[0040] The following refers to Figures 1 to 5 Describe a force measuring device for removing a connector contact according to some embodiments of the present application.

[0041] Refer to Figures 1 to 5 As shown, an embodiment of the present application provides a force measuring device for removing a connector contact, including: a body 1, an ejecting member 2, and an elastic member 3; wherein, the body 1 forms a first accommodating portion; the ejecting member 2 is disposed in the first accommodating portion, and the ejecting member 2 can move in the first accommodating portion to at least partially extend out of the first accommodating portion, and a scale 23 is formed on at least the part of the ejecting member 2 that extends out of the first accommodating portion; the elastic member 3 is connected to the ejecting member 2 and moves along with the movement of the ejecting member 2.

[0042] As Figures 1 to 3 shown, the principle of performing the force measuring function is as follows: The right end of the ejecting member 2 exposes the body 1, and a scale 23 is provided on this exposed part. When the rightmost end of the ejecting member 2 is axially pressed against the contact to push the contact out of the insulator, the ejecting member 2 moves to the left and compresses the elastic member 3. The length of the contraction of the elastic member 3 can be read according to the scale 23 on the ejecting member 2. According to the contraction length and elastic coefficient of the elastic member 3, the magnitude of the contact holding force can be determined, thereby realizing the force measuring function. When the ejecting member 2 is used to install the contact, that is, to push the contact into the insulator, taking the holding force measured in the above force measuring step as the standard, if the holding force measured during the assembly of the contact meets the above standard requirements, it can be determined that the contact is inserted in place.

[0043] In an embodiment of the present application, preferably, as Figures 1 to 5 shown, the body 1 includes a housing 11, an auxiliary measuring member 4, and an auxiliary removing member 5; wherein, the housing 11 is formed with a first accommodating portion, and the first accommodating portion is a first installation cavity penetrating through opposite ends of the housing. The ejecting member 2 is disposed in the first installation cavity, and the ejecting member 2 can move along the length direction of the first installation cavity;

[0044] The elastic member 3 is also disposed in the first installation cavity and extends along the first installation cavity. The elastic member 3 is connected to the ejecting member 2 and can move synchronously with the ejecting member 2;

[0045] The auxiliary measuring member 4 is sleeved outside the housing 11 and extends to the front of the housing 11, and the auxiliary measuring member 4 is movably connected to the housing 11 along the length direction of the ejecting member 2; the ejecting member 2 can extend out of the front end portion of the auxiliary measuring member 4, and a part of the ejecting member 2 extending out of the front end portion of the auxiliary measuring member 4 is provided with a scale 23 for realizing the operation of measuring force;

[0046] The auxiliary removing member 5 is detachably disposed between the auxiliary measuring member 4 and the limiting portion 111 of the housing 11 along the length direction of the ejecting member 2. In a state where the auxiliary removing member 5 is disposed between the auxiliary measuring member 4 and the limiting portion 111 of the housing 11 along the length direction of the ejecting member 2, the ejecting member 2 is received in the front end portion of the auxiliary removing member 5 for realizing the operation of removing the contact body.

[0047] The working principle of the force measuring device for removing the connector contact body is as follows:

[0048] As Figures 1 to 3 shown, the principle of performing the force measuring function is as follows: Assemble the auxiliary measuring member 4 and the housing 11 together, and then move the auxiliary measuring member 4 to the leftmost side, and the right end of the ejecting member 2 is exposed. A scale 23 is provided on this exposed part. When axially pressing the contact body with the rightmost end of the ejecting member 2, that is, pushing the contact body out of the insulator, the ejecting member 2 moves to the left and compresses the elastic member 3. The contracted length of the elastic member 3 can be read according to the scale 23 on the ejecting member 2. According to the contracted length and elastic coefficient of the elastic member 3, the magnitude of the contact body holding force can be determined, so as to realize the force measuring function. When installing the contact body with the ejecting member 2, that is, pushing the contact body into the insulator, taking the holding force measured in the above force measuring step as the standard, if the holding force measured during the assembly of the contact body meets the above standard requirements, it can be determined that the contact body is inserted in place.

[0049] As Figure 4 and Figure 5As shown in the figure, the principle of implementing the contact body extraction function is as follows: Assemble the auxiliary extraction member 5, the auxiliary measurement member 4, and the housing 11 together. It can be seen that due to the addition of the auxiliary extraction member 5, that is, along the length direction of the ejection member 2, the auxiliary measurement member 4 is shifted outward to the right, so that the ejection member 2 is received inside the auxiliary measurement member 4. At this time, a part of the structure of the auxiliary measurement member 4 extending to the front end of the housing 11 can be used to extend into the insulator hole cavity, and this part of the structure is used to tighten the contact body claw, that is, one end of the claw is received into the front end of the auxiliary measurement member 4, resulting in the outward expansion of the remaining part and the separation from the contact body. At this time, the contact body loses the axial positioning function of the claw inside the insulator, and then the contact body can be ejected by the ejection member 2 (note that this device is not only applicable to the contact body structure positioned by the claw, but can be realized for all contact body positioning structures).

[0050] Combined with the above working principle, it can be seen that this device solves the problem of the single structural function of the existing contact body extraction device, that is, while this device satisfies the extraction of the contact body, it can also judge whether the contact body is properly inserted during reinstallation by measuring the magnitude of the axial holding force value after the contact body is inserted, so as to avoid the problem of needle withdrawal caused by improper operation.

[0051] In an embodiment of the present application, preferably, as Figure 1 、 Figure 2 and Figure 4 shown, the structure of the auxiliary measurement member 4 and the housing 11 movingly connected along the length direction of the ejection member 2 can be described in detail as follows: The force measuring device for the extraction of the connector contact body further includes a first limiting member 6, a second limiting member 7, and an elastic clamping member 8; wherein, the housing 11 is formed with a first limiting groove 131 extending along its length direction, and the depth of the first limiting groove 131 gradually decreases along the ejection direction of the ejection member 2;

[0052] A part of the structure of the first limiting member 6 is embedded at one end of the auxiliary measurement member 4 close to the elastic member 3, and another part of the structure of the first limiting member 6 is arranged in the first limiting groove 131 and can slide along the first limiting groove 131;

[0053] The structure of the auxiliary measurement member 4 along its length direction and in front of the first limiting member 6 is formed with a second limiting groove 43, and the depth of the second limiting groove 43 gradually decreases along the ejection direction of the ejection member 2; A part of the structure of the second limiting member 7 is embedded at one end of the housing 11 away from the elastic member 3, and another part of the structure of the second limiting member 7 is arranged in the second limiting groove 43 and can slide along the second limiting groove 43;

[0054] An elastic clamping member 8 is provided between the second limiting member 7 and the housing 11, and the second limiting member 7 can apply a force to the elastic clamping member 8 along a direction perpendicular to the ejection direction of the ejection member 2. Preferably, the elastic clamping member 8 is a circlip 9.

[0055] In this embodiment, the left and right movement and stopping operations of the auxiliary measuring member 4 are realized by using the first limiting member 6, the second limiting member 7, the elastic clamping member 8 and the two limiting grooves, as follows:

[0056] When the auxiliary measuring member 4 moves to the left, the inclined surface inside it will gradually press the second limiting member 7, and the second limiting member 7 will further compress the elastic clamping member 8. When the auxiliary measuring member 4 moves to the leftmost position, the compression amount of the elastic clamping member 8 reaches the maximum. At this time, the elastic clamping member 8 will give the auxiliary measuring member 4 a maximum reverse acting force through the second limiting member 7, so as to achieve the purpose of restricting the movement of the auxiliary measuring member 4. At this time, without external force, the auxiliary measuring member 4 is fixed axially, and then the force measuring function of the device can be realized. When the function of taking out the contact body needs to be realized, an external force can be applied to force the auxiliary measuring member 4 to move to the rightmost position, and at this time, the auxiliary taking-out member 5 is clamped between the auxiliary measuring member 4 and the limiting part 111 of the housing 11 to limit the auxiliary measuring member 4.

[0057] Of course, it is not limited to the above structure. For the structure in which the auxiliary measuring member 4 and the housing 11 are movably connected along the length direction of the ejection member 2, the following structure can also be adopted, that is, the auxiliary taking-out member 5 and the housing 11 are connected by threads, and the movable connection between the two can also be realized, but there is no stopping device during the rightward movement of the auxiliary measuring member 4, and there is no difference in other aspects.

[0058] In an embodiment of the present application, preferably, as Figure 5 shown, the auxiliary taking-out member 5 is a snap ring structure with an opening, which is convenient for the installation and disassembly of the housing 11.

[0059] In an embodiment of the present application, preferably, as Figure 1 and Figure 4 shown, the body 1 further includes a nut 12 and a sleeve 13; wherein, along the length direction of the ejection member 2, the sleeve 13 extends into the first installation cavity and abuts against the limiting table inside the housing 11; the housing 11 is formed with a first channel penetrating through its opposite ends, and the sleeve 13 is formed with a second channel penetrating through its opposite ends, and the second channel is connected in sequence with the first channel to form the first installation cavity;

[0060] The nut 12 is sleeved on one end of the outer shell 11 and the outside of the sleeve 13 for connecting the sleeve 13 and the outer shell 11 into an integral body. Specifically, the nut 12 is threadedly connected to the outer shell 11, and the end cover portion of the nut 12 just abuts against the limiting table portion of the sleeve 13, thus playing a role in limiting the sleeve 13; the auxiliary measuring member 4 is sleeved on the outside of the sleeve 13;

[0061] The auxiliary extraction member 5 is detachably sleeved on the outside of the sleeve 13 and is located between the auxiliary measuring member 4 and the nut 12.

[0062] Furthermore, preferably, as Figure 1 shown, the force measuring device for connector contact extraction further includes an operation cap 14. The operation cap 14 is sleeved on the end of the ejector member 2 that extends out of the outer shell 11 and is far from the auxiliary extraction member 5. The operation cap 14 is sleeved on the outer shell 11 and can specifically adopt a threaded connection, which is convenient for installation and disassembly. The operation cap 14 can be selected as a ball cap, which is convenient for holding by hand and convenient for operation.

[0063] Furthermore, preferably, as Figure 1 shown, the force measuring device for connector contact extraction further includes a circlip 9. One end of the elastic member 3 is connected to the ejector member 2 through the circlip 9, playing a role in connecting the ejector member 2 and the elastic member 3.

[0064] In this embodiment, based on the above structure, the assembly process of the device is as follows: The operation cap 14 and the ejector member 2 are threadedly connected. An elastic member 3 is installed between the outer shell 11 and the ejector member 2. The elastic member 3 is connected to the ejector member 2 through a gasket 10 and a circlip 9 to achieve anti-disengagement. After the second limiting member 7 and the circlip 9 are installed on the sleeve 13, the nut 12 and the outer shell 11 are threadedly connected. The nut 12, the outer shell 11 and the circlip 9 jointly achieve the axial positioning of the sleeve 13. Finally, the auxiliary measuring member 4, the first limiting fastener, the second limiting member 7 and the elastic clamping member 8 are assembled, and it is judged whether to install the auxiliary extraction member 5 according to actual needs.

[0065] It can be seen that the above assembly process is simple and convenient, and each component cooperates firmly with each other, and the overall structure is stable.
