Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a connector incorporating electronic elements such as diodes and resistors.

[Conventional technology]

2. Description of the Related Art Connectors with built-in electronic elements are known, which provide electrical functions such as surge prevention in addition to connection functions by incorporating electronic elements between the terminals of the connector.

Conventional examples thereof are shown in FIGS. 4 and 5. In these figures, 11 is a male connector housing;
2 is a female connector housing, 13 is a male terminal, 14
1 is a female terminal, and 15 is an electronic element.

This electronic element built-in connector is manufactured as follows. One lead wire 15 of the electronic element 15
A and the wire 16 from which the sheathing has been removed are connected to the rubber waterproof plug 1.
7 is inserted, it is caulked and fixed to the connecting part 13a of the male terminal, and further soldering is performed from above.
Perform the above operation for the other male terminal in the same way, and place the electronic element 15 between both male terminals 13, 13.
Connect. The male terminal 13 connected in this way,
13 into a predetermined position within the connector housing 11. Thereafter, in order to fix and protect the electronic element 15, an epoxy resin 18 is injected into the element storage chamber 11a provided at the rear part of the connector housing and hardened, thereby completing the electronic element built-in connector.

[The problem that the idea aims to solve]

However, in the above method, the lead wire 15a of the electronic element 15 must be inserted into the rubber waterproof plug 17, and soldering must be performed to improve the contact reliability of the caulked portion, which is very time-consuming. Additionally, as electronic elements become smaller, work becomes more difficult.
Miniaturization is difficult because work efficiency decreases. Furthermore, the epoxy resin 18 had to be cured at high temperature for a long time (approximately 70° C. for about two hours), resulting in poor productivity. Furthermore, when the element 15 is destroyed, it is impossible to replace only the element 15 alone.

The present invention aims to eliminate the drawbacks of the above-mentioned conventional technology, and aims to provide a connector with a built-in electronic element that has a simple configuration, facilitates assembly work, is miniaturized, and allows only the element to be replaced. It is said that

[Means to solve the problem]

In order to achieve the above object, the electronic element built-in connector of the present invention has male and female connector housings,
It consists of a space bored inside one of these from the fitting surface side to expose a plurality of terminals, and an electronic element fitted in the space and equipped with a plurality of elastic contact terminals, Each of the contact terminals is configured to be pressed into contact with a different terminal within the connector.

Alternatively, the space inside the connector may be sealed from the outside of the electronic element with waterproof packing.

[Effect]

The operation of the present invention will be explained with reference to FIGS. 1 and 2. The electronic element 3 includes a plurality of elastic contact terminals 3b, 3b. These are pressed into contact with the plurality of terminals 4, 4 in the connector housing 1, respectively. In this way, the electronic element 3 is housed within the space 1d within the connector housing 1. Thereafter, by fitting the mating connector housing 2, the electronic element built-in connector is completed.

Before mating with the mating connector, the open part 1f of the space 1d is closed and sealed with packing 8, if necessary.

This eliminates the work required in the past, such as caulking the lead wires of electronic devices at terminal connections, soldering, and injecting epoxy resin, and also eliminates the need for curing time for the resin.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings. In FIGS. 1 and 2, 1 is a female connector housing, 2 is a male connector housing, and 3 is an electronic element such as a diode or a resistor. The male and female connector housings 1 and 2 are fitted with the electronic element 3 interposed therebetween as will be described later, and the locking protrusion 2a of the locking arm is fitted into the locking hole 1a and locked, and the electric wires 5, 5, 6, and 6 are connected with the electronic element 3 interposed therebetween.

A female terminal (not shown) is fitted into a terminal accommodating chamber of the male connector housing 2, and an electric wire 6 is connected thereto. On the other hand, two male terminals 4, 4 are fitted and locked into the respective terminal accommodating chambers 1b of the female connector housing 1. An electric wire 5 is crimped and caulked to the electric wire connection portion 4a at the rear end of the male terminal 4. A waterproof plug 7 is provided at a position where the connected electric wire 5 exits from the terminal storage chamber 1b to prevent water from entering the connection portion from the rear end.

A space 1d for accommodating the electronic element 3 is bored from the fitting surface 1c side of the terminal accommodating chamber 1b from the fitting surface 1c side.
connected to. These mantle portions 1e and space 1
d, there is no particular reason why the boundary must be clear, and a part of the mantle body portion 1e may be made into a space 1d.

The electronic element 3 has a molded main body 3a.
and contact terminals 3b, 3b. The contact terminal 3b is made of a flat plate-like elastic material, and is attached to the main body 3.
It protrudes on both sides from the end of a, curves downward, and further curves inward to form a press-contact part. The male terminal 4 is inserted between the contact terminal 3b and the main body portion 3a to make a press-contact connection, but since the contact terminal 3b has a flat plate shape, the contact force is large and soldering is unnecessary. The electronic element 3 is pushed in from the fitting surface 1c side and is housed in contact with the bottom of the space 1d. After that, if necessary, packing 8 is fitted into the space 1d to provide a waterproof structure. The electronic element 3 is not limited to single-function elements such as diodes and capacitors, but may be a combination of internal circuits. In addition, the contact terminal 3 having elasticity
A configuration may be adopted in which three or more b are provided.

In this way, the electronic element 3 is connected by the elasticity of the contact terminal 3b and can be easily fitted into the connector housing, so even if the element is made smaller and the pitch between the terminals is reduced, the work becomes difficult. Never. Furthermore, the present invention is not limited to male terminals, but can also be applied to female terminals.

FIG. 3 is a diagram showing a pressure contact structure between the electronic element 3 and the male terminal 4. a is the same as shown in FIGS. 1 and 2. It is also possible to have a configuration in which the male terminal 4 is pressed into contact from one side as shown in b. When the mating terminal is a female terminal, it is easier to manufacture the connector housing by using a pressure contact structure as shown in b.

[Effect of idea]

As explained above, according to the present invention, it is only necessary to insert the electronic element when fitting a normal connector housing, and it is possible to obtain a connector with a built-in electronic element extremely easily. Moreover, even if an element is damaged, only the element can be replaced, reducing maintenance costs. In addition, the element has a structure in which contact terminals are provided on a molded element, and since it is only necessary to insert the element, the workability is not affected even if the element is small, and miniaturization can be achieved. moreover,
It is also possible to combine the internal circuitry of the electronic element to create a connector with multiple functions.
