Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of connectors, and in particular to a contact member for a connector.BACKGROUND

[0002] In the connector industry, a contact member has always been the most important part on the connector, which is directly related to reliability of connection performance of the connector.

[0003] FIG. 1 shows a structure of an existing connector, which uses a sheet-type contact member, having a front end as a contact area, and the contact area is bent and formed with a rear end of the contact member. In order to improve production efficiency of the contact members and connectors and reduce costs of products, an increasing number of manufacturers are opting to produce the sheet-type contact members by stamping molds. However, in stamping for producing the sheet-type contact member, the contact area at the front end of the contact member is formed by bending a strip material through a mold. Due to certain inherent elasticity of the material, a GAP value of the bent contact member is unstable and difficult to control, meaning a spacing dimension of a contact in the contact area is unstable and difficult to control. This leads to poor contact stability and reliability of the contact member, as well as difficulty in controlling a plugging force of the connector in plugging.SUMMARY

[0004] An objective of the utility model is to provide a contact member. Optimizing a structure of the contact member ensures its well forming stability and improves its contact stability and reliability.

[0005] In order to achieve the above objective, the utility model uses the technical solution as follows: a contact member includes a conductive sheet, where a protruding contact capable of making a contact to a plug is arranged in a contact area at a front end of the conductive sheet, and a rear end of the conductive sheet forms a termination area for connecting to an external conductive piece; and the contact area of the conductive sheet is coplanar with a middle portion of the conductive sheet.

[0006] Beneficial effects: the fact that the contact area of the conductive sheet is coplanar with the middle portion of the conductive sheet can omit a bending step for the contact area, ensure well stability and easy control of a GAP value of the contact member, and improve the contact stability and reliability of the contact member.

[0007] The contact area of the conductive sheet is arranged as a conductive leaf spring, on which a plurality of conductive spring claws are arranged at intervals, and the protruding contact is arranged at a front end of each conductive spring claw.

[0008] Beneficial effects: each conductive spring claw is provided with the protruding contact for making the contact to the plug, ensuring a sufficient number of the contacts and improving plugging stability of the contact member with the plug in a high-frequency vibration environment.

[0009] Further, the protruding contacts on the plurality of conductive spring claws of one conductive leaf spring are staggered in a plugging direction of the contact member.

[0010] Beneficial effects: in plugging, the plug can sequentially make the contact to the plurality of conductive spring claws, which allows a plugging force in plugging the plug to be dispersed, making plugging smoother.

[0011] The contact member provided by the utility model further includes an outer jacket which is sleeved on the contact area at the front end of the conductive sheet.

[0012] Beneficial effects: arranging the outer jacket can prevent the conductive sheet from powerlessly yielding after multiple uses of the contact member.

[0013] Further, an inner raised rib capable of abutting on the conductive sheet is arranged on an inner side of the outer jacket, and a stopping surface for cooperating with a limiting boss on the conductive sheet to prevent the outer jacket from falling off is arranged at an edge of the inner raised rib.

[0014] Beneficial effects: arrangement of the inner raised rib ensures, on one hand, an overall strength of the outer jacket, and on the other hand, more tightly mating between the outer jacket and the conductive sheet; and cooperation between the stopping surface and the limiting boss can prevent the outer jacket from falling off the conductive sheet.

[0015] Further, an outer raised rib protruding from an outer surface is arranged on the outer surface of the outer jacket; the outer raised rib is attached to an external housing outside the contact member, so that an activity gap is formed between the front end of the contact member and the external housing for allowing the conductive spring claws to spread apart; and a groove capable of forming a convex-concave fit with the external housing to provide a retention force for the contact member is formed in the outer raised rib.

[0016] Beneficial effects: arranging the outer raised rib can provide an activity space for the conductive spring claws spreading apart; while the groove of the outer raised rib is in the convex-concave fit with a protruding element of the external housing, providing a certain retention force for the contact member and thus preventing the contact member from being pushed into the external housing in plugging.

[0017] Further, supporting spring claws are arranged at a front portion of the outer jacket, in one-to-one correspondence to the conductive spring claws, and support outer sides of the corresponding conductive spring claws.

[0018] Beneficial effects: supporting the conductive spring claws by the supporting spring claws can prevent a relaxed stress of the conductive spring claws after multiple times of plugging, which provides a stable normal force to the conductive spring claws.

[0019] Further, a limiting structure for cooperating with the external housing outside the contact member is arranged at an edge of the conductive sheet; and the limiting structure includes a limiting step and / or a limiting curved surface.

[0020] Beneficial effects: cooperation between the limiting structure and the external housing of the contact member can improve stability of the contact member within the external housing. This prevents shaking of the contact member in plugging, and ensures well reliability of plugging the contact member.

[0021] As an implementation, there is one above-mentioned conductive sheet.

[0022] As another implementation, there are two above-mentioned conductive sheets.

[0023] Beneficial effects: the number of the provided conductive sheets can be selected as required by a usage scenario, which meets an application requirement and expands an application range of the utility model.

[0024] Further, a constraining structure for constraining the conductive sheets in a direction perpendicular to plate surfaces of the conductive sheets are arranged at portions, opposite to each other, of the two conductive sheets; and the constraining structure is a protruding structure provided on inner sides of the plate surfaces of the conductive sheets, or is a fastener or a bent portion connecting the two conductive sheets, the bent portion being integrally formed with the two conductive sheets.

[0025] Beneficial effects: the constraining structure can prevent significant shaking of the conductive sheets in plugging, especially prevent large-amplitude shaking of the contact area, thereby further ensuring stability of a GAP value of the contact member.

[0026] As yet an implementation, there is one conductive sheet which is of a plate structure; the protruding contacts are formed, by recesses, in the contact area at the front end; and the conductive sheets are wrapped by the outer jacket.

[0027] Beneficial effects: a structure of the provided conductive sheets can be selected as required by the usage scenario, which meets the application requirement and expands the application range of the utility model. Arranging the outer jacket can prevent the conductive sheets from powerlessly yielding after multiple uses of the contact member.

[0028] The utility model has the following beneficial effects: the utility model optimizes and adjusts the structure of the conductive sheet, to omit a bending step for the contact area in forming the conductive sheet. This ensures the stability of the GAP value of the contact member, thereby improving the contact stability and reliability of the contact member. Also, arranging the constraining structure of the contact member can prevent large-amplitude shaking of the contact area in plugging, further ensuring the stability of the GAP value of the contact member.BRIEF DESCRIPTION OF DRAWINGS

[0031] The utility model is further described in detail below in combination with the drawings and the embodiments, which is not used as a basis for limiting the utility model.Embodiment 1

[0032] Referring to FIGs. 2 and 3, a contact member includes two conductive sheets 1 and an outer jacket 2 mounted on the two conductive sheets 1. Each conductive sheet 1 has a front end as a contact area 11, a middle portion as a transition area 12, and a rear end as a termination area 13. The contact area 11 is used for making a plugging contact to a plug; and the termination area 13 is used for connecting to an external conductive piece with a connecting structure including, but not limited to, crimping, welding, bolting, etc. The outer jacket 2 wraps around the contact area 11, and is provided with a socket for the plug to plug in.

[0033] As a choice, as shown in FIG. 5, the two conductive sheets can be integrally formed by stamping a strip material. At this time, the termination areas 13 of the two conductive sheets are bent and then connected together. After the terminal areas 13 are bent, the plate surfaces of the two contact areas 11 at the front ends of the two conductive sheets 1 face each other, and plate surfaces of the transition areas 12 at the middle portions of the two conductive sheets face each other.

[0034] As another choice, as shown in FIG. 6, the termination areas of the two conductive sheets 1 are riveted together. Also, the plate surfaces of the two contact areas 11 of the two conductive sheets 1 face each other, and plate surfaces of the transition areas 12 at the middle portions of the two conductive sheets face each other.

[0035] As other connecting ways, the termination areas of the two conductive sheets can also be spliced and formed by a way such as press-fitting, welding, and threaded connection.

[0036] As shown in FIG. 4, the contact area 11 of the conductive sheet 1 is arranged as a conductive leaf spring 111 and has a plurality of conductive spring claws 112 arranged on the conductive leaf spring 111 at intervals. A protruding contact capable is arranged at a front end of each conductive spring claw for making a plugging contact to a plug. A root of the conductive spring claw 112 is coplanar with the plate surface of the corresponding transition area, so as not to be bent relative to the plate surface of the transition area 12, thereby omitting the bending step for the contact area 11. This ensures the stability and easy control of the GAP value of the contact member, and improves the contact stability and reliability of the contact member.

[0037] The protruding contacts 113 on the plurality of conductive spring claws 112 of one conductive sheet 1 are staggered in a plugging direction of the contact member. In this way, the plug can sequentially make the contact to the plurality of conductive spring claws 112, which allows a plugging force in plugging the plug to be dispersed, making plugging smoother. Staggered arrangement can be referred to FIG. 4, where the protruding contacts 113 located on two edges in a width direction of the conductive leaf spring are positioned forward, and the protruding contacts 113 located at a middle portion are positioned rearward. That is, the conductive spring claws 112 on the two edges in the width direction are longest, the conductive spring claws 112 at the middle portion are shortest, and lengths of the other conductive spring claws 112 decrease successively from the edges toward the middle portion. Similarly, the staggered arrangement of the protruding contacts 113 can also be achieved by using an arrangement way opposite to that shown in FIG. 4.

[0038] The plate surfaces of the transition areas 12 of the two conductive sheets 1 are opposite to each other, and inner sides of the two plate surfaces are in contact mating by means of a protruding structure as shown in FIG. 3, thereby preventing large-amplitude shaking of the contact areas 11 at the front ends and further ensuring the stability of the GAP value of the contact member. In addition to the protruding structure mating way shown in FIG. 3, ways such as bending mating and fastener connection can also be used to constrain the contact areas 11 at the front ends. Among them, bending mating refers to connecting the two conductive sheets 1 at the transition areas 12 by means of a bent portion.

[0039] Continuing to refer to FIG. 4, a limiting step 121 and a limiting curved surface 122 are arranged on two sides of the plate surface, located in the transition area, of the conductive sheet 1, where the limiting step 121 is located in front of the limiting curved surface 122. The limiting curved surface 122 is a section of wavy surface in this embodiment, and may also be a curved surface in other shapes in other implementations. Cooperation of the limiting step 121 and the limiting curved surface 122 with the external housing of the contact member can improve the stability of the contact member within the external housing. This prevents shaking of the contact member in plugging, and ensures well reliability of plugging the contact member.

[0040] In other implementations, it can also provide only the limiting step 121 or the limiting curved surface 122 as required by the usage scenario.

[0041] As shown in FIG. 4, at a boundary between the transition area 12 and the contact area 11, a limiting boss 123 is provided. The limiting boss 123 is arranged on an outer plate surface of the conductive sheet 1 and located within the transition area 12, primarily used for mounting and fixing the outer jacket 2.

[0042] The outer jacket 2 is sleeved on the front end of the contact member, and its function is to ensure an overall strength of a socket of a sheet-type contact member. Specifically, the outer jacket 2 is sleeved on the contact areas 11 of the two conductive sheets 1. A structure of the outer jacket 2 is shown in FIG. 7, as follows: a front portion of the outer jacket 2 is the supporting spring claws 21, in one-to-one correspondence to the conductive spring claws 112 of the conductive sheet 1; and the conductive spring claws 21 support outer sides of the conductive spring claws 112, which can prevent relaxed stress of the conductive spring claws 112 after multiple times of plugging, thereby providing a stable normal force to the conductive spring claws 112. Arranging a protruding inner raised rib 25 on an inner side of a rear portion of the outer jacket 2 can both ensure an overall strength of the outer jacket 2 and more tightly mating between the outer jacket 2 and the conductive sheet 1. Also, forming a notch in a front edge of the inner raised rib 25 forms a stopping surface 23 stuck on the limiting boss 123; and cooperation between the stopping surface 23 and the limiting boss 123 can prevent the outer jacket 2 from falling off the conductive sheet.

[0043] Further, an outer raised rib 24 is also provided on an outer surface of the outer jacket 2, protruding from the surface of the outer jacket 2. As shown in FIG. 8, when the contact member is charged into the external housing, the outer raised rib 24 is attached to the external housing, forming an activity gap 26 between the contact area 11 and the external housing. This ensures that the front end of the conductive sheet 1 can spread apart after the plug is plugged into the contact area 11. More further, a notch is formed in a rear edge of the outer raised rib 24, thereby forming a groove 22 that can be in a convex-concave fit with a protruding portion in the external housing. This provides a certain retention force for the contact member and prevents the contact member from being pushed into the external housing in plugging the contact member.Embodiment 2

[0044] This embodiment is a variation based on embodiment 1, aiming to meet the needs of application scenarios different from those in embodiment 1. In this embodiment, there is one conductive sheet, whose structure is the same as that in embodiment 1. As shown in FIG. 9 and FIG. 10, a length of the conductive spring claw 112 can be specifically set as actually needed. The outer jacket, as described in embodiment 1, is mounted outside the conductive sheet.Embodiment 3

[0045] This embodiment proposes another structural form of the conductive sheet. The conductive sheet 1 is integrally of a plate structure, and a row of protruding contacts are provided in the contact area 11 at its front end, with a rear side of each protruding contact being a depressed recess 114. The outer jacket (not shown in the drawing) is press fitted on and wrapped around the contact area 11. The outer jacket is attached to and makes a contact to a surface where the recesses are located, providing support for the protruding contacts and preventing the conductive sheet from powerlessly yielding after long-term use. Similar to embodiment 1, the outer raised rib is arranged on the outer surface of the outer jacket. The outer raised rib is attached to the external housing outside the contact member, so that the activity gap is formed between the front end of the contact member and the external housing to allow the contact area to spread apart.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not for limitation. Those of ordinary skill in the art should understand that the specific implementations of the utility model may be modified or replaced by equivalents with reference to the above embodiments. These modifications or equivalents without departing from the spirit and scope of the utility model all should be included in the scope of the claims applying for approval.

[0031] The utility model is further described in detail below in combination with the drawings and the embodiments, which is not used as a basis for limiting the utility model.Embodiment 1

[0032] Referring to FIGs. 2 and 3, a contact member includes two conductive sheets 1 and an outer jacket 2 mounted on the two conductive sheets 1. Each conductive sheet 1 has a front end as a contact area 11, a middle portion as a transition area 12, and a rear end as a termination area 13. The contact area 11 is used for making a plugging contact to a plug; and the termination area 13 is used for connecting to an external conductive piece with a connecting structure including, but not limited to, crimping, welding, bolting, etc. The outer jacket 2 wraps around the contact area 11, and is provided with a socket for the plug to plug in.

[0033] As a choice, as shown in FIG. 5, the two conductive sheets can be integrally formed by stamping a strip material. At this time, the termination areas 13 of the two conductive sheets are bent and then connected together. After the terminal areas 13 are bent, the plate surfaces of the two contact areas 11 at the front ends of the two conductive sheets 1 face each other, and plate surfaces of the transition areas 12 at the middle portions of the two conductive sheets face each other.

[0034] As another choice, as shown in FIG. 6, the termination areas of the two conductive sheets 1 are riveted together. Also, the plate surfaces of the two contact areas 11 of the two conductive sheets 1 face each other, and plate surfaces of the transition areas 12 at the middle portions of the two conductive sheets face each other.

[0035] As other connecting ways, the termination areas of the two conductive sheets can also be spliced and formed by a way such as press-fitting, welding, and threaded connection.

[0036] As shown in FIG. 4, the contact area 11 of the conductive sheet 1 is arranged as a conductive leaf spring 111 and has a plurality of conductive spring claws 112 arranged on the conductive leaf spring 111 at intervals. A protruding contact capable is arranged at a front end of each conductive spring claw for making a plugging contact to a plug. A root of the conductive spring claw 112 is coplanar with the plate surface of the corresponding transition area, so as not to be bent relative to the plate surface of the transition area 12, thereby omitting the bending step for the contact area 11. This ensures the stability and easy control of the GAP value of the contact member, and improves the contact stability and reliability of the contact member.

[0037] The protruding contacts 113 on the plurality of conductive spring claws 112 of one conductive sheet 1 are staggered in a plugging direction of the contact member. In this way, the plug can sequentially make the contact to the plurality of conductive spring claws 112, which allows a plugging force in plugging the plug to be dispersed, making plugging smoother. Staggered arrangement can be referred to FIG. 4, where the protruding contacts 113 located on two edges in a width direction of the conductive leaf spring are positioned forward, and the protruding contacts 113 located at a middle portion are positioned rearward. That is, the conductive spring claws 112 on the two edges in the width direction are longest, the conductive spring claws 112 at the middle portion are shortest, and lengths of the other conductive spring claws 112 decrease successively from the edges toward the middle portion. Similarly, the staggered arrangement of the protruding contacts 113 can also be achieved by using an arrangement way opposite to that shown in FIG. 4.

[0038] The plate surfaces of the transition areas 12 of the two conductive sheets 1 are opposite to each other, and inner sides of the two plate surfaces are in contact mating by means of a protruding structure as shown in FIG. 3, thereby preventing large-amplitude shaking of the contact areas 11 at the front ends and further ensuring the stability of the GAP value of the contact member. In addition to the protruding structure mating way shown in FIG. 3, ways such as bending mating and fastener connection can also be used to constrain the contact areas 11 at the front ends. Among them, bending mating refers to connecting the two conductive sheets 1 at the transition areas 12 by means of a bent portion.

[0039] Continuing to refer to FIG. 4, a limiting step 121 and a limiting curved surface 122 are arranged on two sides of the plate surface, located in the transition area, of the conductive sheet 1, where the limiting step 121 is located in front of the limiting curved surface 122. The limiting curved surface 122 is a section of wavy surface in this embodiment, and may also be a curved surface in other shapes in other implementations. Cooperation of the limiting step 121 and the limiting curved surface 122 with the external housing of the contact member can improve the stability of the contact member within the external housing. This prevents shaking of the contact member in plugging, and ensures well reliability of plugging the contact member.

[0040] In other implementations, it can also provide only the limiting step 121 or the limiting curved surface 122 as required by the usage scenario.

[0041] As shown in FIG. 4, at a boundary between the transition area 12 and the contact area 11, a limiting boss 123 is provided. The limiting boss 123 is arranged on an outer plate surface of the conductive sheet 1 and located within the transition area 12, primarily used for mounting and fixing the outer jacket 2.

[0042] The outer jacket 2 is sleeved on the front end of the contact member, and its function is to ensure an overall strength of a socket of a sheet-type contact member. Specifically, the outer jacket 2 is sleeved on the contact areas 11 of the two conductive sheets 1. A structure of the outer jacket 2 is shown in FIG. 7, as follows: a front portion of the outer jacket 2 is the supporting spring claws 21, in one-to-one correspondence to the conductive spring claws 112 of the conductive sheet 1; and the conductive spring claws 21 support outer sides of the conductive spring claws 112, which can prevent relaxed stress of the conductive spring claws 112 after multiple times of plugging, thereby providing a stable normal force to the conductive spring claws 112. Arranging a protruding inner raised rib 25 on an inner side of a rear portion of the outer jacket 2 can both ensure an overall strength of the outer jacket 2 and more tightly mating between the outer jacket 2 and the conductive sheet 1. Also, forming a notch in a front edge of the inner raised rib 25 forms a stopping surface 23 stuck on the limiting boss 123; and cooperation between the stopping surface 23 and the limiting boss 123 can prevent the outer jacket 2 from falling off the conductive sheet.

[0043] Further, an outer raised rib 24 is also provided on an outer surface of the outer jacket 2, protruding from the surface of the outer jacket 2. As shown in FIG. 8, when the contact member is charged into the external housing, the outer raised rib 24 is attached to the external housing, forming an activity gap 26 between the contact area 11 and the external housing. This ensures that the front end of the conductive sheet 1 can spread apart after the plug is plugged into the contact area 11. More further, a notch is formed in a rear edge of the outer raised rib 24, thereby forming a groove 22 that can be in a convex-concave fit with a protruding portion in the external housing. This provides a certain retention force for the contact member and prevents the contact member from being pushed into the external housing in plugging the contact member.Embodiment 2

[0044] This embodiment is a variation based on embodiment 1, aiming to meet the needs of application scenarios different from those in embodiment 1. In this embodiment, there is one conductive sheet, whose structure is the same as that in embodiment 1. As shown in FIG. 9 and FIG. 10, a length of the conductive spring claw 112 can be specifically set as actually needed. The outer jacket, as described in embodiment 1, is mounted outside the conductive sheet.Embodiment 3

[0045] This embodiment proposes another structural form of the conductive sheet. The conductive sheet 1 is integrally of a plate structure, and a row of protruding contacts are provided in the contact area 11 at its front end, with a rear side of each protruding contact being a depressed recess 114. The outer jacket (not shown in the drawing) is press fitted on and wrapped around the contact area 11. The outer jacket is attached to and makes a contact to a surface where the recesses are located, providing support for the protruding contacts and preventing the conductive sheet from powerlessly yielding after long-term use. Similar to embodiment 1, the outer raised rib is arranged on the outer surface of the outer jacket. The outer raised rib is attached to the external housing outside the contact member, so that the activity gap is formed between the front end of the contact member and the external housing to allow the contact area to spread apart.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not for limitation. Those of ordinary skill in the art should understand that the specific implementations of the utility model may be modified or replaced by equivalents with reference to the above embodiments.
