Description

Technical Field

[0001] This invention belongs to the field of cable crimping technology, specifically relating to a crimping tool that can move and position the contact element. Background Technology

[0002] Outdoor photovoltaic (PV) equipment installations typically require the use of crimping tools to connect connector contacts to cables using a cold-pressing method. Commonly used crimping tools include wire crimping pliers. During the crimping process, the operator usually needs to hold the contact with one hand and the cable with the other, fixing their positions before using the crimping pliers to perform the crimping. Without a fixing device, the crimping pliers cannot be operated by a single person, and vibrations during operation often cause the cable to move relative to the contact, resulting in unstable crimping quality.

[0003] In addition, in scenarios where the compression ratio of the contact component is large, or where the metal extrusion and flow are intense during the crimping process, the contact component body will undergo large deformation and movement relative to the crimping jaws. If this is not constrained, it will also lead to poor shape consistency in the crimping and unstable crimping quality.

[0004] Figure 1 , 2 The principle of contact deformation and displacement during the crimping of cables using conventional wire crimping pliers is explained. The contact shown by the dashed line is the original contact 101 before crimping, and the contact shown by the solid line is the crimped contact 102 after crimping. Figure 1 , 2 As can be seen, when the crimping pliers crimp the contacts and cables, the contacts are metal parts. Due to the deformation and flow during the metal crimping process, a circumferentially concave crimping area 103 is formed in the middle of the rear section of the original contact 101. This results in a radial displacement Δa between the axis L1 of the original contact 101 and the axis L2 of the crimped contact 102 relative to the lower jaw 1 of the crimping pliers. The middle of the original contact 101 is squeezed to form the crimping area 103. The axial flow of the metal material causes the two ends of the crimped contact 102 to also have axial displacements Δb and Δc respectively compared to the two ends of the original contact 101.

[0005] Therefore, when using crimping pliers to crimp contacts and cables, the positioner used needs to take into account the aforementioned changes in the contacts.

[0006] The positioning devices used in existing photovoltaic pressing structures generally include the following three forms:

[0007] (1) Cable + terminal positioning type: As shown in patent CN112969555A, the product positions the contact through the anvil on the lower jaw and positions the cable through a movable bracket;

[0008] (2) Rotation adjustment type: As shown in patent CN216504823U, the positioner is provided with positioning holes for multiple specifications of contact parts. The rotation center of the positioner is eccentrically installed with the jaws. By rotating the positioner, the positioning holes of different specifications of contact parts can be aligned to achieve positioning of different specifications of contact parts.

[0009] (3) Threaded translational adjustment type: As shown in patent CN212114253U, a stud is provided on the positioner, and the assembly depth of the contact part in the positioner can be adjusted by the stud, so as to realize the positioning of contact parts of different specifications.

[0010] In the three types of positioning devices mentioned above, the jaws and the contact body or cable positioning part cannot move relative to each other, making it unable to cope with scenarios where metal extrusion and flow are relatively intense during the crimping process (such as...). Figure 1 , 2 As shown in the figure, when the displacements Δa, Δb, and Δc of the contact parts are large, they cannot adapt accordingly, resulting in obstructed displacement of the contact parts during the crimping process. Consequently, product deformation cannot be controlled, and crimping consistency is difficult to guarantee. Summary of the Invention

[0011] The purpose of this invention is to provide a crimping clamp that can follow and position the contact parts. The deformation and displacement of the contact parts during the crimping process are compensated by multiple moving parts inside the positioner, thereby realizing the follow and positioning of the contact parts during the product crimping process and improving the reliability and quality consistency of the product crimping.

[0012] To achieve the above objectives, the technical solution adopted by the present invention is: a wire clamping tool capable of moving and positioning contact parts, comprising a wire clamping tool body and a positioner, wherein the wire clamping tool body includes an upper jaw and a lower jaw arranged opposite to each other, and the positioner is fixedly connected to the lower jaw; the positioner includes:

[0013] A positioner base, wherein a radial movement compensation component for the contact element is provided inside the positioner base, and the radial movement compensation component for the contact element is slidably disposed on the positioner base in the radial direction;

[0014] The axial movement compensation component for the contact element is slidably connected to the radial movement compensation component for the contact element along the axial direction. The axial movement compensation component for the contact element is provided with a positioning hole for mounting the contact element, and an axial positioning surface for the contact element is provided in the positioning hole for engaging with the flange on the contact element to stop and position the contact element axially.

[0015] An axial motion elastic element is provided in the sliding direction of the contact axial motion compensation element, which is used to push the contact axial motion compensation element to reset in the axial direction.

[0016] A radial motion elastic element is also provided between the radial motion compensation element of the contact element and the positioner base, which is used to push the radial motion compensation element of the contact element to reset radially.

[0017] Its beneficial effects are as follows: When the upper and lower jaws close the mold and crimp the contact and cable, the metal material flows axially after the contact is squeezed, causing axial displacement at both ends of the contact. After the mold closes, the overall axis of the contact undergoes radial displacement. At this time, when the front end of the contact moves axially, an axial force is applied to the axial motion compensation component of the contact through the cooperation between the flange and the positioning surface of the contact. This causes the axial motion compensation component to slide axially along the radial motion compensation component of the contact, following the axial displacement of the front end of the contact. When the contact moves radially as a whole due to the downward pressure of the upper jaws, the radial force is transmitted to the radial motion compensation component of the contact through the axial motion compensation component, causing the radial motion compensation component to follow the radial displacement of the contact. This achieves the follow-up positioning of the contact in the axial and radial directions, ensuring the regularity of the structure after crimping and improving the reliability and quality consistency of the product during crimping.

[0018] The radial and axial elastic elements can release the elastic potential energy generated by compression after the pressing is completed, thereby pushing the axial and radial motion compensation elements of the contact element to reset.

[0019] Furthermore, the radial motion compensation component of the contact element includes a guide shaft that passes through a through hole at the bottom of the locator base and slides in cooperation with the through hole.

[0020] Its beneficial effect is that the guide shaft and the through hole form a shaft-hole mating structure, which can provide guidance for the radial movement of the contact component and the radial movement of the compensation component.

[0021] Furthermore, the portion of the guide shaft that extends out of the locator base is provided with a locating pin.

[0022] Its beneficial effect is that the setting of the locating pin can prevent the radial movement compensation component of the contact part from dislodging from the locator base.

[0023] Furthermore, the radial motion elastic element is sleeved on the guide shaft.

[0024] Its beneficial effect is that the nesting method can ensure smoother radial movement of the contact component and avoid jamming.

[0025] Furthermore, the radial motion elastic element is a spring or an elastic sleeve.

[0026] Its beneficial effect is that it limits the structural form of the radial motion elastic element, making it easier to implement selectively.

[0027] Furthermore, the radial motion compensation component of the contact element also includes a boss connected to the upper end of the guide shaft, and the lower end of the axial motion compensation component of the contact element is provided with a groove, which slides in cooperation with the boss through the groove.

[0028] Its beneficial effects are: it defines the sliding structure of the boss and the groove, and provides the setting method of the boss and the groove.

[0029] Furthermore, the boss is provided with ribs on opposite sides, and the groove is provided with grooves on opposite sides that can accommodate the ribs.

[0030] Its beneficial effects are: the cooperation between the rib and the groove can not only achieve sliding connection, but also constrain each other in the radial direction, preventing the axial movement compensation component of the contact component from detaching from the radial movement compensation component of the contact component in the radial direction.

[0031] Furthermore, the radial motion compensation component of the contact element also includes a connecting plate connected to the upper end of the guide shaft. The surface of the connecting plate is provided with a groove, and the lower end of the axial motion compensation component of the contact element is provided with a protrusion that can slide and cooperate with the groove.

[0032] Its beneficial effects are: it defines the sliding structure of the protrusion and the groove, and provides the setting method of the protrusion and the groove.

[0033] Furthermore, the positioner also includes a positioner housing, which is fastened to the positioner base and forms a mounting cavity with the positioner base to accommodate the radial movement compensation component and the axial movement compensation component of the contact element.

[0034] Its beneficial effect is that the positioning housing can prevent the radial movement compensation component and the axial movement compensation component of the contact element from being exposed.

[0035] Furthermore, the axial movement elastic element is a spring sheet structure. The fixing part of the spring sheet structure is fixed between the positioner base and the positioner housing. The elastic part of the spring sheet structure extends obliquely into the positioner base and abuts against the end face of the axial movement compensation element of the contact element.

[0036] Its beneficial effects are: a structural form and installation method for limiting axial movement of elastic elements.

[0037] Furthermore, the axial movement elastic element is a spring, with its two ends pressing against the end face of the axial movement compensation element of the contact element and the inner wall of the locator housing, respectively.

[0038] Its beneficial effects are: another structural form and installation method for limiting axial movement elastic elements.

[0039] Furthermore, the mating surfaces of the lower jaw and the upper jaw are pressing surfaces, and the pressing surface of the lower jaw is provided with a contact positioning anvil for cooperating with the upper jaw to press the contact element.

[0040] Its beneficial effect is that the contact positioning anvil can be used for positioning the rear section of the contact.

[0041] Furthermore, the lower jaw and the upper jaw are slidably engaged by a positioning post and a positioning hole, which are disposed on the corresponding pressing surfaces.

[0042] Its beneficial effect is to ensure the reliability and stability of the relative movement of the upper and lower jaws.

[0043] The beneficial effects of this invention are: by compensating for the deformation and displacement of the contact parts during the pressing process through multiple moving parts inside the positioner, this invention achieves the follow-up positioning of the contact parts during the product pressing process, thereby improving the reliability and quality consistency of the product pressing process.

[0053] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, but this should not be construed as limiting the invention in any way.

[0054] See attached document Figure 3 , 4 As shown, a wire clamping tool capable of positioning contact components includes a wire clamping tool body 4 and a positioner 3. The wire clamping tool body 4 is provided with a lower jaw 1 and an upper jaw 2 that can be opened and closed. The lower jaw 1 and the upper jaw 2 can move relatively linearly under the action of clamping force, thereby crimping the contact component and the cable located between the lower jaw 1 and the upper jaw 2 together.

[0055] The lower jaw 1 and upper jaw 2 are semicircular structures with the same radius, and their opposing mating surfaces are pressing surfaces. In other embodiments, the lower jaw 1 and upper jaw 2 can also be other shapes, as long as they have opposing pressing surfaces.

[0056] like Figure 5 As shown, in this embodiment, a contact positioning anvil 21 for the extrusion contact 100 is provided on the pressing surfaces of the lower jaw 1 and the upper jaw 2. The contact positioning anvil 21 protrudes from the pressing surface and has an extrusion groove. A positioning post 22 is provided on each side of the contact positioning anvil 21 of the lower jaw 1. The pressing surface of the upper jaw 2 has a positioning hole that slides with the positioning post 22. The sliding fit between the positioning post 22 and the positioning hole provides guidance for the mold closing of the lower jaw 1 and the upper jaw 2. Alternatively, in other embodiments, the positions of the positioning post 22 and the positioning hole can be interchanged. Two first screw mounting holes 5 are provided on one axial end face of the lower jaw 1 for connecting the positioner 3.

[0057] like Figure 5 As shown, the positioner 3 includes a positioner base 7, an axial movement elastic element 9, a positioner housing 13, a radial movement elastic element 14, a contact radial movement compensation element 15, a contact axial movement compensation element 18, and a positioning pin 20.

[0058] The positioner base 7 has an axially extending through groove in its middle. Two second screw mounting holes 6 are located at the front end of the positioner base 7, on either side of the through groove. Two third screw mounting holes 8 are located at the rear end of the positioner base 7, below the through groove.

[0059] like Figure 5 As shown, the locator housing 13 has two fourth screw mounting holes 10 at its rear end and two fifth screw mounting holes 12 at its front end. The locator housing 13 is fastened to the locator base 7, and cooperates with the through groove to form a mounting cavity for accommodating the radial movement elastic member 14, the radial movement compensation member 15, and the axial movement compensation member 18. A screw 11 is used to pass through the fifth screw mounting holes 12 and the third screw mounting holes 8 to achieve a fixed connection between the front end of the locator base 7 and the front end of the locator housing 13. After the screw 11 passes through the fourth screw mounting holes 10 of the locator housing 13 and the second screw mounting holes 6 of the locator base 7 in sequence, it is then connected to the first screw mounting hole 5, connecting the rear end of the locator housing 13 and the rear end of the locator base 7 together and fixing them to the end face of the lower jaw 1. In this invention, the descriptions of "front" and "rear" refer to the placement direction of the contact member 100 during pressing; the direction shown by the front section 104 of the contact member is "front," and the direction shown by the rear section 105 of the contact member is "rear." Furthermore, in Figure 5 The diagram provides a directional legend for reference.

[0060] In this embodiment, the axial motion elastic element 9 is a bent spring sheet structure, with one end being a fixed part and the other end being an elastic part. The fixed part has two through holes for alignment with the third screw mounting hole 8 and the fifth screw mounting hole 12. When the screw 11 connects the front end of the locator base 7 to the front end of the locator housing 13, it clamps and fixes the fixed part of the axial motion elastic element 9 between the two, and the elastic part of the axial motion elastic element 9 extends backward into the through groove of the locator base 7, pressing against the front end of the contact axial motion compensation element 18, that is, against the sliding direction of the contact axial motion compensation element 18. During the pressing process, after the contact axial motion compensation element 18 moves forward along the axial direction, the axial motion elastic element 9 is compressed and deformed, storing elastic potential energy for the axial reset of the contact axial motion compensation element 18 after pressing.

[0061] In other embodiments, a spring can be used instead of the spring sheet structure of this embodiment as the axial movement elastic element 9. In this case, the two ends of the spring are respectively pressed against the front end of the contact axial movement compensation element 18 and the inner wall of the locator housing 13.

[0062] The axial movement compensation component 18 of the contact element is provided with a contact element positioning hole 19 for accommodating the front section 104 of the contact element. The contact element positioning hole 19 is provided with an axial positioning surface 23 for engaging with a stop flange 106 on the side of the front section 104 of the contact element to axially position the contact element 100. Figure 7 As shown.

[0063] The contact axial movement compensation component 18 is slidably disposed at the upper end of the contact radial movement compensation component 15. Specifically, the upper end of the contact radial movement compensation component 15 is provided with a boss 1501, and raised ribs 16 are provided on opposite sides of the boss 1501; the lower end face of the contact axial movement compensation component 18 is provided with a groove to accommodate the boss 1501, and the two opposite inner walls of the groove are provided with sliding grooves 17 that slide in cooperation with the raised ribs 16. During the crimping process of the caliper on the contact 100 and the cable 200, when the front section 104 of the contact experiences axial displacement, the contact axial movement compensation component 18 can slide axially relative to the contact radial movement compensation component 15 through the cooperation of the raised ribs 16 and the sliding grooves 17, and squeeze the axial movement elastic component 9. After the crimping is completed, the axial movement elastic component 9 releases its elastic force to push the contact axial movement compensation component 18 back to its axial position. Therefore, the axial movement elastic element 9 can also ensure that the axial movement compensation element 18 of the contact element is always slidably connected with the radial movement compensation element 15 of the contact element, and will not disengage.

[0064] In other embodiments, the positions of the boss 1501 and the groove can be interchanged. For example, the upper end of the radial motion compensation member 15 of the contact member is provided with a connecting plate, the surface of the connecting plate is provided with a groove, and the lower end of the axial motion compensation member 18 of the contact member is provided with a boss or protrusion that can slide with the groove.

[0065] A guide shaft 1502 is provided at the lower part of the boss 1501 of the radial motion compensation component 15 of the contact element. The guide shaft 1502 extends downward through the through hole of the locator base 7, forming a hole-shaft sliding fit. A locating pin 20 is installed on the part of the guide shaft 1502 that extends out of the locator base 7. A spring is also sleeved on the guide shaft 1502. The upper end of the spring abuts against the lower end face of the boss 1501, and the lower end of the spring abuts against the bottom of the through groove of the locator base 7. The spring is compressed and deformed by radial extrusion force during the crimping of the contact element and the cable by the crimping pliers. After the crimping is completed, the spring releases its elastic force to push the radial motion compensation component 15 of the contact element to move radially back to its original position. In this process, the spring acts as the radial motion elastic element 14, providing elastic force for the return of the radial motion compensation component 15 of the contact element. The locating pin 20 can prevent the radial motion compensation component 15 of the contact element from detaching from the locator base 7 during the return process. In other embodiments, a rubber sleeve or the like can be used instead of the spring as the radial motion elastic element 14.

[0066] The following is combined Figure 6 , Figure 7 The crimping process of the present invention will be described.

[0067] Figure 7 (a) shows the initial moment of crimping of contact 100 and cable 200. At this time, the upper jaw 2 and lower jaw 1 of the crimping pliers are not closed. The contact axial movement compensation component 18 and the contact radial movement compensation component 15 of the positioner 3, as well as all other components, are in the initial state. Contact 100 is installed in the contact positioning hole 19 of the contact axial movement compensation component 18, and the contact axial positioning surface 23 in the contact positioning hole 19 cooperates with the flange 106 of the contact front section 104 to ensure the precise positioning of contact 100 relative to the crimping jaws. There is a certain gap between the contact rear section 105 and the contact positioning anvil 21. The head core of cable 200 is inserted into the crimping cylinder of the contact rear section 105.

[0068] When installing the contact 100, the front section 104 of the contact is installed inside the contact positioning hole 19, and the rear section 105 of the contact is exposed outside the contact positioning hole 19. The contact 100 is a hollow tubular structure, and the exposed rear section 105 of the contact is used for crimping with the end of the cable 200.

[0069] Figure 7(b) shows the moment of crimping. At this time, the distance between the upper jaw 2 and the lower jaw 1 of the crimping clamp is the smallest. The rear section 105 of the contact is squeezed and deformed by the clamping force of the upper jaw 2 and the lower jaw 1, and the metal material of the contact 100 flows axially, resulting in an axial displacement Δb of the front section 104 of the contact and an axial displacement Δc of the rear section 105 of the contact. Since the contact 100 is installed in the contact positioning hole 19 of the contact axial movement compensation component 18, when the front section 104 of the contact is axially displaced, the flange 106 on the front section 104 of the contact will act on the axial positioning surface 23 of the contact, thereby applying an axial thrust to the axial movement compensation component 18 of the contact. After the contact axial movement compensation component 18 is subjected to force, it moves axially relative to the radial movement compensation component 15 of the contact. At this time, the axial movement elastic component 9 set between the locator base 7 and the axial movement compensation component 18 of the contact is compressed, and the work done by the thrust is stored in the form of elastic potential energy. The displacement Δc of the rear section 105 of the contact element is not restricted because the tail of the cable 200 is not properly positioned.

[0070] at the same time, Figure 7 In (b), the contact 100 is compressed by the upper jaw 2, and the overall axis of the contact 100 moves downward by Δa, that is, the radial displacement is Δa. At this time, the contact 100 transmits the radial displacement to the contact radial displacement compensation component 15 through the contact axial motion compensation component 18. Subsequently, the contact radial displacement compensation component 15 is driven to move radially relative to the locator base 7 along the hole shaft mating axis. During this process, the radial motion elastic component 14 between the locator base 7 and the contact radial displacement compensation component 15 is compressed, and the work done by the thrust is stored in the form of elastic potential energy.

[0071] like Figure 7 (c) shows the moment when crimping is completed. At this time, the upper jaw 2 of the crimping pliers moves upward, and the elastic potential energy stored in the two elastic elements in the positioner 3 is released, pushing the contact 100 out of the contact positioning anvil 21 in the lower jaw 1. At this time, the crimped contact 100 can be removed from the positioner to enter the next crimping cycle.

[0072] In this invention, "axial" and "radial" are defined with reference to the contact member 100, which is a hollow tubular structure. The direction parallel to the axis of the contact member is "axial", and the direction perpendicular to the axis of the contact member is "radial".

[0073] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Those skilled in the art should understand that modifications or equivalent substitutions can be made to the specific implementation of the present invention with reference to the above embodiments. Any modifications or equivalent substitutions that do not depart from the spirit and scope of the present invention are within the protection scope of the pending claims.
