Abstract
Description
Technical Field
[0001] The invention belongs to the field of electrical contact connection, and in particular relates to a wool button contact piece with different filling rates. Background Art
[0002] A button contact is a contact component used in electronic connectors. Its main function is to provide electrical connection while ensuring good contact and reducing electrical impedance. It is usually used in connection scenarios that require high reliability. In order to adapt to high-reliability connection scenarios and the vertical interconnection and transmission function of signals that the button contact itself needs to have, the button contact is required to have a certain degree of elasticity and be able to make reliable contact after installation.
[0003] Because the fur button contact is formed by random winding and has a more elastic property, there is a possibility that the fur button contact will be permanently deformed when it is exposed to external force, which makes it difficult to install and protect the fur button. In order to meet the above requirements, traditional fur button contacts generally adopt the method of adding protection mechanisms and installation mechanisms on the outside of the fur button contact to solve the above problems.
[0004] For example, CN202111264751.0 discloses an adaptively installed button contact, in which a fat point is set in the middle of the button contact, and the fat point is elastically interference fit with the mounting structure during assembly, which solves the problem of fixing the button itself and improves its own mechanical stability and signal transmission reliability. CN201811451894.0 discloses a button connector, which fixes the button through an installation structure composed of a fixing ring, a positioning groove, etc., solving the problem that the structure of the button connector in the prior art is not suitable for large-scale production.
[0005] CN201720607346.7 discloses a wire pin, which has a relatively hard and smooth end by setting a welding part at the end of the metal wire, which is easy to install, use and maintain, and can be applied to the transmission of low-frequency and high-frequency signals, and the contact is more reliable. CN202111501885.X discloses a radio frequency coaxial button adapter, which solves the problem of fixation by setting a rigid protective cap on the outside of the button, and can prevent the button from being permanently deformed by external force.
[0006] CN202111264751.0, CN201811451894.0, CN201720607346.7, and CN202111501885.X achieve the installation and protection of the wool buttons by adding a mechanism outside the wool button contact piece, but do not substantially solve the installation and protection problems of the wool buttons.
[0007] In view of the above problems, a wool button contact with different filling rates is designed. Summary of the invention
[0008] The present invention aims at solving the problems in the prior art and proposes the following technical solutions:
[0009] A hair button contact with different filling rates, comprising:
[0010] An interconnecting segment and a guarding segment connected at the ends, the filling rate of the guarding segment being greater than the filling rate of the interconnecting segment;
[0011] The filling rate of the interconnection segment is less than 50%, and the filling rate of the protection segment is less than 100%.
[0012] As a preferred embodiment of the above technical solution, the filling rate of the interconnection segment is between 15% and 30%;
[0013] The filling rate of the protection section is between 50% and 80%.
[0014] As a preferred embodiment of the above technical solution, the protection section includes a step 1 and a step 2 connected at the ends, the step 1 is connected to the interconnection section, and the cross-sectional shapes of the step 1 and the step 2 are consistent;
[0015] Alternatively, the cross-sectional shapes of the step 1 and the step 2 are inconsistent.
[0016] As a preferred embodiment of the above technical solution, the size of step one is consistent with that of the interconnection section, and the size of step two is smaller than that of step one.
[0017] As a preferred embodiment of the above technical solution, the interconnection segment and the protection segment are integrally and tightly wound.
[0018] As a preferred embodiment of the above technical solution, the material of the interconnection segment and the protection segment is any one of copper alloy, stainless steel, and molybdenum wire, and the interconnection segment and the protection segment adopt the same material.
[0019] The beneficial effects of the present invention are:
[0020] 1. A wool button contact with different filling rates in the technical solution is used for transfer interconnection between PCB boards. When installing the wool button contact, the wool button contact is placed inside the insulating mounting plate, the protective section is matched with the step mounting hole gap, and one end of the protective section is exposed to the outside of the insulating mounting plate, thereby solving the installation and fixation problem of the wool button contact.
[0021] 2. The technical solution provides a wool button contact with different filling rates. The interconnection section has a low filling rate, which can maintain the elasticity of the wool button contact and realize solderless interconnection between boards. The protective section has a high filling rate, so that the wool button contact has a certain rigidity, and after installation, the protective section with a certain rigidity is exposed to the outside of the insulating mounting plate to protect the elastic part of the wool button contact, thereby solving the problem that the wool button contact is easily deformed when in contact with external force. A protective section with a certain rigidity is provided on the wool button contact instead of providing a protective mechanism on the outside of the wool button in the prior art, so that the wool button contact itself has a protective function.
[0022] 3. In the technical solution, a wool button contact with different filling rates has an increase in the filling rate of the protective section, which increases the contact area per unit area, has a smaller contact resistance as a whole, and improves the interconnection reliability.
[0023] The technical solution of the present invention is a wool button contact with different filling rates. The interconnection section and the protection section are integrally formed by the same material. The protection section with a larger filling rate replaces the external protection mechanism and the installation mechanism, which substantially and simultaneously solves the problem of high resistance during the installation, protection and use of traditional wool button contacts.

[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.
[0028] Example 1
[0029] like Figure 1 As shown, a wool button contact with different filling rates includes: an interconnection segment 10 and a protection segment 20 connected at the ends, wherein the filling rate of the protection segment 20 is greater than the filling rate of the interconnection segment 10;
[0030] The filling rate of the interconnection segment 10 is less than 50%, and the filling rate of the protection segment 20 is less than 100%.
[0031] A hair button contact with different filling rates in the technical solution is used for transfer interconnection between PCB boards. When installing the hair button contact, Figure 2 As shown, the button contact is placed inside the insulating mounting plate 30, the protective section 20 is clearance-matched with the step mounting hole 31, and one end of the protective section 20 is exposed outside the insulating mounting plate 30, thereby solving the installation and fixing problem of the button contact;
[0032] The technical solution provides a wool button contact with different filling rates, wherein the filling rate of the interconnection section 10 is close to that of a conventional wool button, and the elasticity of the wool button contact can be maintained to achieve solder-free interconnection between boards; the protective section 20 has a high filling rate close to that of a solid cylinder, so that the wool button contact has a certain rigidity, and after installation, the protective section 20 with a certain rigidity is exposed to the outside of the insulating mounting plate 30, thereby protecting the elastic part (interconnection section 10) of the wool button contact and solving the problem that the wool button contact is easily deformed when in contact with external force; by providing a protective section 20 with a certain rigidity on the wool button contact instead of providing a protective mechanism on the outside of the wool button in the prior art, the wool button contact itself has a protective function, thereby substantially solving the protection problem of the wool button contact.
[0033] At the same time, the increase in the filling rate of the protection segment 20 increases the contact area per unit area, which results in a smaller contact resistance as a whole and improves the interconnection reliability.
[0034] The filling rate of the elastic part is generally controlled at 15% to 30%. If the filling rate of the wool button is too high, the rebound is not good; if the filling rate of the wool button is too low, it is easy to scatter. The filling rate of the non-elastic part needs to consider the factors of process realization, and the filling rate is 50% to 80%.
[0035] To ensure the stability of the wool button contact, Figure 1 As shown, the filling rate of the interconnection section 10 is between 15% and 30% to avoid the situation where the wool button contact has a too large filling rate and poor rebound, and the wool button contact has a too small filling rate and is easy to scatter, thereby ensuring that the wool button contact can make reliable contact after installation.
[0036] The filling rate of the protection segment 20 is between 50% and 80%. While the protection segment 20 has a rigid protection function, it also has a certain degree of flexibility, so that the wool button contact piece has higher stability when in contact with external components.
[0037] like Figure 1As shown, the protection section 20 includes a step 1 21 and a step 22 connected at the ends, and the step 1 21 is connected to the interconnection section 10. The cross-sectional shapes of the step 1 21 and the step 2 22 can be circular, rectangular, etc. At the same time, the cross-sectional shapes of the step 1 21 and the step 2 22 can be consistent; the cross-sectional shapes of the step 1 21 and the step 2 22 can also be inconsistent.
[0038] When installing the fur button contact, Figure 2 As shown, the wool button contact is placed inside the insulating mounting plate 30, the wool button contact as a whole is loosely matched with the insulating mounting plate 30, and the second step 22 passes through the step mounting hole 31 and extends to the outside of the insulating mounting plate 30, thereby improving the stability of the installation of the wool button contact.
[0039] like Figure 1 As shown, the step 1 21 is consistent with the size of the interconnection section 10, and the step 1 21 provides a support point for the interconnection section 10 to prevent external forces from acting on the interconnection section 10 and protect the interconnection section 10;
[0040] The size of the second step 22 is smaller than that of the first step 21 , and the second step 22 and the first step 21 form a stepped shape, which is clearance-matched with the step mounting hole 31 , thereby improving the stability of the installation of the wool button contact piece.
[0041] like Figure 1 As shown, the interconnection section 10 and the protection section 20 are integrally formed by tightly winding, so that the interconnection section 10 and the protection section 20 are truly integrated, and the wool button contact piece itself is used to achieve the functions of fixed installation and protection, which solves the problem in the prior art that it is necessary to use a structure added to the wool button contact piece to achieve fixed installation and protection.
[0042] The interconnection section 10 and the protection section 20 may be made of elastic materials such as copper alloy, stainless steel, molybdenum wire, etc. The interconnection section 10 and the protection section 20 are made of the same material.
[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
