Detailed Description

The technical solution protected by the present invention will be specifically described below with reference to the accompanying drawings.

The utility model provides a connector joint fixed knot constructs for be fixed in on a mounting panel A. Referring to fig. 1 to 5, the connector terminal fixing structure mainly includes a connector terminal 10, a fixing housing 20 and a limiting collar 30.

First, the mounting plate a is provided with a plurality of through holes a1 corresponding to the outer shape of the connector header 10 for mounting, and the mounting plate a has an outer side a2 and an inner side A3, as shown in fig. 1. However, the mounting plate a disclosed in the present drawings is only for the convenience of those skilled in the art to clearly understand and implement, and therefore the shape of the mounting plate a and the shape of the through hole a1 should not be taken as a limitation of the present invention.

In the present embodiment, the connector terminal 10 is a female terminal for inserting a mating connector B, but the present invention is not limited thereto. In addition, the present invention is not limited to the type or kind of connector, and the connectors disclosed in the drawings are only for the convenience of the reader, and should not be directly used as the limitation of the present invention. In the present embodiment, the connector contact 10 has a first outer edge 11 and a second outer edge, and the outer diameter of the first outer edge 11 is larger than that of the second outer edge. The connector contact 10 has a plurality of resilient arms 111 at the first outer edge 11 and a connecting wall 13 formed between the first outer edge 11 and the second outer edge, but the present invention is not limited thereto, and the design requirements can be adjusted.

The fixed housing 20 is integrally formed by plastic injection molding and is fitted over the connector terminal 10. Specifically, the fixed housing 20 is provided with a plurality of fastening holes 201 corresponding to the elastic arms 111. The elastic arms 111 are respectively buckled to the corresponding buckling holes 201, so that the connector 10 and the fixed housing 20 are longitudinally locked and cannot be easily separated. The fixed housing 20 mainly includes a cylinder 21 and a stopper 22 formed at one end of the cylinder 21, wherein the cylinder 21 is inserted through one of the through holes A1 of the mounting plate A so that the stopper 22 is attached to and abutted against the outer side surface A2 of the mounting plate A. The stop portion 22 is substantially annular and surrounds the outer edge of one end of the barrel 21, and the fastening holes 201 are formed at one end of the barrel 21 away from the stop portion 22. A plurality of hooks 23 are disposed on one side of the barrel 21, and each hook 23 is spaced apart from the stopper 22. In the present embodiment, each hook 23 is in a strip shape, and each hook 23 is disposed on the opposite two sides of the cylinder 21, but the present disclosure is not limited thereto.

The position-limiting ring 30 is integrally formed by injection molding of plastic. The position-limiting ring 30 is movably fitted around the outer edge of the barrel 21 and is provided with at least one elastic hook 31. The elastic hook 31 is a reverse hook and can be selectively locked corresponding to one of the hooks 23, so that different clamping intervals t are formed between the stopping portion 22 and the limiting collar 30 to jointly clamp the mounting plate a. In the present embodiment, the elastic hooks 31 are elongated corresponding to the hooks 23, and the number of the elastic hooks 31 is two and are respectively disposed on two sides of the position-limiting ring 30 corresponding to the hooks 23, but the present invention is not limited thereto. Therefore, the elongated hooks 23 and the elastic hooks 31 can have a larger fastening area to obtain a good fastening effect, and the hooks 23 and the elastic hooks 31 are disposed on two opposite sides to enable the fixed housing 20 and the position-limiting ring 30 to be evenly stressed and not to be easily loosened.

To explain, each hook 23 is provided with a first guiding surface 231, which is substantially a right-angle trapezoid. Specifically, the right angle of each hook 23 faces the stopping portion 22 to allow the elastic hook 31 to be locked without slipping off, and each first guiding surface 231 facilitates the elastic hook 31 to move toward the hook 23 close to the stopping portion 22. In addition, the left and right sides of the elastic hook 31 are also provided with a second guiding surface 311 corresponding to each hook 23 and a fastening surface 312 located at the other side of the second guiding surface 311, so as to form a right-angled trapezoid approximately opposite to each hook 23. Specifically, the second guiding surface 311 of the elastic hook 31 faces the stopping portion 22 to facilitate the elastic hook 31 to move toward the hook 23 close to the stopping portion 22, and the right-angled fastening surface 312 is used for fastening the elastic hook 31 with the corresponding hook 23 after positioning without slipping.

Preferably, the fixing structure of the connector 10 of the present invention further includes an outer rubber ring 40 and an inner rubber ring 50. A groove 221 for accommodating the outer rubber ring 40 is concavely arranged on one side of the stopping portion 22 adjacent to each hook 23, so that the outer rubber ring 40 can be clamped between the outer side surface a2 of the mounting plate a and the groove 221 to achieve sealing, thereby preventing water vapor from penetrating into a gap between the through hole a1 and the fixed housing 20. A retaining wall 24 is protruded from the inner edge of the fixed housing 20, and the inner rubber ring 50 is sleeved on the second outer edge of the connector 10, so that the inner rubber ring 50 is clamped between the connecting wall 13 and the retaining wall 24, thereby preventing water vapor from penetrating into the gap between the connector 10 and the fixed housing 20.

Please refer to fig. 2 and fig. 3, which are schematic installation diagrams of the present creation. The cylinder 21 of the fixed housing 20 is first inserted into the through hole a1 from the outer side a2 of the mounting plate a until the stopper 22 abuts against the outer side a2 of the mounting plate a. Then, the position limiting ring 30 is sleeved on the cylinder 21 and slides towards the mounting plate a until the front end of the elastic hook 31 abuts against the inner side surface a3 of the mounting plate a and the elastic hook 31 is clamped on the clamping hook 23. Finally, the connector 10 is inserted into the barrel 21 of the fixed housing 20, so that the elastic arms 111 on the first outer edge 11 are buckled in the buckling holes 201 of the barrel 21 to fix the connector 10. Thus, the assembly of the present invention is completed, so that the connector 10 can be fixed on the inner side of the mounting plate a, and the butt connector B and the connector 10 can be conveniently and directly plugged by an operator, as shown in fig. 4 and 5.

Please refer to fig. 6, which is a schematic view of the present invention installed on another thicker mounting plate a'. Unlike the elastic hook 31 shown in fig. 3, which is fastened to the first hook 23, the mounting plate a 'has a relatively thick thickness, so that when the front end of the elastic hook 31 abuts against the mounting plate a', the elastic hook 31 is fastened to the second hook 23 to form a relatively wide clamping gap t. Therefore, the hooks 23 on the barrel 21 of the fixed housing 20 can be engaged with the elastic hooks 31 of the position-limiting collar 30 according to the mounting plates a with different thicknesses, so as to achieve good versatility, and further effectively reduce the production cost and the inventory pressure.

The utility model also provides a fixed knot constructs, its and the connector joint fixed knot constructs as before mainly the difference lies in not including this connector joint 10 and this interior rubber ring 50. Therefore, the fixing housing 20 of the fixing structure of the present invention can be matched with any type and kind of connector connectors as long as it can be installed on the cylinder 21 of the fixing housing 20, and the installation manner can be buckling, plugging, locking or embedding, etc., which is not limited by the present invention.

The above only is the embodiment of the present invention, not limiting the patent scope of the present invention, all the equivalent structures or equivalent processes that are used in the specification and the attached drawings or directly or indirectly applied to other related technical fields are included in the patent protection scope of the present invention.
