The invention is described in further detail below with reference to the figures and the examples, but without limiting the invention.
The illustrated bundling connector comprises a male connector 1, a female connector 2 and a threaded sleeve 3 for connecting the male connector 1 and the female connector 2, wherein the tail end of the male connector 1 is connected with a signal wire harness, and the threaded sleeve 3 is sleeved on the male connector 1 and fixedly connected with the male connector and the female connector through threads on the female connector 2. Of course, those skilled in the art will recognize that a threaded insert is preferred.
Fig. 1 is a schematic perspective view of a male connector of the cluster connector of the present invention, showing a threaded sleeve fitted over the male connector. Fig. 2 is a schematic longitudinal sectional view of a portion of the male connector shown in fig. 1. As shown in fig. 1 and 2, the male connector 1 includes a first outer conductor 11 having a plurality of coaxial passages, a first inner conductor 12 and a first insulating medium 13 disposed in each of the coaxial passages, the first insulating medium 13 surrounding and fixing the first inner conductor 12, and an elastic contact member 14 disposed between the first insulating medium 13 and the first outer conductor 11 and protruding from an end surface of the first outer conductor 11 toward the female connector side. The front end of the first inner conductor 12 is a deep hole structure, and a groove is formed in the hole wall. The first insulating medium 13 and the first inner conductor 12 may be an interference fit.
As best shown in fig. 2, an annular flange 17 is provided on the end face of the first outer conductor 11 toward the female terminal side. The annular flange 17 may preferably be along the peripheral direction of the elastic contact element 14. Therefore, when the male joint and the female joint are butted, the plurality of annular contacts replace surface-to-surface contacts, poor contact caused by the surface-to-surface contacts is greatly reduced, and the contact effect is improved. The annular flange 17 may be made integral with the first outer conductor 11 or separate therefrom. The provision of an annular flange is preferred or not possible.
The first outer conductor 11 is provided with a guide hole 16 in the axial direction toward the female terminal-side end, and the guide hole 16 is schematically shown in an intermediate position in fig. 1. The outer surface of this end of the first outer conductor 11 is also provided with one or more tabs 15 (three are shown, only two are visible). The guide hole 16 and the convex key 15 can play a role in positioning and guiding in the butt joint process of the male joint and the female joint.
Fig. 3 is a perspective view of the elastic contact member of the male tab of the cluster connector of the present invention. As shown in fig. 3, the elastic contact member may preferably be provided in a ring-shaped structure having a groove on a wall surface.
Fig. 4 is a perspective view of a female terminal of the bundle connector of the present invention, and fig. 5 is a partial longitudinal sectional view of the female terminal shown in fig. 4. As shown in fig. 4 and 5, the female connector 2 also includes a second outer conductor 21 having a plurality of coaxial passages corresponding to the number of coaxial passages of the first outer conductor 11, respectively, a second inner conductor 22 and a second insulating medium 23 provided in each of the coaxial passages, the second insulating medium 23 surrounding and fixing the second inner conductor 22. The second inner conductor 22 is a cylindrical structure, and when the male and female connectors are butted, the second inner conductor 22 is inserted into the deep hole structure of the first inner conductor 12. The second insulating medium 23 and the second inner conductor 22 may be an interference fit. A groove 26 is formed in each coaxial channel of the second outer conductor 21, and the elastic contact element 14 of the male connector 1 can be inserted into the groove 26. After the male and female connectors are butted, the elastic contact element 14 is tightly attached to the wall surface of the groove 26. Thus, the toroidal contact is formed, and even if the connector is subjected to vibration in various directions, poor contact does not occur. When the elastic contact element 14 is configured as a ring structure with a split groove on the wall surface, the split groove can be configured to enhance the matching effect of the elastic contact element 14 and the groove 26.
The second outer conductor 21 is provided with a guide post 24 in the axial direction at the end toward the male connector side, and the guide post 24 is schematically shown in an intermediate position in fig. 4. The guide posts 24 may be formed integrally with the second outer conductor 21, or the guide posts 24 may be mounted in slots formed in the second outer conductor 21 by interference fit. When the male connector 1 is butted with the female connector 2, the guide posts 24 are inserted into the guide holes 16 in the male connector 1. Preferably, the free end of the guide post 24 is a hole-like structure with a wall surface provided with a split groove, which facilitates better insertion of the guide post 24 into the guide hole 16.
Key grooves 25 (three are shown) are also formed in the inner wall of the second outer conductor 21 of the female terminal 2. During installation, the convex key 15 on the male connector 1 is aligned to the corresponding key groove 25 for positioning, then the guide column 24 is pre-inserted into the guide hole 16, due to the groove splitting structure of the guide column 24, the sound of the guide column impacting the lower end of the guide hole can be heard forcefully under the positioning and pre-guiding effects, then the male connector and the female connector are screwed up through the screw sleeve 3, and connection is completed quickly and conveniently.
Of course, it will be readily appreciated by those skilled in the art that the reverse configuration may be adopted, i.e. the second outer conductor 21 is provided with a guide hole and the first outer conductor 11 is provided with a corresponding guide post. The guide holes may be provided at other positions of the respective end portions, although an intermediate position is preferred. The number of guide holes and guide posts is not limited to one. The use of a key and a keyway is also preferred.
Fig. 6 schematically shows a butt-assembled view of the male and female terminals of the cluster connector of the present invention, the male terminal being exemplified by the one shown in fig. 1. With reference to this figure, the construction of the present invention will be more readily understood by those skilled in the art. The figure shows that the end face of the second insulating medium 23 of the female connector 2 facing the male connector side ends at the bottom of the recess 26 and the end face of the first insulating medium 13 and the first inner conductor 12 of the male connector 1 facing the female connector side ends at the end face of the resilient contact element 14 facing the female connector side. This configuration is preferred to facilitate machining and docking. However, it will be appreciated by those skilled in the art that the end surface of the first inner conductor 12 towards the female connector side may be flush with the same side end surface of the corresponding coaxial channel (not shown); in addition to the elastic contact elements 14 and the recesses 16, the other elements may be of conventional construction, i.e. the end surface of the second insulating medium 23 of the female connector 2 facing the male connector side is flush with the same side end surface of the corresponding coaxial channel, and the end surfaces of the first insulating medium 13 and the first inner conductor 12 of the male connector 1 facing the female connector side are flush with the same side end surface of the corresponding coaxial channel (not shown).
Fig. 6 also illustrates the seal ring 4, and in order to achieve a sealing effect, it is preferable that the inside of the wall surface of the second outer conductor 21 of the female connector 2 is provided with the seal ring 4 in the circumferential direction, and fig. 5 schematically illustrates a seal ring groove 27 in which the seal ring 4 is installed. In addition, when the key groove 25 is provided, the bottom of the key groove 25 on the female joint 2 is higher than the top of the seal ring 4, that is, as schematically shown in fig. 7, the bottom of the key groove 25 is higher than the top of the seal ring 4 by a distance H. Therefore, when the male joint and the female joint are assembled, the wall surface of the female joint 2 can completely abut against the sealing ring 4, and full sealing is realized.
Of course, the above is a preferred embodiment of the present invention. It should be noted that, for a person skilled in the art, several modifications and refinements can be made without departing from the basic principle of the invention, and these modifications and refinements are also considered to be within the protective scope of the invention.
