, a molding material different from the cover 5 can be selected as the molding material for the bush 6 and the spacer 8. When a tensile force is applied to the cable 2 by selecting a soft resin or a relatively hard rubber material, the cable pulling wall of the cover 5 is connected to each protrusion 7c of the clamp fitting 7 via the flange 6c of the bush 6. When receiving with 5a, the flange 6c of the bush 6 functions as a cushioning material, and the breaking strength of the cable drawing wall 5a can be increased. By selecting a resin having higher strength than the cover 5 as the molding material of the spacer 8, the cable When a pushing force is applied to 2, the protrusion of the spacer 8 that directly receives each protrusion 7 c of the clamp fitting 7. It is possible to increase the breaking strength of the pressing plate 8a, which pulling cable 2 by, indentation strength is enhanced.

Further, the spacer 8 can secure a cable storage space 9 for storing the connector main body connecting portion of the cable 2 in the connector 1 and protect the contact connection portion of the cable 2. The spacer 8 can protect the protruding piece 7 c of the clamp fitting 7. And the flange 6c of the bush 6 can be clamped between the cable drawing wall 5a of the cover 5. In addition, the protruding piece pressing plate 8a of the spacer 8 also functions as a wall that prevents the deformation of the case 5 that is of an integral type and is difficult to secure strength.

  As shown in FIGS. 3, 4 and 6 to 11, the connector 1 according to the present embodiment is formed from the left and right side portions of the through hole 5b in which the cable lead-out wall 5a of the cover 5 is opened at the center thereof. Each of the projections 5f has an elongated pin-like positioning projection 5f that projects in parallel to the front, and each projection 5f has a positioning through hole 6g formed in the flange 6c of the bush 6 and each projection piece 7c of the clamp fitting 7. Is inserted into the positioning through hole 8d formed in the protruding piece pressing plate 8a of the spacer 8, and the cover 5, bush 6, clamp fitting 7 and spacer 8 are positioned. Has been. As a result, the cable lead-out wall 5a of the cover 5, the flange 6c of the bush 6, the projections 7c of the clamp fitting 7, and the projection pressing plate 8a of the spacer 8 are overlapped without being displaced. 7c can be stably held between the protruding piece pressing plate 8a of the spacer 8 and the cable drawing wall 5a of the cover 5 together with the flange 6c of the bush 6. Even when a strong tensile force is applied to the cable 2 or the bush 6, the projection 5 f of the cover 5 penetrates the through hole 7 d of the clamp metal 7 and the through hole 6 g of the bush 6. 7 is not drawn into the bush hole 6 d of the bush 6, and the flange 6 c of the bush 6 is not drawn into the interchange hole 5 b of the cover 5. These also increase the pulling and pushing strength of the cable 2.

  As shown in FIGS. 4, 5, and 9, the connector 1 according to the present embodiment has a slit-like positioning groove 8e at the tip of each leg piece 8b of the spacer 8, and each positioning groove 8e The spacer 8 is positioned with respect to the connector body 4 by being fitted with narrow positioning protrusions 4e formed to project from the left and right side surfaces of the cover fitting portion 4b of the connector body 4. Thereby, the protruding piece pressing plate 8a of the spacer 8 can be stabilized, and each protruding piece 7c of the clamp fitting 7 together with the flange 6c of the bush 6 is connected to the protruding piece pressing plate 8a of the spacer 8 and the cable drawing wall 5a of the cover 5. Can be stably held between.

  In the connector 1 according to the present embodiment, as shown in FIGS. 1, 2, 4 to 7, and 9, the connector body 4 drops one corner of the flange 4d of the cover fitting portion 4b. The connector 1 has corner drop portions 4f that define the upper, lower, left and right sides of the connector 1, the corner portions of the cover 5 corresponding to the corner drop portions 5g, the flanges 6c of the bush 6 and the corners of the projecting piece pressing plate 8a of the spacer 8. The corners 5g, 6h, and 8f are formed in the respective parts, and the connector 1 is assembled only when the upper, lower, left, and right sides of the connector body 4 are aligned with the upper, lower, left, and right sides of the cover 5, bush 6, clamp fitting 7, and spacer 8. It is possible.

In the connector 1 according to the present embodiment, a clamp fitting 7 is fixed to a connector main body connecting portion of a cable 2 whose one end is connected to a connector main body 4 via a contact 3, and the cable 2 is bushed from the other end where the plug pin is not attached. 6 is inserted into the bushing hole 6d of the cover 6 and then the fitting hole 5b of the cover 5, and then the notch 8c of the spacer 8 is fitted into the cable 2 between the connector body 5 and the clamp fitting 7 from the peripheral side. The spacer 8, the clamp fitting 7, the bush 6, and the cover 5 are attached in this order from the connector body 2 side to the cable 2 that is pulled out to the rear of the cable, and in this state, the cover 5 is moved to the connector body 4 side while By fitting the open end to the outside of the cover fitting portion 4b of the connector body 4 from the rear side, it can be assembled in the state shown in FIGS. Since means for inserting the connector body connection part of the cable 2 to the protrusion pressing plate 8a of the spacer 8 is a cut-away portion 8c instead of holes, a and clamp bracket 7 before connecting the cable 2 to the connector body 4 cable 2 It is not necessary to attach the spacer 8 to the cable 2 in advance before being fixed to the cable 2, the connector body 4 and the cable 2 can be easily connected and the clamp fitting 7 can be easily fixed, and the connector 1 can be easily assembled.

  The connector main body 4 of the connector 1 according to the present embodiment can be connected regardless of the cross-sectional shape of the cable as long as it is a cable in which the number of contacts 3 that can be attached to the connector is fixed to one end. 5 can be pulled out to the rear of the cover 5, so that the connector main body 1, the cover 5, and the spacer 8 are connected to one end of each cable. Can be attached to various cables without backlash, and a connector having cable pulling and pushing strength can be configured. Also, for example, even with connectors having different standards such as D terminals, component terminals, and HDMI terminals, the cover 5 and the spacer 8 can be shared at one end of various cables by forming the cover fitting portion 4a in the connector body. A connector having the same function and effect as the connector 1 described above, that is, can be attached to various cables without backlash, and a connector having tensile strength and pushing strength of the cable can be configured. Therefore, by sharing the components of the connector 1 such as the connector main body 1, the cover 5, and the spacer 8, the cost of the connector can be easily reduced.

  In addition, since the cover 5 is integrated into the upper and lower parts without using the upper and lower split structure, the cover has a split upper and lower structure. For example, a hook of one split cover is attached to the other split cover. In the structure that is held by the holes, the holes for the hooks and the split lines are formed, the appearance is deteriorated, and the number of assembly steps increases as the number of parts increases, but this is not the case. Further, when the cover 5 is shared, it is difficult to obtain cable pulling and pushing strength, but this can be sufficiently ensured.
