Description

Technical Field

[0001] The utility model relates to the technical field of female connectors, in particular to a female connector which can be easily broken into required number of positions. Background Art

[0002] The female connector is a universal connection device widely used in electronics, electrical appliances and instruments. It mainly plays the role of current or signal transmission. Since the specifications used in different electronic products are not exactly the same, there are many types of female connectors. According to the number of rows, there are single-row female connectors, double-row female connectors, triple-row female connectors, etc.; each row of female connectors consists of multiple side-by-side terminals.

[0003] When in use, the terminals at the bottom of the female connector are generally connected to the connection holes on the circuit board or other equipment, and the jacks at the top are connected to the wiring harness to transmit current or signals.

[0004] During the use of the female row connector, since the number of terminals on the bottom female row is fixed, when the number of female row terminals is not equal to the number of connection holes on the circuit board or other equipment, if the number of female row terminals is less than the number of connection holes, it can be solved by adding a female row connector. However, if the number of female row terminals is greater than the number of connection holes, the existing female row connector cannot break the shell according to the actual scenario and adjust the number of female row terminals to the corresponding number of connection holes, that is, the number of female row terminals of the female row connector cannot be broken to the required number of bits, resulting in limited usage scenarios of the female row connector.

[0005] In view of this, we propose a female header connector which is easy to break into the required number of positions. Utility Model Content

[0006] The purpose of the utility model is to solve the problem in the prior art that the shell cannot be broken according to the actual scenario to adjust the number of female terminals to the corresponding number of connection holes, that is, the number of female terminals of the female connector cannot be broken to the required number of positions, and a female connector that is easy to break to the required number of positions is proposed.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A female connector which is easy to break to the required number of digits comprises a shell, wherein the shell is designed in multiple groups, and two adjacent groups of the shells are connected by a main connecting block; a gap groove is provided between two adjacent groups of the shells, and the main connecting block is located in the gap groove.

[0009] Preferably, the main connection block is flush with the top of the housing.

[0010] Preferably, auxiliary connection blocks are connected between two adjacent groups of the housings; there are two groups of auxiliary connection blocks, and the auxiliary connection blocks are located on both sides below the main connection block.

[0011] Preferably, grooves are provided on both side walls of the main connection block and the auxiliary connection block.

[0012] Preferably, the cross section of the groove is triangular.

[0013] Preferably, both the main connection block and the auxiliary connection block are provided with a strip-shaped through hole, and the strip-shaped through hole and the groove are in the same plane.

[0014] Preferably, the side walls of the main connection block and the auxiliary connection block are stepped.

[0015] Preferably, the side walls of the main connection block and the auxiliary connection block are inclined.

[0016] Preferably, the cross section of the auxiliary connection block is circular.

[0017] Preferably, the number of the shells is 5-50 groups.

[0018] Compared with the prior art, the utility model provides a female connector that is easy to break into the required number of positions, and has the following beneficial effects:

[0019] 1. The female connector which is easy to break to the required number of positions has gap grooves on both sides of the shell. During the breaking process, the shells on both sides of the gap grooves will tilt to both sides, the gap groove spacing on one side will be reduced, and the gap groove spacing on the other side will be expanded until the main connecting block is broken, so as to achieve the purpose of adjusting the number of female terminals to the corresponding number of connecting holes, that is, the purpose of breaking the female connector to the required number of positions.

[0020] 2. The female connector which is easy to break to the required number of positions has three-point support formed between the main connection block and the auxiliary connection block, which improves the overall stability and avoids shaking when the number of shells is too large. At the same time, because the auxiliary connection blocks are located on both sides of the main connection block, they are not on the same straight line in the vertical direction. Therefore, during the breaking process, the auxiliary connection block on the side where the gap groove spacing is enlarged will break first, and then the main connection block in the middle will break, and finally the auxiliary connection block on the side where the spacing is reduced will break. The auxiliary connection block and the main connection block will break in turn, reducing the difficulty of breaking.

[0021] 3. The female connector, which is easy to break to the required number of positions, is designed with grooves and strip-shaped through holes. During the breaking process, the main connecting block and the auxiliary connecting block are easier to break and will break along the grooves, which can prevent the fracture zone from tilting during the breaking process.

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0029] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0030] Example:

[0031] Reference Figure 1-Figure 5 A female connector which is easy to break into the required number of positions comprises a housing 1, the housing 1 is designed in multiple groups, the number of housings 1 is 5-50 groups, preferably 20 groups, each housing 1 is provided with a female terminal 101 at the bottom, each housing 1 is provided with a socket 102 at the top, the female terminal 101 is used to connect with the connection hole on the circuit board or other equipment, and the socket 102 is used to plug the wiring harness.

[0032] Two adjacent sets of housings 1 are connected by a main connection block 201, which is flush with the top of the housing 1 to improve the appearance. Figure 2 and Figure 3 There is a gap groove 2 between two adjacent groups of shells 1, the width of the gap groove 2 is between 0.2-0.5 cm, both sides of the shell 1 have a gap groove 2, and the main connecting block 201 is located in the gap groove 2.

[0033] During use, if the number of female terminals 101 is greater than the number of connection holes on the circuit board or other equipment, the staff will count from one end of the female connector, and after counting the corresponding number, the staff will manually break it off from the corresponding gap slot 2 and break it to the required number of bits, so that the number of female terminals 101 is the same as the number of connection holes on the circuit board or other equipment, and it can be flexibly applied to various practical scenarios to achieve plug-in.

[0034] During the breaking process, hold the housing 1 on both sides of the gap groove 2 to be broken with both hands. Figure 1-Figure 2 , bend horizontally through the gap grooves 2 on both sides of the shell 1. During the breaking process, the shell 1 on both sides of the gap grooves 2 will tilt to both sides, the spacing of the gap grooves 2 on one side will be reduced, and the spacing of the gap grooves 2 on the other side will be expanded until the main connecting block 201 is broken, thereby achieving the purpose of adjusting the number of female terminals 101 to the corresponding number of connecting holes, that is, breaking the female connector to the required number of digits.

[0035] like Figure 3-Figure 5 Auxiliary connection blocks 202 are also connected between two adjacent groups of housings 1; there are two groups of auxiliary connection blocks 202, and the auxiliary connection blocks 202 are located on both sides below the main connection block 201.

[0036] The main connection block 201 and the auxiliary connection block 202 are not in contact with each other, and the auxiliary connection block 202 is also located in the gap groove 2 .

[0037] Three-point support is formed between the main connection block 201 and the auxiliary connection block 202 to improve the overall stability and prevent the housing 1 from shaking when there are too many of them. At the same time, because the auxiliary connection blocks 202 are located on both sides of the main connection block 201, they are not on the same straight line in the vertical direction. Therefore, during the breaking process, the auxiliary connection block 202 on the side where the spacing of the gap groove 2 is enlarged will break first, and then the main connection block 201 in the middle will break, and finally the auxiliary connection block 202 on the side where the spacing is reduced will break. The auxiliary connection blocks 202 and the main connection blocks 201 will break in turn, reducing the difficulty of breaking.

[0038] The main connection block 201, the auxiliary connection block 202 and the housing 1 are integrally formed by injection molding.

[0039] like Figure 3-Figure 5The side walls of the main connection block 201 and the auxiliary connection block 202 are provided with grooves 3, and the cross section of the groove 3 is triangular.

[0040] The groove 3 is located at the position of the fracture zone.

[0041] During the breaking process, the main connecting block 201 and the auxiliary connecting block 202 are broken in sequence. Due to the design of the groove 3, they are easier to break and will break along the groove 3, which can prevent the fracture zone from tilting during the fracture.

[0042] Both the main connection block 201 and the auxiliary connection block 202 are provided with a strip-shaped through hole 301 , and the strip-shaped through hole 301 and the groove 3 are in the same plane.

[0043] The strip-shaped through hole 301 can ensure the flatness of the fracture zone, further prevent the fracture zone from tilting during fracture, and reduce the difficulty of breaking.

[0044] like Figure 3-Figure 5 The side walls of the main connecting block 201 and the auxiliary connecting block 202 are stepped 4, or the side walls of the main connecting block 201 and the auxiliary connecting block 202 are inclined 401, or the cross-section of the auxiliary connecting block 202 is circular, or one of the side walls of the main connecting block 201 and the auxiliary connecting block 202 is stepped 4 and the other is inclined 401.

[0045] By designing the side walls of the main connecting block 201 and the auxiliary connecting block 202 to be not flush, during the breaking process of the main connecting block 201 and the auxiliary connecting block 202, the side walls of the main connecting block 201 and the auxiliary connecting block 202 are not broken at the same time, but are broken in sequence, thereby further reducing the difficulty of breaking.

[0046] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
