Detailed Description

The present invention will be described in further detail with reference to the following drawings and specific examples, which should not be construed as limiting the invention.

The utility model discloses connector tied in a bundle includes male joint 1, female joint 2 and connects male joint 1 and female joint 2's swivel nut 3, 1 tail-end connection signal pencil of male joint, and 3 covers of swivel nut are established on male joint 1 to through screw thread fixed connection male, female joint on the female joint 2.

Fig. 1 is a schematic structural view of a male connector of the cluster connector of the present invention. As shown in fig. 1, the male connector 1 includes a base outer conductor 11 having a plurality of coaxial channels, a first inner conductor 12 disposed in each of the coaxial channels, and a first insulating medium 13, the first insulating medium 13 surrounding the fixed first inner conductor 12. 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. The male connector 1 further comprises a first outer conductor 16 arranged around the periphery of the first insulating medium 13 and a resilient contact 14 arranged between the first outer conductor 16 and the base outer conductor 11. In the case of providing the elastic contact 14, the contact effect of the male and female terminals can be significantly improved.

The end of the base outer conductor 11 toward the female terminal side is provided with a guide hole 18 in the axial direction, and the guide hole 18 is schematically shown in an intermediate position in fig. 1. The outer surface of the end of the base outer conductor 11 is also provided with one or more raised keys 15. The guide hole 18 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. 2 is a schematic structural view of a female terminal of the cluster connector of the present invention, and fig. 3 is a view from direction B of fig. 2. As shown in fig. 2 and 3, the female connector 2 also includes a second outer conductor 21 having a plurality of coaxial passages corresponding to the same number of coaxial passages of the base 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 has a columnar structure, and when the male connector 1 is butted against the female connector 2, 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.

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 at an intermediate position in the drawing. 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 18 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 18.

Key grooves 25 (three are shown) are also formed in the inner wall of the second outer conductor 21 of the female terminal 2. When the connector is installed, the convex key 15 on the male connector 1 is aligned to the corresponding key groove for positioning, then the guide column 24 is pre-inserted into the guide hole 18, 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 forcibly under the positioning and pre-guiding effects, then the male connector and the female connector are screwed down through the threaded sleeve 3, and the 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 guide holes and the base outer conductor 11 is provided with corresponding guide posts. 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 pilot holes and posts is preferred and the use of keys and keyways is preferred for better location and guidance.

Fig. 4 is a schematic view of the configuration of the spring contact, the first outer conductor, and the base outer conductor of the male connector of fig. 1. As shown in fig. 4, the elastic contact 14 protrudes outward at an end portion (i.e., an upper end portion shown in fig. 4, the female contact 2 to be connected is not shown in this figure for the sake of simplicity) in contact with the female contact 2, forming an outer convex ramp 141 capable of contacting an end portion of the base outer conductor 11 and moving relative to the base outer conductor 11.

The elastic contact 14 is further formed with an anti-falling outer protrusion 142 in the same direction as the outer protrusion 141, and accordingly, an inner concave groove 111 is formed on the inner wall of the base outer conductor 11, and the inner groove 111 can accommodate the anti-falling outer protrusion 142 and form a certain axial movement space.

Thus, when the male and female connectors are mated, the end surface of the female connector 2 will press the elastic contact 14, so that the elastic contact 14 will be forced in the direction indicated by the arrow F in fig. 4, and thus the elastic contact 14 will move downward relatively, and due to the outer ramp 141, the elastic contact 14 will also move radially inward in the direction indicated by the arrow T relative to the base outer conductor 11 along with the downward movement. In this way, compared with the elastic contact without an outer ramp, a larger contact area can be achieved when the male and female connectors are butted, and good contact performance is obtained, and meanwhile, the elastic contact 14 can be moved to be tightly attached to the first outer conductor 16, so that the first insulating medium 13 is clamped and protected. When the contact failure of the butt surfaces of the male joint and the female joint occurs gaps due to vibration and the like, the elastic contact head 14 can rebound to perform actions opposite to the above process, so that the gaps are made up, the male joint and the female joint can be ensured to be always kept in contact, and the electromagnetic shielding failure caused by the contact failure of the male joint and the female joint is avoided. Due to the arrangement of the outer convex inclined platform, the resilience is more reliable.

Further, a spring (not shown) may be connected to a lower end portion of the elastic contact head 14, so that when a gap occurs due to a contact failure between abutting surfaces of the male and female connectors caused by vibration or the like, the elastic contact head 14 is rapidly rebounded by a restoring elastic force of the spring to maintain contact with the female connector 2.

In addition, although one anti-slip outer boss 142 is shown in fig. 4, it is easily contemplated by those skilled in the art that the number thereof may not be limited to one; its position may be in the middle of the spring contact 14 or elsewhere; it may take any suitable shape so long as the effect of preventing the elastic contact 14 from coming off is achieved.

Fig. 5 is a preferred modification of the structure shown in fig. 4, and differs from fig. 4 in that an annular flange 19 is provided on an end surface (i.e., an upper surface shown in the drawing) of the base outer conductor 11 toward the female terminal side, and the annular flange 19 may preferably be along the outer circumferential direction of the elastic contact 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.

Further, in order to achieve the sealing effect, it is preferable that, as shown in fig. 2, a seal ring 4 is provided in the circumferential direction inside the wall surface of the second outer conductor 21 of the female connector 2. 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. 6, 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 connector and the female connector are assembled, the wall surface of the female connector 2 can completely abut against the sealing ring 4, and sufficient sealing is realized. In addition, preferably, as shown in fig. 1, the male connector 1 forms a first step portion 17 at an end portion close to the signal wire harness, and correspondingly, the end portion of the screw sleeve 3 forms a second step portion 37, the first step portion 17 and the second step portion 37 are completely engaged, and two step surfaces can abut against each other, and in the process of sleeving and locking the female connector 2 by the screw sleeve 3, the second step portion 37 of the screw sleeve 3 can be completely and hermetically engaged with the first step portion 17 of the male connector 1, so that safety and reliability are achieved, and complicated installation structures such as a snap ring are avoided. This arrangement is advantageous for both connection and sealing.

Fig. 7 schematically shows a butt assembly view of the male and female connectors of the cluster connector of the present invention. With reference to this figure, the construction of the present invention is more easily understood by those skilled in the art. After the mating, the spring contact 4 is moved against the first outer conductor 16, so that the first insulating medium 13 is protected. This is not essential, however, and the spring contact 14 may also be spaced from the first outer conductor 16.

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 decorations can be made without departing from the basic principle of the present invention, and these modifications and decorations are also considered to be within the scope of the present invention.
