Description

Technical Field

[0001] This utility model relates to the field of female connectors, specifically to a female connector. Background Technology

[0002] A female connector is a type of electronic connector that contains one or more contacts with several elastic springs that receive and engage the pins of the mating male connector.

[0003] The existing female connector cannot simultaneously constrain the degree of elastic deformation of several elastic springs when the pin is inserted between several elastic springs each time. After the pin is inserted between several elastic springs multiple times, it cannot prevent the elastic springs from undergoing plastic deformation, thus failing to extend the service life of the elastic springs. It also cannot prevent several elastic springs from failing to make stable contact with the pin after the pin is inserted between several elastic springs multiple times. When the pin is inserted between several elastic springs and in a vibrating environment, it cannot simultaneously provide radial support to the outside of several elastic springs. When the pin is inserted between several elastic springs and in a vibrating environment, it cannot improve the contact ability between the pin and several elastic springs, and cannot prevent the interruption of the contact between the pin and several elastic springs.

[0004] The purpose of this invention is to design a female connector to address the problems existing in the prior art. Utility Model Content

[0026] To facilitate understanding by those skilled in the art, the structure of this utility model will now be described in further detail with reference to the accompanying drawings: refer to Figure 1-5 A female connector, comprising: A female connector base 1 is provided with a plurality of mounting slots 2, and a contact element is provided on the female connector base 1 and located in the mounting slots 2; The contact element includes a contact element body 3, which is disposed on the female connector seat 1 and located in the mounting groove 2. Several elastic springs 4 are provided at equal angles on the top of the contact element body 3. A constraint support sleeve 5 is provided on the contact element body 3 and on the outside between the elastic springs 4. The constraint support sleeve 5 is used to simultaneously constrain the degree of elastic deformation of several elastic springs 4 when the needle is inserted between several elastic springs 4 each time, so as to prevent the elastic springs 4 from undergoing plastic deformation after the needle is inserted between several elastic springs 4 multiple times, thereby extending the service life of the elastic springs 4 and preventing the elastic springs 4 from failing to make stable contact with the needle after the needle is inserted between several elastic springs 4 multiple times. The constraint radial support sleeve 5 is used to provide radial support to the outside of the elastic springs 4 when the pin is inserted between the elastic springs 4 and in a vibration environment, so as to improve the contact ability between the pin and the elastic springs 4 and prevent the contact between the pin and the elastic springs 4 from being interrupted.

[0027] The top end of the constraint support sleeve 5 is provided with a guide alignment part 6.

[0028] The guide alignment part 6 is used to guide the pin before it is inserted between several elastic springs 4, so that the pin is aligned and smoothly inserted between several elastic springs 4, thereby preventing the pin from directly hitting the top of the elastic spring 4 and causing the top of the elastic spring 4 to be deformed and damaged.

[0029] The bottom end of the constraint support sleeve 5 is provided with several anchoring protrusions 7 at equal angular intervals, and the outside of the contact body 3 is provided with anchoring grooves 8 that simultaneously cooperate with several of the anchoring protrusions 7.

[0030] The combination of several anchoring protrusions 7 and anchoring grooves 8 effectively prevents the constraint radial support sleeve 5 from moving axially or loosening relative to the contact body 3, and effectively prevents the constraint radial support sleeve 5 from rotating on the contact body 3.

[0031] Several elastic mounting limiting plates 9 are provided at equal angular intervals on the outside of the contact body 3 and below the constraint radial support sleeve 5, and a limiting part 10 is provided on the outside of the contact body 3 and below the several elastic mounting limiting plates 9. An installation limiting ring seat 11 is provided on the female connector seat 1 and located in the mounting groove 2. The installation limiting ring seat 11 is located above the limiting part 10 and below the plurality of elastic mounting limiting plates 9.

[0032] When the contact enters the mounting groove 2, several elastic mounting limit plates 9 undergo elastic deformation, thereby allowing the contact to move to a predetermined position. The contact will not detach from the mounting groove 2 through the cooperation of several elastic mounting limit plates 9, mounting limit ring seat 11, and limit part 10.

[0033] Several elastic mounting limiting plates 9 are disposed on the outside of the contact body 3 via elastic connecting plates 12. The elastic connecting plates 12 are provided with notches 13, and the outside of the contact body 3 is provided with limiting grooves 14 that cooperate with the elastic connecting plates 12.

[0034] The limiting groove 14 is used to limit the elastic connecting plate 12 to the outside of the contact body 3, preventing the elastic connecting plate 12 from moving along the axial direction of the contact body 3; the notch 13 facilitates the installation of the elastic connecting plate 12 on the contact body 3.

[0035] The bottom end face of the contact body 3 is provided with a wire receiving hole 15.

[0036] The contact body 3 is provided with a multi-directional pressure device that cooperates with the wire receiving hole 15, and the contact body 3 is provided with a sway protection device located at the inlet of the wire receiving hole 15. The multi-directional pressure device is used to apply multiple spirally distributed pressure points to the wire located in the wire receiving hole 15 after the wire receiving hole 15 has been received, so as to improve the wire's resistance to pulling in the wire receiving hole 15 and thus prevent the wire from being pulled out of the wire receiving hole 15. The anti-sway protection device is used to limit the wire when the multi-directional pressure device applies multiple spirally distributed pressure points to the wire located in the wire hole 15 and the wire is pulled, so as to cooperate with the multi-directional pressure device to reduce the degree of wire sway, thereby maintaining the stability of the wire and further improving the wire's resistance to pulling in the wire hole 15. The anti-sway protection device is used to seal the inlet of the wire receiving hole 15 after the multi-directional pressure device applies multiple spirally distributed pressure points to the wire located in the wire receiving hole 15, so as to prevent dust and moisture from entering the wire receiving hole 15.

[0037] The multi-directional pressure device includes several pressure holes 16, which are spirally arranged on the contact body 3 and located outside the wire receiving hole 15. The pressure holes 16 are connected to the wire receiving hole 15. A pressure bolt 17 is provided in each pressure hole 16, and a friction-enhancing pad 18 is provided in the wire receiving hole 15 at a position opposite to the pressure hole 16. The friction-enhancing pad 18 is used to increase the friction between the wire and the contact body 3 when the pressure bolt 17 applies a clamping force to the wire. The anti-sway protection device includes an auxiliary seat 19, which is detachably mounted on the contact body 3 and located at the inlet of the wire receiving hole 15. The inner wall of the auxiliary seat 19 is provided with a loading / unloading groove 20, and an elastic ring block 21 is provided within the loading / unloading groove 20. The inner diameter of the elastic ring block 21 is smaller than the inner diameter of the wire receiving hole 15. The auxiliary seat 19 is threadedly connected to the contact body 3.

[0038] The female connector seat 1 is provided with grounding plates 22 at both the left and right ends. Several connecting bolts 23 are provided on the grounding plates 22, and a grounding wire assembly 24 is provided in the middle of the grounding plates 22.

[0039] Several connecting bolts 23 are used to mate with the fastener to install the female connector seat 1 onto the fastener; the grounding wire assembly 24 is used to lock the ground wire.
