Description

Technical Field

[0001] The utility model belongs to the field of electrical connectors, and particularly relates to a power contact and a socket connector. Background Art

[0002] The electrical connectors used in new energy vehicles are core components for realizing circuit conduction and signal transmission. When in use, the plug connector and the socket connector are paired and inserted. Among them, the socket connector is usually fixed on the box body of the installed device. The socket connector specifically includes a housing, an insulator, a contact, etc. One end of the contact is used to be adaptively connected to the socket connector, and the other end is used to be connected to the conductive component (such as a PCB board) inside the box body. The housing is used to be fixed on the box body, or the housing is directly composed of a part of the box body.

[0003] As can be seen from the above introduction, the installation position of the socket connector is mainly affected by the box body. If the position accuracy of the conductive component inside the box body is poor, it is easy to cause a large deviation in the relative position between the contact and the conductive component. The contacts of the existing socket connectors are generally of a straight type or a right-angled bent type structure, and almost all are covered in the insulator, making it difficult to deform or change the position. In the case where the position accuracy of the conductive component is poor, it is easy to cause the contact to be unable to be normally connected to the conductive component. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a power contact to solve the technical problem that the contact of the connector in the prior art is difficult to be normally connected to the conductive component with errors. The purpose of the utility model is also to provide a socket connector to solve the same technical problem.

[0005] To achieve the above purpose, the technical solution of the power contact provided by the utility model is:

[0006] A power contact, one end of the power contact is a plug connection end for connecting with a mating plug connector, and the other end is a component connection end for connecting with a conductive component inside the equipment box body. A bending compensation part exposed outside the insulator of the connector during use is provided between the plug connection end and the component connection end. The bending compensation part has at least three compensation segments with continuous bends. The wide surfaces of at least three compensation segments are respectively perpendicular to the left-right direction, perpendicular to the up-down direction, and at an angle with the front-back direction.

[0007] As a further improvement, the wide surface of the plug connection end of the power contact is perpendicular to the left-right direction, and the wide surfaces of the first three compensation segments are perpendicular to the left-right direction, perpendicular to the up-down direction, and at an angle with the front-back direction in sequence from front to back.

[0008] As a further improvement, the wide surface of the component connection end of the power contact forms an angle with the front-rear direction, and the bending compensation part includes four compensation segments. The wide surfaces of these four segments are perpendicular to the left-right direction, perpendicular to the up-down direction, form an angle with the front-rear direction, and are perpendicular to the up-down direction in sequence from front to back.

[0009] As a further improvement, the component connection end is provided with a forced-fitting structure for press-fitting and inserting a pre-fixed insulating part configured for the connector.

[0010] As a further improvement, the forced-fitting structure is a barbed structure.

[0011] The utility model belongs to an improved invention creation, and its beneficial effects are as follows: When the power contact in the utility model is applied to a plug connector, since there is a bending compensation part between the two ends and the bending compensation part is exposed, when connecting to the conductive component inside the equipment box body, the actual position of the component connection end can be adjusted by using the elastic deformation of the bending compensation part itself according to the actual installation position of the conductive component. Specifically, one segment with a wide surface perpendicular to the left-right direction in the bending compensation part can swing and deform left and right, one segment perpendicular to the up-down direction can swing and deform up and down, and one segment forming an angle with the front-rear direction can swing and deform front and back. No matter in which direction there is an installation error of the conductive component, the bending compensation part can adapt to the deformation to compensate for the error, ensuring that the socket connector can be normally connected to the conductive component and reducing the installation difficulty.

[0012] To achieve the above object, the technical solution of the socket connector provided by the utility model is:

[0013] A socket connector includes a housing, an insulator is fixed on the housing, a power contact is fixed on the insulator. One end of the power contact is a plug connection end for connecting to a mating plug connector, and the other end is a component connection end for connecting to a conductive component inside the equipment box body. A bending compensation part that is exposed outside the insulator of the connector during use is provided between the plug connection end and the component connection end. The bending compensation part has at least three continuously bent compensation segments, and the wide surfaces of at least three compensation segments are perpendicular to the left-right direction, perpendicular to the up-down direction, and form an angle with the front-rear direction respectively.

[0014] As a further improvement, the power contacts are arranged in pairs, and in each pair of power contacts, the bending compensation part has a part bent in a direction away from each other.

[0015] As a further improvement, the socket connector further includes a pre-fixed insulating part for integrally pre-fixing the component connection ends of each power contact. The component connection ends of each power contact are all provided with a forced-fitting structure and are press-fitted and inserted into the pre-fixed insulating part through the forced-fitting structure.

[0016] As a further improvement, the forced-fitting structure is a barbed structure.

[0017] As a further improvement, the wide surface of the plug connection end of the power contact is perpendicular to the left - right direction, and the wide surfaces of the first three compensation segments are perpendicular to the left - right direction, perpendicular to the up - down direction, and at an angle to the front - back direction in sequence from front to back.

[0018] As a further improvement, the wide surface of the component connection end of the power contact is at an angle to the front - back direction, and the bending compensation part includes four compensation segments. The wide surfaces of these four segments are perpendicular to the left - right direction, perpendicular to the up - down direction, at an angle to the front - back direction, and perpendicular to the up - down direction in sequence from front to back.

[0019] The utility model belongs to an improved invention. Its beneficial effects are as follows: Different from the prior art, there is a bending compensation part between the two ends of the power contact in the socket connector, and the bending compensation part is exposed. When connecting to the conductive component inside the equipment box, the actual position of the component connection end can be adjusted by using the elastic deformation of the bending compensation part according to the actual installation position of the conductive component. Specifically, one segment with a wide surface perpendicular to the left - right direction in the bending compensation part can swing left - right, one segment perpendicular to the up - down direction can swing up - down, and one segment at an angle to the front - back direction can swing front - back. No matter which direction there is an installation error in the conductive component, the bending compensation part can adapt to the deformation to compensate for the error, ensuring that the socket connector can be normally connected to the conductive component and reducing the installation difficulty.

[0026] To provide a "floating" socket connector that can be normally installed even when there is a positional error in the conductive components inside the device, the basic technical concept of the present utility model is to provide a bending part on the power contact that can elastically deform in different directions and expose this bending part outside the insulator. When assembling the socket connector, the bending part can elastically deform by itself and is not "constrained" by the insulator. In this way, the power contact can be flexibly adjusted according to the actual position of the conductive components to compensate for errors, and then the normal connection between the contact and the conductive components can be achieved.

[0027] Based on the above concept, the present utility model will be further described in detail below in conjunction with embodiments.

[0028] Specific embodiments of the socket connector provided by the present utility model:

[0029] The socket connector provided in this embodiment is as a whole as Figure 1 and Figure 2 shown, including a housing 1. The housing 1 serves as the installation basis of the socket connector and can be fixed to the box body of the device. The device can specifically be a battery pack, a PDU wiring device, a DC / DC device, etc. There is a panel 2 on the box body of the device, and the housing 1 is specifically fixed relative to the panel 2. This relative fixation includes two methods. One is the method of integrally forming the housing 1 and the panel 2, and the other is the method of separately installing the housing 1 on the panel 2 using fasteners. Consistent with the prior art, an insulator 4 is fixed on the housing 1, and a contact is fixed on the insulator 4. The specific fixation method can be consistent with the prior art, such as injection molding. One end of the contact is a plug connection end for connecting with a matching plug connector 100, and the other end is a component connection end for connecting with the conductive components inside the device box body. For example, the other end of the contact can be welded to the corresponding connection point of the PCB board inside the device box body to achieve electrical conduction.

[0030] In this embodiment, there are two types of contacts in the socket connector, namely the signal contact 6 and the power contact 5. The power contact 5 is used to transmit large currents and is specifically a sheet-like structure with a wide surface, such as a copper bar. The signal contact 6 is used to transmit control signals. That is to say, the socket connector integrates power transmission and signal transmission. However, it should be emphasized that in some other embodiments, the socket connector may only have the power contact 5. It should also be noted that the number of PINs of the power contact 5 can be set as required and will not be specifically limited here.

[0031] Different from the prior art, as Figures 1-3 shown, a bending compensation portion is provided between the plug connection end and the socket connection end of the power contact 5, and the bending compensation portion is configured to be exposed outside the insulator 4.

[0032] When assembling the socket connector, since the bending compensation portion is exposed and can be elastically deformed to a certain extent, in the case where there are installation errors in the conductive components, the deformation of the bending compensation portion of the power contact 5 itself can be utilized to adjust the position of the component connection end to achieve the normal connection between the power contact 5 and the conductive components.

[0033] Specifically, since there may be installation deviations in various directions in the conductive components, as Figure 1 shown, for the convenience of understanding, the mating direction of the socket connector and the plug connector 100 is defined as the front-back direction here, the up-down direction during use is the up-down direction, and the direction perpendicular to the front-back direction and the up-down direction is the left-right direction.

[0034] To enable the power contact 5 to be applicable to the situation where there are errors in the conductive components in different directions, as Figure 4 shown, the bending compensation portion actually includes multiple segments, and the bending directions of different segments are not the same. In terms of the bending direction, the bending compensation portion has bending segments along three different directions of front-back, up-down, and left-right respectively. For the convenience of understanding, first define the plug connection end of the power contact 5 as the power plug connection end 501, and the component connection end of the power contact 5 as the power component connection end 502. There are a total of five bends between the power plug connection end 501 and the power component connection end 502, namely the power first bending segment 503, the power second bending segment 504, the power third bending segment 505, the power fourth bending segment 506, and the power fifth bending segment 507, in order to Figure 3Taking the power contact 5 on the left side as an example, the bending direction of the first power bending section 503 is the up-and-down direction, specifically bending downward; the bending direction of the second power bending section 504 is the left-and-right direction, specifically bending leftward; the bending direction of the third power bending section 505 is the front-and-back direction, specifically bending backward; the bending direction of the fourth power bending section 506 is the up-and-down direction, specifically bending upward; the bending direction of the fifth power bending section 507 is the front-and-back direction, specifically bending backward.

[0035] In the finally formed bending compensation part, the wide surface of the first power bending section 503 is perpendicular to the left-and-right direction, forming a left-and-right compensation section that can swing and deform in the left-and-right direction; the wide surfaces of the second power bending section 504 and the third power bending section 505 are perpendicular to the up-and-down direction, forming an up-and-down compensation section that can swing and deform in the up-and-down direction; the wide surface of the fourth power bending section 506 forms an angle with the front-and-back direction, and the specific value of the angle is not specifically limited. Preferably, it is 90 degrees, that is, the angle is a right angle, that is, perpendicular to the front-and-back direction. However, other values near 90 degrees for the angle can also be used. The fourth power bending section 506 forms a front-and-back compensation section that can swing and deform in the front-and-back direction; the wide surface of the fifth power bending section 507 is perpendicular to the up-and-down direction, forming an up-and-down compensation section that can swing and deform in the up-and-down direction.

[0036] When assembling the socket connector, due to the existence of the above-mentioned front-and-back compensation section, left-and-right compensation section, and up-and-down compensation section, even when there are errors in the conductive components, the elastic deformation of the above-mentioned compensation sections can be utilized to flexibly adjust the position of the connection end 502 of the power component, thereby compensating for the installation errors of the conductive components, ensuring the normal assembly of the socket connector, and at the same time reducing the installation precision requirements for the conductive components.

[0037] As Figure 3 shown, the wide surface of the power plug connection end 501 is perpendicular to the left-and-right direction. Among the above-mentioned compensation sections, the wide surfaces from front to back are perpendicular to the left-and-right direction, perpendicular to the up-and-down direction, form an angle with the front-and-back direction, and perpendicular to the up-and-down direction in sequence, and the wide surface of the power component connection end 502 forms an angle with the front-and-back direction. At this time, actually, there are two sections including the power plug connection end 501 and the left-and-right compensation section that can swing left and right to compensate for errors, two up-and-down compensation sections that can deform up and down, and two sections including the power component connection end 502 and the front-and-back compensation section that can swing back and forth to compensate for errors. The formed bending compensation part is more flexible and has a larger deformation amount.

[0038] Similarly taking Figure 3 as an example, the wide surfaces of the first three compensation sections are perpendicular to the left-and-right direction, perpendicular to the up-and-down direction, and form an angle with the front-and-back direction from front to back. For the setting method where the wide surface of the power plug connection end 501 is perpendicular to the left-and-right direction, such a design is more convenient for bending and can also make the part of the longer power plug connection end 501 exposed outside the insulator 4 flexibly elastically deform.

[0039] Generally speaking, from the above introduction, it can be known that in order to match the installation errors in different directions of the conductive components, the bending compensation part of the power contact 5 should have at least three compensation segments, and at least three compensation segments have different bending directions. The wide surfaces of each compensation segment are respectively perpendicular to the left-right direction, perpendicular to the up-down direction, and form an angle with the front-back direction. On the basis of knowing the above preferred embodiments, those skilled in the art have the ability to flexibly increase or decrease the number of bending segments and the bending directions. For example, in some other embodiments, from front to back, the power contact 5 can also be bent left and right first, then up and down, and then front and back, respectively forming different compensation segments.

[0040] In addition, as Figure 3 shown, the power contacts 5 are arranged in pairs. Preferably, in each pair of power contacts 5, the bending compensation part has a part bent in a direction away from each other, that is, the part bent corresponding to the left-right direction. This can ensure a large insulation distance between the two power contacts 5 and also facilitate the installation of the signal contacts 6.

[0041] On the basis of any of the above embodiments, further preferably, as Figure 1 and Figure 2 shown, the socket connector is further provided with a pre-fixed insulating part 7. The function of the pre-fixed insulating part 7 is to pre-fix each contact to facilitate the overall connection with the conductive component. In this way, on the basis of not affecting the deformation compensation of the elastic bending part for errors, the component connection ends of each contact can be pre-positioned, facilitating the connection with the conductive component.

[0042] Specifically, the component connection end of the contact is press-fitted into the pre-fixed insulating part 7. That is to say, the component connection end of the contact is provided with a forced-fitting structure for press-fitting into the pre-fixed insulating part 7. Preferably, as Figure 3 and Figure 4 shown, the forced-fitting structure adopts a barb structure 9. Correspondingly, the pre-fixed insulating part 7 is provided with a card slot for the release of the barb structure 9. The adoption of the barb structure 9 can ensure the forced-fitting fixation of the contact and the pre-fixed insulating part 7, and at the same time, the cooperation between the card slot and the barb structure 9 can also have a certain positioning effect. Of course, in other embodiments, the forced-fitting structure is not excluded from adopting other forms, such as setting a convex structure on the contact.

[0043] Similarly, for the socket connector integrated with the signal contact 6 and the power contact 5, the signal contact 6 can also be provided with a bending compensation segment between its two ends. For the convenience of understanding, here Figure 4Taking the signal contact 6 shown as an example, the component connection end of the signal contact 6 is defined as the signal component connection end 602, and the plug connection end of the signal contact 6 is defined as the signal plug connection end 601. The bending compensation section between the signal component connection end 602 and the signal plug connection end 601 actually includes 4 bends, namely the signal first bend section 603, the signal second bend section 604, the signal third bend section 605, and the signal fourth bend section 606. Among them, the bending direction of the signal first bend section 603 is the up and down direction. From the perspective in the figure, specifically, it is bent downward. The bending direction of the signal second bend section 604 is the front and back direction, specifically, it is bent backward. The bending direction of the signal third bend section 605 is the up and down direction, specifically, it is bent upward. The bending direction of the signal fourth bend section 606 is the front and back direction, specifically, it is bent backward.

[0044] When assembling the socket connector, the signal first bend section 603, the signal third bend section 605, and the signal component connection end 602 can be deformed in the front and back direction, the signal second bend section 604 and the signal fourth bend section 606 can be deformed in the up and down direction. At the same time, since the overall width and thickness of the signal contact 6 are not too large, the signal contact 6 as a whole can be deformed in the left and right direction. That is to say, at this time, the signal contact 6 can also adapt to "absorb" the installation errors existing in all directions of the conductive component.

[0045] It should be noted that since the signal contact 6 does not require a large current, in fact, the signal contact 6 is a relatively "slender" structure and is relatively flexible itself. Therefore, there is no need to set three bending structures in different directions like the power contact 5.

[0046] In addition, regarding the fixing method of the insulator 4 and the housing 1, taking the solution in which the housing 1 and the panel 2 in the figure are integrated as an example, as Figure 1 and Figure 2 shown, a step 201 can be provided on the back of the panel 2 (the side away from the housing 1), and the insulator 4 is fixed on the step 201, specifically, it can be fixed by bolts 3. Specifically, through holes for the bolts 3 to pass through can be provided on the insulator 4. To facilitate the positioning and installation of the insulator 4, positioning posts 8 can be provided on the step 201, and positioning holes can be provided on the insulator 4. The positioning holes are sleeved outside the positioning posts 8, which can play a preliminary positioning role. At this time, the bolts 3 are tightened to fix the insulator 4. Among them, a boss 202 can be provided on the step 201, and threaded holes can be machined on the boss 202.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still make modifications to the technical solutions described in the foregoing embodiments without creative efforts, or perform equivalent replacements for some of the technical features.
