The embodiment of the utility model provides a contactor 100, through base 110 to and set up contactor body 120 on base 110, contactor body 120 includes a plurality of conductive parts 122, and conductive part 122 is provided with a plurality of conducting rods 112 on the base 110 towards base 110. When the contactor body 120 is mounted on the base 110, the conductive portion 122 of the contactor body 120 faces the base 110, and the conductive rod 112 of the base 110 is connected to the conductive portion 122 to form an electrical connection path.

As shown in fig. 3, the base 110 includes a bottom plate 114 and connecting members 116 spaced apart from each other on the bottom plate 114, a plurality of conductive rods 112 are respectively disposed through the connecting members 116, and the contactor body 120 is connected to the base 110 through the connecting members 116.

Specifically, the connecting members 116 are spaced apart from each other on the bottom plate 114, and a receiving space is formed between the connecting members 116, and the contactor body 120 may be disposed in the receiving space. Therefore, the contact body 120 can be prevented from being laterally deviated when being connected with the base 110, which is beneficial to improving the stability of the connection. When the contactor body 120 is connected to the base 110 via the connecting member 116, the conductive portion 122 of the contactor body 120 corresponds to the connecting member 116, and the plurality of conductive rods 112 are provided through the connecting member 116, respectively, so that one end of the conductive rod 112 can be connected to the conductive portion 122 of the contactor body 120 when the contactor body 120 is connected to the connecting member 116.

It should be noted that the shape of the connecting member 116 is not particularly limited in this embodiment, as long as the stable connection between the contactor body 120 and the connecting member 116 can be ensured. For example, the opposite sides of the two connecting members 116 may be provided with stepped surfaces, which may limit the contact body 120 in a clamping manner, and may also prevent the contact body 120 from laterally shifting. The external shape of the connecting member 116 may be changed according to the shape of the contactor body 120 so that the contactor body 120 and the connecting member 116 can be stably coupled to each other.

As shown in fig. 4, the connecting member 116 has a hollow structure, and a plurality of partitions 1162 are disposed in an inner cavity of the connecting member 116 to isolate the conductive rods 112 passing through the connecting member 116 from each other.

When the connecting member 116 is provided as a hollow structure, the mass of the connecting member 116 can be reduced, making the contactor 100 lighter as a whole. Since the connecting member 116 has a hollow structure, a plurality of spacers 1162 may be disposed in the hollow cavity formed in the connecting member 116, so as to electrically isolate different conductive rods 112, and increase a creepage distance and an electrical gap, so as to prevent short circuit or electrical interference, thereby improving stability of electrical connection. In addition, the structural strength of the connecting member 116 can be improved by arranging the plurality of partition plates 1162 in the inner cavity of the connecting member 116, so that the overall structure of the contactor 100 is more stable and reliable.

Referring to fig. 4 and 5, the side walls of the connecting member 116 are respectively provided with a notch 1164, the bottom plate 114 is correspondingly provided with a hook 1142, and the connecting member 116 is in snap fit with the hook 1142 through the notch 1164.

Specifically, the connecting member 116 is detachably connected to the bottom plate 114 through a notch 1164 formed on a side wall of the connecting member 116 and a corresponding hook 1142 formed on the bottom plate 114. In the embodiment of the present application, the number of the notches 1164 and the corresponding sets of the hooks 1142 is not particularly limited. As long as a stable connection can be ensured. For example, the notches 1164 and the number of the corresponding sets of hooks 1142 may be two, or three or four, as shown in fig. 5, the embodiment is described with three hooks 1142, since the connectors 116 are spaced on the bottom plate 114, the connectors 116 are distributed on two opposite sides of the bottom plate 114, and when the hooks 1142 are provided on the bottom plate 114, the latching protrusions 1166 of the hooks 1142 are disposed toward the outside, so that when the connectors 116 are provided on the bottom plate 114, the hooks 1142 are located in the cavities of the connectors 116, and the latching protrusions 1166 on the hooks 1142 can be in latching engagement with the notches 1164, and form a stable connection structure.

Referring to fig. 5 again, the hooks 1142 are distributed on the bottom plate 114 in a triangular shape, so that when the connecting member 116 is connected to the bottom plate 114 through the hooks 1142, the hooks 1142 are clamped with the notches 1164 through the clamping protrusions on the hooks 1142, and the hooks 1142 can limit the connecting member 116, thereby preventing the connecting member 116 and the bottom plate 114 from shifting laterally. The hooks 1142 are arranged in a triangular distribution mode, so that the six degrees of freedom of the connecting piece 116 can be limited, the stability of connection between the connecting piece 116 and the bottom plate 114 is improved, and the assembly connection between the connecting piece 116 and the bottom plate 114 is facilitated.

As shown in fig. 3, in an alternative of this embodiment, an accommodating space is formed between the connecting pieces 116, protrusions 1166 are respectively disposed on opposite sides of the connecting pieces 116, grooves 124 are correspondingly disposed on opposite sides of the contactor body 120, and the contactor body 120 is in snap fit with the protrusions 1166 through the grooves 124.

Adopt above-mentioned structure, can dismantle between contactor body 120 and the connecting piece 116 and be connected, when contactor body 120 inserted the accommodation space, recess 124 on the contactor body 120 and the protruding 1166 joint cooperation on the connecting piece 116, because contactor body 120 belongs to electrical wear spare, when the life-span end, accessible recess 124 and protruding 1166 relieved the complex form in order to change, are favorable to saving the change time, reduce the operation degree of difficulty.

It can be understood that, in another alternative of this embodiment, an accommodating space is formed between the connecting pieces 116, the opposite sides of the connecting pieces 116 are respectively provided with a groove 124, the opposite sides of the contactor body 120 are respectively and correspondingly provided with a protrusion 1166, and the contactor body 120 is in snap fit with the groove 124 through the protrusion 1166, so as to achieve the purpose of detachable connection between the contactor body 120 and the connecting pieces 116.

It should be noted that the shape and arrangement of the protrusion 1166 and the groove 124 are not particularly limited in this embodiment, as long as a stable connection can be ensured. For example, the protrusions 1166 and the recesses 124 may be provided in four sets, and if two protrusions 1166 are provided on each connecting member 116, two recesses 124 are provided on the side of the contactor body 120 corresponding to the protrusions 1166, so as to achieve a stable fitting relationship. The protrusion 1166 may be configured to be triangular, trapezoidal, or arc-shaped, and the groove 124 may be adapted and modified according to the structure of the protrusion 1166 as long as stable connection is ensured.

As shown in fig. 6, in an alternative embodiment of the present application, a bent portion 1122 is provided at one end of the conductive rod 112 connected to the conductive portion 122, and the conductive rod 112 is connected to the conductive portion 122 through the bent portion 1122.

Thus, the contact area of the connection portion between the conductive rod 112 and the conductive portion 122 can be increased, and the problem of excessive heat generation due to too small contact area caused by the loose contact when the end of the conductive rod 112 contacting the conductive portion 122 is a cross section can be avoided. The bending portion 1122 provided at the end of the conductive rod 112 connected to the conductive portion 122 enables the conductive rod 112 and the conductive portion 122 to be in stable electrical connection, which is beneficial to reducing problems such as poor contact and improving stability during use.

Optionally, the conductive rod 112 includes a rod 1121 and an elastic portion connected to the rod 1121, so that the conductive rod 112 is elastically connected to the conductive portion 122. Thus, when the plurality of conductive bars 112 are connected to the plurality of conductive portions 122 in one-to-one correspondence, it is possible to avoid that some of the conductive bars 112 cannot be stably connected to the conductive portions 122 when the heights of the respective conductive bars 112 are not uniform. In this way, by elastic deformation of the conductive rods 112, the difference in deformation amount generated when the conductive rods 112 are in contact with the conductive part 122 can be used to compensate for the difference in length due to process errors, thereby ensuring reliability of electrical connection.

As shown in fig. 7, in an alternative embodiment of the present application, the elastic portion is a clamping terminal 1126, the clamping terminal 1126 is located at one end of the rod 1121, and the conductive rod 112 is connected to the conductive portion 122 through the clamping terminal 1126.

Specifically, the present embodiment does not specifically limit the connection form between the clamping terminal 1126 and the rod 1121, as long as the electrical connection between the clamping terminal 1126 and the rod 1121 can be achieved. For example, the clamping terminal 1126 may be a clamping spring and welded to the rod 1121 to form a stable connection structure. When the clamping terminal 1126 is adopted to electrically connect with the conductive portion 122, the conductive portion 122 may be a strip-shaped conductive sheet or a cylindrical conductive rod, and when the conductive portion 122 is matched with the clamping terminal 1126, the conductive portion 122 extends into the clamping area to deform the clamping terminal 1126 under a force, and when the clamping terminal 1126 recovers elastic deformation, the conductive portion 122 is clamped by the clamping terminal 1126, so that a stable electrical connection path is formed with the conductive rod 112.

Referring to fig. 6, in another alternative embodiment of the present application, the elastic portion is a bent structure 1124, and the rod 1121 is connected by at least one bent structure 1124.

It can be understood that when the conductive rod 112 is abutted against the conductive part 122 to form an electrical connection relationship, a certain abutting force needs to be accumulated at the abutting part in order to ensure the stability of the connection part. When the elastic portion is the bending structure 1124, the conductive rod 112 has a certain deformation amount when receiving the abutting force, and the conductive rod 112 can form a stable connection relationship with the conductive portion 122 in the process of recovering the elastic deformation. The conductive rod 112 includes at least one bending structure 1124, and since the connecting member 116 is a hollow structure, the bending structure 1124 can elastically deform in the connecting member 116, and with the above structure, in the process of electrically connecting the conductive rod 112 and the conductive portion 122, it can be avoided that part of the conductive rod 112 cannot be effectively contacted due to the error in the height of part of the conductive rod 112, and when one end of the conductive rods 112 is connected with the conductive portions 122 in a one-to-one correspondence, the reliability of the connection relationship at each position can be ensured.

It should be noted that the embodiment of the present application does not specifically limit the protruding length of the conductive rod 112 and the structural form of the conductive part 122, as long as stable connection can be ensured. For example, the end of the conductive rod 112 connected to the conductive portion 122 may extend out of the connecting component 116 and connect to the conductive portion 122. The end of the conductive rod 112 connected to the conductive portion 122 may also be located within the connector 116, and the conductive portion 122 may be lengthened to electrically connect the conductive portion 122 to the conductive rod 112.

As shown in fig. 5, the side of the base plate 114 facing the circuit board mounting is provided with a cutout 1144. Thus, when the other ends of the conductive rods 112 are connected to the circuit board, the bottom plate 114 can be in smooth contact with the circuit board, which is beneficial to ensuring the stability of the contactor 100 when connected to the circuit board.

In an alternative of this embodiment, the conductive rod 112 includes a primary loop conductive rod and a secondary loop conductive rod, and the current through the primary loop conductive rod is greater than the current through the secondary loop conductive rod. Thus, the cross-section of the main loop conductor bar can be made larger than that of the auxiliary loop conductor bar, so as to ensure that the heat generation of the conductor bar 112 is reduced when current passes through the conductor bar 112. In addition, the shapes of the main loop conductor bar and the auxiliary loop conductor bar may be set to the same shape, or different shapes. When the main loop conducting rod and the auxiliary loop conducting rod are in different shapes, the auxiliary loop conducting rod has lower requirements on deformation due to smaller current passing through the auxiliary loop conducting rod, and can simplify the shape. For example, the main loop conductive rod may have a plurality of bending structures 1124, and the auxiliary loop conductive rod may adopt only one bending structure 1124, as long as the stability of the connection can be ensured.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
