Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a plug and a receptacle of an electrical connector, and an electrical connector assembly including the plug and receptacle,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrical connector, and more particularly, to an electrical connector and an electrical connector assembly including the same, which provide a flat structure by lowering the structure of the electrical connector and provide a more simple and durable fastening means.

The connector device is used for electrically connecting a circuit board, a circuit board, or a circuit board with an electronic component using a cable.

2. Description of the Related Art In recent years, a connector device has been widely applied to a circuit board such as a portable terminal, and a low profile is required to meet the trend of miniaturization of electronic devices. In addition, as the density of electronic elements mounted on the circuit board increases, the number of contacts provided in the connector apparatus increases, and densification of contact pitch pitches becomes more important.

1, a plurality of receptacle contacts 12 are fitted in a receptacle 10 and a receptacle 10 arranged in a main body 11, and a plurality of receptacle contacts 12 are inserted into receptacle contacts 12, And a plug contact (22) which is in one-to-one contact with the plug (20). The receptacle contacts 12 and the plug contacts 22 are connected to the receptacle-side cable and the plug-side cable, respectively, or are mounted on the circuit board. The receptacle side cable and the plug side cable or circuit of the circuit board are electrically connected when the plug 20 is fitted into the receptacle 10 and the receptacle contact 12 and the plug contact are brought into mutual contact and conduction.

The conventional connector device as described above can not be fastened to the entire connector device even if one of the plurality of plug contacts 22 or the receptacle contacts 12 is damaged and can be easily broken by insertion in the wrong direction .

Further, since the plug contacts 22 are fastened to the receptacle contacts 12 in a one-to-one manner, there is a problem that the structure is complicated and is not suitable for low-profile.

In order to lower the height of the plug connector 22 and the receptacle contact 12, the length (height) of the plug connector 22 and the receptacle contact 12 must be shortened. However, the plug connector 22 and the receptacle contact 12 have a shortened length. There is a limit to the lowering of the connector device of the conventional structure due to the above problems.

Korean Patent Application No. 10-2013-0124561

1, the receptacle contacts 12 of the receptacle 10 and the plug contacts 22 of the plug 20 have a bended structure in order to ensure mutual contact reliability And if the effective contact length over a certain distance is reduced, there is a problem that the degree of failure between the two connectors is significantly lowered, thereby increasing the defective rate during the assembling process of the product.

In order to solve this problem, Application No. 10-2013-0124561 discloses an electrical connector comprising an insulator for electrical insulation and a plurality of contacts provided on the insulator for providing an electrical connection, A contact portion protruding from the upper surface of the insulator for electrical contact with the electrical connection terminal; a buried portion embedded in the insulator; and a lead portion for connection with the substrate, wherein the contacts are formed on the insulator in accordance with a predetermined pitch Wherein a contact row formed by the contacts has a variable pitch at which a pitch between the contacts is varied by an applied tension, and the insulator includes: Is formed of a soft insulator which is stretchable or contractible in accordance with an applied tension, And has a surface adhesive force for maintaining a contact state during contact of the tact. Accordingly, it is an object of the present invention to provide a bonding means which maintains an adhesive force for a long time and has high durability, in comparison with the above-mentioned prior art.

The present invention provides a plug 100 of an electrical connector assembly including a plug 100 and a receptacle 200. The plug 100 includes a flexible printed circuit (FPC) 110, A circuit board 120 electrically connected to the circuit board 120 and electrically connected to the circuit board 120. The circuit board 120 includes a circuit board 120 printed on the circuit board 110, an insulation plate 130 formed on the bottom of the flexible circuit board 110, A guide frame 210 for receiving the insulating plate 130, an insulator 220 installed at the bottom of the guide frame 210, And a receptacle contact (230) provided on the insulator (220) and having a lead portion (232) protruding outside the guide frame (210).

In the plug and the receptacle, one side of the insulating plate 130 and the insulator 220 is made of an adhesive polymer material and one side is made of glass, thereby making use of the adhesive force of the adhesive polymer .

Adhesive polymers, such as silicone rubber, provide a higher adhesion when in contact with the glass ("indirect" contact) than in contact with the silicone rubber ("direct") and have higher durability The adhesive force can be maintained for a long period of time even if the fastening and separation are repeated.

Further, according to the present invention, since the elastic protrusion 131 is formed adjacent to the distal end portion of the contact provided on the adhesive polymer, the elastic protrusion is pressed upon tightening so that the contact protrudes while pushing the contact, .

According to the present invention, it is possible to realize an electrical connector with an extremely low profile by applying a structure in which a structure of the electrical connector is flat and a structure capable of holding and holding by bonding between both planes. In addition, since the contact between the contacts can be made without depending on the contact banding structure, the contact structure can be designed in a simple form and the engagement and retention can be achieved by bonding between the planes, And the manufacturing cost can be reduced.

Further, the present invention is based on the experimental results that the tensile bond strength between the glass-mediated adhesive polymer and the glass is stronger than the tensile bond strength due to the direct adhesion between the adhesive polymers. The above tests compare the strengths when they are adhered to each other and when dropped, comparing the 'indirect' adhesion of the adhesive polymer to the 'direct' adhesion of the adhesive polymer to the glass. According to the above test, the tensile bond strength of the adhesive polymers was 264.9 gf / 24 mm ² , but the tensile bond strength of the adhesive polymer and glass was 455.2 gf / 24 mm ^{2 at} the maximum. Thus, it can be seen that the tensile bonding strength between the adhesive polymer through glass and the glass is stronger than the tensile bonding strength due to the direct bonding between the adhesive polymers.

Based on the above-described experimental results, one side of the connector assembly fastening means is made of glass and the other side is made of an adhesive polymer, so that a stronger adhesive force can be expected in tightening the plug and the receptacle than when only the adhesive polymer is applied have.

In addition, according to the present invention, the elastic protrusion is formed adjacent to the distal end portion of the contact provided on the adhesive polymer, so that the elastic protrusion is pressed upon tightening so that the contact is pushed up to secure a stable electrical contact.

According to such a configuration, the present invention provides the advantage of providing a higher fastening stability and durability and maintaining the adhesive strength for a long period of time even if the fastening and separation are repeated many times.

Field of the Invention The present invention relates to an electrical connector, and more particularly, to an electrical connector and an electrical connector assembly including the same, which provide a more stable and durable fastening means by lowering the structure of the electrical connector. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

2 is a perspective view of an electrical connector of the present invention. 2, a circuit pattern 120 is printed on a flexible printed circuit (FPC) 110 of a plug 100 of an electrical connector assembly of the present invention, and the flexible circuit board 110, An insulating plate 130 is provided at the bottom of the housing. The flexible circuit board 110 is generally formed of a polyimide (PI) material, but the present invention is not limited thereto. The circuit pattern 120 may be formed by adhering a copper foil constituting the circuit pattern 120 and a polyimide (PI) film of the flexible circuit board 110 to each other. Alternatively, (PI) film can be directly die-casted or bonded at a high temperature. However, in the present invention, the method of printing the circuit pattern 120 on the flexible circuit board 110 is not limited to a specific printing method.

The insulating plate 130 is made of an adhesive polymer, and the adhesive polymer will be described later in detail.

The insulator plate 130 is inserted into the space to be brought into contact with the insulator 220 and an adhesive force is generated at the contact surface to bind the plug 100 and the receptacle 200. The contacts 140 provide electrical contact with the receptacle contacts 230 and electricity through the receptacle contacts 230 is in communication with the exterior of the connector through the lead portions 232. At this time, it is necessary to reduce the surface area of the contact 140 and the receptacle contact 230 in order to ensure higher adhesive strength. The contact 140 and the receptacle contact 230 may be formed so as to be buried in the insulating plate 130 and the insulator 220 such that the contact surfaces of the insulating plate 130 and the insulator 220 are parallel to each other desirable. However, excessive burial installation should be avoided as it may reduce reliability of electrical contact maintenance. Although not shown in FIG. 3, the circuit pattern 120 is electrically connected to the upper surface of the contact 140.

3 (a), in order to provide a higher fastening stability, an elastic protrusion 131 is formed adjacent to the terminal end of the contact 140 on the bonding surface of the insulating plate 130 And a distal end portion of the contact 140 may be formed as a curved portion 141. The above-described structure allows the elastic protrusion 131 to be pushed to push the curved portion 141 to protrude the contact, thereby making it possible to form the electrical contact more stably. In the same way, the above-mentioned elastic projection can be applied to the receptacle. 3 (b), when the insulator 220 of the receptacle 200 is formed of an adhesive polymer, the elastic protrusions 221 are provided adjacent to the distal end of the receptacle contacts 230 Can be installed. In this case, it is preferable that the receptacle contact 230 has a curved portion 231 as described above.

As shown in FIG. 4, the contact 140 may be configured to be fixed by applying a soldering 150 through a flexible circuit board (FPC) 110. In FIG. 4, the circuit pattern 120 is not shown and may be electrically connected to the upper surface of the contact 140.

5 is an explanatory view showing an embodiment of the connector assembly of the present invention in which the insulating plate 130 is made of silicone rubber and the insulator 220 is made of glass.

The silicone rubber has an advantage that an adhesive force is generated while being in contact with the glass, and no additional components such as an adhesive are required.

The silicone rubber preferably has a composition ratio of 10-30% of methylhydrogenpolysiloxane, 30-60% of silicone resin, and 30-60% of polyvinylsiloxane.

6 is a graph showing an experimental result on the adhesive force of the silicone rubber. As shown in the graph of FIG. 6, by making the silicone rubber of the insulating plate 130 contact with the glass of the insulator 220, it is possible to expect a higher adhesive force than the adhesive force of direct contact between the silicone rubber and the silicone rubber. Particularly, the silicone rubber among the adhesive polymers has an advantage that the adhesive strength is not deteriorated even after several bonding, as well as good adhesive strength.

The present inventors have confirmed through experiments that the silicone rubber of the adhesive polymer shows a higher adhesive strength than when the adhesive polymers are in contact with the glass. The results of the experiment are shown in Table 1 below.

Name of sample Experiment Item unit Experiment result #One Tensile bond strength gf / 24 mm ² Direct: 246.6

Indirect: 94.7

The results of the experiments are as follows: "Direct" refers to the adhesion between the adhesive polymers, and "indirect" refers to the adhesion between the adhesive polymer and glass Lt; / RTI >

The experiment was conducted under the following conditions.

(1) Tester: UTM, WL2100 (WITHLAB, Korea)

(2) Test speed: 5 mm / min

(3) Load cell: 20 N

(4) Spacing: 115 mm

(5) Test environment: (25 ± 2) ° C, (60 ± 5)% RH (at the time of test, 26 ° C and 59% RH)

(The adhesive material is in the form of a dome)

As a test method, a probe tack was applied to construct the sample. That is, the upper adhesive layer and the lower adhesive layer were adhered only to the weight of the upper test sample, and then the experiment was conducted.

According to the results of the above test results, the tensile adhesion strength of the adhesive polymer and glass through glass was recorded at a maximum of 455.2 gf / 24 mm ² . In other words, the adhesive strength of the adhesive polymer and the glass through glass is more strong than the tensile adhesion strength due to the direct adhesion between the adhesive polymers.

It goes without saying that the strength can be controlled according to the curing conditions and the size of the adhesion surface of the sample.

According to the graph of FIG. 6 which summarizes the above experimental results, in the case of 'indirect', especially in the experiment of # 2, it shows a predominant adhesion with a large difference, and similar or improved It can be confirmed that the adhesive strength is shown.

It is most preferable to apply the silicone rubber as described above. However, the present invention is also applicable to a composition in which a composition obtained by mixing an acryl copolymer and a heat-resisting polymer resin in place of the silicone rubber is applied to provide. In this case, the acrylic copolymer may be selected from the group consisting of 2-ethyl hexyl acrylate, butyl acrylate monomer, methyl acrylate, ethyl acrylate monomer, Methyl methacrylate, n-butyl methacrylate, n-hexyl methacrylate, acrylic acid, methacrylic acid, and the like. at least two monomers selected from copolymers obtained by copolymerizing two or more monomers selected from the group consisting of maleic acid, itaconic acid and 2-hydroxyethyl methacrylate (2-HEMA) And the heat resistant polymer resin is preferably selected from the group consisting of cresol novolac epoxy, phenol novolac epoxy, bisphenol-A type epoxy, During scan -F type epoxy phenol (bisphenol-F type epoxy), phenoxy resin (Phenoxy resin), naphthalene type epoxy resin (naphthalene type epoxy resin) it can be applied to select one or more. The composition of the acrylic copolymer and the heat-resisting polymer resin is similar to the silicone rubber as the adhesive polymer.

In addition, in the case of the above-mentioned 'indirect' adhesion, it is most preferable to apply glass as described above. However, the present invention is further applicable to a silica- (POM), polybutylene terephthalide (PBT), acrylic resin, and the like, which are treated with a high-gloss resin, such as High Gloossy, such as nylon resin, polycarbonate (PC), polyphenylene oxide (PPO), polyoxymethylene Lt; RTI ID = 0.0 > and / or < / RTI >

Fig. 7 is an explanatory view showing another embodiment of the connector assembly of the present invention, and Fig. 8 is a perspective view of the embodiment of Figs. 3 (b) and 7 (a). As shown in FIG. 3B, FIG. 7A and FIG. 8, the insulating plate 130 may be made of glass. That is, the plug 100 is a plug having a glass or an insulating plate 130 made of glass as described above, and the receptacle 200 is an insulator of the adhesive polymer material described above. And a receptacle having a receptacle 220. As the adhesive polymer, it is preferable to apply the silicone rubber as described above.

7 (a), an insulator 220 composed of the above-described insulating polymer of the receptacle 200 is connected to the insulator 220 of the plug 100 via a glass So that the plug 100 and the receptacle 200 are coupled with each other by a strong adhesive force ('indirect').

In this case, as the glass is applied to the plug 100, fixing means between the glass and the flexible circuit board 110 must be considered. An adhesive or an external fixing means may be applied. In addition, since glass is a relatively easy material to break, it may be damaged when applied to a plug having a higher movement tendency than a receptacle. Accordingly, means for improving the durability such as limiting the size, thickness and material of the glass can be considered. The insulator 220 is made of an adhesive polymer material so that an elastic protrusion 221 is provided adjacent to the distal end of the receptacle contact 230 on the contact surface of the insulator 220, May be formed as a curved portion 231. As described above, such a configuration allows the electrical contact to be stably secured by protruding the receptacle contact 230 at the time of fastening, thereby providing a higher fastening stability.

7 (b), the plug 100 is a plug having an insulating plate 130 made of the adhesive polymer material described above, and the receptacle 200 is also bonded It is of course also possible to construct an electrical connector assembly which is a receptacle with an insulator 220 of a polymeric material. This case corresponds to the bond between the adhesive polymers shown in Table 1 and the graph of FIG. 6, and thus provides an adhesive force corresponding to a 'direct' bond. As shown in the graph of FIG. 6 and in Table 1, the 'direct' bond between the adhesive polymers is inferior to the 'indirect' bond between the glass-mediated adhesive polymer and glass. However, instead of glass which is easy to break, durability and workability are merely advantageous in that it is easy to manufacture and maintain by applying only the adhesive polymer.

The receptacle 200 of the electrical connector assembly including the plug 100 and the receptacle 200 of the present invention includes a guide frame 210 for receiving the insulating plate 130. The guide frame 210 may be made of a metal or a polymer material and is preferably an insulator. An insulator 220 is installed on the bottom of the guide frame 210 and a receptacle contact 220 having a lead portion 232 protruding out of the guide frame 210 230 are installed.

The insulator 220 may be composed of an adhesive polymer material or glass so that in order to apply an 'indirect' bond between the adhesive polymer and the glass, The material of the plate 130 is determined. That is, when the insulator 220 is made of a glass material, the plug 100 must be provided with an adhesive polymer. In this case, the insulating plate 130 of the plug 100 is made of an adhesive polymer .

The adhesive polymer constituting the insulating plate 130 may be composed of a silicone rubber. The silicone rubber may have properties such as the above-described materials, density, tensile strength, tear strength, linear shrinkage, turbidity, . The receptacle contact 230 is in electrical contact with the contact 140 of the plug 100 and the electrical signal received from the contact 140 of the plug is communicated with the outside through the lead portion 232 do.

The present invention can be applied to a configuration in which the insulating plate 130 of the plug is inserted and fastened between the two guide frames 210 of the receptacle 200 as shown in FIG. In such a structure, the two receptacles 200 and the insulating plate 130 have the same structure as the sandwich, and the pair of receptacles 200 are engaged with each other, so that the insulating plate 130 can be strongly fixed. If necessary, the pair of guide frames 210 may include a concave-convex structure corresponding to each other so as to engage with each other, thereby giving stronger binding force.

In this configuration, the insulating plate 130 itself can be a plug 100, a printed circuit board can be directly connected, and an electrical connecting means can be added thereto. For example, the flexible circuit board 110 may be inserted through a central portion of the insulation plate 130. In this case, the flexible circuit board 110 is interposed between the pair of insulation plates 130, Contacts 140 that are in electrical contact with the circuit board 110 may be respectively installed on the insulating plates on both sides.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it should be understood that various changes and modifications will be apparent to those skilled in the art. It is to be understood that the present invention is not limited to the above-described embodiments. Accordingly, the scope of protection of the present invention should be construed according to the following claims, and all technical ideas which fall within the scope of equivalence by alteration, substitution, substitution, Range.
