Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical manufacturing, and in particular relates to a quick-change crimping fixture. Background Art

[0002] Micro connectors are a type of tiny connector that are widely used in electrical equipment.

[0003] The existing crimping fixture structure of micro connectors is mostly as shown in the attached Figure 1 Or the structure disclosed in patent CN110471201B, the patent name is "crimping jig". The existing crimping jigs for micro connectors, including the above patents, have the following shortcomings: First, the crimping jigs for micro connectors mostly include a base and a flip cover, wherein a micro connector is fixedly arranged on the base. Since the probe part in the connector needs to be plugged in and out of the detection connector product, the probe is easily damaged during use and often needs to be repaired or replaced; and the base and the micro connector are an integrated structure, which increases the difficulty of maintenance. In many cases, the base and the connector need to be replaced together, which greatly increases the consumption cost. Secondly, in the existing structure, the product wire or lead connected to the crimping jig is generally inserted into the probe of the WeChat connector, and then crimped to the base through the flap; however, due to the long length of the product wire or lead, different degrees of deformation will occur during the production process, and different degrees of warping will occur after the probe is inserted. Usually, the part where the wire or lead is connected to the probe is stressed due to the compression of the warped part, which in turn causes the probe to deform and be damaged, seriously affecting the service life of the probe; or part of the wire or lead is separated from the probe, resulting in poor contact, affecting the detection connection. Furthermore, since aluminum is easy to process, the base and flap of the crimping jig in the prior art are mostly made of aluminum. At the same time, since aluminum has the disadvantage of being not wear-resistant, and the prior art directly pivots the flap to the base, the pivot part where the flap is pivoted to the base will continuously generate friction and cause wear during use, which in turn causes the flap to not correspond to the base, affecting the poor condition of pressing and stability of use.

[0004] In order to solve the above problems, designing a quick-change crimping fixture is an important technical problem that technicians in this field need to solve. Utility Model Content

[0005] The purpose of the utility model is to solve the above problems existing in the prior art and to provide a quick-change crimping fixture.

[0006] The purpose of the utility model is achieved through the following technical solutions:

[0007] A quick-change crimping jig comprises a base and a flip cover, wherein an integrated circuit is arranged in the base; a probe groove is formed on the base, a probe module is placed in the probe groove and is detachably connected to the probe groove; a probe part and a pressing part are arranged on the probe module, and a pressing block of the pressing part is telescopically arranged above the probe part; the base and the flip cover are pivotally connected by a rotating connecting piece.

[0008] Preferably, the probe portion and the pressing portion are fixed on a probe base, the contour of the probe base is equivalent to the contour of the probe groove, and the probe base is connected to the probe groove by bolts.

[0009] Preferably, a through hole is formed at the bottom of the probe groove, and at least part of the connection terminals in the integrated circuit are located directly below the through hole; the probe part corresponds to the through hole and is electrically connected to the terminals on the integrated circuit.

[0010] Preferably, the pressing part includes a pressing base bolted to the probe base and the pressing block; wherein the pressing base is provided with an opening for accommodating the pressing block; the pressing block and the pressing base are connected by an elastic member, and the setting direction of the elastic member is consistent with the product lead direction.

[0011] Preferably, a receiving groove for accommodating the pressing part is provided on the probe base, and the pressing block is L-shaped, and its inner surface can selectively contact with the probe part; the movement of the pressing block is restricted by the receiving groove.

[0012] Preferably, an opening is formed on a side wall of the probe portion close to the pressing portion, the width of the opening is equivalent to the width of the pressing block, and the two are located on the same axis.

[0013] Preferably, the rotating connector includes a fixed portion detachably connected to the base, and a rotating portion detachably connected to the flip cover; the fixed portion and the rotating portion are pivotally connected, and both are made of stainless steel.

[0014] Preferably, two mutually parallel protrusions are integrally provided on the upper surface of the fixed part, and coaxially arranged pivot holes are formed on the two protrusions; the two rotating parts are located on the outer side of the fixed part, and connecting rods are coaxially arranged on the inner walls thereof, and the connecting rods are inserted into the pivot holes.

[0017] The advantages of the technical solution of the utility model are mainly reflected in:

[0018] The probe module is separated from the base so that the probe module forms a separate structure. If part of the probe is damaged during use, the probe module can be removed from the base for easy repair or replacement, which reduces the repair time and consumption cost.

[0019] The pressing block is slidably arranged on the probe module and flattens the leads on the connector product to ensure the connection stability between the connector and the probe. At the same time, the end leads close to the plug-in are flattened to ensure the warping degree of the leads, improve the crimping accuracy and extend the service life of the connector and the probe.

[0020] The present application sets up the rotating connector independently and is detachably connected to the base and the flip cover respectively. If the rotating connector becomes loose or damaged, only this part can be conveniently disassembled for repair or replacement, thereby reducing the cost of repair and replacement. Furthermore, the present application preferably uses stainless steel material for the rotating connector. Compared with the aluminum material used in the prior art, it has higher hardness and is more wear-resistant, which ensures the accuracy of crimping between the flip cover and the base and can effectively extend the life of the quick-change crimping fixture.

[0025] The purpose, advantages and features of the present invention will be illustrated and explained through the non-limiting description of the following preferred embodiments. These embodiments are only typical examples of the application of the technical solution of the present invention, and any technical solution formed by equivalent replacement or equivalent transformation falls within the scope of protection claimed by the present invention.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. Moreover, in the description of the scheme, with the operator as a reference, the direction close to the operator is the proximal end, and the direction away from the operator is the distal end.

[0027] like Figure 2 As shown, the utility model discloses a quick-change crimping jig, including a base 1 and a flap 2, wherein the base 1 and the flap 2 can be made of aluminum materials disclosed in the prior art, and the outer surfaces of both are coated with an anti-electro-oxidation film; specifically, an anti-electro-oxidation film or coating can be formed on the outer surfaces of the base 1 and the flap 2 by means of anodizing or chemical oxidation, so that the surface hardness of the base 1 and the flap 2 is increased, the corrosion resistance and flame retardancy are improved, etc., and the service life of the quick-release crimping jig is greatly extended.

[0028] like Figures 2 to 3 As shown, an integrated circuit is arranged in the base 1; a probe groove 10 is formed on the base 1. To ensure the stability of the base 1, the present application preferably arranges the probe groove 10 in the center of the base 1. A through hole 100 is opened at the bottom of the probe groove 10, and at least part of the connection terminals in the integrated circuit are located directly below the through hole 100.

[0029] The probe module 3 is placed in the probe groove 10 and is detachably connected to the probe groove 10. Specifically, the probe module 3 is provided with a probe portion 31 and a pressing portion 32, both of which are fixed on a probe base 33. The contour of the probe base 33 is equivalent to the contour of the probe groove 10, and the probe base 33 is connected to the probe groove 10 by bolts. Furthermore, the probe portion 31 corresponds to the through hole 100 and is electrically connected to the terminal on the integrated circuit. The probe module and the base are separated so that the probe module forms a separate structure. If part of the probe is damaged during use, the probe module can be removed from the base, which is convenient for maintenance or replacement, reducing maintenance time and consumption costs.

[0030] like Figure 3As shown, the probe base 33 is provided with a receiving groove 330 for accommodating the pressing part 32, that is, a protrusion matching the receiving groove 330 is formed at the bottom of the pressing base 321, and the two ends of the protrusion are connected to the probe base 33 by bolts. The pressing part 32 includes a pressing base 321 and a pressing block 322 which are bolted to the probe base 33. The pressing base 321 is provided with an opening for accommodating the pressing block 322. The pressing block 322 is connected to the pressing base 321 by an elastic member, and the setting direction of the elastic member is consistent with the product lead direction; that is, the pressing block 322 of the pressing part 32 can be telescopically arranged above the probe part 31. The elastic member includes but is not limited to the spring disclosed in the prior art, and can be replaced by a component with elastic function including a spring, which is not limited here.

[0031] Further, such as Figure 2 or Figure 3 As shown, in the present application, the pressing block 322 is preferably designed to be L-shaped, and its inner surface can be selectively in contact with the probe part 31; and the pressing block 322 is restricted in movement by the accommodating groove 330. Furthermore, in order to facilitate the unresistance movement of the pressing block 322, an opening 310 is formed on the side wall of the probe part 31 close to the pressing part 32, and the width of the opening 310 is equivalent to the width of the pressing block 322, and the two are located on the same axis. It can be seen that when it is necessary to plug the detection connector product with the probe part 31, the pressing block 322 will overcome the force of the elastic member under the action of external force and move toward the pressing base 321, and after the plugging is completed, it is driven by the elastic member to move toward the probe part, and the leads on the connector product are flattened to ensure the connection stability between the connector and the probe, and at the same time, the end leads of all leads close to the plugging are flattened to ensure the warping of the leads, improve the crimping accuracy and extend the service life of the connector and the probe.

[0032] like Figure 3 to Figure 4 As shown, the base 1 and the flap 2 are pivotally connected via a rotating connector 4. The rotating connector 4 includes a fixed portion 41 detachably connected to the base 1, and a rotating portion 42 detachably connected to the flap 2. Compared with the prior art in which the pivot portion is integrally arranged with the base and / or the flap, the present application independently arranges the rotating connector and detachably connects it to the base and the flap, respectively. If the rotating connector becomes loose or damaged, only the part can be conveniently disassembled for repair or replacement, thereby reducing the cost of repair and replacement. In addition, in the present application, the rotating connector is preferably made of stainless steel material, which is harder and more wear-resistant than the aluminum material used in the prior art, thereby ensuring the accuracy of crimping between the flap and the base, and effectively extending the life of the quick-change crimping jig.

[0033] The fixing portion 41 is pivotally connected to the rotating portion 42. Figure 3 As shown, two mutually parallel protrusions 411 are integrally provided on the upper surface of the fixing portion 41, and coaxially arranged pivot holes 410 are formed on the two protrusions 411; the two rotating portions 42 are located on the outer side of the fixing portion 41, and connecting rods are coaxially arranged on the inner walls thereof, and the connecting rods are inserted into the pivot holes 410.

[0034] In order to further improve the crimping stability between the flip cover 2 and the base 1, the present application provides a lock 5 for locking the flip cover 2 at one end of the base 1 away from the flip cover 2. The lock 5 is connected to the base 1 through the connecting block 15, and the connecting block 15 is connected to the base 1 through bolts and is pivotally connected to the lock 5. Since the base 1 is made of aluminum, which has low hardness and is not wear-resistant, a connecting block 15 is provided between the lock 5 and the base 1. The connecting block 15 can be made of hard plastic or other materials with higher hardness disclosed in the prior art, which are not limited here, effectively reducing the wear of the base and extending its service life, while facilitating the replacement and maintenance of the lock part.

[0035] There are many implementation methods of the utility model, and all technical solutions formed by equivalent transformation or equivalent transformation fall within the protection scope of the utility model.
