Description

Spacer having detection function and connector having same {SPACER WITH DECTECTING FUNCTION AND CONNECTOR HAVING THE SAME}

The present invention relates to a spacer having a detection function, and more specifically, to a spacer having a detection function configured to detect the position of an erroneously assembled terminal when the spacer is inserted into a connector into which a terminal is inserted, and a connector having the same It is about.

In general, various control devices are arranged in automobiles to more effectively and efficiently control an engine that generates power to increase performance, satisfy various conditions, and further improve driver's convenience. These control devices are wire harnesses. By means of a normal connector is connected.

Most of the connectors as described above can be roughly divided into two types: a connector connecting wires to wires and a connector connecting wires to a board such as an electric junction box of a vehicle.

The connector connecting the wires to each other is one in which male and female connectors are coupled to each other so that the terminals of the connectors are connected to each other by being inserted into each other. These connectors have a locking function and are not separated from each other, but the terminals of the connectors are not well coupled in the process of being inserted into each other, so that the terminals are not well coupled, or the coupling position is misaligned, resulting in poor contact between the terminals and terminals. In order to prevent such a problem, a spacer for fixing the terminal has been developed and used.

However, since the spacer serves to fix the properly inserted terminal into the connector and does not have a function to properly insert the incorrectly inserted terminal, the operator must find the incorrectly inserted terminal and insert it properly again.

At this time, when inserting a spacer into a connector with a very large number of inserted terminals, if the spacer is not properly inserted due to an incorrectly inserted terminal, the operator must manually insert a large number of terminals to determine which terminal is incorrectly inserted. There was an inconvenience of having to check the terminal holes of the connector one by one.

In addition, when working on a wire harness that inserts terminals into connectors, it is not possible to check whether the terminals are correctly inserted into the correct positions of the connector, resulting in a high defect rate and lowering productivity. As the number of terminals inserted into the connector increases, the work efficiency increases. There were several problems, such as deterioration.

Hereinafter, some embodiments of the present invention will be described in detail through exemplary drawings. In adding reference numerals to components of each drawing, it should be noted that the same components have the same numerals as much as possible even if they are displayed on different drawings. In addition, in describing an embodiment of the present invention, if it is determined that a detailed description of a related known configuration or function hinders understanding of the embodiment of the present invention, the detailed description will be omitted.

Also, terms such as first, second, A, B, (a), and (b) may be used in describing components of an embodiment of the present invention. These terms are only used to distinguish the component from other components, and the nature, order, or order of the corresponding component is not limited by the term. When an element is described as being “connected,” “coupled to,” or “connected” to another element, that element may be directly connected or connected to the other element, but there may be another element between the elements. It should be understood that may be "connected", "coupled" or "connected".

The present invention will be described with reference to the accompanying drawings.

First, the configuration of the connector 1 and the spacer S of the present invention will be described.

In the connector 1, a plurality of terminal insertion holes 1a are formed in a row so that a plurality of terminals can be inserted. For convenience of description, the long axis shown in the drawing is defined as the X axis and row, and the short axis is defined as the Y axis and column. A hole is formed in the terminal insertion hole 1a to pass through the connector 1. A terminal (not shown) is inserted and fixed to the rear side of the connector 1, and a terminal (not shown) of the mating connector 1 is inserted to the front side to be electrically connected.

A spacer slot 1b is formed on a side surface of the connector 1 so that a spacer S can be inserted therein. When the spacer S is inserted into the spacer slot 1b, the terminals are fixed inside the connector 1 so that the terminals inserted into the terminal insertion hole 1a do not escape.

A locking hook 8 is formed adjacent to the spacer slot 1b formed on the side of the connector 1. The locking hook 8 is a part fixed to the spacer S inserted into the spacer slot 1b, and serves to prevent the spacer S from being separated after being coupled to the connector 1. .

Referring to FIG. 1 , confirmation grooves 1c are formed on both upper and lower sides of the connector 1 . The confirmation groove 1c is a hole formed in the front surface of the connector 1 so that the space inside the connector 1 is connected. In the confirmation groove 1c, the state of the spacer S inserted into the connector 1 can be visually confirmed.

Referring to FIGS. 2 to 5 , in the spacer S, the leg portion 20 integrally formed with the body portion 10 extends in one direction. The body portion 10 is divided into a handle portion 11 and a hinge portion 12. The handle part 11 is used when the user holds the spacer S and inserts or removes it into the spacer slot 1b of the connector 1. Preferably, the handle part 11 protrudes in a direction perpendicular to the direction in which the leg part 20 extends. This is because when the leg part 20 is formed perpendicularly to the direction in which the spacer slot 1b is inserted, it is easy for the user to apply force to and separate the handle part 11 . A locking protrusion 18 is formed at the center of the handle part 11 . When the spacer (S) is completely coupled to the connector (1), the locking protrusion (18) is caught on the locking hook (8) so that the spacer (S) is separated from the spacer slot (1b) of the connector (1). It serves to hold it in place.

The hinge part 12 connects the plurality of unit legs 21 to 24 constituting the leg part 20 with the body part 10, and the plurality of unit legs 21 to 24 are also connected to each other. connect Both sides of the hinge part 12 and the handle part 11 need not be fixed. Only one side of the handle part 11 may be fixed, and the unit legs 21 to 24 may be integrally formed by connecting them to each other.

The hinge part 12 is formed thinner than the handle part 11 or the leg part 20 and is bent in a spring shape, so that elasticity is generated. When elasticity is applied to the hinge part 12, each of the unit legs 21 to 24 constituting the leg part 20 is capable of independent movement, though limited. Therefore, if the leg portion 20 of the spacer S is not inserted yet and stops due to an incorrectly inserted terminal during insertion into the spacer slot 1b, the user moves the unit in the insertion direction of the spacer S. The legs 21 to 24 can be pressed and moved one by one. At this time, since each of the unit legs 21 to 24 can move independently by the elasticity given to the hinge part 12, it is possible to check the unit leg that does not move.

When the unit legs 21 to 24 are pressed, if there is a unit leg that is no longer inserted into the spacer slot 1b or does not move, the terminal of the row in which the corresponding unit leg is inserted is inserted into the terminal insertion hole 1a. You can check that it is inserted incorrectly.

Referring to FIG. 6, for example, when the first leg 21 is pressed in the direction of the arrow P, the terminal of the row in which the first leg 21 is inserted is properly inserted into the terminal insertion hole 1a. If it is, since there is no element obstructing the first leg 21, the first leg 21 advances as much as the arrow A. Conversely, if the terminal of the row in which the first leg 21 is inserted is incorrectly inserted into the terminal insertion hole 1a, even if the first leg 21 is pressed in the direction of the arrow P, the first leg 21 ) is blocked by the erroneously inserted terminal and cannot advance as much as the arrow A. The user presses each of the unit legs 21 to 24 in the direction of the arrow P to check whether each of the unit legs 21 to 24 move, thereby finding out the position of the row of the incorrectly inserted terminal.

The remaining second to fourth legs 22 to 24 are similarly pressed one by one, so that it can be checked whether the terminal of the row in which the corresponding unit leg is inserted is incorrectly inserted into the terminal insertion hole 1a. This is because the first to fourth legs 21 to 24 are elastically connected so as to be independently movable by the hinge part 12, respectively.

The hinge part 12 is integrally formed with the handle part 11 and the leg part 20, but may be formed thinner than the handle part 11 or the leg part 20 to provide elasticity, but the handle It can also be made by double injection with a material more flexible than the resin forming the part 11 or the leg part 20.

Although the present invention describes the hinge portion 12 to which elasticity is imparted as an example, the method is not particularly limited as long as the unit legs 21 to 24 of the leg portion 20 can move independently. For example, it is also possible that a plurality of links are connected to each other by hinges that rotate in a pivoting manner and move in a joint-driven manner.

The leg portion 20 elongates in a direction perpendicular to the direction in which the handle portion 11 protrudes. The leg part 20 is composed of a plurality of unit legs 21 to 24. For convenience of description, the embodiment of the present invention is composed of four unit legs, but it is natural that the number of unit legs can be changed according to the type of connector 1. In addition, it is preferable that the leg part 20 and the body part 10 be integrally injection molded.

Guide grooves 21a to 24a are formed on the surfaces of the first to fourth legs 21 to 24 along the longitudinal direction of the first to fourth legs 21 to 24 . Guide ribs (not shown) are formed in the spacer slot 1b of the connector 1 to correspond to the guide grooves 21a to 24a, and the first to fourth legs 21 to 24 are provided with the guide grooves. (21a to 24a) are combined with the guide rib to perform a sliding motion.

When the guide grooves 21a to 24a mesh with the guide ribs while the spacer S is inserted into the connector 1 and slide, the first to fourth legs 21 to 24 move to the connector 1 ), it can be inserted straightly while maintaining a straight direction without bending.

The first to fourth legs 21 to 24 are inserted into the spacer slot 1b of the connector 1 to fix the terminal inserted into the connector 1 so as not to be separated. When the spacer (S) reaches the terminal insertion hole (1a) where the terminal is not properly inserted, the first to fourth legs (21 to 24) stop entering at the same time. At this time, the front surface of the leg part 20 that has not yet been inserted is exposed to the outside of the connector 1, and the display part 30 is formed on the front surface of the first to fourth legs 21 to 24, respectively.

The display part 30 is formed on the front surface of the leg part 20 exposed to the outside, and it can be confirmed that a terminal corresponding to a column indicated by the display part 30 is incorrectly inserted into the terminal insertion hole 1a.

The display unit 30 is displayed in numbers (natural numbers). The number of the display units 30 displayed on the first to fourth legs 21 to 24 is equal to the number of terminal insertion holes 1a formed on the front surface of the connector 1 in the X-axis direction.

For example, if the number of terminal inserts 1a formed in the row into which the first leg 21 is inserted is 21, the first display unit 31 with numbers from 1 to 21 written on the first leg 21. ) is formed.

If the number of terminal inserts 1a formed in the row into which the second leg 22 is inserted is also 21, the second leg 22 has numbers from 1 to 21, as in the first leg 21. A displayed second display unit 32 may be formed. Alternatively, if the first leg 21 is written up to 21, the second display unit 32 may start from 22 and display up to 42.

The third leg 23 and the fourth leg 24 may also have a third display unit 33 and a fourth display unit 34 consistent with the numbers assigned to the second leg 22 .

The numbers formed on the display part 30 may be given so that larger numbers come from the front end of the unit leg toward the body part 10, or conversely, they may be given so that smaller numbers come. It is only necessary to check the number on the exposed front surface of the spacer (S) and distinguish the terminal inserted into the terminal insertion hole (1a) in question.

It is preferable that the display unit 30 is intaglio-molded with a laser or displayed so that numbers cannot be erased through double injection. However, it is also possible to display numbers by spraying or smearing ink on the leg part 20, and it is also possible to form a display part by attaching a number-displayed sticker to the leg part 20.

Meanwhile, a pressing portion (not shown) may be further formed at a front end of the unit leg at a portion connected to the hinge portion 12 . The pressing part is formed to protrude further from the outer surface of the body part 10, and provides convenience to the operation of pressing the unit leg.

Next, a process of distinguishing a terminal incorrectly inserted into the terminal insertion hole 1a with the spacer S of the present invention will be described.

Prior to the description, the position of the terminal insertion hole 1a of the connector 1 is defined. Referring to Figures 4 to 6, the terminal insert (1a) consists of five rows, the number of columns is different for each row. From the bottom of the connector 1 to the first row (1a ₁ ), the second row (1a ₂ ), the third row (1a ₃ ), the fourth row (1a ₄ ), and the fifth row (1a ₅ ), It is defined as the first to nth columns from the left to the right of the connector (1). The terminal insert 1a in the nth row (1a _n ) and nth column is defined as being at the nth,nth position (1a _n,n ). In the leg part 20, display parts 30 are formed from the first leg 21 part 20 to the fourth leg 24 at the bottom, and the third display part 33 of the third leg 23 ) is formed in two lines of numbers and is inserted to correspond to the two lines of the terminal insertion port 1a. However, it is not necessary that the third display portion 33 of the third leg 23 is formed in two lines.

Assume that a terminal is incorrectly inserted into the terminal insertion hole 1a marked with an 'X' shown in FIG. .

The leg part 20 is inserted into the spacer slot 1b of the connector 1. When the leg part 20 reaches the terminal insertion hole 1a at the 'X' position where the terminal is not properly inserted, the first to fourth legs 21 to 24 simultaneously prevent entry into the spacer slot 1b. will stop At this time, the front surface of the leg part 20, which has not yet been inserted, is exposed to the outside of the connector ₁ . stops entering when the numbers 11, 32, 53, 74, and 95 are exposed. The user can know the position of the row of the terminal insertion port 1a where the terminal is incorrectly inserted through the display unit 30, and can be specified as being at the nth and 11th positions 1a _{n and 11} .

The leg part 20 of the spacer S is formed of a plurality of unit legs 21 to 24, and each unit leg 21 to 24 is connected by the hinge part 12. Since the hinge part 12 is formed in the form of a spring having elasticity, it is possible for the unit legs 21 to 24 to move independently to some extent. The user may press the first to fourth legs 21 to 24 stopped at the n and 11th positions 1a _{n, 11} one by one in the insertion direction of the spacer S. Since the terminals inserted into the terminal insertion holes 1a of the second to fifth rows are properly inserted, the second legs 22 to the fourth legs 24 are placed in the spacer slots 1b of the connector 1. There are no factors that hinder Therefore, when each of the unit legs 21 to 24 is pressed in the insertion direction of the spacer S, the second to fourth legs 22 to 24 are moved in the insertion direction to some extent, but the first leg (21) is blocked by an incorrectly inserted terminal and does not move. The user can confirm that the first leg 21 does not move even when pressed and determine that the terminal inserted in the first row has a problem.

That is, through the fact that the number 11 exposed on the first display unit 31 and the first leg 21 do not move, the user believes that the terminals inserted in the first and eleventh positions 1a 1 _{and 11} are incorrectly inserted. You can figure out what it is, and you can separate the terminal at that location and insert it again so that it is well combined.

In the above, even though all the components constituting the embodiment according to the present invention have been described as being combined or operated as one, the present invention is not necessarily limited to these embodiments. That is, within the scope of the object of the present invention, all of the components may be selectively combined with one or more to operate.
