Description

Technical Field

[0001] The utility model relates to a connector with elastic contact. Background Art

[0002] like Figure 1 As shown, based on the design of separating the mechanical reference plane and the electrical reference plane of the 4.3-10 connector, hand-tightened threads and axial push-pull connection forms are allowed for plugging. A tapered surface for plugging guide is designed on the anode connector housing, and the tapered surface has a long length. When the connector is plugged in, it is easy to be skewed, resulting in uneven deformation of the elastic contact piece during plugging. At the same time, when the plugging is not in place, due to the weight of the cable at the rear of the connector, it is very likely that the connector will be skewed and stuck due to non-concentricity. These situations all cause uneven deformation of the elastic contact piece, resulting in uneven and unstable radial electrical contact, so that the first inner conductor (10) and the second inner conductor (20) cannot be stably connected. In view of this, the utility model proposes a connector with elastic contact to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Example:

[0032] like Figure 1-6 As shown, this embodiment provides an elastic contact connector, including a first connector 30 and a second connector 40, wherein the first connector 30 is provided with a connecting sleeve A32, and the second connector 40 is provided with a connecting sleeve B41, wherein the connecting sleeve B41 is sleeved on the outer wall of the connecting sleeve A32, and the connecting sleeve A32 is provided with a plug-in guiding tapered surface 33;

[0033] The inner cavity of the connecting sleeve B41 is provided with a claw-type contact piece 42, and the claw-type contact piece 42 includes a fixed tube 422. A plurality of groups of elastic plates 423 are provided on the fixed tube 422. The elastic plates 423 extend into the inner cavity of the connecting sleeve A32 through the insertion guide conical surface 33. The plurality of groups of elastic plates 423 are in contact with the inner wall of the connecting sleeve A32. An elastic reinforcement ring 60 is provided in the fixed tube 422. The elastic reinforcement ring 60 is in contact with the elastic plate 423 for reinforcement support.

[0034] In this case, a threaded sleeve is rotatably provided on the first connecting head 30, and an external threaded wall is provided on the outer wall of the connecting sleeve B41. The first connecting head 30 and the second connecting head 40 are connected to the external threaded wall through the threaded sleeve for reliable connection. This technology is existing technology and will not be described in detail here.

[0035] In this embodiment, when the connector is connected, the second connector 40 is inserted into the first connector 30, that is, the connecting sleeve B41 is sleeved on the outer wall of the connecting sleeve A32, and the claw-shaped contact piece 42 is extended into the inner cavity of the connecting sleeve A32 through the plug-in guide tapered surface 33, so that the multiple sets of elastic plates 423 are in contact with the inner wall of the connecting sleeve A32;

[0036] When the claw-type contact piece 42 is skewed and unevenly deformed by the insertion of the elastic plate 423 into the guiding tapered surface 33, the elastic plate 423 is reset by its own elastic property, so that the first connector 30 and the second connector 40 are aligned and maintained in a concentric state. When the first connector 30 and the second connector 40 are connected, the stability of the radial electrical contact can be effectively guaranteed. The elastic reinforcement ring 60 provided can reinforce and support the multiple groups of elastic plates 423, thereby improving the reset ability of the elastic plate 423. When the elastic reset ability of the elastic plate 423 itself is insufficient, it is easy to drive the elastic plate 423 to reset, so as to maintain the stability of the radial electrical contact, thereby maintaining the stability of the connection between the first connector 30 and the second connector 40.

[0037] Specifically, the inner cavity of the connecting sleeve A32 is provided with an inner conductor A31;

[0038] The inner cavity of the connecting sleeve B41 is provided with an insulating dielectric block 43, and the insulating dielectric block 43 is provided with an inner conductor B44. The inner conductor A31 and the inner conductor B44 are adapted to each other.

[0041] The elastic plate 423 is provided with a raised contact portion 424 , and the raised contact portion 424 is provided with a placement groove 51 ;

[0042] The positions of the multiple groups of placement grooves 51 match each other, and the multiple groups of placement grooves 51 are combined to form a placement ring groove 50 , and the elastic reinforcement ring 60 is arranged in the multiple groups of placement ring grooves 50 .

[0043] In this embodiment, the elastic plates 423 are arranged in a ring array on the fixed tube 422, which can improve the mechanical strength and stability of the overall structure;

[0044] The placement ring groove 50 formed by combining multiple groups of placement grooves 51 can facilitate the placement of the elastic reinforcement ring 60 and prevent the elastic reinforcement ring 60 from detaching from the multiple groups of elastic plates 423.

[0045] Specifically, the elastic reinforcement ring 60 is provided with a deformation notch 61, so that the elastic reinforcement ring 60 is reduced in radial direction under the action of external force;

[0046] The outer diameter of the elastic reinforcement ring 60 in a natural state is larger than the outer diameter of the placement ring groove 50 .

[0047] In this embodiment, the deformation notch 61 is provided to facilitate the elastic reinforcement ring 60 to deform inwards, so as to facilitate the insertion into the placement ring groove 50;

[0048] Of course, the elastic reinforcement ring 60 can reinforce and support multiple groups of elastic plates 423. The elastic plates 423 can be made of a brass alloy with poor elasticity and low cost, which greatly reduces the cost of the product without affecting electrical contact or losing electrical performance indicators.

[0049] Specifically, a limiting sleeve 70 is provided on the outer wall of the fixed tube 422, and the limiting sleeve 70 is sleeved at the junction where the fixed tube 422 and the elastic plate 423 are connected;

[0050] The inner diameter of the limiting sleeve 70 is larger than the outer diameter of the fixing tube 422 , and the inner wall of the limiting sleeve 70 is tightly fitted with the inner wall of the fixing tube 422 .

[0051] In this embodiment, the limit sleeve 70 is provided to limit the multiple groups of elastic plates 423 to prevent the elastic plates 423 from opening too much and deforming abnormally. By cooperating with the elastic reinforcement ring 60, it can play the role of internal support and external hoop. This structure makes its shape after expansion controllable, ensuring that its elastic force is stable and consistent.

[0052] Specifically, a connecting ring 421 is fixedly provided on the outer wall of the fixing tube 422, and the connecting ring 421 is connected to the inner wall of the connecting sleeve B41.

[0053] In this embodiment, the connection ring 421 is provided to facilitate installation of the fixing tube 422 and the connection sleeve B41.

[0054] Specifically, the fixing tube 422, the connecting ring 421 and the elastic plate 423 are an integrally formed structure;

[0055] The fixing tube 422 , the connecting ring 421 and the elastic plate 423 are all made of brass and electroplated.

[0056] In this embodiment, the fixing tube 422 , the connecting ring 421 and the elastic plate 423 are an integrally formed structure, and are subjected to turning and grooving processes to form a plurality of sets of elastic plates 423 arranged in a ring array.

[0057] Specifically, the elastic reinforcement ring 60 is made of high-strength non-metallic material, and the limiting sleeve 70 is made of polytetrafluoroethylene material.

[0058] In this embodiment, the elastic reinforcement ring 60 is made of high-strength non-metallic material, which can avoid affecting the electrical performance of the product itself.
